    Background and purpose: Research in formative assessment often pays close attention to the strategies which can be used by teachers. However, less emphasis in the literature seems to have been paid to study the application of formative assessment designs in practice. In this paper, we argue...... that a formative assessment design that we call Eva-Mapping, which is developed on the principles of design-based research, can be a productive starting point for disseminating and further developing formative assessment practices in outdoor science teaching. Sample, design and methods: We conducted an evaluation...... of the design, based on video-elicited focus group interviews with two groups of experienced science teachers. Both groups consisted of teachers who taught science outside the classroom on a regular basis. These groups watched identical video sequences which were recorded during lessons in which teachers...

    The focus of this study is to examine to what extent and in what ways science teachers practice assessment during classroom interactions in everyday activities in an upper-secondary school in Sweden. We are science teachers working now with a larger research project on assessment in science education that seeks to examine teachers' assessment practices in the upper-secondary school. Framing questions include: are teachers performing an integrated assessment of students' skills as the national curriculum mandates? If so, what do the instructional discourses look like in those situations and what are students' experiences regarding their agency on learning and assessment? We emphasize the social, cultural and historic character of assessment and sustain a situated character of learning instead of the notion that learning is "stored inside the head". Teacher led lessons in three science classrooms were video-recorded and analyzed by combining ethnographic and discourse methods of analysis. Both methods are appropriate to the theoretical foundation of our approach on learning and can give some answers to questions about how individuals interact socially, how their experience is passed on to next generations through language and how language use may reveal cultural changes in the studied context. Making the study of action in a classroom the focal point of sociocultural analysis supports the examination of assessment processes and identification of the social roles in which teachers and students are immersed. Such an approach requires observations of how teachers act in authentic teaching situations when they interact with their students in classroom making possible to observe negotiation processes, agencies when both teachers and students are involved in every-day activities. Our study showed that teachers mostly ignored students' questions and that students solved their own problems by helping each other. Teachers did not provide opportunities for students to discuss

    The current paper draws on data generated through group interviews with students who were involved in a larger ethnographic research project performed in three science classrooms. The purpose of the study from which this data was generated, was to understand science teachers' assessment practices in an upper-secondary school in Sweden. During group interviews students were asked about their conceptions of what were the assessment priority of teachers, why the students were silent during lecturing and their experiences regarding peer- and self-assessments. The research design and analysis of the findings derives from what students told us about their assessments and learning sciences experiences. Students related that besides the results of the written test, they do not know what else teachers assessed and used to determine their grades. It was also found that students did not participate in the discussion on science because of peer-pressure and a fear of disappointing their peers. Student silence is also linked with student conceptions of science learning and student experiences with methodologies of teaching and learning sciences.

  5. Science teachers' mission impossible?: a qualitative study of obstacles in assessing students' practical abilities

    Science teachers regard practical work as important and many claim that it helps students to learn science. Besides theoretical knowledge, such as concepts and formulas, practical work is considered to be an integral and basic part of science education. As practical work is perceived and understood in different ways, comparing the results between classes and schools is difficult. One way of making the results comparable is to develop systematic inquiries to be assessed in national large-scale tests. However, introducing similar testing conditions in a laboratory environment is not always possible. Although the instructions and assessment guides for such tests are detailed, many obstacles need to be overcome if equality in the overall test situation is to be achieved. This empirical case study investigates two secondary school science teachers' assessments of 15-16 years old students in three separate groups in the practical part of a Swedish national test in chemistry. Data are gathered using two video cameras and three pairs of spy camera glasses. The results show that individual and independent assessments are difficult due to the social interactions that take place and the physical sources of errors that occur in this type of setting.

    Genc, Evrim

    The primary purpose of this study was to develop a valid and reliable instrument to examine science teachers' assessment beliefs and practices in science classrooms. The present study also investigated the relationship between teachers' beliefs and practices in terms of assessment issues in science, their perceptions of the factors that influenced their assessment practices and their feelings towards high-stakes testing. The participants of the study were 408 science teachers teaching at middle and high school levels in the State of Florida. Data were collected through two modes of administration of the instrument as a paper-and-pencil and a web-based form. The response rate for paper-and-pencil administration was estimated as 68% whereas the response for the web administration was found to be 27%. Results from the various dimensions of validity and reliability analyses revealed that the 24 item-four-factor belief and practice measures were psychometrically sound and conceptually anchored measures of science teachers' assessment beliefs and self-reported practices. Reliability estimates for the belief measure ranged from .83 to .91 whereas alpha values for the practice measure ranged from .56 to .90. Results from the multigroup analysis supported that the instrument has the same theoretical structure across both administration groups. Therefore, future researchers may use either a paper-and-pencil or web-based format of the instrument. This study underscored a discrepancy between what teachers believe and how they act in classroom settings. It was emphasized that certain factors were mediating the dynamics between the belief and the practice. The majority of teachers reported that instruction time, class size, professional development activities, availability of school funding, and state testing mandates impact their assessment routines. Teachers reported that both the preparation process and the results of the test created unbelievable tension both on students and

  8. Teacher Quality Indicators as Predictors of Instructional Assessment Practices in Science Classrooms in Secondary Schools in Barbados

    This study investigated the self-reported instructional assessment practices of a selected sample of secondary school science teachers in Barbados. The study sought to determine if there were statistically significant differences in the instructional assessment practices of teachers based on their sex and teacher quality (teaching experience, professional qualification and teacher academic qualification). It also sought to determine the extent to which each of these four selected variables individually and jointly affected the teachers' report of their instructional assessment practices. A sample of 55 science teachers from nine secondary schools in Barbados was randomly selected to participate in this study. Data was collected by means of a survey and was analyzed using the means and standard deviations of the instructional assessment practices scores and linear, multiple and binary logistic regression. The results of the study were such that the majority of the sample reported good overall instructional assessment practices while only a few participants reported moderate assessment practices. The instructional assessment practices in the area of student knowledge were mostly moderate as indicated by the sample. There were no statistically significant differences between or among the mean scores of the teachers' reported instructional assessment practices based on sex ( t = 0.10; df = 53; p = 0.992), teaching experience ( F[4,50] = 1.766; p = 0.150), the level of professional qualification (F[3,45] = 0.2117; p = 0.111) or the level of academic qualification (F[2,52] = 0.504; p = 0.607). The independent variables (teacher sex, teaching experience, teacher professional qualification or teacher academic qualification) were not significant predictors of the instructional assessment practices scores. However, teacher sex was a significant predictor of the teachers' report of good instructional assessment practices. The study also found that the joint effect of the

    Major changes are currently afoot as to how practical work will be assessed in high status examinations (GCSEs for 16 year-olds and ‘A’ levels for 18 year-olds) in England. We explore here how practical skills might best be assessed in school science and introduce two terms: direct assessment of practical skills (DAPS) and indirect assessment of practical skills (IAPS). We conclude that both the direct and indirect assessment of practical skills have their place in effective assessment of sch...

    An important purpose of formative assessment is to elicit student thinking to use in instruction to help all students learn and inform next steps in teaching. However, formative assessment practices are difficult to implement and thus present a formidable challenge for many science teachers. A critical need in geoscience education is a framework for providing teachers with real-time assessment tools as well as professional development to learn how to use formative assessment to improve instruction. Here, we describe a comprehensive support system, developed for our NSF-funded Contingent Pedagogies project, for addressing the challenge of helping teachers to use formative assessment to enhance student learning in middle school Earth Systems science. Our support system is designed to improve student understanding about the geosphere by integrating classroom network technology, interactive formative assessments, and contingent curricular activities to guide teachers from formative assessment to instructional decision-making and improved student learning. To accomplish this, we are using a new classroom network technology, Group Scribbles, in the context of an innovative middle-grades Earth Science curriculum called Investigating Earth Systems (IES). Group Scribbles, developed at SRI International, is a collaborative software tool that allows individual students to compose “scribbles” (i.e., drawings and notes), on “post-it” notes in a private workspace (a notebook computer) in response to a public task. They can post these notes anonymously to a shared, public workspace (a teacher-controlled large screen monitor) that becomes the centerpiece of group and class discussion. To help teachers implement formative assessment practices, we have introduced a key resource, called a teaching routine, to help teachers take advantage of Group Scribbles for more interactive assessments. Routine refers to a sequence of repeatable interactions that, over time, become

    2001-07-01

    Classroom assessment practices of middle school science teachers were identified and the influence of national and state science standards on these practices was examined. In Phase I of this study a mail questionnaire was sent to 450 middle school (grades 5,6,7 and 8) science teachers in 17 parishes in Louisiana to obtain information about their classroom assessment practices. In Phase II, nine middle school teachers in eight departmentalized classrooms, two classes at each grade, participated in a qualitative study. Data were collected through questionnaires, classroom observations, interviews and document analysis. Data analysis revealed three major categories of classroom assessment targets: (a) student achievement, (b) student attitudes and, (c) student products. Results indicated that most teachers are using different assessment methods when assessing different achievement targets, as recommended by science reform documents. It was also determined that many teachers are using appropriate methods to assess student learning. While teachers reported that students spend an inordinate amount of time engaged in assessment activities, classroom observations suggested that the activities were not always written tests or graded activities. Another key finding is that there is a disconnect between the quality of teaching and the quality of assessment. Teachers who teach the material recommended by science reform documents and use recommended instructional strategies were observed to stop teaching and engage students in a "test rehearsal" geared towards rote memorization of factual information. Data suggest that the national and state science content standards are influencing the content and the format of teacher-made tests. Teachers' reported using the standards during assessment construction or selection in a wide variety of ways. The most direct use of the standards reported was to select content, format and cognitive level for test items. A more circumspect approach

  13. Assessing Dimensions of Inquiry Practice by Middle School Science Teachers Engaged in a Professional Development Program

    Lakin, Joni M.; Wallace, Carolyn S.

    2015-03-01

    Inquiry-based teaching promotes students' engagement in problem-solving and investigation as they learn science concepts. Current practice in science teacher education promotes the use of inquiry in the teaching of science. However, the literature suggests that many science teachers hold incomplete or incorrect conceptions of inquiry. Teachers, therefore, may believe they are providing more inquiry experiences than they are, reducing the positive impact of inquiry on science interest and skills. Given the prominence of inquiry in professional development experiences, educational evaluators need strong tools to detect intended use in the classroom. The current study focuses on the validity of assessments developed for evaluating teachers' use of inquiry strategies and classroom orientations. We explored the relationships between self-reported inquiry strategy use, preferences for inquiry, knowledge of inquiry practices, and related pedagogical content knowledge. Finally, we contrasted students' and teachers' reports of the levels of inquiry-based teaching in the classroom. Self-reports of inquiry use, especially one specific to the 5E instructional model, were useful, but should be interpreted with caution. Teachers tended to self-report higher levels of inquiry strategy use than their students perceived. Further, there were no significant correlations between either knowledge of inquiry practices or PCK and self-reported inquiry strategy use.

  14. Reshaping teacher thinking, planning and practice using embedded assessment: Case studies of three middle school science teachers

    Jeranyama, Letina Ngwenya

    At the dawn of the 21st century the science education community is seeking ways of improving science education to produce a scientific literate citizenry. They have put forth new goals. Teachers are key to all efforts to improve schools, that without their full participation, any move to reform education nor matter how well intentioned is doomed to failure. The changes in the goals of science education imply that teachers have to change the way they teach science. Some scholars have suggested that one way to help teachers attain the reform goals is by using embedded assessment. Embedded assessment is defined as a cyclical and ongoing process whereby teachers gather data about students' understanding as they teach, they analyze the data formally or informally and use the analysis to plan or adjust teaching immediately, for the next hour, day, topic, unit or year. The next day's activities also include embedded assessment and so the cycle repeats itself. This study investigates how teachers make sense of embedded assessment, how embedded assessment looks in practice, how it influences teachers and their classroom environments and the challenges teachers face as they use embedded assessment. Three middle school science teachers were involved in the study. Data were collected through semi-structured interviews with open-ended questions, participant observations and professional development conversations. Data were analyzed using the qualitative method of constant comparative analysis. The findings indicate that teachers passed through different stages in conceptualizing embedded assessment. This conceptualization influenced the way embedded assessment looked in the classroom. Embedded assessment took many forms and shapes in the teachers' classrooms. Embedded assessment influenced the teachers' perspectives about the curriculum, students, teaching, assessment, planning and reflection in ways that enabled the teachers to be investigators of their students' understanding

  15. Psychometrics in action, science as practice.

    2017-07-27

    Practitioners in health sciences education and assessment regularly use a range of psychometric techniques to analyse data, evaluate models, and make crucial progression decisions regarding student learning. However, a recent editorial entitled "Is Psychometrics Science?" highlighted some core epistemological and practical problems in psychometrics, and brought its legitimacy into question. This paper attempts to address these issues by applying some key ideas from history and philosophy of science (HPS) discourse. I present some of the conceptual developments in HPS that have bearing on the psychometrics debate. Next, by shifting the focus onto what constitutes the practice of science, I discuss psychometrics in action. Some incorrectly conceptualize science as an assemblage of truths, rather than an assemblage of tools and goals. Psychometrics, however, seems to be an assemblage of methods and techniques. Psychometrics in action represents a range of practices using specific tools in specific contexts. This does not render the practice of psychometrics meaningless or futile. Engaging in debates about whether or not we should regard psychometrics as 'scientific' is, however, a fruitless enterprise. The key question and focus should be whether, on what grounds, and in what contexts, the existing methods and techniques used by psychometricians can be justified or criticized.

    2004-02-01

    School-based assessment of science students' practical skills has two important roles--as a complement to written papers in public examinations and as a catalyst for enriching the science curriculum in schools. This article describes a quantitative study of the concerns chemistry and biology teachers experience as they engage in the process of implementation of a school-based assessment scheme for practical work. A 23-item questionnaire was developed to measure five categories of teacher concern: evaluation, information, management, consequence and refocusing. The nature of each category of teacher concern is discussed in relation to innovation adoption and implementation. Data were collected from 400 chemistry and 412 biology teachers in Hong Kong. Teachers' information and management concerns lessened in intensity when they became experienced users of a school-based assessment scheme. However, teaching experience alone could not motivate teachers to think more about the impact of school-based assessment on student learning, their professional development in student assessment and the possible refinements in their school-based assessment scheme. Concerns-based interventions are suggested to help teachers grow professionally.

  19. Evidence of system: A network model case-study of seventh grade science assessment practices from classrooms to the state test

    Piety, Philip John

    With science education in the United States entering a period of greater accountability, this study investigated how student learning in science was assessed by educators within one state, asking what systemic assessment approaches existed and how the information from them was used. Conducted during the 20o6-2007 school year, this research developed and piloted a network-model case study design that included teachers, principals, administrators, and the state test development process, as well as several state-level professional associations. The data analyzed included observations, interviews, surveys, and both public and private documents. Some data were secondary. This design produced an empirical depiction of practice with a web of related cases. The network model expands on the hierarchical (nested) models often assumed in the growing literature on how information is used in educational contexts by showing multiple ways in which individuals are related through organizational structures. Seven case study teachers, each employing assessment methods largely unique and invisible to others in their schools, illustrate one set of assessment practices. The only alternative to classroom assessments that could be documented was the annual state accountability test. These two assessment species were neither tightly coupled nor distinct. Some teachers were partners in developing state test instruments, and in some cases the annual test could be seen as a school management resource. Boundary practices---activities where these two systems connected---were opportunities to identify challenges to policy implementation in science education. The challenges include standards, cognition, vocabulary, and classroom equipment. The boundary practices, along with the web of connections, provide the outlines of potential (and often unrealized) synergistic relationships. This model shows diverse indigenous practices and adaptations by actors responding to pressures of change and

    2016-12-01

    Full Text Available Shifting from teacher-centred to student-centred practices requires teachers to understand strategies to interact with students in science classes. Formative assessment strategies are very critical component of classroom interaction where teachers obtain information about student learning wherever possible. Traditionally, however, teachers ask questions and evaluate student responses but without investigating student contributions to the classroom interaction. This qualitative study aimed at developing teachers’ knowledge of formative assessment strategies when teaching science-based inquiry in Saudi Arabia. 12 teachers were observed when teaching science and details of one teachers’ practices of formative assessment is presented in this study. Formative assessment framework that describes assessment conversations is used and modified to observe teachers’ assessment practices. Assessment conversation consists of four-step cycles, where the teacher elicits information from students through questioning, the student responds, the teacher recognizes the student’s response, and then uses the information to develop further inquiry. Findings indicate that teachers ask questions and receive responses but rarely allow students to share their own ideas or discuss their own thinking. The study underlines the importance of integrating formative assessment strategies during scientific inquiry teaching for professional development as a way to increase student participation and allow opportunities for students’ inquiry in science classes.

    2017-12-01

    The FitnessGram® program has provided teachers with practical tools to enhance physical education programming. A key to the success of the program has been the systematic application of science to practice. Strong research methods have been used to develop assessments and standards for use in physical education, but consideration has also been given to ensure that programming meets the needs of teachers, students, parents, and other stakeholders. This essay summarizes some of these complex and nuanced intersections between science and practice with the FitnessGram® program. The commentaries are organized into 5 brief themes: science informing practice; practice informing science; balancing science and practice; promoting evidence-based practice; and the integration of science and practice. The article draws on personal experiences with the FitnessGram® program and is prepared based on comments shared during the 37th Annual C. H. McCloy Research Lecture at the 2017 SHAPE America - Society of Health and Physical Educators Convention.

    2006-06-01

    As sports scientists, we claim to make a significant contribution to the body of knowledge that influences athletic practice and performance. Is this the reality? At the inaugural congress of the Australian Association for Exercise and Sports Science, a panel of well-credentialed academic experts with experience in the applied environment debated the question, Does sports-science research influence practice? The first task was to define "sports-science research," and it was generally agreed that it is concerned with providing evidence that improves sports performance. When practices are equally effective, sports scientists also have a role in identifying practices that are safer, more time efficient, and more enjoyable. There were varying views on the need for sports-science research to be immediately relevant to coaches or athletes. Most agreed on the importance of communicating the results of sports-science research, not only to the academic community but also to coaches and athletes, and the need to encourage both short- and long-term research. The panelists then listed examples of sports-science research that they believe have influenced practice, as well as strategies to ensure that sports-science research better influences practice.

  6. Promoting Prospective Elementary Teachers' Learning to Use Formative Assessment for Life Science Instruction

    Sabel, Jaime L.; Forbes, Cory T.; Zangori, Laura

    2015-06-01

    To support elementary students' learning of core, standards-based life science concepts highlighted in the Next Generation Science Standards, prospective elementary teachers should develop an understanding of life science concepts and learn to apply their content knowledge in instructional practice to craft elementary science learning environments grounded in students' thinking. To do so, teachers must learn to use high-leverage instructional practices, such as formative assessment, to engage students in scientific practices and connect instruction to students' ideas. However, teachers may not understand formative assessment or possess sufficient science content knowledge to effectively engage in related instructional practices. To address these needs, we developed and conducted research within an innovative course for preservice elementary teachers built upon two pillars—life science concepts and formative assessment. An embedded mixed methods study was used to evaluate the effect of the intervention on preservice teachers' (n = 49) content knowledge and ability to engage in formative assessment practices for science. Findings showed that increased life content knowledge over the semester helped preservice teachers engage more productively in anticipating and evaluating students' ideas, but not in identifying effective instructional strategies to respond to those ideas.

  9. Dilemmas of reform: An exploration of science teachers' collective sensemaking of formative assessment practices

    Science.gov (United States)

    Heredia, Sara Catherine

    Current reform efforts in science education call for significant shifts in how science is taught and learned. Teachers are important gatekeepers for reform, as they must enact these changes with students in their own classrooms. As such, professional development approaches need to be developed and studied to understand how teachers interpret and make instructional plans to implement these reforms. However, traditional approaches to studying implementation of reforms often draw on metrics such as time allotted to new activities, rather than exploring the ways in which teachers make sense of these reforms. In this dissertation I draw upon a body of work called sensemaking that has focused on locating learning in teachers' conversations in departmental work groups. I developed a conceptual and analytic framework to analyze how teachers make sense of reform given their local contexts and then used this framework to perform a case study of one group of teachers that participated in larger professional development project that examined the impact of a learning progression on science teachers' formative assessment practices. I draw upon videotapes of three years of monthly professional development meetings as my primary source of data, and used an ethnographic approach to identify dilemmas surfaced by teachers, sources of ambiguity and uncertainty, and patterns of and resources for teacher sensemaking. The case study reveals relationships between the type of dilemma surfaced by the teachers and different patterns of sensemaking for modification of teaching practices. When teachers expressed concerns about district or administrative requirements, they aligned their work in the professional development to those external forces. In contrast, teachers were able to develop and try out new practices when they perceived coherence between the professional development and school or district initiatives. These results underscore the importance of coherence between various

  10. Towards Building Science Teachers’ Understandings of Contemporary Science Practices

    Directory of Open Access Journals (Sweden)

    Greg Lancaster

    2017-03-01

    Full Text Available Faculties of Education and Science at Monash University have designed a Masters unit to assist pre-service and in-service science teachers in exploring the practices of contemporary science and examine how varied understandings can influence science communication. Teachers are encouraged to explore their current understandings of the Nature of Science (NoS and to contrast their views with those known to be widely held by society (Cobern & Loving, 1998. Teachers are challenged to provide insights into their thinking relating to the NoS. In order to build understandings of contemporary science practice each teacher shadows a research scientist and engages them in conversations intended to explore the scientists’ views of NoS and practice. Findings suggest that teachers were initially uncomfortable with the challenge to express ideas relating to their NoS and were also surprised how diverse the views of NoS can be among teachers, scientists and their peers, and that these views can directly impact ways of communicating contemporary science practice.

    Contemporary assessment practices in science education have undergone significant changes in recent decades. The basis for these changes and the resulting new assessment practices are the subject of this two-part paper. Part 1 considers the basis of assessment that, more than 25 years ago, was driven by the assumptions of decomposability and decontextualization of knowledge, resulting in a low-inference testing system, often described as traditional. This assessment model was replaced not on account of direct criticism, but rather on account of a larger revolution - the change from behavioral to cognitive psychology, developments in the philosophy of science, and the rise of constructivism. Most notably, the study of the active cognitive processes of the individual resulted in a major emphasis on context in learning and assessment. These changes gave rise to the development of various contextual assessment methodologies in science education, for example, concept mapping assessment, performance assessment, and portfolio assessment. In Part 2, the literature relating to the assessment methods identified in Part 1 is reviewed, revealing that there is not much research that supports their validity and reliability. However, encouraging new work on selected-response tests is forming the basis for reconsideration of past criticisms of this technique. Despite the major developments in contextual assessment methodologies in science education, two important questions remain unanswered, namely, whether grades can be considered as genuine numeric quantities and whether the individual student is the appropriate unit of assessment in public accountability. Given these issues and the requirement for science assessment to satisfy the goals of the individual, the classroom, and the society, tentative recommendations are put forward addressing these parallel needs in the assessment of science learning.

    Progress monitoring is a type of formative assessment. Most work on progress monitoring in elementary school settings has been focused on students. However, teachers also can benefit from frequent evaluations. Research addressing teacher progress monitoring is critically important given the recent national focus on teacher evaluation and effectiveness. This special topic section of School Psychology Quarterly is the first to showcase the current research on measuring Tier 1 instructional and behavioral management practices used by prekindergarten and elementary school teachers in general education settings. The three studies included in the special section describe the development and validation efforts of several teacher observational and self-report measures of instruction and/or behavioral management. These studies provide evidence for the utility of such assessments for documenting the use of classroom practices, and these assessment results may be leveraged in innovative coaching models to promote best practice. These articles also offer insight and ideas for the next generation of teacher practice assessment for the field. Finally, the special topic is capped by a commentary synthesizing the current work and offers "big ideas" for future measurement development, policy, and professional development initiatives.

    MyScience is a primary science education initiative in which being in a community of practice is integral to the learning process. In this initiative, stakeholder groups—primary teachers, primary students and mentors—interact around the `domain' of `investigating scientifically'. This paper builds on three earlier publications and interprets the findings of the views of four secondary science teachers and five year 9 secondary science students who were first-timer participants—as mentors—in MyScience. Perceptions of these mentors' interactions with primary students were analysed using attributes associated with both `communities of practice' and the `nature of science'. Findings reveal that participation in MyScience changed secondary science teachers' views and practices about how to approach the teaching of science in secondary school and fostered primary-secondary links. Year 9 students positively changed their views about secondary school science and confidence in science through participation as mentors. Implications for secondary science teaching and learning through participation in primary school community of science practice settings are discussed.

    Many calls to improve science education in college and university settings have focused on improving instructor pedagogy. Meanwhile, science education at the K-12 level is undergoing significant changes as a result of the emphasis on scientific and engineering practices, crosscutting concepts, and disciplinary core ideas. This framework of “three-dimensional learning” is based on the literature about how people learn science and how we can help students put their knowledge to use. Recently, similar changes are underway in higher education by incorporating three-dimensional learning into college science courses. As these transformations move forward, it will become important to assess three-dimensional learning both to align assessments with the learning environment, and to assess the extent of the transformations. In this paper we introduce the Three-Dimensional Learning Assessment Protocol (3D-LAP), which is designed to characterize and support the development of assessment tasks in biology, chemistry, and physics that align with transformation efforts. We describe the development process used by our interdisciplinary team, discuss the validity and reliability of the protocol, and provide evidence that the protocol can distinguish between assessments that have the potential to elicit evidence of three-dimensional learning and those that do not.

  19. Making Philosophy of Science Education Practical for Science Teachers

    Philosophy of science education can play a vital role in the preparation and professional development of science teachers. In order to fulfill this role a philosophy of science education should be made practical for teachers. First, multiple and inherently incomplete philosophies on the teacher and teaching on what, how and why should be integrated. In this paper we describe our philosophy of science education (ASSET approach) which is composed of bounded rationalism as a guideline for understanding teachers' practical reasoning, liberal education underlying the why of teaching, scientific perspectivism as guideline for the what and educational social constructivism as guiding choices about the how of science education. Integration of multiple philosophies into a coherent philosophy of science education is necessary but not sufficient to make it practical for teachers. Philosophies are still formulated at a too abstract level to guide teachers' practical reasoning. For this purpose, a heuristic model must be developed on an intermediate level of abstraction that will provide teachers with a bridge between these abstract ideas and their specific teaching situation. We have developed and validated such a heuristic model, the CLASS model in order to complement our ASSET approach. We illustrate how science teachers use the ASSET approach and the CLASS model to make choices about the what, the how and the why of science teaching.

  20. How does a Next Generation Science Standard Aligned, Inquiry Based, Science Unit Impact Student Achievement of Science Practices and Student Science Efficacy in an Elementary Classroom?

    Whittington, Kayla Lee

    This study examined the impact of an inquiry based Next Generation Science Standard aligned science unit on elementary students' understanding and application of the eight Science and Engineering Practices and their relation in building student problem solving skills. The study involved 44 second grade students and three participating classroom teachers. The treatment consisted of a school district developed Second Grade Earth Science unit: What is happening to our playground? that was taught at the beginning of the school year. Quantitative results from a Likert type scale pre and post survey and from student content knowledge assessments showed growth in student belief of their own abilities in the science classroom. Qualitative data gathered from student observations and interviews performed at the conclusion of the Earth Science unit further show gains in student understanding and attitudes. This study adds to the existing literature on the importance of standard aligned, inquiry based science curriculum that provides time for students to engage in science practices.

  1. Practicing the practice: Learning to guide elementary science discussions in a practice-oriented science methods course

    Science.gov (United States)

    Shah, Ashima Mathur

    University methods courses are often criticized for telling pre-service teachers, or interns, about the theories behind teaching instead of preparing them to actually enact teaching. Shifting teacher education to be more "practice-oriented," or to focus more explicitly on the work of teaching, is a current trend for re-designing the way we prepare teachers. This dissertation addresses the current need for research that unpacks the shift to more practice-oriented approaches by studying the content and pedagogical approaches in a practice-oriented, masters-level elementary science methods course (n=42 interns). The course focused on preparing interns to guide science classroom discussions. Qualitative data, such as video records of course activities and interns' written reflections, were collected across eight course sessions. Codes were applied at the sentence and paragraph level and then grouped into themes. Five content themes were identified: foregrounding student ideas and questions, steering discussion toward intended learning goals, supporting students to do the cognitive work, enacting teacher role of facilitator, and creating a classroom culture for science discussions. Three pedagogical approach themes were identified. First, the teacher educators created images of science discussions by modeling and showing videos of this practice. They also provided focused teaching experiences by helping interns practice the interactive aspects of teaching both in the methods classroom and with smaller groups of elementary students in schools. Finally, they structured the planning and debriefing phases of teaching so interns could learn from their teaching experiences and prepare well for future experiences. The findings were analyzed through the lens of Grossman and colleagues' framework for teaching practice (2009) to reveal how the pedagogical approaches decomposed, represented, and approximated practice throughout course activities. Also, the teacher educators

    Embedded in community science are implicit theories on the nature of reality (ontology), the justification of knowledge claims (epistemology), and how knowledge is constructed (methodology). These implicit theories influence the conceptualization and practice of research, and open up or constrain its possibilities. The purpose of this paper is to make some of these theories explicit, trace their intellectual history, and propose a shift in the way research in the social and behavioral sciences, and community science in particular, is conceptualized and practiced. After describing the influence and decline of logical empiricism, the underlying philosophical framework for science for the past century, I summarize contemporary views in the philosophy of science that are alternatives to logical empiricism. These include contextualism, normative naturalism, and scientific realism, and propose that a modified version of contextualism, known as perspectivism, affords the philosophical framework for an emerging community science. I then discuss the implications of perspectivism for community science in the form of four propositions to guide the practice of research.

  3. Elementary teachers' knowledge and practices in teaching science to English language learners

    Santau, Alexandra O.

    Efforts to improve education---more concretely science education---by creating fundamental shifts in standards for students and teachers have been launched by educators and policy makers in recent years. The new standards for science instruction address improvements in student learning, program development, assessment, and professional development for teachers, with the goal to prepare US students for the academic demands of the 21st century. The study examined teachers' knowledge and practices in science instruction with English language learning (ELL) students. It also examined relationships among key domains of science instruction with ELL students, as well as profiles of teaching practices. The four domains included: (1) teachers' knowledge of science content, (2) teaching practices to promote scientific understanding, (3) teaching practices to promote scientific inquiry, and (4) teaching practices to support English language development during science instruction. The study was part of a larger 5-year research and development intervention aimed at promoting science and literacy achievement of ELL students in urban elementary schools. The study involved 32 third grade, 21 fourth grade, and 17 fifth grade teachers participating in the first-year implementation of the intervention. Based on teachers' questionnaire responses, classroom observation ratings, and post-observation interviews, results indicated that (1) teachers' knowledge and practices were within the bounds of the intervention, but short of reform-oriented practices and (2) relationships among the four domains existed, especially at grade 5. These findings can provide insights for professional development and future research, along with accountability policies.

    Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students' spoken or written argumentation. Consequently, teachers' pedagogical practices regarding argumentation gain importance due to their impact on how they incorporate this practice into their classrooms. In this study, therefore, we investigated the instructional strategies adopted by science teachers for their argumentation-based science teaching. Participants were one elementary science teacher, two chemistry teachers, and four graduate students, who have a background in science education. The study took place during a graduate course, which was aimed at developing science teachers' theory and pedagogy of argumentation. Data sources included the participants' video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants' written materials. The findings revealed three typologies of instructional strategies towards argumentation. They are named as Basic Instructional Strategies for Argumentation, Meta-level Instructional ‌St‌‌rategies for ‌Argumentation, and Meta-strategic Instructional ‌St‌‌rategies for ‌Argumentation. In conclusion, the study provided a detailed coding framework for the exploration of science teachers' instructional practices while they are implementing argumentation-based lessons.

    This study examined the perceptions and self-reported practices of 18 scientists participating in a yearlong seminar series designed to explore issues of gender and ethnicity in science. Scientists and seminar were part of the Promoting Women and Scientific Literacy project, a curriculum transformation and professional development initiative undertaken by science, science education, and women's studies faculty at their university. Researchers treated participating scientists as critical friends able to bring clarity to and raise questions about conceptions of inclusion in science education. Through questionnaires and semistructured interviews, we explored their (a) rationales for differential student success in undergraduate science education; (b) self-reports of ways they structure, teach, and assess courses to promote inclusion; and (c) views of androcentric and ethnocentric bias in science. Statistical analysis of questionnaires yielded few differences in scientists' views and reported practices by sex or across time. Qualitative analysis of interviews offered insight into how scientists can help address the problem of women and ethnic minorities in science education; constraints encountered in attempts to implement pedagogical and curricular innovations; and areas of consensus and debate across scientists and science studies scholars' descriptions of science. From our findings, we provided recommendations for other professional developers working with scientists to promote excellence and equity in undergraduate science education.

    Four high school Biology teachers, two novice and two experienced, participated in a year and a half case study. By utilizing a naturalistic paradigm, the four individuals were studied in their natural environment, their classrooms. Data sources included: three semi-structured interviews, classroom observation field notes, and classroom artifacts. Through cross-case analysis and a constant comparative methodology, coding nodes where combined and refined resulting in the final themes for discussion. The following research question was investigated: what is the impact of high-stakes testing on high school Biology teacher's instructional planning, instructional practices and classroom assessments? Seven final themes were realized: Assessment, CSAP, Planning, Pressure, Standards, Teaching and Time. Each theme was developed and discussed utilizing each participant's voice. Trustworthiness of this study was established via five avenues: triangulation of data sources, credibility, transferability, dependability and confirmability. A model of the influences of high-stakes testing on teacher practice was developed to describe the seven themes (Figure 5). This model serves as an illustration of the complex nature of teacher practice and the influences upon it. The four participants in this study were influenced by high-stakes assessment. It influenced their instructional decisions, assessment practices, use of time, planning decisions and decreased the amount of inquiry that occurred in the classroom. Implications of this research and future research directions are described.

    The Teacher Assessment in Primary Science project is funded by the Primary Science Teaching Trust and based at Bath Spa University. The study aims to develop a whole-school model of valid, reliable and manageable teacher assessment to inform practice and make a positive impact on primary-aged children's learning in science. The model is based on a data-flow 'pyramid' (analogous to the flow of energy through an ecosystem), whereby the rich formative assessment evidence gathered in the classroom is summarised for monitoring, reporting and evaluation purposes [Nuffield Foundation. (2012). Developing policy, principles and practice in primary school science assessment. London: Nuffield Foundation]. Using a design-based research (DBR) methodology, the authors worked in collaboration with teachers from project schools and other expert groups to refine, elaborate, validate and operationalise the data-flow 'pyramid' model, resulting in the development of a whole-school self-evaluation tool. In this paper, we argue that a DBR approach to theory-building and school improvement drawing upon teacher expertise has led to the identification, adaptation and successful scaling up of a promising approach to school self-evaluation in relation to assessment in science.

  10. An exploration of middle school science teachers' understandings and teaching practice of science as inquiry

    Castle, Margaret Ann

    A number of reports have raised a concern that the U.S. is not meeting the demands of 21st century skill preparation of students, teachers, and practitioners in the areas of science, technology, engineering, and mathematics (STEM). In 2005 and 2006 five reports were released indicating a need for improvement in science and mathematics education in the U.S. The reports were: Keeping America Competitive: Five Strategies To Improve Mathematics and Science Education (Coble & Allen, 2005); National Defense Education and Innovation Initiative: Meeting America's Economic and Security Challenges in the 21st Century (The Association of American Universities, 2006); Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future (National Academies Press, 2007); Tapping America's Potential: The Education for Innovation Initiative (Business Roundtable Taskforce , 2005); and Waiting for Sputnik: Basic Research and Strategic Competition (Lewis, 2005). Consensus of data in these reports indicates that the U.S., as compared to other industrialized nations, does not fare very well in science achievement and STEM degree attainment. For example, on the 2003 Program for International Assessment (PISA), 15-year-old students in the U.S. ranked 28th in math and 24th in science literacy (Kuenzi, Matthews, & Mangon, 2006). Furthermore, the U.S. ranked 20th among all nations in the proportion of 24-year-olds who earned degrees in natural sciences or engineering (Kuenzi, 2008). As a result, if the U.S. is to remain scientifically and technologically competitive in the world, it is necessary to increase our efforts to incorporate scientific practices associated with science, technology, engineering, and mathematics into the science classroom. Middle school is a critical point in students' science education and it is in middle school that they begin to dislike science. Research indicates that when students learn science through inquiry their interest in and

    The USGS has a long and proud tradition of objective, unbiased science in service to the Nation. A reputation for impartiality and excellence is one of our most important assets. To help preserve this vital asset, in 2004 the Executive Leadership Team (ELT) of the USGS was charged by the Director to develop a set of fundamental science practices, philosophical premises, and operational principles as the foundation for all USGS research and monitoring activities. In a concept document, 'Fundamental Science Practices of the U.S. Geological Survey', the ELT proposed 'a set of fundamental principles to underlie USGS science practices.' The document noted that protecting the reputation of USGS science for quality and objectivity requires the following key elements: - Clearly articulated, Bureau-wide fundamental science practices. - A shared understanding at all levels of the organization that the health and future of the USGS depend on following these practices. - The investment of budget, time, and people to ensure that the USGS reputation and high-quality standards are maintained. The USGS Fundamental Science Practices (FSP) encompass all elements of research investigations, including data collection, experimentation, analysis, writing results, peer review, management review, and Bureau approval and publication of information products. The focus of FSP is on how science is carried out and how products are produced and disseminated. FSP is not designed to address the question of what work the USGS should do; that is addressed in USGS science planning handbooks and other documents. Building from longstanding existing USGS policies and the ELT concept document, in May 2006, FSP policies were developed with input from all parts of the organization and were subsequently incorporated into the Bureau's Survey Manual. In developing an implementation plan for FSP policy, the intent was to recognize and incorporate the best of USGS current practices to obtain the optimum

    2002-05-01

    Calls for reform have suggested that classroom practice can best be changed by teachers who engage in their own research. This interpretive study examines the process of action research and how it contributes to the professional development of a first-grade teacher. The purpose of the study was to explore the research process experienced by the teacher as she examined whether portfolios could be used as an effective means for facilitating and assessing young children's development of science process skills. Data sources included a journal kept by the teacher, documents produced by the teacher and students as part of the portfolio implementation process, hand-written records of teacher's informal interviews with students, and anecdotal records from research team meetings during the study. Data analysis was designed to explore how the teacher's classroom practices and thinking evolved as she engaged in action research and attempted to solve the problems associated with deciding what to assess and how to implement portfolio assessment. We also examined the factors that supported the teacher's learning and change as she progressed through the research process. Data are presented in the form of four assertions that clarify how the action research process was influenced by various personal and contextual factors. Implications address factors that facilitated the teacher as researcher, and how this research project, initiated by the teacher, affected her professional development and professional life.

    Grounded in Hallidayan perspectives on academic language, we report on our development of an educative science assessment as one component of the language-rich inquiry science for English-language learners teacher professional learning project for middle school science teachers. The project emphasizes the role of content-area writing to support teachers in diagnosing their students' emergent understandings of science inquiry practices, science content knowledge, and the academic language of science, with a particular focus on the needs of English-language learners. In our current school policy context, writing for meaningful purposes has received decreased attention as teachers struggle to cover large numbers of discrete content standards. Additionally, high-stakes assessments presented in multiple-choice format have become the definitive measure of student science learning, further de-emphasizing the value of academic writing for developing and expressing understanding. To counter these trends, we examine the implementation of educative assessment materials—writing-rich assessments designed to support teachers' instructional decision making. We report on the qualities of our educative assessment that supported teachers in diagnosing their students' emergent understandings, and how teacher-researcher collaborative scoring sessions and interpretation of assessment results led to changes in teachers' instructional decision making to better support students in expressing their scientific understandings. We conclude with implications of this work for theory, research, and practice.

    The aims of this study were to (i) assess the expectations of general practice departments regarding health sciences libraries' subscriptions to journals and (ii) describe the current general practice journal collections of health sciences libraries. A cross-sectional survey was distributed electronically to the thirty-five university general practice departments in France. General practice departments were asked to list ten journals to which they expected access via the subscriptions of their health sciences libraries. A ranked reference list of journals was then developed. Access to these journals was assessed through a survey sent to all health sciences libraries in France. Adequacy ratios (access/need) were calculated for each journal. All general practice departments completed the survey. The total reference list included 44 journals. This list was heterogeneous in terms of indexation/impact factor, language of publication, and scope (e.g., patient care, research, or medical education). Among the first 10 journals listed, La Revue Prescrire (96.6%), La Revue du Praticien-Médecine Générale (90.9%), the British Medical Journal (85.0%), Pédagogie Médicale (70.0%), Exercer (69.7%), and the Cochrane Database of Systematic Reviews (62.5%) had the highest adequacy ratios, whereas Family Practice (4.2%), the British Journal of General Practice (16.7%), Médecine (29.4%), and the European Journal of General Practice (33.3%) had the lowest adequacy ratios. General practice departments have heterogeneous expectations in terms of health sciences libraries' subscriptions to journals. It is important for librarians to understand the heterogeneity of these expectations, as well as local priorities, so that journal access meets users' needs.

