    2012-12-01

    As part of newly funded initiative, the Wolfson OpenScience Laboratory, we are linking a tool for inquiry based learning, nQuire (http://www.nquire.org.uk) with the virtual microscope for Earth science (http://www.virtualmicroscope.co.uk) to allow students to undertake projects and gain from inquiry based study thin sections of rocks without the need for a laboratory with expensive petrological microscopes. The Virtual Microscope (VM) was developed for undergraduate teaching of petrology and geoscience, allowing students to explore rock hand specimens and thin sections in a browser window. The system is based on HTML5 application and allows students to scan and zoom the rocks in a browser window, view in ppl and xpl conditions, and rotate specific areas to view birefringence and pleochroism. Importantly the VM allows students to gain access to rare specimens such as Moon rocks that might be too precious to suffer loss or damage. Experimentation with such specimens can inspire the learners' interest in science and allows them to investigate relevant science questions. Yet it is challenging for learners to engage in scientific processes, as they may lack scientific investigation skills or have problems in planning their activities; for teachers, managing inquiry activities is a demanding task (Quintana et al., 2004). To facilitate the realization of inquiry activities, the VM is being integrated with the nQuire tool. nQuire is a web tool that guides and supports students through the inquiry process (Mulholland et al., 2011). Learners are encouraged to construct their own personally relevant hypothesis, pose scientific questions, and plan the method to answer them. Then, the system enables users to collect and analyze data, and share their conclusions. Teachers can monitor their students' progress through inquiries, and give them access to new parts of inquiries as they advance. By means of the integration of nQuire and the VM, inquiries that involve collecting data

  11. Acquisition and Retention of STEM Concepts through Inquiry Based Learning

    Science.gov (United States)

    Lombardi, Candice

    This study explores the integration of STEM (science, technology, engineering, and mathematics) concepts through inquiry based learning. Students are exposed to a constructivist style learning environment where they create understanding for themselves. This way of learning lets students plan and justify their ideas and beliefs while discussing and examining the ideas of their classmates. Students are engaged in solving a scientific problem in a meaningful, inquiry-based manner through hypothesis testing, experimentation, and investigation. This mode of learning introduces students to real life, authentic science experiences within the confines of a typical classroom. The focus of the unit is for the students to create connections and understanding about geography and the globe in order to ultimately identify the exact latitude and longitude of 10 mystery sites. The students learn about latitude and longitude and apply their knowledge through a set of clues to determine where their Mystery Class is located. Journey North provides an internationally accessed game of hide-and-seek called Mystery Class Seasons Challenge. Throughout this challenge, over the course of eleven weeks, students will record, graph, interpret and analysis data and research to ultimate identify the location of ten mystery locations. Students will track seasonal changes in sunlight while investigating, examining and researching clues to find these ten secret sites around the world. My research was done to prove the success of students' ability to learn new mathematics, science, technology and engineering concepts through inquiry based design.

    Active learning pedagogies play an important role in enhancing higher order cognitive skills among the student community. In this work, a laboratory course for first year engineering chemistry is designed and executed using an inquiry-based learning pedagogical approach. The goal of this module is to promote higher order thinking skills in chemistry. Laboratory exercises are designed based on Bloom's taxonomy and a just-in-time facilitation approach is used. A pre-laboratory discussion outlining the theory of the experiment and its relevance is carried out to enable the students to analyse real-life problems. The performance of the students is assessed based on their ability to perform the experiment, design new experiments and correlate practical utility of the course module with real life. The novelty of the present approach lies in the fact that the learning outcomes of the existing experiments are achieved through establishing a relationship with real-world problems.

    2011-07-01

    This study focuses on elementary teachers' comprehension of flooding before and after inquiry-based professional development (PD). There was an improvement in teachers' understanding toward a normative view from pre- to post-test (n = 17, mean gain = 4.3, SD = 3.27). Several misunderstandings and a general lack of knowledge about flooding emerged from the geoscience content two-tier pre-test, some of which persisted throughout the PD seminar while other responses provided evidence of teachers' improved understanding. The concepts that teachers struggled with were also apparent upon examining teachers' reflections upon their learning and teaching practices throughout the seminar. Teachers were challenged as they attempted to add new academic language, such as storm surge and discharge, to their prior understandings. Flooding concepts that teachers showed the least improvement on included analyzing a topographic region, reading a map image, and hydrograph interpretation. Teachers' greatest areas of improved understanding occurred in understanding the probability and role of ground conditions in flooding events. Teachers demonstrated considerable growth in their understanding of some flooding concepts through scaffolded inquiry lessons modeled throughout the PD. Those teachers who had greater prior knowledge and demonstrated more use of self-regulated learning showed the most change toward a normative view of flooding. The explicit modeling and participation in inquiry-based science activities and written responses to self-regulatory learning prompts throughout the seminar supported teachers' learning.

    This research suggests utilizing collaborative learning among high school students for better performance on ecology inquiry-based projects. A case study of nine 12th grade students who participated in collaborative learning sessions in the open field and in class is examined. The results show that the students concentrated on discussing the methods of measurement and observation in the open field, rather than the known methods from class or from the laboratory. Another major part of their discussions concentrated on knowledge construction. Knowledge construction occurred between students with same or similar learning abilities. The role of the teacher in these discussions was crucial: she had to deal with and dispel misconceptions; and she had to bridge the gap between low-ability and high-ability students, for enabling meaningful learning to occur. The article ends with a number of recommendations for using collaborative learning as a tool for achieving meaningful learning in high school ecology inquiry-based projects.

  4. Teaching numerical methods with IPython notebooks and inquiry-based learning

    KAUST Repository

    Ketcheson, David I.

    2014-01-01

    A course in numerical methods should teach both the mathematical theory of numerical analysis and the craft of implementing numerical algorithms. The IPython notebook provides a single medium in which mathematics, explanations, executable code, and visualizations can be combined, and with which the student can interact in order to learn both the theory and the craft of numerical methods. The use of notebooks also lends itself naturally to inquiry-based learning methods. I discuss the motivation and practice of teaching a course based on the use of IPython notebooks and inquiry-based learning, including some specific practical aspects. The discussion is based on my experience teaching a Masters-level course in numerical analysis at King Abdullah University of Science and Technology (KAUST), but is intended to be useful for those who teach at other levels or in industry.

    Full Text Available Motivation is an important factor for inquiry-based learning, so creative design of learning resources and materials is critical to enhance students’ motivation and hence their cognition. Modern dentistry is moving towards “electronic patient records” for both clinical treatment and teaching. Study models have long been an essential part of dental records. Traditional plaster casts are, however, among the last type of clinical record in the dental field to be converted into digital media as virtual models. Advantages of virtual models include: simpler storage; reduced risk of damage, disappearance, or misplacement; simpler and effective measuring; and easy transferal to colleagues. In order to support student engagement with the rapidly changing world of digital dentistry, and in order to stimulate the students’ motivation and depth of inquiry, this project aims to introduce virtual models into a Bachelor and Dental Surgery (BDS curriculum. Under a “blended” e-learning philosophy, students are first introduced to the new software then 3-D models are incorporated into inquiry-based problems as stimulus materials. Face-to-face tutorials blend virtual model access via interactive whiteboards (IWBs. Students’ perceptions of virtual models including motivation and cognition as well as the virtual models’ functionality were rated after a workshop introducing virtual models and plaster models in parallel. Initial student feedback indicates that the 3-D models have been generally well accepted, which confirmed the functionality of the programme and the positive perception of virtual models for enhancing students’ learning motivation. Further investigation will be carried out to assess the impact of virtual models on students’ learning outcomes.

    Full Text Available The inquiry-based Family Maths professional development programme, offered by the Nelson Mandela Metropolitan University, attempts not only to support the transformative education practices targeted by the South African National Department of Education, but also to extend them beyond the school walls to the community at large. This study investigates the extent to which this programme develops facilitators’ ability to implement inquiry-based learning. The research undertaken uses both qualitative and quantitative methods in an empirical study of 39 facilitators. The facilitators’ inquiry beliefs and ability to implement inquiry learning was measured by means of questionnaires, observation schedules and interviews. Data generated by the study reveal that both the facilitators’ understanding and practice of inquiry improved as they progressed through the novice, intermediate and veteran categories of the Family Maths professional development programme.

    Geoscience and education faculty at The University of Akron jointly developed a series of inquiry-based learning modules aimed at both non-major and major student populations enrolled in introductory geology courses. These courses typically serve 2500 students per year in four to six classes of 40-160 students each per section. Twelve modules were developed that contained common topics and assessments appropriate to Earth Science, Environmental Geology and Physical Geology classes. All modules were designed to meet four primary learning objectives agreed upon by Department of Geology faculty. These major objectives include: 1) Improvement of student understanding of the scientific method; 2) Incorporation of problem solving strategies involving analysis, synthesis, and interpretation; 3) Development of the ability to distinguish between inferences, data and observations; and 4) Obtaining an understanding of basic processes that operate on Earth. Additional objectives that may be addressed by selected modules include: 1) The societal relevance of science; 2) Use and interpretation of quantitative data to better understand the Earth; 3) Development of the students' ability to communicate scientific results; 4) Distinguishing differences between science, religion and pseudo-science; 5) Evaluation of scientific information found in the mass media; and 6) Building interpersonal relationships through in-class group work. Student pre- and post-instruction progress was evaluated by administering a test of logical thinking, an attitude toward science survey, and formative evaluations. Scores from the logical thinking instrument were used to form balanced four-person working groups based on the students' incoming cognitive level. Groups were required to complete a series of activities and/or exercises that targeted different cognitive domains based upon Bloom's taxonomy (knowledge, comprehension, application, analysis, synthesis and evaluation of information).

    Current research indicates that inquiry-based learning should be guided in order to achieve optimal learning outcomes. The need for guidance is even greater when simulations are used because of their high information content and the difficulty of extracting information from them. Previous research on guidance for learning with simulations has concentrated on guidance provided by the simulation. Little research has been done on the role of the teacher in guiding learners with inquiry-based activities using simulations. This descriptive study focuses on guidance provided during small group investigations; pre-service teachers (n = 8) guided third and fifth graders using a particular simulation. Data was collected using screen capture videos. The data was analyzed using a combination of theory- and data-driven analysis. Forms of guidance provided by the simulation and by the teachers were divided into the same categories. The distribution of the guidance between the teacher and the simulation was also analyzed. The categories for forms of guidance provided by simulations proved to be applicable to guidance provided by the teachers as well. Teachers offered more various forms of guidance than the simulation. The teachers adapted their guidance and used different patterns to complement the guidance provided by the simulation. The results of the study show that guidance provided by teachers and simulations have different affordances, and both should be present in the classroom for optimal support of learning. This has implications for both teaching with simulations and development of new simulations.

    Full Text Available Increasing the opportunity for students to be involved in inquiry-based activities can improve engagement with content and assist in the development of analysis and critical thinking skills. The science laboratory has traditionally been used as a platform to apply the content gained through the lecture series. These activities have exposed students to experiments which test the concepts taught but which often result in a predicted outcome. To improve the engagement and learning outcomes of our large first year biology cohort, the laboratories were redeveloped. Superlabs were run with 100 students attending weekly sessions increasing the amount of contact time from previous years. Laboratories were redeveloped into guided-inquiry and educators facilitated teams of students to design and carry out an experiment. To analyse the impact of the redevelopment on student satisfaction and learning outcomes, students were surveyed and multiple choice exam data was compared before and after the redevelopment. Results suggest high levels of student satisfaction and a significant improvement in student learning outcomes. All disciplines should consider including inquiry-based activities as a methodology to improve student engagement and learning outcome as it fosters the development of independent learners.

    Full Text Available In order to implement models of reform-based history education in the classroom there is a fundamental need to address preservice and practicing teachers’ understanding of learning and teaching history, mindful of the role inquiry must play in the process. The project described in this paper employed a comparative case design to explore how prospective social studies educators perceived inquiry-based instruction and the extent to which it aligned with relevant history education for middle and secondary students. Results suggest that the process undertaken by the independent inquiry group may have an implicit impact on shaping how preservice teachers understand inquiry. Yet these preservice teachers included more inquiry-based activities in lesson plan products analyzed as part of this project. After the implementation of both means of learning about historical inquiry, many remained conflicted about what the ideal model of inquiry represents for student learning and at what ability level students are capable of engaging in inquiry in social studies.

    In order to fully attain the benefits of inquiry-based learning, instructors who typically employ the traditional lecture format need to make many adjustments to their approach. This change in styles can be intimidating and logistically difficult to overcome, both for instructors and students, such that a stepwise approach to this transformation is likely to be more manageable. In this session, I will describe a series of tools to promote inquiry-based learning that I am helping to implement and assess in classroom courses and student research projects. I will demonstrate the importance of integrating with existing institutional initiatives as well as recognizing how student development plays a key role in student engagement. Some of the features I will highlight include: defining both student learning outcomes and student development outcomes, converting content training to be self-directed and asynchronous, utilizing conceptests to help students practice thinking like scientists, and employing both objective pre/post assessment and student self-reflective assessment. Lastly, I will reflect on how the well-defined goal of teaching and research integration in the CAREER award solicitation resonated with me even as an undergraduate and helped inspire my early career.

  12. In harmony: inquiry based learning in a blended physics and music class

    Hechter, Richard P.; Bergman, Daniel

    2016-11-01

    The power of music to resonate within us transcends conventional boundaries established in cultural, geographic, and political contexts. In our world, as physics educators, so does the resonating of physics phenomena. Secondary level physics is a perfect place to blend these two genres. While advocating for STEM-based education is at the forefront of pedagogical reform, seldom do we use this cross-boundary vision as the foundation to teach and learn in true collaboration of science and arts classrooms. As music enthusiasts, and physics educators, we developed new resources for a blended music and physics class through inquiry-based learning activities. Punctuated with modern technology, we aimed our activities for an engaging learning experience towards developing conceptual understandings of sound and harmonics at the grade 11 level. The umbrella activity shared here was designed to engage a wide range of students through the universal language of music, and provide them a hands-on and minds-on experience to explore harmonics through both music and physics lenses. It is our intention to provide readers with an overview of the activity, a description of exemplar student-designed inquiry-based investigations, and helpful suggestions for potential for use in reader’s classrooms.

    2016-06-01

    Recent examples of high-impact teaching practices in the undergraduate chemistry laboratory that include course-based undergraduate research experiences and inquiry-based experiments require new approaches to assessing individual student learning outcomes. Instructors require tools and strategies that can provide them with insight into individual student contributions to collaborative group/teamwork throughout the processes of experimental design, data analysis, display and communication of their outcomes in relation to their research question(s). Traditional assessments in the form of laboratory notebooks or experimental reports provide limited insight into the processes of collaborative inquiry-based activities. A wiki environment offers a collaborative domain that can potentially support collaborative laboratory processes and scientific record keeping. In this study, the effectiveness of the wiki in supporting laboratory learning and assessment has been evaluated through analysis of the content and histories for three consenting, participating groups of students. The conversational framework has been applied to map the relationships between the instructor, tutor, students and laboratory activities. Analytics that have been applied to the wiki platform include: character counts, page views, edits, timelines and the extent and nature of the contribution by each student to the wiki. Student perceptions of both the role and the impact of the wiki on their experiences and processes have also been collected. Evidence has emerged from this study that the wiki environment has enhanced co-construction of understanding of both the experimental process and subsequent communication of outcomes and data. A number of features are identified to support success in the use of the wiki platform for laboratory notebooks.

    2012-01-01

    In order to increase scientific literacy and the knowledge of science and technology of Europe's citizens, the European Commission suggests a more student-centred implementation of natural sciences in education systems. Inquiry-based learning (IBL) is not only an accepted method to promote students' interest and motivation, it also helps students learn the scientific method and fosters their research skills. However, IBL is rarely used in European classrooms. The main reason is that due to the strict curricula teachers do not have the time for preparation and they do not feel well equipped and trained in the use of IBL methods in class. The Photonics Explorer programme addresses these problems on the European level. Within the programme, a pan-European collaboration of professors, teachers and photonics experts have developed the Photonics Explorer kit for the teaching of optics and light-related topics in physics across various European secondary school curricula. It is designed for intra-curricular use and contains specially designed, hands-on experimental components, worksheets based on guided IBL and multimedia material. Additionally, the kit provides a teacher guide with a suggested lesson outline and sufficient background information for each topic.

    2010-12-01

    An inquiry based learning exercise was designed for an upper division advanced inorganic laboratory course that meets one of the requirements for the Bachelor of Science degree in Chemistry and Biochemistry at the University of California, Santa Cruz. The content goals of this exercise were evaluation of whether a given solid state structure was previously known by using powder X-ray diffraction data, and understanding how the diffraction pattern relates to the crystal structure of the compound in question. The scientific process goals included searching a database to match the patterns and preparing data for oral presentations. The goals of the exercise were addressed via an activity allowing students to utilize real X-ray powder diffraction data to search and match with known structures in a database (International Crystal Structure Database) and to give an oral presentation. After students found their structures in the database, they prepared oral presentations justifying their choice for the match and their reasoning through structural analysis of the X-ray data. Students learned about X-ray diffraction theory in an inquiry type environment and gained valuable experience and confidence in presenting their findings using strong reasoning and communication skills. Assessment was implemented during active facilitation throughout the activity and during the final oral presentations.

  3. Inquiry-based learning, the nature of science, and computer technology: New possibilities in science education

    Directory of Open Access Journals (Sweden)

    John P Kubieck

    2005-02-01

    Full Text Available The teaching of science in the K-12 classroom has been less than successful. Students typically do not develop science literacy and do not understand the role and relevance of science in society. Inquiry-based learning is an approach which promises to improve science teaching by engaging students in authentic investigations, thereby achieving a more realistic conception of scientific endeavour as well as providing a more learner-centred and motivating environment. It can also be used to support teaching the nature of science. The inquiry approach, while lauded by educators, is still not prevalent in the classroom, and is often misused. This may be the result of multiple factors, such as amount of classroom time, lack of effective means for students to conduct independent investigations, the difficulty of incorporating abstract concepts with inquiry, and lack of teacher expertise and experience. Computer technology has evolved now to the point where it can greatly facilitate the use of inquiry learning on many levels, and provide new tools for representing the nature of science in the classroom. This use of technology to support new teaching approaches and objectives holds great promise for improving science education in the classroom, as long as the inherent limitations are recognized and technology is used as a tool rather than as a foundation.

    The observations of the Atmospheric Imaging Assembly aboard the Solar Dynamics Observatory (SDO-AIA) are expected to be groundbreaking within the field of heliophysics. To properly promote and explain the data produced by AIA, it is important that an innovative EPO effort be put forth. This has led to the development of "The AIA Solar Learning Center” (SLC), an inquiry-based educational website geared towards teaching about AIA and the Sun in general. The goal of the SLC is to provide K-12 students, teachers, parents, and homeschoolers with information and education about the Sun, primarily through hands-on activity modules that explain different aspects of our nearest star and the methods of observing it. While each module ultimately aims to impart information about the Sun or some related physical process, the activities also range across a host of different disciplines, including geology, chemistry, history, music, and art. In order to make the content applicable and accessible, activities are tailored to multiple difficulty levels, catering to different age groups. There is also a strong push towards facilitating teachers; activities are designed to fulfill specific teaching standards, and a host of additional teaching material is provided, including lesson plans and powerpoint presentations. Ultimately, the SLC aims to make science and the Sun inviting and accessible. The "Meet the Scientists” page will provide pictures and personal bios of participating scientists. Students will have the opportunity to interactively ask solar-related questions. There is even a host of lighter fare, such as a solar music playlist and links to relevant Facebook pages.

  6. The effect of guided inquiry-based instruction in secondary science for students with learning disabilities

    Science.gov (United States)

    Eliot, Michael H.

    Students with learning disabilities (SWLDs) need to attain academic rigor to graduate from high school and college, as well as achieve success in life. Constructivist theories suggest that guided inquiry may provide the impetus for their success, yet little research has been done to support this premise. This study was designed to fill that gap. This quasi-experimental study compared didactic and guided inquiry-based teaching of science concepts to secondary SWLDs in SDC science classes. The study examined 38 students in four classes at two diverse, urban high schools. Participants were taught two science concepts using both teaching methods and posttested after each using paper-and-pencil tests and performance tasks. Data were compared to determine increases in conceptual understanding by teaching method, order of teaching method, and exposure one or both teaching methods. A survey examined participants' perceived self-efficacy under each method. Also, qualitative comparison of the two test formats examined appropriate use with SWLDs. Results showed significantly higher scores after the guided inquiry method on concept of volume, suggesting that guided inquiry does improve conceptual understanding over didactic instruction in some cases. Didactic teaching followed by guided inquiry resulted in higher scores than the reverse order, indicating that SWLDs may require direct instruction in basic facts and procedures related to a topic prior to engaging in guided inquiry. Also application of both teaching methods resulted in significantly higher scores than a single method on the concept of density, suggesting that SWLDs may require more in depth instruction found using both methods. No differences in perceived self-efficacy were shown. Qualitative analysis both assessments and participants' behaviors during testing support the use of performance tasks over paper-and-pencil tests with SWLDs. Implications for education include the use of guided inquiry to increase SWLDs

    Koppers, A. A.; Staudigel, H.

    2007-12-01

    Most Education and Professional Outreach (EPO) by scientists reaches relatively small audiences. Most scientists also see their contributions to K-12 teaching rather limited due to their lack of experience in primary and secondary school education. These limitations remain a major barrier in bridging the gap between science and education, and in optimizing the effectiveness of EPO by scientists. As part of the Enduring Resources for Earth Science Education (ERESE) project, we have started to use web- templates in our EPO creation (http://earthref.org/ERESE). These templates are now being developed into web- based tools and services that will be served from the ERESE website and archived by the National Science Digital Library (NSDL). At EarthRef.org these EPO objects can be linked to teaching materials in the ERDA digital archive that can be displayed in a fashion allowing selection based on expert level and file type, in what we dubbed the "resource matrix" view. This is a powerful search mechanism for learners of all levels in which they can pre-screen materials to their own level, while allowing them to venture up to higher expert levels or to explore more simple cases at lower levels. This stimulates inquiry- based learning by permitting as much roaming freedom as possible in a "science-data- based" online environment. The current EarthRef.org and ERESE collections include websites for scientific projects, for classes taught and for expeditions, as well as a wide range of materials including press releases, video footage, science illustrations, interviews, data and diagrams, student reports and lesson plans. This collection is representative for EPO in any STEM discipline and provides much interesting materials that are useful for education. Our main goal is to provide scientists with tools so they can obtain an easy-to-use and highly leveraged outlet for their EPO efforts, where they can reach substantial numbers of learners and educators, and where their

  8. Discovering Plate Boundaries Update: Builds Content Knowledge and Models Inquiry-based Learning

    Science.gov (United States)

    2009-12-01

    Discovering Plate Boundaries (DPB) is a jigsaw-structured classroom exercise in which students explore the fundamental datasets from which plate boundary processes were discovered. The exercise has been widely used in the past ten years as a classroom activity for students in fifth grade through high school, and for Earth Science major and general education courses in college. Perhaps more importantly, the exercise has been used extensively for professional development of in-service and pre-service K-12 science teachers, where it simultaneously builds content knowledge in plate boundary processes (including natural hazards), models an effective data-rich, inquiry-based pedagogy, and provides a set of lesson plans and materials which teachers can port directly into their own classroom (see Pringle, et al, this session for a specific example). DPB is based on 4 “specialty” data maps, 1) earthquake locations, 2) modern volcanic activity, 3) seafloor age, and 4) topography and bathymetry, plus a fifth map of (undifferentiated) plate boundary locations. The jigsaw is structured so that students are first split into one of the four “specialties,” then re-arranged into groups with each of the four specialties to describe the boundaries of a particular plate. We have taken the original DPB materials, used the latest digital data sets to update all the basic maps, and expanded the opportunities for further student and teacher learning. The earthquake maps now cover the recent period including the deadly Banda Aceh event. The topography/bathymetry map now has global coverage and uses ice-free elevations, which can, for example, extend to further inquiry about mantle viscosity and loading processes (why are significant portions of the bedrock surface of Greenland and Antarctica below sea level?). The volcanic activity map now differentiates volcano type and primary volcanic lithology, allowing a more elaborate understanding of volcanism at different plate boundaries

    A pedagogic intervention, in the form of an inquiry-based peer-assisted learning project (as a practical student-led bioinformatics module), was assessed for its ability to increase students' engagement, practical bioinformatic skills and process-specific knowledge. Elements assessed were process-specific knowledge following module completion, qualitative student-based module evaluation and the novelty, scientific validity and quality of written student reports. Bioinformatics is often the starting point for laboratory-based research projects, therefore high importance was placed on allowing students to individually develop and apply processes and methods of scientific research. Students led a bioinformatic inquiry-based project (within a framework of inquiry), discovering, justifying and exploring individually discovered research targets. Detailed assessable reports were produced, displaying data generated and the resources used. Mimicking research settings, undergraduates were divided into small collaborative groups, with distinctive central themes. The module was evaluated by assessing the quality and originality of the students' targets through reports, reflecting students' use and understanding of concepts and tools required to generate their data. Furthermore, evaluation of the bioinformatic module was assessed semi-quantitatively using pre- and post-module quizzes (a non-assessable activity, not contributing to their grade), which incorporated process- and content-specific questions (indicative of their use of the online tools). Qualitative assessment of the teaching intervention was performed using post-module surveys, exploring student satisfaction and other module specific elements. Overall, a positive experience was found, as was a post module increase in correct process-specific answers. In conclusion, an inquiry-based peer-assisted learning module increased students' engagement, practical bioinformatic skills and process-specific knowledge. © 2016 by

    2009-12-01

    Teacher professional development centered about the Geosciences is necessary in order to train K-12 teachers about this science field and to effectively educate K-12 students about Earth processes. The partnership of industries, universities, and K-12 schools is a collaborative pathway to support these efforts by providing teachers access to technology, inquiry-based learning, and authentic field experiences within the Geosciences context. This research presents the results of Project SMARTER (Science and Mathematics Advancement and Reform utilizing Technology and Enhanced Resources), a co-lead industry-university partnership and teacher professional development workshop program that focused on technology and inquiry-based learning in the Geosciences. The workshop included fifteen teachers from five distressed counties in Mississippi as defined by the Appalachian Regional Commission. Three (one science, once math, one technology) 7-12 grade teachers were selected from each school district and worked together during activities as a team to foster a cooperative learning experience. The two week workshop trained teachers on the use of a variety of technologies including: Vernier Probes and software, TI-calculators and presenter, Mimio Boards, GPS receivers, Google Earth, Excel, PowerPoint, projectors, and the use of historic geologic datasets. Furthermore, teachers were trained on proper field collection techniques, the use of Hach Kits and field probes, and the interpretation of geologic data. Each daily program incorporated the use of technology-rich and inquiry-based activities into one of the five Earth spheres: atmosphere, lithosphere, biosphere, hydrosphere, and anthrosphere. Results from the pre-post technology attitude survey showed that participating teachers significantly (p plans to integrate technology in future classroom activities.