  18. The impact of high-stakes, state-mandated student performance assessment on 10th grade English, mathematics, and science teachers' instructional practices

    Vogler, Kenneth E.

    The purpose of this study was to determine if the public release of student results on high-stakes, state-mandated performance assessments influence instructional practices, and if so in what manner. The research focused on changes in teachers' instructional practices and factors that may have influenced such changes since the public release of high-stakes, state-mandated student performance assessment scores. The data for this study were obtained from a 54-question survey instrument given to a stratified random sample of teachers teaching at least one section of 10th grade English, mathematics, or science in an academic public high school within Massachusetts. Two hundred and fifty-seven (257) teachers, or 62% of the total sample, completed the survey instrument. An analysis of the data found that teachers are making changes in their instructional practices. The data show notable increases in the use of open-response questions, creative/critical thinking questions, problem-solving activities, use of rubrics or scoring guides, writing assignments, and inquiry/investigation. Teachers also have decreased the use of multiple-choice and true-false questions, textbook-based assignments, and lecturing. Also, the data show that teachers felt that changes made in their instructional practices were most influenced by an "interest in helping my students attain MCAS assessment scores that will allow them to graduate high school" and by an "interest in helping my school improve student (MCAS) assessment scores," Finally, mathematics teachers and teachers with 13--19 years of experience report making significantly more changes than did others. It may be interpreted from the data that the use of state-mandated student performance assessments and the high-stakes attached to this type of testing program contributed to changes in teachers' instructional practices. The changes in teachers' instructional practices have included increases in the use of instructional practices deemed

    An analyses study focusing on scientific reasoning literacy was conducted to strengthen the stressing on assessment in science by combining the important of the nature of science and assessment as references, higher order thinking and scientific skills in assessing science learning as well. Having background in developing science process skills test items, inquiry in its many form, scientific and STEM literacy, it is believed that inquiry based learning should first be implemented among science educators and science learners before STEM education can successfully be developed among science teachers, prospective teachers, and students at all levels. After studying thoroughly a number of science researchers through their works, a model of scientific reasoning was proposed, and also simple rubrics and some examples of the test items were introduced in this article. As it is only the beginning, further studies will still be needed in the future with the involvement of prospective science teachers who have interests in assessment, either on authentic assessment or in test items development. In balance usage of alternative assessment rubrics, as well as valid and reliable test items (standard) will be needed in accelerating STEM education in Indonesia.

  20. A cognitive framework to inform the design of professional development supporting teachers' classroom assessment of inquiry-based science

    Matese, Gabrielle

    Inquiry-based science places new demands on teachers for assessing students' growth, both of deep conceptual understanding as well as developing inquiry skills. In addition, new ideas about classroom assessment, such as the importance of formative assessment, are gaining currency. While we have ideas about what classroom assessment consistent with inquiry-based pedagogy might look like, and why it is necessary, we have little understanding of what it takes to implement it. That teachers face a challenge in doing so is well-documented. Researchers have noted that teachers attempting changes in classroom assessment often bring with them incompatible beliefs, knowledge, and practices. However, noting general incompatibility is insufficient to support addressing these issues through professional development. In response to this need, I initiated a research project to identify and describe in more detail the categories of beliefs, knowledge and skills that play an important role in inquiry-based science assessment practices. I created an assessment framework outlining specific categories of beliefs, knowledge, and skills affecting particular classroom assessment practices. I then used the framework to examine teachers' classroom assessment practices and to create comparative cases between three middle-school science teachers, highlighting how the different cognitive factors affect four particular assessment practices. The comparative cases demonstrate the framework's utility for analyzing and explicating teacher assessment practices. As a tool for analyzing and understanding teacher practice, the framework supports the design of professional development. To demonstrate the value of the framework, I draw on the comparative cases to identify implications for the design of professional development to support teachers' classroom assessment of inquiry-based science. In this dissertation I provide a brief overview of the framework and its rationale, present an example of the

    This descriptive study investigated the implementation practices of secondary science teachers who differentiate instruction. Participants included seven high school science teachers purposefully selected from four different schools located in a mid-Atlantic state. Purposeful selection ensured participants included differentiated instruction (DI) in their lesson implementation. Data included semi-structured interviews and field notes from a minimum of four classroom observations, selected to capture the variety of differentiation strategies employed. These data were analyzed using a constant-comparative approach. Each classroom observation was scored using the validated Differentiated Instruction Implementation Matrix-Modified, which captured both the extent to which critical indicators of DI were present in teachers' instruction and the performance levels at which they engaged in these components of DI. Results indicated participants implemented a variety of differentiation strategies in their classrooms with varying proficiency. Evidence suggested all participants used instructional modifications that required little advance preparation to accommodate differences in students' interests and learning profile. Four of the seven participants implemented more complex instructional strategies that required substantial advance preparation by the teacher. Most significantly, this study provides practical strategies for in-service science teachers beginning to differentiate instruction and recommendations for professional development and preservice science teacher education.

    This brief commentary will argue that whether hormesis is considered in regulatory risk assessment is a matter less of science than of science policy. I will first discuss the distinction between science and science policy and their roles in regulatory risk assessment. Then I will focus on factors that influence science policy, especially as it relates to the conduct of risk assessments to inform regulatory decisions, with a focus on the U.S. Environmental Protection Agency (EPA). The key questions will then be how does hormesis interact with current concepts of science and science policy for risk assessment? Finally, I look ahead to factors that may increase, or decrease, the likelihood of hormesis being incorporated into regulatory risk assessment.

    Several science education researchers have led assessment efforts that provide strategies particularly useful for evaluating the threedimensional learning that is central to NGSS (DeBarger, A. H., Penuel, W. R., Harris, C. J., Kennedy, C. K., 2016; Knight, A. M. & McNeill, K. L., 2015; McNeill, K.

One of the basic premises of these researchers is that, "Assessment is a practice of argument from evidence based on what students say, do, and write" and that "the classroom is the richest place to gather evidence of what students know (Penuel, W., 2016). The implementation of the NGSS in Earth System Science provides a unique opportunity for geoscience education researchers to study student learning and contribute to the development of this research as well as for geoscience educators to apply these approaches and strategies in their own work with K12 inservice and preservice educators.

    Teacher education programs have adopted preparing science teachers that teach science through inquiry as an important pedagogic agenda. However, their efforts have not met with much success. While traditional explanations for this failure focus largely on preservice science teachers' knowledge, beliefs and conceptions regarding science and science teaching, this conceptual paper seeks to direct attention toward discursive practices surrounding inquiry science teaching in teacher education programs for understanding why most science teachers do not teach science through inquiry. The paper offers a theoretical framework centered on critical notions of subjection and performativity as a much needed perspective on making/becoming of science teachers through participation in discursive practices of science teacher education programs. It argues that research based on such perspectives have much potential to offer a deeper understanding of the difficult challenges teacher education programs face in preparing inquiry practicing science teachers.

  5. Science Teachers' Understanding and Practice of Inquiry-Based Instruction in Uganda

    Ssempala, Fredrick

    teachers had insufficient understanding of IBI at the beginning of the study. However, teachers from School A improved their understanding and practice of IBI after attending the PD workshop. I also found that the participating chemistry teachers' NOS epistemological views were, to some extent, related to the nature of IBI implemented in their classroom. The main internal factors the participating teachers perceived to influence their understanding and practice of IBI were their attitudes and teaching experience, whereas the external factors were lack of motivation, lack of necessary instructional materials, mode of assessment, class size, the nature of pre-service and in-service training, support from peer teachers and limited time in relation to many lessons and much content to cover Based on the above findings, I conclude that the current science teacher training in Uganda may not be improving science teachers' understanding and practice of IBI, and most of the factors are beyond their control (external). Hence, there is an urgent need for teacher educators and policymakers in Uganda to address the internal and external factors influencing science teachers' understanding and practice of IBI to improve the teaching and learning of science subjects. Additionally, more quantitative and qualitative studies should be done among teachers of different disciplines to establish how the above factors and others affect teachers' understanding and practice of IBI in developing countries like Uganda.

    Major opportunity exists to better align clinical science and clinical practice. To do so will require efforts not only to develop clinical practice guidelines, but to facilitate their application in practice. The American College of Cardiology operates a program to develop and assess the effectiveness of tools that facilitate the application of guidelines in practice. Here we review what we have learned about the process of guideline implementation, lay out the major research questions that need to be addressed, and argue that professional societies play a critical role in moving from guideline development to application.

    2011-01-01

    Neuropsychology is poised for transformations of its concepts and methods, leveraging advances in neuroimaging, the human genome project, psychometric theory, and information technologies. It is argued that a paradigm shift towards evidence-based science and practice can be enabled by innovations, including: (1) formal definition of neuropsychological concepts and tasks in cognitive ontologies; (2) creation of collaborative neuropsychological knowledgebases; and (3) design of web-based assessment methods that permit free development, large-sample implementation, and dynamic refinement of neuropsychological tests and the constructs these aim to assess. This article considers these opportunities, highlights selected obstacles, and offers suggestions for stepwise progress towards these goals. PMID:21092355

    While the achievement gap in science exists in the US, research associated with our investigation reveals some high school science programs serving diverse student bodies are successfully closing the gap. Using a mixed methods approach, we identified and investigated ten high schools in a large Southwestern state that fit the definition of "highly successful, highly diverse". By conducting interviews with science liaisons associated with each school and reviewing the literature, we developed a rubric identifying specific characteristics associated with successful science programs. These characteristics and practices included setting high expectations for students, providing extensive teacher support for student learning, and utilizing student-centered pedagogy. We used the rubric to assess the successful high school science programs and compare them to other high school science programs in the state (i.e., less successful and less diverse high school science programs). Highly successful, highly diverse schools were very different in their approach to science education when compared to the other programs. The findings from this study will help schools with diverse students to strengthen hiring practices, enhance teacher support mechanisms, and develop student-focused strategies in the classroom that increase science achievement.

  9. Gaming science innovations to integrate health systems science into medical education and practice.

    White, Earla J; Lewis, Joy H; McCoy, Lise

    2018-01-01

    Health systems science (HSS) is an emerging discipline addressing multiple, complex, interdependent variables that affect providers' abilities to deliver patient care and influence population health. New perspectives and innovations are required as physician leaders and medical educators strive to accelerate changes in medical education and practice to meet the needs of evolving populations and systems. The purpose of this paper is to introduce gaming science as a lens to magnify HSS integration opportunities in the scope of medical education and practice. Evidence supports gaming science innovations as effective teaching and learning tools to promote learner engagement in scientific and systems thinking for decision making in complex scenarios. Valuable insights and lessons gained through the history of war games have resulted in strategic thinking to minimize risk and save lives. In health care, where decisions can affect patient and population outcomes, gaming science innovations have the potential to provide safe learning environments to practice crucial decision-making skills. Research of gaming science limitations, gaps, and strategies to maximize innovations to further advance HSS in medical education and practice is required. Gaming science holds promise to equip health care teams with HSS knowledge and skills required for transformative practice. The ultimate goals are to empower providers to work in complex systems to improve patient and population health outcomes and experiences, and to reduce costs and improve care team well-being.

    For some years there has been a growing recognition of the need for changes in assessment patterns in school science. These changes include a move towards criterion-based assessment linking to objectives and an increased emphasis on the assessment of practical and experimental skills. These changes are, to a significant extent, embodied in the new GCSE assessment schemes and will thus affect all students and teachers of physics from September (1986). At least 20% of the total assessment in GCSE physics examinations must be of practical and experimental skills, and at least half of this must be carried out in the laboratory environment. One development which addresses the needs and problems outlined above is the science component of OCEA, the Oxford Certificate of Educational Achievement. Because this covers a much wider field than assessment of practical and experimental skills in physics, a brief description of the whole project is given.

    Wendell, Kristen Bethke; Lee, Hee-Sun

    2010-12-01

    Materials science, which entails the practices of selecting, testing, and characterizing materials, is an important discipline within the study of matter. This paper examines how third grade students' materials science performance changes over the course of instruction based on an engineering design challenge. We conducted a case study of nine students who participated in engineering design-based science instruction with the goal of constructing a stable, quiet, thermally comfortable model house. The learning outcome of materials science practices was assessed by clinical interviews conducted before and after the instruction, and the learning process was assessed by students' workbooks completed during the instruction. The interviews included two materials selection tasks for designing a sturdy stepstool and an insulated pet habitat. Results indicate that: (1) students significantly improved on both materials selection tasks, (2) their gains were significantly positively associated with the degree of completion of their workbooks, and (3) students who were highly engaged with the workbook's reflective record-keeping tasks showed the greatest improvement on the interviews. These findings suggest the important role workbooks can play in facilitating elementary students' learning of science through authentic activity such as engineering design.

  13. The influence of professional development on informal science educators' engagement of preschool-age audiences in science practices

    Crowl, Michele

    There is little research on professional development for informal science educators (ISEs). One particular area that ISEs need support in is how to engage preschool-age audiences in science practices. This study is part of a NSF-funded project, My Sky Tonight (MST), which looked at how to support ISEs in facilitating astronomy-themed activities with preschool-age audiences. This dissertation focuses on the influence of a six-week, online professional development workshop designed for ISEs working with preschool-age audiences. I used three primary sources of data: pre/post interviews and a video analysis task from data of 16 participants, as well as observations of implementation from a subset of seven participants who agreed to participate further. I developed and used the Phenomena-driven Practices of Science (PEPS) Framework as an analysis tool for identifying engagement in science practices. Findings from this study show that ISEs identified affective goals and rarely goals that reflect science practice engagement for their preschool-age audiences. They maintained these initial goals after the professional development workshop. ISEs describe the ways in which they engage children in science using primarily science practice-related words, but these descriptions did not show full use of science practices according to the PEPS framework. When observed implementing science activities with their preschool audiences, the ISEs demonstrated a variety of forms of science engagement, but only a few used science practices in ways consistent with the PEPS framework. Engagement in the professional development workshop did not result in a transition in the ways ISEs talk about and implement science with young children. While the write-ups for MST activities were not written in a way that supported engagement in science practices, a subset of MST activities were designed with it in mind. The professional development workshop included little time focusing on how ISEs could

  17. [Philosophy of science for psychiatric practice].

    Science.gov (United States)

    Ralston, A S G

    2010-01-01

    The prevailing view is that psychiatry has its roots in two separate methodologies: the natural sciences and the social sciences. It is assumed that these are separate domains, each with its own way of knowing. Psychiatric and psychological theories are based mainly on one or other of these two types of science; this leads to a ongoing dualism in psychiatry, which some people regard as problematical. This article aims to make a methodological contribution to the scientific and philosophical foundations of psychiatry. This philosophical and theoretical dichotomy is criticized in this article in the light of recent developments in the philosophy of science, and two methods are introduced which offer an alternative analysis: values-based practice and actor-network theory. Brief examples are given which demonstrate that a combination of these two methods can be productive for psychiatry. Values-based practice and actor-network theory provide a way of resolving the stalemate in the conflict between the physical sciences and the sciences of the mind, a conflict that is dominated by professionals. In addition these two new methods empower the professionals by not deriving legitimacy from the false image of a dichotomous science, but from a normative sense of professionalism.

    Hepatitis B (HB) is a serious infection that affects liver and caused by hepatitis B virus (HBV). HB is a serious global public health problem and the health professionals are most at risk. It is contagious and easy to be transmitted from one infected individual to another by blood to blood contact, mother to child, unprotected sexual intercourse, sharing of eating utensils and other barber shop and beauty salon equipment. The aim of this study was to assess knowledge and practices about transmissions and prevention of hepatitis B among medical and health science students on clinical attachment in Haramaya University. A cross sectional study was conducted among 322 health science and medical students who are starting clinical attachment (year II, III, IV, V and IV) from February 1-15, 2013. Self-administered structured questionnaire was used to collect information. Out of 322 distributed questionnaires, 322 were returned with a response rate of 100.0%. Majority of the students (91%) were in the age group 20-24 and 232 (72%) of the respondents were male. Majorities (95.3%) of students were not fully vaccinated against Hepatitis B and 48.4% of the students were not aware about the availability of post exposure prophylaxis for HB. Mean scores for knowledge and practice were 11.52±2.37 and 2.76±1.1 respectively. Significant and positive linear correlations between knowledge-practice (r = 0.173, p = 0.002) was observed. Study department was significantly associated with mean knowledge and practice of study respondents. This study indicates that lack of awareness about Hepatitis B, its route of transmission and modes of prevention among the medical students entering into the profession. Similarly, 95.3% the students were not fully vaccinated against Hepatitis B, which makes them vulnerable to the disease.

    Science.gov (United States)

    Zoller, Uri; Ben-Chaim, David

    1998-06-01

    A specially-designed self-assessment questionnaire (SAQHOCS), containing higher-order cognitive skills (HOCS)-type questions, was administered to 71 biology majors, enrolled in a four-year college program. The gap between students' self-assessment marking, and that of their HOCS-biased teachers (the authors), is accounted for by the prevailing LOCS-orientation and the "testing culture"—a total separation between testing and learning—in contemporary science teaching. The majority of the students in the study evaluated themselves as capable of self-assessment, and felt reasonably confident in doing so. They were quite reserved as far as the applicability of the self-assessment method to nonalgorithmic ("correct/incorrect") questions is concerned. The results of this study suggest that the potential for student self-assessment within college science teaching and learning exists. However, still a great purposed effort in HOCS-oriented teaching and learning is required in order for the student self-assessment practice to become a routine integral component of HOCS science examinations.

  2. The role of assessment infrastructures in crafting project-based science classrooms

    Science.gov (United States)

    D'Amico, Laura Marie

    In project-based science teaching, teachers engage students in the practice of conducting meaningful investigations and explanations of natural phenomena, often in collaboration with fellow students or adults. Reformers suggest that this approach can provide students with more profitable learning experiences; but for many teachers, a shift to such instruction can be difficult to manage. As some reform-minded teachers have discovered, classroom assessment can serve as a vital tool for meeting the challenges associated with project science activity. In this research, classroom assessment was viewed as an infrastructure that both students and teachers rely upon as a mediational tool for classroom activity and communications. The study explored the classroom assessment infrastructures created by three teachers involved in the Learning through Collaborative Visualization (CoVis) Project from 1993--94 to 1995--96. Each of the three teachers under study either created a new course or radically reformulated an old one in an effort to incorporate project-based science pedagogy and supporting technologies. Data in the form of interviews, classroom observations, surveys, student work, and teacher records was collected. From these data, an interpretive case study was developed for each course and its accompanying assessment infrastructure. A set of cross-case analyses was also constructed, based upon common themes that emerged from all three cases. These themes included: the assessment challenges based on the nature of project activity, the role of technology in the teachers' assessment infrastructure designs, and the influence of the wider assessment infrastructure on their course and assessment designs. In combination, the case studies and cross-case analyses describe the synergistic relationship between the design of pedagogical reforms and classroom assessment infrastructures, as well as the effectiveness of all three assessment designs.

    2017-01-01

    While there is a wealth of research evidencing the benefits of active-learning approaches, the extent to which these teaching practices are adopted in the sciences is not well known. The aim of this study is to establish an evidential baseline of teaching practices across a bachelor of science degree program at a large research-intensive Australian university. Our purpose is to contribute to knowledge on the adoption levels of evidence-based teaching practices by faculty within a science degree program and inform our science curriculum review in practical terms. We used the Teaching Practices Inventory (TPI) to measure the use of evidence-based teaching approaches in 129 courses (units of study) across 13 departments. We compared the results with those from a Canadian institution to identify areas in need of improvement at our institution. We applied a regression analysis to the data and found that the adoption of evidence-based teaching practices differs by discipline and is higher in first-year classes at our institution. The study demonstrates that the TPI can be used in different institutional contexts and provides data that can inform practice and policy. PMID:28232589

  5. X-Informatics: Practical Semantic Science

    Science.gov (United States)

    Borne, K. D.

    2009-12-01

    The discipline of data science is merging with multiple science disciplines to form new X-informatics research disciplines. They are almost too numerous to name, but they include geoinformatics, bioinformatics, cheminformatics, biodiversity informatics, ecoinformatics, materials informatics, and the emerging discipline of astroinformatics. Within any X-informatics discipline, the information granules are unique to that discipline -- e.g., gene sequences in bio, the sky object in astro, and the spatial object in geo (such as points, lines, and polygons in the vector model, and pixels in the raster model). Nevertheless the goals are similar: transparent data re-use across subdisciplines and within education settings, information and data integration and fusion, personalization of user interactions with the data collection, semantic search and retrieval, and knowledge discovery. The implementation of an X-informatics framework enables these semantic e-science research goals. We describe the concepts, challenges, and new developments associated with the new discipline of astroinformatics, and how geoinformatics provides valuable lessons learned and a model for practical semantic science within a traditional science discipline through the accretion of data science methodologies (such as formal metadata creation, data models, data mining, information retrieval, knowledge engineering, provenance, taxonomies, and ontologies). The emerging concept of data-as-a-service (DaaS) builds upon the concept of smart data (or data DNA) for intelligent data management, automated workflows, and intelligent processing.

    Funk, Christine M.

    One of the most important factors in achieving scientific literacy is for science teachers at the local level to develop a greater understanding of science education, including science content, pedagogy, and assessment. This study was designed to examine the connection between teacher learning and practice by studying the relationship between professional development and assessment implementation in the elementary science classroom. The goal was to develop a deeper understanding of the components of the STEP-uP model that served as a catalyst for change and to provide insight into how to best work with teachers in order to develop a more scientifically literate population. Four essential questions guided this research. What kinds of opportunities does STEP-uP provide for elementary school teachers to improve their assessment practices in science? In what ways did STEP-uP training affect assessment practices by teachers? How, if at all, are the assessment practices modified by teachers? What are the most salient features of the STEP-uP professional development model that allow for change and growth in assessment practices in elementary science classrooms and for education at large? The research method for this study was educational connoisseurship and criticism. I developed rich descriptions and interpretations based on observations, interviews, and artifacts from six classroom teachers which were then compared and contrasted to the goals of STEP-uP described in their literature, by the assessment coordinator, and an observation of a STEP-uP training. Key findings include: (1) collaboration and collegial support must be integral to sustain change; (2) clearly articulated goals form one, cohesive vision for professional development that must be integral to all components of the program; (3) multiple entry points help encourage participation and honor differences between teachers' personal and professional needs; and, (4) classroom structures such as time, classroom

  10. Virtual school teacher's science efficacy beliefs: The effects of community of practice on science-teaching efficacy beliefs

    Science.gov (United States)

    Uzoff, Phuong Pham

    The purpose of this study was to examine how much K-12 science teachers working in a virtual school experience a community of practice and how that experience affects personal science-teaching efficacy and science-teaching outcome expectancy. The study was rooted in theoretical frameworks from Lave and Wenger's (1991) community of practice and Bandura's (1977) self-efficacy beliefs. The researcher used three surveys to examine schoolteachers' experiences of a community of practice and science-teaching efficacy beliefs. The instrument combined Mangieri's (2008) virtual teacher demographic survey, Riggs and Enochs (1990) Science-teaching efficacy Beliefs Instrument-A (STEBI-A), and Cadiz, Sawyer, and Griffith's (2009) Experienced Community of Practice (eCoP) instrument. The results showed a significant linear statistical relationship between the science teachers' experiences of community of practice and personal science-teaching efficacy. In addition, the study found that there was also a significant linear statistical relationship between teachers' community of practice experiences and science-teaching outcome expectancy. The results from this study were in line with numerous studies that have found teachers who are involved in a community of practice report higher science-teaching efficacy beliefs (Akerson, Cullen, & Hanson, 2009; Fazio, 2009; Lakshmanan, Heath, Perlmutter, & Elder, 2011; Liu, Lee, & Lin, 2010; Sinclair, Naizer, & Ledbetter, 2010). The researcher concluded that school leaders, policymakers, and researchers should increase professional learning opportunities that are grounded in social constructivist theoretical frameworks in order to increase teachers' science efficacy.

  11. Practical work in secondary science a minds-on approach

    Abrahams, Ian

    2011-01-01

    Practical work is an essential feature of secondary science education. However, questions have been raised by some science educators about its effectiveness as a teaching and learning strategy. Whilst such an approach is generally effective in getting pupils to do things with objects and materials, it is seen as relatively ineffective in developing their conceptual understanding of the associated scientific ideas and concepts. Ian Abrahams argues that this is because it is practiced as a 'hands-on' rather than 'minds-on' activity. Abrahams draws together theory and practice on effective teaching and learning in practical work in science - covering biology, chemistry and physics. He provides clear guidance to ensure that students are encouraged and supported to be 'minds-on' as well as a 'hands-on' so that they can make the most of this learning experience. An invaluable text for inspiringaspiring andexperienced secondary science professionals, especially for those on M-level secondary science PGCE programmes.

    Full Text Available The paper reports a study carried out on the utilisation of the Internet by agricultural science teachers in Lagos state focusing on uses, practices, and barriers. A questionnaire was developed based on literature and was administered to 300 agricultural science teachers in Lagos schools. 275 questionnaires properly completed were analyzed. Data reveal that 130 teachers are using the Internet for teaching agricultural science in classrooms as well as for various activities that enhance their professional development. Nevertheless, it was found that agricultural science teachers in Lagos State have not fully utilised the Internet because of barriers related to time factor, accessibility, and facilities. It is suggested that for the proliferation of Internet practices, there needs to be an increase in funding for technology, an introduction of computer/technology education, a provision of pedagogical training for teachers, and a provision of administrational support.

  15. Exploring the meaning of practicing classroom inquiry from the perspectives of National Board Certified Science Teachers

    Science.gov (United States)

    Karaman, Ayhan

    Inquiry has been one of the most prominent terms of the contemporary science education reform movement (Buck, Latta, & Leslie-Pelecky, 2007; Colburn, 2006; Settlage, 2007). Practicing classroom inquiry has maintained its central position in science education for several decades because science education reform documents promote classroom inquiry as the potential savior of science education from its current problems. Likewise, having the capabilities of teaching science through inquiry has been considered by National Board for Professional Teaching Standards [NBPTS] as one of the essential elements of being an accomplished science teacher. Successful completion of National Board Certification [NBC] assessment process involves presenting a clear evidence of enacting inquiry with students. Despite the high-profile of the word inquiry in the reform documents, the same is not true in schools (Crawford, 2007). Most of the science teachers do not embrace this type of approach in their everyday teaching practices of science (Johnson, 2006; Luera, Moyer, & Everett, 2005; Smolleck, Zembal-Saul, & Yoder, 2006; Trumbull, Scarano, & Bonney, 2006). And the specific meanings attributed to inquiry by science teachers do not necessarily match with the original intentions of science education reform documents (Matson & Parsons, 2006; Wheeler, 2000; Windschitl, 2003). Unveiling the various meanings held by science teachers is important in developing better strategies for the future success of science education reform efforts (Jones & Eick, 2007; Keys & Bryan, 2001). Due to the potential influences of National Board Certified Science Teachers [NBCSTs] on inexperienced science teachers as their mentors, examining inquiry conceptions of NBCSTs is called for. How do these accomplished practitioners understand and enact inquiry? The purpose of this dissertation research study was twofold. First, it investigated the role of NBC performance assessment process on the professional development

  16. Constitutions of Nature by Teacher Practice and Discourse in Ontario Grade 9 and 10 Academic Science

    Science.gov (United States)

    Hoeg, Darren Glen

    This thesis presents an ethnographic study, based broadly on principles and methods of institutional ethnography, on the constitution of nature by nine Ontario Grade 9 and 10 Academic Science teachers. The intent of this methodological approach is to examine how the daily practice of participants works toward constituting nature in specific ways that are coordinated by the institution (Ontario public school and/or school science). Critical Discourse Analysis and general inductive analysis were performed on interview transcripts, texts related to teaching science selected by participants, and policy documents (i.e. curriculum; assessment policy) that coordinate science teacher practice. Findings indicate specific, dominant, and relatively uniform ontological and epistemological constitutions of nature. Nature was frequently constituted as a remote object, distant from and different than students studying it. More complex representations included constituting nature as a model, machine, or mathematical algorithm. Epistemological constitutions of nature were enacted through practices that engaged students in manipulating nature; controlling nature, and dominating nature. Relatively few practices that allow students to construct different constitutions of nature than those prioritized by the institution were observed. Dominant constitutions generally assume nature is simply the material to study, from which scientific knowledge can be obtained, with little ethical or moral consideration about nature itself, or how these constitutions produce discourse and relationships that may be detrimental to nature. Dominant constitutions of nature represent a type of objective knowledge that is prioritized, and made accessible to students, through science activities that attain a position of privilege in local science teacher cultures. The activities that allow students to attain the requisite knowledge of nature are collected, collated, and shared among existing science teachers

    Genel, Abdulkadir; Sami Topçu, Mustafa

    2016-01-01

    Background: Despite a growing body of research and curriculum reforms including socioscientific issues (SSI) across the world, how preservice science teachers (PST) or in-service science teachers can teach SSI in science classrooms needs further inquiry. Purpose: The purpose of this study is to describe the abilities of PSTs to teach SSI in middle school science classrooms, and the research question that guided the present study is: How can we characterize Turkish PSTs' SSI-based teaching practices in middle school science classrooms (ages 11-14)? Sample: In order to address the research question of this study, we explored 10 Turkish PSTs' SSI-based teaching practices in middle school science classrooms. A purposeful sampling strategy was used, thus, PSTs were specifically chosen because they were ideal candidates to teach SSI and to integrate SSI into the science curricula since they were seniors in the science education program who had to take the field experience courses. Design and method: The participants' SSI teaching practices were characterized in light of qualitative research approach. SSI-based teaching practices were analyzed, and the transcripts of all videotape recordings were coded by two researchers. Results: The current data analysis describes Turkish PSTs' SSI-based teaching practices under five main categories: media, argumentation, SSI selection and presentation, risk analysis, and moral perspective. Most of PSTs did not use media resources in their lesson and none of them considered moral perspective in their teaching. While the risk analyses were very simple and superficial, the arguments developed in the classrooms generally remained at a simple level. PSTs did not think SSI as a central topic and discussed these issues in a very limited time and at the end of the class period. Conclusions: The findings of this study manifest the need of the reforms in science education programs. The present study provides evidence that moral, media

    2018-03-01

    Preparing teachers to teach science consistent with current reforms in science education is a daunting enterprise given a lack of high-quality science professional development (PD) adaptable across various contexts (Wilson 2013). This study examines the impact of a comprehensive professional development program on middle school teachers' disciplinary content knowledge and instructional practices. In this mixed methods investigation, data sources included classroom observations, content knowledge assessments, surveys, and a range of interviews. The teachers in the program showed significant improvements in their disciplinary content knowledge and demonstrated through their enactment of a reform-based curriculum, a range of ability levels to translate their knowledge into instructional practices consistent with the principles espoused in the PD. We conclude that programs that attend to elements of effective PD identified in the literature can positively impact middle school science teachers' enactment of reform-based science teaching. Our findings extend these elements to include the strategic engagement of school and district leadership and the provision of a safe learning space for teachers to collectively engage in reciprocal learning and critical practice. This study has worldwide implications for designing PD for science teachers and for extending our understanding of the impact of each element.

    In order to create conditions for students' meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students' scientific literacy. Better understanding how science teachers' instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students' science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers' value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers' instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed.

    While there is a wealth of research evidencing the benefits of active-learning approaches, the extent to which these teaching practices are adopted in the sciences is not well known. The aim of this study is to establish an evidential baseline of teaching practices across a bachelor of science degree program at a large research-intensive Australian university. Our purpose is to contribute to knowledge on the adoption levels of evidence-based teaching practices by faculty within a science degree program and inform our science curriculum review in practical terms. We used the Teaching Practices Inventory (TPI) to measure the use of evidence-based teaching approaches in 129 courses (units of study) across 13 departments. We compared the results with those from a Canadian institution to identify areas in need of improvement at our institution. We applied a regression analysis to the data and found that the adoption of evidence-based teaching practices differs by discipline and is higher in first-year classes at our institution. The study demonstrates that the TPI can be used in different institutional contexts and provides data that can inform practice and policy. © 2017 M. J. Drinkwater et al.

  2. Responsible research and innovation indicators for science education assessment: how to measure the impact?

    Science.gov (United States)

    Heras, Maria; Ruiz-Mallén, Isabel

    2017-12-01

    The emerging paradigm of responsible research and innovation (RRI) in the European Commission policy discourse identifies science education as a key agenda for better equipping students with skills and knowledge to tackle complex societal challenges and foster active citizenship in democratic societies. The operationalisation of this broad approach in science education demands, however, the identification of assessment frameworks able to grasp the complexity of RRI process requirements and learning outcomes within science education practice. This article aims to shed light over the application of the RRI approach in science education by proposing a RRI-based analytical framework for science education assessment. We use such framework to review a sample of empirical studies of science education assessments and critically analyse it under the lenses of RRI criteria. As a result, we identify a set of 86 key RRI assessment indicators in science education related to RRI values, transversal competences and experiential and cognitive aspects of learning. We argue that looking at science education through the lenses of RRI can potentially contribute to the integration of metacognitive skills, emotional aspects and procedural dimensions within impact assessments so as to address the complexity of learning.

  3. [Qualitative translational science in clinical practice].

    2013-10-01

    Qualitative translational research refers to the "bench-to-bedside" enterprise of harnessing knowledge from the basic sciences to produce new treatment options or nursing interventions for patients. Three evidence-based translational problems related to qualitative translational research discussed this year address the interfaces among the nursing paradigm, the basic sciences, and clinical nursing work. This article illustrates the definition of translational science and translational blocks of evidence-based practice; discusses the qualitative research perspective in evidence synthesis, evidence translation and evidence utilization; and discusses the research questions that must be answered to solve the problems of the three translational gaps from the qualitative research perspective. Qualitative inquiry has an essential role to play in efforts to improve current healthcare-provider nursing interventions, experiences, and contexts. Thus, it is vital to introduce qualitative perspectives into evidence-based practice from the knowledge discovery through to the knowledge implementation process.

    It is commonly recognised that practical work has a distinctive and central role in science teaching and learning. Although a large number of studies have addressed the definitions, typologies, and purposes of practical work, few have consulted practicing science teachers. This study explored science teachers' perceptions of experimentation for the purpose of restructuring school practical work in view of science practice. Qualitative interviews were conducted with 87 science teachers at the secondary school level. In the interviews, science teachers were asked to make a comparison between students' experiments and scientific experiments. Eight dimensions of experimentation were generated from the qualitative data analysis, and the distributions of these eight dimensions between the two types of experiments were compared and analysed. An ideal model of practical work was suggested for restructuring practical work at the secondary school level, and some issues related to the effective enactment of practical work were discussed.

    2011-11-01

    Full Text Available This is a review of the role of practical work in UK’s secondary school science lessons, the impact that practical work has in the promotion of science, the challenges created through use of non-specialist science teachers and a possible additional role for science technicians. The paper considers how improved deployment of suitably experienced school science technicians and their recognition, by schools’ management, for their involvement in the delivery of training in the use of practical work, for less experienced teachers, could benefit schools and their students. This together with its companion paper endeavours to show how the more effective use of practical work and technicians can encourage more students to select science at higher, non-compulsory levels.

    Earle, Sarah

    2014-05-01

    Background:Since the discontinuation of Standard Attainment Tests (SATs) in science at age 11 in England, pupil performance data in science reported to the UK government by each primary school has relied largely on teacher assessment undertaken in the classroom. Purpose:The process by which teachers are making these judgements has been unclear, so this study made use of the extensive Primary Science Quality Mark (PSQM) database to obtain a 'snapshot' (as of March 2013) of the approaches taken by 91 English primary schools to the formative and summative assessment of pupils' learning in science. PSQM is an award scheme for UK primary schools. It requires the science subject leader (co-ordinator) in each school to reflect upon and develop practice over the course of one year, then upload a set of reflections and supporting evidence to the database to support their application. One of the criteria requires the subject leader to explain how science is assessed within the school. Sample:The data set consists of the electronic text in the assessment section of all 91 PSQM primary schools which worked towards the Quality Mark in the year April 2012 to March 2013. Design and methods:Content analysis of a pre-existing qualitative data set. Text in the assessment section of each submission was first coded as describing formative or summative processes, then sub-coded into different strategies used. Results:A wide range of formative and summative approaches were reported, which tended to be described separately, with few links between them. Talk-based strategies are widely used for formative assessment, with some evidence of feedback to pupils. Whilst the use of tests or tracking grids for summative assessment is widespread, few schools rely on one system alone. Enquiry skills and conceptual knowledge were often assessed separately. Conclusions:There is little consistency in the approaches being used by teachers to assess science in English primary schools. Nevertheless

Objective: This study shows the following research question: which dimensions provide sustainability for the formulation of a policy geared to open science and its practices in the Brazilian context? The aim of this study is to discuss the dimensions that support transversely the formulation of a policy for open science and its scientific practices. Methodology:Theoretically, the study is guided by the fourth scientific paradigm grounded in the e-Science. The methodology is supported by Bufrem’s studies (2013, which propose an alternative and multidimensional model for analysis and discussion of scientific research. Technically, the literature review and documentary survey were the methods used on the Data Lifecycle scientific model, laws and international agreements.For this study purpose, five dimensions were proposed, namely: epistemological, political, ethical-legal-cultural, morphological, and technological. Results: This studyunderstands that these dimensions substantiate an information policy or the development of minimum guidelines for the open science agenda in Brazil. Conclusions: The dimensions put away the reductionist perspective on survey data and they conducted the study for the multi-dimensional and multi-relational vision of open science.

  8. A New Era of Science Education: Science Teachers' Perceptions and Classroom Practices of Science, Technology, Engineering, and Mathematics (STEM) Integration

    Wang, Hui-Hui

    Quality STEM education is the key in helping the United States maintain its lead in global competitiveness and in preparing for new economic and security challenges in the future. Policymakers and professional societies emphasize STEM education by legislating the addition of engineering standards to the existing science standards. On the other hand, the nature of the work of most STEM professionals requires people to actively apply STEM knowledge to make critical decisions. Therefore, using an integrated approach to teaching STEM in K-12 is expected. However, science teachers encounter numerous difficulties in adapting the new STEM integration reforms into their classrooms because of a lack of knowledge and experience. Therefore, high quality STEM integration professional development programs are an urgent necessity. In order to provide these high quality programs, it is important to understand teachers' perceptions and classroom practices regarding STEM integration. A multiple-case study was conducted with five secondary school science teachers in order to gain a better understanding of teachers' perceptions and classroom practices in using STEM integration. This study addresses the following research questions: 1) What are secondary school science teachers' practices of STEM integration? 2) What are secondary science teachers' overall perceptions of STEM integration? and 3) What is the connection between secondary science teachers' perceptions and understanding of STEM integration with their classroom practices? This research aims to explore teachers' perceptions and classroom practices in order to set up the baseline for STEM integration and also to determine STEM integration professional development best practices in science education. Findings from the study provide critical data for making informed decision about the direction for STEM integration in science education in K-12.

  10. Investigating Assessment Bias for Constructed Response Explanation Tasks: Implications for Evaluating Performance Expectations for Scientific Practice

    Science.gov (United States)

    Federer, Meghan Rector

    Assessment is a key element in the process of science education teaching and research. Understanding sources of performance bias in science assessment is a major challenge for science education reforms. Prior research has documented several limitations of instrument types on the measurement of students' scientific knowledge (Liu et al., 2011; Messick, 1995; Popham, 2010). Furthermore, a large body of work has been devoted to reducing assessment biases that distort inferences about students' science understanding, particularly in multiple-choice [MC] instruments. Despite the above documented biases, much has yet to be determined for constructed response [CR] assessments in biology and their use for evaluating students' conceptual understanding of scientific practices (such as explanation). Understanding differences in science achievement provides important insights into whether science curricula and/or assessments are valid representations of student abilities. Using the integrative framework put forth by the National Research Council (2012), this dissertation aimed to explore whether assessment biases occur for assessment practices intended to measure students' conceptual understanding and proficiency in scientific practices. Using a large corpus of undergraduate biology students' explanations, three studies were conducted to examine whether known biases of MC instruments were also apparent in a CR instrument designed to assess students' explanatory practice and understanding of evolutionary change (ACORNS: Assessment of COntextual Reasoning about Natural Selection). The first study investigated the challenge of interpreting and scoring lexically ambiguous language in CR answers. The incorporation of 'multivalent' terms into scientific discourse practices often results in statements or explanations that are difficult to interpret and can produce faulty inferences about student knowledge. The results of this study indicate that many undergraduate biology majors

    2014-07-01

    To summarize key issues in the eHealth field from an implementation science perspective and to highlight illustrative processes, examples and key directions to help more rapidly integrate research, policy and practice. We present background on implementation science models and emerging principles; discuss implications for eHealth research; provide examples of practical designs, measures and exemplar studies that address key implementation science issues; and make recommendations for ways to more rapidly develop and test eHealth interventions as well as future research, policy and practice. The pace of eHealth research has generally not kept up with technological advances, and many of our designs, methods and funding mechanisms are incapable of providing the types of rapid and relevant information needed. Although there has been substantial eHealth research conducted with positive short-term results, several key implementation and dissemination issues such as representativeness, cost, unintended consequences, impact on health inequities, and sustainability have not been addressed or reported. Examples of studies in several of these areas are summarized to demonstrate this is possible. eHealth research that is intended to translate into policy and practice should be more contextual, report more on setting factors, employ more responsive and pragmatic designs and report results more transparently on issues important to potential adopting patients, clinicians and organizational decision makers. We outline an alternative development and assessment model, summarize implementation science findings that can help focus attention, and call for different types of more rapid and relevant research and funding mechanisms.