    Ruzhitskaya, Lanika

    The presented research study investigated the effects of computer-supported inquiry-based learning and peer interaction methods on effectiveness of learning a scientific concept. The stellar parallax concept was selected as a basic, and yet important in astronomy, scientific construct, which is based on a straightforward relationship of several components presented in a simple mathematical equation: d = 1/p. The simplicity of the concept allowed the researchers to explore how the learners construct their conceptual knowledge, build mathematical skills and transfer their knowledge beyond the learning settings. A computer-based tutorial Stellar Parallax Interactive Restricted and Unrestricted Tutorial (SPIRUT) was developed for this study, and was designed to aid students' knowledge construction of the concept either in a learner-controlled or a program-controlled mode. The first investigated method in the study was enhancing engagement by the means of scaffolding for inquiry, which included scripted prompts and called for students' predictions and reflections while working in the learner-controlled or the computer-controlled version of SPIRUT. A second form of enhancing engagement was through peers working cooperatively during the learning activities. The students' level of understanding of the concept was measured by (1) the number of correct answers on a conceptual test with (2) several questions that require knowledge transfer to unfamiliar situations and (3) their ability to calculate the stellar parallax and find distances to stars. The study was conducted in the University of Missouri among 199 non-science major students enrolled in an introductory astronomy course in the fall semester 2010. The participants were divided into two main groups: one was working with SPIRUT and another group was a control group and utilized a paper-based tutorial. The SPIRUT group was further divided into the learner-controlled and the program-controlled subgroups. Students

    Traditionally, university physics is taught in a lecture dominated style in which students are expected to passively absorb ideas that are presented in class. During the laboratory component, students often verify formulas given to them and expect that instructors will provide answers to their questions. In the Physics Department at Western Washington University we have implemented inquiry based labs in our calculus based introductory course. In these labs, instructors do not give students answers, but use guiding questions to help students develop their own understanding. In this poster, we present an example of an inquiry activity in which students use previously learned concepts of charge, conductors, polarization and grounding to build their own understanding of charging by induction. The goal is to promote not only conceptual understanding, but also student abilities to engage in multiple step reasoning involving more then one concept. After giving a brief synopsis of the activity, some data will be presented as a preliminary assessment of the effect of inquiry instruction on student learning.

  2. Using expectancy-value theory to explore aspects of motivation and engagement in inquiry-based learning in primary mathematics

    2017-03-01

    Inquiry-based learning (IBL) is a pedagogical approach in which students address complex, ill-structured problems set in authentic contexts. While IBL is gaining ground in Australia as an instructional practice, there has been little research that considers implications for student motivation and engagement. Expectancy-value theory (Eccles and Wigfield 2002) provides a framework through which children's beliefs about their mathematical competency and their expectation of success are able to be examined and interpreted, alongside students' perceptions of task value. In this paper, Eccles and Wigfield's expectancy-value model has been adopted as a lens to examine a complete unit of mathematical inquiry as undertaken with a class of 9-10-year-old students. Data were sourced from a unit (˜10 lessons) based on geometry and geometrical reasoning. The units were videotaped in full, transcribed, and along with field notes and student work samples, subjected to theoretical coding using the dimensions of Eccles and Wigfield's model. The findings provide insight into aspects of IBL that may impact student motivation and engagement. The study is limited to a single unit; however, the results provide a depth of insight into IBL in practice while identifying features of IBL that may be instrumental in bringing about increased motivation and engagement of students in mathematics. Identifying potentially motivating aspects of IBL enable these to be integrated and more closely studied in IBL practises.

    The Computational Science Reference Desk is an online tool designed to provide educators in math, physics, astronomy, biology, chemistry, and engineering with information on how to use computational science to enhance inquiry based learning in the undergraduate and pre college classroom. The Reference Desk features a showcase of original content exploration activities, including lesson plans and background materials; a catalog of websites which contain models, lesson plans, software, and instructional resources; and a forum to allow educators to communicate their ideas. Many of the recent advances in astronomy rely on the use of computer simulation, and tools are being developed by CSERD to allow students to experiment with some of the models that have guided scientific discovery. One of these models allows students to study how scientists use spectral information to determine the makeup of the interstellar medium by modeling the interstellar extinction curve using spherical grains of silicate, amorphous carbon, or graphite. Students can directly compare their model to the average interstellar extinction curve, and experiment with how small changes in their model alter the shape of the interstellar extinction curve. A simpler model allows students to visualize spatial relationships between the Earth, Moon, and Sun to understand the cause of the phases of the moon. A report on the usefulness of these models in two classes, the Computational Astrophysics workshop at The Shodor Education Foundation and the Conceptual Astronomy class at the University of North Carolina at Greensboro, will be presented.

    We have developed and tested two linked but separable structured inquiry exercises using a set of Drosophila melanogaster GAL4 enhancer trap strains for an upper-level undergraduate laboratory methods course at Bucknell University. In the first, students learn to perform inverse PCR to identify the genomic location of the GAL4 insertion, using FlyBase to identify flanking sequences and the primary literature to synthesize current knowledge regarding the nearest gene. In the second, we cross each GAL4 strain to a UAS-CD8-GFP reporter strain, and students perform whole mount CNS dissection, immunohistochemistry, confocal imaging, and analysis of developmental expression patterns. We have found these exercises to be very effective in teaching the uses and limitations of PCR and antibody-based techniques as well as critical reading of the primary literature and scientific writing. Students appreciate the opportunity to apply what they learn by generating novel data of use to the wider research community.

    Full Text Available The purpose of this study was to examine the effects of four-year integrated information literacy instruction via a framework of inquiry-based learning on elementary students’ memory and comprehension. Moderating factors of students’ academic achievement was another focus of this study. The subjects were 72 students who have participated in this study since they entered an elementary school in Chiayi district. This elementary school adopted the integrated information literacy instruction, designed by the researchers and elementary school teachers, and integrated it into various subject matters via a framework of inquiry-based learning, such as Super 3 and Big6 models. A series of inquiry-based integrated information literacy instruction has been implemented since the second semester of the subjects’ first grade. A total of seven inquiry learning projects has been implemented from grade one through grade four. Fourteen instruments were used as pretests and posttests to assess students’ factual recall and conceptual understanding of subject contents in different projects. The results showed that inquiry-based integrated information literacy instruction couldhelp students memorize facts and comprehend concepts of subject contents. Regardless ofacademic achievements, if students would like to devote their efforts to inquiry processes, their memory and comprehension of subject contents improvedeffectively. However, students of low-academic achievement might need more time to be familiar with the inquiry-based learning strategy.

    Professionals in science, technology, engineering, and mathematics (STEM) fields do not reflect the diversity of the US population. Among the most effective ways to attract and retain underrepresented students in STEM disciplines is to provide opportunities for participation in the scientific process and interaction with practicing scientists. Project HEAT (Hot Environments, Animals, & Temperature) is "boot-camp"-style workshop aimed at increasing interest in STEM topics among underrepresented, first-generation, college-bound middle school students. Linking to our NASA-funded research project "Desert Birds in a Warming World", we focused on how surprisingly variable temperature is in space and time, why temperature is important to plants, animals, and people, and how we measure temperature in the field and from space. Perhaps more importantly, this theme was a vehicle for students to experience science as a process: field observations, brainstorming questions and hypotheses, designing experiments to test them, and analyzing and reporting their data. The centerpiece was a set of experiments with small temperature sensors and radiation shields that teams of students designed, executed at a local park, analyzed, and reported. Two years of pre and post assessments revealed that Project HEAT participants increased understanding in content areas and showed slight increases in STEM interest. Year two results were markedly stronger than year one in both assessments as well as our perception. We attribute this to earlier summer timing of the workshop, a change from two half-day weeks to one full-day week, and a more age-homogeneous selection of students. In comments, participants expressed their special enjoyment of the hands-on nature of the program and the outdoor learning. Though providing such opportunities can be challenging, our experience here suggests that it can be worth while. Project HEAT also benefited our cadre of graduate student mentors by providing exposure

    How effective of a mentor are you? Have you thought much about this question? Have you participated in training to become a better mentor? For many academics, the typical three answers are "pretty good, I think ... why wouldn't I be?!"; "I am right now while reading this;" "Uh, no." The University of Wisconsin-Madison has developed a program called Research Mentor Training to help train scientists in myriad STEM (science, technology, engineering and mathematics) disciplines, including astronomy, for their crucial role of mentoring the next generation. Most of the field testing to date has focused on graduate students, post-docs, academic staff, and faculty mentoring undergraduate students who are participating in summer research experiences. The materials have proven quite effective in other areas as well, with only modest modifications. For example, several faculty cohorts concentrating on mentoring graduate students and post-docs have completed the training. In addition, the materials are used to prepare graduate students and undergraduates to mentor high school students. The preferred venue for the mentor training program is a seminar meeting one hour per week for 8 to 9 weeks, plus readings and outside activities, including mentoring a student. However, the structure is flexible, and some meaningful learning can occur in a single 90-minute interactive workshop like the one presented at the 2009 ASP annual meeting, "Science Education and Outreach: Forging a Path to the Future." All of the materials, including case studies, facilitator notes and guidelines, plus reading lists, are available online for no charge (http://researchmentortraining.org). Users can select pre-built curricula, or they can customize a package using a "shopping cart" interface.

  15. Optimizing students' motivation in inquiry-based learning environments: The role of instructional practices

    Science.gov (United States)

    Kempler, Toni M.

    The influence of inquiry science instruction on the motivation of 1360 minority inner-city seventh graders was examined. The project-based curriculum incorporates motivating features like real world questions, collaboration, technology, and lesson variety. Students design investigations, collect and analyze data, and create artifacts; challenging tasks require extensive use of learning and metacognitive strategies. Study 1 used Structural Equation Modeling to investigate student perceptions of the prevalence of project-based features, including real world connections, collaboration, academic press, and work norms, and their relation to interest, efficacy, cognitive engagement, and achievement. Perceptions of features related to different motivational outcomes, indicating the importance of using differentiated rather than single measures to study motivation in context. Cognitive engagement was enhanced by interest and efficacy but did not influence achievement, perhaps because students were not proficient strategy users and were new to inquiry. Study 2 examined the relationship between instructional practices and motivation. The 23 teachers in study 1 were observed six times during one unit. Observations focused on curriculum congruence, content accuracy, contextualization, sense making, and management and climate. A majority of teacher enactment was congruent with the curriculum, indicating that students experienced motivating features of project-based science. Hierarchical Linear Modeling showed that contextualization accounted for between-teacher variance in student interest, efficacy, and cognitive engagement; Teachers encouraged motivation through extended real world examples that related material to students' experiences. Cluster analysis was used to determine how patterns of practice affected motivation. Unexpectedly these patterns did not differentially relate to cognitive engagement. Findings showed that interest and efficacy were enhanced when teachers

    2016-01-01

    Background: Elementary Science Education is struggling with multiple challenges. National and State test results confirm the need for deeper understanding in elementary science education. Moreover, national policy statements and researchers call for increased exposure to engineering and technology in elementary science education. The basic motivation of this study is to suggest a solution to both improving elementary science education and increasing exposure to engineering and technology in it. Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students' science content learning of simple machines. Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups' scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group's pre- and post-scores by using paired t-tests. Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions. Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students' science content learning.

    This mixed method study examined the impact of a LEGO-based, engineering-oriented curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. This study takes a social constructivist theoretical stance that science learning involves learning scientific concepts and their relations to each other. From this perspective, students are active participants, and they construct their conceptual understanding through the guidance of their teacher. With the goal of better understanding the use of engineering education materials in classrooms the National Academy of Engineering and National Research Council in the book "Engineering in K-12 Education" conducted an in-depth review of the potential benefits of including engineering in K--12 schools as (a) improved learning and achievement in science and mathematics, (b) increased awareness of engineering and the work of engineers, (c) understanding of and the ability to engage in engineering design, (d) interest in pursuing engineering as a career, and (e) increased technological literacy (Katehi, Pearson, & Feder, 2009). However, they also noted a lack of reliable data and rigorous research to support these assertions. Data sources included identical written tests and interviews, classroom observations and videos, teacher interviews, and classroom artifacts. To investigate the impact of the design-based simple machines curriculum compared to the scientific inquiry-based simple machines curriculum on student learning outcomes, I compared the control and the experimental groups' scores on the tests and interviews by using ANCOVA. To analyze and characterize the classroom observation videotapes, I used Jordan and Henderson's (1995) method and divide them into episodes. My analyses revealed that the design-based Design a People Mover: Simple Machines unit was, if not better, as successful as the inquiry-based FOSS Levers and Pulleys unit in terms of students' content learning. I also

    Kelley, Sybil Schantz

    This mixed-methods study combined pragmatism, sociocultural perspectives, and systems thinking concepts to investigate students' engagement, thinking, and learning in science in an urban, K-8 arts, science, and technology magnet school. A grant-funded school-university partnership supported the implementation of an inquiry-based science curriculum, contextualized in the local environment through field experiences. The researcher worked as co-teacher of 3 sixth-grade science classes and was deeply involved in the daily routines of the school. The purposes of the study were to build a deeper understanding of the complex interactions that take place in an urban science classroom, including challenges related to implementing culturally-relevant instruction; and to offer insight into the role educational systems play in supporting teaching and learning. The central hypothesis was that connecting learning to meaningful experiences in the local environment can provide culturally accessible points of engagement from which to build science learning. Descriptive measures provided an assessment of students' engagement in science activities, as well as their levels of thinking and learning throughout the school year. Combined with analyses of students' work files and focus group responses, these findings provided strong evidence of engagement attributable to the inquiry-based curriculum. In some instances, degree of engagement was found to be affected by student "reluctance" and "resistance," terms defined but needing further examination. A confounding result showed marked increases in thinking levels coupled with stasis or decrease in learning. Congruent with past studies, data indicated the presence of tension between the diverse cultures of students and the mainstream cultures of school and science. Findings were synthesized with existing literature to generate the study's principal product, a grounded theory model representing the complex, interacting factors involved in

    2013-10-01

    Inquiry-based curricula are an essential tool for reforming science education yet the role of the teacher is often overlooked in terms of the impact of the curriculum on student achievement. Our research focuses on 22 teachers' use of a year-long high school urban ecology curriculum and how teachers' self-efficacy, instructional practices, curricular enactments and previous experience impacted student learning. Data sources included teacher belief surveys, teacher enactment surveys, a student multiple-choice assessment focused on defining and identifying science concepts and a student open-ended assessment focused on scientific inquiry. Results from the two hierarchical linear models indicate that there was significant variation between teachers in terms of student achievement. For the multiple-choice assessment, teachers who spent a larger percentage of time on group work and a smaller percentage of time lecturing had greater student learning. For the open-ended assessment, teachers who reported a higher frequency of students engaging in argument and sharing ideas had greater student learning while teachers who adapted the curriculum more had lower student learning. These results suggest the importance of supporting the active role of students in instruction, emphasising argumentation, and considering the types of adaptations teachers make to curriculum.

    Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students' learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students' inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists' practices is very much needed. Within this context there is a need to re-examine the science teachers' views of scientists and the cultural factors that might have an impact on teachers' views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative-qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers' cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists.

    Full Text Available In this study, the effects of interactive whiteboard supported inquiry- based learning approach on the academic achievement and motivation in modern physics teaching have been investigated and the views of prospective teachers toward the teaching supported by interactive whiteboard have been defined. In this study, patterned in the form of quasi-empirical model and supported with pre- and post-test control groups, data were collected by academic achievement tests, motivation scales and semi-structured interview forms. While traditional method was used to deliver lectures to the control group, interactive white board was used to deliver experimental group lectures enriched with activities such as simulations, videos and animations. Thus, it has been taken advantages of technology support in the processes of orienting and asking questions, identification of problems, hypothesis generation, testing and planning. In addition to these, the processes of measuring, drawing a graphs, controlling the variables and data interpretation have also been supported by simulations in lectures. As a result of applications, it has been achieved that the teaching materials used in experimental group significantly increased the students’ motivations and academic achievements. Moreover, it also has been obtained that prospective teachers had positive opinions; such as funny (amusing lecture environment, increasing the participation, concretization of the abstract concepts, facilitating the learning and providing permanence on applications in this study.

    2016-03-01

    We designed a 2-day inquiry activity where students learned about error analysis and coding practices in Python. Inquiry-based lessons provide students with opportunities to independently investigate scientific concepts and tools. A general structure is developed ahead of time and minimal, careful guidance provided during the activity, but students are given as much freedom as possible to explore the concepts at their own pace. We designed our activity to help students learn to write flexible, re-usable, and readable code. I will describe the lesson structure we initially designed, as well as what aspects worked for our students (or didn't) and our experience leading the activity.

    Sliding friction is usually introduced in high school, but rarely through activities in laboratory. A qualitative introduction to friction is presented by proposing exploration of different kind of materials in order to suggest which aspects can be relevant and which interaction is involved. Different quantitative experiments are proposed for studying Leonardo's laws for friction. The learning path was tested with two high school classes during an instruction trip at department. Students were engaged in the inquiry-based introductory activity and seemed to realize with care the measurements. However, the analysis of their reports shows some learning difficulties.

    Davis, L.; Weatherley, J.; Bhushan, S.; Khan, H.; de La Chica, S.; Deardorff, R.

    2004-12-01

    An exciting pilot program took place this summer, pioneering the development of Digital Library for Earth System Education (DLESE) Teaching Boxes with the Univ. of CA. Berkeley Museum of Paleontology, SF State Univ., USGS and 7 middle/high school teachers from the San Francisco area. This session will share the DLESE Teaching Box concept, explain the pilot program, and explore the tremendous opportunities for expanding this notion to embrace interdisciplinary approaches to learning about the Earth in the undergraduate science and pre-service teaching arenas. A Teaching Box is a metaphor for an online assembly of interrelated learning concepts, digital resources, and cohesive narration that bridges the gap between discrete resources and understanding. Within a Teaching Box, an instructor or student can pick a topic and see the concepts that build an understanding of that topic, explore online resources that support learning of those concepts, and benefit from the narration (the glue) that weaves concepts, activities, and background information together into a complete teaching/learning story. In this session, we will demonstrate the emerging Teaching Box prototypes and explore how this platform may promote STEM learning by utilizing DLESE tools and services in ways that begin to blur traditional disciplinary boundaries, overcome limitations of discipline-specific vocabularies, and foster collaboration. We will show ways in which new DLESE Web Services could support learning in this highly contextualized environment. We will see glimpses of how learners and educators will be able to modify or create their own Teaching Boxes specific to a unit of study or course, and perhaps share them with the Earth Science Education community. We will see ways to stay abreast of current Earth events, emerging research, and real-time data and incorporate such dynamic information into one learning environment. Services will be described and demonstrated in the context of Teaching

  2. Is adolescence a critical period for learning formal thinking skills? A case study investigating the development of formal thinking skills in a short-term inquiry-based intervention program

    Science.gov (United States)

    Towne, Forrest S.

    Current domestic and international comparative studies of student achievement in science are demonstrating that the U.S. needs to improve science education if it wants to remain competitive in the global economy. One of the causes of the poor performance of U.S. science education is the lack of students who have developed the formal thinking skills that are necessary to obtain scientific literacy. Previous studies have demonstrated that formal thinking skills can be taught to adolescents, however only 25% of incoming college freshman have these necessary skills. There is some evidence that adolescence (girls aged 11-13, boys aged 12-14) is a critical period where students must learn formal thinking skills, similar to the critical period that exists for young children learning languages. It is not known whether it is more difficult for students to learn formal thinking skills either prior to or following adolescence. The purpose of this quantitative case study is to determine whether adolescence is a critical period for students to learn formal thinking skills. The study also investigates whether a formal thinking skills focused program can improve students' intelligence. In this study 32 students who had not developed any formal thinking skills, ranging in age from 10-16, underwent an intensive four-week, inquiry-based, formal thinking skill intervention program that focused on two formal thinking skills: (1) the ability to control and exclude variables; and (2) the ability to manipulate ratios and proportionalities. The students undergoing the training were matched with control students by age, gender, formal thinking skill ability, and intelligence. The control group attended their traditional science course during the intervention periods. The results of the study showed that the intervention program was successful in developing students' formal thinking skills. The pre-adolescents (males, age 10-11, females, age 10) were unable to learn formal thinking skills

    Science.gov (United States)

    Boyd, Yolanda F.

    High school students need to graduate with 21st century skills to be college and career ready and to be competitive in a global marketplace. A positive trend exists favoring inquiry-based instructional practices that purportedly not only increase science content knowledge, but also 21 st century skill development. A suburban school district, Areal Township (pseudonym), implemented an inquiry-based science program based on this trend; however, the degree to which the program has been meeting students' needs for science content knowledge and 21st century skills development has not been explored. If we were to understand the process by which an inquiry-based science program contributes to attainment of science content and 21st century skill development, then we might be able to improve the delivery of the program and provide a model to be adopted by other schools. Therefore, the purpose of this descriptive case study was to engage with multiple stakeholders to formatively assess the successes and obstacles for helping students to achieve science content and 21st century skills through an inquiry-based curriculum. Using constructivist theory, this study aimed to address the following central research question: How does the implementation of an inquiry-based program within the Areal Township School District (ATSD) support the acquisition of science content knowledge and the development of 21st century skills? This study found that 21st century skill development is embedded in inquiry-based instructional practices. These practices engage students in meaningful learning that spirals in content and is measured using diverse assessments. Time to do inquiry-based science and adequate time for collegial collaboration were obstacles for educators in grades K-5. Other obstacles were turnkey professional development and a lack of ongoing program monitoring, as a result of imposed extrinsic factors from state and federal mandates. Lastly, it was discovered that not all parts of

    2013-06-01

    Full Text Available This study investigated the student performance in an inquiry learning course which integrated information literacy and reading strategies in a fourth-grade science class. The curriculum design was based on the Big6 model, which includes the stages of task definition, information seeking strategies, location & access, use of information, synthesis, and evaluation. The study duration was one semester. The data was gathered through participant observations, interviews, surveys, tests, and from documents generated in the course implementation. The results showed that the integration of information literacy and reading strategies instruction was feasible. The students performed well in information seeking strategies, locating & accessing information, using and synthesizing information. In contrast, their abilities in task definition and evaluation needed further improvement. Also, while the students did acquire various reading strategies during the inquiry process, they needed more exercises to internalize the skills. The performance on the acquisition of subject knowledge was also improved through the inquiry learning. The participating instructors considered that the collaboration between teachers of different subject matters was the key to a successful integrated instruction [Article content in Chinese

    Keys, Carolyn W.; Bryan, Lynn A.

    2001-08-01

    In this article we assert a potential research agenda for the teaching and learning of science as inquiry as part of the JRST series on reform in science education. Drawing on the theoretical frameworks of cognitive and sociocultural constructivism, cultural models of meaning, the dialogic function of language, and transformational models of teacher education, we propose that more research is needed in the areas of teachers' beliefs, knowledge, and practices of inquiry-based science, as well as, student learning. Because the efficacy of reform efforts rest largely with teachers, their voices need to be included in the design and implementation of inquiry-based curriculum. As we review the literature and pose future research questions, we propose that particular attention be paid to research on inquiry in diverse classrooms, and to modes of inquiry-based instruction that are designed by teachers.