    2014-02-01

    The landscape of science education is being transformed by the new Framework for Science Education (National Research Council, A framework for K-12 science education: practices, crosscutting concepts, and core ideas. The National Academies Press, Washington, DC, 2012), which emphasizes the centrality of scientific practices—such as explanation, argumentation, and communication—in science teaching, learning, and assessment. A major challenge facing the field of science education is developing assessment tools that are capable of validly and efficiently evaluating these practices. Our study examined the efficacy of a free, open-source machine-learning tool for evaluating the quality of students' written explanations of the causes of evolutionary change relative to three other approaches: (1) human-scored written explanations, (2) a multiple-choice test, and (3) clinical oral interviews. A large sample of undergraduates (n = 104) exposed to varying amounts of evolution content completed all three assessments: a clinical oral interview, a written open-response assessment, and a multiple-choice test. Rasch analysis was used to compute linear person measures and linear item measures on a single logit scale. We found that the multiple-choice test displayed poor person and item fit (mean square outfit >1.3), while both oral interview measures and computer-generated written response measures exhibited acceptable fit (average mean square outfit for interview: person 0.97, item 0.97; computer: person 1.03, item 1.06). Multiple-choice test measures were more weakly associated with interview measures (r = 0.35) than the computer-scored explanation measures (r = 0.63). Overall, Rasch analysis indicated that computer-scored written explanation measures (1) have the strongest correspondence to oral interview measures; (2) are capable of capturing students' normative scientific and naive ideas as accurately as human-scored explanations, and (3) more validly detect understanding

  14. Rasch Validation of a Measure of Reform-Oriented Science Teaching Practices

    Growing evidence from recent curriculum documents and previous research suggests that reform-oriented science teaching practices promote students' conceptual understanding, levels of achievement, and motivation to learn, especially when students are actively engaged in constructing their ideas through scientific inquiries. However, it is difficult to identify to what extent science teachers engage students in reform-oriented teaching practices (RTPs) in their science classrooms. In order to exactly diagnose the current status of science teachers' implementation of the RTPs, a valid and reliable instrument tool is needed. The principles of validity and reliability are fundamental cornerstones in developing a robust measurement tool. As such, this study was motivated by the desire to point out the limitations of the existing statistical and psychometric analyses and to further examine the validation of the RTP survey instrument. This paper thus aims at calibrating the items of the RTPs for science teachers using the Rasch model. The survey instrument scale was adapted from the 2012 National Survey of Science and Mathematics Education (NSSME) data. A total of 3701 science teachers from 1403 schools from across the USA participated in the NSSME survey. After calibrating the RTP items and persons on the same scale, the RTP instrument well represented the population of US science teachers. Model-data fit determined by Infit and Outfit statistics was within an appropriate range (0.5-1.5), supporting the unidimensional structure of the RTPs. The ordered category thresholds and the probability of the thresholds showed that the five-point rating scale functioned well. The results of this study support the use of the RTP measure from the 2012 NSSME in assessing usage of RTPs.

  15. Examining Science Teachers' Development of Interdisciplinary Science Inquiry Pedagogical Knowledge and Practices

    The current literature relates to how teachers develop knowledge and practice of science inquiry, but little has been reported on how teachers develop interdisciplinary science inquiry (ISI) knowledge and practice. This study examines the effect of university research experiences, ongoing professional development, and in-school support on teachers' development of ISI pedagogical knowledge and practices. It centers on documenting diverse teachers' journeys of experiencing ISI as well as developing knowledge of ISI. It was found that there was variation in ISI understanding and practice among the teachers as a result of the combination of teachers' experiences, beliefs, and participation. Thus, in order to help teachers develop ISI knowledge and pedagogy, barriers to ISI knowledge development and implementation must also be addressed. Professional developers must articulate clear program goals to all stakeholders including an explicit definition of ISI and the ability to recognize ISI attributes during research experiences as well as during classroom implementation. Teachers must also be held accountable for participation and reflection in all aspects of professional development. Program developers must also take into consideration teachers' needs, attitudes, and beliefs toward their students when expecting changes in teachers' cognition and behavior to teach inquiry-rich challenging science.

    Full Text Available This paper reports the results of a study made on the impact of improved deployment of science technicians in the classroom could directly benefit students in practical science investigations. Science technicians are skilled individuals whose understanding of practical work is a valuable resource not being used of in support of students understanding of science. Aspects of practical work and technician support were scrutinised, through information attained from a post-16 student survey to improve understanding about this teaching tool, to establish if it was being used to its full potential within science lessons. Analysis was also made of students’ perceptions of school science. The main outcomes were that the majority of students enjoyed science practical work and felt that science could not be taught without it. Students studying science at pre-university level attained a greater understanding, through participating in relevant practical work, than students who had studied it at earlier, compulsory levels. Students reported that science technicians provide impact on student learning when contact time was the greatest.

    2017-08-01

    Various inquiry approaches have been promoted in science classrooms as a way for students to engage in, and have a deeper understanding of scientific discourse. However, there is a paucity of empirical evidence to suggest how children's actions and engagement in these approaches, or practical epistemologies (Sandoval, Science Education 89(4): 634-656, 2005), may contribute to the development of their personal epistemologies, or their views about the nature of knowledge and knowing and the nature of learning. This paper puts forth the conceptualization and development of the Practical Epistemology in Science Survey (PESS) instrument, a 26-item Likert-scale self-assessment which measures how students view their individual and social participation in the classroom scientific community. Data were collected from 4th-6th-grade students (n = 1019) in the USA and a psychometric evaluation of the reliability, validity, and dimensionality of the instrument was conducted. The Cronbach's alpha value indices for all subsets of items of the PESS suggest a strong reliability of the instrument (α ≥ .80). The development of the PESS may be useful in science education research to (a) detect changes to students' beliefs about knowledge and knowledge development; (b) identify dispositions and beliefs which may or may not be in line with the aims and values of various pedagogical approaches; (c) monitor the process of change, e.g., time it takes for students to change their approaches and beliefs with respect to teacher practice; and, (d) overall, to provide an understanding of how students' formal epistemologies are developed and informed by the affordances in science classrooms.

    The purpose of this study was to explore youth's purposes and motivations for engaging in science through the lens of science practices. The construct of science practices allowed me to see science in youths' lives in a holistic way, shaped by social, political, historical, economic and cultural forces. The framework for understanding urban youths' science practices is grounded in the intersections of critical and feminist theory, sociocultural learning theories, especially as applied in research in urban science education, and recent work in critical literacy studies. As I explored the answers to my research questions---(1) When 5th grade youth, living in predominantly Latino communities struggling with urban poverty, engage in science how and why do they co-opt science in ways that result in changes in participation in science? (2) What are the science practices that facilitate youths' coopting of science? And how are those practices framed by context (school, out-of-school), content (LiFE curriculum), and funds of knowledge? (3) In what ways are science practices expressions of youths' scientific literacy? And (4) In what ways do youth use science practices as tools for expressing identities and agency?---I engaged in feminist ethnography with embedded case studies. Data were collected in 2004 in school and in out of school settings. I recorded numerous informal conversations, interviews, and observations both during after-school and students' regular science and non-science classes. Findings describe how and why students co-opted science for purposes that make sense for their lives. These purposes included gaining and activating resources, building and maintaining social relationships, bridging home and school knowledge, positioning themselves with authority, and constructing science identities. Findings also explored what practices facilitated youth's co-opting of science. I highlighted three practices: making ideas public, storytelling and prioritizing and

    2009-06-01

    This longitudinal study of middle school science teachers explored the relationship between effective science instruction, as defined by the National Science Education Standards (NRC in National science education standards. National Academy Press, Washington, DC, 1996), and student achievement in science. Eleven teachers participated in a three year study of teacher effectiveness, determined by the LSC Classroom Observation Protocol (Horizon Research, Inc. in Local Systemic Change Classroom Observation Protocol. May 1, 2002) and student achievement, which was assessed using the Discovery Inquiry Test in Science. Findings in this study revealed the positive impact that effective science teachers have on student learning, eliminating achievement gaps between White and Non-White students. Case studies of three teachers, both effective and ineffective explore the beliefs and experiences that influence teachers to change, or not to change practice. This study provides justification for teaching science effectively to narrow achievement gaps in science and provides insight to stakeholders in science education as to how to support teachers in becoming more effective, through addressing existing teacher beliefs and providing experiences that challenge those beliefs.

  8. High School Physics Students' Personal Epistemologies and School Science Practice

    2017-11-01

    This case study explores students' physics-related personal epistemologies in school science practices. The school science practices of nine eleventh grade students in a physics class were audio-taped over 6 weeks. The students were also interviewed to find out their ideas on the nature of scientific knowledge after each activity. Analysis of transcripts yielded several epistemological resources that students activated in their school science practice. The findings show that there is inconsistency between students' definitions of scientific theories and their epistemological judgments. Analysis revealed that students used several epistemological resources to decide on the accuracy of their data including accuracy via following the right procedure and accuracy via what the others find. Traditional, formulation-based, physics instruction might have led students to activate naive epistemological resources that prevent them to participate in the practice of science in ways that are more meaningful. Implications for future studies are presented.

    Science software is integral to the scientific process and must be developed and managed in a sustainable manner to ensure future access to scientific data and related resources. Organizations that are part of the scientific enterprise, as well as members of the scientific community who work within these entities, can contribute to the sustainability of science software and to practices that improve scientific community capabilities for science software sustainability. As science becomes increasingly digital and therefore, dependent on software, improving community practices for sustainable science software will contribute to the sustainability of science. Members of the Earth science informatics community, including scientific data producers and distributers, end-user scientists, system and application developers, and data center managers, use science software regularly and face the challenges and the opportunities that science software presents for the sustainability of science. To gain insight on practices needed for the sustainability of science software from the science software experiences of the Earth science informatics community, an interdisciplinary group of 300 community members were asked to engage in simultaneous roundtable discussions and report on their answers to questions about the requirements for improving scientific software sustainability. This paper will present an analysis of the issues reported and the conclusions offered by the participants. These results provide perspectives for science software sustainability practices and have implications for actions that organizations and their leadership can initiate to improve the sustainability of science software.

    2009-12-01

    The purpose of this proposed research study was to identify actual teaching practices/instructional strategies for online science courses. The identification of these teaching practices/instructional strategies could be used to compile a set of teaching practices/instructional strategies for virtual high school and online academy science instructors. This study could assist online science instructors by determining which teaching practices/instructional strategies were preferred for the online teaching environment. The literature reviewed the role of online and face-to-face instructional strategies, then discussed and elaborated on the science instructional strategies used by teachers, specifically at the secondary level. The current literature did not reflect an integration of these areas of study. Therefore, the connectedness of these two types of instructional strategies and the creation of a set of preferred instructional practices for online science instruction was deemed necessary. For the purpose of this study, the researcher designed a survey for face-to-face and online teachers to identify preferred teaching practices, instructional strategies, and types of technology used when teaching high school science students. The survey also requested demographic data information from the faculty members, including years of experience, subject(s) taught, and whether the teacher taught in a traditional classroom or online, to determine if any of those elements affect differences in faculty perceptions with regard to the questions under investigation. The findings from the current study added to the literature by demonstrating the differences and the similarities that exist between online and face-to-face instruction. Both forms of instruction tend to rely on student-centered approaches to teaching. There were many skills that were similar in that both types of instructors tend to focus on implementing the scientific method. The primary difference is the use of

    Policy on officer-involved shootings is critically reviewed and errors in applying scientific knowledge identified. Identifying and evaluating the most relevant science to a field-based problem is challenging. Law enforcement administrators with a clear understanding of valid science and application are in a better position to utilize scientific knowledge for the benefit of their organizations and officers. A recommended framework is proposed for considering the validity of science and its application. Valid science emerges via hypothesis testing, replication, extension and marked by peer review, known error rates, and general acceptance in its field of origin. Valid application of behavioral science requires an understanding of the methodology employed, measures used, and participants recruited to determine whether the science is ready for application.

    Morales, Marlene

    In this study, a mixed methods approach was used to gather descriptive exploratory information regarding the teaching of science to middle grades students with learning disabilities within a general education classroom. The purpose of this study was to examine teachers' beliefs and their practices concerning providing equitable opportunities for students with learning disabilities in a general education science classroom. Equitable science teaching practices take into account each student's differences and uses those differences to inform instructional decisions and tailor teaching practices based on the student's individualized learning needs. Students with learning disabilities are similar to their non-disabled peers; however, they need some differentiation in instruction to perform to their highest potential achievement levels (Finson, Ormsbee, & Jensen, 2011). In the quantitative phase, the purpose of the study was to identify patterns in the beliefs of middle grades science teachers about the inclusion of students with learning disabilities in the general education classroom. In the qualitative phase, the purpose of the study was to present examples of instruction in the classrooms of science education reform-oriented middle grades science teachers. The quantitative phase of the study collected data from 274 sixth through eighth grade teachers in the State of Florida during the 2007--2008 school year using The Teaching Science to Students with Learning Disabilities Inventory. Overall, the quantitative findings revealed that middle grades science teachers held positive beliefs about the inclusion of students with learning disabilities in the general education science classroom. The qualitative phase collected data from multiple sources (interviews, classroom observations, and artifacts) to develop two case studies of reform-oriented middle grades science teachers who were expected to provide equitable science teaching practices.

    Full Text Available Integrating research experiences into undergraduate life sciences curricula in the form of course-based undergraduate research experiences (CUREs can meet national calls for education reform by giving students the chance to “do science.” In this article, we provide a step-by-step practical guide to help instructors assess their CUREs using best practices in assessment. We recommend that instructors first identify their anticipated CURE learning outcomes, then work to identify an assessment instrument that aligns to those learning outcomes and critically evaluate the results from their course assessment. To aid instructors in becoming aware of what instruments have been developed, we have also synthesized a table of “off-the-shelf” assessment instruments that instructors could use to assess their own CUREs. However, we acknowledge that each CURE is unique and instructors may expect specific learning outcomes that cannot be assessed using existing assessment instruments, so we recommend that instructors consider developing their own assessments that are tightly aligned to the context of their CURE.

  15. Factors affecting science reform: Bridging the gap between reform initiatives and teaching practices

    Pensak, Karl John

    In response to the perceived deficiencies in science education today, and to the expressed need for research into the culture of schools (due primarily to the failure of many science reforms in the past), this study used a broad based approach to study the gap between science education research and science education practice. This study identified 47 factors that may encourage or inhibit science curriculum reform. A survey was conducted to determine which factors were perceived to be important by local and national K-12 classroom teachers, science supervisors/coordinators, and college/university professors. Continual staff development (scheduled as part of teachers' work day/week/month), funding (for long-term staff development, teacher training and support, science laboratory facilities and materials), teacher motivation and "ownership" of the reform, the need for collaborative opportunities for classroom teachers, teachers' college preparation, textbook reform, community support, and reform initiatives that are "in tune" with assessment, are major factors identified as having a substantial affect on the successful adoption, implementation, and institutionalization of science reforms.

    Existing literature highlights a critical gap between science and practice in clinical psychology. The internship year is a "capstone experience"; training in methods of scientific evaluation should be integrated with the development of advanced clinical competencies. We provide a rationale for continued exposure to research during the clinical internship year, including, (a) critical examination and integration of the literature regarding evidence-based treatment and assessment, (b) participation in faculty-based and independent research, and (c) orientation to the science and strategy of grantsmanship. Participation in research provides exposure to new empirical models and can foster the development of applied research questions. Orientation to grantsmanship can yield an initial sense of the "business of science." Internship provides an important opportunity to examine the challenges to integrating the clinical evidence base into professional practice; for that reason, providing research exposure on internship is an important strategy in training the next generation of pediatric psychologists.

    Renwick, Chris

    2009-03-01

    From the Victorian era to our own, critics of Herbert Spencer have portrayed his science-based philosophical system as irrelevant to the concerns of practicing scientists. Yet, as a number of scholars have recently argued, an extraordinary range of reformist and experimental projects across the human and life sciences took their bearings from Spencer's work. This essay examines Spencerian science as practiced by the biologist, sociologist, and town planner Patrick Geddes (1854-1932). Through a close examination of his experimental natural history of the late 1870s and early 1880s, his wider writings on the evolutionary process in the 1880s, and his efforts later in that decade to improve the slums of Edinburgh, this essay reveals Geddes's deep, unifying, and energizing commitment to Spencer's program. Recapturing that commitment can not only help historians rethink Spencerian science as practice but also suggest ways of overcoming the dichotomy between elite ideas and practical activity that bedevils much contemporary historiography of science.

    Panzarella, Karen Joanne

    To test the success of integrated curricula in schools of health sciences, meaningful measurements of student performance are required to assess clinical competency. This research project analyzed a new performance assessment tool, the Integrated Standardized Patient Examination (ISPE), for assessing clinical competency: specifically, to assess Doctor of Physical Therapy (DPT) students' clinical competence as the ability to integrate basic science knowledge with clinical communication skills. Thirty-four DPT students performed two ISPE cases, one of a patient who sustained a stroke and the other a patient with a herniated lumbar disc. Cases were portrayed by standardized patients (SPs) in a simulated clinical setting. Each case was scored by an expert evaluator in the exam room and then by one investigator and the students themselves via videotape. The SPs scored each student on an overall encounter rubric. Written feedback was obtained from all participants in the study. Acceptable reliability was demonstrated via inter-rater agreement as well as inter-rater correlations on items that used a dichotomous scale, whereas the items requiring the use of the 4-point rubric were somewhat less reliable. For the entire scale both cases had a significant correlation between the Expert-Investigator pair of raters, for the CVA case r = .547, p performances on the ISPE with other independent estimates of students' competence. The unique integration questions of the ISPE were judged to have good content validity from experts and students, suggestive that integration, a most crucial element of clinical competence, while done in the mind of the student, can be practiced, learned and assessed.

    requirements, science and writing content knowledge, and classroom management. The findings indicated that the teachers were using writing in some of the ways supported by science and literacy education, but there were many areas of writing in science in which teachers could use support and education. This included more knowledge of authentic uses of writing in the science discipline, general writing-to-learn strategies, and assessment of student ideas and information in writing and not only writing skills. The teachers also needed support in better understanding the nature of science and scientific inquiry, and in how to negotiate the social and cultural factors that influence their pedagogical decisions in order to use writing in more authentic ways. This study suggests that teacher educators and administrators must learn more about how teachers understand their role as elementary teachers, as teachers of writing and science, and the environments within which they work in order to help them move toward authentic literacy and science writing practices.

    2015-01-01

    There are many challenges when an innovation (i.e., a program, process, or policy that is new to an organization) is actively introduced into an organization. One critical component for successful implementation is the organization’s readiness for the innovation. In this article, we propose a practical implementation science heuristic, abbreviated as R= MC2. We propose that organizational readiness involves: 1) the motivation to implement an innovation, 2) the general capacities of an organization, and 3) the innovation-specific capacities needed for a particular innovation. Each of these components can be assessed independently and be used formatively. The heuristic can be used by organizations to assess readiness to implement and by training and technical assistance providers to help build organizational readiness. We present an illustration of the heuristic by showing how behavioral health organizations differ in readiness to implement a peer specialist initiative. Implications for research and practice of organizational readiness are discussed. PMID:26668443

    Gurel, Derya Kaltakci

    2016-03-01

    In the scope of this study, pre-service science teachers (PSST) developed and carried out science demonstrations with everyday materials for elementary school students as a community service activity. 17 PSST enrolled in the community services practices course at Kocaeli University comprised the sample of the present study. Community service practices aim to develop consciousness of social responsibility and professional skills, as well as to gain awareness of social and community problems and find solutions for pre-service teachers. With this aim, each PSST developed five science demonstration activities and their brochures during a semester. At the end of the semester, a total of 85 demonstrations were carried out at public elementary schools, which are especially located in socioeconomically poor districts of Kocaeli, Turkey. In the present case study, the effect of developing and carrying out science demonstrations for elementary school students on six of the PSST' teaching practices on density and buoyancy concept was investigated. 30-minute interviews conducted with each PSST, videos recorded during their demonstration performances, brochures they prepared for their demonstration activities, and reflection papers were used as data collection tools of the study. The results showed that community service practices with science demonstrations had positive effects on PSST' science content knowledge and pedagogical content knowledge.

  6. The nature of science in science education: theories and practices

    Full Text Available The article is based on results of research carried out by the ESSA Group (Sociological Studies of the Classroom centred on the inclusion of the nature of science (metascience on science education. The results, based on analyses of various educational texts and contexts – curricula/syllabuses, textbooks and pedagogic practices – and of the relations between those texts/contexts, have in general shown a reduced presence and low conceptualization of metascience. The article starts by presenting the theoretical framework of the research of the ESSA Group which was focused on the introduction of the nature of science in science education. It is mostly based on Ziman’s conceptualization of metascience (1984, 2000 and on Bernstein’s theorization of production and reproduction of knowledge, particularly his model of pedagogic discourse (1990, 2000 and knowledge structures (1999. This is followed by the description of a pedagogical strategy, theoretically grounded, which explores the nature of science in the classroom context. The intention is to give an example of a strategy which privileges a high level learning for all students and which may contribute to a reflection about the inclusion of the nature of science on science education. Finally, considerations are made about the applicability of the strategy on the basis of previous theoretical and empirical arguments which sustain its use in the context of science education.

  7. Exploring alternative assessment strategies in science classrooms

    Full Text Available The knowledge children bring to the classroom or construct in the classroom may find expression in a variety of activities and is often not measurable with the traditional assessment instruments used in science classrooms. Different approaches to assessment are required to accommodate the various ways in which learners construct knowledge in social settings. In our research we attempted to determine the types of outcomes achieved in a Grade 6 classroom where alternative strategies such as interactive assessments were implemented. Analyses of these outcomes show that the learners learned much more than the tests indicate, although what they learnt was not necessarily science. The implications for assessment are clear: strategies that assess knowledge of science concepts, as well as assessment of outcomes other than science outcomes, are required if we wish to gain a holistic understanding of the learning that occurs in science classrooms.

  8. Formative assessment as a vehicle for changing classroom practice in a specific cultural context

    Chen, Jingping

    2015-09-01

    In this commentary, I interpret Xinying Yin and Gayle Ann Buck's collaborative action research from a social-cultural perspective. Classroom implementation of formative assessment is viewed as interaction between this assessment method and the local learning culture. I first identify Yin and Buck's definition of the formative assessment, and then analyze the role of formative assessment in the change of local learning culture. Based on the practice of Yin and Buck I emphasize the significance of their "bottom up" strategy to the teachers' epistemological change. I believe that this strategy may provide practicable solutions to current Chinese educational problems as well as a means for science educators to shift toward systematic professional development.

    2008-02-01

    In this study, the participants conceptualized and implemented an action research project that focused on the infusion of inquiry principles into a neglected science curriculum. Specific objectives were to find (a) What factors challenge and support the evolution of an action research community of practice? (b) How are teachers’ beliefs about science teaching and learning transformed? and (c) How does teachers’ knowledge of curriculum, instruction, assessment, and student learning change as a result of learning within a community of practice? In this instrumental case study (Stake 2000, In N. K. Denzin, & Y. S. Lincoln (Eds.), Handbook of qualitative research (pp. 435-454). Thousand Oaks, CA: Sage), a range of data collection sources and methods were adopted. Outcomes focus on how the design principles for cultivating a community of practice emerged in the action research group, as well as the types of teacher learning that occurred by engaging in action research.

    Ross, Annemarie D.

    As a Deaf individual, it is important to ensure the growth of the Deaf community as science-literate members of society. While many predecessors have contributed to the body of research in Deaf pedagogy, there is still much to be done in safeguarding Deaf learners' equitable access to science education. One area of concern is in narrowing the statistically significant gap in Climate Change knowledge between Deaf students' and Hearing students' at the Rochester Institute of Technology. It is within this topic that the writing-to-learn-science framework is practiced and Deaf students in the Laboratory Science Technology program at the National Technical Institute for the Deaf participate in a study to assess whether or not the use of writing-to-learn-science strategies help them become better scientists, writers and learners. In this study, the social constructivist framework (Vygotsky, 1987) is used to study the impact of the use of the Berland and Reiser (2009) argumentation framework, so that they write-to-learn-science through the steps of sense-making, articulation and persuasion.

  16. PORTAAL: A Classroom Observation Tool Assessing Evidence-Based Teaching Practices for Active Learning in Large Science, Technology, Engineering, and Mathematics Classes.

    Eddy, Sarah L; Converse, Mercedes; Wenderoth, Mary Pat

    2015-01-01

    There is extensive evidence that active learning works better than a completely passive lecture. Despite this evidence, adoption of these evidence-based teaching practices remains low. In this paper, we offer one tool to help faculty members implement active learning. This tool identifies 21 readily implemented elements that have been shown to increase student outcomes related to achievement, logic development, or other relevant learning goals with college-age students. Thus, this tool both clarifies the research-supported elements of best practices for instructor implementation of active learning in the classroom setting and measures instructors' alignment with these practices. We describe how we reviewed the discipline-based education research literature to identify best practices in active learning for adult learners in the classroom and used these results to develop an observation tool (Practical Observation Rubric To Assess Active Learning, or PORTAAL) that documents the extent to which instructors incorporate these practices into their classrooms. We then use PORTAAL to explore the classroom practices of 25 introductory biology instructors who employ some form of active learning. Overall, PORTAAL documents how well aligned classrooms are with research-supported best practices for active learning and provides specific feedback and guidance to instructors to allow them to identify what they do well and what could be improved. © 2015 S.

    Abstract This chapter surveys the status of educational systems and assessment practices across eight European countries that are part of the ASSIST-ME project. First, variations in country educational systems are examined to identify possible connections between systems and educational practices....... Such associations are useful both for understanding different existing assessment conditions as well as for providing possible pathways for change. Next, the chapter takes a closer look at teacher practices in these educational systems in order to identify the actual assessment practices of teachers in each country....... With these understandings of the systems and current uses of assessment, it is possible to identify affordances and challenges for improving assessment practices....

    2014-01-01

    Six years of UNESCO-World Technopolis Association workshops, held at various world cities and attended by government officials and scholars from nearly all the world’s countries, have resulted in a uniquely complete collection of reports on science park and science city projects in most of those countries. These reports, of which a selected few form chapters in this book, allow readers to compare knowledge-based development strategies, practices, and successes across countries. The chapters illustrate varying levels of cooperation across government, industry, and academic sectors in the respective projects – and the reasons and philosophies underlying this variation - and resulting differences in practices and results

    2017-08-01

    Trialogical learning, a collaborative and iterative knowledge creation process using real-life artefacts or problems, familiarizes students with working life environments and aims to teach skills required in the professional world. We target one of the major limitation factors for optimal trialogical learning in university settings, inefficient group work. We propose a course design combining effective group working practices with trialogical learning principles in life sciences. We assess the usability of our design in (a) a case study on crop science education and (b) a questionnaire for university teachers in life science fields. Our approach was considered useful and supportive of the learning process by all the participants in the case study: the students, the stakeholders and the facilitator. Correspondingly, a group of university teachers expressed that the trialogical approach and the involvement of stakeholders could promote efficient learning. In our case in life sciences, we identified the key issues in facilitating effective group work to be the design of meaningful tasks and the allowance of sufficient time to take action based on formative feedback. Even though trialogical courses can be time consuming, the experience of applying knowledge in real-life cases justifies using the approach, particularly for students just about to enter their professional careers.

  1. Reform-based science teaching: A mixed-methods approach to explaining variation in secondary science teacher practice

    Science.gov (United States)

    Jetty, Lauren E.

    The purpose of this two-phase, sequential explanatory mixed-methods study was to understand and explain the variation seen in secondary science teachers' enactment of reform-based instructional practices. Utilizing teacher socialization theory, this mixed-methods analysis was conducted to determine the relative influence of secondary science teachers' characteristics, backgrounds and experiences across their teacher development to explain the range of teaching practices exhibited by graduates from three reform-oriented teacher preparation programs. Data for this study were obtained from the Investigating the Meaningfulness of Preservice Programs Across the Continuum of Teaching (IMPPACT) Project, a multi-university, longitudinal study funded by NSF. In the first quantitative phase of the study, data for the sample (N=120) were collected from three surveys from the IMPPACT Project database. Hierarchical multiple regression analysis was used to examine the separate as well as the combined influence of factors such as teachers' personal and professional background characteristics, beliefs about reform-based science teaching, feelings of preparedness to teach science, school context, school culture and climate of professional learning, and influences of the policy environment on the teachers' use of reform-based instructional practices. Findings indicate three blocks of variables, professional background, beliefs/efficacy, and local school context added significant contribution to explaining nearly 38% of the variation in secondary science teachers' use of reform-based instructional practices. The five variables that significantly contributed to explaining variation in teachers' use of reform-based instructional practices in the full model were, university of teacher preparation, sense of preparation for teaching science, the quality of professional development, science content focused professional, and the perceived level of professional autonomy.

    Multiple representations have been widely used as a reasoning tool for understanding complex scientific concepts. Thus this study attempted to investigate the current practice of using multiple representations on Year 4 science classrooms in terms of modes and levels which appear in curriculum documents, teaching plans, tasks and assessments, teaching practices, and students' behaviors. Indeed, documentary analysis, classroom observation, and interview were used as the data collection methods. First of all, Year 4 science documents were analyzed. Then classroom observation was used as a collecting method to seek what actually happen in the classroom. Finally, in-depth interviews were used to gather more information and obtain meaningful data. The finding reveals that many modes of verbal, visual, and tactile representations within three levels of representations are posed in Year 4 documents. Moreover, according to classroom observations and interviews, there are three main points of applying multiple representations into classrooms. First of all, various modes of representations were used, however, a huge number of them did not come together with the levels. The levels of representations, secondly, macroscopic and cellular levels were introduced into all classrooms while symbolic level was provided only in some classrooms. Finally, the connection of modes and levels pointed out that modes of representations were used without the considerations on the levels of them. So, it seems to be that teaching practice did not meet the aims of curriculum. Therefore, these issues were being considered in order to organize and design the further science lessons.

    1994-12-31

    A research project is described which has investigated the relationship between science-based knowledge of energy efficient building and practical energy saving action. A comparison of government funded research and development programmes has shown how knowledge of energy efficient building technology has been developed and applied. Beliefs about the nature of social change which underly these technical programmes have been revealed by an analysis of the theory and practice of technology transfer. An examination of three specific energy saving action contexts illustrates the tensions between standardised scientific knowledge and the diverse social and organisational situations in which technical expertise is applied. The report raises questions about the interaction of natural and social science and environmental policy. (UK)

    2017-07-01

    Numerous case studies suggest that integrating art and science education could engage students with creative projects and encourage students to express science in multitude of ways. However, little is known about art integration practices in everyday science teaching. With a qualitative e-survey, this study explores the art integration of science teachers (n = 66). A pedagogical model for science teachers' art integration emerged from a qualitative content analysis conducted on examples of art integration. In the model, art integration is characterised as integration through content and activities. Whilst the links in the content were facilitated either directly between concepts and ideas or indirectly through themes or artefacts, the integration through activity often connected an activity in one domain and a concept, idea or artefact in the other domain with the exception of some activities that could belong to both domains. Moreover, the examples of art integration in everyday classroom did not include expression of emotions often associated with art. In addition, quantitative part of the survey confirmed that integration is infrequent in all mapped areas. The findings of this study have implications for science teacher education that should offer opportunities for more consistent art integration.

  7. Towards science educational spaces as dynamic and coauthored communities of practice

    Dhingra, Koshi

    2008-04-01

    In this essay review, four studies around the themes of identity and globalization are summarized and analyzed. The researchers' perspectives are generally grounded in Brown and Campione's ideas on situated knowledge ( Classroom lessons: Integrating cognitive theory and classroom practice (pp. 229-270). Cambridge: The MIT Press/Bradford Books, 1994) and Lave and Wenger's definition of learning as an activity fostered through participation in communities of practice ( Situated learning. Legitimate peripheral participation. Cambridge: University of Cambridge Press, 1991). Questions about the goals of science education spaces, the nature of globalization in relation to practices in schools, the role of identities-in-practice in relation to participation in communities of practice such as classrooms are explored. Recommendations for key design features in effective science educational spaces, based upon the findings presented in the collection of four studies, are offered. School, it is suggested here, functions best as a clearing house for the myriad science-related stories student participants generate in their various communities of practice (e.g., within popular culture, family, community, informal educational sites). In this way, school has the potential to construct bridges between multiple student experiences and identities-in-practice.

  8. Explainers' development of science-learner identities through participation in a community of practice

    Science.gov (United States)

    Richardson, Anne E.

    The urgent environmental issues of today require science-literate adults to engage in business and political decisions to create solutions. Despite the need, few adults have the knowledge and skills of science literacy. This doctoral dissertation is an analytical case study examining the science-learner identity development of Exploratorium Field Trip Explainers. Located in San Francisco, CA, the Exploratorium is a museum of science, art, and human perception dedicated to nurturing curiosity and exploration. Data collected included semi-structured interviews with sixteen former Field Trip Explainers, participant observation of the current Field Trip Explainer Program, and review of relevant documentation. Data analysis employed constant comparative analysis, guided by the communities of practice theoretical framework (Wenger, 1998) and the National Research Council's (2009) Six Strands of Science Learning. Findings of this research indicate that Exploratorium Field Trip Explainers participate in a community of practice made up of a diverse group of people that values curiosity and openness to multiple ways of learning. Many participants entered the Field Trip Explainer Program with an understanding of science learning as a rigid process reserved for a select group of people; through participation in the Field Trip Explainer community of practice, participants developed an understanding of science learning as accessible and a part of everyday life. The findings of this case study have implications for research, theory, and practice in informal adult science learning, access of non-dominant groups to science learning, and adult workplace learning in communities of practice.

  9. A conceptual framework for understanding the perspectives on the causes of the science-practice gap in ecology and conservation.

    Applying scientific knowledge to confront societal challenges is a difficult task, an issue known as the science-practice gap. In Ecology and Conservation, scientific evidence has been seldom used directly to support decision-making, despite calls for an increasing role of ecological science in developing solutions for a sustainable future. To date, multiple causes of the science-practice gap and diverse approaches to link science and practice in Ecology and Conservation have been proposed. To foster a transparent debate and broaden our understanding of the difficulties of using scientific knowledge, we reviewed the perceived causes of the science-practice gap, aiming to: (i) identify the perspectives of ecologists and conservation scientists on this problem, (ii) evaluate the predominance of these perspectives over time and across journals, and (iii) assess them in light of disciplines studying the role of science in decision-making. We based our review on 1563 sentences describing causes of the science-practice gap extracted from 122 articles and on discussions with eight scientists on how to classify these sentences. The resulting process-based framework describes three distinct perspectives on the relevant processes, knowledge and actors in the science-practice interface. The most common perspective assumes only scientific knowledge should support practice, perceiving a one-way knowledge flow from science to practice and recognizing flaws in knowledge generation, communication, and/or use. The second assumes that both scientists and decision-makers should contribute to support practice, perceiving a two-way knowledge flow between science and practice through joint knowledge-production/integration processes, which, for several reasons, are perceived to occur infrequently. The last perspective was very rare, and assumes scientists should put their results into practice, but they rarely do. Some causes (e.g. cultural differences between scientists and decision

    2017-12-12

    This paper evaluates current stakeholder involvement (SI) practices in science through a web-based survey among scholars and researchers engaged in sustainability or transition research. It substantiates previous conceptual work with evidence from practice by building on four ideal types of SI in science. The results give an interesting overview of the varied landscape of SI in sustainability science, ranging from the kinds of topics scientists work on with stakeholders, over scientific trade-offs that arise in the field, to improvements scientists wish for. Furthermore, the authors describe a discrepancy between scientists' ideals and practices when working with stakeholders. On the conceptual level, the data reflect that the democratic type of SI is the predominant one concerning questions on the understanding of science, the main goal, the stage of involvement in the research process, and the science-policy interface. The fact that respondents expressed agreement to several types shows they are guided by multiple and partly conflicting ideals when working with stakeholders. We thus conclude that more conceptual exchange between practitioners, as well as more qualitative research on the concepts behind practices, is needed to better understand the stakeholder-scientist nexus.

  13. Students' Views About Secondary School Science Lessons: The Role of Practical Work

    Science.gov (United States)

    Toplis, Rob

    2012-06-01

    This paper reports an interpretive study that sought students' views about the role that practical work plays in their school science lessons. Twenty-nine students aged between 13 and 16 years were selected from three secondary schools in England. Data were collected from initial lesson observations and in-depth interviews in order to explore students' views about practical work. The findings suggest that students have three main reasons why practical work is important in their school science lessons: for interest and activity, including social and personal features such as participation and autonomy; as an alternative to other forms of science teaching involving a pedagogy of transmission, and as a way of learning, including memorizing and recall. The findings are discussed in the context of a critical view of previous work on the role of practical work, work on attitudes to science and on the student voice. The paper concludes that practical work is seen to provide opportunities for students to engage with and influence their own learning but that learning with practical work remains a complex issue that needs further research and evaluation about its use, effectiveness and of the role of scientific inquiry as a component of practical activity.

  14. The paradox of un/making science people: practicing ethico-political hesitations in science education

    Science.gov (United States)

    Wallace, Maria F. G.

    2018-03-01

    Over the years neoliberal ideology and discourse have become intricately connected to making science people. Science educators work within a complicated paradox where they are obligated to meet neoliberal demands that reinscribe dominant, hegemonic assumptions for producing a scientific workforce. Whether it is the discourse of school science, processes of being a scientist, or definitions of science particular subjects are made intelligible as others are made unintelligible. This paper resides within the messy entanglements of feminist poststructural and new materialist perspectives to provoke spaces where science educators might enact ethicopolitical hesitations. By turning to and living in theory, the un/making of certain kinds of science people reveals material effects and affects. Practicing ethicopolitical hesitations prompt science educators to consider beginning their work from ontological assumptions that begin with abundance rather than lack.

  15. Teaching Climate Social Science and Its Practices: A Two-Pronged Approach to Climate Literacy

    Science.gov (United States)

    Shwom, R.; Isenhour, C.; McCright, A.; Robinson, J.; Jordan, R.

    2014-12-01

    The Essential Principles of Climate Science Literacy states that a climate-literate individual can: "understand the essential principles of Earth's climate system, assess scientifically credible information about climate change, communicate about climate and climate change in a meaningful way, and make informed and responsible decisions with regard to actions that may affect climate." We argue that further integration of the social science dimensions of climate change will advance the climate literacy goals of communication and responsible actions. The underlying rationale for this argues: 1) teaching the habits of mind and scientific practices that have synergies across the social and natural sciences can strengthen students ability to understand and assess science in general and that 2) understanding the empirical research on the social, political, and economic processes (including climate science itself) that are part of the climate system is an important step for enabling effective action and communication. For example, while climate literacy has often identified the public's faulty mental models of climate processes as a partial explanation of complacency, emerging research suggests that the public's mental models of the social world are equally or more important in leading to informed and responsible climate decisions. Building student's ability to think across the social and natural sciences by understanding "how we know what we know" through the sciences and a scientific understanding of the social world allows us to achieve climate literacy goals more systematically and completely. To enable this integration we first identify the robust social science insights for the climate science literacy principles that involve social systems. We then briefly identify significant social science contributions to climate science literacy that do not clearly fit within the seven climate literacy principles but arguably could advance climate literacy goals. We conclude

    2014-12-01

    Modern climate science assessments now have a history of nearly a quarter-century. This experience, together with important advances in relevant social sciences, has greatly improved our ability to communicate climate science effectively. As a result, the Third National Climate Assessment (NCA) was designed to be truly accessible and useful to all its intended audiences, while still being comprehensive and scientifically accurate. At a time when meeting the challenge of climate change is increasingly recognized as an urgent national and global priority, the NCA is proving to be valuable to decision-makers, the media, and the public. In producing this latest NCA, a communication perspective was an important part of the process from the beginning, rather than an afterthought as has often been the case with scientific reports. Lessons learned from past projects and science communications research fed into developing the communication strategy for the Third NCA. A team of editors and graphic designers worked closely with the authors on language, graphics, and photographs throughout the development of the report, Highlights document, and other products. A web design team helped bring the report to life online. There were also innovations in outreach, including a network of organizations intended to extend the reach of the assessment by engaging stakeholders throughout the process. Professional slide set development and media training were part of the preparation for the report's release. The launch of the NCA in May 2014 saw widespread and ongoing media coverage, continued references to the NCA by decision-makers, and praise from many quarters for its excellence in making complex science clear and accessible. This NCA is a professionally crafted report that exemplifies best practices in 21st century communications.