  9. The science experience: The relationship between an inquiry-based science program and student outcomes

    Science.gov (United States)

    Poderoso, Charie

    Science education reforms in U.S. schools emphasize the importance of students' construction of knowledge through inquiry. Organizations such as the National Science Foundation (NSF), the National Research Council (NRC), and the American Association for the Advancement of Science (AAAS) have demonstrated a commitment to searching for solutions and renewed efforts to improve science education. One suggestion for science education reform in U.S. schools was a transition from traditional didactic, textbook-based to inquiry-based instructional programs. While inquiry has shown evidence for improved student learning in science, what is needed is empirical evidence of those inquiry-based practices that affect student outcomes in a local context. This study explores the relationship between instructional programs and curricular changes affecting student outcomes in the Santa Ana Unified District (SAUSD): It provides evidence related to achievement and attitudes. SAUSD employs two approaches to teaching in the middle school science classrooms: traditional and inquiry-based approaches. The Leadership and Assistance for Science Education Reform (LASER) program is an inquiry-based science program that utilizes resources for implementation of the University of California Berkeley's Lawrence Hall of Science Education for Public Understanding Program (SEPUP) to support inquiry-based teaching and learning. Findings in this study provide empirical support related to outcomes of seventh-grade students, N = 328, in the LASER and traditional science programs in SAUSD.

  10. Inquiry and groups: student interactions in cooperative inquiry-based science

    Woods-McConney, Amanda; Wosnitza, Marold; Sturrock, Keryn L.

    2016-03-01

    Science education research has recommended cooperative inquiry based science in the primary science context for more than two decades but after more than 20 years, student achievement in science has not substantially improved. This study, through direct observation and analysis, investigated content-related student interactions in an authentic inquiry based primary science class setting. Thirty-one upper primary students were videotaped working in cooperative inquiry based science activities. Cooperative talk and negotiation of the science content was analysed to identify any high-level group interactions. The data show that while all groups have incidences of high-level content-related group interactions, the frequency and duration of these interactions were limited. No specific pattern of preceding events was identified and no episodes of high-level content-related group interactions were immediately preceded by the teacher's interactions with the groups. This in situ study demonstrated that even without any kind of scaffolding, specific skills in knowing how to implement cooperative inquiry based science, high-level content-related group interactions did occur very briefly. Support for teachers to develop their knowledge and skills in facilitating cooperative inquiry based science learning is warranted to ensure that high-level content-related group interactions and the associated conceptual learning are not left to chance in science classrooms.

  11. The effect of inquiry-based, hands-on labs on achievement in middle school science

    Science.gov (United States)

    Miller, Donna Kaye Green

    The purpose of this quasi-experimental study was to measure the difference in science achievement between students who had been taught with an inquiry-based, hands-on pedagogical approach and those who had not. Improving student academic achievement and standardized test scores is the major objective of teachers, parents, school administrators, government entities, and students themselves. One major barrier to this academic success in Georgia, and the entire United States, has been the paucity of success in middle level science classes. Many studies have been conducted to determine the learning approaches that will best enable students to not only acquire a deeper understanding of science concepts, but to equip them to apply that new knowledge in their daily activities. Inquiry-based, hands-on learning involves students participating in activities that reflect methods of scientific investigation. The effective utilization of the inquiry-based learning approach demands inclusion of learners in a self-directed learning environment, the ability to think critically, and an understanding of how to reflect and reason scientifically. The treatment group using an inquiry-based, hands-on program did score slightly higher on the CRCT. However, the results revealed that there was not a significant difference in student achievement. This study showed that the traditionally instructed control group had slightly higher interest in science than the inquiry-based treatment group. The findings of this research study indicated that the NCLB mandates might need to be altered if there are no significant academic gains that result from the use of inquiry-based strategies.

  12. Inquiry-Based Science: Turning Teachable Moments into Learnable Moments

    Science.gov (United States)

    Haug, Berit S.

    2014-02-01

    This study examines how an inquiry-based approach to teaching and learning creates teachable moments that can foster conceptual understanding in students, and how teachers capitalize upon these moments. Six elementary school teachers were videotaped as they implemented an integrated inquiry-based science and literacy curriculum in their classrooms. In this curriculum, science inquiry implies that students search for evidence in order to make and revise explanations based on the evidence found and through critical and logical thinking. Furthermore, the curriculum material is designed to address science key concepts multiple times through multiple modalities (do it, say it, read it, write it). Two types of teachable moments were identified: planned and spontaneous. Results suggest that the consolidation phases of inquiry, when students reinforce new knowledge and connect their empirical findings to theory, can be considered as planned teachable moments. These are phases of inquiry during which the teacher should expect, and be prepared for, student utterances that create opportunities to further student learning. Spontaneous teachable moments are instances when the teacher must choose to either follow the pace of the curriculum or adapt to the students' need. One implication of the study is that more teacher support is required in terms of how to plan for and effectively utilize the consolidation phases of inquiry.

    Roehrig, G H; Michlin, M; Schmitt, L; MacNabb, C; Dubinsky, J M

    2012-01-01

    In science education, inquiry-based approaches to teaching and learning provide a framework for students to building critical-thinking and problem-solving skills. Teacher professional development has been an ongoing focus for promoting such educational reforms. However, despite a strong consensus regarding best practices for professional development, relatively little systematic research has documented classroom changes consequent to these experiences. This paper reports on the impact of sustained, multiyear professional development in a program that combined neuroscience content and knowledge of the neurobiology of learning with inquiry-based pedagogy on teachers' inquiry-based practices. Classroom observations demonstrated the value of multiyear professional development in solidifying adoption of inquiry-based practices and cultivating progressive yearly growth in the cognitive environment of impacted classrooms.

    Based on the cognitive-affective theory, the present study designed a science inquiry learning model, predict-observe-explain (POE), and implemented it in an app called "WhyWhy" to examine the effectiveness of students' science inquiry learning practice. To understand how POE can affect the cognitive-affective learning process, as well as the learning progress, a pretest and a posttest were given to 152 grade 5 elementary school students. The students practiced WhyWhy during six sessions over 6 weeks, and data related to interest in learning science (ILS), cognitive anxiety (CA), and extraneous cognitive load (ECL) were collected and analyzed through confirmatory factor analysis with structure equation modeling. The results showed that students with high ILS have low CA and ECL. In addition, the results also indicated that students with a high level of self-confidence enhancement showed significant improvement in the posttest. The implications of this study suggest that by using technology-enhanced science learning, the POE model is a practical approach to motivate students to learn.

    Aso, Eze

    A lack of research exists about how secondary school science teachers use inquiry-based instruction to improve student learning. The purpose of this qualitative study was to explore how science teachers used inquiry-based instruction to improve student learning in high school biology courses. The conceptual framework was based on Banchi and Bell's model of increasing levels of complexity for inquiry-based instruction. A multiple case study research design was conducted of biology programs at 3 high schools in an urban school district in the northeastern region of the United States. Participants included 2 biology teachers from each of the 3 high schools. Data were collected from individual interviews with biology teachers, observations of lessons in biology, and documents related to state standards, assessments, and professional development. The first level of data analysis involved coding and categorizing the interview and observation data. A content analysis was used for the documents. The second level of data analysis involved examining data across all sources and all cases for themes and discrepancies. According to study findings, biology teachers used confirmation, structure, and guided inquiry to improve student learning. However, they found open inquiry challenging and frustrating to implement because professional development about scaffolding of instruction over time was needed, and students' reading and writing skills needed to improve. This study contributes to positive social change by providing educators and researchers with a deeper understanding about how to scaffold levels of inquiry-based science instruction in order to help students become scientifically literate citizens.

    At present a lot of ideas for student inquiry-based activities accompanied with methodical remarks and instructions for teachers exist and can be used at physics lessons at lower and upper secondary levels. A need of the use of the teaching methods that support an independent student work as well as active learning approaches has been reflected also in the Slovak state educational program at various educational levels. Experiences of teachers who have used inquiry-based approaches in the classrooms are often in the contrary with expectations of these didactical trends. The paper aims to compare the theory and the practice of the implementation of inquiry-based activities in physics teaching. Practical experience was gained implementing activities for science education developed within the Chain Reaction project running at Matej Bel University Banska Bystrica. Opinions of teachers were investigated with the help of questionnaires, evaluation meetings and structured interviews. Their analysis identified many problems that the teachers had met during the implementation of the inquiry-based approaches in their teaching, as well as benefits of those activities for development of student competences.

    For science learning to be successful, students must develop attitudes toward support future engagement with challenging social issues related to science. This is especially important for increasing participation of students from underrepresented populations. This study investigated how participation in inquiry-based biology laboratory classes affected students' attitudes toward science, focusing on deaf, hard-of-hearing, and hearing signing students in bilingual learning environments (i.e., taught in American Sign Language and English). Analysis of reflection assignments and interviews revealed that the majority of students developed positive attitudes toward science and scientific attitudes after participating in inquiry-based biology laboratory classes. Attitudinal growth appears to be driven by student value of laboratory activities, repeated direct engagement with scientific inquiry, and peer collaboration. Students perceived that hands-on experimentation involving peer collaboration and a positive, welcoming learning environment were key features of inquiry-based laboratories, affording attitudinal growth. Students who did not perceive biology as useful for their majors, careers, or lives did not develop positive attitudes. Students highlighted the importance of the climate of the learning environment for encouraging student contribution and noted both the benefits and pitfalls of teamwork. Informed by students' characterizations of their learning experiences, recommendations are made for inquiry-based learning in college biology.

Students discover areas where the greatest damage occurred during the 1886 earthquake via a walking tour of Charleston. Extracting information from historical and topographic maps, and aerial and satellite imagery provides students with the necessary information to produce an earthquake hazard map of the area. Applying the creativity and knowledge base of the multidisciplinary students generates a startling array of innovative methods for communicating their results: brochures, storybooks, computer-animated hazard maps, Facebook pages, YouTube videos - even Virtual Reality avatars! When allowed to use their imaginations and resourcefulness, these students have no bounds! Not only does the application of inquiry-based problem solving methodology in conjunction with cooperative learning enhance comprehension of the material, but by allowing undergraduate students to develop methods of communicating their knowledge to the public through an interesting variety of medium, students remain focused, engaged, and even excited about learning science that otherwise intimidated them.

    Rogers, Jessica

    This paper describes a process that attempted to meet the needs of undergraduate students in a pre-nursing chemistry class. The laboratory was taught in traditional verification style and students were surveyed to assess their perceptions of the educational goals of the laboratory. A literature review resulted in an inquiry based method and analysis of the needs of nurses resulted in more application based activities. This new inquiry format was implemented the next semester, the students were surveyed at the end of the semester and results were compared to the previous method. Student and instructor response to the change in format was positive. Students in the traditional format placed goals concerning technique above critical thinking and felt the lab was easy to understand and carry out. Students in the inquiry based lab felt they learned more critical thinking skills and enjoyed the independence of designing experiments and answering their own questions.

    The purpose of this study was to examine instructional experiences of students with visual impairment in an guided inquiry-based science classroom. Drawing from social constructive perspectives about teaching and learning, I focused on the initial attempts of students to participate fully in an inquiry-based astronomy unit. The astronomy unit incorporated features of project-based science inquiry and aligned with national standards. This study described the opportunities provided to and challenges faced by students with visual impairment as they participated in the guided inquiry-based learning environment. Additionally, discursive practices of students including student-generated questions, student discussions, and students' science notebook writing were examined. Also, students' alternative conceptions about scientific phenomena and changes in students' thinking during the course of instruction, if any, were described. Methods of data collection included classroom observations, video records, pre- and post-curriculum assessments, attitudes toward science measurement, student interviews, and student artifacts (i.e., science notebook entries, student-constructed models). Findings showed that student learning was enhanced when the instructor-researcher guided students in accomplishing inquiry tasks and in making sense of their inquiry experiences. Additionally, the use of appropriate reflective prompts assisted students with visual impairment to fully participate in the writing tasks of the inquiry-based learning environment. Results suggested that the quantity and quality of student-generated questions increased with extended inquiry instruction. Also, students used questions to not only establish verbal communication, but to elaborate on their own thinking and expand or explain the thinking of others. Findings suggested also that students with visual impairment have similar alternative frameworks about scientific phenomena (i.e., causes of lunar phases, reason for

    Full Text Available Abstract: This study aims at investigating the effectiveness of the PQRST strategy in students’ reading comprehension, the effectiveness of the PQRST strategy in reading comprehension of students with different learning styles, and the interaction between the PQRST strategy and the students’ learning styles. This study employed a 2x2 factorial design. The subjects were the second semester students of Public Administration Department, Faculty of Political and Social Science, University of Bondowoso. Two classes were randomly selected as the samples of this study. The experimental class was taught by using the PQRST strategy and the non-experimental class by translation and reading aloud. The data were analysed by utilizing non parametric testing: Mann–Whitney U and Kruskall-Wallis. The findings showed that the PQRST strategy statistically impacted students’ reading comprehension compared to the one taught using the translation and reading aloud. But, it was revealed that there was no difference in the reading comprehension of students with different learning styles taught under the PQRST strategy and translation and reading aloud, and there was no interaction between teaching strategies and students’ learning styles.   Keywords: PQRST, learning styles, reading comprehension

    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.

  3. Inquiry-Based Instruction and High Stakes Testing

    Science.gov (United States)

    Cothern, Rebecca L.

    Science education is a key to economic success for a country in terms of promoting advances in national industry and technology and maximizing competitive advantage in a global marketplace. The December 2010 Program for International Student Assessment (PISA) ranked the United States 23rd of 65 countries in science. That dismal standing in science proficiency impedes the ability of American school graduates to compete in the global market place. Furthermore, the implementation of high stakes testing in science mandated by the 2007 No Child Left Behind (NCLB) Act has created an additional need for educators to find effective science pedagogy. Research has shown that inquiry-based science instruction is one of the predominant science instructional methods. Inquiry-based instruction is a multifaceted teaching method with its theoretical foundation in constructivism. A correlational survey research design was used to determine the relationship between levels of inquiry-based science instruction and student performance on a standardized state science test. A self-report survey, using a Likert-type scale, was completed by 26 fifth grade teachers. Participants' responses were analyzed and grouped as high, medium, or low level inquiry instruction. The unit of analysis for the achievement variable was the student scale score average from the state science test. Spearman's Rho correlation data showed a positive relationship between the level of inquiry-based instruction and student achievement on the state assessment. The findings can assist teachers and administrators by providing additional research on the benefits of the inquiry-based instructional method. Implications for positive social change include increases in student proficiency and decision-making skills related to science policy issues which can help make them more competitive in the global marketplace.

  6. Overcoming the difficulties of inquiry-based teaching through the use of coaching

    Science.gov (United States)

    Kraus, Rudolf

    This research examines the use of coaching as a professional development approach to enhance the introduction of inquiry-based teaching methods. Previous professional development efforts are well documented in the science education literature, and implementation rates are generally low, despite a wide-spread belief that inquiry-based teaching methods are beneficial to student learning. Difficulties that are often found include a lack of time, tension from high-stakes testing, a lack of content knowledge, a lack of inquiry knowledge, a scarcity of inquiry resources, and a conflict between the teacher's learning style and the inherent style of inquiry. These barriers lead to slow, poorly understood progress in adopting inquiry methods, and a shortage of concrete suggestions on how best to proceed. To examine how teacher-coach pairs overcome these difficulties, a multiple-case study was planned that uncovered specific steps taken by creating a richly detailed narrative of how this science curriculum is implemented. This narrative was closely affiliated with a certain specific context of underperforming high schools in a major American city, but the results may generalize to other similar contexts as well. Additionally, the findings from these case studies may serve to validate other analogous findings from the literature.

  7. Using inquiry-based instructional strategies in third-grade science

    Harris, Fanicia D.

    The purpose of the study was to determine if the use of inquiry-based instructional strategies as compared to traditional instructional strategies would increase third-grade students' achievement in science, based on the pretest/posttest of the school system and the Georgia Criterion-Referenced Competency Test (CRCT). Inquiry-based instruction, presented students with a question, an observation, a data set, or a hypothesis for problem solving such as scientists use when working in real-world situations. This descriptive research employed a quantitative strategy using a pretest/posttest control group design. The research compared the science academic achievement levels of one Grade 3 class [N=14] exposed to a teacher's inquiry-based instructional strategies as compared to one Grade 3 class [ N=18] exposed to a teacher's traditional instructional strategies. The study compared the science academic performance levels of third-grade students as measured by pretest/posttest mean scores from the school system-based assessment and the Georgia CRCT. Four research hypotheses were examined. Based on the overall findings from this study, both the experimental group and the control group significantly increased their mean scores from the pretests to the posttests. The amount of gain from the pretest to the posttest was significantly greater for the experimental group than the control group for pretest/posttest 1 [t(12) = 8.79, p learning strategies, given that the experimental group outperformed the control group on all four posttests, on the science CRCT and on the individual Science portions on the test including earth, life and physical sciences. In fact, this study was able to detect significant differences between the experimental group and the control group with regard to the degree to which the students improved from the pretests to the posttests.

  8. Sustaining inquiry-based teaching methods in the middle school science classroom

    Murphy, Amy Fowler

    This dissertation used a combination of case study and phenomenological research methods to investigate how individual teachers of middle school science in the Alabama Math, Science, and Technology Initiative (AMSTI) program sustain their use of inquiry-based methods of teaching and learning. While the overall context for the cases was the AMSTI program, each of the four teacher participants in this study had a unique, individual context as well. The researcher collected data through a series of interviews, multiple-day observations, and curricular materials. The interview data was analyzed to develop a textural, structural, and composite description of the phenomenon. The Reformed Teaching Observation Protocol (RTOP) was used along with the Assesing Inquiry Potential (AIP) questionnaire to determine the level of inquiry-based instruction occuring in the participants classrooms. Analysis of the RTOP data and AIP data indicated all of the participants utilized inquiry-based methods in their classrooms during their observed lessons. The AIP data also indicated the level of inquiry in the AMSTI curricular materials utilized by the participants during the observations was structured inquiry. The findings from the interview data suggested the ability of the participants to sustain their use of structured inquiry was influenced by their experiences with, beliefs about, and understandings of inquiry. This study contributed to the literature by supporting existing studies regarding the influence of teachers' experiences, beliefs, and understandings of inquiry on their classroom practices. The inquiry approach stressed in current reforms in science education targets content knowledge, skills, and processes needed in a future scientifically literate citizenry.

    Full Text Available Although there is a wide variety of perspectives and models for the study of online education, most of these focus on the analysis of the verbal aspects of such learning, while very few consider the relationship between speech and elements of a different nature, such as images and hypermediality. In a previous article we presented a proposal for a comprehensive semiotic analysis of virtual learning environments that more recently has been developed and tested for the study of different online training courses without instructional intervention. In this paper we use this same proposal to analyze online learning environments in the framework of courses with instructional intervention. One of the main observations in relation to this type of analyses is that the organizational aspects of the courses are found to be related to the way in which the input elements for the teaching and learning process are constructed.

  10. Comprehension evaluation and regulation in learning from science texts

    Science.gov (United States)

    Otero, Jose C.; Campanario, Juan M.

    Metacognitive variables influence students' learning from science texts. This article deals with the comprehension monitoring abilities of secondary school science students, one of the areas of metacognition which has drawn considerable attention from researchers. The aims of the study are, in particular: (a) to know the extent to which comprehension is monitored by secondary science students as revealed by inconsistency detection in manipulated science texts, and (b) to identify the strategies used to regulate comprehension by the students who detect the inconsistencies. The results indicate that knowing that one understands or fails to understand science texts could be as important a problem as understanding proper. Besides, some incorrect regulatory strategies used by students who notice the inconsistencies in the texts are identified. These could also have an annoying influence in the regulatory behavior of students when studying regular science texts.

    Full Text Available The main aim of the article is to show the connection between the comprehension and application of learning strategies in self-regulated learning in elementary school students. We would also like to show the connection between the comprehension and application of learning strategies and age, sex and school efficiency. The theoretical framework for the research is the four component model of self-regulative learning by B. Hofer, S. Yu and Pintrich (1998. We have focused on the first part of the model, which is about cognitive structure and cognitive strategies. The results of our research show that fifthgraderes use cognitive strategies before reading more often than seventhgraders. Girls use learning strategies more often than boys, particularly the strategies between and after reading. There are no significant differences in application of learning strategies between pupils with different school achievement. On the basis of the results of this research we also discuss possible educational implications.

  12. Do science coaches promote inquiry-based instruction in the elementary science classroom?

    Science.gov (United States)

    Wicker, Rosemary Knight

    The South Carolina Mathematics and Science Coaching Initiative established a school-based science coaching model that was effective in improving instruction by increasing the level of inquiry-based instruction in elementary science classrooms. Classroom learning environment data from both teacher groups indicated considerable differences in the quality of inquiry instruction for those classrooms of teachers supported by a science coach. All essential features of inquiry were demonstrated more frequently and at a higher level of open-ended inquiry in classrooms with the support of a science coach than were demonstrated in classrooms without a science coach. However, from teacher observations and interviews, it was determined that elementary schoolteacher practice of having students evaluate conclusions and connect them to current scientific knowledge was often neglected. Teachers with support of a science coach reported changes in inquiry-based instruction that were statistically significant. This mixed ethnographic study also suggested that the Mathematics and Science Coaching Initiative Theory of Action for Instructional Improvement was an effective model when examining the work of science coaches. All components of effective school infrastructure were positively impacted by a variety of science coaching strategies intended to promote inquiry. Professional development for competent teachers, implementation of researched-based curriculum, and instructional materials support were areas highly impacted by the work of science coaches.

    The need to prepare students with twenty-first-century skills through STEM-related teaching is strong, especially at the elementary level. However, most teacher education preparation programs do not focus on STEM education. In an attempt to provide an exemplary model of a STEM unit, we used a rapid prototyping approach to transform an inquiry-based unit on moon phases into one that integrated technology in a meaningful manner to develop technological literacy and scientific concepts for pre-service teachers (PSTs). Using qualitative case study methodology, we describe lessons learned related to the development and implementation of a STEM unit in an undergraduate elementary methods course, focusing on the impact the inquiry model had on PSTs' perceptions of inquiry-based science instruction and how the integration of technology impacted their learning experience. Using field notes and survey data, we uncovered three overarching themes. First, we found that PSTs held absolutist beliefs and had a need for instruction on inquiry-based learning and teaching. Second, we determined that explicit examples of effective and ineffective technology use are needed to help PSTs develop an understanding of meaningful technology integration. Finally, the rapid prototyping approach resulted in a successful modification of the unit, but caused the usability of our digital instructional materials to suffer. Our findings suggest that while inquiry-based STEM units can be implemented in existing programs, creating and testing these prototypes requires significant effort to meet PSTs' learning needs, and that iterating designs is essential to successful implementation.

    2015-01-01

    Undergraduate biochemistry laboratory courses often do not provide students with an authentic research experience, particularly when the express purpose of the laboratory is purely instructional. However, an instructional laboratory course that is inquiry- and research-based could simultaneously impart scientific knowledge and foster a student's research expertise and confidence. We have developed a year-long undergraduate biochemistry laboratory curriculum wherein students determine, via experiment and computation, the function of a protein of known three-dimensional structure. The first half of the course is inquiry-based and modular in design; students learn general biochemical techniques while gaining preparation for research experiments in the second semester. Having learned standard biochemical methods in the first semester, students independently pursue their own (original) research projects in the second semester. This new curriculum has yielded an improvement in student performance and confidence as ...

  17. Middle school students' development of inscriptional practices in inquiry-based science classrooms

    Science.gov (United States)

    Wu, Hsin-Kai

    The purpose of this study is to characterize the learning practices demonstrated by seventh graders when they used various scientific inscriptions in an inquiry-based learning environment. Inscriptions are types of transformations, such as graphs, diagrams, data tables, symbols, maps, and models, that materialize or visualize an entity into another format or mode. As suggested by science studies, scientific knowledge and the reality of science are constructed through manipulating a variety of inscriptions. However, little is known about how middle school students make use of inscriptions over time and what resources or features of the learning environment support students in doing so. Drawing on a naturalistic approach, this classroom-based study aims to characterize students' inscriptional practices, trace their learning trajectories, examine potential use of various scientific inscriptions, and analyze the learning supports and resources provided by the teachers and the learning environment. This eight-month study is conducted in two inquiry-based science classes with participation of two teachers and 27 seventh graders. Two student dyads from each class were observed intensively. Multiple sources of data were collected, including fieldnotes, classroom video recordings, process video recordings, computer-based models, webpages, science reports, notebooks, and transcripts from interviews with students and teachers. Several analytical steps were taken to analyze and synthesize these data. Expanding upon early research on students' learning of inscriptions, this study shows that seventh graders could demonstrate competent, purposeful inscriptional practices when they were scaffolded by the teachers and the curriculum in a learning environment where the inscriptional activities were sequenced, iterated, and embedded in scientific inquiry. Additionally, using inscriptions in science classrooms provided students with opportunities to engage in thoughtful discussions

  20. "Kindergarten, can I have your eyes and ears?" politeness and teacher directive choices in inquiry-based science classrooms

    Science.gov (United States)

    Oliveira, Alandeom Wanderlei

    2009-12-01

    This study explores elementary teachers' social understandings and employment of directives and politeness while facilitating inquiry science lessons prior and subsequent to their participation in a summer institute in which they were introduced to the scholarly literature on regulative discourse (directives used by teachers to regulate student behavior). A grounded theory analysis of the institute professional development activities revealed that teachers developed an increased awareness of the authoritative functions served by impolite or direct directives (i.e., pragmatic awareness). Furthermore, a comparative microethnographic analysis of participants' inquiry-based classroom practices revealed that after the institute teachers demonstrated an increased ability to share authority with students by strategically making directive choices that were more polite, indirect, inclusive, involvement-focused and creative. Such ability led to a reduced emphasis on teacher regulation of student compliance with classroom behavioral norms and an increased focus on the discursive organization of the inquiry-based science learning/teaching process. Despite teachers' increased pragmatic awareness, teacher-student linguistic relationships did not become entirely symmetrical subsequent to their participation in the summer institute (i.e., teacher authority was not completely relinquished or lost). Based on such findings, it is argued that teachers need to develop higher levels of pragmatic awareness to become effectively prepared to engage in language-mediated teacher-student interaction in the context of inquiry-based science classroom discourse.

    The Centre for Planetary Science and Exploration (CPSX - http://cpsx.uwo.ca) at The University of Western Ontario has initiated a comprehensive outreach and education program focusing on planetary science and exploration. The goal is to use planetary science to raise general interest in science. Currently, the activities being preformed by the centre can be divided into three broad categories: (1) educational/curriculum based activities, (2) outreach/community based activities, and (3) training. The first is where the push for an increase in interest for science is really critical and is the focus here. In partnership with the Thames Valley District School Board and by using inquiry-based teaching methods, students study various topics under the guidance of a CPSX graduate students and faculty. The educational activities that have taken place are all based on the Ontario curriculum and have been developed with the support of the local school board and teachers. An annual teacher workshop provides a hands-on opportunity for the teachers to interact with CPSX members. The first activity to be developed was on meteorite impact craters. The CPSX web page also contains the lesson plans and activity work sheets for this Cratering Activity, as well as additional activities. As the Cratering Activity is available online, teachers can perform the experiment independently or request the support from a CPSX outreach member. The activity is designed with the following structure: (1) The teacher gives a background presentation (provided by CPSX) which describes crater processes throughout our solar system (specifically comparing Earth to other planets), the consequences of impacts on Earth, the origins of impactors (small bodies) in our solar system, and the mechanical process of an impact. (2) The teacher demonstrates an impact event. Students are to make observations in their lab handout, and sketch what they see. (3) Students (either individually or as a group, based on

  3. Comprehension of humor in children with nonverbal learning disabilities, reading disabilities, and without learning disabilities.

    Semrud-Clikeman, Margaret; Glass, Kimberly

    2008-12-01

    The normal development of humor in children has been well documented with a predictable course that is tied to social, cognitive, and linguistic development in children. This study explored humor comprehension in children with nonverbal learning disabilities (NVLD). Children with NVLD were compared with children with reading disabilities and a comparison group of children with no learning disabilities to assess their comprehension of humor. The humor test was composed of a joke and cartoon section. No group differences in humor comprehension were found when the NVLD group was defined as having visual-spatial and visual reasoning deficits. However, when the NVLD group was divided into children with and without social perceptual difficulties as defined by a direct measure of social comprehension, significant group differences were found in the levels of humor comprehension. These results support the association of humor comprehension with social perception and lend tentative support to the hypothesis that children with NVLD may not be a homogenous group. Future study directions include further exploration into the nature of the association between humor comprehension and social perception as well as closer examination of the heterogeneity of NVLD.

    2013-03-01

    High school students in the United States are apathetic about science, technology, engineering and mathematics (STEM), and the workforce pipeline in these areas is collapsing. The lack of understanding of basic principles of biology means that students are unable to make educated decisions concerning their personal health. To address these issues, we have developed a simple, inquiry-based outreach lesson centered on a mouse dissection. Students learn key concepts in immunology and enhance their understanding of human organ systems. The experiment highlights aspects of the scientific method and authentic data collection and analysis. This hands-on activity stimulates interest in biology, personal health and careers in STEM fields. Here, we present all the information necessary to execute the lesson effectively with middle and high school students.

    D'Angelo, Heather Hopkins

    This research utilized inquiry based science as a vehicle to implement and maintain social skills training for secondary students, ages 14 to 20, with low-incidence disabilities in a self-contained classroom. This three year action research study examined the effects of an inquiry based science curriculum on the level and quantity of social skills used by students with one or more of the following challenges: significant learning disability (functioning more than two grade levels below grade level), emotional/social disability, mental retardation, Autism, and/or varying degrees of brain damage. Through the use of video recording, the students in the study were analyzed based on the level of social interaction and the amount of socialization that took place during inquiry based science. The skills sought were based on the social and communication skills earmarked in the students' weekly social skills training class and their Individualized Education Plans (IEP). Based on previous research in social skills training it has been determined that where social skills training is lacking are in the areas of transfer and maintenance of skills. Due to the natural social behavior that must take place in inquiry based science this group of students were found to exhibit gains in (1) quantity of social interactions on topic; (2) developing higher levels of social interactions (sharing, taking other's suggestions, listening and responding appropriately, etc.); and (3) maintenance of social skills taught outside of formal social skills training. These gains were seen overall in the amount of student involvement during inquiry based science verses teacher involvement. Such increases are depicted through students' verbal exchanges, excerpts from field notes, and student reflections. The findings of this research is expected to guide special educators, administrators and directors of curriculum as to how to better create curriculum for this specific population where social skills

  9. Guided-inquiry based laboratory instruction: Investigation of critical thinking skills, problem solving skills, and implementing student roles in chemistry

    Science.gov (United States)

    Gupta, Tanya

    Recent initiatives in the laboratory curriculum have encouraged an inquiry-based approach to learning and teaching in the laboratory. It has been argued that laboratory instruction should not just be hands-on, but it should portray the essence of inquiry through the process of experiential learning and reflective engagement in collaboration with peers and in facilitation by the instructor. A student-centered active learning approach may be an effective way to enhance student understanding of concepts in the laboratory. The dissertation research work explores the impact of laboratory instruction and its relevance for college-level chemistry. Each chapter is different from the preceding chapter in terms of the purpose of the study and the research questions asked. However, the overarching idea is to address the importance of guided-inquiry based laboratory instruction in chemistry and its relevance in helping students to make connections with the chemistry content and in imparting skills to students. Such skills include problem solving, collaborative group work and critical thinking. The first research study (Chapter 2) concerns the impact of first year co-requisite general chemistry laboratory instruction on the problem-solving skills of students. The second research study (Chapter 3) examines the impact of implementing student roles also known as Student-Led Instructor Facilitated Guided-Inquiry based Laboratories, SLIFGIL) by modifying the Science Writing Heuristic approach of laboratory instruction. In the third research study (Chapter 4), critical thinking skills of first semester general chemistry laboratory students were compared to advanced (third or fourth year) chemistry laboratory students based on the analysis of their laboratory reports.

    Foster, Hyacinth Carmen

    Science educators and administrators support the idea that inquiry-based and didactic-based instructional strategies have varying effects on students' acquisition of science concepts. The research problem addressed whether incorporating the two approaches covered the learning requirements of all students in science classes, enabling them to meet state and national standards. The purpose of this quasiexperimental, posttest design research study was to determine if student learning and achievement in high school biology classes differed for each type of instructional method. Constructivism theory suggested that each learner creates knowledge over time because of the learners' interactions with the environment. The optimal teaching method, didactic (teacher-directed), inquiry-based, or a combination of two approaches instructional method, becomes essential if students are to discover ways to learn information. The research question examined which form of instruction had a significant effect on student achievement in biology. The data analysis consisted of single-factor, independent-measures analysis of variance (ANOVA) that tested the hypotheses of the research study. Locally, the results indicated greater and statistically significant differences in standardized laboratory scores for students who were taught using the combination of two approaches. Based on these results, biology instructors will gain new insights into ways of improving the instructional process. Social change may occur as the science curriculum leadership applies the combination of two instructional approaches to improve acquisition of science concepts by biology students.

    Demir, Abdulkadir

    The purpose of this phenomenographic study was to: (a) understand how beginning science teachers recruited from various science disciplines and prepared in an Alternative Teacher Certification Program (ATCP) implemented inquiry during their initial years of teaching; (b) describe constraints and needs that these beginning science teachers perceived in implementing inquiry-based science instruction; and (c) understand the relation between what they learned in their ATCP and their practice of teaching science through inquiry. The participants of this study consisted of four ATCP teachers who are in their beginning years of teaching. Semi-structured interviews, classroom observation, field notes, and artifacts used as source of data collection. The beginning science teachers in this study held incomplete views of inquiry. These views of inquiry did not reflect inquiry as described in NRC (2000)---essential features of inquiry,---nor did they reflect views of faculty members involved in teaching science methods courses. Although the participants described themselves as reform-oriented, there were inconsistencies between their views and practices. Their practice of inquiry did not reflect inquiry either as outlined by essential features of inquiry (NRC, 2000) or inquiry as modeled in activities used in their ATCP. The research participants' perceived constraints and needs in their implementation of inquiry-based activities. Their perceived constraints included logistical and student constraints and school culture. The perceived needs included classroom management, pedagogical skills, practical knowledge, discipline, successful grade-specific models of inquiry, and access to a strong support system. Prior professional work experience, models and activities used in the ATCP, and benefits of inquiry to student learning were the declared factors that facilitated the research participants' practice of inquiry-based teaching.

    The University of South Florida, College of Marine Science Oceans: GK-12 Teaching Fellowship Program is successfully enriching science learning via the oceans. Funded by the National Science Foundation, the program provides a unique opportunity among scientists and K-12 teachers to interact with the intention of bringing ocean science concepts and research to the classroom environment enhance the experience of learning and doing science, and to promote `citizen scientists' for the 21st century. The success of the program relies heavily on the extensive summer training program where graduate students develop teaching skills, create inquiry based science activities for a summer Oceanography Camp for Girls program and build a relationship with their mentor teacher. For the last year and a half, two graduate students from the College of Marine Science have worked in cooperation with teachers from the Pinellas county School District, Southside Fundamental Middle School. Successful lesson plans brought into a 6th grade Earth Science classroom include Weather and climate: Global warming, The Geologic timescale: It's all about time, Density: Layering liquids, and Erosion processes: What moves water and sediment. The school and students have benefited greatly from the program experiencing hands-on inquiry based science and the establishment of an after school science club providing opportunities for students to work on their science fair projects and pursuit other science interests. Students are provided scoring rubrics and their progress is creatively assessed through KWL worksheets, concept maps, surveys, oral one on one and classroom discussions and writing samples. The year culminated with a series of hands on lessons at the nearby beach, where students demonstrated their mastery of skills through practical application. Benefits to the graduate student include improved communication of current science research to a diverse audience, a better understanding of the

  20. The experiences of science teachers' particpation in an inquiry-based professional development

    Jackson, Emily A.

    Once a leader in science, technology, engineering, and mathematics (STEM) education, the United States (U.S.) is now far behind many countries. There is growing concern that the U.S. is not preparing a sufficient number of students in the areas of STEM. Despite advancement of inquiry learning in science, the extent to which inquiry learning has been implemented on a classroom level falls short. The purpose of this study was to learn about the experiences of science teachers' participation in an inquiry-based professional development. A mixed method research design was used for this study to collect data from ten Project MISE participants. The qualitative data was collected using semi-structured, in-depth individual interviews, focus group interviews, observations, and document analysis of teacher portfolios and analyzed using constant comparative method. The quantitative data were collected through administration of a pretest and posttest instrument that measures the content knowledge of the science teachers and analyzed using descriptive statistics and paired t-test. The participants of this mixed methods study provided compelling evidence that Project MISE has a profound impact on their instructional practice, networking abilities, opportunities for reflection, and content knowledge.

    In this NSF-funded project we will adapt problem-based learning (PBL) and other inquiry-based approaches to create an integrated science and education methods curriculum ("science semester") for elementary teacher education majors. Our goal is to foster integrated understandings of science and pedagogy that future elementary teachers need to effectively use inquiry-based approaches in their classrooms. This project responds to calls to improve science education for all students by making preservice teachers' experiences in undergraduate science courses more consistent with reforms at the K-12 level. The involved faculty teach three science courses (biology, earth science, physical science) and an elementary science education methods course that are degree requirements for elementary teacher education majors. Presently, students take the courses in variable sequences and at widely scattered times. Too many students fail to appreciate the value of science courses to their future careers as teachers, and when they reach the methods course in the junior year they often retain little of the science content studied earlier. These episodic encounters with science make it difficult for students to learn the content, and to translate their understandings of science into effective, inquiry-based teaching strategies. To encourage integrated understandings of science concepts and pedagogy we will coordinate the science and methods courses in a junior-year science semester. Traditional subject matter boundaries will be crossed to stress shared themes that teachers must understand to teach standards-based elementary science. We will adapt exemplary approaches that support both learning science and learning how to teach science. Students will work collaboratively on multidisciplinary PBL activities that place science concepts in authentic contexts and build learning skills. "Lecture" meetings will be large group active learning sessions that help students understand difficult

    Undergraduate biochemistry laboratory courses often do not provide students with an authentic research experience, particularly when the express purpose of the laboratory is purely instructional. However, an instructional laboratory course that is inquiry- and research-based could simultaneously impart scientific knowledge and foster a student's research expertise and confidence. We have developed a year-long undergraduate biochemistry laboratory curriculum wherein students determine, via experiment and computation, the function of a protein of known three-dimensional structure. The first half of the course is inquiry-based and modular in design; students learn general biochemical techniques while gaining preparation for research experiments in the second semester. Having learned standard biochemical methods in the first semester, students independently pursue their own (original) research projects in the second semester. This new curriculum has yielded an improvement in student performance and confidence as assessed by various metrics. To disseminate teaching resources to students and instructors alike, a freely accessible Biochemistry Laboratory Education resource is available at http://biochemlab.org.

    Full Text Available In this study, the pedagogical content knowledge (PCK of four experienced primary school teachers was investigated within the “Let’s Solve the Riddle of Our Body Unit”. The PCK investigation adopted a learning approach based on inquiry, content representation and pedagogical and professional-experience repertoires (PaP-eRs, and interview forms were used as data collection tools. During the course of the research, the findings obtained from observations made during a total of 18 course hours formed the basic data source of the study. According to the results of the study, in which descriptive and content analysis were used concurrently, primary school teachers lack subject matter knowledge, do not interrogate the pre-knowledge of students and some misconceptions exist regarding about blood moves and exercise with pulse. Additionally, some deficiencies were detected in the curriculum, i.e., it offers non-inquisitional knowledge. Furthermore, teachers employee assessment methods with traditional teaching methods and techniques. In the context of an inquiry-based learning approach, teachers appeared to believe that classroom activities were adversely affected by the physical conditions (class size, lack of laboratory etc., students’ cognitive levels and parent profiles. The result of this study revealed that PCK components affect one another. The PCK findings pertaining to primary school teachers as it concerns the unit are briefly discussed and some suggestions about the development of PCK are submitted.

    Thoresen, Carol Wiggins

    1994-01-01

    This study determined if the training provided physics teaching assistants was sufficient to accomplish the objectives of inquiry-based tutorials for an introductory physics course. Qualitative research methods were used: (1) to determine if the Physics by Inquiry method was modeled; (2) to describe the process from the teaching assistant perspective; (3) to determine TA opinions on training methods; (4) to develop a frame of reference to better understand the role of TA's as instructional support staff. The study determined that the teaching assistants verbalized appropriate instructional actions, but were observed to use a predominantly didactic teaching style. TA's held a variety of perceptions and beliefs about inquiry -based learning and how science is learned. They felt comfortable in the role of tutorial instructor. They were satisfied with the training methods provided and had few suggestions to change or improve training for future tutorial instructors. A concurrent theme of teacher action dependent on teacher beliefs was sustained throughout the study. The TA's actions, as tutorial instructors, reflected their educational beliefs, student background and learning experiences. TA's performance as tutorial instructors depended on what they think and believe about learning science. Practical implications exist for training teaching assistants to be tutorial instructors. Some recommendations may be appropriate for TA's required to use instructional methods that they have not experienced as students. Interview prospective teaching assistants to determine educational experience and beliefs. Employ inexperienced teaching assistants whose perspectives match the proposed instructional role and who might be more receptive to modeling. Incorporate training into staff meetings. Provide time for TA's to experience the instructional model with simulation or role play as students and as instructors, accompanied by conference discussion. Use strategies known to enhance

  9. A well-started beginning elementary teacher's beliefs and practices in relation to reform recommendations about inquiry-based science

    2016-03-01

    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.

  10. Graduate Student and High School Teacher Partnerships Implementing Inquiry-Based Lessons in Earth Science

    Partnering science graduate students with high school teachers in their classroom is a mutually beneficial relationship. Graduate students who may become future university level faculty are exposed to teaching, classroom management, outreach scholarship, and managing time between teaching and research. Teachers benefit by having ready access to knowledgeable scientists, a link to university resources, and an additional adult in the classroom. Partnerships in Research Opportunities to Benefit Education (PROBE), a recent NSF funded GK-12 initiative, formed partnerships between science and math graduate students from the University of New Hampshire (UNH) and local high school science teachers. A primary goal of this program was to promote inquiry-based science lessons. The teacher-graduate student teams worked together approximately twenty hours per week on researching, preparing, and implementing new lessons and supervising student-led projects. Several new inquiry-based activities in Geology and Astronomy were developed as a result of collaboration between an Earth Science graduate student and high school teacher. For example, a "fishbowl" activity was very successful in sparking a classroom discussion about how minerals are used in industrial materials. The class then went on to research how to make their own paint using minerals. This activity provided a capstone project at the end of the unit about minerals, and made real world connections to the subject. A more involved geology lesson was developed focusing on the currently popular interest in forensics. Students were assigned with researching how geology can play an important part in solving a crime. When they understood the role of geologic concepts within the scope of the forensic world, they used techniques to solve their own "crime". Astronomy students were responsible for hosting and teaching middle school students about constellations, using a star- finder, and operating an interactive planetarium

  11. Preparing pre-service teachers to integrate technology into inquiry-based science education: Three case studies in The Netherlands

    2016-05-01

    Integration of technology ( e.g. measuring with sensors, video measurement, and modeling) into secondary-school science teaching is a need globally recognized. A central issue of incorporating these technologies in teaching is how to turn manipulations of equipment and software into manipulations of ideas. Therefore, preparation for pre-service teachers to apply ICT tools should be combined with the issues of minds-on inquiring and meaning-making. From this perspective, we developed a course within the post-graduate teacher-education program in the Netherlands. During the course, pre-service teachers learnt not only to master ICT skills but also to design, teach, and evaluate an inquiry-based lesson in which the ICT tool was integrated. Besides three life sessions, teachers' learning scenario also consisted of individual tasks which teachers could carry out mostly in the school or at home with support materials and online assistance. We taught three iterations of the course within a design-research framework in 2013, 2014 and collected data on the teacher learning processes and outcomes. The analyses of these data from observation, interviews, questionnaires, and documents were to evaluate implementation of the course, then suggest for revisions of the course set-up, which was executed and then assessed again in a subsequent case study. Main outcomes of the three case studies can be summarized as follows: within a limited time (3 life sessions spread over 2-3 months), the heterogeneous groups of pre-service teachers achieved a reasonable level of competence regarding the use of ICT tools in inquiry-based lessons. The blended set-up with support materials, especially the Coach activities and the lesson-plan form for an ICT-integrated inquiry-based lesson, contributed to this result under the condition that the course participants really spent considerable time outside the life sessions. There was a need for more time for hands-on, in-group activities in life

  12. Investigating elementary education and physical therapy majors' perceptions of an inquiry-based physics content course

    Science.gov (United States)

    Hilton, John Martin

    This study investigates why physical therapy assistant majors engage and perform better than elementary education majors in an inquiry-based conceptual physics course at Mid-Atlantic Community College. The students from each major are demographically similar, both courses are similar in depth and structure, and each course supports the students' program. However, there is an observed difference in the levels of engagement with the curriculum and performance on writing-based assessments between the two groups. To explore possible explanations for the difference, I examine students' affinity for science, their beliefs about the nature of science and scientific knowledge in the classroom, and their perception of the usefulness of science to their program. During semi-structured interviews, students from both majors displayed nearly identical weak affinities for science, epistemological beliefs, and uncertainty about the usefulness of the class. However, the physical therapy majors' ability to see the relevance of the physics course experience to their program enhanced their interest and motivation. In contrast, the elementary education students do not see connections between the course and their program, and do not see a purpose for their learning of physics content. To improve the program, I propose a two-pronged approach - designing a faded-scaffolded-inquiry approach for both classes, and developing a field-based/seminar class for the elementary education majors. The scaffolded inquiry will help both groups develop better orientations toward lab activities, and the structured observations and reflection will help the elementary group connect the material to their program.

  13. Implementation of inquiry-based science education in different countries: some reflections

    Science.gov (United States)

    Rundgren, Carl-Johan

    2017-03-01

    In this forum article, I reflect on issues related to the implementation of inquiry-based science education (IBSE) in different countries. Regarding education within the European Union (EU), the Bologna system has in later years provided extended coordination and comparability at an organizational level. However, the possibility of the EU to influence the member countries regarding the actual teaching and learning in the classrooms is more limited. In later years, several EU-projects focusing on IBSE have been funded in order to make science education in Europe better, and more motivating for students. Highlighting what Heinz and her colleagues call the policy of `soft governance' of the EU regarding how to improve science education in Europe, I discuss the focus on IBSE in the seventh framework projects, and how it is possible to maintain more long-lasting results in schools through well-designed teacher professional development programs. Another aspect highlighted by Heinz and her colleagues is how global pressures on convergence in education interact with educational structures and traditions in the individual countries. The rise of science and science education as a global culture, encompassing contributions from all around the world, is a phenomenon of great potential and value to humankind. However, it is important to bear in mind that if science and science education is going to become a truly global culture, local variation and differences regarding foci and applications of science in different cultures must be acknowledged.

  17. An inquiry-based approach to the Franck-Hertz experiment

    Persano Adorno, Dominique; Pizzolato, Nicola

    2016-05-01

    The practice of scientists and engineers is today exerted within interdisciplinary contexts, placed at the intersections of different research fields, including nanoscale science. The development of the required competences is based on an effective science and engineering instruction, which should be able to drive the students towards a deeper understanding of quantum mechanics fundamental concepts and, at the same time, strengthen their reasoning skills and transversal abilities. In this study we report the results of an inquiry-driven learning path experienced by a sample of 12 electronic engineering undergraduates engaged to perform the Franck-Hertz experiment. Before being involved in this experimental activity, the students received a traditional lecture-based instruction on the fundamental concepts of quantum mechanics, but their answers to an open-ended questionnaire, administered at the beginning of the inquiry activity, demonstrated that the acquired knowledge was characterized by a strictly theoretical vision of quantum science, basically in terms of an artificial mathematical framework having very poor connections with the real world. The Franck Hertz experiment was introduced to the students by starting from the problem of finding an experimental confirmation of the Bohr's postulates asserting that atoms can absorb energy only in quantum portions. The whole activity has been videotaped and this allowed us to deeply analyse the student perception's change about the main concepts of quantum mechanics. We have found that the active participation to this learning experience favored the building of cognitive links among student theoretical perceptions of quantum mechanics and their vision of quantum phenomena, within an everyday context of knowledge. Furthermore, our findings confirm the benefits of integrating traditional lecture-based instruction on quantum mechanics with learning experiences driven by inquiry-based teaching strategies.

  18. Language exposure facilitates talker learning prior to language comprehension, even in adults.

    Orena, Adriel John; Theodore, Rachel M; Polka, Linda

    2015-10-01

    Adults show a native language advantage for talker identification, which has been interpreted as evidence that phonological knowledge mediates talker learning. However, infants also show a native language benefit for talker discrimination, suggesting that sensitivity to linguistic structure due to systematic language exposure promotes talker learning, even in the absence of functional phonological knowledge or language comprehension. We tested this hypothesis by comparing two groups of English-monolingual adults on their ability to learn English and French voices. One group resided in Montréal with regular exposure to spoken French; the other resided in Storrs, Connecticut and did not have French exposure. Montréal residents showed faster learning and better retention for the French voices compared to their Storrs-residing peers. These findings demonstrate that systematic exposure to a foreign language bolsters talker learning in that language, expanding the gradient effect of language experience on talker learning to perceptual learning that precedes sentence comprehension.