    In recent years professional societies have been undergoing fundamental restructuring brought on by extensive technological change and rapid evolution of geospatial science. Almost all professional communities have been affected. Communities are embracing digital techniques, modern equipment, software and new technological solutions at a staggering pace. In this situation, when planning financial investments and intellectual resource management, it is crucial to have a clear understanding of those trends that will be in great demand in 3-7 years. This paper reviews current scientific and practical activities of such non-governmental international organizations as International Federation of Surveyors, International Cartographic Association, and International Society for Photogrammetry and Remote Sensing, analyzes and groups most relevant topics brought up at their scientific events, forecasts most probable research and practical trends in geospatial sciences, outlines topmost leading countries and emerging markets for further detailed analysis of their activities, types of scientific cooperation and joint implementation projects.

  20. Preservice Teachers and Their Preconceptions of the NGSS Science and Engineering Practice of Developing and Using Models in Elementary Science Education

    Science.gov (United States)

    Burks, Lizette A.

    The science and engineering practice of developing and using models is a new science practice identified to achieve the vision of three-dimensional teaching and learning and as such should be an important new component of teacher preparation programs (NRC, 2012). Developing and using models is a high-leverage practice in teacher preparation because of the use of discourse in its implementation that is also used in other practices utilized within the NGSS (NGSS Lead States, 2013) science classroom. Additionally, the overlap between the other seven identified NGSS (NGSS Lead States, 2013) practices and the development and use of models along with the use of models represented in two of the overall three dimensions of the new vision for science education (NRC, 2012) contribute to its high leverage nature. The intent of this study was to examine elementary science preservice teachers' understandings and preconceptions about the practice of developing and using models. This study provides important information for teacher preparation to use this high-leverage practice. The study examined preservice teachers' preconceptions about the practice of developing and using models including discourse patterns the preservice teachers identified as being critical to the success of this practice in the classroom. Data were gathered through a written survey in which preservice teachers described their initial understanding about different components of modeling instruction. A video was used to elicit their initial understandings about certain components of modeling instruction. A sample of the preservice teachers were interviewed to elaborate on their responses to the survey. The results of the study indicated that when preservice teachers initially described how this practice might look in the classroom, only two of the six categories described in A Science Framework for K-12 Science Education (NRC, 2012) for this practice were described by most participants. Of those two

    The advancement of implementation science is dependent on identifying assessment strategies that can address implementation and clinical outcome variables in ways that are valid, relevant to stakeholders, and scalable. This paper presents a measurement agenda for implementation science that integrates the previously disparate assessment traditions of idiographic and nomothetic approaches. Although idiographic and nomothetic approaches are both used in implementation science, a review of the literature on this topic suggests that their selection can be indiscriminate, driven by convenience, and not explicitly tied to research study design. As a result, they are not typically combined deliberately or effectively. Thoughtful integration may simultaneously enhance both the rigor and relevance of assessments across multiple levels within health service systems. Background on nomothetic and idiographic assessment is provided as well as their potential to support research in implementation science. Drawing from an existing framework, seven structures (of various sequencing and weighting options) and five functions (Convergence, Complementarity, Expansion, Development, Sampling) for integrating conceptually distinct research methods are articulated as they apply to the deliberate, design-driven integration of nomothetic and idiographic assessment approaches. Specific examples and practical guidance are provided to inform research consistent with this framework. Selection and integration of idiographic and nomothetic assessments for implementation science research designs can be improved. The current paper argues for the deliberate application of a clear framework to improve the rigor and relevance of contemporary assessment strategies.

Today, more than 40 so-called pressure ulcer risk assessment scales are available but still there is an ongoing debate about their usefulness. From a measurement point of view pressure ulcer (PU risk assessment scales have serious limitations. Empirical evidence supporting the validity of PU risk assessment scale scores is weak and obtained scores contain varying amounts of measurement error. The concept of pressure ulcer risk is strongly related to the general health status and severity of illness. A clinical impact due do the application of these scales could also not be demonstrated. It is questionable whether completion of standardized pressure ulcer risk scales in clinical practice is really needed.Keywords: Braden pressure ulcer, prevention, risk assessment, nursing assessment, predictive value, clinical effectiveness, review

Inpatients admitted January 2012 to July 2013. Implementation of two PU best practices were targeted: (1) completing a comprehensive PU risk assessment and individualized interprofessional PU prevention plan (PUPP); and (2) providing patient education for PU prevention; as part of the pan-Canadian SCI Knowledge Mobilization Network. At our center, the SCI Pressure Ulcer Scale replaced the Braden risk assessment scale and an interprofessional PUPP form was implemented. Comprehensive educational programing existed, so efforts focused on improving documentation. Implementation science frameworks provided structure for a systematic approach to best practice implementation (BPI): (1) site implementation team, (2) implementation drivers, (3) stages of implementation, and (4) improvement cycles. Strategies were developed to address key implementation drivers (staff competency, organizational supports, and leadership) through the four stages of implementation: exploration, installation, initial implementation, and full implementation. Improvement cycles were used to address BPI challenges. Implementation processes (e.g. staff training) and BPI outcomes (completion rates). Following BPI, risk assessment completion rates improved from 29 to 82%. The PUPP completion rate was 89%. PU education was documented for 45% of patients (vs. 21% pre-implementation). Implementation science provided a framework and effective tools for successful pressure ulcer BPI in SCI rehabilitation. Ongoing improvement cycles will target timeliness of tool completion and documentation of patient education.

  9. Exploring reforms while learning to teach science: Facilitating exploration of theory-practice relationships in a teacher education study group

    Science.gov (United States)

    Foster, Jacob G.

    This dissertation inserts a new view into an old problem in teacher education. The study explores the theory-practice gap, the large distance between what preservice science teachers experience in schools, are able to enact, and are told they should hold themselves to in their practice. It does so by narrowing the focus of analysis to a secondary science study group and examining how the facilitator uses sociocultural constructivism to promote discussion. The analysis surfaces key communicative moves made by the facilitator and preservice teachers that yield fruitful discussion of theory-practice relationships. Additionally, the study's use of discourse analysis as a methodology and intertextuality as a conceptual framework opens new directions for applied sociolinguistic research and scholarship in science teacher education. Findings from the study focus on what was discussed and how explorations of theory-practice relationships were facilitated. Preservice teachers in the study group engaged in meaningful conversations about constructivist theory and its application to their students and teaching of science. They discussed many science education topics such as planning science lessons that actively engage students, assessment of content understanding, and management of content-based activities. Discussions of broader science education goals, including implementation of inquiry or development of collaborative communities, were not promoted. Examination of the facilitation illuminates a number of strategies found to be helpful in supporting these explorations. This study shows that facilitation can successfully support preservice teachers to construct understanding of social constructivist assumptions underlying the National Science Education Standards (NSES), as well as a few components of the Standards themselves. The focus on the underlying assumptions suggests that science teacher education should focus on these so that preservice teachers can build a strong

    Despite many scholars' recommendations, science is often avoided during early childhood education. Among the reasons provided by early childhood teachers for the exclusion of science from their daily routines included science anxiety, low self-efficacy with respect to teaching science, lack of experience participating in science activities as students, or the notion that literacy and language are more important during the early years. In minority populations the problem is even greater due to identification of science with the `culture of. This article presents results from Ah Neen Dush, a sustained and transformative professional development program for Head Start teachers on an American Indian Reservation. The goal of the program is to support early childhood teachers in developing inquiry-based and culturally-relevant teaching practices. Through analysis of teachers' classroom practices, surveys and interviews, we explore changes in teachers' attitudes toward science and inquiry-based practices. Classroom observations were conducted using CLASS (Classroom assessment Scoring System), a tool used to evaluate the quality of classroom interactions. After 1 year of professional development teachers' attitudes were found to improve and after 2 years teachers classroom practices were more inquiry-based with statistically significant increases in CLASS observation scores.

  12. Assessment practices of third- and fifth-grade science teachers: A comparison to the style/format, process, and content of Ohio's proficiency tests

    Science.gov (United States)

    Janson, David C.

    This descriptive study is addressed to policy-makers, textbook publisher, teachers, principals, and curriculum directors. It compares the assessment practices of ten elementary teachers over a period of 11 weeks with Ohio's fourth and sixth grade science Proficiency Tests. Results show that the teachers' assessment practices were not aligned with Ohio's Proficiency Test. The tests used in the participants' classroom contained a disproportionate number of items characterized as low-level in terms of their cognitive function. Classroom test items generally fell into three categories---true/false, completion, and matching. The remaining items were predominantly low-level multiple-choice items requiring simple recall of information. The teachers in this study showed a heavy reliance on the packaged assessments that accompanied their adopted textbook series with little use of teacher-designed instruments. This differs from the findings of previous researchers who reported that most teacher assessments were done with teacher-made tests. The lack of alignment between classroom tests and Ohio's Proficiency Test is a concern because previous researchers and the teachers in this study believe that aligning classroom tests with high-stakes assessment improves student performance. Other research shows teachers teach what they test suggesting that the curriculum would be better aligned with State expectations if classroom tests were more in line with the proficiency tests. This study found that textbooks and their assessment packages are not aligned to most state standards and that teachers need help developing better assessments. The results of this study suggest directions school administrators might take to facilitate inservice training for current teachers and could be helpful to textbook publishers as well as educators serving on adoption committees. Since high-stakes testing of students in the nation's public schools and school accountability seem destined to remain a

  13. Meaningful Engagement in Scientific Practices: How Classroom Communities Develop Authentic Epistemologies for Science

    Science.gov (United States)

    Krist, Christina Rae

    Recent reforms in science education, based on decades of learning research, emphasize engaging students in science and engineering practices as the means to develop and refine disciplinary ideas. These reforms advocate an epistemic shift in how school science is done: from students learning about science ideas to students figuring out core science ideas. This shift is challenging to implement: how do we bring the goals and practices of a discipline into classroom communities in meaningful ways that go beyond simply following rote scientific procedures? In this dissertation, I investigate how classroom communities learn to engage meaningfully in scientific practices, characterizing their engagement as a process of epistemic learning. I take a situated perspective that defines learning as shifts in how members engage in communities of practice. I examine students' epistemic learning as a function of their participation in a classroom community of scientific practice along two dimensions: what they do, or the practical epistemic heuristics they use to guide how they build knowledge; and who they are, or how ownership and authorship of ideas is negotiated and affectively marked through interaction. I focus on a cohort of students as they move from 6th to 8 th grade. I analyze three science units, one from each grade level, to look at the epistemic heuristics implicit in student and teacher talk and how the use of those heuristics shifts over time. In addition, I examine one anomalous 8th grade class to look at how students and the teacher position themselves and each other with respect to the ideas in their classroom and how that positioning supports epistemic learning. Taken together, these analyses demonstrate how students' engagement in scientific practices evolves in terms of what they do and who they are in relation to the knowledge and ideas in their classroom over time. I propose a model for epistemic learning that articulates how classroom communities develop

Bush report Science: the Endless Frontier (1945 as its conceptual basis, which remains the cornerstone of the American science policy. The authors point out decentralization as the key trait of this structure, which reveals itself in the absence of a unitary centre with a mission to formulate and implement science policy and high level of dissemination of self-government practices supported by a wide range of government agencies. This configuration determines the special position, occupied by the universities as universal research establishments possessing flexibility in cooperation with state agencies and private sector.

  15. Reasons and resources for being explicit about the practices of science

    Science.gov (United States)

    Egger, A. E.

    2015-12-01

    The Next Generation Science Standards (NGSS) promote a fundamental shift in the way science is taught. The new focus is on three-dimensional learning, which brings science and engineering practices together with disciplinary core ideas and cross-cutting concepts. A key component is performance expectations rather than bullet lists of content that students should know. One of the stated goals is that "all students should have sufficient knowledge of science and engineering to engage in public discussions on related issues." While the NGSS were developed for K-12, college instructors benefit from familiarity with them in two critical ways: first, they provide a research-based and clearly articulated approach to three-dimensional learning that applies across the grade spectrum, and second, future K-12 teachers are sitting in their college-level science courses, and awareness of the skills those future teachers need can help direct course design. More specifically, while most college-level science courses make use of the science and engineering practices described in the NGSS, few offer explicit instruction in them or how they intertwine with disciplinary core ideas and cross-cutting concepts. Yet this explicit instruction is critical to building scientific literacy in future teachers—and all students. Many textbooks and laboratory courses limit a discussion of the process of science to one chapter or exercise, and expect students to be able to apply those concepts. In contrast, new resources from Visionlearning (http://www.visionlearning.com), InTeGrate (http://serc.carleton.edu/integrate), and other projects hosted at the Science Education Resource Center (http://serc.carleton.edu) were developed with explicit and pervasive integration of the nature and practices of science in mind. These freely available, classroom-tested and reviewed resources support instructors in introductory/general education courses as well as teacher preparation and more advanced courses.

    This article is the first to describe the discoursal construction of an adolescent community of practice (CoP) in a non-school setting. CoPs can provide optimal learning environments. The adolescent community centered around science journalism and positioned itself dichotomously in relationship to school literacy practices. The analysis focuses on recordings from a panel-style research interview from an early implementation of the Science Literacy Through Science Journalism (SciJourn) project. Researchers trained high school students participating in a youth development program to write science news articles. Students engaged in the authentic practices of professional science journalists, received feedback from a professional editor, and submitted articles for publication. I used a fine-grained critical discourse analysis of genre, discourse, and style to analyze student responses about differences between writing in SciJourn and in school. Students described themselves as agentic in SciJourn and passive in school, using an academic writing discourse of deficit to describe schooling experiences. They affiliated with and defined a SciJourn CoP, constructing positive journalistic identities therein. Educators are encouraged to develop similar CoPs. The discursive features presented may be used to monitor the development of communities of practice in a variety of settings.

    Benedict-Chambers, Amanda; Kademian, Sylvie M.; Davis, Elizabeth A.; Palincsar, Annemarie Sullivan

    2017-10-01

    Science education reforms articulate a vision of ambitious science teaching where teachers engage students in sensemaking discussions and emphasise the integration of scientific practices with science content. Learning to teach in this way is complex, and there are few examples of sensemaking discussions in schools where textbook lessons and teacher-directed discussions are the norm. The purpose of this study was to characterise the questioning practices of an experienced teacher who taught a curricular unit enhanced with educative features that emphasised students' engagement in scientific practices integrated with science content. Analyses indicated the teacher asked four types of questions: explication questions, explanation questions, science concept questions, and scientific practice questions, and she used three questioning patterns including: (1) focusing students on scientific practices, which involved a sequence of questions to turn students back to the scientific practice; (2) supporting students in naming observed phenomena, which involved a sequence of questions to help students use scientific language; and (3) guiding students in sensemaking, which involved a sequence of questions to help students learn about scientific practices, describe evidence, and develop explanations. Although many of the discussions in this study were not yet student-centred, they provide an image of a teacher asking specific questions that move students towards reform-oriented instruction. Implications for classroom practice are discussed and recommendations for future research are provided.

    Examination of Saudi Arabian educational practices is scarce, but increasingly important, especially in light of the country's pace in worldwide mathematics and science rankings. The purpose of the study is to understand and evaluate parental influence on male children's science education achievements in Saudi Arabia. Parental level of education and participant's choice of science major were used to identify groups for the purpose of data analysis. Data were gathered using five independent variables concerning parental educational practices (attitude, involvement, autonomy support, structure and control) and the dependent variable of science scores in high school. The sample consisted of 338 participants and was arbitrarily drawn from the science-based colleges (medical, engineering, and natural science) at Jazan University in Saudi Arabia. The data were tested using Pearson's analysis, backward multiple regression, one way ANOVA and independent t-test. The findings of the study reveal significant correlations for all five of the variables. Multiple regressions revealed that all five of the parents' educational practices indicators combined together could explain 19% of the variance in science scores and parental attitude toward science and educational involvement combined accounted for more than 18% of the variance. Analysis indicates that no significant difference is attributable to parental involvement and educational level. This finding is important because it indicates that, in Saudi Arabia, results are not consistent with research in Western or other Asian contexts.

    The purpose for conducting this qualitative study was to explore best practices of exemplary standards-based science programs and instructional leadership practices in a charter high school and in a traditional high school. The focus of this study included how twelve participants aligned practices to National Science Education Standards to describe their science programs and science instructional practices. This study used a multi-site case study qualitative design. Data were obtained through a review of literature, interviews, observations, review of educational documents, and researcher's notes collected in a field log. The methodology used was a multi-site case study because of the potential, through cross analysis, for providing greater explanation of the findings in the study (Merriam, 1988). This study discovered six characteristics about the two high school's science programs that enhance the literature found in the National Science Education Standards; (a) Culture of expectations for learning-In exemplary science programs teachers are familiar with a wide range of curricula. They have the ability to examine critically and select activities to use with their students to promote the understanding of science; (b) Culture of varied experiences-In exemplary science programs students are provided different paths to learning, which help students, take in information and make sense of concepts and skills that are set forth by the standards; (c) Culture of continuous feedback-In exemplary science programs teachers and students work together to engage students in ongoing assessments of their work and that of others as prescribed in the standards; (d) Culture of Observations-In exemplary science programs students, teachers, and principals reflect on classroom instructional practices; teachers receive ongoing evaluations about their teaching and apply feedback towards improving practices as outlined in the standards; (e) Culture of continuous learning-In exemplary

    2008-12-01

    Nursing is often described from the point of view of either the natural or the human sciences. In contrast to this, the value foundation in Interactional nursing practice is understood from the point of view of the natural sciences as well as that of the human and social sciences. This article presents many-faceted practice-theory of nursing, which is situated in the dynamic field between these three sciences. The focus of the theory is on interaction and practice resulting in a caring practice. Here practice is based on Taylor's and MacIntyre's interpretation of this concept. Action in nursing is based on Habermas' three varied modes of action seen in the light of an understanding of the world as a system world and a life world. Nursing as an interactional practice-theory is presented with examples of interpretative nursing science, seen in the ethical action-oriented, socio-cultural framework of Taylor and Habermas. It is concluded that phenomenologic and socio-cultural research into caring practice as well as an in-depth, comprehensive interpretation of nursing practice are both highly suited to forming the fundamental theoretical framework in nursing, here seen as an interpretative nursing science. Finally, a comparison is drawn between Interactional nursing practice and Benner's theory of nursing practice.

    With the goal of helping teacher candidates become well-started beginners, it is important that methods courses in teacher education programs focus on high-leverage practices. Using responsive teaching practices, specifically eliciting, identifying, interpreting, and responding to students' science ideas (i.e., formative assessment), can be used to support all students in learning science successfully. This study follows seven secondary science teacher candidates in a yearlong practice-based methods course. Course assignments (i.e., plans for and reflections on teaching) as well as teaching videos were analyzed using a recursive qualitative approach. In this paper, we present themes and patterns in teacher candidates' abilities to elicit, identify, interpret, and respond to students' ideas. Specifically, we found that those teacher candidates who grew in the ways in which they elicited students' ideas from fall to spring were also those who were able to adopt a more balanced reflection approach (considering both teacher and student moves). However, we found that even the teacher candidates who grew in these practices did not move toward seeing students' ideas as nuanced; rather, they saw students' ideas in a dichotomous fashion: right or wrong. We discuss implications for teacher preparation, specifically for how to promote productive reflection and tools for better understanding students' ideas.

    To describe the development of an integrated pain and palliative care course and to investigate the long-term effectiveness of the course during doctor of pharmacy (PharmD) students' advanced pharmacy practice experiences (APPEs) and in their practice after graduation. Roseman University College of Pharmacy faculty developed a 3-week elective course in pain and palliative care by integrating relevant clinical and pharmaceutical sciences. Instructional strategies included lectures, team and individual activities, case studies, and student presentations. Students who participated in the course in 2010 and 2011 were surveyed anonymously to gain their perception about the class as well as the utility of the course during their APPEs and in their everyday practice. Traditional and nontraditional assessment of students confirmed that the learning outcomes objectives were achieved. Students taking the integrated course on pain management and palliative care achieved mastery of the learning outcome objectives. Surveys of students and practicing pharmacists who completed the course showed that the learning experience as well as retention was improved with the integrated mode of teaching. Integrating basic and clinical sciences in therapeutic courses is an effective learning strategy.

    The main purpose of this study was to explore the factors mediating the translation of second grade teachers' nature of science (NOS) views into classroom practice after completing a graduate level NOS course. Four second grade in-service elementary teachers comprised the sample of this study. Data were collected from several sources during the course of this study. The primary data sources were (a) assessment of the elementary teachers' NOS views before and after the graduate level NOS course using the Views of Nature of Science Questionnaire Version B (VNOS-B) (Lederman et al., 2002) coupled with interviews, and (b) a classroom observation and videotaped recording of the elementary teachers' best NOS lessons coupled with interview. We identified three distinct but related factors that mediated the translation of NOS views into classroom practice: the teachers' perspectives about the developmental appropriateness of the NOS aspect, the teachers' selection of target NOS aspects, and the relative importance placed by teachers on each NOS aspect.

    Salame, Hania Moussa

    The purpose of the current study was to examine the effects of adapting the instructional congruence model on the English Language Learners' (ELL) attitudes and achievement in science. Changes in teacher's views and practices were documented. The mixed-method approach was adapted. Data sources were the "Attitude Towards Science" survey, VNOS-C questionnaire, Luykx and Lee (2007) observational instrument, Gee (1997) discussion categories, video recordings, and pre- and post-tests. A science teacher and a class of 24 ELL female students in a charter school participated in this research. The results of this study indicated that student achievement increased significantly and students' attitudes improved in all contexts. At the conclusion of the study, all teacher's views on NOS were reported to be informed, teacher's practices were rated higher, and different classroom interactions increased significantly. The instructional congruence model in science education has been successful in reaching different learners, improving students' attitudes and achievement in science and enhancing teacher's views and practices. This model has significant potential for meeting the challenging goals of reformed science education.

  11. Assessing the Impact of Lesson Study on the Teaching Practice of Middle School Science Teachers

    Science.gov (United States)

    Grove, Michael C.

    Despite wave after wave of educational reform in the United States our students continue to lag behind their peers in other industrialized countries on virtually all measures of academic achievement. Effective professional development (PD) is seen as a key to improving instructional practice and therefore student learning, but traditional forms of PD have been wholly unsuccessful in changing teaching practice. Over the last two decades an emerging body of research has identified some key features of effective PD that seem to create meaningful change and improvement in instructional practice. Some of this research highlights the promise of adapting Japanese lesson study (LS) to the American context as a means of incrementally improving instruction. Much of the existing research around LS is descriptive in nature and offers little insight into if and how participation in LS impacts subsequent instructional practice. This study utilized case study methodology to examine the instructional practice of one group of four middle school science teachers before, during, and after participation in LS. The study attempted to identify specific learning outcomes of a LS process, to identify influences on teacher learning during LS, and to identify subsequent changes in the instructional practice of participants resulting from participation in LS. Key findings from the study include significant teacher learning derived from the LS process, the identification of influences that enhanced or inhibited teacher learning, and clear evidence that participants successfully integrated learning from the LS into subsequent instructional practice. Learning outcomes included deepening of subject matter knowledge, increased understanding of student thinking and abilities, clarity of expectations for student performance, recognition of the ineffectiveness of past instructional practice, specific instructional strategies, shared student learning goals, and an increased commitment to future

    In this paper we examine some fundamental epistemological issues in building theory for applied management science, by which we mean theory that can be usefully applied in a scientific approach to management research and practice. We first define and distinguish “grand theory” from “mid......-range theory” in the social and management sciences. We then elaborate and contrast epistemologies for (i) building “grand theory” intended to be applicable to all cases and contexts, and (ii) building “mid-range theory” intended to apply to specific kinds of contexts. We illustrate the epistemological...... challenges in building grand theory in management science by considering important differences in the abilities of two “grand theories” in strategic management – industry structure theory and firm resources theory – to support development of conceptually consistent models and propositions for empirical...

  13. The effects of formative assessment on student self-regulation, motivational beliefs, and achievement in elementary science

    -regulation for students in specific instructional services subgroups (i.e., gifted, regular education, special education, and ESL). For example, high achieving students reported higher levels of self-regulatory learning behavior than other fifth grade students. Findings suggested that elementary science instruction that includes classroom applications of formative assessment with reflection may provide support for science learning and the development of self-regulatory learning behavior. However, widespread implementation of this practice in elementary science classrooms represents significant challenges for today's educators, due to time limitations and increasing accountability pressures in our nation's schools.

    2018-02-01

    Employing achievement goal theory (Ames Journal of Educational psychology, 84(3), 261-271, 1992), we explored science teachers' instruction and its relation to students' motivation for science learning and school culture. Based on the TARGETS framework (Patrick et al. The Elementary School Journal, 102(1), 35-58, 2001) and using data from 95 teachers, we developed a self-report survey assessing science teachers' usage of practices that emphasize mastery goals. We then used this survey and hierarchical linear modeling (HLM) analyses to study the relations between 35 science teachers' mastery goals in each of the TARGETS dimensions, the decline in their grade-level 5-8 students' ( N = 1.356) classroom and continuing motivation for science learning, and their schools' mastery goal structure. The findings suggest that adolescents' declining motivation for science learning results in part from a decreasing emphasis on mastery goals by schools and science teachers. Practices that relate to the nature of tasks and to student autonomy emerged as most strongly associated with adolescents' motivation and its decline with age.

  16. The impact of federal policy on teachers' use of science manipulatives: A survey of teacher philosophy and practices

    Science.gov (United States)

    Helgoe, Catherine A.

    Recently, educators in public K-12 schools have added testing of science knowledge to the measures of Adequate Yearly Progress required by the federal No Child Left Behind (NCLB) legislation. Research of the impact of NCLB policy on general teaching practices had credited the policy with improving instruction; however, negative impacts noted included the concern that teachers "teach to the test," narrowing the curriculum. Testing as an assessment strategy was not advocated by the professional educators and scientists responsible for the National Science Education Standards (NSES). Results from previous studies pointed to a potential conflict between the NCLB reforms and the National Science Education Standards science standards, in which teachers might reduce or eliminate hands-on activities and other constructivist practices in order to focus class time on other topics and tasks. Most research on NCLB policy, however, had not evaluated instructional practices regarding science education. This study examined the relationship among teacher beliefs, specifically the strength of their constructivist versus traditional beliefs, teachers' responses to NCLB policy, and teachers' use of constructivist practices in the form of manipulatives. This study showed that national policy did have an impact on teachers; however, that impact was not specific to the hands-on practices in science education. Teachers who responded to this survey had found many benefits in student learning using manipulatives and those positive impacts on their students justified the increased use of manipulatives in the classroom. The strength of teachers' constructivist beliefs showed a weak positive correlation to choices related to curriculum priorities, learning goals and advantages in using manipulatives. However, a relationship to beliefs was not found in the changes teachers made to various instructional practices, or in how they viewed certain manipulative materials, or in how they viewed

    Phenomenon: Systems thinking is the cornerstone of systems-based practice (SBP) and a core competency in medicine and health sciences. Literature regarding how to teach or apply systems thinking in practice is limited. This study aimed to understand how educators in medicine, physical therapy, physician assistant, nursing, and speech-language pathology education programs teach and assess systems thinking and SBP. Twenty-six educators from seven different degree programs across the five professions were interviewed and program descriptions and relevant course syllabi were reviewed. Qualitative analysis was iterative and incorporated inductive and deductive methods as well as a constant comparison of units of data to identify patterns and themes. Six themes were identified: 1) participants described systems thinking as ranging across four major levels of healthcare (i.e., patient, care team, organization, and external environment); 2) participants associated systems thinking with a wide range of activities across the curriculum including quality improvement, Inter-professional education (IPE), error mitigation, and advocacy; 3) the need for healthcare professionals to understand systems thinking was primarily externally driven; 4) participants perceived that learning systems thinking occurred mainly informally and experientially rather than through formal didactic instruction; 5) participants characterized systems thinking content as interspersed across the curriculum and described a variety of strategies for teaching and assessing it; 6) participants indicated a structured framework and inter-professional approach may enhance teaching and assessment of systems thinking. Insights: Systems thinking means different things to different health professionals. Teaching and assessing systems thinking across the health professions will require further training and practice. Tools, techniques, taxonomies and expertise outside of healthcare may be used to enhance the teaching

    This study explores if and how teachers combine practices of science and of preschool (children 1-5 years old) into preschool science practice. Views of knowing may differ between science practices, traditionally associated with masculinity and rationality, and preschool practices, traditionally associated with femininity and caring. Recognising this, we have chosen to focus on how teachers' talk constructs and relates to possible ways of gaining knowledge and reaching explanations of phenomena in preschool science. The analysis builds on two concept pairs often associated with gender as well as knowing: objective-subjective and logical-intuitive. The analysed material consists of 11 group interviews where preschool teachers talk about activities concerning science content. Our results show that several ways of knowing are possible in work with science content in preschool. These include ways of knowing more associated with subjectivity, such as `individual liking' and `whole-body perception', as well as more associated with objectivity, such as `noticing differences and similarities'. Furthermore, the results show that the teachers' talk moves readily between possibilities associated with femininity (subjective and intuitive) and masculinity (objective and logical). This indicates that the teachers in this study have found ways to handle science in preschool that goes against presumed tensions between science and preschool practices. The results contribute to more nuanced ways of describing and thinking about science in preschool and pave the way for further development of science education in early childhood education.

  1. An interactional ethnographic study of the construction of literate practices of science and writing in a university science classroom

    Sena, Nuno Afonso De Freitas Lopes De

    An interactional ethnographic study informed by a sociocultural perspective was conducted to examine how a professor and students discursively and interactionally shaped the basis for engaging in the work of a community of geologists. Specifically, the study examined the role the Question of the Day, an interactive writing activity in the lecture, in affording students opportunities for learning the literate practices of science and how to incorporate them in thinking critically. A writing-intensive, introductory oceanography course given in the Geological Sciences Department was chosen because the professor designed it to emphasize writing in the discipline and science literacy within a science inquiry framework. The study was conducted in two phases: a pilot in 2002 and the current study in the Spring Quarter of 2003. Grounded in the view that members in a classroom construct a culture, this study explored the daily construction of the literate practices of science and writing. This view of classrooms was informed by four bodies of research: interactional ethnography, sociolinguistics sociology of science and Writing In the Disciplines. Through participant observation, data were collected in the lecture and laboratory settings in the form of field notes, video, interviews, and artifacts to explore issues of science literacy in discourse, social action, and writing. Examination of participation in the Question of the Day interactive writing activity revealed that it played a key role in initiating and supporting a view of science and inquiry. As the activity permitted collaboration, it encouraged students to engage in the social process to critically explore a discourse of science and key practices with and through their writing. In daily interaction, participants were shown to take up social positions as scientist and engage in science inquiry to explore theory, examine data, and articulately reformulate knowledge in making oral and written scientific arguments

    Aljabber, Jabber M.

    The purpose of this study was to investigate the attitudes of Saudi Arabian secondary preservice science teachers (SPSTs) toward a variety of science teaching practices. An ultimate, essential goal of this study was to use generated information and findings to improve the current secondary science education programs in Saudi Arabia and to develop better science teacher practices. The selected practices were posted by the National Research Council in 1999. These indicated that students learn science best through understanding of science rather than memorization of scientific facts and concepts, building new knowledge and understanding on what is already known and believed, formulating new knowledge by modifying and refining current concepts and by adding new concepts to what is already known, taking care of their own learning, social learning environments and interactions, and application of knowledge to novel situations. The study's sample consisted of all (147) SPSTs enrolled in the spring semester of 2003 in four Teachers' Colleges: Riyadh, Makkah, Taif, and Dammam. All participants were performing student teaching in secondary schools. This study used quantitative and qualitative data collection methods. Only three SPSTs were purposefully selected from each college for seven semi-structured interview questions, lasting an hour per interview. They were asked to complete a 58-item questionnaire survey and respond to four open-ended survey questions. To assess their attitudes toward the above science teaching practices, data was analyzed using the Rasch analysis model, other parametric tests (e.g., a one-way analysis of variance (ANOVA) and independent-samples t-test), and non-parametric tests (e.g., a chi-square of independent test). Furthermore, qualitative procedures were also used to assess SPSTs' views of some specific aspects about science teaching and the current secondary science education programs in Saudi Arabia. This was achieved through a careful

    In preparing a science lesson plan, teachers may deal with numerous difficulties. Having a deep understanding of their problems and their demands is extremely essential for the teachers in preparing themselves for the job. Moreover, it is also crucial for the stakeholders in planning suitable and in-need teachers' professional development programs, in school management, and in teaching aid. This study aimed to investigate the primary school science teachers' opinion toward practice of teaching and learning activities in science learning area. Target group was 292 primary science teachers who teach Grade 4 - 6 students in Khon Kaen Province, Thailand in the academic year of 2014. Data were collected using Questionnaire about Investigation the opinions of the primary science teachers toward practice of teaching and learning activities in science learning area. The questionnaires were consisted of closed questions scored on Likert scale and open-ended questions that invite a sentence response to cover from LS Process Ideas. Research findings were as follow. The primary science teachers' level of opinion toward teaching and learning science subject ranged from 3.19 - 3.93 (mean = 3.43) as "Moderate" level of practice. The primary school science teachers' needs to participate in a training workshop based on LS ranged from 3.66 - 4.22 (mean = 3.90) as "High" level. The result indicated that they were interested in attending a training course under the guidance of the Lesson Study by training on planning of management of science learning to solve teaching problems in science contents with the highest mean score 4.22. Open-ended questions questionnaire showed the needs of the implementation of the lesson plans to be actual classrooms, and supporting for learning Medias, innovations, and equipment for science experimentation.

    Supovitz, Jonathan A.; Turner, Herbert M.

    2000-11-01

    The current science education reform movement emphasizes the importance of professional development as a means of improving student science achievement. Reformers have developed a vision for professional development based upon intensive and sustained training around concrete tasks that is focused on subject-matter knowledge, connected to specific standards for student performance, and embedded in a systemic context. Using data from a National Science Foundation Teacher Enhancement program called the Local Systemic Change initiative, this study employs hierarchical linear modeling to examine the relationship between professional development and the reformers' vision of teaching practice. The findings indicate that the quantity of professional development in which teachers participate is strongly linked with both inquiry-based teaching practice and investigative classroom culture. At the individual level, teachers' content preparation also has a powerful influence on teaching practice and classroom culture. At the school level, school socioeconomic status was found to influence practice more substantially than either principal supportiveness or available resources.

    Wheeler, Nicola; Watts, Nick

    2018-03-01

    Climate change poses a significant threat to human health. Understanding how climate science can be translated into public health practice is an essential first step in enabling robust adaptation and improving resiliency to climate change. Recent research highlights the importance of iterative approaches to public health adaptation to climate change, enabling uncertainties of health impacts and barriers to adaptation to be accounted for. There are still significant barriers to adaptation, which are context-specific and thus present unique challenges to public health practice. The implementation of flexible adaptation approaches, using frameworks targeted for public health, is key to ensuring robust adaptation to climate change in public health practice. The BRACE framework provides an excellent approach for health adaptation to climate change. Combining this with the insights provided and by the adaptation pathways approach allows for more deliberate accounting of long-term uncertainties. The mainstreaming of climate change adaptation into public health practice and planning is important in facilitating this approach and overcoming the significant barriers to effective adaptation. Yet, the immediate and future limits to adaptation provide clear justification for urgent and accelerated efforts to mitigate climate change.

    Benchmarking has been adopted by educational institutions as a potentially sensitive tool for improving learning and teaching. To date there has been limited application of benchmarking methodology in the Discipline of Nutritional Science. The aim of this survey was to define core elements and outstanding practice in Nutritional Science through collaborative benchmarking. Questionnaires that aimed to establish proposed core elements for Nutritional Science, and inquired about definitions of " good" and " outstanding" practice were posted to named representatives at eight Australian universities. Seven respondents identified core elements that included knowledge of nutrient metabolism and requirement, food production and processing, modern biomedical techniques that could be applied to understanding nutrition, and social and environmental issues as related to Nutritional Science. Four of the eight institutions who agreed to participate in the present survey identified the integration of teaching with research as an indicator of outstanding practice. Nutritional Science is a rapidly evolving discipline. Further and more comprehensive surveys are required to consolidate and update the definition of the discipline, and to identify the optimal way of teaching it. Global ideas and specific regional requirements also need to be considered.

  13. Bonding Ideas About Inquiry: Exploring Knowledge and Practices of Metacognition in Beginning Secondary Science Teachers

    Science.gov (United States)

    Rivero Arias, Ana Margarita

    Metacognition, identified generally as "thinking about thinking", plays a fundamental role in science education. It enhances the understanding of science as a way to generate new knowledge using scientific concepts and practices. Moreover, metacognition supports the development of students' life-long problem solving, collaboration, and critical thinking skills. When teachers use metacognition with intention, it can promote students' agency and responsibility for their own learning. However, despite all of its benefits, metacognition is rarely seen in secondary science classrooms. Thus, it is important to understand what beginning teachers know and how they use metacognition during their first years in order to find ways to prepare and support them in incorporating metacognitive practices into their science teaching. The purpose of this multimethod study was to describe the metacognitive knowledge and experiences of beginning science teachers. For the quantitative research strand, I surveyed 36 secondary science teachers about their awareness of metacognition and used classroom observations coded from a larger research study to identify how often teachers were using metacognition to teach science. For the qualitative strand, I interviewed 15 participants about their knowledge and experiences of metacognition (including reflective practices) and spent two weeks observing two of the teachers who described exemplary metacognitive teaching practices. I found that participants had a solid awareness of metacognition, but considered the term complicated to enact, difficult for students, and less important to focus on during their first years of teaching than other elements such as content. Additionally, teaching experience seemed to have an effect on teachers' knowledge and experiences of metacognition. However, participants who were using metacognitive practices had recognized their importance since the beginning of their teaching. Reflective practices can help improve

    Across the United States institutions of higher education address educational reform by valuing scholarship that focuses on teaching and learning, especially in STEM fields. University science departments can encourage teaching scholarship by hiring science faculty with education specialties (SFES), individuals who have expertise in both science and science education. The goal of this study was to understand how the epistemological beliefs and teaching practices of SFES relate to national reform efforts in science teaching promoting student-centered instruction. The research questions guiding this investigation were: (1) What epistemological belief systems do science faculty with education specialties espouse concerning the teaching and learning of science?; and (2) What are the classroom practices of science faculty with education specialties? How are these practices congruent with the reform efforts described by the National Research Council (1996, 2001, 2003)? The theoretical framework guiding the study was interdisciplinarity, the integration of knowledge between two or more disciplines (science and science pedagogy). The research design employed mixed (qualitative and quantitative) approaches and focused on 25 volunteer SFES participants. The TBI, ATI, and RTOP were used to triangulate self-report and videotaped teaching vignettes, and develop profiles of SFES. Of the 25 SFES participants, 82 percent of their beliefs were transitional or student-centered beliefs. Seventy-two percent of the 25 SFES espoused more student-focused than teacher focused approaches. The classroom practices of 10 SFES were on average transitional in nature (at the boundary of student-focused and teacher-focused). The beliefs of SFES appeared to be influenced by the sizes of their courses, and were positive correlated with reform-based teaching practices. There was a relationship between the degree to which they implemented reform-based practice and their perceived level of

  16. Career education attitudes and practices of K-12 science educators

    Science.gov (United States)

    Smith, Walter S.

    A random sample of 400 K-12 science educators who were members of the National Science Teachers Association were surveyed regarding their attitude toward and practice of career education in their science teaching. These science teachers rejected a narrowly vocational view, favoring instead a conception of career education which included self-perception, values analysis, and vocational skills objectives. The science educators affirmed the importance of career education for a student's education, asserted career education ought to be taught in their existing science courses, and expressed a willingness to do so. Fewer than one-third of the science teachers, however, reported incorporating career education at least on a weekly basis in their science lessons. The major impediment to including more career education in science teaching was seen to be their lack of knowledge of methods and materials relevant to science career education, rather than objections from students, parents, or administrators; their unwillingness; or their evaluation of career education as unimportant. Thus, in order to improve this aspect of science teaching, science teachers need more concrete information about science career education applications.