    Sumrall, Thomas Franklin

    The present study was designed to examine the relationship between the dependent variables of K-5 elementary teachers' attitudes toward inquiry-based science, implementation of National Science Education Standards concerning inquiry-based science, and the number of inquiry-based lessons taught with the predictor variables of gender, school district teaching, ethnic group, educational level, experience, grade level teaching, and number of science courses taken. Four hundred thirty teachers of grades K through 5 from seven school districts in south Mississippi were surveyed using the Revised Science Attitude Scale (Bitner, 1994), Inquiry Beliefs and Practices survey (Jeanpierre, 2006), and a demographic questionnaire. A total of 814 teachers were invited to participate in the study. Multiple linear regression techniques were used to test the hypotheses of this study at a .05 level. Results indicate that number of courses taken is a predictor for all subscales of attitude toward inquiry-based science. Grade level teaching was a significant predictor for two subscales of attitude and gender along with school district were predictors for one subscale for attitude. Results also indicate that school district, ethnic group, and grade level teaching are significant predictors of the complex skills subscale for implementation of inquiry-based lessons. The predictors of gender, school district, and number of courses taken were found to be significant concerning the number of inquiry-based lessons taught. Positive correlations were found between the four subscales for attitude, the two subscales for inquiry beliefs and practices, and the number of inquiry-based lessons taught. Conclusions, implications, and recommendations for future research are included.

    Full Text Available The main purpose of this design-based research study is to examine the effects of an inquiry-based learning environment, with the support of videoconferencing, on both rural and urban secondary students’ mathematics and science learning. An important aspect of this learning environment is the use of videoconferencing to connect classes with mathematicians/ scientists (as e-mentors. Specifically, the following two research questions guide this study: (1 In what ways, if any, does the inquiry-based learning environment impact student beliefs and learning outcomes? (2 What challenges emerge in the development of an inquiry-based learning environment with secondary students in both rural and urban schools? Using a mixed methods approach, this study focuses on two grade 9 classes in an urban school and three Grade 8 classes in a rural school. The results suggest positive effects of this learning environment on student learning of math and science. In particular, both urban and rural students showed significant gains in their achievement. In addition, students showed an increased interest and heightened confidence in math and science. As well, the results point to issues arising from the process, suggesting useful guidelines for the development of such environments.

    Evidence from numerous studies using the visual world paradigm has revealed both that spoken language can rapidly guide attention in a related visual scene and that scene information can immediately influence comprehension processes. These findings motivated the coordinated interplay account (Knoeferle & Crocker, 2006) of situated comprehension, which claims that utterance-mediated attention crucially underlies this closely coordinated interaction of language and scene processing. We present a recurrent sigma-pi neural network that models the rapid use of scene information, exploiting an utterance-mediated attentional mechanism that directly instantiates the CIA. The model is shown to achieve high levels of performance (both with and without scene contexts), while also exhibiting hallmark behaviors of situated comprehension, such as incremental processing, anticipation of appropriate role fillers, as well as the immediate use, and priority, of depicted event information through the coordinated use of utterance-mediated attention to the scene.

    Full Text Available Introduction: Acquisition of intelligible English pronunciation and comprehension of medical texts has been considered as an important need for medical students. This can be improved by employing different methods and taking into consideration various learning styles of students. This study is an attempt to reveal the effect of cooperative learning on enhancing pronunciation and reading comprehension in students of medicine in Yasuj University of Medical Sciences. Methods: All 60 students of medicine in Yasuj University of Medical Sciences who enrolled in English for specific purposes 1st Feb 2013 took part in this quasi experimental study and were divided into two groups of thirties, according to the enrollment list. Cooperative learning was implemented with the experimental group dividing them into groups of five randomly, while the control group was taught with traditional method. Phonetic transcriptions were used along with passages taken from their book for the two groups. The data collected from three reading aloud tasks, scores of pretest, and midterm and final written examinations were analyzed using SPSS software, version19. Results: The results of the study showed that the experimental group outperformed the control group significantly (P<0.05 in all areas of reading aloud tests, pronunciation, and comprehension. Conclusion: It is concluded that cooperative learning significantly improves medical students’ pronunciation and comprehension. Teaching pronunciation and comprehension through cooperative learning yields better learning results for university students.

  7. Determinants of Benin elementary school science teachers' orientation toward inquiry-based instructional practices

    Science.gov (United States)

    Gado, Issaou

    The Republic of Benin (West Africa) undertook a nationwide curriculum reform that put an emphasis on inquiry-based instructional practices. Little, if any, research has been conducted to explore factors that could be related to teachers' orientation toward inquiry instructional practices. The purpose of this research study was to investigate factors and concerns that determine Benin elementary school teachers' orientation toward the use of inquiry-based instruction in the teaching of science. The study followed a naturalistic inquiry methodology combining a correlational ex post facto design and an observational case-study design. The theory of Planned Behavior was the conceptual framework used to design the study. Two hundred (N = 200) elementary school teachers and three (n = 3) case study participants were purposively selected. Data was gathered via the Revised Science Attitude Scale (Thompson & Shrigley, 1986), the Science Teachers' Ideological Preference Scale (Jones & Harty, 1978), open-ended questions, interviews, and classroom observations using audiorecorders, videorecorders, and the researcher-contextualized version of the Observational System for the Analysis of Classroom Instruction (Hough, 1966). Qualitative and quantitative data provided a deeper understanding of participants' responses. Quantitative measures indicated that Benin elementary school teachers have positive attitudes toward school science, significant positive orientation toward both inquiry-based instruction and traditional non inquiry-based instruction, and higher orientation toward inquiry-based instruction than traditional non inquiry-based instruction. Attitude toward handling materials for investigations was found to significantly contribute to the prediction of participants' inquiry orientation. Qualitative analyses of participants' responses indicated that the expectations of educational leaders, individual motivation to comply with the program, a perceived control of the

    2007-01-01

    We discuss an inquiry-based curriculum that has been developed specifically for the introductory algebra-based physics course, taking into account the needs, backgrounds, learning styles and career goals of the students in that class. The course is designed to be taught in a laboratory-based environment, however parts of the materials can be used in other settings. As instructors we found ourselves drawing on materials developed for the calculus-based course and for other populations (materials developed for pre-service teachers, for example), parts of which were appropriate, but not a complete curriculum as we would like to teach it, developed specifically for students in the introductory algebra-based physics course. So we have modified and adapted parts of existing materials and integrated them with our own new units and our own format, creating a course aimed specifically at these students.

    Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence. This paper assesses the outcomes of a novel inquiry-based paleoanthropology lab teaching human evolution to high-school students. The inquiry-based Be a Paleoanthropologist for a Day lab placed a dozen hominin skulls into the hands of high-school students. Upon measuring three variables of human evolution, students explain what they have observed and discuss findings. In the 2013/14 school year, 11 biology classes in 7 schools in the Greater New Orleans area participated in this lab. The interviewed teacher cohort unanimously agreed that the lab featuring hominin skull replicas and stimulating student inquiry was a pedagogically excellent method of delivering the subject of human evolution. First, the lab's learning path of transforming facts to data, information to knowledge, and knowledge to acceptance empowered students to themselves execute part of the science that underpins our understanding of deep time hominin evolution. Second, although challenging, the hands-on format of the lab was accessible to high-school students, most of whom were readily able to engage the lab's scientific process. Third, the lab's exciting and compelling pedagogy unlocked higher order thinking skills, effectively activating the cognitive, psychomotor and affected learning domains as defined in Bloom's taxonomy. Lastly, the lab afforded students a formative experience with a high degree of retention and epistemic depth. Further study is warranted to gauge the degree of these effects.

    2014-08-01

    As teacher educators, we are tasked with preparing prospective teachers to enter a field that has undergone significant changes in student population and policy since we were K-12 teachers. With the emphasis placed on connections, mathematics integration, and communication by the New Generation Science Standards (NGSS) (Achieve in Next generation science standards, 2012), more research is needed on how teachers can accomplish this integration (Bunch in Rev Res Educ 37:298-341, 2013; Lee et al. in Educ Res 42(4):223-233, 2013). Science teacher educators, in response to the NGSS, recognize that it is necessary for pre-service and in-service teachers to know more about how instructional strategies in language and science can complement one another. Our purpose in this study was to explore a model of integration that can be used in classrooms. To do this, we examined the change in science content knowledge and academic vocabulary for English language learners (ELLs) as they engaged in inquiry-based science experience utilizing the 5R Instructional Model. Two units, erosion and wind turbines, were developed using the 5R Instructional Model and taught during two different years in a summer school program for ELLs. We analyzed data from interviews to assess change in conceptual understanding and science academic vocabulary over the 60 h of instruction. The statistics show a clear trend of growth supporting our claim that ELLs did construct more sophisticated understanding of the topics and use more language to communicate their knowledge. As science teacher educators seek ways to prepare elementary teachers to help preK-12 students to learn science and develop the language of science, the 5R Instructional Model is one pathway.

  15. How does participation in inquiry-based activities influence gifted students' higher order thinking?

    Science.gov (United States)

    Reger, Barbara H.

    Inquiry-based learning is considered a useful technique to strengthen the critical thinking skills of students. The National Science Standards emphasize its use and the complexities and challenge it provides are well suited for meeting the needs of the gifted. While many studies have documented the effectiveness of this type of instruction, there is a lack of research on growth in higher-order thinking through participation in science inquiry. This study investigated such growth among a small group of gifted fifth-grade students. In this study a group of fifth-grade gifted science students completed a series of three forensics inquiry lessons, and documented questions, ideas and reflections as they constructed evidence to solve a crime. From this class of students, one small group was purposely selected to serve as the focus of the study. Using qualitative techniques, the questions and statements students made as they interacted in the activity were analyzed. Videotaped comments and student logs were coded for emerging patterns and also examined for evidence of increased levels of higher-order thinking based on a rubric that was designed using the six levels of Bloom's Taxonomy. Evidence from this study showed marked increase in and deeper levels of higher-order thinking for two of the students. The other boy and girl showed progress using the inquiry activities, but it was not as evident. The social dynamics of the group seemed to hinder one girl's participation during some of the activities. The social interactions played a role in strengthening the exchange of ideas and thinking skills for the others. The teacher had a tremendous influence over the production of higher-level statements by modeling that level of thinking as she questioned the students. Through her practice of answering a question with a question, she gradually solicited more analytical thinking from her students.

    This study investigated the effectiveness of an interactive vocabulary instructional strategy, semantic-feature analysis (SFA), on the content area text comprehension of adolescents with learning disabilities. Prior to reading a social studies text, students in resource classes either completed a relationship chart as part of the SFA condition or used the dictionary to write definitions and sentences as part of the contrast condition. Passage comprehension was measured on a multiple-choice test consisting of two types of items, vocabulary and conceptual. Comprehension was measured immediately following teaching and again 6 months after teaching. Prior knowledge for the content of the passage served as a covariate. Results indicated that students in the SFA instructional condition had significantly greater measured comprehension immediately following and 6 months after initial teaching. These results are discussed in relation to concept-driven, interactive strategies for teaching content and facilitating text comprehension.

    Cooperative learning may improve students' motivation, understanding of course concepts, and academic performance. This study therefore enhanced a cooperative, group-project learning technique with technology resources to determine whether doing so improved students' deep learning and performance. A sample of 118 engineering students, randomly divided into two groups, participated in this study and provided data through questionnaires issued before and after the experiment. The results, obtained through analyses of variance and structural equation modelling, reveal that technology-enhanced, cooperative, group-project learning improves students' comprehension and academic performance.

    Full Text Available Current conventional laboratory sessions for science undergraduate students are currently reported to fail in developing research competences. However, authentic research experiences, in and out of the laboratory, are becoming more common in introductory undergraduate science programs after the implantation of The Bologna Process. Project-based learning (PBL experiences based on inquiry-based protocols could be used to help students to identify and analyze the information they need to move into complex problems. Inquiry-based courses have been described in the past, where students participate in semester-long guided research projects focused in specific learning objectives (Hatfull et al. 2006; Call et al., 2007; Lopatto et al., 2008. During this last academic year we have designed a PBL model that provides an active learning laboratory experience based on an inquiry-based protocol for 2nd year Biotechnology students. We have designed a modular molecular genetics course that includes bioinformatics and molecular biology lab sessions. In both modules, students had the opportunity to conduct in collaborative groups different research projects about a central theme in molecular biology: the cell cycle. As they were responsible of their own projects, they becoming practicing scientists by proposing and evaluating biological experiments of their own design mentored by teacher facilitation. Final assessments included a thorough literature review about the central topic of the project and a final written paper resembling established publishing criteria for science research international journals. Students were also encouraged to contact well-known scientists in their research area by email during their bibliography search. From the satisfaction surveys, we conclude that results were positive in terms of student satisfaction (as measured in questionnaires and written reflections. This experience helped students understand the strengths, limitations and

    探究式教学强调以学生的发展为本,倡导自主、合作的探究方式,注重培养学生的实践能力和创新精神。但以往教学实践中,探究式教学的实效性常会受到学生、教师、教材三个层面因素的制约。我们抓住“探究”与“实效”两个核心要素,以探究“知识链、能力链、方法链”为切入点,以学科建设、教材梳理、教程设计、学力培养为基本点,构建新的课堂教学模式和教学策略,推进学科建设,提升教学质量,促进校本教研和教师发展,从而实现学校教育的新发展。%Inquiry-based teaching attached much importance on students' development,which. advocates the independent and collaborative inquiry and pay more attention on students' practical ability and creative spirit. However, in practice the effectiveness of inquiry-based teaching is always restricted by the students, teachers and textbooks. By taking the two key elements of inquiry and effectiveness, starting from the link of knowledge, ability and method and reinforcing subject development, textbook rearrangement , course design and the training of learning ability, we construct the new classroom teaching mode and strategy to promote the subject development and increase the teaching quality and promote the school-based teaching research and teacher development to realize the new development of school education.

    2013-04-29

    Reinforcement learning is a powerful mechanism for enabling agents to learn in an unknown environment, and most reinforcement learning algorithms aim to maximize some numerical value, which represents only one long-term objective. However, multiple long-term objectives are exhibited in many real-world decision and control problems; therefore, recently, there has been growing interest in solving multiobjective reinforcement learning (MORL) problems with multiple conflicting objectives. The aim of this paper is to present a comprehensive overview of MORL. In this paper, the basic architecture, research topics, and naive solutions of MORL are introduced at first. Then, several representative MORL approaches and some important directions of recent research are reviewed. The relationships between MORL and other related research are also discussed, which include multiobjective optimization, hierarchical reinforcement learning, and multi-agent reinforcement learning. Finally, research challenges and open problems of MORL techniques are highlighted.

    The Alabama Comprehensive Cancer Control Coalition (ACCCC) has developed an integrated and coordinated approach to reducing cancer incidence, morbidity, and mortality, and to improving the quality of life for cancer survivors, their families, and their caregivers. The ACCCC is currently in a maintenance phase and a formal plan for sustainability of the coalition was needed to keep the members engaged and productive. A training session in coalition sustainability conducted in 2013 identified the following elements as essential to success: (1) increased marketing of the coalition by simplifying its mission; (2) improved networking including flexibility in coalition meeting location and attendance; (3) increased membership satisfaction through transformational leadership; (4) revision of the working structure of committees and improved accountability; and (5) enhancement of partner satisfaction with coalition activities designed to recruit and retain new partners. A self-administered membership satisfaction survey was given to assess coalition mission, meeting logistics, organization, capacity building, and coalition goals. Results indicated that the subcategories of communication, mission, and meeting logistics were rated satisfied to very satisfied on a five-point scale. Although the ACCCC had clearly written goals, improvement could be made in leadership participation and new member orientation could be improved. Most members rated their parent organization as highly involved with the ACCCC and many offered suggestions on capacity building. Results of the sustainability training have clarified the ACCCC's plans to ensure coalition viability and improve strategies to inform stakeholders of the benefits of participation in the coalition.

    Science graduates require critical thinking skills to deal with the complex problems they will face in their 21st century workplaces. Inquiry-based curricula can provide students with the opportunities to develop such critical thinking skills; however, evidence suggests that an inappropriate level of autonomy provided to underprepared students may not only be daunting to students but also detrimental to their learning. After a major review of the Bachelor of Science, we developed, implemented, and evaluated a series of three vertically integrated courses with inquiry-style laboratory practicals for early-stage undergraduate students in biomedical science. These practical curricula were designed so that students would work with increasing autonomy and ownership of their research projects to develop increasingly advanced scientific thinking and communication skills. Students undertaking the first iteration of these three vertically integrated courses reported learning gains in course content as well as skills in scientific writing, hypothesis construction, experimental design, data analysis, and interpreting results. Students also demonstrated increasing skills in both hypothesis formulation and communication of findings as a result of participating in the inquiry-based curricula and completing the associated practical assessment tasks. Here, we report the specific aspects of the curricula that students reported as having the greatest impact on their learning and the particular elements of hypothesis formulation and communication of findings that were more challenging for students to master. These findings provide important implications for science educators concerned with designing curricula to promote scientific thinking and communication skills alongside content acquisition.

    The importance of grammar knowledge has al-ways been neglected in reading comprehension. To help English teachers and learners see the value of grammar analysis, this pa-per, therefore, explores the correlation between grammar and reading comprehension. Forty-four freshmen of English majors were involved in the experiment, completing two tests of grammar and reading comprehension respectively, and it was followed by a personal interview for some exceptional cases after a week. The result of data analysis shows that grammar analysis accompanying with vocabulary, emotion, as well as other factors produce an ef-fect on learners’reading comprehension to a certain degree. It is suggested that language teachers as well as learners therefore should attach importance to learning grammatical knowledge.

    2010-01-01

    This work examines the role of morphological awareness in contrast to phonological processing in reading comprehension amongst two groups of native Arabic children: a group with learning disabilities (LD) and a mainstream group who were matched to the LD group in age or reading level. Measures of reading comprehension fluency, phonological skills, and morphological ability were given to both groups in addition to tests of nonverbal ability. For the mainstream children, unique variability in comprehension was predicted by the morphological measures over that of the measures of phonological skills and general nonverbal ability. In contrast, for the LD data, variability in comprehension was not predicted by morphological ability even though the children with LD performed the morphology task as well as their typically developing peers did. These findings are discussed in terms of theories of reading acquisition across languages as well as recommendations for literacy teaching and LD intervention in Arabic.

    Negishi, Meiko

    Student achievement and motivation to learn physics is highly valued in many industrialized countries including the United States and Japan. Science education curricula in these countries emphasize the importance and encourage classroom teachers to use an inquiry approach. This dissertation investigated high school students' motivational orientations and their understanding of physics concepts in a context of inquiry-based instruction. The goals were to explore the patterns of instructional effects on motivation and learning in each country and to examine cultural differences and similarities. Participants consisted of 108 students (55 females, 53 males) and 9 physics teachers in the United States and 616 students (203 females and 413 males) and 11 physics teachers in Japan. Students were administered (a) Force Concept Inventory measuring physics conceptual understanding and (b) Attitudes about Science Questionnaire measuring student motivational orientations. Teachers were given a survey regarding their use of inquiry teaching practices and background information. Additionally, three teachers in each country were interviewed and observed in their classrooms. For the data analysis, two-level hierarchical linear modeling (HLM) methods were used to examine individual student differences (i.e., learning, motivation, and gender) within each classroom (i.e., inquiry-based teaching, teaching experience, and class size) in the U.S. and Japan, separately. Descriptive statistical analyses were also conducted. The results indicated that there was a cultural similarity in that current teaching practices had minimal influence on conceptual understanding as well as motivation of high school students between the U.S. and Japan. In contrast, cultural differences were observed in classroom structures and instructional approaches. Furthermore, this study revealed gender inequity in Japanese students' conceptual understanding and self-efficacy. Limitations of the study, as well as

    Humphrey, Robert James, Jr.

    Research studies over the past 30 years have found that individuals have a limited understanding of the theory of evolution and the mechanisms involved in species change. One possible avenue of improvement has been the use of alternative instructional methods, such as inquiry-based activities and teaching about nature of science. Using recommendations from research, this study integrated nature of science, evolution, and inquiry-based instruction to discern its impact on student understanding of evolution. An instructional unit was developed with a community college instructor and carried out in two introductory biology classes with a total of 38 participants. One class was taught using inquiry-based methods, with an integrated approach to nature of science and evolution, while the other was not. Data collection included student and instructor interviews, surveys, pre and post assessments, classroom observations, and student work products. The number of students holding accurate conceptions of the nature of science in the inquiry class was higher for all the reported categories on the posttest. Despite less direct exposure to evolution concepts in lecture, the inquiry class had higher means on two separate posttests for evolution. The traditional class performed better on the pretests yet the inquiry class had higher posttest scores on both measures. Students in the inquiry class held a positive view of the inquiry-based methods and they cited them as a reason for their understanding of evolution. Individuals indicated that the integration of nature of science and evolution allowed them to grasp the concepts of evolution better than if evolution was taught alone. A creationist student became more accepting of evolution and also improved her understanding of evolution. Another student interviewed four years after the intervention remembered only the inquiry-based unit and was able to still use examples from class to explain natural selection. The instructor had a

    Kostenbader, Tracy C.

    Due to the logistics of guided-inquiry lesson, students learn to problem solve and develop critical thinking skills. This mixed-methods study analyzed the students' attitudes towards science during inquiry lessons. My quantitative results from a repeated measures survey showed no significant difference between student attitudes when taught with either structured-inquiry or guided-inquiry lessons. The qualitative results analyzed through a constant-comparative method did show that students generate positive interest, critical thinking and low level stress during guided-inquiry lessons. The qualitative research also gave insight into a teacher's transition to guided-inquiry. This study showed that with my students, their attitudes did not change during this transition according to the qualitative data however, the qualitative data did how high levels of excitement. The results imply that students like guided-inquiry laboratories, even though they require more work, just as much as they like traditional laboratories with less work and less opportunity for creativity.

    2010-02-01

    This study examined the effectiveness of introducing elementary teachers to the scholarly literature on personal pronouns and hedges in classroom discourse, a professional development strategy adopted during a summer institute to enhance teachers’ social understanding (i.e., their understanding of the social functions of language in science discussions). Teachers became aware of how hedges can be employed to remain neutral toward students’ oral contributions to classroom discussions, invite students to share their opinions and articulate their own ideas, and motivate students to inquire. Teachers recognized that the combined use of I and you can render their feedback authoritative, you can shift the focus from the investigation to students’ competence, and we can lead to authority loss. It is argued that explicitness, reflectivity, and contextualization are essential features of professional development programs aimed at improving teachers’ understandings of the social dimension of inquiry-based science classrooms and preparing teachers to engage in inquiry-based teacher-student interactions.

    Full Text Available Human activity recognition (HAR is an important research area in the fields of human perception and computer vision due to its wide range of applications. These applications include: intelligent video surveillance, ambient assisted living, human computer interaction, human-robot interaction, entertainment, and intelligent driving. Recently, with the emergence and successful deployment of deep learning techniques for image classification, researchers have migrated from traditional handcrafting to deep learning techniques for HAR. However, handcrafted representation-based approaches are still widely used due to some bottlenecks such as computational complexity of deep learning techniques for activity recognition. However, approaches based on handcrafted representation are not able to handle complex scenarios due to their limitations and incapability; therefore, resorting to deep learning-based techniques is a natural option. This review paper presents a comprehensive survey of both handcrafted and learning-based action representations, offering comparison, analysis, and discussions on these approaches. In addition to this, the well-known public datasets available for experimentations and important applications of HAR are also presented to provide further insight into the field. This is the first review paper of its kind which presents all these aspects of HAR in a single review article with comprehensive coverage of each part. Finally, the paper is concluded with important discussions and research directions in the domain of HAR.

    Patke, Usha

    Achievement data from the 3rd International Mathematics and Sciences Study and Program for International Student Assessment in science have indicated that Black students from economically disadvantaged families underachieve at alarming rates in comparison to White and economically advantaged peer groups. The study site was a predominately Black, urban school district experiencing underachievement. The purpose of this correlational study was to examine the relationship between students' use of inquiry-based laboratory investigations and their performance on the Biology End of Course Test, as well as to examine the relationship while partialling out the effects of student gender. Constructivist theory formed the theoretical foundation of the study. Students' perceived levels of experience with inquiry-based laboratory investigations were measured using the Laboratory Program Variable Inventory (LPVI) survey. LPVI scores of 256 students were correlated with test scores and were examined by student gender. The Pearson correlation coefficient revealed a small direct correlation between students' experience in inquiry-based laboratory investigation classes and standardized test scores on the Biology EOCT. A partial correlational analysis indicated that the correlation remained after controlling for gender. This study may prompt a change from teacher-centered to student-centered pedagogy at the local site in order to increase academic achievement for all students. The results of this study may also influence administrators and policy makers to initiate local, state, or nationwide curricular development. A change in curriculum may promote social change as students become more competent, and more able, to succeed in life beyond secondary school.

    The laboratory setting is an exciting and gratifying place to teach because you can actively engage the students in the learning process through hands-on activities; it is a dynamic environment amenable to collaborative work, critical thinking, problem-solving and discovery. The guided inquiry-based approach described here guides the students through their laboratory work at a steady pace that encourages them to focus on quality observations, careful data collection and thought processes surrounding the chemistry involved. It motivates students to work in a collaborative manner with frequent opportunities for feedback, reflection, and modification of their ideas. Each laboratory activity has four stages to keep the students' efforts on track: pre-lab work, an in-lab discussion, in-lab work, and a post-lab assignment. Students are guided at each stage by an instructor created template that directs their learning while giving them the opportunity and flexibility to explore new information, ideas, and questions. These templates are easily transferred into an electronic journal (termed the E-notebook) and form the basic structural framework of the final lab reports the students submit electronically, via a learning management system. The guided-inquiry based approach presented here uses a single laboratory activity for undergraduate Introductory Biochemistry as an example. After implementation of this guided learning approach student surveys reported a higher level of course satisfaction and there was a statistically significant improvement in the quality of the student work. Therefore we firmly believe the described format to be highly effective in promoting student learning and engagement.

  12. THE PSYCHOLOGICAL NATURE OF TEXT COMPREHENSION IN TERMS OF TEXT LEARNING PROCESSES

    2013-06-01

    Full Text Available Texts are important tools for learning. Thus, the attempt to make texts more understandable is a reflection of a purpose-function related necessity for learning from text. On the other hand, the idea of development and recovery of informative texts via corrective teaching materials is frequently explored by contemporary researchers. Thus, it is evident that more advanced proficiency is needed for the illustrated aspect of the structure of texts in the learning process and to make the efforts to prepare educational materials at more scientific ground. Therefore, in this study textual organization and a general theory of learning from texts are outlined and later language processing in working memory and related phenomena about learning from texts and individual differences including information about texts development, texts comprehension, and inferences from texts are discussed. The reason for this is the idea that working memory is responsible for not only recalling the stored information but also for storing the results of partial processes such as successive processes like language comprehension as explained in the related literature for modern memory theories. The other reason is the generalizations about the interaction between the processes of physical representation and pattern of a text manifested in accordance with these ideas. Additionally, not only the different procedures used to develop informative texts, at the same time, differences of these procedures including a learner’s view of world and process styles and measurement of text comprehension and the complex relations among them are the current and available information in the literature. As a result, due to the nature of factors, which affect a learner’s level of recalling and his understanding from text, this study aims to discuss this assumptions.

    Full Text Available Reading comprehension is a significant concern for adolescents with learning disabilities (LD, particularly in secondary schools in the United States (US where content is taught primarily through textbooks. Surprisingly little is known about the actual reading instruction for students with LD in secondary classrooms. Thus, the purpose of this study was to examine the reading comprehension instruction in US secondary special education classrooms. Eight special education teachers in urban high schools were observed and interviewed. Findings showed that teachers implemented a number of reading comprehension practices, not all were considered “best practice”. The most frequently observed practices included reading aloud, questioning, seatwork, activating prior knowledge, and using graphic organizers. Explicit instruction in how and when to use reading comprehension strategies, however, was not observed. This study reveals the extent to which evidence-based reading comprehension practices are not making their way into secondary reading classrooms and offers insight into factors that teachers state as influencing their instruction for students with LD.

    The quality of science teaching is of growing importance in Mexico. Mexican students score well below the world mean in math and science. Although the government has recognized these deficiencies and has implemented new policies aimed to improve student achievement in the sciences, teachers are still encountering in-class barriers to effective teaching, especially in public colleges. This paper reports on the utility of inquiry based exercises in Mexican classrooms. In particular, it describes a two-day professional development workshop with science teachers at the Instituto Tecnologico Superior in Felipe Carrillo Puerto in the Mexican state of Quintana Roo. Felipe Carrillo Puerto is an indigenous municipality where a significant majority of the population speak Maya as their first language. This alone presents a unique barrier to teaching science in the municipality, but accompanied with other factors such as student apathy, insufficient prior training of both students and teachers, and pressure to deliver specific science curriculum, science teachers have formidable challenges for effective science teaching. The goals of the workshop were to (1) have a directed discussion regarding science as both content and process, (2) introduce inquiry based learning as one tool of teaching science, and (3) get teachers to think about how they can apply these techniques in their classes.

  19. Making sense of shared sense-making in an inquiry-based science classroom: Toward a sociocultural theory of mind

    Science.gov (United States)

    Ladewski, Barbara G.

    Despite considerable exploration of inquiry and reflection in the literatures of science education and teacher education/teacher professional development over the past century, few theoretical or analytical tools exist to characterize these processes within a naturalistic classroom context. In addition, little is known regarding possible developmental trajectories for inquiry or reflection---for teachers or students---as these processes develop within a classroom context over time. In the dissertation, I use a sociocultural lens to explore these issues with an eye to the ways in which teachers and students develop shared sense-making, rather than from the more traditional perspective of individual teacher activity or student learning. The study includes both theoretical and empirical components. Theoretically, I explore the elaborations of sociocultural theory needed to characterize teacher-student shared sense-making as it develops within a classroom context, and, in particular, the role of inquiry and reflection in that sense-making. I develop a sociocultural model of shared sense-making that attempts to represent the dialectic between the individual and the social, through an elaboration of existing sociocultural and psychological constructs, including Vygotsky's zone of proximal development and theory of mind. Using this model as an interpretive framework, I develop a case study that explores teacher-student shared sense-making within a middle-school science classroom across a year of scaffolded introduction to inquiry-based science instruction. The empirical study serves not only as a test case for the theoretical model, but also informs our understanding regarding possible developmental trajectories and important mechanisms supporting and constraining shared sense-making within inquiry-based science classrooms. Theoretical and empirical findings provide support for the idea that perspectival shifts---that is, shifts of point-of-view that alter relationships

    Adapting a successful inquiry-based immersion program to create an Authentic, Hands-on, Field based Curriculum in Environmental Science at Barnard College T. C. Kenna, S. Pfirman, B. J. Mailloux, M. Stute, R. Kelsey, and P. Bower By adapting a successful inquiry-based immersion program (SEA semester) to the typical college format of classes, we are improving the technical and quantitative skills of undergraduate women and minorities in environmental science and improving their critical thinking and problem-solving by exposing our students to open-ended real-world environmental issues. Our approach uses the Hudson River Estuary as a natural laboratory. In a series of hands-on inquiry-based activities, students use advanced equipment to collect data and samples. Each class session introduces new analytical and data analysis techniques. All classes have the connecting theme of the river. Working with real data is open-ended. Our major findings as indicated by surveys as well as journaling throughout the semester are that the field- based experience significantly contributed to student learning and engagement. Journaling responses indicated that nearly all students discussed the importance and excitement of an authentic research experience. Some students were frustrated with data irregularities, uncertainty in methods and data, and the general challenge of a curriculum with inherent ambiguity. The majority were satisfied with the aims of the course to provide an integrative experience. All students demonstrated transfer of learned skills. This project has had a significant impact on our undergraduate female students: several students have pursued senior thesis projects stemming from grant activities, stating that the field activities were the highlight of their semester. Some students love the experience and want more. Others decide that they want to pursue a different career. All learn how science is conducted and have a better foundation to understand concepts such

  2. Teacher-student interaction: The overlooked dimension of inquiry-based professional development

    de Oliveira, Alandeom Wanderlei

    This study explores the teacher-student interactional dimension of inquiry-based science instruction. In it, microethnographic and grounded theory analyses are conducted in order to assess the impact of a professional development program designed to enhance in-service elementary teachers' interactional views (i.e., their understandings of inquiry-based social roles and relationships) and discursive practices (i.e., teachers' abilities to interact with student engaged in classroom inquiries) through a combination of expert instruction, immersion in scientific inquiry, and collaborative analysis of video-recorded classroom discourse. A sociolinguistic theoretical perspective on language use is adopted, viewing classroom discourse as comprising multiple linguistic signs (questions, responses, personal pronouns, hedges, backchannels, reactive tokens, directives, figures of speech, parallel repetitions) that convey not only semantic meanings (the literal information being exchanged) but also pragmatic meanings (information about teachers and students' social roles and relationships). A grounded theory analysis of the professional development activities uncovered a gradual shift in teachers' interactional views from a cognitive, monofunctional and decontextualized perspective to a social, multifunctional and contextualized conception of inquiry-based discourse. Furthermore, teachers developed increased levels of pragmatic awareness, being able to recognize the authoritative interactional functions served by discursive moves such as display questions, cued elicitation, convergent questioning, verbal cloze, affirmation, explicit evaluations of students' responses, verbatim repetitions, IRE triplets, IR couplets, second-person pronouns, "I/you" contrastive pairs, and direct or impolite directives. A comparative microethnographic analysis of teachers' classroom practices revealed that after participating in the program teachers demonstrated an improved ability to share

    Full Text Available The Reading, Engaging, and Learning project (REAL investigated whether a classroom intervention that enhanced young children's experience with informational books would increase reading achievement and engagement. Participants attended schools serving low income neighborhoods with 86% African American enrollment. The longitudinal study spanned second through fourth grades. Treatment conditions were: (1 Text Infusion/Reading for Learning Instruction -- students were given greater access to informational books in their classroom libraries and in reading instruction; (2 Text Infusion Alone -- the same books were provided but teachers were not asked to alter their instruction; (3 Traditional Instruction -- students experienced business as usual in the classroom. Children were assessed each year on measures of reading and reading engagement, and classroom instructional practices were observed. On most measures, the informational text infusion intervention did not yield differential growth over time. However, the results inform efforts to increase children’s facility with informational text in the early years in order to improve reading comprehension.

    Suters, Leslie Ann

    Five urban teachers completed a total of 50 contact hours of professional development in which they: participated in authentic, inquiry-based experiences facilitated by a scientist; learned new science content related to the nature of science and scientific inquiry; developed inquiry-based lesson plans to implement in their classrooms; and developed science-specific strategies to mentor novice and experienced teachers. The focus of this research was to determine changes in their: beliefs and instructional practices; understanding of scientific literacy; and efficacy toward mentoring other teachers. A collective case study methodology was used in which participants completed questionnaires and were observed and interviewed, prior to and at the completion of the course. They were also asked to complete reflective journal questions during the course. While the teachers' beliefs did not change as measured by the Teacher's Pedagogical Philosophy Interview (TPPI) (teacher-centered beliefs for "Teacher Actions" and "Teacher and Content"; conceptual/student-centered for "Student Actions" and "Philosophy of Teaching"), their teacher-centered behaviors changed to conceptual/student-centered as measured by the Secondary Science Teachers Analysis Matrix (STAM). Their responses to the Constructivist Learning Environment Survey (CLES) generally correlated with their post-STAM results. Participants gained a better understanding of the creative aspect of the nature of science as measured by the Modified Nature of Scientific Knowledge Scale (MNSKS) instrument, while two novice teachers improved their personal science teaching efficacy after participation in the course as measured by the Science Teaching Efficacy Belief Instrument (STEBI). Four of the five teachers felt better prepared to mentor others to use inquiry-based instruction. In contrast to these positive trends, their outcome expectancy beliefs (STEBI subscale) were generally lower than their perceived personal teaching

    Geospatial literacy -- the ability to conceptualize, capture, analyze and communicate spatial phenomena -- represents an important competency for 21st Century learners in a period of 'Geospatial Revolution'. Though relevant to in-course learning, these skills are often taught externally, placing time and resource pressures on the service providers - commonly libraries - that are relied upon to provide instruction. The emergence of online and blended modes of instruction has presented a potential means of increasing the cost-effectiveness of such activities, by simultaneously reducing instructional costs, expanding the audience for these resources, and addressing student preferences for asynchronous learning and '24-7' access. During 2011 and 2012, McMaster University Library coordinated the development, implementation and assessment of blended learning modules for geospatial literacy instruction in first-year undergraduate Social Science courses. In this paper, we present the results of a comprehensive mixed-methods approach to assess the efficacy of implementing blended learning modules to replace traditional (face-to-face), library-led, first-year undergraduate geospatial literacy instruction. Focus groups, personal interviews and an online survey were used to assess modules across dimensions of: student use, satisfaction and accessibility requirements (via Universal Instructional Design [UID] principles); instructor and teaching staff perception of pedagogical efficacy and instructional effectiveness; and, administrator cost-benefit assessment of development and implementation. Results showed that both instructors and students identified significant value in using the online modules in a blended-learning setting. Reaffirming assumptions of students' '24/7' learning preferences, over 80% of students reported using the modules on a repeat basis. Students were more likely to use the modules to better understand course content than simply to increase their grade in

    2009-07-30

    The Comprehensive Test Ban Treaty (CTBT) is gaining renewed attention in light of growing worldwide interest in mitigating risks of nuclear weapons proliferation and testing. Since the International Monitoring System (IMS) installed the first suite of sensors in the late 1990's, the IMS network has steadily progressed, providing valuable support for event diagnostics. This progress was highlighted at the recent International Scientific Studies (ISS) Conference in Vienna in June 2009, where scientists and domain experts met with policy makers to assess the current status of the CTBT Verification System. A strategic theme within the ISS Conference centered on exploring opportunities for further enhancing the detection and localization accuracy of low magnitude events by drawing upon modern tools and techniques for machine learning and large-scale data analysis. Several promising approaches for data exploitation were presented at the Conference. These are summarized in a companion report. In this paper, we introduce essential concepts in machine learning and assess techniques which could provide both incremental and comprehensive value for event discrimination by increasing the accuracy of the final data product, refining On-Site-Inspection (OSI) conclusions, and potentially reducing the cost of future network operations.

    The present study investigated developmental changes in lexical comprehension skills in early sequential bilinguals, in both Spanish (L1) and English (L2), exploring the effects of age, years of experience, and basic-level cognitive processing (specifically the ability to maintain performance during mixed vs. single-language processing) within a timed picture-word verification task. Participants were 100 individuals, 20 at each of five different age levels (ages in years, 5-7, 8-10, 11-13, 14-16, and adults). All had learned Spanish as a first language in the home, with formal English experience beginning at 5 years. Gains (as indexed by increased response speed) were made in both languages across age, although these gains were greater in English than in Spanish. The youngest participants were relatively "balanced" in their crosslinguistic performance. By middle childhood, performance was better in English. There were no response decrements at any age between the mixed and single-language processing conditions. These results are compared to those from a previous study that investigated basic-level lexical production in developing Spanish-English bilinguals. Both studies show a move toward English dominance in middle childhood, but the transition occurs earlier in comprehension. The production study showed differences between mixed and single-language processing (reflecting potential interlanguage interference) that are not evident in comprehension.

    The exploration process leading to the understanding of physical phenomena, such as light and its interaction with matter, raises great interest and curiosity in children. However, in most primary schools, children rarely have the opportunity to conduct science activities in which they can engage in an enquiry process even if by the action of the teacher. In this context, we have organised several in-service teacher training courses and carried out several pedagogic interventions in Portuguese primary schools, with the aim of promoting inquiry- based science education. This article describes one of those projects, developed with a class of the third grade, which explored the curricular topic “Light Experiments”. Various activities were planned and implemented, during a total of ten hours spread over five lessons. The specific objectives of this paper are: to illustrate and analyse the teaching and learning process promoted in the classroom during the exploration of one of these lessons, and to assess children's learning three weeks after the lessons. The results suggest that children made significant learning which persisted. We conclude discussing some processes that stimulated children’ learning, including the importance of teacher questioning in scaffolding children's learning and some didactic implications for teacher training.

    A method of weapon detection for the Comprehensive nuclear-Test-Ban-Treaty (CTBT) consists of monitoring the amount of radioxenon in the atmosphere by measuring and sampling the activity concentration of {sup 131m}Xe, {sup 133}Xe, {sup 133m}Xe, and {sup 135}Xe by radionuclide monitoring. Several explosion samples were simulated based on real data since the measured data of this type is quite rare. These data sets consisted of different circumstances of a nuclear explosion, and are used as training data sets to establish an effective classification model employing state-of-the-art technologies in machine learning. A study was conducted involving classic induction algorithms in machine learning including Naive Bayes, Neural Networks, Decision Trees, k-Nearest Neighbors, and Support Vector Machines, that revealed that they can successfully be used in this practical application. In particular, our studies show that many induction algorithms in machine learning outperform a simple linear discriminator when a signal is found in a high radioxenon background environment.

    2014-07-01

    The purpose of this research was to build and test a conceptual model of the complex interrelationships between students' learning in science (learning approaches and self-regulation), their reading comprehension, question-asking in class and science achievement. These variables were measured by means of a test and a series of questionnaires administered to 604 ninth-grade students, and the data collected were analysed using a correlational, cross-sectional design. Results of a path analysis indicated that (a) students' self-regulated and intentional knowledge-constructing activity (self-regulated strategy use, deep approach and knowledge-building) were what chiefly accounted for their question-asking in class; (b) question-asking (high and low levels) was related directly to reading comprehension and indirectly, through its contribution to the this, to academic achievement; (c) reading comprehension was directly and negatively associated with surface approach and indirectly and positively related to deep approach and knowledge-building; and (d) some of these variables, particularly reading comprehension, accounted for academic achievement in science. This model explained nearly 30% of the variance in academic achievement and provided a substantial and distinctive insight into the web of interrelationships among these variables. Implications for future research and science teaching and learning are discussed (e.g. the importance of supporting students' efforts to learn science in a meaningful, active and self-regulated way and of improving their reading comprehension).

  16. Pattern identification or 3D visualization? How best to learn topographic map comprehension

    Science.gov (United States)

    Atit, Kinnari

    Science, Technology, Engineering, and Mathematics (STEM) experts employ many representations that novices find hard to use because they require a critical STEM skill, interpreting two-dimensional (2D) diagrams that represent three-dimensional (3D) information. The current research focuses on learning to interpret topographic maps. Understanding topographic maps requires knowledge of how to interpret the conventions of contour lines, and skill in visualizing that information in 3D (e.g. shape of the terrain). Novices find both tasks difficult. The present study compared two interventions designed to facilitate understanding for topographic maps to minimal text-only instruction. The 3D Visualization group received instruction using 3D gestures and models to help visualize three topographic forms. The Pattern Identification group received instruction using pointing and tracing gestures to help identify the contour patterns associated with the three topographic forms. The Text-based Instruction group received only written instruction explaining topographic maps. All participants then completed a measure of topographic map use. The Pattern Identification group performed better on the map use measure than participants in the Text-based Instruction group, but no significant difference was found between the 3D Visualization group and the other two groups. These results suggest that learning to identify meaningful contour patterns is an effective strategy for learning how to comprehend topographic maps. Future research should address if learning strategies for how to interpret the information represented on a diagram (e.g. identify patterns in the contour lines), before trying to visualize the information in 3D (e.g. visualize the 3D structure of the terrain), also facilitates students' comprehension of other similar types of diagrams.

    Full Text Available We describe an inquiry-based course in physics and chemistry for preservice K-8 teachers developed at California State University Fullerton. The course is one of three developed primarily to enhance the science content understanding of prospective teachers. The course incorporates a number of innovative instructional strategies and is somewhat unusual for its interdisciplinary focus. We describe the course structure in detail, providing examples of course materials and assessment strategies. Finally, we provide research data illustrating both the need for the course and the effectiveness of the course in developing student understanding of selected topics. Student responses to various questions reflect a lack of understanding of many relatively simple physical science concepts, and a level of performance that is usually lower than that in comparable courses serving a general education audience. Additional data suggest that course activities improve student understanding of selected topics, often dramatically.

  20. Science teachers' online strategies for seeking inquiry-based lesson activities

    Science.gov (United States)

    Lenell, Elizabeth Ann

    This paper reports the findings of a mixed methods study that examines how 9th grade science teachers engage in online searches for inquiry-based activities in two different search engines---Google and the Digital Library for Earth System Education. The goal of this dissertation was two-fold: (a) to detail science teacher search behaviors during a realistic online search task related to their teaching, and (b) the effect of search engine affordances on those search practices. At the center of the dissertation activities were an experimental task and talk-aloud protocols of the teachers engaged in the task. The task itself asked teacher participants to search for earth science activities linking the concept of volcanism to plate tectonics. In addition to the experiment and talk-aloud protocol, a demographic survey, content knowledge evaluation, inquiry-based activity evaluation, and post-task structured interview were conducted. Because substantial prior research in non-educational areas has shown that task domain influences search behaviors, it was expected that the science teaching domain would have its own particular influence on teachers' online information seeking. The concept of task domain was developed in terms of an information seeking framework developed by Marchionini (1995). The Marchionini (1995) model of information seeking was used as a guiding framework for the dissertation investigations. The objectives of this dissertation were to characterize the behaviors and products of real-world online information seeking by 9th grade science teachers, and to inform the work of educational software designers.

    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.

    Full Text Available AbstractPurpose: To study reading comprehension performance profiles of children with dyslexia as well as language-based learning disability by means of retelling tasks. Method: 105 children from second to fifth grades of elementary school were gathered into six groups: Dyslexia group (D; n=19, Language-based learning disability group (LBLD; n=16; their respective control groups paired according to different variables - age, gender, grade and school system (public or private (D-control and LBLD-control; and other control groups paired according to different reading accuracy (D-accuracy; LBLD-accuracy. All of the children read an expository text and orally retold the story as they understood it. The analysis quantified propositions (main ideas and details and retold links. A retelling reference standard (3-0 was also established from the best to the worst performance. We compared both clinical groups (D and LBLD with their respective control groups by means of Mann-Whitney tests.Results: D showed the same total of propositions, links and reference standards as D-control, but performed better than D-accuracy in macro structural (total of links and super structural (retelling reference standard measures. Results suggest that dyslexic children are able to use their linguistic competence and their own background knowledge to minimize the effects of their decoding deficit, especially at the highest text processing levels. LBLD performed worse than LBLD-control in all of the retelling measures and LBLD showed worse performance than LBLD-accuracy in the total retold links and retelling reference standard. Those results suggest that both decoding and linguistic difficulties affect reading comprehension. Moreover, the linguistic deficits presented by LBLD students do not allow these pupils to perform as competently in terms of text comprehension as the children with dyslexia do. Thus, failure in the macro and super-structural information processing of the

    Gunderson, Angelica E.

    This project was designed to incorporate three curriculum development strategies that have been created to increase student achievement in various content areas. Conceptual flow design, the 5E Instructional Model, and English language development strategies were used to create a seventh grade Genetics Unit. The unit was evaluated by three external experts and carried out in two seventh grade classrooms in an effort to assess its effectiveness. Based on the evaluators' feedback, the initial conceptual flow and lessons were found to be inconsistent and confusing. Overall, the organization of this unit seemed to support student achievement. The conceptual flow and the lesson layout of the unit were revised based on the evaluation data. All revisions and the established protocols will serve as models for further science curriculum development in the Norwalk-La Mirada Unified School District.

    1999-01-01

    This study compared two highly dissimilar approaches for teaching students to determine character motive when reading three types of narrative text. The three text types used were textually explicit, textually implicit, and scriptually implicit. The two approaches were an explicit rule-based instruction approach and a basal-reader activity-based approach. Forty students with learning disabilities were randomly assigned to either the explicit rule-based or the basal-reader activity-based instructional group. Daily instructional sessions lasted 45 minutes and were conducted for 2 weeks. The groups were evaluated on four comprehension measures: (a) daily retells of stories, (b) unit tests, (c) a transfer measure, and (d) a maintenance measure. The results suggest that rule-based instruction is superior to an activity-based approach when teaching students with learning disabilities to determine character motives irrespective of text type on short-term measures. However, there were no significant differences between the two instructional groups on the maintenance and transfer tests.

  7. A novel comprehensive learning artificial bee colony optimizer for dynamic optimization biological problems

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available There are many dynamic optimization problems in the real world, whose convergence and searching ability is cautiously desired, obviously different from static optimization cases. This requires an optimization algorithm adaptively seek the changing optima over dynamic environments, instead of only finding the global optimal solution in the static environment. This paper proposes a novel comprehensive learning artificial bee colony optimizer (CLABC for optimization in dynamic environments problems, which employs a pool of optimal foraging strategies to balance the exploration and exploitation tradeoff. The main motive of CLABC is to enrich artificial bee foraging behaviors in the ABC model by combining Powell’s pattern search method, life-cycle, and crossover-based social learning strategy. The proposed CLABC is a more bee-colony-realistic model that the bee can reproduce and die dynamically throughout the foraging process and population size varies as the algorithm runs. The experiments for evaluating CLABC are conducted on the dynamic moving peak benchmarks. Furthermore, the proposed algorithm is applied to a real-world application of dynamic RFID network optimization. Statistical analysis of all these cases highlights the significant performance improvement due to the beneficial combination and demonstrates the performance superiority of the proposed algorithm.

  8. Multiswarm comprehensive learning particle swarm optimization for solving multiobjective optimization problems

    Yu, Xiang; Zhang, Xueqing

    2017-01-01

    Comprehensive learning particle swarm optimization (CLPSO) is a powerful state-of-the-art single-objective metaheuristic. Extending from CLPSO, this paper proposes multiswarm CLPSO (MSCLPSO) for multiobjective optimization. MSCLPSO involves multiple swarms, with each swarm associated with a separate original objective. Each particle’s personal best position is determined just according to the corresponding single objective. Elitists are stored externally. MSCLPSO differs from existing multiobjective particle swarm optimizers in three aspects. First, each swarm focuses on optimizing the associated objective using CLPSO, without learning from the elitists or any other swarm. Second, mutation is applied to the elitists and the mutation strategy appropriately exploits the personal best positions and elitists. Third, a modified differential evolution (DE) strategy is applied to some extreme and least crowded elitists. The DE strategy updates an elitist based on the differences of the elitists. The personal best positions carry useful information about the Pareto set, and the mutation and DE strategies help MSCLPSO discover the true Pareto front. Experiments conducted on various benchmark problems demonstrate that MSCLPSO can find nondominated solutions distributed reasonably over the true Pareto front in a single run. PMID:28192508

    1997-01-01

    This study examined the contributions of instruction in goal setting and self-instruction, separately and combined, on the acquisition, maintenance, and generalization of a reading comprehension strategy by fourth-through sixth-grade students with learning disabilities. A previously validated strategy involving the use of story structure to analyze and remember story content was taught to 47 students with learning disabilities using the self-regulated strategy development (SRSD) model. Comparisons were made among students with learning disabilities in four conditions (strategy instruction, strategy instruction plus goal setting, strategy instruction plus self-instruction, and strategy instruction plus goal setting and self-instruction). Result indicated that instruction in the reading strategy produced meaningful, lasting, and generalizable effects on students' story comprehension skills. Furthermore, the comprehension performance of the students with learning disabilities after strategy instruction was indistinguishable from that of a social comparison group of normally achieving students. Explicit instruction in goal setting and self-instruction, however, did not augment the comprehension performance of students with learning disabilities.