    A study on implementing authentic assessment program through workshop was conducted to investigate the improvement of the competence of science teachers in designing performance assessment in real life situation at school level context. A number of junior high school science teachers and students as participants were involved in this study. Data was collected through questionnaire, observation sheets, and pre-and post-test during 4 day workshop. This workshop had facilitated them direct experience with seventh grade junior high school students during try out. Science teachers worked in group of four and communicated each other by think-pair share in cooperative learning approach. Research findings show that generally the science teachers’ involvement and their competence in authentic assessment improved. Their knowledge about the nature of assessment in relation to the nature of science and its instruction was improved, but still have problem in integrating their design performance assessment to be implemented in their lesson plan. The 7th grade students enjoyed participating in the science activities, and performed well the scientific processes planned by group of science teachers. The response of science teachers towards the workshop was positive. They could design the task and rubrics for science activities, and revised them after the implementation towards the students. By participating in this workshop they have direct experience in designing and trying out their ability within their professional community in real situation towards their real students in junior high school.

    This study evaluated weather educational outcomes of nurse education meet the requirements of nursing practice by exploring the correspondence between nurse educators' and nurse managers' assessments of novice nurses' professional competence. The purpose was to find competence areas contributing to the acknowledged practice-theory gap. A cross-sectional, comparative design using the Nurse Competence Scale was applied. The sample comprised nurse educators (n = 86) and nurse managers (n = 141). Descriptive and inferential statistics were used in the data analysis. Educators assessed novice nurses' competence to a significantly higher level than managers in all competence areas (p competencies related to immediate patient care, commitment to ethical values, maintaining professional skills and nurses' care of the self. The biggest differences were in competencies related to developmental and evaluation tasks, coaching activities, use of evidence-based knowledge and in activities which required mastering a comprehensive view of care situations. However, differences between educators' and managers' assessments were strongly associated with their age and work experience. Active and improved collaboration should be focused on areas in which the differences between educators' and managers' assessments greatly differ in ensuring novice nurses' fitness for practice. © 2014 The Authors.

    New approaches for teaching and assessing scientific inquiry and practices are essential for guiding students to make the informed decisions required of an increasingly complex and global society. The Science Skills approach described here guides students to develop an understanding of the experimental skills required to perform a scientific investigation. An individual teacher's investigation of the strategies and tools she designed to promote scientific inquiry in her classroom is outlined. This teacher-driven action research in the high school biology classroom presents a simple study design that allowed for reciprocal testing of two simultaneous treatments, one that aimed to guide students to use vocabulary to identify and describe different scientific practices they were using in their investigations—for example, hypothesizing, data analysis, or use of controls—and another that focused on scientific collaboration. A knowledge integration (KI) rubric was designed to measure how students integrated their ideas about the skills and practices necessary for scientific inquiry. KI scores revealed that student understanding of scientific inquiry increased significantly after receiving instruction and using assessment tools aimed at promoting development of specific inquiry skills. General strategies for doing classroom-based action research in a straightforward and practical way are discussed, as are implications for teaching and evaluating introductory life sciences courses at the undergraduate level.

    In this article we examine how bilingual students construe relations between everyday language and the language of science. Studies concerning bilingual students language use in science class have mainly been conducted in settings where both the teacher and the students speak the same minority language. In this study data was collected in a class consisting of students aged 13-14. All students had Turkish as their minority language, whereas the teacher's minority language was Bosnian. The class was observed when they were working with acids and bases. In addition, the students were interviewed in groups. They were asked about how they use their languages during science lessons and then asked to describe and explain scientific phenomena and processes that had been a part of the observed lessons. For the analysis, practical epistemology analysis and the theory of translanguaging were used. The results show how the students' everyday language repertoire may limit their possibilities to make meaning of science. In particular, the teacher's practice of facilitating and supporting students' understanding of science content by relating it to concrete examples took another direction since the everyday words he used were not a part of the students' language repertoire. The study also shows how the students used their minority language as a resource to translate words from Swedish to Turkish in order to proceed with the science activities. However, translating scientific concepts was problematic and led to the students' descriptions of the concepts not being in line with how they are viewed in science. Finally, the study also demonstrates how monolingual exams may limit bilingual students' achievements in science. The study contributes by presenting and discussing circumstances that need to be taken into consideration when planning and conducting science lessons in classes where the teacher and the student do not share the same minority language.

    A 2014 survey conducted by the Pew Research Center asked members of the American Association for the Advancement of Science about their support for active engagement in public policy debates. The survey found that 87% of the respondents supported scientists taking an active role in public policy debates about science and technology (S&T), but most believed that regulations related to areas like land use and clean air and water are not guided by the best science. Despite the demand for actionable scientific information by policy makers, these survey results underscore the gap that exists between the scientific and the public policy communities. There are fundamental differences that exist between the perspectives of these two groups, even within Federal S&T agencies that are required to balance the perspectives of the science and policy communities in order to fulfill their agency mission. In support of an ongoing agency effort to strengthen communication and interaction among staff, we led a Federal S&T agency office through an examination and comparison of goals, processes, external drivers, decision making, and timelines within their organization. This workshop activity provided an opportunity to identify the interdependence of science and policy, as well as the challenges to developing effective science-based policy solutions. The workshop featured strategies for achieving balanced science policy outcomes using examples from a range of Federal S&T agencies. The examples presented during the workshop illustrated best practices for more effective communication and interaction to resolve complex science policy issues. The workshop culminated with a group activity designed to give participants the opportunity to identify the challenges and apply best practices to real world science policy problems. Workshop examples and outcomes will be presented along with lessons learned from this agency engagement activity.

  10. Best practices for measuring students' attitudes toward learning science.

    2013-01-01

    Science educators often characterize the degree to which tests measure different facets of college students' learning, such as knowing, applying, and problem solving. A casual survey of scholarship of teaching and learning research studies reveals that many educators also measure how students' attitudes influence their learning. Students' science attitudes refer to their positive or negative feelings and predispositions to learn science. Science educators use attitude measures, in conjunction with learning measures, to inform the conclusions they draw about the efficacy of their instructional interventions. The measurement of students' attitudes poses similar but distinct challenges as compared with measurement of learning, such as determining validity and reliability of instruments and selecting appropriate methods for conducting statistical analyses. In this review, we will describe techniques commonly used to quantify students' attitudes toward science. We will also discuss best practices for the analysis and interpretation of attitude data.

  11. Citizen Science and Biomedical Research: Implications for Bioethics Theory and Practice

    Directory of Open Access Journals (Sweden)

    Chris W Callaghan

    2016-10-01

    Full Text Available Certain trends in scientific research have important relevance to bioethics theory and practice. A growing stream of literature relates to increasing transparency and inclusivity of populations (stakeholders in scientific research, from high volume data collection, synthesis, and analysis to verification and ethical scrutiny. The emergence of this stream of literature has implications for bioethics theory and practice. This paper seeks to make explicit these streams of literature and to relate these to bioethical issues, through consideration of certain extreme examples of scientific research where bioethical engagement is vital. Implications for theory and practice are derived, offering useful insights derived from multidisciplinary theory. Arguably, rapidly developing fields of citizen science such as informing science and others seeking to maximise stakeholder involvement in both research and bioethical engagement have emerged as a response to these types of issues; radically enhanced stakeholder engagement in science may herald a new maximally inclusive and transparent paradigm in bioethics based on lessons gained from exposure to increasingly uncertain ethical contexts of biomedical research.

    2016-09-01

    Full Text Available Background: Librarians often teach evidence-based practice (EBP within health sciences curricula. It is not known what teaching methods are most effective. Methods: A systematic review of the literature was conducted searching CINAHL, EMBASE, ERIC, LISTA, PubMed, Scopus, and others. Searches were completed through December 2014. No limits were applied. Hand searching of Medical Library Association annual meeting abstracts from 2009–2014 was also completed. Studies must be about EBP instruction by a librarian within undergraduate or graduate health sciences curricula and include skills assessment. Studies with no assessment, letters and comments, and veterinary education studies were excluded. Data extraction and critical appraisal were performed to determine the risk of bias of each study. Results: Twenty-seven studies were included for analysis. Studies occurred in the United States (20, Canada (3, the United Kingdom (1, and Italy (1, with 22 in medicine and 5 in allied health. Teaching methods included lecture (20, small group or one-on-one instruction (16, computer lab practice (15, and online learning (6. Assessments were quizzes or tests, pretests and posttests, peer review, search strategy evaluations, clinical scenario assignments, or a hybrid. Due to large variability across studies, meta-analysis was not conducted. Discussion: Findings were weakly significant for positive change in search performance for most studies. Only one study compared teaching methods, and no one teaching method proved more effective. Future studies could conduct multisite interventions using randomized or quasi-randomized controlled trial study design and standardized assessment tools to measure outcomes.

  17. The Black Cultural Ethos and science teachers' practices: A case study exploring how four high school science teachers meet their African American students' needs in science

    Science.gov (United States)

    Strachan, Samantha L.

    The underachievement of African American students in science has been a persistent problem in science education. The achievement patterns of African American students indicate that researchers must take a closer look at the types of practices that are being used to meet these students' needs in science classrooms. Determining why science teachers decide to employ certain practices in their classrooms begins with a careful examination of teachers' beliefs as well as their instructional approaches. The purpose of this study was to explore four urban high school science teachers' beliefs about their African American students' learning needs and to investigate how these teachers go about addressing students' needs in science classrooms. This research study also explored the extent to which teachers' practices aligned with the nine dimensions of an established cultural instructional theory, namely the Black Cultural Ethos. Qualitative research methods were employed to gather data from the four teachers. Artifact data were collected from the teachers and they were interviewed and observed. Believing that their students had academic-related needs as well as needs tied to their learning preferences, the four science teachers employed a variety of instructional strategies to meet their students where they were in learning. Overall, the instructional strategies that the teachers employed to meet their students' needs aligned with five of the nine tenets of the Black Cultural Ethos theory.

    We examine issues to consider when reframing conservation science and practice in the context of global change. New framings of the links between ecosystems and society are emerging that are changing peoples' values and expectations of nature, resulting in plural perspectives on conservation. Reframing conservation for global change can thus be regarded as a stage in the evolving relationship between people and nature rather than some recent trend. New models of how conservation links with transformative adaptation include how decision contexts for conservation can be reframed and integrated with an adaptation pathways approach to create new options for global-change-ready conservation. New relationships for conservation science and governance include coproduction of knowledge that supports social learning. New processes for implementing adaptation for conservation outcomes include deliberate practices used to develop new strategies, shift world views, work with conflict, address power and intergenerational equity in decisions, and build consciousness and creativity that empower agents to act. We argue that reframing conservation for global change requires scientists and practitioners to implement approaches unconstrained by discipline and sectoral boundaries, geopolitical polarities, or technical problematization. We consider a stronger focus on inclusive creation of knowledge and the interaction of this knowledge with societal values and rules is likely to result in conservation science and practice that meets the challenges of a postnormal world. © 2017 The Authors.

  1. Inspiring Instructional Change in Elementary School Science: The Relationship Between Enhanced Self-efficacy and Teacher Practices

    Science.gov (United States)

    Sandholtz, Judith Haymore; Ringstaff, Cathy

    2014-10-01

    This longitudinal study examined the extent to which teachers' participation in a 3-year professional development program enhanced their self-efficacy and prompted changes in science instruction in the early elementary grades. The study used a mixed-methods design, and included 39 teachers who taught in kindergarten, first grade, or second grade classrooms in rural school districts. Data sources, administered pre-program and at the end of each year, included a self-efficacy assessment and teacher survey. Interviews and classroom observations provided corroborating data about teachers' beliefs and science instruction. Results showed significant increases in teachers' overall self-efficacy in teaching science, personal efficacy, and outcome expectancy efficacy during the 3 years. Gains in self-efficacy were correlated with changes in reported instructional practices, particularly student participation activities. However, changes in self-efficacy tended not to be correlated with changes in instructional time. Contextual factors beyond teachers' direct control, such as curricular and testing requirements in mathematics and language arts influenced time allotted to science instruction.

  4. Real life narratives enhance learning about the 'art and science' of midwifery practice.

    Science.gov (United States)

    Gilkison, Andrea; Giddings, Lynne; Smythe, Liz

    2016-03-01

    Health professional educators have long grappled with how to teach the more elusive art of practice alongside the science (a term that encompasses the sort of professional knowledge that can be directly passed on). A competent practitioner is one who knows when, how and for whom to apply knowledge and skills, thereby making the links between theory and practice. They combine art and science in such a way that integrates knowledge with insight. This participatory hermeneutic study explored the experience of teachers and students of implementing a narrative-centred curriculum in undergraduate midwifery education. It revealed that when real life narratives were central to the learning environment, students' learning about the art of midwifery practice was enhanced as they learned about midwifery decisions, reflected on their own values and beliefs and felt an emotional connection with the narrator. Further, art and science became melded together in the context specific wisdom of practice (phronesis).

  5. Relationships Between the Way Students Are Assessed in Science Classrooms and Science Achievement Across Canada

    2018-04-01

    Canadian students experience many different assessments throughout their schooling (O'Connor 2011). There are many benefits to using a variety of assessment types, item formats, and science-based performance tasks in the classroom to measure the many dimensions of science education. Although using a variety of assessments is beneficial, it is unclear exactly what types, format, and tasks are used in Canadian science classrooms. Additionally, since assessments are often administered to help improve student learning, this study identified assessments that may improve student learning as measured using achievement scores on a standardized test. Secondary analyses of the students' and teachers' responses to the questionnaire items asked in the Pan-Canadian Assessment Program were performed. The results of the hierarchical linear modeling analyses indicated that both students and teachers identified teacher-developed classroom tests or quizzes as the most common types of assessments used. Although this ranking was similar across the country, statistically significant differences in terms of the assessments that are used in science classrooms among the provinces were also identified. The investigation of which assessment best predicted student achievement scores indicated that minds-on science performance-based tasks significantly explained 4.21% of the variance in student scores. However, mixed results were observed between the student and teacher responses towards tasks that required students to choose their own investigation and design their own experience or investigation. Additionally, teachers that indicated that they conducted more demonstrations of an experiment or investigation resulted in students with lower scores.

  6. Unpacking Docent Practice in Free Choice Science Learning Settings: A Qualitative Study Documenting the What and Whys of Docent Interpretive Practice

    Science.gov (United States)

    Good, Laura H.

    Museum settings including aquariums, zoos and science centers rely heavily on their volunteer docent populations to interact with and communicate science and conservation concepts to the visiting public. The interactions docents have with museum visitors are important to meeting the educational expectations of museums and improving public science literacy as a whole, yet research to date is limited around docent practice, docents' reflections on that practice nor the sources for docents to learn that practice. Thus, we have little understanding of the interpretive practice docents actually undertake whilst interacting with visitors, why they choose to enact particular strategies, and how they came to learn those practices. Using a grounded qualitative approach within a framework of mediated action and cultural historical activity theory, this case study utilized video observations of docent practice at a science center, pre and post observation interviews, and focus groups to 1) document docent practices for engaging visitors, 2) explain those practices from the docents' own perspectives, and 3) examine those practices from the point of view of how they align with teaching and learning theories and interpretive practice. Thematic analysis using constant comparative methods demonstrate four claims about docent practice: 1) docents view teaching in the museum as opportunities to spark interest with these new experiences. Practices are chosen to engage visitors in these experiences. Docents choose to highlight these experiences as they believe they are reasons to be engaged; 2) docents as teachers are perceptive about their audience. They pay attention to patterns and provide information in response to those patterns. Docents utilize a shared repertoire of practice and information in their community developed from understanding visitor patterns of interest; 3) docents care about their setting and the exhibits within it. They also care about the visitor experience as a

  8. Quality in environmental science for policy: Assessing uncertainty as a component of policy analysis

    International Nuclear Information System (INIS)

    Maxim, Laura; Sluijs, Jeroen P. van der

    2011-01-01

    The sheer number of attempts to define and classify uncertainty reveals an awareness of its importance in environmental science for policy, though the nature of uncertainty is often misunderstood. The interdisciplinary field of uncertainty analysis is unstable; there are currently several incomplete notions of uncertainty leading to different and incompatible uncertainty classifications. One of the most salient shortcomings of present-day practice is that most of these classifications focus on quantifying uncertainty while ignoring the qualitative aspects that tend to be decisive in the interface between science and policy. Consequently, the current practices of uncertainty analysis contribute to increasing the perceived precision of scientific knowledge, but do not adequately address its lack of socio-political relevance. The 'positivistic' uncertainty analysis models (like those that dominate the fields of climate change modelling and nuclear or chemical risk assessment) have little social relevance, as they do not influence negotiations between stakeholders. From the perspective of the science-policy interface, the current practices of uncertainty analysis are incomplete and incorrectly focused. We argue that although scientific knowledge produced and used in a context of political decision-making embodies traditional scientific characteristics, it also holds additional properties linked to its influence on social, political, and economic relations. Therefore, the significance of uncertainty cannot be assessed based on quality criteria that refer to the scientific content only; uncertainty must also include quality criteria specific to the properties and roles of this scientific knowledge within political, social, and economic contexts and processes. We propose a conceptual framework designed to account for such substantive, contextual, and procedural criteria of knowledge quality. At the same time, the proposed framework includes and synthesizes the various

    A critical aspect of teacher education is gaining pedagogical content knowledge of how to teach science for conceptual understanding. Given the time limitations of college methods courses, it is difficult to touch on more than a fraction of the science topics potentially taught across grades K-8, particularly in the context of relevant pedagogies. This research and development work centers on constructing a formative assessment resource to help expose pre-service teachers to a greater number of science topics within teaching episodes using various modes of instruction. To this end, 100 problem-based, science pedagogy assessment items were developed via expert group discussions and pilot testing. Each item contains a classroom vignette followed by response choices carefully crafted to include four basic pedagogies (didactic direct, active direct, guided inquiry, and open inquiry). The brief but numerous items allow a substantial increase in the number of science topics that pre-service students may consider. The intention is that students and teachers will be able to share and discuss particular responses to individual items, or else record their responses to collections of items and thereby create a snapshot profile of their teaching orientations. Subsets of items were piloted with students in pre-service science methods courses, and the quantitative results of student responses were spread sufficiently to suggest that the items can be effective for their intended purpose.

  10. Practical relevance of pattern uniqueness in forensic science.

    Jayaprakash, Paul T

    2013-09-10

    Uniqueness being unprovable, it has recently been argued that individualization in forensic science is irrelevant and, probability, as applied for DNA profiles, should be applied for all identifications. Critiques against uniqueness have omitted physical matching, a realistic and tangible individualization that supports uniqueness. Describing case examples illustrating pattern matches including physical matching, it is indicated that individualizations are practically relevant for forensic science as they establish facts on a definitive basis providing firm leads benefitting criminal investigation. As a tenet of forensic identification, uniqueness forms a fundamental paradigm relevant for individualization. Evidence on the indeterministic and stochastic causal pathways of characteristics in patterns available in the related fields of science sufficiently supports the proposition of uniqueness. Characteristics involved in physical matching and matching achieved in patterned evidence existing in the state of nature are not events amenable for counting; instead these are ensemble of visible units occupying the entire pattern area stretching the probability of re-occurrence of a verisimilitude pattern into infinity offering epistemic support to uniqueness. Observational methods are as respectable as instrumental or statistical methods since they are capable of generating results that are tangible and obviously valid as in physical matching. Applying the probabilistic interpretation used for DNA profiles to the other patterns would be unbefitting since these two are disparate, the causal pathways of the events, the loci, in the manipulated DNA profiles being determinable. While uniqueness enables individualizations, it does not vouch for eliminating errors. Instead of dismissing uniqueness and individualization, accepting errors as human or system failures and seeking remedial measures would benefit forensic science practice and criminal investigation.

  11. Estimating the effects of wetland conservation practices in croplands: Approaches for modeling in CEAP–Cropland Assessment

    Science.gov (United States)

    De Steven, Diane; Mushet, David

    2018-01-01

    Quantifying the current and potential benefits of conservation practices can be a valuable tool for encouraging greater practice adoption on agricultural lands. A goal of the CEAP-Cropland Assessment is to estimate the environmental effects of conservation practices that reduce losses (exports) of soil, nutrients, and pesticides from farmlands to streams and rivers. The assessment approach combines empirical data on reported cropland practices with simulation modeling that compares field-level exports for scenarios “with practices” and “without practices.” Conserved, restored, and created wetlands collectively represent conservation practices that can influence sediment and nutrient exports from croplands. However, modeling the role of wetlands within croplands presents some challenges, including the potential for negative impacts of sediment and nutrient inputs on wetland functions. This Science Note outlines some preliminary solutions for incorporating wetlands and wetland practices into the CEAP-Cropland modeling framework. First, modeling the effects of wetland practices requires identifying wetland hydrogeomorphic type and accounting for the condition of both the wetland and an adjacent upland zone. Second, modeling is facilitated by classifying wetland-related practices into two functional categories (wetland and upland buffer). Third, simulating practice effects requires alternative field configurations to account for hydrological differences among wetland types. These ideas are illustrated for two contrasting wetland types (riparian and depressional).

    What would data science look like if its key critics were engaged to help improve it, and how might critiques of data science improve with an approach that considers the day-to-day practices of data science? This article argues for scholars to bridge the conversations that seek to critique data science and those that seek to advance data science practice to identify and create the social and organizational arrangements necessary for a more ethical data science. We summarize four critiques that are commonly made in critical data studies: data are inherently interpretive, data are inextricable from context, data are mediated through the sociomaterial arrangements that produce them, and data serve as a medium for the negotiation and communication of values. We present qualitative research with academic data scientists, "data for good" projects, and specialized cross-disciplinary engineering teams to show evidence of these critiques in the day-to-day experience of data scientists as they acknowledge and grapple with the complexities of their work. Using ethnographic vignettes from two large multiresearcher field sites, we develop a set of concepts for analyzing and advancing the practice of data science and improving critical data studies, including (1) communication is central to the data science endeavor; (2) making sense of data is a collective process; (3) data are starting, not end points, and (4) data are sets of stories. We conclude with two calls to action for researchers and practitioners in data science and critical data studies alike. First, creating opportunities for bringing social scientific and humanistic expertise into data science practice simultaneously will advance both data science and critical data studies. Second, practitioners should leverage the insights from critical data studies to build new kinds of organizational arrangements, which we argue will help advance a more ethical data science. Engaging the insights of critical data studies will

    2008-04-01

    Health care organisations such as the World Health Organisation (WHO) and An Bord Altranais (ABA, The Irish Nursing Registration Board) demand higher standards of new graduate nurses than heretofore. This is in conjunction with the implementation of degree programmes for undergraduate nurse education. These organisations stipulate that graduates must be well-educated, accountable, and can demonstrate the skills of a safe, caring and competent decision-making practitioner. The Bachelor of Science (BSc) four-year degree programme for undergraduate nurse education was introduced in Ireland in 2002, and is provided in universities and colleges of higher education throughout The Republic of Ireland. During the implementation process, each university and college of higher education developed a range of assessment strategies to clinically assess students. Preceptor nurses were subsequently assigned the responsibility of clinically assessing students, a remit previously undertaken by Clinical Ward/Unit Nurse Managers. Preceptors are qualified nurses, working in clinical units who are specially prepared to support BSc students during clinical placements. The purpose of this study was to explore to what extent preceptor nurses use the devised assessment strategies to clinically assess BSc students in one university in The Republic of Ireland. Data were collected by using a questionnaire distributed to all known preceptors in General, Psychiatric and Intellectual Disability nursing, during year four of the first cycle of the BSc programme. Findings from this descriptive study revealed that many preceptors were inexperienced, did not fully comprehend the assessment process and were not applying all of the recommended assessment strategies when assessing students in clinical practice. In light of these findings suggestions are made in the context of further research, management and education.

  15. The Figured Worlds of High School Science Teachers: Uncovering Three-Dimensional Assessment Decisions

    Science.gov (United States)

    Ewald, Megan

    As a result of recent mandates of the Next Generation Science Standards, assessments are a "system of meaning" amidst a paradigm shift toward three-dimensional assessments. This study is motivated by two research questions: 1) how do high school science teachers describe their processes of decision-making in the development and use of three-dimensional assessments and 2) how do high school science teachers negotiate their identities as assessors in designing three-dimensional assessments. An important factor in teachers' assessment decision making is how they identify themselves as assessors. Therefore, this study investigated the teachers' roles as assessors through the Sociocultural Identity Theory. The most important contribution from this study is the emergent teacher assessment sub-identities: the modifier-recycler , the feeler-finder, and the creator. Using a qualitative phenomenological research design, focus groups, three-series interviews, think-alouds, and document analysis were utilized in this study. These qualitative methods were chosen to elicit rich conversations among teachers, make meaning of the teachers' experiences through in-depth interviews, amplify the thought processes of individual teachers while making assessment decisions, and analyze assessment documents in relation to teachers' perspectives. The findings from this study suggest that--of the 19 participants--only two teachers could consistently be identified as creators and aligned their assessment practices with NGSS. However, assessment sub-identities are not static and teachers may negotiate their identities from one moment to the next within socially constructed realms of interpretation known as figured worlds. Because teachers are positioned in less powerful figured worlds within the dominant discourse of standardization, this study raises awareness as to how the external pressures from more powerful figured worlds socially construct teachers' identities as assessors.

  19. The ABCs of an evolutionary education science: The academic, behavioral, and cultural implications of an evolutionary approach to education theory and practice

    Science.gov (United States)

    Kauffman, Rick, Jr.

    Calls for improving research-informed policy in education are everywhere. Yet, while there is an increasing trend towards science-based practice, there remains little agreement over which of the sciences to consult and how to organize a collective effort between them. What Education lacks is a general theoretical framework through which policies can be constructed, implemented, and assessed. This dissertation submits that evolutionary theory can provide a suitable framework for coordinating educational policies and practice, and can provide the entire field of education with a clearer sense of how to better manage the learning environment. This dissertation explores two broad paths that outline the conceptual foundations for an Evolutionary Education Science: "Teaching Evolution" and "Using Evolution to Teach." Chapter 1 introduces both of these themes. After describing why evolutionary science is best suited for organizing education research and practice, Chapter 1 proceeds to "teach" an overview of the "evolutionary toolkit"---the mechanisms and principles that underlie the modern evolutionary perspective. The chapter then employs the "toolkit" in examining education from an evolutionary perspective, outlining the evolutionary precepts that can guide theorizing and research in education, describing how educators can "use evolution to teach.". Chapters 2-4 expand on this second theme. Chapters 2 and 3 describe an education program for at-risk 9th and 10th grade students, the Regents Academy, designed entirely with evolutionary principles in mind. The program was rigorously assessed in a randomized control design and has demonstrated success at improving students' academic performance (Chapter 2) and social & behavioral development (Chapter 3). Chapter 4 examines current teaching strategies that underlie effective curriculum-instruction-assessment practices and proposes a framework for organizing successful, evidence-based strategies for neural

  20. Goethe's Conception of "Experiment as Mediator" and Implications for Practical Work in School Science

    Park, Wonyong; Song, Jinwoong

    2018-03-01

    There has been growing criticism over the aims, methods, and contents of practical work in school science, particularly concerning their tendency to oversimplify the scientific practice with focus on the hypothesis-testing function of experiments. In this article, we offer a reading of Johann Wolfgang von Goethe's scientific writings—particularly his works on color as an exquisite articulation of his ideas about experimentation—through the lens of practical school science. While avoiding the hasty conclusions made from isolated experiments and observations, Goethe sought in his experiments the interconnection among diverse natural phenomena and rejected the dualistic epistemology about the relation of humans and nature. Based on a close examination of his color theory and its underlying epistemology, we suggest three potential contributions that Goethe's conception of scientific experimentation can make to practical work in school science.

    2011-06-01

    Examination of a limited number of publisher's Instructions for Authors, guidelines from two scientific societies, and the widely accepted policy document of the International Committee of Medical Journal Editors (ICMJE) provided useful information on authorship practices. Three of five journals examined (Nature, Science, and the Proceedings of the National Academy of Sciences) publish papers across a variety of disciplines. One is broadly focused on topics in medical research (New England Journal of Medicine) and one publishes research reports in a single discipline (Journal of Bacteriology). Similar elements of publication policy and accepted practices were found across the policies of these journals articulated in their Instructions for Authors. A number of these same elements were found in the professional society guidelines of the Society for Neuroscience and the American Chemical Society, as well as the ICMJE Uniform Requirements for Manuscripts Submitted to Biomedical Journals. Taken together, these sources provide the basis for articulating best practices in authorship in scientific research. Emerging from this material is a definition of authorship, as well as policy statements on duplicative publication, conflict of interest disclosure, electronic access, data sharing, digital image integrity, and research requiring subjects' protection, including prior registration of clinical trials. These common elements provide a foundation for teaching about scientific authorship and publication practices across biomedical and life sciences disciplines.

    This study analysed 10 top-performing regions in PISA 2015 on their science performances and instructional practices. The regions include Singapore, Japan, Estonia, Taipei, Finland, Macao, Canada, Hong Kong, China and Korea. The science performances of the 10 regions and their teaching practices are described and compared. The construct of enquiry-based instruction as developed in PISA 2015 is revised into two new constructs using factor analysis. Then, the relationships of the teaching practices with science performance are analysed using hierarchical linear modelling. Adaptive instruction, teacher-directed instruction and interactive application are found positively associated with performance in all regions, while investigation and perceived feedback are all negative. The regions except Japan and Korea tend to have a high frequency of teacher-directed instruction facilitated by more or less authoritative class discussion in class. A fair amount of practical work is done, but not many of them are investigations. The cultural influences on teaching practices are discussed on how an amalgam of didactic and constructivist pedagogy is created by the Western progressive educational philosophy meeting the Confucian culture. The reasons for investigation's negative association with performance are also explored.

  6. Secondary science teachers' attitudes toward and beliefs about science reading and science textbooks

    Yore, Larry D.

    Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.

    2011-10-01

    Although there has been much international commentary, little is known about the interface between traditional knowledge and scientific research in modern naturopathic practice. This study aimed to explore this interface from the perspective of naturopaths. Semistructured interviews were conducted with naturopaths in current practice. The participants were selected using purposive sampling, and the data from the interviews were interpreted using thematic analysis. Interviews were conducted in a place suitable to each participant. Twelve (12) naturopaths in current clinical practice were interviewed. The participants represented a diversity of characteristics including gender, time in practice, level of qualification, and clinical contact hours per week. Thematic analysis was used to identify common themes from the interviews. Analysis identified a disparity in practitioner definition of what constitutes traditional information. However, it also identified that traditional knowledge is considered a valid source of information, whereas the validity and value of modern research is questioned. There is also tension between these two information sources, with science being argued to both support traditional knowledge, while also undermining its value. This tension seems to be overcome by practitioners' use of traditional knowledge to direct their own research, as well as drawing upon their knowledge of science to explain traditional knowledge as yet not researched. The findings of this qualitative study reveal tensions and ambiguities around the interface between tradition and science with regard to naturopathic clinical practice. Understanding these findings may assist individuals and groups within the naturopathic profession, as well as those outside the profession engaging and collaborating with naturopaths.

    A concept of SCIENCE ASSESSMENT (SA) is proposed to support a research program of the so-called big science. The SA System should be established before the demonstration reactor is realized, and the system is classified into four categories: (1) Resource Economy Assessment (REA) (cost evaluation and availability of rare resource materials), (2) Risk Assessment (RA) (structural safety during operation and accident), (3) Environmental Assessment (EA) (adaptability to environments), and (4) Socio-Political Assessment (SPA) (from local public acceptance to national policy acceptance). Here, REA to the published conceptual designs of commercial fusion power plants (most of them are TOKAMAK) is carried out as the first step. The energy analysis method is imployed because the final goal of fusion plant is to supply energy. The evaluation index is the energy ratio (= output/input). Computer code for energy analysis was developed, to which the material inventory table from the conceptual design and the database for the energy intensity (= energy required to obtain a unit amount of materials) were prepared.

    Malaysian Nuclear Agency (Nuclear Malaysia) is the leading agency in introducing and promoting the application of nuclear science technology in Malaysia. The agency provides major nuclear facilities purposely for research and commercialisation such as reactor, irradiation plants and radioisotope production laboratory. When dealing with ionizing radiation, there is an obligatory requirement to monitor and assess the radiation exposure to the workers. The personal dose of radiation workers were monitored monthly by assessing their Thermoluminescence Dosimeter (TLD) dose reading. This paper will discuss the current practice in managing, assessing, record keeping and reporting of the occupational exposure in Nuclear Malaysia including the Health Physic Group roles and challenges. The statistics on occupational radiation exposure of monitored workers working in different fields in Nuclear Malaysia from 2011 - 2013 will also be presented. The results show that the null hypothesis (H{sub 0}) was accepted which the means of every populations are all equal or not differ significantly. This hypothesis states that the dose exposure received by the radiation workers in Nuclear Malaysia is similar and there were no significant changes from 2011 to 2013. The radiation monitoring programme correlate with the requirement of our national law, the Atomic Energy Licensing Act 1984 (Act 304)

The agency provides major nuclear facilities purposely for research and commercialisation such as reactor, irradiation plants and radioisotope production laboratory. When dealing with ionizing radiation, there is an obligatory requirement to monitor and assess the radiation exposure to the workers. The personal dose of radiation workers were monitored monthly by assessing their Thermoluminescence Dosimeter (TLD) dose reading. This paper will discuss the current practice in managing, assessing, record keeping and reporting of the occupational exposure in Nuclear Malaysia including the Health Physic Group roles and challenges. The statistics on occupational radiation exposure of monitored workers working in different fields in Nuclear Malaysia from 2011 - 2013 will also be presented. The results show that the null hypothesis (H₀) was accepted which the means of every populations are all equal or not differ significantly. This hypothesis states that the dose exposure received by the radiation workers in Nuclear Malaysia is similar and there were no significant changes from 2011 to 2013. The radiation monitoring programme correlate with the requirement of our national law, the Atomic Energy Licensing Act 1984 (Act 304).

    Nelson, Adrienne Fleurette

    The purpose of this mixed method research study was to examine the constructivist beliefs and instructional practices of secondary science teachers. The research also explored situations that impacted whether or not student centered instruction occurred. The study revealed science teachers held constructive beliefs pertaining to student questioning of the learning process and student autonomy in interacting with other learners. Teachers held the least constructivist beliefs pertaining to student teacher collaboration on lesson design. Additionally, teacher beliefs and practice were not congruent due to instructional practices being deemed less constructivist than reported. The study found that curricular demands, teacher perceptions about students, inadequate laboratory resources, and the lack of teacher understanding about the components of constructivist instruction inhibited student centered instruction. The results of this study led to six recommendations that can be implemented by school districts in collaboration with science teachers to promote constructivist instruction.

    Nam, Jeonghee; Seung, Eulsun; Go, MunSuk

    2013-03-01

    This study investigated how a collaborative mentoring program influenced beginning science teachers' inquiry-based teaching and their reflection on practice. The one-year program consisted of five one-on-one mentoring meetings, weekly science education seminars, weekly mentoring group discussions, and self-evaluation activities. The participants were three beginning science teachers and three mentors at the middle school level (7-9th grades) in an urban area of South Korea. For each beginning teacher, five lessons were evaluated in terms of lesson design/implementation, procedural knowledge, and classroom culture by using the Reformed Teaching Observation Protocol. Five aspects of the beginning teachers' reflections were identified. This study showed that a collaborative mentoring program focusing on inquiry-based science teaching encouraged the beginning teachers to reflect on their own perceptions and teaching practice in terms of inquiry-based science teaching, which led to changes in their teaching practice. This study also highlighted the importance of collaborative interactions between the mentors and the beginning teachers during the mentoring process.

  3. Forensic psychology and correctional psychology: Distinct but related subfields of psychological science and practice.

    2018-02-12

    This article delineates 2 separate but related subfields of psychological science and practice applicable across all major areas of the field (e.g., clinical, counseling, developmental, social, cognitive, community). Forensic and correctional psychology are related by their historical roots, involvement in the justice system, and the shared population of people they study and serve. The practical and ethical contexts of these subfields is distinct from other areas of psychology-and from one another-with important implications for ecologically valid research and ethically sound practice. Forensic psychology is a subfield of psychology in which basic and applied psychological science or scientifically oriented professional practice is applied to the law to help resolve legal, contractual, or administrative matters. Correctional psychology is a subfield of psychology in which basic and applied psychological science or scientifically oriented professional practice is applied to the justice system to inform the classification, treatment, and management of offenders to reduce risk and improve public safety. There has been and continues to be great interest in both subfields-especially the potential for forensic and correctional psychological science to help resolve practical issues and questions in legal and justice settings. This article traces the shared and separate developmental histories of these subfields, outlines their important distinctions and implications, and provides a common understanding and shared language for psychologists interested in applying their knowledge in forensic or correctional contexts.

    2016-04-01

    This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher's reflections on her teaching and her students' learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development.

    In many ways, the physical sciences are at the forefront of using digital tools and methods to work with information and data. However, the fields and disciplines that make up the physical sciences are by no means uniform, and physical scientists find, use, and disseminate information in a variety of ways. This report examines information practices in the physical sciences across seven cases, and demonstrates the richly varied ways in which physical scientists work, collaborate, and share information and data. This report details seven case studies in the physical sciences. For each case, qualitative interviews and focus groups were used to understand the domain. Quantitative data gathered from a survey of participants highlights different information strategies employed across the cases, and identifies important software used for research. Finally, conclusions from across the cases are drawn, and recommendations are made. This report is the third in a series commissioned by the Research Information Network...

    Treves, R. W.

    2007-12-01

    The popularity of projects such as 'Crisis in Darfur' and the IPY (International Polar Year) network link show the potential of using the rich functionality of Virtual Globes for science outreach purposes. However, the structure of outreach projects in Virtual Globes varies widely. Consider an analogy: If you pick up a science journal you immediately know where to find the contents page and what the title and cover story are meant to communicate. That is because journals have a well defined set of norms that they follow in terms of layout and design. Currently, science projects presented in virtual globes have, at best, weakly defined norms, there are little common structural elements beyond those imposed by the constraints of the virtual globe system. This is not a criticism of the science community, it is to be expected since norms take time to develop for any new technology. An example of the development of norms are pages on the web: when they first started appearing structure was unguided but over the last few years structural elements such as a left hand side navigation system and a bread crumb trail near the header have become common. In this paper I shall describe the developing norms of structure I have observed in one area of virtual globe development; Google Earth science outreach projects. These norms include text introductions, video introductions, use of folders and overlay presentation. I shall go on to examine how best to use these norms to build a clear and engaging outreach project and describe some cartographic best practices that we should also consider adopting as norms. I also will briefly explain why I think norms in science outreach aid creativity rather than limiting it despite the counter intuitive nature of this concept.

  10. Assessment of Teaching Methods and Critical Thinking in a Course for Science Majors

    Science.gov (United States)

    Speck, Angela; Ruzhitskaya, L.; Whittington, A. G.

    2014-01-01

    Ability to think critically is a key ingredient to the scientific mindset. Students who take science courses may or may not be predisposed to critical thinking - the ability to evaluate information analytically. Regardless of their initial stages, students can significantly improve their critical thinking through learning and practicing their reasoning skills, critical assessments, conducting and reflecting on observations and experiments, building their questioning and communication skills, and through the use of other techniques. While, there are several of teaching methods that may help to improve critical thinking, there are only a few assessment instruments that can help in evaluating the efficacy of these methods. Critical thinking skills and improvement in those skills are notoriously difficult to measure. Assessments that are based on multiple-choice questions demonstrate students’ final decisions but not their thinking processes. In addition, during the course of studies students may develop subject-based critical thinking while not being able to extend the skills to the general critical thinking. As such, we wanted to design and conduct a study on efficacy of several teaching methods in which we would learn how students’ improve their thinking processes within a science discipline as well as in everyday life situations. We conducted a study among 20 astronomy, physics and geology majors-- both graduate and undergraduate students-- enrolled in our Solar System Science course (mostly seniors and early graduate students) at the University of Missouri. We used the Ennis-Weir Critical Thinking Essay test to assess students’ general critical thinking and, in addition, we implemented our own subject-based critical thinking assessment. Here, we present the results of this study and share our experience on designing a subject-based critical thinking assessment instrument.