    In a secondary-level Earth System Science (ESS) curriculum, the most authentic learning is achieved through the inquiry-based application of real-world research methods in the context of modern understanding of the interconnected components of the Earth System (e.g. lithosphere, hydrosphere, atmosphere, and biosphere). Following the intensive ESST-1 summer institute at UNH, during which teachers enhance their ESS content knowledge via interactions with UNH faculty, staff, and graduate students, each participating teacher is paired with one graduate student fellow for the duration of the school year. This graduate fellow provides a continuing link between the secondary-level school teaching environment and university resources, facilitating the implementation of new content knowledge and current scientific research methodology into the classroom setting. According to the National Science Education Standards (1), scientific inquiry is the central strategy for teaching science. "In successful science classrooms, teachers and students collaborate in the pursuit of ideas... Students formulate questions and devise ways to answer them, they collect data and decide how to represent it, they organize data to generate knowledge, and they test the reliability of the knowledge they have generated. As they proceed, students explain and justify their work to themselves and to one another, learn to cope with problems such as the limitations of equipment, and react to challenges posed by the teacher and by classmates." To speak to these goals, an ongoing local wetland field study has been conceptualized and implemented in three example classrooms (seventh grade general science, ninth grade physical science and tenth grade biology) in two school systems (Oyster River Middle School in Durham, NH and Berlin High School in Berlin, NH). These field studies were conducted using authentic scientific equipment to collect data, including a Li-Cor 840 infrared CO2 analyzer and handmade

    Full Text Available In order to meet the reading needs of English as-a-Foreign-Language (EFL learners, educators are urged to develop effective instructional means for teaching reading comprehension and reading strategy use. Although studies on foreign language reading strategies are burgeoning in the realm of language acquisition research, recent interest has spotlighted learners’ metacognitive awareness of strategies. This study investigated the effect of metacognitive strategy training on the reading comprehension of 111 intermediate EFL learners. The participants received five sessions of instruction on metacognitive strategies guided by the blueprints of Cognitive Academic Language Learning Approach (CALLA. The results of t-test, and two-ways analysis of variance (ANOVA revealed that there was a significant positive relationship between the students' metacognitive reading strategy use and their reading comprehension performance. There was also a significant positive relationship between the use of CALLA and the students' reading comprehension performance.

  20. Lessons Learned from the First Decade of Adaptive Management in Comprehensive Everglades Restoration

    Directory of Open Access Journals (Sweden)

    Andrew J. LoSchiavo

    2013-12-01

    Full Text Available Although few successful examples of large-scale adaptive management applications are available to ecosystem restoration scientists and managers, examining where and how the components of an adaptive management program have been successfully implemented yields insight into what approaches have and have not worked. We document five key lessons learned during the decade-long development and implementation of the Comprehensive Everglades Restoration Plan (CERP Collaborative Adaptive Management Program that might be useful to other adaptive management practitioners. First, legislative and regulatory authorities that require the development of an adaptive management program are necessary to maintain funding and support to set up and implement adaptive management. Second, integration of adaptive management activities into existing institutional processes, and development of technical guidance, helps to ensure that adaptive management activities are understood and roles and responsibilities are clearly articulated so that adaptive management activities are implemented successfully. Third, a strong applied science framework is critical for establishing a prerestoration ecosystem reference condition and understanding of how the system works, as well as for providing a conduit for incorporating new scientific information into the decision-making process. Fourth, clear identification of uncertainties that pose risks to meeting restoration goals helps with the development of hypothesis-driven strategies to inform restoration planning and implementation. Tools such as management options matrices can provide a coherent way to link hypotheses to specific monitoring efforts and options to adjust implementation if performance goals are not achieved. Fifth, independent external peer review of an adaptive management program provides important feedback critical to maintaining and improving adaptive management implementation for ecosystem restoration. These lessons

  2. Impact of backwards faded scaffolding approach to inquiry-based astronomy laboratory experiences on undergraduate non-science majors' views of scientific inquiry

    Science.gov (United States)

    Lyons, Daniel J.

    NOSI. According to the results of a Wilcoxon Signed Rank test, there was a significant shift in the distributions of both samples toward a more informed understanding of DvE after the intervention curriculum was administered, while there was no significant change in either direction for understanding of MMS. The results of the instructor interview analysis suggested that the intervention curriculum provided multiple opportunities for students to evaluate and determine the relevance of data in the context of producing evidence-based conclusions directly related to specific research questions, thereby supporting the development of more informed views of DvE. These results also suggested that students might not have realized that they were exclusively engaged in non-experimental type inquiries, as various research methods were not explicitly addressed. The intervention curriculum used a consistently phased stepwise format, which may also have led the students to accommodate their astronomy inquiry experiences within persistent misconceptions of "The Scientific Method" as the only valid means of constructing scientific knowledge, thereby leading to no change in understanding of MMS. The results of the study suggest that a scaffolded, inquiry-based, introductory astronomy laboratory curriculum purposefully designed and scaffolded to enhance students' understandings could be effective in enhancing undergraduate non-science majoring students' views of certain aspects of NOSI. Through scaffolding inquiry experiences that deliver multiple opportunities to engage in authentic scientific inquiries, the novel curriculum provides a valuable resource for the astronomy education community to engage students in learning experiences that reflect the contemporary views of constructivist inquiry-based learning, which focuses on the interpretation of data to create evidence in light of specific questions, as well as opportunities to engage in authentic scientific discourse.

    2013-11-01

    Full Text Available Recent progress in grapheme-color synesthesia research has revealed that certain regularities, as well as individual differences, figure into grapheme-color associations. Although several factors are known to regulate grapheme-color associations, the impact of factors, including their interrelationships, on synesthesia remains unclear. We investigated determinants of synesthetic color for graphemes (characters, letters of Hiragana, a phonetic script in the Japanese language, and the English alphabet. Results revealed that grapheme ordinality was the strongest predictor of synesthetic colors for Hiragana characters, followed by character sound, and visual shape. Ordinality and visual shapes also significantly predicted synesthetic colors for English alphabet letters, however, sounds did not. The relative impact of grapheme properties on grapheme-color associations and the differences between these two writing systems are accounted for by considering the way graphemes are processed in the brain and introduced during an individual's development. A new model is proposed which takes into account the developmental process of grapheme learning. The model provides comprehensive explanation of synesthetic grapheme-color association determination processes, including the differences across writing systems.

The model provides comprehensive explanation of synesthetic grapheme-color association determination processes, including the differences across writing systems.

    2015-05-01

    Building on the 'questioning-based discourse analytical' framework developed by Singapore-based science educator and discourse analyst, Christine Chin, this study investigated the extent to which fifth-grade science teachers' use of questions with either an authoritative or dialogic orientation differentially restricted or expanded the quality and complexity of student responses in the USA. The author analyzed approximately 10 hours of classroom discourse from elementary science classrooms organized around inquiry-based science curricula and texts. Teacher questions and feedback were classified according to their dialogic orientation and contextually inferred structural purpose, while student understanding was operationalized as a dynamic interaction between cognitive process, syntacto-semantic complexity, and science knowledge type. The results of this study closely mirror Chin's and other scholars' findings that the fixed nature of authoritatively oriented questioning can dramatically limit students' opportunities to demonstrate higher order scientific understanding, while dialogically oriented questions, by contrast, often grant students the discursive space to demonstrate a greater breadth and depth of both canonical and self-generated knowledge. However, certain teacher questioning sequences occupying the 'middle ground' between maximal authoritativeness and dialogicity revealed patterns of meaningful, if isolated, instances of higher order thinking. Implications for classroom practice are discussed along with recommendations for future research.

    2013-01-01

    A new primary science syllabus with strong inquiry focus has been implemented in Singapore since 2008. In this study, we attempted to understand how teachers experience the emphasis of inquiry-based curriculum under the current educational conditions that is routined and highly teacher fronted. We invited 50 pre-service and 41 in-service teachers to participate in survey questionnaires and narratives, reflective writings, and group discussions related to science inquiry which formed our data corpus. Data analysis in the form of thematic coding was carried out using NVivo8, with over 80% inter-rater coding agreement level. Three key aspects of teachers' perceptions of science inquiry were revealed: (1) teachers' responsibilities as facilitators, (2) privileging content knowledge rather than process skills, and (3) pressure of assessment systems in current educational contexts. These understandings bring out conflicts of inquiry teaching between teacher- and student-centredness, content and process, and curriculum and assessment. Based on these teachers' perceptions and dilemmas of inquiry science teaching, the visions and challenges of inquiry science curriculum change against assessment requirements are discussed.

    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.

  8. An Inquiry-Based Laboratory Module to Promote Understanding of the Scientific Method and Bacterial Conjugation

    Full Text Available Students are engaged and improve their critical thinking skills in laboratory courses when they have the opportunity to design and conduct inquiry-based experiments that generate novel results. A discovery-driven project for a microbiology, genetics, or multidisciplinary research laboratory course was developed to familiarize students with the scientific method. In this multi-lab module, students determine whether their chosen stress conditions induce conjugation and/or cell death of the model BSL-1 Gram-positive bacterium Bacillus subtilis. Through consultation of the primary literature, students identify conditions or chemicals that can elicit DNA damage, the SOS response, and/or cellular stress.  In groups, students discuss their selected conditions, develop their hypotheses and experimental plans, and formulate their positive and negative controls. Students then subject the B. subtilis donor cells to the stress conditions, mix donors with recipients to allow mating, and plate serial dilutions of the mixtures on selective plates to measure how the treatments affect conjugation frequency and donor cell viability.  Finally, students analyze and discuss their collective data in light of their controls. The goals of this module are to encourage students to be actively involved in the scientific process while contributing to our understanding of the conditions that stimulate horizontal gene transfer in bacteria.

    This study investigates the effects of an intensive 1-week Inquiry-Based Science and Technology Enrichment Program (InSTEP) designed for middle school-aged female students. InSTEP uses a guided/open inquiry approach that is deepened and redefined as eight sciences and engineering practices in the Next Generation Science Standards, which aimed at increasing female students' interest in science and science-related careers. This study examined the effectiveness of InSTEP on 123 female students' pre-assessment and post-assessment changes in attitudes toward science and content knowledge of selected science concepts. An attitude survey, a science content test with multiple-choice questions, written assignments, and interviews to collect data were all used to measure students' attitudes and content knowledge. A within-group, repeated measure design was conducted, and the results indicated that at the post-intervention level, InSTEP increased the participants' positive attitudes toward science, science-related careers, and content knowledge of selected science concepts.

    2010-01-01

    We have designed an inquiry-based laboratory activity on transiting extrasolar planets for an introductory college-level astronomy class. The activity was designed with the intent of simultaneously teaching science process skills and factual content about transits and light curves. In the activity, groups of two to four students each formulate a specific science question and design and carry out an investigation using a table-top model of a star and orbiting planet. Each group then presents their findings to other students in their class. In a final presentation, the instructors integrate students' findings with a summary of how measured light curves indicate properties of planetary systems. The activity debuted at Hartnell College in November 2009 and has also been adapted for a lecture-based astronomy course at U.C. Santa Cruz. We present the results of student surveys before and after the astronomy course at Hartnell and discuss how well our activity promotes students' confidence and identity as scientists...

    Full Text Available This article aims (1 to describe the levels of self-regulation and reading comprehension of scientific expository texts; (2 to establish the relationship between self-regulation and reading comprehension; and (3 to compare the performance in comprehension when the printed media (paper or digital media (computer is used. A quasi-experimental, quantitative, descriptive and correlative design was implemented. The sample was composed of 55 university students from four careers of Education; they were in 1st and 3rd year of study at a regional university of the Council of Rectors of Chilean Universities. Three measuring instruments were used: a questionnaire of self-regulated learning and two comprehension tests based on the understanding of Parodi’s (2005 assessment model. The implementation was made in two consecutive moments; first, the self-questionnaire; then, the tests for reading comprehension in both media. With the data obtained, statistical tests of variance, one-way ANOVA, Pearson’s correlation, and means comparison with Bruner and Munzel and U-Mann Whitney’s tests were calculated. In conclusion, and different from the initial statement, it was obtained that university students have an adequate level of self-regulation and low reading comprehension in both data, even the scores are relatively lower in digital data. In both data the output is inverse to the complexity of the questions. Between 1st and 3rd year, there is no increase either in the self-regulation or in reading comprehension; but, exceptionally, the career of Primary General Education specialist on Language and History did. There is a strong relationship between reading comprehension in printed media and self-regulation (ARATEX. The support does not affect reading comprehension, but individual reading skills of the subjects do. A competent reader will have similar performance in both reading supports.

    1998-01-01

    Listening comprehension and recall abilities for social studies lectures were examined and compared in 20 adolescent males with language-learning disabilities (LLD) and 29 without disabilities (WD). Subjects viewed two social studies lectures with comparison and causation expository discourse structures and verbally responded to literal and inferential comprehension questions. Regardless of lecture type or question type, the group with LLD performed significantly more poorly than did the group WD. Both groups responded accurately to significantly more inferential questions for the causation lecture over the comparison lecture. Neither group demonstrated a significant difference with respect to their response accuracy for the literal questions across lecture types.

    Genomics is the core subject of various "omics" and it also becomes a topic of increasing interest in undergraduate curricula of biological sciences. However, the study on teaching methodology of genomics courses was very limited so far. Here we report an application of inquiry-based teaching in genomics courses by using virulence factors of Escherichia coli as an example of comparative genomics study. Specially, students first built a multiple-genome alignment of different E. coli strains to investigate the gene conservation using the Mauve tool; then putative virulence factor genes were identified by using BLAST tool to obtain gene annotations. The teaching process was divided into five modules: situation, resources, task, process and evaluation. Learning-assessment results revealed that students had acquired the knowledge and skills of genomics, and their learning interest and ability of self-study were also motivated. Moreover, the special teaching case can be applied to other related courses, such as microbiology, bioinformatics, molecular biology and food safety detection technology.

    Bhattacharyya, Sumita; Volk, Trudi; Lumpe, Andrew

    2009-06-01

    This study examined the effects of an extensive inquiry-based field experience on pre service elementary teachers’ personal agency beliefs, a composite measure of context beliefs and capability beliefs related to teaching science. The research combined quantitative and qualitative approaches and included an experimental group that utilized the inquiry method and a control group that used traditional teaching methods. Pre- and post-test scores for the experimental and control groups were compared. The context beliefs of both groups showed no significant change as a result of the experience. However, the control group’s capability belief scores, lower than those of the experimental group to start with, declined significantly; the experimental group’s scores remained unchanged. Thus, the inquiry-based field experience led to an increase in personal agency beliefs. The qualitative data suggested a new hypothesis that there is a spiral relationship among teachers’ ability to establish communicative relationships with students, desire for personal growth and improvement, ability to implement multiple instructional strategies, and possession of substantive content knowledge. The study concludes that inquiry-based student teaching should be encouraged in the training of elementary school science teachers. However, the meaning and practice of the inquiry method should be clearly delineated to ensure its correct implementation in the classroom.

    Ellwood, Robin; Abrams, Eleanor

    2017-02-01

    This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged 13-14 years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on 46 % of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. Implications for science teaching and future research include shifting the current focus in inquiry-based science from a continuum that progresses from teacher-directed to open inquiry experiences to a

  17. Deep learning for digital pathology image analysis: A comprehensive tutorial with selected use cases

    Science.gov (United States)

    Janowczyk, Andrew; Madabhushi, Anant

    2016-01-01

    Background: Deep learning (DL) is a representation learning approach ideally suited for image analysis challenges in digital pathology (DP). The variety of image analysis tasks in the context of DP includes detection and counting (e.g., mitotic events), segmentation (e.g., nuclei), and tissue classification (e.g., cancerous vs. non-cancerous). Unfortunately, issues with slide preparation, variations in staining and scanning across sites, and vendor platforms, as well as biological variance, such as the presentation of different grades of disease, make these image analysis tasks particularly challenging. Traditional approaches, wherein domain-specific cues are manually identified and developed into task-specific “handcrafted” features, can require extensive tuning to accommodate these variances. However, DL takes a more domain agnostic approach combining both feature discovery and implementation to maximally discriminate between the classes of interest. While DL approaches have performed well in a few DP related image analysis tasks, such as detection and tissue classification, the currently available open source tools and tutorials do not provide guidance on challenges such as (a) selecting appropriate magnification, (b) managing errors in annotations in the training (or learning) dataset, and (c) identifying a suitable training set containing information rich exemplars. These foundational concepts, which are needed to successfully translate the DL paradigm to DP tasks, are non-trivial for (i) DL experts with minimal digital histology experience, and (ii) DP and image processing experts with minimal DL experience, to derive on their own, thus meriting a dedicated tutorial. Aims: This paper investigates these concepts through seven unique DP tasks as use cases to elucidate techniques needed to produce comparable, and in many cases, superior to results from the state-of-the-art hand-crafted feature-based classification approaches. Results: Specifically, in this

    Greenwald, Ralf R; Quitadamo, Ian J

    2014-01-01

    A changing undergraduate demographic and the need to help students develop advanced critical thinking skills in neuroanatomy courses has prompted many faculty to consider new teaching methods including clinical case studies. This study compared primarily conventional and inquiry-based clinical case (IBCC) teaching methods to determine which would produce greater gains in critical thinking and content knowledge. Results showed students in the conventional neuroanatomy course gained less than 3 national percentile ranks while IBCC students gained over 7.5 within one academic term using the valid and reliable California Critical Thinking Skills Test. In addition to 2.5 times greater gains in critical thinking, IBCC teaching methods also produced 12% greater final exam performance and 11% higher grades using common grade performance benchmarks. Classroom observations also indicated that IBCC students were more intellectually engaged and participated to a greater extent in classroom discussions. Through the results of this study, it is hoped that faculty who teach neuroanatomy and desire greater critical thinking and content student learning outcomes will consider using the IBCC method.

  20. Using Eight Key Questions as an Inquiry-Based Framework for Ethical Reasoning Issues in a General Education Earth Systems and Climate Change Course

    Science.gov (United States)

    Johnson, E. A.; Ball, T. C.

    2014-12-01

    An important objective in general education geoscience courses is to help students evaluate social and ethical issues based upon scientific knowledge. It can be difficult for instructors trained in the physical sciences to design effective ways of including ethical issues in large lecture courses where whole-class discussions are not practical. The Quality Enhancement Plan for James Madison University, "The Madison Collaborative: Ethical Reasoning in Action," (http://www.jmu.edu/mc/index.shtml) has identified eight key questions to be used as a framework for developing ethical reasoning exercises and evaluating student learning. These eight questions are represented by the acronym FOR CLEAR and are represented by the concepts of Fairness, Outcomes, Responsibilities, Character, Liberty, Empathy, Authority, and Rights. In this study, we use the eight key questions as an inquiry-based framework for addressing ethical issues in a 100-student general education Earth systems and climate change course. Ethical reasoning exercises are presented throughout the course and range from questions of personal behavior to issues regarding potential future generations and global natural resources. In the first few exercises, key questions are identified for the students and calibrated responses are provided as examples. By the end of the semester, students are expected to identify key questions themselves and justify their own ethical and scientific reasoning. Evaluation rubrics are customized to this scaffolding approach to the exercises. Student feedback and course data will be presented to encourage discussion of this and other approaches to explicitly incorporating ethical reasoning in general education geoscience courses.

    Thweatt, A. M.; Giardino, J. R.; Schroeder, C.

    2014-12-01

    Scientific literacy and inquiry-based writing go together like a hand and glove. Science literacy, defined by NRC in The NSF Standards, stresses the relationship between knowledge of science and skill in literacy so "a person can ask, find, or determine answers to questions derived from curiosity about everyday experiences. It means that a person has the ability to describe, explain, and predict natural phenomena. Scientific literacy entails being able to read with understanding articles about science in the popular press and to engage in social conversation about the validity of the conclusions. Scientific literacy implies that a person can identify scientific issues underlying national and local decisions and express positions that are scientifically and technologically informed." A growing body of research and practice in science instruction suggests language is essential in the practice of the geosciences. Writing and critical thinking are iterative processes. We use this approach to educate our geoscience students to learn, write, and think critically. One does not become an accomplished writer via one course. Proficiency is gained through continued exposure, guidance and tailored assignments. Inquiry-based geoscience makes students proficient in the tools of the geosciences and to develop explanations to questions about Earth events. We have scaffolded our courses from introductory geology, English composition, writing in the geosciences, introduction to field methods and report writing to do more critical thinking, research data gatherings, and in-depth analysis and synthesis. These learning experiences that encourage students to compare their reasoning models, communicate verbally, written and graphically. The English composition course sets the stage for creative assignments through formulation of original research questions, collection of primary data, analysis, and construction of written research papers. Proper use of language allows students to clarify

  9. Using inquiry-based instruction to meet the standards of No Child Left Behind for middle school earth science

    Science.gov (United States)

    Harris, Michael W.

    This study examined the effectiveness of a specific instructional strategy employed to improve performance on the end-of-the-year Criterion-Referenced Competency Test (CRCT) as mandated by the No Child Left Behind (NCLB) Act of 2001. A growing body of evidence suggests that the perceived pressure to produce adequate aggregated scores on the CRCT causes teachers to neglect other relevant aspects of teaching and attend less to individualized instruction. Rooted in constructivist theory, inquiry-based programs provide a o developmental plan of instruction that affords the opportunity for each student to understand their academic needs and strengths. However, the utility of inquiry-based instruction is largely unknown due to the lack of evaluation studies. To address this problem, this quantitative evaluation measured the impact of the Audet and Jordan inquiry-based instructional model on CRCT test scores of 102 students in a sixth-grade science classroom in one north Georgia school. A series of binomial tests of proportions tested differences between CRCT scores of the program participants and those of a matched control sample selected from other district schools that did not adopt the program. The study found no significant differences on CRCT test scores between the treatment and control groups. The study also found no significant performance differences among genders in the sample using inquiry instruction. This implies that the utility of inquiry education might exist outside the domain of test scores. This study can contribute to social change by informing a reevaluation of the instructional strategies that ideally will serve NCLB high-stakes assessment mandates, while also affording students the individual-level skills needed to become productive members of society.

    2013-01-01

    The American Psychiatric Association's proposed definition of specific learning disability ("specific learning disorder") for the DSM-5 reflects current thinking and best practice in learning disabilities. It continues the core conceptualization of learning disability (LD) as well as proposes identification criteria to supplant the discredited aptitude-achievement discrepancy formula. Improvements can be found along with long-standing and new controversies about the nature of LD. The proposed definition both provides a model of a currently acceptable definition and reflects critical issues in the operationalization of LD that the field continues to neglect.

    2015-09-01

    Students entering medical college generally show vast diversity in their school education. It becomes the responsibility of teachers to motivate students and meet the needs of all diversities. One such measure is teaching students in their own preferred learning style. The present study was aimed to incorporate a learning style-based teaching-learning program for medical students and to reveal its significance and utility. Learning styles of students were assessed online using the visual-auditory-kinesthetic (VAK) learning style self-assessment questionnaire. When respiratory physiology was taught, students were divided into three groups, namely, visual (n = 34), auditory (n = 44), and kinesthetic (n = 28), based on their learning style. A fourth group (the traditional group; n = 40) was formed by choosing students randomly from the above three groups. Visual, auditory, and kinesthetic groups were taught following the appropriate teaching-learning strategies. The traditional group was taught via the routine didactic lecture method. The effectiveness of this intervention was evaluated by a pretest and two posttests, posttest 1 immediately after the intervention and posttest 2 after a month. In posttest 1, one-way ANOVA showed a significant statistical difference (P=0.005). Post hoc analysis showed significance between the kinesthetic group and traditional group (P=0.002). One-way ANOVA showed a significant difference in posttest 2 scores (P < 0.0001). Post hoc analysis showed significance between the three learning style-based groups compared with the traditional group [visual vs. traditional groups (p=0.002), auditory vs. traditional groups (p=0.03), and Kinesthetic vs. traditional groups (p=0.001)]. This study emphasizes that teaching methods tailored to students' style of learning definitely improve their understanding, performance, and retrieval of the subject.