    Full Text Available Background: Evidence based medicine (EBM is an approach to improve the quality of clinical decision making, treatment and care provided to patients. This study aimed to assess the knowledge, attitude and practice of faculty members of Alborz University of Medical Sciences about EBM. Methods: A cross sectional study was conducted in 2015 and 40 physicians participated. Data were collected by a valid and reliable structured questionnaire consisting 17 knowledge items, 8 attitude items and 12 items for practices about EBM. Using SPSS software version 19 data analyses was done. Results: From a total of 49 faculty members 40 responded the questionnaires in which 62.5% were female, the mean average age was 40.6 years and mean time of job experience was 8.1 years. About half of the respondents had participated in an EBM workshop, 10% of the participants have stated that do not know EBM and 37.5% had low knowledge, only 7.5% had adequate knowledge. Ninety percent of the respondents believed that EBM has an important role in promoting quality of care and 82% of them were interested to take part in EBM workshops. The information source for clinical practice in 70% of the participants was the text book, 55% Cochrane, and 45% clinical experience. Conclusion: Faculty members had a positive attitude toward EBM; although a vast majority of them claimed that they practice based on evidence in clinical settings, about half of them stated had not adequate knowledge about EBM. Therefore, it is necessary to keep their knowledge up to date.

  17. Health Technology Assessment - science or art?

    Science.gov (United States)

    Hofmann, Bjørn

    2013-01-01

    The founding disciplines of HTA are clearly scientific, and have been firmly based among the natural sciences. However, common definitions of HTA indicate that HTA is something more than the "pure application of science". This article investigates whether this "something" also makes HTA an art. The question of whether HTA is a science or an art is pursued in two specific and historically rich directions. The first is whether HTA is an art in the same way that medicine is described as an art. It has been argued extensively that medicine is based on two different and partly incompatible cultures, i.e., the natural sciences and humanities. Medicine is based on disciplines within the natural sciences, while its value judgments have been placed in the humanities camp. This dichotomy is present in HTA as well, and the first part of the investigation illustrates how HTA is an art in terms of its inherent and constitutive value-judgments. The second part of the science/art-scrutiny leads us to the ancient (Hippocratic) concept of art, téchne, where we find an etymological and a conceptual link between HTA and art. It demonstrates HTA is not an arbitrary process, even though it involves value judgments and relates complex decision making processes. As an art (téchne) HTA has a specific subject matter, requires inquiry and mastery of general rational principles, and is oriented to a specific end. In conclusion, the science-or-art-question makes sense in two specific perspectives, illustrating that HTA is a science based art. This has implications for the practice of HTA, for its education, and for the status of its results.

  18. Risk assessment as rhetorical practice: The ironic mathematics behind terrorism, banking, and public policy.

    Danisch, Robert

    2013-02-01

    The twin problems of possible terrorist attacks and a global economic recession have been, and continue to be, critical components of contemporary political culture. At the center of both problems is the assessment of future risk. To calculate the probability that a loan will default or to estimate the likelihood of an act of bioterrorism crippling an American city is to engage in the quantitative science of risk assessment. The process of risk assessment is an attempt to rationalize the uncertainty and contingency of the future. In this essay, I read risk assessments made by the Department of Homeland Security and by major banks during the recent financial collapse as examples of rhetorical practice. As such, I show the rhetorical form and function of risk assessments in order to determine the effect that they have on contemporary political culture.

    Al-Balushi, Sulaiman M.; Al-Abdali, Nasser S.

    2015-08-01

    This study describes a distance learning professional development program that we designed for the purpose of training science teachers to teach for creativity. The Moodle platform was used to host the training. To ensure that trainees would benefit from this distance learning program, we designed the instructional activities according to the Community of Inquiry framework, which consists of three main elements: cognitive presence, teaching presence and social presence. Nineteen science teachers in Oman engaged in the training, which lasted for 36 working days. To measure the effectiveness of the training program on science teachers' instructional practices related to teaching for creativity, we used a pre-post one-group quasi-experimental design. An observation form was used to assess and document participants' practices. Paired t test results showed that there was a statistically significant improvement in science teachers' practices related to teaching for creativity. During the implementation of the training program, we observed that cognitive presence and teaching presence were the two most successful elements of the program. The training program involved participants in different instructional activities which were designed to help them understand the role of creativity in science; a wide range of instructional techniques designed to nurture students' creativity was discussed. The program also provided participants with opportunities to relate their practices to teaching for creativity and to design and implement lesson plans geared toward teaching for creativity. However, the social presence element was not satisfying. Participants' virtual interactions with each other and their engagement in online discussion forums were limited. This paper provides some recommendations to overcome such pitfalls.

  1. Beginning science teachers' performances: Assessment in times of reform

    Budzinsky, Fie K.

    2000-10-01

    The current reform in science education and the research on effective teaching and student learning have reinforced the importance of teacher competency. To better measure performances in the teaching of science, performance assessment has been added to Connecticut's licensure process for beginning science teachers. Teaching portfolios are used to document teaching and learning over time. Portfolios, however, are not without problems. One of the major concerns with the portfolio assessment process is its subjectivity. Assessors may not have opportunities to ask clarifying or follow-up questions to enhance the interpretation of a teacher's performance. In addition, portfolios often contain components based on self-documentation, which are subjective. Furthermore, the use of portfolios raises test equity issues. These concerns present challenges for persons in charge of establishing the validity of a portfolio-based licensure process. In high-stakes decision processes, such as teaching licensure, the validity of the assessment instruments must be studied. The primary purpose of this study was to explore the criterion-related validity of the Connecticut State Department of Education's Beginning Science Teaching Portfolio by comparing the interpretations of performances from science teaching portfolios to those derived from another assessment method, the Expert Science Teaching Educational and Evaluation Model, (ESTEEM). The analysis of correlations between the Beginning Science Teaching Portfolio and ESTEEM instrument scores was the primary method for establishing support for validity. The results indicated moderate correlations between all Beginning Science Teaching Portfolio and ESTEEM category and total variables. Multiple regression was used to examine whether differences existed in beginning science teachers' performances based on gender, poverty group, school level, and science discipline taught. None of these variables significantly contributed to the

  2. Practice of Regulatory Science (Development of Medical Devices).

    Niimi, Shingo

    2017-01-01

    Prototypes of medical devices are made in accordance with the needs of clinical practice, and for systems required during the initial process of medical device development for new surgical practices. Verification of whether these prototypes produce the intended performance specifications is conducted using basic tests such as mechanical and animal tests. The prototypes are then improved and modified until satisfactory results are obtained. After a prototype passes through a clinical trial process similar to that for new drugs, application for approval is made. In the approval application process, medical devices are divided into new, improved, and generic types. Reviewers judge the validity of intended use, indications, operation procedures, and precautions, and in addition evaluate the balance between risk and benefit in terms of efficacy and safety. Other characteristics of medical devices are the need for the user to attain proficiency in usage techniques to ensure efficacy and safety, and the existence of a variety of medical devices for which assessment strategies differ, including differences in impact on the body in cases in which a physical burden to the body or failure of a medical device develops. Regulatory science of medical devices involves prediction, judgment, and evaluation of efficacy, safety, and quality, from which data result which can become indices in the development stages from design to application for approval. A reduction in the number of animals used for testing, improvement in efficiency, reduction of the necessity for clinical trials, etc. are expected through rational setting of evaluation items.

  3. Assessing the impact participation in science journalism activities has on scientific literacy among high school students

    Science.gov (United States)

    Farrar, Cathy

    As part of the National Science Foundation Science Literacy through Science Journalism (SciJourn) research and development initiative (http://www.scijourn.org ; Polman, Saul, Newman, and Farrar, 2008) a quasi-experimental design was used to investigate what impact incorporating science journalism activities had on students' scientific literacy. Over the course of a school year students participated in a variety of activities culminating in the production of science news articles for Scijourner, a regional print and online high school science news magazine. Participating teachers and SciJourn team members collaboratively developed activities focused on five aspects of scientific literacy: placing information into context, recognizing relevance, evaluating factual accuracy, use of multiple credible sources and information seeking processes. This study details the development process for the Scientific Literacy Assessment (SLA) including validity and reliability studies, evaluates student scientific literacy using the SLA, examines student SLA responses to provide a description of high school students' scientific literacy, and outlines implications of the findings in relation to the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012) and classroom science teaching practices. Scientifically literate adults acting as experts in the assessment development phase informed the creation of a scoring guide that was used to analyze student responses. Experts tended to draw on both their understanding of science concepts and life experiences to formulate answers; paying close attention to scientific factual inaccuracies, sources of information, how new information fit into their view of science and society as well as targeted strategies for information seeking. Novices (i.e., students), in contrast, tended to ignore factual inaccuracies, showed little understanding about source credibility and suggested

    Metrics for assessing adoption of good development practices are a useful way to ensure that software is sustainable, reusable and functional. Sustainability means that the software used today will be available - and continue to be improved and supported - in the future. We report here an initial set of metrics that measure good practices in software development. This initiative differs from previously developed efforts in being a community-driven grassroots approach where experts from different organisations propose good software practices that have reasonable potential to be adopted by the communities they represent. We not only focus our efforts on understanding and prioritising good practices, we assess their feasibility for implementation and publish them here.

    For more than ten years, PUMAS has provided a forum for disseminating peer-reviewed examples of Practical Uses of Math And Science, aimed at helping pre-college teachers enrich their presentation of math and science topics. Contributors include scientists, engineers, and content experts from many disciplines. The innovative ideas in PUMAS examples tend to be treasures, containing the ‘sparks’ of understanding that comes only from having real-life experience with the material. Examples can be essays, anecdotes, problems, demonstrations, or activities, and can be written in any style that serves the material well. They are keyed to the National Standards and Benchmarks, which provide the critical connection to K-12 curriculum guidelines, and the peer-review process involves at least one scientist with a relevant background, and at least one teacher at an appropriate grade level. The PUMAS Web Site has recently been upgraded. It is now a NASA-wide facility, recognized by both the National Science Teachers Association (NSTA) and the National Council of Teachers of Mathematics (NCTM). This presentation will describe and illustrate the operation of PUMAS, will highlight a few of our many treasures, and will appeal to scientists interested in contributing meaningfully to pre-college education to consider submitting examples to PUMAS.

    Savasci, Funda; Berlin, Donna F.

    2012-02-01

    Science teacher beliefs and classroom practice related to constructivism and factors that may influence classroom practice were examined in this cross-case study. Data from four science teachers in two schools included interviews, demographic questionnaire, Classroom Learning Environment Survey (preferred/perceived), and classroom observations and documents. Using an inductive analytic approach, results suggested that the teachers embraced constructivism, but classroom observations did not confirm implementation of these beliefs for three of the four teachers. The most preferred constructivist components were personal relevance and student negotiation; the most perceived component was critical voice. Shared control was the least preferred, least perceived, and least observed constructivist component. School type, grade, student behavior/ability, curriculum/standardized testing, and parental involvement may influence classroom practice.

    Poor quality of sleep is a distressing and worrying condition that can disturb academic performance of medical students. Sleep hygiene practices are one of the important variables that affect sleep quality. The objective of this study was to assess association between sleep hygiene practices and sleep quality of medical students in Qazvin University of Medical Sciences. In this descriptive-correlational study, a total of 285 medical students completed a self-administered questionnaire. Demographic data, sleep-wake schedule in weekday and weekend, and sleep duration were collected. Students' sleep quality was assessed by Pittsburg Sleep Quality Index (PSQI). Data were analyzed by SPSS Ver 13. Overall, 164 (57.5) of students had poor sleep quality. Mean global PSQI score and average score of four subscales were significantly higher in male than female. Regression analysis showed that male students (β=-0.85, Psleep hygiene practices slept worse. The findings of this study showed that the prevalence of poor sleep quality in medical students is high. Improper sleep hygiene behaviors might be a reason for poor quality of sleep in medical students.

    2012-06-01

    Full Text Available In this paper we report an educational experience based on the triad teaching-research-extension occurred in the supervised internship in licentiateship in Biological Sciences. In this experiment, the students made a transposition of the scientific knowledge produced in their course conclusion work to the knowledge of basic education curriculum. We analyze in this article the impressions of undergraduates after completion of pedagogical actions. We discuss, based on the reports, how the knowledge that is constructed and reconstructed in academic research can contribute directly to the improvement of the science education quality through science literacy and also in teacher training of undergraduates, through the reflection on their own practice. Therefore, we consider that, with the practice of the inseparability of teaching-research-extension, there will be more return for academic research and also for the school community, generating significant changes in educational practices in schools

Semi-structured interviews were made to 5 Biology/Geology Master Teachers (MT of primary or secondary education. Two of this 5 MT were deepened studied as examples of good practices through classes’ observation and documental analysis. There were evidences of strong impact of the MC in all interviewed teachers, mainly in the classroom level, as the impact on peers was only evidenced by the two case studies. It is suggested that collaborative practices, involving teachers and researchers, namely as a result of post-graduation contexts, would promote the changing of the existent teachers’ practices.

    Garcia-Alonso, Monica; Raybould, Alan

    2014-12-01

    Policy protection goals are set up in most countries to minimise harm to the environment, humans and animals caused by human activities. Decisions on whether to approve new agricultural products, like pesticides or genetically modified (GM) crops, take into account these policy protection goals. To support decision-making, applications for approval of commercial uses of GM crops usually comprise an environmental risk assessment (ERA). These risk assessments are analytical tools, based on science, that follow a conceptual model that includes a problem formulation step where policy protection goals are considered. However, in most countries, risk assessors face major problems in that policy protection goals set in the legislation are stated in very broad terms and are too ambiguous to be directly applicable in ERAs. This means that risk assessors often have to interpret policy protection goals without clear guidance on what effects would be considered harmful. In this paper we propose a practical approach that may help risk assessors to translate policy protection goals into unambiguous (i.e., operational) protection goals and to establish relevant assessment endpoints and risk hypotheses that can be used in ERAs. Examples are provided to show how this approach can be applied to two areas of environmental concern relevant to the ERAs of GM crops.

    Full Text Available Objectives: To describe pharmacists’ opinions regarding which patient assessment skills are necessary to understand and/or perform to provide optimal patient care in pharmacy practice. Methods: An online questionnaire was distributed to pharmacists licensed in North Carolina (n=14,167, as identified by the Board of Pharmacy. The 80 patient assessment items in the questionnaire were derived from a course text book and faculty experience. Participants indicated whether they “need to understand and be able to perform”, “need to understand only”, or “not need to understand or be able to perform” each item in their current practice setting. Descriptive statistics were used to describe background demographics and perceived need for each item. Post-hoc chi-square analyses were performed to determine differences in need based on practice setting and Pharm.D. degree completion. Results: Of 1036 responses received, 770 were used in data analysis; incomplete questionnaires and non-practicing pharmacist responses were excluded. Fifty-nine percent of respondents held a Pharm.D. degree. Participants identified their practice site(s as inpatient (29%, outpatient (16%, community/retail (50%, long term care (5%, and other (8%. The top five patient assessment items respondents identified as important to understand and perform included automatic blood pressure measurement (63%, point of care testing (57%, manual blood pressure measurement (53%, heart rate measurement (52%, and peak flow meter use (47%. Post-hoc analyses showed a significant difference among those with a Pharm.D. versus those without for the response “need to understand and be able to perform” for 20 patient assessment items; a significant difference was also noted among practice settings for 29 items. Conclusions: The top items pharmacists identified they need to both understand and perform could be applied in various practice settings. The study results may guide which patient

    To respond to increased public and programmatic demand to address underenrollment of clinical translational research studies, the authors examined participant recruitment practices at Clinical and Translational Science Award (CTSA) sites and make recommendations for performance metrics and accountability. The CTSA Recruitment and Retention taskforce in 2010 invited representatives at 46 CTSAs to complete an online 48-question survey querying accrual and recruitment outcomes, practices, evaluation methods, policies, and perceived gaps in related knowledge/practice. Descriptive statistical and thematic analyses were conducted. Forty-six respondents representing 44 CTSAs completed the survey. Recruitment conducted by study teams was the most common practice reported (78%-91%, by study type); 39% reported their institution offered recruitment services to investigators. Respondents valued study feasibility assessment as a successful practice (39%); desired additional resources included feasibility assessments (49%) and participant registries (44%). None reported their institution systematically required justification of feasibility; some indicated relevant information was considered prior to institutional review board (IRB) review (30%) or contract approval (22%). All respondents' IRBs tracked study progress, but only 10% of respondents could report outcome data for timely accrual. Few reported written policies addressing poor accrual or provided data to support recruitment practice effectiveness. Many CTSAs lack the necessary frame work to support study accrual. Recom men dations to enhance accrual include articulating institutional expectations and policy for routine recruitment plan ning; providing recruitment expertise to inform feasibility assessment and recruit ment planning; and developing interdepartmental coordination and integrated informatics infrastructure to drive the conduct, evaluation, and improvement of recruitment practices.

    2016-07-08

    Assessment weighting within a given module can be a motivating factor for students when deciding on their commitment level and time given to study a specific topic. In this study, an analysis of assessment performances of second year anatomy students was performed over four years to determine if (1) students performed better when a higher weighting was given to a set of practical session assessments and (2) whether an improved performance in the practical session assessments had a carry-over effect on other assessment tasks within that anatomy module and/or other anatomy modules that follow. Results showed that increasing the weighting of practical session assessments improved the average mark in that assessment and also improved the percentage of students passing that assessment. Further, it significantly improved performance in the written end-semester examination within the same module and had a carry-over effect on the anatomy module taught in the next teaching period, as students performed better in subsequent practical session assessments as well as subsequent end-semester examinations. It was concluded that the weighting of assessments had significant influences on a student's performance in that, and subsequent, assessments. It is postulated that practical session assessments, designed to develop deep learning skills in anatomy, improved efficacy in student performance in assessments undertaken in that and subsequent anatomy modules when the weighting of these assessments was greater. These deep learning skills were also transferable to other methods of assessing anatomy.

    Development of skills in science communication is a well-acknowledged gap in graduate training, but the constraints that accompany research (limited time, resources, and knowledge of opportunities) make it challenging to acquire these proficiencies. Furthermore, advisors and institutions may find it difficult to support graduate students adequately in these efforts. The result is fewer career and societal benefits because students have not learned to communicate research effectively beyond their scientific peers. To help overcome these hurdles, we developed a practical approach to incorporating broad science communication into any graduate-school time line. The approach consists of a portfolio approach that organizes outreach activities along a time line of planned graduate studies. To help design the portfolio, we mapped available science communication tools according to 5 core skills essential to most scientific careers: writing, public speaking, leadership, project management, and teaching. This helps graduate students consider the diversity of communication tools based on their desired skills, time constraints, barriers to entry, target audiences, and personal and societal communication goals. By designing a portfolio with an advisor's input, guidance, and approval, graduate students can gauge how much outreach is appropriate given their other commitments to teaching, research, and classes. The student benefits from the advisors' experience and mentorship, promotes the group's research, and establishes a track record of engagement. When graduate student participation in science communication is discussed, it is often recommended that institutions offer or require more training in communication, project management, and leadership. We suggest that graduate students can also adopt a do-it-yourself approach that includes determining students' own outreach objectives and time constraints and communicating these with their advisor. By doing so we hope students will

    Martin, Lynn A.

    The purpose of this study was to examine the relationship between teachers' self-reported preparedness for teaching science content and their instructional practices to the science achievement of eighth grade science students in the United States as demonstrated by TIMSS 2007. Six hundred eighty-seven eighth grade science teachers in the United States representing 7,377 students responded to the TIMSS 2007 questionnaire about their instructional preparedness and their instructional practices. Quantitative data were reported. Through correlation analysis, the researcher found statistically significant positive relationships emerge between eighth grade science teachers' main area of study and their self-reported beliefs about their preparedness to teach that same content area. Another correlation analysis found a statistically significant negative relationship existed between teachers' self-reported use of inquiry-based instruction and preparedness to teach chemistry, physics and earth science. Another correlation analysis discovered a statistically significant positive relationship existed between physics preparedness and student science achievement. Finally, a correlation analysis found a statistically significant positive relationship existed between science teachers' self-reported implementation of inquiry-based instructional practices and student achievement. The data findings support the conclusion that teachers who have feelings of preparedness to teach science content and implement more inquiry-based instruction and less didactic instruction produce high achieving science students. As science teachers obtain the appropriate knowledge in science content and pedagogy, science teachers will feel prepared and will implement inquiry-based instruction in science classrooms.

    To describe the phenomenon of final assessment of the clinical practice of nursing students and to examine whether there were differences in assessments by the students and their teachers and mentors. Final assessment of students in clinical practice during their education has great importance for ensuring that enough high-quality nursing students are trained, as assessment tasks affect what the nursing student learns during the clinical practice. This study used descriptive, cross-sectional design. The population of this study comprised nursing students (n = 276) and their teachers (n = 108) in five universities of applied sciences in Finland as well as mentors (n = 225) who came from five partner hospitals. A questionnaire developed for this study contained questions about background variables as well as structured questions scored on a four-point scale, which also allowed the respondents to provide additional comments. When comparing the results related to nursing teachers' presence in the final assessment situation, it was found that teachers and mentors evaluated this as being carried out more often than nursing students suggested. Nursing students noted that fair and consistent assessment is carried out more often than nursing teachers thought. Mentors and teachers said that honest and direct criteria-based final assessment was carried out more often than nursing students evaluated. Nursing students and mentors need support from educational institutions and from nursing teachers in order to ensure the completion of a relevant assessment process. The findings of this study highlight an awareness of final assessment process. It is desirable to have a common understanding, for example, of how the assessment should be managed and what the assessment criteria are, as this will ensure a good quality process. © 2017 John Wiley & Sons Ltd.

    Sangueza, Cheryl Ramirez

    This mixed-method, dual-phase, embedded-case study employed the Social Cognitive Theory and the construct of self-efficacy to examine the contributors to science teaching self-efficacy and science teaching practices across different levels of efficacy in six pre-service elementary teachers during their science methods course and student teaching experiences. Data sources included the Science Teaching Efficacy Belief Instrument (STEBI-B) for pre-service teachers, questionnaires, journals, reflections, student teaching lesson observations, and lesson debriefing notes. Results from the STEBI-B show that all participants measured an increase in efficacy throughout the study. The ANOVA analysis of the STEBI-B revealed a statistically significant increase in level of efficacy during methods course, student teaching, and from the beginning of the study to the end. Of interest in this study was the examination of the participants' science teaching practices across different levels of efficacy. Results of this analysis revealed how the pre-service elementary teachers in this study contextualized their experiences in learning to teach science and its influences on their science teaching practices. Key implications involves the value in exploring how pre-service teachers interpret their learning to teach experiences and how their interpretations influence the development of their science teaching practices.

    2012-12-01

    A solid understanding of timescales is crucial for any climate change discussion. This hands-on lab was designed as part of a dual-credit climate change course in which high school students can receive college credit. Using homemade ice cores, students have the opportunity to participate in scientific practices associated with collecting, processing, and interpreting temperature and CO2 data. Exploring millennial-scale cycles in ice core data and extending the CO2 record to the present allows students to discover timescales from an investigators perspective. The Ice Core Lab has been piloted in two high school classrooms and student engagement, and epistemological and conceptual understanding was evaluated using quantitative pre and post assessment surveys. The process of creating this lab involved a partnership between an education assessment professional, high school teachers, and University of Washington professors and graduate students in Oceanography, Earth and Space Sciences, Atmospheric Sciences and the Learning Sciences as part of the NASA Global Climate Change University of Washington in the High School program. This interdisciplinary collaboration led to the inception of the lab and was necessary to ensure that the lesson plan was pedagogically appropriate and scientifically accurate. The lab fits into a unit about natural variability and is paired with additional hands-on activities created by other graduate students that explore short-timescale temperature variations, Milankovitch cycles, isotopes, and other proxies. While the Ice Core Lab is intended to follow units that review the scientific process, global energy budget, and transport, it can be modified to fit any teaching platform.

    2004-09-01

    In this paper, we report work undertaken with a group of 11 UK teachers over a period of a year to teach aspects of the nature of science, its process, and its practices. The teachers, who taught science in a mix of elementary, junior high, and high schools, were asked to teach a set of ideas-about-scienc for which consensual support had been established using a Delphi study in the first phase of the project. Data were collected through field notes, videos of the teachers' lessons, teachers' reflective diaries, and instruments that measured their understanding of the nature of science and their views on the role and value of discussion in the classroom. In this paper, drawing on a sample of the data we explore the factors that afforded or inhibited the teachers' pedagogic performance in this domain. Using these data, we argue that there are five critical dimensions that distinguish and determine a teacher's ability to teach effectively about science. Whilst these dimensions are neither mutually independent nor equally important, they serve as a valuable analytical tool for evaluating and explaining the success, or otherwise, that individual teachers of science have when confronted with teaching aspects about science. In addition, we argue that they are an important means of identifying salient aspects of pedagogy for initial and in-service training of science teachers for curricula that incorporate elements of ideas-about-science

    Full Text Available Objective and Setting: As universities and libraries grapple with data management and “big data,” the need for data management solutions across disciplines is particularly relevant in clinical and translational science (CTS research, which is designed to traverse disciplinary and institutional boundaries. At the University of Florida Health Science Center Library, a team of librarians undertook an assessment of the research data management needs of CTS researchers, including an online assessment and follow-up one-on-one interviews. Design and Methods: The 20-question online assessment was distributed to all investigators affiliated with UF’s Clinical and Translational Science Institute (CTSI and 59 investigators responded. Follow-up in-depth interviews were conducted with nine faculty and staff members. Results: Results indicate that UF’s CTS researchers have diverse data management needs that are often specific to their discipline or current research project and span the data lifecycle. A common theme in responses was the need for consistent data management training, particularly for graduate students; this led to localized training within the Health Science Center and CTSI, as well as campus-wide training. Another campus-wide outcome was the creation of an action-oriented Data Management/Curation Task Force, led by the libraries and with participation from Research Computing and the Office of Research. Conclusions: Initiating conversations with affected stakeholders and campus leadership about best practices in data management and implications for institutional policy shows the library’s proactive leadership and furthers our goal to provide concrete guidance to our users in this area.

    Overinclusive authorship practices such as honorary or guest authorship have been widely reported, and they appear to be exacerbated by the rise of large interdisciplinary collaborations that make authorship decisions particularly complex. Although many studies have reported on the frequency of honorary authorship and potential solutions to it, few have probed how the underlying dynamics of large interdisciplinary teams contribute to the problem. This article reports on a qualitative study of the authorship standards and practices of six National Science Foundation-funded interdisciplinary environmental science teams. Using interviews of the lead principal investigator and an early-career member on each team, our study explores the nature of honorary authorship practices as well as some of the motivating factors that may contribute to these practices. These factors include both structural elements (policies and procedures) and cultural elements (values and norms) that cross organizational boundaries. Therefore, we provide recommendations that address the intersection of these factors and that can be applied at multiple organizational levels.

    2015-08-05

    The analysis of substances of abuse remains one of the most matured areas in forensic science with a strong scientific basis, namely analytical chemistry. The current evolving drug markets, characterized by the global emergence of new psychoactive substances (NPS) and the need for forensic scientists to identify an unprecedented and ever-increasing number of NPS, presents a unique challenge to this discipline. This article looks at the current situation with NPS at the global level, and the challenges posed to the otherwise technically robust forensic science discipline of analysis of substances of abuse. It discusses the preparedness of forensic science to deal with the current situation and identifies the need for a shift in forensic science practice, especially one which embraces research and looks beyond normal casework in order to provide the much needed data for developing effective policy responses to the NPS problem. © 2015 The Author(s) Published by the Royal Society.

  19. Aerosol science: theory and practice

    International Nuclear Information System (INIS)

    Williams, M.M.R.; Loyalka, S.K.

    1991-01-01

    The purpose of this book is twofold. First, it is intended to give a thorough treatment of the fundamentals of aerosol behavior with rigorous proofs and detailed derivations of the basic equations and removal mechanisms. Second, it is intended to provide practical examples with special attention to radioactive particles and their distribution in size following a radioactive release arising from an accident with a nuclear system. We start with a brief introduction to the applications of aerosol science and the characteristics of aerosols in Chapter 1. In Chapter 2, we devote considerable attention to single and two particle motion with respect to both translation and rotation. Chapter 3 contains extensive discussion of the aerosol general dynamical equation and the dependences of aerosol distributions on size, shape, space, composition, radioactivity, and charge. Important particle rate processes of coagulation, condensation, and deposition/resuspension are discussed in the chapters 4, 6 and 7, respectively. In Chapter 5, we provide a thorough treatment of the analytical and numerical methods used in solving the various forms of the aerosol dynamical equation. We discuss the importance and applications of aerosol science to nuclear technology and, in particular, the nuclear source term in Chapter 8. Our focus in this chapter is on discussions of nuclear accidents that can potentially release large amount of radioactivity to environment. We also discuss the progress that has been made in understanding the natural and engineered aerosol processes that limit or affect such releases. (author)

    Environmental enrichment in zoos and aquariums is often evaluated at two overlapping levels: published research and day-to-day institutional record keeping. Several authors have discussed ongoing challenges with small sample sizes in between-groups zoological research and have cautioned against the inappropriate use of inferential statistics (Shepherdson, , International Zoo Yearbook, 38, 118-124; Shepherdson, Lewis, Carlstead, Bauman, & Perrin, Applied Animal Behaviour Science, 147, 298-277; Swaisgood, , Applied Animal Behaviour Science, 102, 139-162; Swaisgood & Shepherdson, , Zoo Biology, 24, 499-518). Multi-institutional studies are the typically-prescribed solution, but these are expensive and difficult to carry out. Kuhar ( Zoo Biology, 25, 339-352) provided a reminder that inferential statistics are only necessary when one wishes to draw general conclusions at the population level. Because welfare is assessed at the level of the individual animal, we argue that evaluations of enrichment efficacy are often instances in which inferential statistics may be neither necessary nor appropriate. In recent years, there have been calls for the application of behavior-analytic techniques to zoo animal behavior management, including environmental enrichment (e.g., Bloomsmith, Marr, & Maple, , Applied Animal Behaviour Science, 102, 205-222; Tarou & Bashaw, , Applied Animal Behaviour Science, 102, 189-204). Single-subject (also called single-case, or small-n) designs provide a means of designing evaluations of enrichment efficacy based on an individual's behavior. We discuss how these designs might apply to research and practice goals at zoos and aquariums, contrast them with standard practices in the field, and give examples of how each could be successfully applied in a zoo or aquarium setting. © 2017 Wiley Periodicals, Inc.

  1. The 'grey' assessment practice of IA screening

    Bidstrup, Morten

    2017-01-01

    Research focusing on the practices surrounding screening in Impact Assessment (IA) is limited. Yet, it has been found that development proposals sometimes are adjusted through an informal dialog with IA practitioners prior to or during screening. Such practice is often referred to as ‘grey IA......’ in Denmark. This article explores the prevalence, influence and applied rationale of grey IA. Through a questionnaire, data was collected from 121 IA practitioners working within the fields of environmental impact assessment and strategic environmental assessment. It was found that grey IA is a common...... practice, which influences the outcomes of formal screening procedures through consideration of impacts on neighbours and spatial zones of protection. Grey IA is to some extent motivated by the opportunity to save the resources required for full-scale IA, but an additional ‘green’ rationale also exists...

    This study examined Chinese and US middle-school science teachers' perceptions of autonomy support. Previous research has documented the link between teachers' perceptions of autonomy and the use of student-oriented teaching practices for US teachers. But is not clear how the perception of autonomy may differ for teachers from different cultures or more specifically how motivation factors differ across cultures. The survey measured teachers' motivation, perceptions of constraints at work, perceptions of students' motivation, and level of autonomy support for students. Exploratory factor analysis of responses for the combined teacher sample (n = 201) was carried out for each of the survey assessments. Significance testing for Chinese (n = 107) and US (n = 94) teachers revealed significant differences in teachers' motivation and perceptions of constraints at work and no significant differences for perceptions of students' motivation or their level of autonomy support for students. Chinese teachers' perceptions of constraints at work, work motivation, and perceptions of student motivation were found to significantly predict teachers' autonomy support. For the US teachers, teacher motivation was the only significant predictor of teachers' autonomy support. A sub-sample of teachers (n = 19) was interviewed and results showed that teachers in both countries reported that autonomy was important to their motivation and the quality of science instruction they provided to students. The primary constraints on teaching reported by the US teachers related to materials and laboratory space while the Chinese teachers reported constraints related to the science curriculum and standards.

    2018-03-01

    From a sociocultural perspective, I discuss data from a Swedish science classroom presented in María Gómez's article "Student Explanations of their Science Teachers' Assessments, Grading Practices, and How they learn Science". In this discussion, I focus on the need to change existing conceptions of assessment in the teaching and learning of science. Next, I talk about the importance of taking into consideration the dialectic between agency and passivity as filters in order to understand what student silence may signify in science classes as well as in relation to their perceptions of assessment. I conclude with the importance of the teacher's role in developing formative assessment, along with the challenges in developing assessments which transform science education into a relevant field of knowledge for both students and society at large.

  5. Teachers' instructional goals for science practice: Identifying knowledge gaps using cultural-historical activity theory (CHAT)

    Science.gov (United States)

    Farrar, Cynthia Hamen

    In AP Biology, the course goal, with respect to scientific acts and reasoning, has recently shifted toward a reform goal of science practice, where the goal is for students to have a scientific perspective that views science as a practice of a community rather than a body of knowledge. Given this recent shift, this study is interested in the gaps that may exist between an individual teacher's instructional goal and the goals of the AP Biology course. A Cultural-Historical Activity Theory (CHAT) methodology and perspective is used to analyze four teachers' knowledge, practice, and learning. Teachers have content knowledge for teaching, a form of knowledge that is unique for teaching called specialized content knowledge. This specialized content knowledge (SCK) defines their instructional goals, the student outcomes they ultimately aim to achieve with their students. The study employs a cultural-historical continuum of scientific acts and reasoning, which represents the development of the AP Biology goal over time, to study gaps in their instructional goal. The study also analyzes the contradictions within their teaching practice and how teachers address those contradictions to shift their instructional practice and learn. The findings suggest that teachers have different interpretations of the AP Biology goals of science practice, placing their instructional goal at different points along the continuum. Based on the location of their instructional goal, different micro-communities of teachers exist along the continuum, comprised of teachers with a shared goal, language, and culture of their AP Biology teaching. The in-depth study of one teacher's AP Biology teaching, using a CHAT perspective, provides a means for studying the mechanisms that connect SCK to classroom actions and ultimately to instructional practice. CHAT also reveals the nature and importance of contradictions or cognitive dissonance in teacher learning and the types of support teachers need to

    The family medicine residency behavioral science curriculum is more effective if prioritized to match what is needed in practice after graduation. Two prior studies (Kendall, Marvel, & Cruickshank, 2003; Marvel & Major, 1999) identified physician priorities for behavioral science education. The present study extends this research to include topics from more recent curriculum guidelines and examines the extent to which size of community and perceived competence correlate with prioritization of Washington state family physicians. Practicing family physicians in Washington state (N = 2,270) were invited to complete the survey. Respondents provided demographic and practice information. Respondents then rated, on a scale from 1 to 4, 35 behavioral science topics on 2 different scales including (a) priority to be given in residency education and (b) perceived level of competence. A total of 486 responded and 430 completed both priority and competence scales for a response rate of 19%. The top half of 35 topics of the present study included the top 13 topics found in the 2 prior studies. Priority and competence scales were moderately correlated (r = .48, n = 430, p = .001). There was a small significant correlation with size of community and priority ratings (r = .13, n = 435, p = .006). Family physicians in Washington state prioritize behavioral science topics in residency education similar to Colorado and Mississippi. The results of this study support recent ACGME guidelines, in that training should focus on common psychiatric illnesses, including depression and anxiety, and interpersonal processes.

    2013-12-01

    Earth Science research data, its data management, informatics processing and its data curation are valuable in allowing earth scientists to make new discoveries. But how to actively manage these research assets to ensure them safe and secure, accessible and reusable for long term is a big challenge. Nowadays, the data deluge makes this challenge become even more difficult. To address the growing demand for managing earth science data, the Council on Library and Information Resources (CLIR) partners with the Library and Technology Services (LTS) of Lehigh University and Purdue University Libraries (PUL) on hosting postdoctoral fellows in data curation activity. This inter-disciplinary fellowship program funded by the SLOAN Foundation innovatively connects university libraries and earth science departments and provides earth science Ph.D.'s opportunities to use their research experiences in earth science and data curation trainings received during their fellowship to explore best practices for research data management in earth science. In the process of exploring best practices for data curation in earth science, the CLIR Data Curation Fellows have accumulated rich experiences and insights on the data management behaviors and needs of earth scientists. Specifically, Ting Wang, the postdoctoral fellow at Lehigh University has worked together with the LTS support team for the College of Arts and Sciences, Web Specialists and the High Performance Computing Team, to assess and meet the data management needs of researchers at the Department of Earth and Environmental Sciences (EES). By interviewing the faculty members and graduate students at EES, the fellow has identified a variety of data-related challenges at different research fields of earth science, such as climate, ecology, geochemistry, geomorphology, etc. The investigation findings of the fellow also support the LTS for developing campus infrastructure for long-term data management in the sciences.

    Full Text Available This study analyzes the science process skills in West African senior secondary school certificate physics practical examinations in Nigeria for a period of 10 years (1998-2007. Ex-post facto design was adopted for the study. The 5 prominent science process skills identified out of the 15 used in the study are: manipulating (17%, calculating (14%, recording (14%, observing (12% and communicating (11%. The results also show high percentage rate of basic (lower order science process skills (63% as compared to the integrated (higher order science process skills (37%. The results also indicate that the number of basic process skills is significantly higher than the integrated process skills in the West African senior secondary school certificate physics practical examinations in Nigeria. It is recommended that the examination bodies in Nigeria should include more integrated science process skills into the senior secondary school physics practical examinations so as to enable the students to be prone to creativity, problem solving, reflective thinking, originality and invention which are vital ingredients for science and technological development of any nation.

    Responsiveness to citizens as users of technological innovation helps motivate translational research and commercial engagement among academics. Yet, retaining citizen trust and support for research encourages caution in pursuit of commercial science. We explore citizen expectations of the specifically academic nature of commercial science [i.e. academic entrepreneurship (AE)] and the influence of conflict of interest concerns, hopes about practical benefits and general beliefs. We conducted a cross-sectional national opinion survey of 1002 Canadians online in 2010. Approval of AE was moderate (mean 3.2/5, SD 0.84), but varied by entrepreneurial activity. Concern about conflict of interests (COI) was moderate (mean 2.9/5, SD 0.86) and varied by type of concern. An ordinary least-squares regression showed that expectations of practical benefits informed support for AE, specifically that academic-industry collaboration can better address real-world problems; conflict of interest concerns were insignificant. These findings suggest that citizens support AE for its potential to produce practical benefits, but enthusiasm varies and is reduced for activities that may prioritize private over public interests. Further, support exists despite concern about COI, perhaps due to trust in the academic research context. For user engagement in research priority setting, these findings suggest the need to attend to the commercial nature of translational science. For research policy, they suggest the need for governance arrangements for responsible innovation, which can sustain public trust in academic research, and realize the practical benefits that inform public support for AE. © 2014 John Wiley & Sons Ltd.

    2018-04-01

    Information on students' development of science skills is essential for teachers to evaluate and improve their own education, as well as to provide adequate support and feedback to the learning process of individual students. The present study explores and discusses the use of performance assessments as a diagnostic tool for formative assessment to inform teachers and guide instruction of science skills in primary education. Three performance assessments were administered to more than 400 students in grades 5 and 6 of primary education. Students performed small experiments using real materials while following the different steps of the empirical cycle. The mutual relationship between the three performance assessments is examined to provide evidence for the value of performance assessments as useful tools for formative evaluation. Differences in response patterns are discussed, and the diagnostic value of performance assessments is illustrated with examples of individual student performances. Findings show that the performance assessments were difficult for grades 5 and 6 students but that much individual variation exists regarding the different steps of the empirical cycle. Evaluation of scores as well as a more substantive analysis of students' responses provided insight into typical errors that students make. It is concluded that performance assessments can be used as a diagnostic tool for monitoring students' skill performance as well as to support teachers in evaluating and improving their science lessons.

    With at least 150 million professional and amateur blogs on the Internet, blogging offers a potentially powerful tool for engaging large and diverse audiences with science. This article investigates science blogging practices to uncover key trends, including bloggers' self-perceptions of their role. Interviews with seven of the most popular science bloggers revealed them to be driven by intrinsic personal motivations. Wishing to pursue their love of writing and share their passion for science, they produce content suitable for niche audiences of science enthusiasts, although they do not assume background scientific knowledge. A content analysis of 1000 blog posts and comparison with the most popular blogs on the Internet further confirmed this result and additionally identified key factors that affect science blog popularity, including update frequency, topic diversity and the inclusion of non-text elements (especially images and video). © The Author(s) 2014.

    Mumma, Brian

    Statement of the problem. Science education literature had agreed that an important goal in students' learning is the development of scientific and technological literacy. One effort that teachers have integrated into their practices for addressing this goal has been teaching within the contexts of Internet Science Projects. Greater awareness of teachers' perspectives of their best practices and their beliefs and reasons for these practices in the contexts of Internet Science Projects can improve the quality of science education programs. Methods. A series of pilot interviews was conducted during the 2000--2001 school year to develop the guiding questions for inquiring into teachers' perspectives of their best practices within the contexts of Internet Science Projects. This series of interviews resulted in the understanding of the need to select teachers with experiences with Internet Science Projects and to conduct in-depth phenomenological interviews for learning from their voices. Two teachers were purposefully selected as the participant-informants for this study, one an American elementary teacher from Walker County, Georgia, and one a Russian teacher from St. Petersburg, Russia. The study was conducted from October through December 2001. The data collected for this qualitative study consisted of a series of in-depth phenomenological interviews, classroom observations, and the collection and analysis of various artifacts including teacher journals, student products, and e-mail/bulletin board transcripts. The interview structure was based upon a modification of expanding Seidman's (1998) three interview series into multiple interviews concluded upon the determination of saturation of the topic. The series of interviews were composed of (1) life history focus; (2) the details of the experience of teaching within the contexts of Internet Science Projects; and (3) reflection on the meanings. The data analysis consisted of applying Strauss & Corbin's (1990) open

  2. Practice or Theory: Situating Science Teacher Preparation Within a Context of Ecojustice Philosophy

    Science.gov (United States)

    Britton, Stacey A.; Tippins, Deborah J.

    2015-06-01

    Theory is taught to preservice teachers from the moment they enter the education program until they graduate. While theory serves as the foundation in many teacher preparation courses, these future teachers must also understand the relationship it has to practice. The focus of this article is on the journey of one group of preservice secondary science teachers toward becoming practitioners with a theoretical understanding of what and how they would teach science. Ecojustice philosophy, being implemented through citizen science pedagogy, served as the framework for this method course and proved challenging for both the professor and the preservice teacher. Hermeneutic ethnography served as the guiding methodological/theoretical framework for this research and provided an opportunity for extensive data collection in an attempt to better understand how participants made sense of learning to teach within a method course focused around ecojustice philosophy. By using hermeneutic ethnography, we are encouraged to make sense of what we are seeing, while considering our own cultural experiences and abilities to interact with others taking part in these events. This research highlights the need for dialogue within science teacher preparation classrooms, addresses the challenges in teaching for practice-theory, and suggests possibilities for future considerations within science teacher preparation.

  3. The impact of professional development on classroom teaching for science educators participating in a long term community of practice

    Science.gov (United States)

    Jensen, Aaron C.

    Efforts to modify and improve science education in the United States have seen minimal success (Crawford, 2000; Borko & Putman, 1996; Puntambekar, Stylianou & Goldstein, 2007; Lustick, 2011). One important reason for this is the professional development that teachers go through in order to learn about and apply these new ideas is generally of poor quality and structured incorrectly for long-term changes in the classroom (Little, 1993; Fullen, 1996; Porter, 2000; Jeanpierre, Oberhauser, & Freeman, 2005). This grounded theory study explores a science community of practice and how the professional development achieved through participation in that community has effected the instruction of the teachers involved, specifically the incorporation of researched based effective science teaching instructional strategies. This study uses personal reflection papers written by the participants, interviews, and classroom observations to understand the influence that the science community of practice has had on the participants. Results indicate that participation in this science community of practice has significant impact on the teachers involved. Participants gained greater understanding of science content knowledge, incorporated effective science instructional strategies into their classroom, and were able to practice both content knowledge and strategies in a non-threatening environment thus gaining a greater understanding of how to apply them in the classrooms. These findings motivate continued research in the role that communities of practice may play in teacher professional develop and the effectiveness of quality professional development in attaining long-term, sustained improvement in science education.

    An evaluation of the Integrated Practice Model for Forensic Nursing Science () is presented utilizing methods outlined by . A brief review of nursing theory basics and evaluation methods by Meleis is provided to enhance understanding of the ensuing theoretical evaluation and critique. The Integrated Practice Model for Forensic Nursing Science, created by forensic nursing pioneer Virginia Lynch, captures the theories, assumptions, concepts, and propositions inherent in forensic nursing practice and science. The historical background of the theory is explored as Lynch's model launched the role development of forensic nursing practice as both a nursing and forensic science specialty. It is derived from a combination of nursing, sociological, and philosophical theories to reflect the grounding of forensic nursing in the nursing, legal, psychological, and scientific communities. As Lynch's model is the first inception of forensic nursing theory, it is representative of a conceptual framework although the title implies a practice theory. The clarity and consistency displayed in the theory's structural components of assumptions, concepts, and propositions are analyzed. The model is described and evaluated. A summary of the strengths and limitations of the model is compiled followed by application to practice, education, and research with suggestions for ongoing theory development.

  9. “Which Child Left Behind”: Historical Issues Regarding Equity in Science Assessment

    Directory of Open Access Journals (Sweden)

    J. Joy Cumming

    2013-08-01

    Full Text Available Assessment of learning plays a dominant role in formal education in the forms of determining features of curriculum that are emphasized, pedagogic methods that teachers use with their students, and parents’ and employers’ understanding of how well students have performed. A common perception is that fair assessment applies the same mode of assessment and content focus for all students—the approach of assessments in international comparative studies of science achievement. This article examines research evidence demonstrating that the act of assessment is not neutral—different forms of assessment advantage or disadvantage groups of students on the basis of family backgrounds, gender, race, or disability. Assessment that implicitly or explicitly captures the social capital of the child serves to consolidate, not address, educational equity. The article provides an overview of ways that science curriculum focus and assessment can introduce bias in the identification of student achievement. It examines the effect of changes to curriculum and assessment approaches in science, and relationships between assessment of science and the cultural context of the student. Recommendations are provided for science–assessment research to address bias for different groups of students.

    Full Text Available Current researches into teacher formation show different aspects in their approaches. To teach science, a professional is required to have more than knowledge of the contents and possession of good didactic skills. Teacher formation (initial and continued is a broad problem, and a challenge, facing the innumerous questions already raised by experienced professionals in this field. Our research is directed at permanent teacher formation (initial and continued, giving priority to the relationship between DOING SCIENCE and TEACHING SCIENCE (VIANNA, 1998, while attempting to compare scientists practice at laboratories with teachers’ science. We analyzed a refresher course for High School teachers of Biology in Rio de Janeiro. We highlighted the parts of this course that took place in research laboratories, which we refer to as “research episodes,” showing what participants gained from this experience: knowledge about scientists’ practices, what they do, what they say, how they behave, how they interact, what they build, what they publish in their articles and why, that is: TO EXPERIENCE DAILY SCIENTIFIC PRACTICE. We looked at these “episodes” according to LATOUR and WOOLGAR (1988, 1989, 1994, 1995, 1997. The teachers who attended the course were queried about its influence on their teaching formation. They emphasized the perception they gained about how scientific knowledge is built, the passion researchers have for their activity, the new technologies and instruments used nowadays, and their desire to adopt a new approach in the classroom. Our work points out the need for a permanent teacher formation, establishing an analogy between scientific and pedagogic research with teaching practice.

  11. Second-career science teachers' classroom conceptions of science and engineering practices examined through the lens of their professional histories

    Antink-Meyer, Allison; Brown, Ryan A.

    2017-07-01

    Science standards in the U.S. have shifted to emphasise science and engineering process skills (i.e. specific practices within inquiry) to a greater extent than previous standards' emphases on broad representations of inquiry. This study examined the alignment between second-career science teachers' personal histories with the latter and examined the extent to which they viewed that history as a factor in their teaching. Four, second-career science teachers with professional backgrounds in engineering, environmental, industrial, and research and development careers participated. Through the examination of participants' methodological and contextual histories in science and engineering, little evidence of conflict with teaching was found. They generally exemplified the agency and motivation of a second-career teacher-scientist that has been found elsewhere [Gilbert, A. (2011). There and back again: Exploring teacher attrition and mobility with two transitioning science teachers. Journal of Science Teacher Education, 22(5), 393-415; Grier, J. M., & Johnston, C. C. (2009).

    Kundur, P; Gao, B [Powertech Labs. Inc., Surrey, BC (Canada)

    1994-12-31

    This paper deals with some of the most important practical issues related to voltage stability assessment of large practical systems. A brief discussion of the practical aspects of voltage stability problem and prevention of voltage instability is given first, followed by descriptions of different analytical techniques and tools for voltage stability analysis. Presentations of analytical tools is focused on the VSTAB program which incorporates the modal analysis, continuation power flow, and shortest distance to instability techniques, Finally, an example case study of a practical large system is presented. The case study illustrates how modal analysis is used to determine the most effective load shedding scheme for preventing voltage instability. (author) 15 refs., 2 figs., 2 tabs.

  13. The nature of science and the preservice elementary teacher: Changes in understanding and practice

    Rivas, Michael Gerald

    This action research project studies preservice elementary teachers in a science methods course. The purpose of this research project was to enhance preservice teachers' understanding of specific nature of science (NOS) tenets so as to promote equity and access within the elementary science classroom. In particular, I chose five NOS tenets that were listed in the first chapter of the AAAS (1989) document titled, "The Nature of Science," and connected them to equitable educational goals and practices. The theoretical framework guiding this study came from bodies of scholarship relating to the NOS, social constructivism, and action research. This study addressed the following three questions: (1) What opportunities were provided the preservice teachers so that they could enhance their understandings of the NOS? (2) What were the changes in preservice teachers' understanding of the NOS as a result? (3) How did the prospective teachers' understandings of the NOS translate into their classroom practice? The analysis revealed that the science methods course's operational curriculum consisted of implicit and explicit teaching of the NOS, as well as intended and untended NOS tenets. The prospective teachers initially held a limited view of the NOS, but by the end of the course their view had been enhanced. In addition, the participants made direct connections between their new understandings of the NOS and equity and access in the science classroom. In their teaching, the preservice teachers as a group implicitly taught all five of the NOS tenets. In fact, a majority taught three of the five intended tenets. Explicitly, only one tenet was taught, but it was taught with a direct connection to making the science classroom more inclusive. The findings of this study indicate that preservice teachers can have their views of the NOS enhanced even though they may have experienced years of deficient science instruction. They pointed out that this enhanced view of the NOS can be

    2016-12-01

    Just as the Next Generation Science Standards (NGSSs) call for change in what students learn and how they are taught, teacher education programs must reconsider courses and curriculum in order to prepare teacher candidates to understand and implement new standards. In this study, we examine the development of prospective elementary teachers' practical knowledge of the NGSS in the context of a science methods course and innovative field experience. We present three themes related to how prospective teachers viewed and utilized the standards: (a) as a useful guide for planning and designing instruction, (b) as a benchmark for student and self-evaluation, and (c) as an achievable vision for teaching and learning. Our findings emphasize the importance of collaborative opportunities for repeated teaching of the same lessons, but question what is achievable in the context of a semester-long experience.

  16. The Nature and Influence of Teacher Beliefs and Knowledge on the Science Teaching Practice of Three Generalist New Zealand Primary Teachers

    Science.gov (United States)

    Anderson, Dayle

    2015-06-01

    Students' negative experiences of science in the primary sector have commonly been blamed on poor teacher content knowledge. Yet, teacher beliefs have long been identified as strong influences on classroom practice. Understanding the nature of teacher beliefs and their influence on primary science teaching practice could usefully inform teacher development initiatives. In science education, teacher beliefs about teaching and learning have been proposed as key influences in the development of pedagogical content knowledge for science teaching. This paper uses a multiple qualitative case study design to examine the nature and influence of beliefs on the practice and knowledge development of three generalist primary teachers during the implementation of a unit of work in science. Data for each case study included observations and transcripts of recordings of the lessons forming each science unit, together with multiple interviews with the teacher throughout its implementation. Findings support those of other researchers suggesting that beliefs about purposes of science education, the nature of science, and science teaching and learning strongly influence teacher practice and knowledge. Beliefs about the purposes of science education were found to be a particularly strong influence on practice in the observed cases. However, beliefs about students and the teachers' aims for education generally, as well as teachers' notions concerning vertical science curriculum, were also crucially influential on the type of science learning opportunities that were promoted. Beliefs were found to additionally influence the nature of both subject matter knowledge and pedagogical content knowledge for science developed by the teachers.

  18. Kindergarten girls "illuminating" their identities-in-practice through science instruction framed in explanation building: From the shadows into the light

    Science.gov (United States)

    McDyre, Alicia M.

    Recent research on young children's learning has revealed that they are capable of sophisticated scientific reasoning and has prompted a new era of reform framed around the integration of three main strands -- core disciplinary ideas, scientific and engineering practices, and cross-cutting themes. Given the documented issues with girls in science in later grades, I chose to examine their participation in scientific norms and practices in kindergarten to gain insights into their identities-in-practice. From the perspective of identity as an enactment of self, I used the lens identities-in-practice (Lave & Wenger, 1991) to examine the impact that having classroom science instruction framed around constructing explanations with evidence would have on the girls in the class. In this study, I drew from theories of sociocultural learning, positioning, and identities-in-practice to study: a) the norms of participation, b) the authoring and positioning of girls, and c) the identities-in-practice that the girls' enacted in the kindergarten science classroom. Using a research design informed by qualitative methods and participant observation, I analyzed data using a constant comparative approach and crafted case studies of four girls in the science classroom. Three assertions were generated from this study: a) Identity-in-practice manifests differently in different literacy practices and shows how students chose to be science students across time and activities- a focus on one literacy practice alone is insufficient to understand identity; b) The ways in which the teacher positions girls, especially "quiet" girls, is essential for engaging them in productive participation in science discourse and learning; and c) A focus on classroom science instruction grounded in constructing explanations from evidence provided a consistent framework for students' writing and talking, which facilitated the establishment of expectations and norms of participation for all students

    There are increasing numbers of randomised trials and systematic reviews examining the efficacy of interventions designed to bring about a change in clinical practice. The findings of this research are being used to guide strategies to increase the uptake of evidence into clinical practice. Knowledge of the outcomes measured by these trials is vital not only for the interpretation and application of the work done to date, but also to inform future research in this expanding area of endeavour and to assist in collation of results in systematic reviews and meta-analyses. The objective of this review was to identify methods used to measure change in the clinical practices of health professionals following an intervention aimed at increasing the uptake of evidence into practice. All published trials included in a recent, comprehensive Health Technology Assessment of interventions to implement clinical practice guidelines and change clinical practice (n = 228) formed the sample for this study. Using a standardised data extraction form, one reviewer (SH), extracted the relevant information from the methods and/or results sections of the trials. Measures of a change of health practitioner behaviour were the most common, with 88.8% of trials using these as outcome measures. Measures that assessed change at a patient level, either actual measures of change or surrogate measures of change, were used in 28.8% and 36.7% of studies (respectively). Health practitioners' knowledge and attitudes were assessed in 22.8% of the studies and changes at an organisational level were assessed in 17.6%. Most trials of interventions aimed at changing clinical practice measured the effect of the intervention at the level of the practitioner, i.e. did the practitioner change what they do, or has their knowledge of and/or attitude toward that practice changed? Less than one-third of the trials measured, whether or not any change in practice, resulted in a change in the ultimate end-point of

    Publishing scholarly articles in traditional and newly-launched journals is a responsible task, requiring diligence from authors, reviewers, editors, and publishers. The current generation of scientific authors has ample opportunities for publicizing their research. However, they have to selectively target journals and publish in compliance with the established norms of publishing ethics. Over the past few years, numerous illegitimate or predatory journals have emerged in most fields of science. By exploiting gold Open Access publishing, these journals paved the way for low-quality articles that threatened to change the landscape of evidence-based science. Authors, reviewers, editors, established publishers, and learned associations should be informed about predatory publishing practices and contribute to the trustworthiness of scholarly publications. In line with this, there have been several attempts to distinguish legitimate and illegitimate journals by blacklisting unethical journals (the Jeffrey Beall's list), issuing a statement on transparency and best publishing practices (the Open Access Scholarly Publishers Association's and other global organizations' draft document), and tightening the indexing criteria by the Directory of Open Access Journals. None of these measures alone turned to be sufficient. All stakeholders of science communication should be aware of multiple facets of unethical practices and publish well-checked and evidence-based articles.

    Powers, Kevin J

    2005-01-01

    A total of 326 programs are represented in the data collected. Based on the average number of full- and part-time faculty members reported per program, this survey represents more than 1500 faculty positions. Based on the forecast of retirement and career change for all faculty members, there will be a turnover of 700 to 800 positions over the next 5 to 10 years. Part-time/adjunct faculty vacancies are expected to create the greatest number of opportunities for technologists to make the transition to education, with approximately one third of current part-time/adjunct educators planning on leaving radiologic sciences education within 5 years. To encourage retention of part-time/adjunct educators, annual evaluations should be modified to recognize the important educational role these instructors play. There is a need to create enthusiasm and interest in education as a career pathway for radiologic technologists. Resources are needed that help radiologic technologists make the transition to teaching. Finally, the retention of educators must be emphasized. Program applicant trends indicate radiologic technology students are older, have prior postsecondary education experience or are making a career change. This data emphasizes the need for educators, both full time and part time, to understand the characteristics and needs of the adult learner. Adult learners bring a wealth of education, experience and life skills that create both opportunities and challenges in the classroom and clinical setting. All categories of respondents indicated that their current salaries were greater than those of program graduates in their firstjob. Of interest is that 1 in 5 (20%) of part-time/adjunct educators indicated the opposite--that program graduates earn more in their firstjob than educators earn. When asked about salaries if working full time in clinical practice, the majority of all groups indicated their salary would be about the same or would decrease. Only 20% of program

    Approximately 20% of suicide decedents have had contact with a mental health professional within 1 month prior to their death, and the majority of mental health professionals have treated suicidal individuals. Despite limited evidence-based training, mental health professionals make important clinical decisions related to suicide risk assessment and management. The current study aimed to determine the frequency of suicide risk assessment and management practices and the association between fear of suicide-related outcomes or comfort working with suicidal individuals and adequacy of suicide risk management decisions among mental health professionals. Mental health professionals completed self-report assessments of fear, comfort, and suicide risk assessment and management practices. Approximately one third of mental health professionals did not ask every patient about current or previous suicidal thoughts or behaviors. Further, comfort, but not fear, was positively associated with greater odds of conducting evidence-based suicide risk assessments at first appointments and adequacy of suicide risk management practices with patients reporting suicide ideation and a recent suicide attempt. The study utilized a cross-sectional design and self-report questionnaires. Although the majority of mental health professionals report using evidenced-based practices, there appears to be variability in utilization of evidence-based practices.

    2017-07-01

    Full Text Available Introduction: Evidence-based practice (EBP is the conscientious, explicit and judicious use of the current evidence in clinical decision making. The physiotherapy profession has expressed a commitment to the development and use of evidence. However, very little is known about the extent to which EBP is integrated in physiotherapy curricula in India. The purpose of this study was to describe integration of EBP in Indian physiotherapy programs. Methods: An observational study was conducted where a review of curricula of all Health Science Universities (HSU in India, offering an undergraduate (UG and post-graduate (PG degree program in physical therapy was conducted using a data abstraction sheet. It gathered data on inclusion of research components of EBP in the curricula, content and hours of teaching EBP, and assessment methods. Data were analyzed descriptively. Results: Curricula of fifteen HSU offering physiotherapy programs were reviewed. Contents relevant to EBP were incorporated from the 2nd yr to final year. Common courses included research methodology (84.61%, research project (69.23% and clinical management subjects (57.14%. No guidelines were given about adopting EBP in clinical practice. Didactic lectures were the mode of teaching (81.81%. Preferred method for assessing research projects was viva (44.44%. Critical appraisal was least included in the entry level education. Contents relevant to all the five steps of EBP were included in PG curricula. Conclusions: Though physiotherapy programs are introducing EBP teaching at the entry level, it lacks structured systematic approach and is fragmented. There is inadequate emphasis on clinical oriented teaching of EBP and assessment methods. Moreover, there is adequate coverage of EBP content in PG curricula.

  8. Gender and practical skill performance in science

    Science.gov (United States)

    Lock, Roger

    The performance of 18 boys and 18 girls on four problem-solving tasks set in science contexts was compared. The tasks were administered in a one-to-one testing situation and assessments were made by direct observation, questioning, and by using written records. The tasks were valid and reliable, and the samples of boys and girls were matched for ability and curriculum background. Past studies have identified gender differences in performance on science tasks; however, this study found little evidence to support these findings. Few significant differences in performance were found. No gender differences were detected in observation, reporting, or planning skills, and there was no differential performance on the use of scientific language. Girls performed less well in relation to self-reliance, and performance differences on the interpretation skill approached significance with boys' performance superior.

    Self-assessment is an important skill necessary for continued development of a health care professional from student pharmacist throughout their professional career. This paper reviews the literature on student and practitioner self-assessment and whether this skill can be improved upon. Although self-assessment appears to be a skill that can be improved, both students and professionals continue to have difficulty with accurate self-assessment. Experts' external assessment of students should remain the primary method of testing skills and knowledge until self-assessment strategies improve. While self-assessment is important to lifelong learning, external assessment is also important for practitioners' continuing professional development. PMID:20798800

    Full Text Available Background: Health sciences students are expected to have appropriate knowledge and attitudes toward medication use. However, literary evidence of such expertise among health sciences students of King Saud University is unknown. This study was completed to assess the knowledge about medicines and behavior of health science students towards safe use of medications. It also aims to assess the health knowledge, attitude and practices of the students. Methods: This cross-sectional study used a questionnaire consisting of 24 questions. This was administered by the researcher between October and December 2009 in the colleges of medicine, dentistry, pharmacy, applied medical science and nursing of the King Saud University. The survey consisted of three parts: Ten questions assessed the students’ knowledge on drug safety (Part 1. Four questions assessed student attitude toward medication consultations by the pharmacist (Part 2 and ten questions involved medication use practices and consultation with pharmacists (Part 3. A stratified sampling method was used to select participants. Results: Pharmacy students had better medication knowledge compared to other health sciences students especially regarding antihypertensive drugs, antibiotics, paracetamol and antacids (p<0.05. Pharmacy students showed a positive attitude regarding the trustworthiness of a pharmacist to give a consultation. Nearly all other health science students showed a negative attitude about dispensing and consultation concerning nutritional supplements by a pharmacist. All health sciences students had a similar perception toward medication use and practice. Conclusion Pharmacy students had better knowledge about medication practice compared to other health sciences students. All other health sciences students lacked the appropriate attitude and practice related to the safe use of medications.

    the defined boundaries. This ensures the accuracy of the classification. Third, when item threshold parameters vary a bit, the scoring rubrics and the items need to be reviewed to make the threshold parameters similar across items. This is because one important design criterion of the learning progression-based items is that ideally, a student should be at the same level across items, which means that the item threshold parameters (d1, d 2 and d3) should be similar across items. To design a learning progression-based science assessment, we need to understand whether the assessment measures a single construct or several constructs and how items are associated with the constructs being measured. Results from dimension analyses indicate that items of different carbon transforming processes measure different aspects of the carbon cycle construct. However, items of different practices assess the same construct. In general, there are high correlations among different processes or practices. It is not clear whether the strong correlations are due to the inherent links among these process/practice dimensions or due to the fact that the student sample does not show much variation in these process/practice dimensions. Future data are needed to examine the dimensionalities in terms of process/practice in detail. Finally, based on item characteristics analysis, recommendations are made to write more discriminative CR items and better OMC, MTF options. Item writers can follow these recommendations to write better learning progression-based items.

    Science teachers are expected to teach in innovative ways that are different from their long experience as students. Professional development programs are planned to help teachers' development, yet, there is little knowledge of the long-term effects of professional development programs (PDPs), and especially on actual practice. The purpose of this study is to gain a long-term perspective of the ways in which the process and outcomes of a reform-oriented, extended PDP are expressed in science teachers' practice. Data sources included interviews and documents. The study presents four case studies of the practices of junior high school science teachers (grades 7-9) in Israel, with respect to a past PDP in which they took part a decade ago. The cases are presented in pairs of a leader and a follower. Each case details the teacher's work context, sustained implementation, coherence of tools and approaches, and adaptations. All four teachers shared the view that scientific skills are important to their students as learners in a changing world. All four teachers adopted one or two major approaches, which were the PDP's main focus. In addition, the two leaders adopted two more approaches. The teachers were still using many strategies associated with the major foci of the PDP. The level of enactment and modifications of the strategies varied. Usability of innovations is discussed in relation to the teachers' context. We suggest that science teachers' professional development include the ability to adapt the innovation to their teaching context in order to sustain the changes for a long period of time.

    Despite the objectivity of science, the local work environment affects the daily activities of scientists. Differences in cultural perception can affect female scientists in the workplace directly. The pressure currently exerted on researchers, on the other hand, is altering how science is practiced and seems to affect women and men differently. In this paper we summarize the discussions that took place on this topic in Workshop V of the 5th IUPAP International Conference on Women in Physics. We present some of the results of the 2010 Global Survey of Physicists analyzed by region and data from France and Taiwan. We also include the recommendations that were formulated at the end of the workshop.

    Since the launch of the NASA Terra and Aqua satellites in December 1999 and May 2002, respectively, atmosphere and land data acquired by the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor on-board these satellites have been reprocessed five times at the MODAPS (MODIS Adaptive Processing System) located at NASA GSFC. The global land and atmosphere products use science algorithms developed by the NASA MODIS science team investigators. MODAPS completed Collection 6 reprocessing of MODIS Atmosphere science data products in April 2015 and is currently generating the Collection 6 products using the latest version of the science algorithms. This reprocessing has generated one of the longest time series of consistent data records for understanding cloud, aerosol, and other constituents in the earth's atmosphere. It is important to carefully evaluate and assess the quality of this data and remove any artifacts to maintain a useful climate data record. Quality Assessment (QA) is an integral part of the processing chain at MODAPS. This presentation will describe the QA approaches and tools adopted by the MODIS Land/Atmosphere Operational Product Evaluation (LDOPE) team to assess the quality of MODIS operational Atmospheric products produced at MODAPS. Some of the tools include global high resolution images, time series analysis and statistical QA metrics. The new high resolution global browse images with pan and zoom have provided the ability to perform QA of products in real time through synoptic QA on the web. This global browse generation has been useful in identifying production error, data loss, and data quality issues from calibration error, geolocation error and algorithm performance. A time series analysis for various science datasets in the Level-3 monthly product was recently developed for assessing any long term drifts in the data arising from instrument errors or other artifacts. This presentation will describe and discuss some test cases from the

  18. Evaluating the impact of geologic heritage on Earth science literacy: Adapting best practices from pedagogy and interpretation (Invited)

    How might we authentically and practically evaluate the effects of a geologic heritage place or program on public Earth science literacy? This pedagogical form of evaluation is distinct from the evaluation of a place for its geological importance, heritage value, economic or cultural impact, and so on. Best evaluation practices from the realms of formal education, informal education, and interpretation start with a coherent set of evaluable learning outcomes, ideally recapitulated in one or more 'big ideas' that capture the essential attributes of the place or program. Learning outcomes may be classified as cognitive, affective, or psychomotor. Cognitive learning outcomes in a geoheritage context are the Earth-science concepts a visitor or student would be expected to uncover through on-site or virtual exploration of the stratigraphy, structure, landforms, and processes in a place. The Earth Science Literacy Principles (ESLP), and similar literacy documents relating to atmosphere, oceans, and climate; offer a template for mapping localized concepts onto more global ones. Quantitative instruments to evaluate understanding of the ESLP are in development, and the ESLP also map directly onto measures used in formal educational assessment, notably the Next Generation Science Standards in the USA. Nongeological place meanings (a component of sense of place) may suggest other cognitive outcomes. Affective learning outcomes for visitors and students in geoheritage sites are less readily defined, but may include place attachment (also a component of sense of place), attitudes, and interest. Multiple quantitative and qualitative methods of evaluating these outcomes exist. Psychomotor learning outcomes are even muddier, but accessibility (defined by statutes) offers a potential starting point. In practice, evaluation may be conducted synchronously or asynchronously with visitors' or students' interaction with the geoheritage place or program. Evaluation programs are typically

  19. Using cognitive referents in making sense of teaching: A chemistry teacher's struggle to change assessment practices

    Science.gov (United States)

    Briscoe, Carol

    This qualitative case study focused on the role of cognitive referents in the sense-making process of one teacher as he attempted to change his classroom science assessment. The interpretations identify cultural myths, conceptual metonymys, as well as personally constructed beliefs as referents that constrained change. The teacher's cognitive struggle to make sense of assessment and his role as assessor are linked to conflicting referents he used in varying contexts including day-to-day assessment and summative assessment settings. The results of the study suggest that cognitive referents are important influences in driving how a teacher thinks about assessment and may constrain an individual teacher's implementation of innovative practices. Accordingly, identification of referents such as myths, their associated beliefs, and metonymic conceptual models that teachers use to make sense of their actions is an important first step in developing an understanding of constraints to educational change.

  20. The Science Shop for Physics: an interface between practical problems in society and physical knowledge

    van den Berg, G. P.

    1998-03-01

    Since some 20 years most Dutch universities have one or more science shops. Central shops handle research questions for all disciplines. Specialized shops are part of a department of chemistry or medicine, history, social science, etc. The shops have evolved rather differently, but their main mission still is to help social groups that lack money and have no easy access to scientific knowledge, e.g. neighbourhood, environmental, third world or patient groups. Most also help non-commercial organizations such as schools, trade unions or local authorities. Low-cost help can be provided because students do the work as part of their training, mainly in student projects (literature search, practical work, graduation, etc.). A total staff of 80, helped by 600 students, 250 voluntary and 50 paid researchers, handle 1500 questions resulting in 300 reports (estimated figures 1995). Science shops for physics (`Physics Shop', PS) have to deal with practical problems, generally involving classical physics. Major topics are noise, vibration, radiation, indoor climate and energy: most of the work lies in estimating/measuring relevant parameters, assessing impact, seeking solutions. The 3 Dutch PS's have developed in different directions. One is run entirely by students and deals with small, concrete problems. The second PS is managed by a co-ordinator who mediates between client groups and physics staff members who assist students in small and larger projects. The third has a lot of in-house expertise, and the shop staff is in direct contact with client groups as well as students who work in the PS itself. In questions submitted to the PS it is not always immediately clear what to do or how to do it because of the non-scientific phrasing of the problems and problems include non-physical (e.g. technical, health or legal) aspects. Also, difficulties in solving the problems are typically not in the underlying physics, but in the lack of accurate data and of control of the complex

    Using peer learning strategies, seven experienced PBRNs working in collaborative teams articulated procedures for PBRN Research Good Practices (PRGPs). The PRGPs is a PBRN-specific resource to facilitate PBRN management and staff training, to promote adherence to study protocols, and to increase validity and generalizability of study findings. This paper describes the team science processes which culminated in the PRGPs. Skilled facilitators used team science strategies and methods from the Technology of Participation (ToP®), and the Consensus Workshop Method to support teams to codify diverse research expertise in practice-based research. The participatory nature of "sense-making" moved through identifiable stages. Lessons learned include (1) team input into the scope of the final outcome proved vital to project relevance; (2) PBRNs with diverse domains of research expertise contributed broad knowledge on each topic; and (3) ToP® structured facilitation techniques were critical for establishing trust and clarifying the "sense-making" process. © 2015 Wiley Periodicals, Inc.

    2016-02-01

    The integration of mathematics and science teaching and learning facilitates student learning, engagement, motivation, problem-solving, criticality and real-life application. However, the actual implementation of an integrative approach to the teaching and learning of both subjects at classroom level, with in-service teachers working collaboratively, at second-level education, is under-researched due to the complexities of school-based research. This study reports on a year-long case study on the implementation of an integrated unit of learning on distance, speed and time, within three second-level schools in Ireland. This study employed a qualitative approach and examined the key aspects of practice that impact on the integration of mathematics and science teaching and learning. We argue that teacher perspective, teacher knowledge of the 'other subject' and of technological pedagogical content knowledge (TPACK), and teacher collaboration and support all impact on the implementation of an integrative approach to mathematics and science education.

    2014-02-01

    Despite the wide agreement among educators that classroom learning and teaching processes can gain much from student and teacher questions, their potential is not fully utilized. Adopting the view that reporting both teachers' (of varying age groups) views and actual classroom practices is necessary for obtaining a more complete view of the phenomena at hand, the present study closely examines both cognitive and affective domains of: (a) teachers' views (via interviews) concerning: (1) importance and roles of teacher and student questions, (2) teacher responses, and (3) planning and teacher training; and (b) teachers' actual practices (via classroom observations) concerning: (1) number and (2) level of teacher and student questions, as well as (3) teachers' responses to questions. The data were collected from 3 elementary, 3 middle, and 3 high school science teachers and their respective classroom students. The findings lay out a wide view of classroom questioning and teachers' responses, and relate what actually occurs in classes to teachers' stated views. Some of the study's main conclusions are that a gap exists between how science researchers and teachers view the role of teacher questions: the former highlight the cognitive domain, while the latter emphasize the affective domain.

  5. Health Technology Assessmentscience or art?

    Hofmann, Bjørn

    2013-01-01

    The founding disciplines of HTA are clearly scientific, and have been firmly based among the natural sciences. However, common definitions of HTA indicate that HTA is something more than the “pure application of science”. This article investigates whether this “something” also makes HTA an art. The question of whether HTA is a science or an art is pursued in two specific and historically rich directions. The first is whether HTA is an art in the same way that medicine is described as an art. It has been argued extensively that medicine is based on two different and partly incompatible cultures, i.e., the natural sciences and humanities. Medicine is based on disciplines within the natural sciences, while its value judgments have been placed in the humanities camp. This dichotomy is present in HTA as well, and the first part of the investigation illustrates how HTA is an art in terms of its inherent and constitutive value-judgments. The second part of the science/art-scrutiny leads us to the ancient (Hippocratic) concept of art, téchne, where we find an etymological and a conceptual link between HTA and art. It demonstrates HTA is not an arbitrary process, even though it involves value judgments and relates complex decision making processes. As an art (téchne) HTA has a specific subject matter, requires inquiry and mastery of general rational principles, and is oriented to a specific end. In conclusion, the science-or-art-question makes sense in two specific perspectives, illustrating that HTA is a science based art. This has implications for the practice of HTA, for its education, and for the status of its results. PMID:23935761

    2017-06-01

    Given reform recommendations emphasizing scientific inquiry and empirical evidence pointing to the difficulties beginning teachers face in enacting inquiry-based science, this study explores a well-started beginning elementary teacher's (Sofia) beliefs about inquiry-based science and related instructional practices. In order to explore Sofia's beliefs and instructional practices, several kinds of data were collected in a period of 9 months: a self-portrait and an accompanying narrative, a personal philosophy assignment, three interviews, three journal entries, ten lesson plans, and ten videotaped classroom observations. The analysis of these data showed that Sofia's beliefs and instructional practices were reform-minded. She articulated contemporary beliefs about scientific inquiry and how children learn science and was able to translate these beliefs into practice. Central to Sofia's beliefs about science teaching were scientific inquiry and engaging students in investigations with authentic data, with a prevalent emphasis on the role of evidence in the construction of scientific claims. These findings are important to research aiming at supporting teachers, especially beginning ones, to embrace reform recommendations.

    This study addressed a prevalence of low achievement in science courses in an urban school district in Georgia. National leaders and educators have identified the improvement of science proficiency as critical to the future of American industry. The purpose of this study was to examine parent involvement in this school district and its contribution to the academic achievement of successful science students. Social capital theory guided this study by suggesting that students achieve best when investments are made into their academic and social development. A collective case study qualitative research design was used to interview 9 parent participants at 2 elementary schools whose children scored in the exceeds category on the Science CRCT. The research questions focused on what these parents did at home to support their children's academic achievement. Data were collected using a semi-structured interview protocol and analyzed through the categorical aggregation of transcribed interviews. Key findings revealed that the parents invested time and resources in 3 practices: communicating high expectations, supporting and developing key skills, and communicating with teachers. These findings contribute to social change at both the local and community level by creating a starting point for teachers, principals, and district leaders to reexamine the value of parent input in the educational process, and by providing data to support the revision of current parent involvement policies. Possibilities for further study building upon the findings of this study may focus on student perceptions of their parents' parenting as it relates to their science achievement.

Analysis of qualitative data revealed key findings: (1) the school's Habits of Mind, authentic scientific inquiry, self-regulated learning triggers and strategies, and teacher feedback practices driven by an ethic of care supported students' science learning and portfolio assessment; and (2) the cyclical and extensive portfolio processes of writing, revision, and submission well prepared alumni for college science laboratory work and coursework, to a certain extent, but not for the traditional assessments administered in college science courses. Analysis of quantitative data revealed that, if based solely on the City University of New York's Regents score criteria for college readiness, the majority of students from these two graduating classes studied would not have been considered college ready even though all participants, including interviewed alumni, believed the school prepared them for college. The majority of these students, however, were transitioning to college readiness based on their Regents-level science and mathematics coursework. Findings of this study have implications for science assessment, professional development in science, education policy reform, and high school partnerships with CBOs and postsecondary institutions as they pertain to college and college science readiness for students of color in urban portfolio community high schools.

Sleep hygiene practices are one of the important variables that affect sleep quality. The objective of this study was to assess association between sleep hygiene practices and sleep quality of medical students in Qazvin University of Medical Sciences. Methods: In this descriptive-correlational study, a total of 285 medical students completed a self-administered questionnaire. Demographic data, sleep-wake schedule in weekday and weekend, and sleep duration were collected. Students' sleep quality was assessed by Pittsburg Sleep Quality Index (PSQI. Data were analyzed by SPSS Ver 13. Results: Overall, 164 (57.5 of students had poor sleep quality. Mean global PSQI score and average score of four subscales were significantly higher in male than female. Regression analysis showed that male students (β=-0.85, P<0.05, students at senior level (β=-0.81, P<0.05, married students (β=-0.45, P<0.05, and those with improper sleep hygiene practices slept worse. Conclusion: The findings of this study showed that the prevalence of poor sleep quality in medical students is high. Improper sleep hygiene behaviors might be a reason for poor quality of sleep in medical students.

    2018-04-01

    Learning basic science forms an essential foundation for oral health therapy and dentistry, but frequently students perceive it as difficult, dry, and disconnected from clinical practice. This perception is encouraged by assessment methods that reward fact memorization, such as objective examinations. This study evaluated use of a learner-centered assessment portfolio designed to increase student engagement with basic science in an oral health therapy program at the University of Sydney, Australia. The aim of this qualitative study based on focus groups was to investigate students' engagement with basic science courses following introduction of the portfolio. Three assessments were conducted in three subsequent semesters: one based on students' interest in everyday phenomena (one student, for example, explored why she had red hair); the second focussed on scientific evidence and understanding of systemic diseases; and the third explored relations between oral and general health. Students were encouraged to begin with issues from their personal experience or patient care, to focus on what they were curious about, and to ask questions they really cared about. Each student prepared a written report and gave an oral presentation to the entire cohort. After the portfolios were completed, the authors held focus groups with two cohorts of students (N=21) in 2016 and analyzed the results using Zepke's framework for student engagement research. The results showed that the students successfully interweaved personal experience into their studies and that it provided significant motivation for learning. The students described their learning in terms of connection to themselves, their peer community, and their profession. Many additional benefits were identified, from increased student engagement in all courses to appreciation of the relevance of basic science. The findings should encourage dental and allied dental educators to reconsider the effects of assessments and seek

    Full Text Available As citizen science inherently relies upon unpaid contributors, providing a positive experience for participants is critical. This case study describes the use of social media to support participants of the New Zealand Garden Bird Survey and examines the group’s interactions in its first year through the lens of a community of practice. Communities of practice can provide forums for learning, which is an important outcome of participation by environmental volunteers. Social media can provide the setting for an online community of practice that can support dispersed groups of volunteers and requires little daily input from administrators. While the NZ Garden Bird Survey runs for only nine days annually in June–July, this Facebook group continued to be active and attract new members throughout the year. In the first year of its existence, the group grew to 1,275 members who generated nearly 75,000 interactions (posts, comments, likes, and shares. The group was used to share enthusiasm, ideas, and knowledge about New Zealand’s garden birds. A wide range of birding expertise, from novice to expert, was displayed. The group’s interactions include shared interests, contributed stories, and collective learning. This paper documents our experiences setting up and administering this group and provides advice for citizen science programs that want to use social media to support a community of practice.

    Full Text Available In the current changing environment of work, the process of competence assessment is increasingly relevant as workers gain knowledge and practical skills through fulfilling different and new working tasks and through self-education. In this context, innovative tools for competence assessment and validation are very useful for encouraging movement of individuals between jobs and from unemployment or inactivity to employment and for increasing the capacity of companies to respond and adapt to changing and challenging environments. This article presents an overview of best practices for competence assessment and validation in order to identify and select methods that have been effective in various European countries including Romania. The article concludes with a set of „learned lessons” and short recommendations in order to improve the framework of competence assessment in Romanian context. Our findings are useful for the new human resources management that aims toward efficiently usage of the workforce, inside companies and in a global labour market, encouraging flexibility and adaptability.

    Jefferson, A.; McKinnon, M.

    2016-12-01

    Doing science in public has incalculable benefits for professional networking, science advocacy, and public outreach, but it also carries significant risks. Online harassment related to social media use can pose significant emotional hardship, negatively impact professional standing, and even threaten physical welfare. Women, people of color, and other underrepresented people in science are disproportionately targeted for anonymous online harassment. We analyzed our experiences with online harassment, and tactics for managing this harassment. While anecdotal, our experiences cover scientists with differing identities and fields, demonstrating that while the details change the overarching patterns remain the same. Fear of becoming a target poses a significant barrier to engaging in public discourse about science. But it is possible to mitigate this risk. Successful strategies for social media to promote science while staying safe are slowly creating a body of emerging best practices. These tactics include proactively restricting access to personal information, developing strategies for identifying and responding to deliberate antagonists (trolls), and choosing when and how to participate in volatile topics. They also require full-community engagement from creating support networks, partnering with allies to manage sudden floods of hostility, and educating on security practices for protecting colleagues' potentially sensitive personal information. It is our hope that frank and open discussion of the realistic threat passed by harassment and strategies for mitigating that threat will jump start a culture of online safety amongst geoscientists, and encourage our most vulnerable and underrepresented scientists to participate in the public sphere.

    Full Text Available In this research, a case study, we adopted ethnography as logic of inquiry to learn about teaching for diverse groups in middle school science classrooms. Multiple data sources were used: participant observation, video and audio records, field notes and semi-structured interviews. We analyzed interviews with two teachers, as well as classroom episodes to construct, through contrast, a characterization of two types of practice involving diversity in the classroom. The first teacher show concerns with introducing students in school culture. She tried to “translate” terms that students do not understand, explaining their meanings. In this process, teaching subject matter knowledge (SMK is a secondary goal. The other teacher emphasized SMK, trying to establish connections between science content and students’ everyday life experiences. Both teachers do not acknowledge significant influences in science learning related to gender, social class, and ethnicity.

    2015-12-01

    An important goal of science education is to support development of citizens to participate in public debate and make informed decisions relevant to their lives and their worlds. The NGSS (Next Generation Science Standards) suggest engaging students in science classrooms in argumentation as a practice to help enhance the quality of evidence based decision making. In this multi-case study, we explored the use of written argumentation in eight secondary school science classrooms during a lesson on the relationship between ocean temperature and its CO2 holding capacity. All teachers of these classrooms were trained during a day long NSF funded Climate Literacy Workshop on the basic concepts of climate science, scientific practices and implementation of an activity called "It's a Gassy World". The data of the current study involved students' written arguments, teachers' written reflections on the implementation of the activity as well as field notes from the Climate Literacy Workshop. A qualitative discourse analysis of the data was used to find common themes around affordances and challenges of argument as a connective discourse for scientific practices to teach climate change. The findings show that participating in written argumentation process encouraged students to discuss their experimental design and use data interpretation for their evidences. However, the results also indicated the following challenges: a) teachers themselves need support in connecting their evidence to their claims, b) arguing a socioscientific issue creates a sensitive environment c) conceptual quality of an argument needs to be strengthen through background in courses other than science, and d) graphing skills (or lack of) can interfere with constructing scientifically accurate claims. This study has implications in effectively teaching climate change through argumentation, and thus creating opportunities for practicing authentic climate science research in K-12 classrooms.

  8. Best Practices for Implementing Inquiry-Based Science Instruction for English Language Learners

    Williams, Erica

    This applied dissertation was designed to provide better access to current information to link literacy and science. Students frequently used literacy skills to gather information and communicate understanding of scientific concepts to others. Science became applicable through the tools associated with literacy. There was a need for instruction that integrated language development with science content. This research focused on revealing the instructional trends of English language learners science teachers in the United Arab Emirates. The researcher introduced the questionnaire surveys in the form of a professional development session. The participants were asked to complete the questionnaire concurrently with the descriptive presentation of each component of the sheltered instruction observation protocol (SIOP) model. Completing the SIOP Checklist Survey provided data on the type of constructivist strategies (best practices) teachers were utilizing and to what degree of fidelity the strategies were being implemented. Teachers were encouraged to continue to use these services for curriculum enrichment and as an additional source for future lesson plans. An analysis of the data revealed authentic learning as the most common best practice used with the most fidelity by teachers. The demographic subgroup, teaching location, was the only subgroup to show statistical evidence of an association between teaching location and the use of problem-based learning techniques in the classroom. Among factors that influenced the degree of teacher fidelity, teachers' expectation for student achievement had a moderate degree of association between the use of scaffolding techniques and co-operative learning.

  9. Case study of science teaching in an elementary school: Characteristics of an exemplary science teacher

    Kao, Huey-Lien

    Improving the quality of science teaching is one of the greatest concerns in recent science education reform efforts. Many science educators suggest that case studies of exemplary science teachers may provide guidance for these reform efforts. For this reason, the characteristics of exemplary science teaching practices have been identified in recent years. However, the literature lacks research exploring exemplary teacher beliefs about the nature of science and science pedagogy, the relationships between their beliefs and practices, or how outstanding teachers overcome difficulties in order to facilitate their students' science learning. In this study, Sam-Yu, an identified exemplary science teacher who teaches in an elementary school in Pintung, Taiwan, was the subject. An interpretative research design (Erickson, 1986) based on principles of naturalistic inquiry (Lincoln & Guba, 1985) was used. Both qualitative and quantitative methods were employed in this case study. The qualitative method involved conducting interviews with the teacher and students, observing classroom activities and analyzing the structure of the learning materials. The quantitative methods involved using the Learning Climate Inventory (LCI) (Lin, 1997) instrument to assess the learning environment of the exemplary science classroom. This study found that Sam-Yu had a blend of views on the nature of science and a varied knowledge about science pedagogy. Personal preferences, past experiences, and the national science curriculum all played important roles in the development and refinement of Sam-Yu's beliefs about science and pedagogy. Regarding his teaching practices, Sam-Yu provided the best learning experiences, as evidenced in both classroom observations and the survey results, for his students by using a variety of strategies. In addition, his classroom behaviors were highly associated with his beliefs about science and pedagogy. However, due to school-based and socio-cultural constraints

    Assessment skills are an important component of assessment practice, without adequate assessment skills it is unlikely that teacher assessment practices will produce desired student learning outcomes. This study was conducted to reveal self-perceived assessment skills of prospective physics teachers by using quantitative descriptive analysis, and involving 92 prospective physics teachers who were experiencing teaching practice in junior high school and final project related to assessment. Data was collected by using Self-Perceived Assessment Science Skills Questionnaire consisted of 29 items related seven assessment competencies was developed and used in the study. Internal consistency reliability coefficient for the total scale scores was 0.87 as measured by Cronbach’s alpha. Determination of self-perceived assessment science skills detected from prospective physics teachers was carried out in descriptive statistics, in the form of respondent average values. Research findings show that self-perceived assessment skills of prospective physics teachers was categorized as transition.

  11. High school students presenting science: An interactional sociolinguistic analysis

    Bleicher, Robert

    Presenting science is an authentic activity of practicing scientists. Thus, effective communication of science is an important skill to nurture in high school students who are learning science. This study examines strategies employed by high school students as they make science presentations; it assesses students' conceptual understandings of particular science topics through their presentations and investigates gender differences. Data are derived from science presentation given by eight high school students, three females and five males who attended a summer science program. Data sources included videotaped presentations, ethnographic fieldnotes, interviews with presenters and members of the audience, and presenter notes and overheads. Presentations were transcribed and submitted to discourse analysis from an interactional sociolinguistic perspective. This article focuses on the methodology employed and how it helps inform the above research questions. The author argues that use of this methodology leads to findings that inform important social-communicative issues in the learning of science. Practical advice for teaching students to present science, implications for use of presentations to assess conceptual learning, and indications of some possible gender differences are discussed.Received: 14 April 1993; Revised: 15 February 1994;

  12. Designing systematic conservation assessments that promote effective implementation: best practice from South Africa.

    Systematic conservation assessment and conservation planning are two distinct fields of conservation science often confused as one and the same. Systematic conservation assessment is the technical, often computer-based, identification of priority areas for conservation. Conservation planning is composed of a systematic conservation assessment coupled with processes for development of an implementation strategy and stakeholder collaboration. The peer-reviewed conservation biology literature abounds with studies analyzing the performance of assessments (e.g., area-selection techniques). This information alone, however can never deliver effective conservation action; it informs conservation planning. Examples of how to translate systematic assessment outputs into knowledge and then use them for "doing" conservation are rare. South Africa has received generous international and domestic funding for regional conservation planning since the mid-1990s. We reviewed eight South African conservation planning processes and identified key ingredients of best practice for undertaking systematic conservation assessments in a way that facilitates implementing conservation action. These key ingredients include the design of conservation planning processes, skills for conservation assessment teams, collaboration with stakeholders, and interpretation and mainstreaming of products (e.g., maps) for stakeholders. Social learning institutions are critical to the successful operationalization of assessments within broader conservation planning processes and should include not only conservation planners but also diverse interest groups, including rural landowners, politicians, and government employees.

    2015-12-01

    Full Text Available With a quadrupling of forensic psychiatric patients in Denmark over the past 20 years, focus on violence risk assessment practices across the country has increased. However, information is lacking regarding Danish risk assessment practice across professional disciplines and clinical settings; little is known about how violence risk assessments are conducted, which instruments are used for what purposes, and how mental health professionals rate their utility and costs. As part of a global survey exploring the application of violence risk assessment across 44 countries, the current study investigated Danish practice across several professional disciplines and settings in which forensic and high-risk mental health patients are assessed and treated. In total, 125 mental health professionals across the country completed the survey. The five instruments that respondents reported most commonly using for risk assessment, risk management planning and risk monitoring were Broset, HCR-20, the START, the PCL-R, and the PCL:SV. Whereas the HCR-20 was rated highest in usefulness for risk assessment, the START was rated most useful for risk management and risk monitoring. No significant differences in utility were observed across professional groups. Unstructured clinical judgments were reported to be faster but more expensive to conduct than using a risk assessment instrument. Implications for clinical practice are discussed.

    Jita, Loyiso Currell

    1999-11-01

    This study investigated the construction of teaching practices that are aimed at including all students in learning the key ideas of science and helping them to develop a voice for participating in the discourses in and outside of the science classroom. Such practices define what in this study is referred to as transformative practice. The study tells the stories of three Black secondary school teachers in South Africa who have worked to construct a transformative practice in their biology and physical science classrooms. Using a life history perspective, the study explored the relationships between teachers' identities and the changes in their classroom practices. Data were collected mainly through periodic interviews with the teachers and observations of their teaching practices over a period of 18 months. An important finding of the study was that the classroom practices of all three teachers were defined by three similar themes of: (1) "covering the content" and preparing their students to succeed in the national examinations, (2) developing deep conceptual understandings of the subject matter, and (3) including all students in their teaching by constructing what other researchers have called a "culturally-relevant" pedagogy. This finding was consistent despite the observed variations of context and personal histories. A major finding of this study on the question of the relationship between identity and teaching practice was that despite the importance of context, subject matter, material and social resources, another category of resources---the "resources of biography"---proved to be crucial for each of the teachers in crafting a transformative pedagogy. These "resources of biography" included such things as the teachers' own experiences of marginalization, the experiences of growing up or living in a particular culture, and the experiences of participating in certain kinds of social, political, religious or professional activities. The study suggests that it

  17. Learning the 'grammar of science': The influence of a physical science content course on teachers' understanding of the nature of science

    Science.gov (United States)

    Hanuscin, Deborah L.

    This research examined the development of practicing K--8 teachers' views of the nature of science (NOS) within a physical science content course. Reforms in science education have called for the teaching of science as inquiry. In order to achieve the vision of the reforms, teachers must understand science, both a body of knowledge and as a process, but also the very nature of science itself-or the values and assumptions inherent in the construction of scientific knowledge. NOS has been deemed a critical component of scientific literacy, with implications for making informed decisions about scientific claims. Research has indicated that despite the emphasis of reforms, teachers generally do not possess accurate views of NOS. Recent work in science education has led to the recommendation that efforts undertaken within teacher education programs to improve teachers' understanding of NOS can be enhanced through relevant coursework in other academic areas, including the sciences. The purpose of this dissertation was to provide an empirical basis for this recommendation, by examining the development of teachers' views of NOS within a physical science content course. To this end, the researcher employed qualitative methodology including participant observation, interview, document analysis, and questionnaire to assess teacher participants' views of the nature of science and the impact of their experience in the content course on these views. As a result of this research, implications for both the course design and science teacher education have been described. In addition, various aspects of the community of practice that characterizes the classroom that inhibit the development of understandings about the nature of science are identified. It is argued that instruction in NOS should be approached from the perspective that builds bridges between the communities of practice of learners and of scientists.

    Babaie, Mahya

    The purpose of this quantitative, descriptive, single group, pretest posttest design study was to explore the influence of a Virtual Science Laboratory (VSL) on middle school students' cognitive knowledge, skill development, and attitudes toward science. This study involved 2 eighth grade Physical Science classrooms at a large urban charter middle school located in Southern California. The Buoyancy and Density Test (BDT), a computer generated test, assessed students' scientific knowledge in areas of Buoyancy and Density. The Attitude Toward Science Inventory (ATSI), a multidimensional survey assessment, measured students' attitudes toward science in the areas of value of science in society, motivation in science, enjoyment of science, self-concept regarding science, and anxiety toward science. A Virtual Laboratory Packet (VLP), generated by the researcher, captured students' mathematical and scientific skills. Data collection was conducted over a period of five days. BDT and ATSI assessments were administered twice: once before the Buoyancy and Density VSL to serve as baseline data (pre) and also after the VSL (post). The findings of this study revealed that students' cognitive knowledge and attitudes toward science were positively changed as expected, however, the results from paired sample t-tests found no statistical significance. Analyses indicated that VSLs were effective in supporting students' scientific knowledge and attitude toward science. The attitudes most changed were value of science in society and enjoyment of science with mean differences of 1.71 and 0.88, respectively. Researchers and educational practitioners are urged to further examine VSLs, covering a variety of topics, with more middle school students to assess their learning outcomes. Additionally, it is recommended that publishers in charge of designing the VSLs communicate with science instructors and research practitioners to further improve the design and analytic components of these

    In many parts of the world, newly hired science teachers' practices are developing in a complex policy environment. However, little is known about how newly hired science teachers' practices are enacted throughout a cycle of instruction and how these practices can be influenced by macro-, meso-, and micro-policies. Knowing how policies impact practice can result in better policies or better support for certain policies in order to enhance the instruction of newly hired teachers. This comparative study investigated how 12 newly hired science teachers at sites in South Africa (SA) and the United States (US) progressed through an instructional cycle of planning, teaching, and reflection. The qualitative data were analysed through beginning teacher competency frameworks, the cycle of instruction, and institutional theory. Data analysis revealed prevailing areas of practice and connections to levels of policy within the instructional cycle phases. There were some differences between the SA and US teachers and among first-, second-, and third-year teachers. More importantly, this study indicates that newly hired teachers are susceptible to micro-policies and are progressively developing their practice. It also shows the importance of meso-level connectors. It suggests that teacher educators and policy makers must consider how to prepare and support newly hired science teachers to achieve the shared global visions of science teaching.

    2012-10-01

    The performance of English language learners (ELLs) has been a concern given the rapidly changing demographics in US K-12 education. This study aimed to examine whether students' English language status has an impact on their inquiry science performance. Differential item functioning (DIF) analysis was conducted with regard to ELL status on an inquiry-based science assessment, using a multifaceted Rasch DIF model. A total of 1,396 seventh- and eighth-grade students took the science test, including 313 ELL students. The results showed that, overall, non-ELLs significantly outperformed ELLs. Of the four items that showed DIF, three favored non-ELLs while one favored ELLs. The item that favored ELLs provided a graphic representation of a science concept within a family context. There is some evidence that constructed-response items may help ELLs articulate scientific reasoning using their own words. Assessment developers and teachers should pay attention to the possible interaction between linguistic challenges and science content when designing assessment for and providing instruction to ELLs.

  5. Enabling Wide-Scale Computer Science Education through Improved Automated Assessment Tools

    Science.gov (United States)

    Boe, Bryce A.

    There is a proliferating demand for newly trained computer scientists as the number of computer science related jobs continues to increase. University programs will only be able to train enough new computer scientists to meet this demand when two things happen: when there are more primary and secondary school students interested in computer science, and when university departments have the resources to handle the resulting increase in enrollment. To meet these goals, significant effort is being made to both incorporate computational thinking into existing primary school education, and to support larger university computer science class sizes. We contribute to this effort through the creation and use of improved automated assessment tools. To enable wide-scale computer science education we do two things. First, we create a framework called Hairball to support the static analysis of Scratch programs targeted for fourth, fifth, and sixth grade students. Scratch is a popular building-block language utilized to pique interest in and teach the basics of computer science. We observe that Hairball allows for rapid curriculum alterations and thus contributes to wide-scale deployment of computer science curriculum. Second, we create a real-time feedback and assessment system utilized in university computer science classes to provide better feedback to students while reducing assessment time. Insights from our analysis of student submission data show that modifications to the system configuration support the way students learn and progress through course material, making it possible for instructors to tailor assignments to optimize learning in growing computer science classes.

  6. Views of nature of science questionnaire: Toward valid and meaningful assessment of learners' conceptions of nature of science

    2002-08-01

    Helping students develop informed views of nature of science (NOS) has been and continues to be a central goal for kindergarten through Grade 12 (K-12) science education. Since the early 1960s, major efforts have been undertaken to enhance K-12 students and science teachers' NOS views. However, the crucial component of assessing learners' NOS views remains an issue in research on NOS. This article aims to (a) trace the development of a new open-ended instrument, the Views of Nature of Science Questionnaire (VNOS), which in conjunction with individual interviews aims to provide meaningful assessments of learners' NOS views; (b) outline the NOS framework that underlies the development of the VNOS; (c) present evidence regarding the validity of the VNOS; (d) elucidate the use of the VNOS and associated interviews, and the range of NOS aspects that it aims to assess; and (e) discuss the usefulness of rich descriptive NOS profiles that the VNOS provides in research related to teaching and learning about NOS. The VNOS comes in response to some calls within the science education community to go back to developing standardized forced-choice paper and pencil NOS assessment instruments designed for mass administrations to large samples. We believe that these calls ignore much of what was learned from research on teaching and learning about NOS over the past 30 years. The present state of this line of research necessitates a focus on individual classroom interventions aimed at enhancing learners' NOS views, rather than on mass assessments aimed at describing or evaluating students' beliefs.

    2017-01-01

    School nurses are afforded minimal resources related to assessing pain in students with intellectual disability (ID) and have called for continuing education. The purpose of this study was to measure the effectiveness of an education program regarding best practices for assessing pain in students with ID. Educational sessions were presented to 248 school nurses. Pre-, post-, and follow-up surveys measured (1) difficulty school nurses face when assessing pain, (2) knowledge and use of pain assessment methods, and (3) intent to change and actual changes to professional practices. Participants experienced less difficulty assessing pain following the educational program. Almost all participants intended to change pain assessment practices, but large caseloads limited new practice adoption. Policy makers must consider population size and acuity when determining school nurse staffing. Trainings and other resources should be made available to school nurses in order to make pain assessments for students with ID more thorough and efficient.

  11. Teaching Scientists to Communicate: Evidence-based assessment for undergraduate science education

    Mercer-Mapstone, Lucy; Kuchel, Louise

    2015-07-01

    Communication skills are one of five nationally recognised learning outcomes for an Australian Bachelor of Science (BSc) degree. Previous evidence indicates that communication skills taught in Australian undergraduate science degrees are not developed sufficiently to meet the requirements of the modern-day workplace-a problem faced in the UK and USA also. Curriculum development in this area, however, hinges on first evaluating how communication skills are taught currently as a base from which to make effective changes. This study aimed to quantify the current standard of communication education within BSc degrees at Australian research-intensive universities. A detailed evidential baseline for not only what but also how communication skills are being taught was established. We quantified which communication skills were taught and assessed explicitly, implicitly, or were absent in a range of undergraduate science assessment tasks (n = 35) from four research-intensive Australian universities. Results indicate that 10 of the 12 core science communication skills used for evaluation were absent from more than 50% of assessment tasks and 77.14% of all assessment tasks taught less than 5 core communication skills explicitly. The design of assessment tasks significantly affected whether communication skills were taught explicitly. Prominent trends were that communication skills in tasks aimed at non-scientific audiences were taught more explicitly than in tasks aimed at scientific audiences, and the majority of group and multimedia tasks taught communication elements more explicitly than individual, or written and oral tasks. Implications for science communication in the BSc and further research are discussed.

This paper outlines key findings from a research study into communication training programmes for public engagement with STEM (science, technology, engineering and mathematics. The research focused on training in direct communication methods, (as separate from media training and encompassed both trainers and trainees, the latter group spanning across both scientists and explainers. The findings indicated that training courses are effective at increasing involvement in science communication events and trainees feel more confident and able to engage due to training. An interactive style was found to be a key element of training courses. Demonstrations of good practice followed by own performance with feedback were also important, preferably involving a ‘real’ audience. A list of guidelines on best practice has been developed which offers practical advice.

    Team science is advocated to speed the pace of scientific discovery, yet the goals of collaborative practice in nursing science and the responsibilities of nurse stakeholders are sparse and inconclusive. The purpose of this study was to examine nurse scientists' views on collaborative research as part of a larger study on standards of scientific conduct. Web-based descriptive survey of nurse scientists randomly selected from 50 doctoral graduate programs in the United States. Nearly forty percent of nurse respondents were not able to identify good collaborative practices for the discipline; more than three quarters did not know of any published guidelines available to them. Successful research collaborations were challenged by different expectations of authorship and data ownership, lack of timeliness and communication, poorly defined roles and responsibilities, language barriers, and when they involve junior and senior faculty working together on a project. Individual and organizational standards, practices, and policies for collaborative research needs clarification within the discipline. Copyright © 2015 Elsevier Inc. All rights reserved.

    2017-01-01

    This Springer Brief provides theory, practical guidance, and support tools to help designers create complex, valid assessment tasks for hard-to-measure, yet crucial, science education standards. Understanding, exploring, and interacting with the world through models characterizes science in all its branches and at all levels of education. Model-based reasoning is central to science education and thus science assessment. Current interest in developing and using models has increased with the release of the Next Generation Science Standards, which identified this as one of the eight practices of science and engineering. However, the interactive, complex, and often technology-based tasks that are needed to assess model-based reasoning in its fullest forms are difficult to develop. Building on research in assessment, science education, and learning science, this Brief describes a suite of design patterns that can help assessment designers, researchers, and teachers create tasks for assessing aspects of model-based...

    2015-07-01

    Full Text Available The authors of this qualitative study set out to investigate self-assessment practices within the library profession. The researchers conducted semi-structured interviews with a purposeful sample of nine librarians coming from a range of library settings and possessing a diversity of library experience. Interviews were then transcribed and coded in NVIVO to identify emergent themes. This paper details some of the results of that study, highlighting motivations, limitations, and strategies with regard to self-assessment. The findings present a summary of a range of approaches to the practice of assessment as reported by the interviewees. One area of possible growth for our profession, as highlighted by the findings, is in the development of peer networks as a support for the individual practice of self-assessment. While the results of this small case study cannot be generalized, the authors hope these preliminary findings can open up the conversation around self-assessment both for individual librarians and for those librarians and managers working to shape their workplace culture.

    Champion, S. M.; Kunkel, K.

    2017-12-01

    The Sustained Assessment process has produced a suite of climate change reports: The Third National Climate Assessment (NCA3), Regional Surface Climate Conditions in CMIP3 and CMIP5 for the United States: Differences, Similarities, and Implications for the U.S. National Climate Assessment, Impacts of Climate Change on Human Health in the United States: A Scientific Assessment, The State Climate Summaries, as well as the anticipated Climate Science Special Report and Fourth National Climate Assessment. Not only are these groundbreaking reports of climate change science, they are also the first suite of climate science reports to provide access to complex metadata directly connected to the report figures and graphics products. While the basic metadata documentation requirement is federally mandated through a series of federal guidelines as a part of the Information Quality Act, Sustained Assessment products are also deemed Highly Influential Scientific Assessments, which further requires demonstration of the transparency and reproducibility of the content. To meet these requirements, the Technical Support Unit (TSU) for the Sustained Assessment embarked on building a system for not only collecting and documenting metadata to the required standards, but one that also provides consumers unprecedented access to the underlying data and methods. As our process and documentation have evolved, the value of both continue to grow in parallel with the consumer expectation of quality, accessible climate science information. This presentation will detail the how the TSU accomplishes the mandated requirements with their metadata collection and documentation process, as well as the technical solution designed to demonstrate compliance while also providing access to the content for the general public. We will also illustrate how our accessibility platforms guide consumers through the Assessment science at a level of transparency that builds trust and confidence in the report

  1. Using Reflective Practice to Facilitate Conversations and Transform Instructional Practice for Middle School Science Teachers

    Science.gov (United States)

    Higdon, Robbie L.

    The process of teaching, especially inquiry, is complex and requires extended time for developing one's instructional practice (Loucks-Horsley, Stiles, Mundry, Love, & Hewson, 2010). The implementation of a continued cycle of self-reflection can engage teachers in analyzing their prior experiences and understandings about their instructional practice to promote the accommodation of new concepts and transform their practice. However, many teachers have difficulty engaging in the cognitive dissonance needed to identify those problems and promote their own growth without support. As one's professional practice becomes more repetitive and routine, it is difficult for the practitioner to recognize opportunities in which to contemplate one's habitual actions (Schon, 1983). In this multi-case study, two middle school science teachers who were engaged within a sustained professional development initiative participated in a series of one-on-one reflective dialogues regarding the decisions they made about the utilization of inquiry-based instruction. In addition, these teachers were asked to reflect upon the criteria used to determine how and when to implement these inquiry-based practices. These reflective dialogue sessions provided the opportunity to observe teacher conceptions and stimulate teacher cognitive dissonance about instructional practice. Qualitative analysis of data collected from these reflective dialogues along with informal and formal classroom observations of instructional practice uncovered diverse perceptions regarding the implementation of inquiry-based methods into present teaching practice. The use of reflective dialogue within the existing structure of the professional development initiative allowed for the facilitators of the professional development initiative to tailor ongoing support and their effective implementation of inquiry-based instruction. Additional research is needed to investigate the impact of reflective dialogue in achieving

    Full Text Available Introduction: The Informatics for Health congress, 24-26 April 2017, in Manchester, UK, brought together the Medical Informatics Europe (MIE conference and the Farr Institute International Conference. This special issue of the Journal of Innovation in Health Informatics contains 113 presentation abstracts and 149 poster abstracts from the congress. Discussion: The twin programmes of “Big Data” and “Digital Health” are not always joined up by coherent policy and investment priorities. Substantial global investment in health IT and data science has led to sound progress but highly variable outcomes. Society needs an approach that brings together the science and the practice of health informatics. The goal is multi-level Learning Health Systems that consume and intelligently act upon both patient data and organizational intervention outcomes. Conclusions: Informatics for Health demonstrated the art of the possible, seen in the breadth and depth of our contributions. We call upon policy makers, research funders and programme leaders to learn from this joined-up approach.

    In 2012, the Mars Science Laboratory (MSL) mission will pioneer the next generation of robotic Entry, Descent, and Landing (EDL) systems, by delivering the largest and most capable rover to date to the surface of Mars. As with previous Mars landers, atmospheric conditions during entry, descent, and landing directly impact the performance of MSL's EDL system. While the vehicle's novel guided entry system allows it to "fly out" a range of atmospheric uncertainties, its trajectory through the atmosphere creates a variety of atmospheric sensitivities not present on previous Mars entry systems and landers. Given the mission's stringent landing capability requirements, understanding the atmosphere state and spacecraft sensitivities takes on heightened importance. MSL's guided entry trajectory differs significantly from recent Mars landers and includes events that generate different atmospheric sensitivities than past missions. The existence of these sensitivities and general advancement in the state of Mars atmospheric knowledge has led the MSL team to employ new atmosphere modeling techniques in addition to past practices. A joint EDL engineering and Mars atmosphere science and modeling team has been created to identify the key system sensitivities, gather available atmospheric data sets, develop relevant atmosphere models, and formulate methods to integrate atmosphere information into EDL performance assessments. The team consists of EDL engineers, project science staff, and Mars atmospheric scientists from a variety of institutions. This paper provides an overview of the system performance sensitivities that have driven the atmosphere modeling approach, discusses the atmosphere data sets and models employed by the team as a result of the identified sensitivities, and introduces the tools used to translate atmospheric knowledge into quantitative EDL performance assessments.

  5. Teacher Transformation: An Exploration of Science Teachers' Changing Professional Identities, Knowledge, and Classroom Practices

    Science.gov (United States)

    Whitacre, Michelle Phillips

    This qualitative, multiple case study examines five teachers' experiences with a National Science Foundation-funded professional development (PD) program focused on science literacy. Using a three dimensional conceptual framework combining transformative learning theory, communities of practice, and sociocultural conceptions of identity it explores: the ways the "Science Literacy through Science Journalism" (SciJourn) project built professional community and influenced teacher learning; the influence of the project on participating science teachers' professional identities, knowledge, and classroom practices; and the ways teachers were or were not transformed by participation in the project. To this end, data from surveys and phenomenological interviews were analyzed through qualitative textual analysis and narrative analysis. Four of the teachers experienced a change in their stories to live by, aka, an identity shift. Three predominant themes emerged across these cases. These included a changed conceptualization of science literacy, the importance of student engagement and authenticity, and the value of SciJourn's professional development and community. The changed conceptualization of science literacy was particularly salient as it challenged these teachers' assumptions, led them to rethink how they teach science literacy, and also influenced them to re-evaluate their teaching priorities beyond the PD. Consequently, this study concludes that PD efforts should focus as much, or more, on influencing teachers' ideas regarding what and how they teach and less on teaching strategies. A close comparison between two teachers' diverging experiences with the program showed that student engagement played a significant role in teachers' perceptions of the value of project, suggesting that whether or not teachers sustain a new practice is closely tied to their students' feedback. Additionally, this analysis showed that a teacher's individualized needs and sense of efficacy

    2017-08-01

    This paper offers analyses from a project examining the construction of narrative assessments within elementary science investigations. We examined how positioning children to express understandings through narrative assessments created spaces for revealing children's perspectives on classroom experiences with their teachers and each other. Four findings emerged. First, transformation of practice requires a change of the teacher's role. Second, children's narrations provided a platform for elaborating their understandings. Third, our work illustrates the critical role of trust and time in working towards inclusive assessment practices. Lastly, dialogue around the children's products illustrates how they made decisions and challenges normative ideas of what children can or cannot do or know. Overall, we highlight how dialogue became a way for adults and children to cross boundaries of age and knowledge hierarchies in the construction of science assessments.

    Assessment and monitoring of client health and fitness is a key part of fitness professionals' practices. However, little is known about prevalence of this practice. This study describes the assessment/monitoring practices of a large sample of Australian fitness professionals. Cross-sectional. In 2014, 1206 fitness professionals completed an online survey. Respondents reported their frequency (4 point-scale: [1] 'never' to [4] 'always') of assessment/monitoring of eight health and fitness constructs (e.g. body composition, aerobic fitness). This was classified as: (i) 'high' ('always' assessing/monitoring ≥5 constructs); (ii) 'medium' (1-4 constructs); (iii) 'low' (0 constructs). Classifications are reported by demographic and fitness industry characteristics. The odds of being classified as a 'high assessor/monitor' according to social ecological correlates were examined using a multiple-factor logistic regression model. Mean age of respondents was 39.3 (±11.6) years and 71.6% were female. A total of 15.8% (95% CI: 13.7%-17.9%) were classified as a 'high' assessor/monitor. Constructs with the largest proportion of being 'always' assessed were body composition (47.7%; 95% CI: 45.0%-50.1%) and aerobic fitness (42.5%; 95% CI: 39.6%-45.3%). Those with the lowest proportion of being 'always' assessed were balance (24.0%; 95% CI: 24.7%-26.5%) and mental health (20.2%; 95% CI: 18.1%-29.6%). A perceived lack of client interest and fitness professionals not considering assessing their responsibility were associated with lower odds of being classified as a 'high assessor/monitor'. Most fitness professionals do not routinely assess/monitor client fitness and health. Key factors limiting client health assessment and monitoring include a perceived lack of client interest and professionals not considering this their role. Copyright © 2017.

    Full Text Available Abstract Background In recent years waterpipe smoking has become a popular practice amongst young adults in eastern Mediterranean countries, including Iran. The aim of this study was to assess waterpipe smoking perceptions and practices among first-year health sciences university students in Iran and to identify factors associated with the initiation and maintenance of waterpipe use in this population. Results Out of 371 first-year health sciences students surveyed, 358 eight students completed a self-administered questionnaire in the classrooms describing their use and perceptions towards waterpipe smoking. Two hundred and ninety six responders met study inclusion criteria. Waterpipe smoking was common among first-year health sciences university students, with 51% of students indicating they were current waterpipe smokers. Women were smoking waterpipes almost as frequently as men (48% versus 52%, respectively. The majority of waterpipe smokers (75.5% indicated that the fun and social aspect of waterpipe use was the main motivating factor for them to continue smoking. Of waterpipe smokers, 55.3% were occasional smokers, using waterpipes once a month or less, while 44.7% were frequent smokers, using waterpipes more than once a month. A large number of frequent waterpipe smokers perceived that waterpipe smoking was a healthier way to use tobacco (40.6% while only 20.6% thought it was addictive. Compared to occasional smokers, significantly more frequent smokers reported waterpipe smoking was relaxing (62.5% vs. 26.2%, p = 0.002, energizing (48.5% vs. 11.4%, p = 0.001, a part of their culture (58.8% vs. 34.1%, p = 0.04, and the healthiest way to use tobacco (40.6% vs. 11.1%, p = 0.005. Conclusions Social and recreational use of waterpipes is widespread among first-year health sciences university students in Iran. Women and men were almost equally likely to be current waterpipe users. Public health initiatives to combat the increasing use of

  13. Supporting Beginning Teacher Planning and Enactment of Investigation-based Science Discussions: The Design and Use of Tools within Practice-based Teacher Education

    Science.gov (United States)

    Kademian, Sylvie M.

    Current reform efforts prioritize science instruction that provides opportunities for students to engage in productive talk about scientific phenomena. Given the challenges teachers face enacting instruction that integrates science practices and science content, beginning teachers need support to develop the knowledge and teaching practices required to teach reform-oriented science lessons. Practice-based teacher education shows potential for supporting beginning teachers while they are learning to teach in this way. However, little is known about how beginning elementary teachers draw upon the types of support and tools associated with practice-based teacher education to learn to successfully enact this type of instruction. This dissertation addresses this gap by investigating how a practice-based science methods course using a suite of teacher educator-provided tools can support beginning teachers' planning and enactment of investigation-based science lessons. Using qualitative case study methodologies, this study drew on video-records, lesson plans, class assignments, and surveys from one cohort of 22 pre-service teachers (called interns in this study) enrolled in a year-long elementary education master of the arts and teaching certification program. Six focal interns were also interviewed at multiple time-points during the methods course. Similarities existed across the types of tools and teaching practices interns used most frequently to plan and enact investigation-based discussions. For the focal interns, use of four synergistic teaching practices throughout the lesson enactments (including consideration of students' initial ideas; use of open-ended questions to elicit, extend, and challenge ideas; connecting across students' ideas and the disciplinary core ideas; and use of a representation to organize and highlight students' ideas) appeared to lead to increased opportunities for students to share their ideas and engage in data analysis, argumentation and

    2014-12-01

    NASA Earth science observations, models, analyses, and applications made significant contributions to numerous aspects of the Third National Climate Assessment (NCA) report and are contributing to sustained climate assessment activities. The agency's goal in participating in the NCA was to ensure that NASA scientific resources were made available to understand the current state of climate change science and climate change impacts. By working with federal agency partners and stakeholder communities to develop and write the report, the agency was able to raise awareness of NASA climate science with audiences beyond the traditional NASA community. To support assessment activities within the NASA community, the agency sponsored two competitive programs that not only funded research and tools for current and future assessments, but also increased capacity within our community to conduct assessment-relevant science and to participate in writing assessments. Such activities fostered the ability of graduate students, post-docs, and senior researchers to learn about the science needs of climate assessors and end-users, which can guide future research activities. NASA also contributed to developing the Global Change Information System, which deploys information from the NCA to scientists, decision makers, and the public, and thus contributes to climate literacy. Finally, NASA satellite imagery and animations used in the Third NCA helped the pubic and decision makers visualize climate changes and were frequently used in social media to communicate report key findings. These resources are also key for developing educational materials that help teachers and students explore regional climate change impacts and opportunities for responses.

    2006-01-01

    Under a grant to improve outcomes for students who are deaf or hard of hearing awarded to the Association of College Educators--Deaf/Hard of Hearing, a team identified content that all teachers of students who are deaf and hard of hearing must understand and be able to teach. Also identified were 20 practices associated with content standards (10 each, literacy and science/mathematics). Thirty-seven master teachers identified by grant agents rated the practices on a Likert-type scale indicating the maximum benefit of each practice and maximum likelihood that they would use the practice, yielding a likelihood-impact analysis. The teachers showed strong agreement on the benefits and likelihood of use of the rated practices. Concerns about implementation of many of the practices related to time constraints and mixed-ability classrooms were themes of the reviews. Actions for teacher preparation programs were recommended.

    2015-01-01

    This paper explores emerging practices in research data management in the arts, humanities and social sciences (AHSS). It will do so vis-à-vis current citation conventions and impact measurement for research in AHSS. Case study findings on research data inventoried at Goldsmiths', University of London will be presented. Goldsmiths is a UK research-intensive higher education institution which specialises in arts, humanities and social science research. The paper's aim is to raise awareness of the subject-specific needs of AHSS scholars to help inform the design of future digital tools for impact analysis in AHSS. Firstly, I shall explore the definition of research data and how it is currently understood by AHSS researchers. I will show why many researchers choose not to engage with digital dissemination techniques and ORCID. This discussion must necessarily include the idea that practice-based and applied AHSS research are processes which are not easily captured in numerical 'sets' and cannot be labelled electronically without giving careful consideration to what a group or data item 'represents' as part of the academic enquiry, and therefore how it should be cited and analysed as part of any impact assessment. Then, the paper will explore: the role of the monograph and arts catalogue in AHSS scholarship; how citation practices and digital impact measurement in AHSS currently operate in relation to authorship and how digital identifiers may hypothetically impact on metrics, intellectual property (IP), copyright and research integrity issues in AHSS. I will also show that, if we are to be truly interdisciplinary, as research funders and strategic thinkers say we should, it is necessary to revise the way we think about digital research dissemination. This will involve breaking down the boundaries between AHSS and other types of research.

  20. Symposium 1: Investigating Teaching Practices that Promote Learning in Science Lessons

    Directory of Open Access Journals (Sweden)

    Eduardo F. Mortimer

    2014-05-01

    Full Text Available In this talk we use the notion of communicative approach, as outlined in our book (Mortimer & Scott 2003, as a way of highlighting the science teaching practices carried out by two teachers, one Brazilian and the other British. The characteristics that emerge from these practices demonstrate that teaching for meaningful learning involves progressive shifting between authoritative and dialogic communicative approaches. On the one hand, dialogic discourse is open to different points of view. The discourse direction changes as ideas are introduced and explored and the teachers assume a neutral position, avoiding evaluative comments and encouraging and probing student ideas. On the other hand, authoritative discourse focuses on a single perspective, normally the school science view. The discourse direction is prescribed in advance and the authority of teacher is clear:  he/she acts as a gatekeeper to points of view, through reshaping, ignoring, rejecting student ideas. The relationship between dialogic and authoritative approaches is that dialogic exploration of both everyday and scientific views requires resolution through authoritative guidance by the teacher. In shifting between dialogic and authoritative discourses these two teachers shows a number of pedagogical skills: they sustain a line of speech and thought, through which ideas are introduced, reviewed and consolidated in a cumulative process involving the creation of temporal links. They also monitor and follow the students’ understanding. They sistematicaly progress from the phenomenon to the description and explanation. And they select carefully developed activities to ensure the advancement of the scientific story. They also show affective and emotional skills, systematically encouraging the participation of all members of the class,offering approval, modeling the enthusiasm, recalling individual ideas and arguments of the students and linking to their names, and being consistent