    Full Text Available Background: Since the end of last century, technology has taken a front seat in dispersion of medical education. Advancements of technology in neurosurgery and traditional training methods are now being challenged by legal and ethical concerns of patient safety, resident work-hour restriction and cost of operating-room time. To supplement the existing neurosurgery education pattern, various e-learning platforms are introduced as structured, interactive learning system. Materials and Methods: This study focuses on the concept, formulation, development and impact of web based learning platforms dedicated to neurosurgery discipline to disseminate education, supplement surgical knowledge and improve skills of neurosurgeons. ′Neurosurgery Education and Training School (NETS, e-learning platform′ has integration of web-based technologies like ′Content Management System′ for organizing the education material and ′Learning Management System′ for updating neurosurgeons. NETS discussion forum networks neurosurgeons, neuroscientists and neuro-technologists across the globe facilitating collaborative translational research. Results: Multi-authored neurosurgical e-learning material supplements the deficiencies of regular time-bound education. Interactive open-source, global, free-access e-learning platform of NETS has around 1 425 visitors/month from 73 countries; ratio of new visitors to returning visitors 42.3; 57.7 (2; 64,380 views from 190 subscribers for surgical videos, 3-D animation, graphics based training modules (3; average 402 views per post. Conclusion: The e-Learning platforms provide updated educational content that make them "quick, surf, find and extract" resources. e-Learning tools like web-based education, social interactive platform and question-answer forum will save unnecessary expenditure of time and travel of neurosurgeons seeking knowledge. The need for free access platforms is more pronounced for the neurosurgeons and

    Full Text Available This study reports an investigation into the impact of a structured foundational staff development program on new academics in their role as classroom tutors in a problem-based learning (PBL environment. The program aims to pro vide a systematic framework to share knowledge, skills and attitudes necessary for new a cademics to be competent and confident tutors who can provide valued and valuable learning experiences for students’ learning in a PBL environment. To measure the outcomes of this pr ogram, Kirkpatrick’s (1994 framework was adopted, and outcomes were evaluated according to reaction, learning, and behavior. Quantitative data were collected in the form of stu dent feedback scores, tutor confidence, and attitudes toward teaching, while a post-program sur vey was used to collect qualitative data. The results indicate that the program had brought a bout gains in knowledge regarding principles and/or strategies of self-directed learn ing, as well as a detectable change in academics’ orientation towards teaching and learnin g to a more developmental perspective. Moreover, participants noted that they were able to apply their learning in terms of promoting key student behaviors in PBL, such as collaborative learning. The evaluation suggests that, for the successful implementation of PBL, it is importa nt for a structured foundational training program to address not only the essential elements of PBL, but also the role of the tutor, especially in terms of addressing the teaching beli efs of staff, and helping them to adapt to the constructivist belief system embedded in the PBL en vironment.

    2014-08-01

    Full Text Available This study was an attempt to investigate the effect of two types of learning, competitive and cooperative, on the reading comprehension of introvert and extrovert EFL learners. To this end, 120 learners studying at Marefat English Language Institute in Tehran, Iran were selected, after taking a Preliminary English Test (PET, to participate in this quasi-experimental research. The participants  also answered the Eysenck Personality Inventory (EPI to categorize them into two personality types of introverts and extroverts. Therefore, there were four subgroups: 30 introverts and 30 extroverts undergoing the cooperative learning treatment, and 30 introverts and 30 extroverts experiencing the competitive learning treatment. The reading part of the PET was administered as the posttest of the study after each group was exposed to the treatment for 18 sessions in seven weeks. A two-way ANOVA was run on the collected data in the posttest of four groups. The results revealed that while learners generally outperformed in the competitive setting compared to the cooperative one, the extrovert was better off receiving cooperative instruction. Moreover, introverts excelled extroverts in the competitive group. However, there was no difference between the two personality groups in the cooperative situation.

    2009-01-01

    The patient-centered medical home (PCMH) recently has received much attention in health systems literature. The PCMH holds considerable promise for improving health outcomes and re-establishing a role for family medicine in a fragmented health care system. Despite its philosophical approach to comprehensive health care reform, the PCMH fails to offer concrete recommendations to address the social determinants of health, which include health and social policy. Political engagement to promote health is part of both primary health care and specifically family medicine's history; the absence of practical, adaptable ways to implement this engagement may undermine the PCMH's ultimate goals of improving individual and population health.

    2015-06-01

    Full Text Available This study attempts to shed light on how learners' exact attention can be in line with learning  meaningfully and bring about remarkable changes in the learning ability of upper-intermediate EFL learners through employing certain learning strategy items with the aim of enhancing reading scores and consequently injecting into learners a sense of satisfaction with their work. Additionally, this study aimed to investigate the relationship of metacognitive, cognitive, and social/affective strategies with EFL learners’ reading comprehension. To this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. Each group received one main strategy and then, according to Oxford (1990 training model, the students were exposed to those strategies accompanied with reading comprehension texts. Learners’ progress and also the relationship of those strategies with reading comprehension were measured during the sixteen sessions of teaching and employing the strategies. Independent sample T-Test with Pearson correlations indicated that metacognitive group significantly outperformed the other groups, so metacognitive strategies were more in line with EFL learners’ reading comprehension.Keywords: Learning strategy, Metacognitive, Cognitive, Social/Affective strategy, Reading comprehension

  11. Comprehensive Cognitive Assessments are not Necessary for the Identification and Treatment of Learning Disabilities.

    Science.gov (United States)

    Fletcher, Jack M; Miciak, Jeremy

    2017-02-01

    There is considerable controversy about the necessity of cognitive assessment as part of an evaluation for learning and attention problems. The controversy should be adjudicated through an evaluation of empirical research. We review five sources of evidence commonly provided as support for cognitive assessment as part of the learning disability (LD) identification process, highlighting significant gaps in empirical research and where existing evidence is insufficient to establish the reliability and validity of cognitive assessments used in this way. We conclude that current evidence does not justify routine cognitive assessment for LD identification. As an alternative, we offer an instructional conceptualization of LD: a hybrid model that directly informs intervention and is based on documenting low academic achievement, inadequate response to intensive interventions, and a consideration of exclusionary factors.

    Kida, Adriana de S. B.; de Ávila, Clara R. B.; Capellini, Simone A.

    2016-01-01

    Purpose: To study reading comprehension performance profiles of children with dyslexia as well as language-based learning disability (LBLD) by means of retelling tasks. Method: One hundred and five children from 2nd to 5th grades of elementary school were gathered into six groups: Dyslexia group (D; n = 19), language-based learning disability group (LBLD; n = 16); their respective control groups paired according to different variables – age, gender, grade and school system (public or private; D-control and LBLD-control); and other control groups paired according to different reading accuracy (D-accuracy; LBLD-accuracy). All of the children read an expository text and orally retold the story as they understood it. The analysis quantified propositions (main ideas and details) and retold links. A retelling reference standard (3–0) was also established from the best to the worst performance. We compared both clinical groups (D and LBLD) with their respective control groups by means of Mann–Whitney tests. Results: D showed the same total of propositions, links and reference standards as D-control, but performed better than D-accuracy in macro structural (total of links) and super structural (retelling reference standard) measures. Results suggest that dyslexic children are able to use their linguistic competence and their own background knowledge to minimize the effects of their decoding deficit, especially at the highest text processing levels. LBLD performed worse than LBLD-control in all of the retelling measures and LBLD showed worse performance than LBLD-accuracy in the total retold links and retelling reference standard. Those results suggest that both decoding and linguistic difficulties affect reading comprehension. Moreover, the linguistic deficits presented by LBLD students do not allow these pupils to perform as competently in terms of text comprehension as the children with dyslexia do. Thus, failure in the macro and super-structural information

Students that were taught by the collaborative teachers got both higher inquiry-based project reports’ scores than those that were taught separately by the teachers. Experimental group’s students got higher school monthly test scores than controlled groups. Suggestions for teachers’ high-end collaboration and future researcher are provided in this paper.

  6. A Very Different Non-Stressful Comprehensive Final Exam that Achieve Our Goals for Student Evaluation and Learning

    Science.gov (United States)

    Bhavsar, Suketu

    2015-08-01

    I will introduce the radical concept of a final exam where the questions are given beforehand, a method I first encountered as a graduate student at Princeton University from an outstanding and well known astrophysicist and exceptional teacher, Lyman Spitzer.Every Instructor aspires for students to master all the material covered. A comprehensive final can assess the breadth and depth of their learning. Students are required to review early material in light of later topics, create connections and integrate understanding, thus retaining knowledge for the long term. Comprehensive finals can therefore be a significant basis for student learning and evaluation, but are especially daunting for non-STEM majors in required GE synthesis STEM classes. The exam format proposed here calmed student fears and encouraged thorough review.Ten days before the exam students received 20-30 challenging, well-crafted, numbered questions that interconnected and spanned the entire range of topics. The key is crafting questions that lead to deeply understanding the subject matter and mastering skills to solve problems. At the final, each student was required to pick a number out of a hat and answer that numbered question in a 5-minute presentation. They also had to critically comment on 10 other presentations of their peers. They are graded equally on both.The exam sets up definite goals for a student. Equally important, it enhances collaborative learning and peer mentoring. The conceptual questions and problems that students are required to answer can be studied together in study groups. The final presentation is theirs and they are not only encouraged but required to be constructively critical of their peer presentations.I will provide examples of some of the conceptual and problem solving questions I used. These were crafted to interconnect and span the entire range of topics. This method requires students to be prepared for all of the multitude of crafted question encouraging

  7. The effect of different types of hypertext annotations on vocabulary recall, text comprehension, and knowledge transfer in learning from scientific texts

    Science.gov (United States)

    Wallen, Erik Stanley

    The instructional uses of hypertext and multimedia are widespread but there are still many questions about how to maximize learning from these technologies. The purpose of this research was to determine whether providing learners with a basic science text in addition to hypertext annotations, designed to support the cognitive processes of selection, organization, and integration (Mayer, 1997), would result in different types of learning. Learning was measured using instruments designed to measure learning corresponding to each of the three processes. For the purposes of this study, selection-level learning was defined analogous to Bloom's (Bloom, 1956) knowledge level of learning and was measured with a recognition test. Organization-level learning was defined analogous to Bloom's (1956) comprehension-level of learning and was measured with a short-answer recall test. Integration-level learning was defined analogous to Bloom's (1956) levels of analysis and synthesis and was measured with a transfer test. In experiment one, participants read a text describing how cell phones work and viewed either no annotations (control), or annotations designed to support the selection, organization, or integration of information. As predicted, participants who viewed the selection-level annotations did significantly better than control participants on the recognition test. Results indicate that, for this group of novice learners, lower-level annotations were the most helpful for all levels of learning. In experiment two, participants read the text and viewed either no annotations (control) or combinations of annotations including selection and organization, organization and integration, or selection and integration. No significant differences were found between groups in these experiments. The results are discussed in terms of both multimedia learning theory and text comprehension theory and a new visualization of the generative theory of multimedia learning is offered.

    2012-12-01

    High Scope Program (HSP) is a long-term project funded by NSC in Taiwan since 2006. It is designed to elevate the quality of science education by means of incorporating emerging science and technology into the traditional curricula in senior high schools. Quake-Catcher Network (QCN), a distributed computing project initiated by Stanford University and UC Riverside, encourages the volunteers to install the low-cost, novel sensors at home and school to build a seismic network. To meet both needs, we have developed a model curriculum that introduces QCN, earthquake science, and cloud computing into high school classrooms. Through professional development workshops, Taiwan cloud-based earthquake science learning platform, and QCN club on Facebook, we have worked closely with Lan-Yang Girl's Senior High School teachers' team to design workable teaching plans through a practical operation of seismic monitoring at home or school. However, some obstacles to learning appear including QCN installation/maintain problems, high self-noise of the sensor, difficulty of introducing earthquake sciences for high school teachers. The challenges of QCN outreach in Taiwan bring out our future plans: (1) development of easy, frequently updated, physics-based QCN-experiments for high school teachers, and (2) design of an interactive learning platform with social networking function for students.

    2009-12-01

    Watershed Watch (NSF 0525433) engages early undergraduate students from two-year and four-year colleges in student-driven full inquiry-based instruction in the biogeosciences. Program goals for Watershed Watch are to test if inquiry-rich student-driven projects sufficiently engage undeclared students (or noncommittal STEM majors) to declare a STEM major (or remain with their STEM major). The program is a partnership between two four-year campuses - the University of New Hampshire (UNH), and Elizabeth City State University (ECSU, in North Carolina); and two two-year campuses - Great Bay Community College (GBCC, in New Hampshire) and the College of the Albemarle (COA, in North Carolina). The program focuses on two watersheds: the Merrimack Ricer Watershed in New Hampshire and Massachusetts, and the Pasquotank River Watershed in Virginia and North Carolina. Both the terrestrial and aquatic components of both watersheds are evaluated using the student-driven projects. A significant component of this program is an intensive two-week Summer Research Institute (SRI), in which undeclared freshmen and sophomores investigate various aspects of their local watershed. Two Summer Research Institutes have been held on the UNH campus (2006 and 2008) and two on the ECSU campus (2007 and 2009). Students develop their own research questions and study design, collect and analyze data, and produce a scientific oral or poster presentation on the last day of the SRI. The course objectives, curriculum and schedule are presented as a model for dissemination for other institutions and programs seeking to develop inquiry-rich programs or courses designed to attract students into biogeoscience disciplines. Data from self-reported student feedback indicate the most important factors explaining high-levels of student motivation and research excellence in the program are: 1) working with committed, energetic, and enthusiastic faculty mentors, and 2) faculty mentors demonstrating high degrees of

    Full Text Available Use of probabilistic techniques has been demonstrated to learn air data parameters from surface pressure measurements. Integration of numerical models with wind tunnel data and sequential experiment design of wind tunnel runs has been demonstrated in the calibration of a flush air data sensing anemometer system. Development and implementation of a metamodeling method, Sequential Function Approximation (SFA, are presented which lies at the core of the discussed probabilistic framework. SFA is presented as a tool capable of nonlinear statistical inference, uncertainty reduction by fusion of data with physical models of variable fidelity, and sequential experiment design. This work presents the development and application of these tools in the calibration of FADS for a Runway Assisted Landing Site (RALS control tower. However, the multidisciplinary nature of this work is general in nature and is potentially applicable to a variety of mechanical and aerospace engineering problems.

    2013-04-01

    For instructors in natural science undergraduate programs, there is a clear need to have students explore and understand the scientific evidence of past climate variability and learn what this tells us about the role of humans in shaping present-day climate. Indeed, research in the field of paleoclimatology has provided data that identifies one of the most pressing challenges facing society—global warming. Herein lay my motivation to fill an important gap in my university's undergraduate program in geography and environmental studies. To that end, about a year ago I began to develop a new fourth-year course in paleoclimatology.

    Mertz, Pamela; Streu, Craig

    2015-01-01

    This article describes a synergistic two-semester writing sequence for biochemistry courses. In the first semester, students select a putative protein and are tasked with researching their protein largely through bioinformatics resources. In the second semester, students develop original ideas and present them in the form of a research grant proposal. Both projects involve multiple drafts and peer review. The complementarity of the projects increases student exposure to bioinformatics and literature resources, fosters higher-order thinking skills, and develops teamwork and communication skills. Student feedback and responses on perception surveys demonstrated that the students viewed both projects as favorable learning experiences.

  1. Effective, Active Learning Strategies for the Oceanography Classroom

    Science.gov (United States)

    Dmochowski, J. E.; Marinov, I.

    2014-12-01

    A decline in enrollment in STEM fields at the university level has prompted extensive research on alternative ways of teaching and learning science. Inquiry-based learning as well as the related "flipped" or "active" lectures, and similar teaching methods and philosophies have been proposed as more effective ways to disseminate knowledge in science classes than the traditional lecture. We will provide a synopsis of our experiences in implementing some of these practices into our Introductory Oceanography, Global Climate Change, and Ocean Atmosphere Dynamics undergraduate courses at the University of Pennsylvania, with both smaller and larger enrollments. By implementing tools such as at-home modules; computer labs; incorporation of current research; pre- and post-lecture quizzes; reflective, qualitative writing assignments; peer review; and a variety of in-class learning strategies, we aim to increase the science literacy of the student population and help students gain a more comprehensive knowledge of the topic, enhance their critical thinking skills, and correct misconceptions. While implementing these teaching techniques with college students is not without complications, we argue that a blended class that flexibly and creatively accounts for class size and science level improves the learning experience and the acquired knowledge. We will present examples of student assignments and activities as well as describe the lessons we have learned, and propose ideas for moving forward to best utilize innovative teaching tools in order to increase science literacy in oceanography and other climate-related courses.

    2011-07-01

    A 2-layer symbolic network model based on the equilibrium equations of the Rescorla-Wagner model (Danks, 2003) is proposed. The study first presents 2 experiments in Serbian, which reveal for sentential reading the inflectional paradigmatic effects previously observed by Milin, Filipović Đurđević, and Moscoso del Prado Martín (2009) for unprimed lexical decision. The empirical results are successfully modeled without having to assume separate representations for inflections or data structures such as inflectional paradigms. In the next step, the same naive discriminative learning approach is pitted against a wide range of effects documented in the morphological processing literature. Frequency effects for complex words as well as for phrases (Arnon & Snider, 2010) emerge in the model without the presence of whole-word or whole-phrase representations. Family size effects (Moscoso del Prado Martín, Bertram, Häikiö, Schreuder, & Baayen, 2004; Schreuder & Baayen, 1997) emerge in the simulations across simple words, derived words, and compounds, without derived words or compounds being represented as such. It is shown that for pseudo-derived words no special morpho-orthographic segmentation mechanism, as posited by Rastle, Davis, and New (2004), is required. The model also replicates the finding of Plag and Baayen (2009) that, on average, words with more productive affixes elicit longer response latencies; at the same time, it predicts that productive affixes afford faster response latencies for new words. English phrasal paradigmatic effects modulating isolated word reading are reported and modeled, showing that the paradigmatic effects characterizing Serbian case inflection have crosslinguistic scope.

  4. Influence of an extensive inquiry-based field experience on pre-service elementary student teachers' science teaching beliefs

    Bhattacharyya, Sumita

    This study examined the effects of an extensive inquiry-based field experience on pre-service elementary teachers' personal agency beliefs (PAB) about teaching science and their ability to effectively implement science instruction. The research combined quantitative and qualitative approaches within an ethnographic research tradition. A comparison was made between the pre and posttest scores for two groups. The experimental group utilized the inquiry method; the control group did not. The experimental group had the stronger PAB pattern. The field experience caused no significant differences to the context beliefs of either groups, but did to the capability beliefs. The number of college science courses taken by pre-service elementary teachers' was positively related to their post capability belief (p = .0209). Qualitative information was collected through case studies which included observation of classrooms, assessment of lesson plans and open-ended, extended interviews of the participants about their beliefs in their teaching abilities (efficacy beliefs), and in teaching environments (context beliefs). The interview data were analyzed by the analytic induction method to look for themes. The emerging themes were then grouped under several attributes. Following a review of the attributes a number of hypotheses were formulated. Each hypothesis was then tested across all the cases by the constant comparative method. The pattern of relationship that emerged from the hypotheses testing clearly suggests a new hypothesis that there is a spiral relationship among the ability to establish communicative relationship with students, desire for personal growth and improvement, and greater content knowledge. The study concluded that inquiry based student teaching should be encouraged to train school science teachers. But the meaning and the practice of the inquiry method should be clearly delineated to ensure its correct implementation in the classroom. A survey should be

  10. A study of the long term impact of an inquiry-based science program on student's attitudes towards science and interest in science careers

    Science.gov (United States)

    Gibson, Helen Lussier

    One reason science enrichment programs were created was to address the underrepresentation of women and minorities in science. These programs were designed to increase underrepresented groups' interest in science and science careers. One attempt to increase students' interest in science was the Summer Science Exploration Program (SSEP). The SSEP was a two week, inquiry-based summer science camp offered by Hampshire College for students entering grades seven and eight. Students who participated were from three neighboring school districts in Western Massachusetts. The goal of the program was to stimulate greater interest in science and scientific careers among middle school students, in particular among females and students of color. A review of the literature of inquiry-based science programs revealed that the effect of inquiry-based programs on students' attitudes towards science is typically investigated shortly after the end of the treatment period. The findings from this study contribute to our understanding of the long-term impact of inquiry-based science enrichment programs on students' attitude towards science and their interest in science careers. The data collected consisted of quantitative survey data as well as qualitative data through case studies of selected participants from the sample population. This study was guided by the following questions: (1) What was the nature and extent of the impact of the Summer Science Exploration Program (SSEP) on students' attitudes towards science and interest in science careers, in particular among females and students of color? (2) What factors, if any, other than participation in SSEP impacted students' attitude towards science and interest in scientific careers? (3) In what other ways, if any, did the participants benefit from the program? Conclusions drawn from the data indicate that SSEP helped participants maintain a high level of interest in science. In contrast, students who applied but were not accepted

  11. A case study of self-efficacy and attitudes toward science in an inquiry-based biology laboratory

    Laipply, Richelle Susan

    It is in the introductory college science class where future teachers of science and future scientists are trained. Research has shown that self-efficacy and attitudes toward science are linked to future enrollment in science courses, selection of a college major, and even to a science career. It is important to examine the effects of these and other factors which impact the undergraduate science experience so as to decrease the attrition from the sciences and to evaluate science teaching methodologies. The purpose of this case study was to examine the effect of an inquiry-based introductory biology laboratory on students' biology self-efficacy and attitudes toward science at an urban public university. Data were gathered from one laboratory section during a fifteen-week semester through the use of participant observations, interviews, and three administrations of the Biology Self-Efficacy Scale and the Test of Science-Related Attitudes . Results showed that the inquiry experience had a positive effect on students' attitudes toward science and increased their biology self-efficacy. Moreover, peer group collaborations and student interactions with the teaching assistant were found to facilitate the inquiry process and the development of positive attitudes and self-efficacy. The findings of this study have implications for the enhancement of the undergraduate experience in college science laboratories and are significant for all college science educators with regard to ways in which to structure laboratory instruction.

    A National Science Foundation Graduate Teaching Fellows in K- 12 Education program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/ ) partners UCLA faculty and graduate students (fellows) with urban middle and high school science teachers and their students to foster programs of science and engineering exploration that bring the environment of Los Angeles into the classroom. UCLA graduate fellows serve as scientists-in-residence at four partner schools to integrate inquiry-based science lessons, facilitate advancements in science content teaching, and ultimately, to improve their own science communication skills. As part of their fellowship, graduate students are required to develop inquiry-based lessons in their partner classroom. During the first two years of the project, the SEE-LA fellows have developed a range of inquiry-based activities, from invertebrate observations in an urban stream system, to water and home energy consumption surveys, to a school biodiversity investigation, to a school-wide alternative energy fair, to engineering the cleanup of environmental disasters, such as the recent oil spill in the Gulf of Mexico. Several of the current fellows have dissertation research in water resource related fields and are specifically integrating lessons specific to their research into their partner classrooms, including urban stream water quality, post-fire watershed behavior, beach water quality assessment and E. coli source tracking. This presentation will provide an overview of goals of the SEE-LA GK-12 program, development of inquiry-based water resource lessons and resulting engagement in the partner classrooms. University and local pre-college school partnerships provide an excellent opportunity to support the development of graduate student communication and teaching skills while also contributing significantly to the integration of science education into K-12 curriculum.

    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.

    2016-12-01

    In this paper, we present the results from a study of the impact on students involved in a large-scale inquiry-based astronomical high school education intervention in Australia. Students in this intervention were led through an educational design allowing them to undertake an investigative approach to understanding the lifecycle of stars more aligned with the `ideal' picture of school science. Through the use of two instruments, one focused on content knowledge gains and the other on student views of school science, we explore the impact of this design. Overall, students made moderate content knowledge gains although these gains were heavily dependent on the individual teacher, the number of times a teacher implemented and the depth to which an individual teacher went with the provided materials. In terms of students' views, there were significant global changes in their views of their experience of the science classroom. However, there were some areas where no change or slightly negative changes of which some were expected and some were not. From these results, we comment on the necessity of sustained long-period implementations rather than single interventions, the requirement for similarly sustained professional development and the importance of monitoring the impact of inquiry-based implementations. This is especially important as inquiry-based approaches to science are required by many new curriculum reforms, most notably in this context, the new Australian curriculum currently being rolled out.

  16. Evaluating the implementation and impacts of middle grades inquiry-based engineering design modules

    Science.gov (United States)

    Harlan, Jessica M.

    This dissertation uses a format where I present and discuss three articles that were written in conjunction with my work on a research and evaluation team. The articles are based on a multi-year project researching and evaluating the design, development, and implementation of a middle grades integrated Science, Technology, Engineering, and Mathematics (STEM) program. Each of the articles demonstrates the complexity in researching and evaluating curricular development in multifaceted, rapidly changing environments. While the focus of each article differs, they all examine research and evaluation in the context of the design and development of middle grades engineering-design modules. The selected articles address challenges associated with assessing program objectives and evaluating program quality in complex education programs.The first article, presented in Chapter 2, provides an overview of the nature of the EYE program and examines the extent to which participation in the EYE program resulted in the achievement of program objectives. There is evidence that EYE Module participation has a positive impact on participating students as well as teachers. This study also revealed challenges associated with determining the impact of program participation simultaneously with program revisions and assessment development. The second article, presented in Chapter 3, examined the evaluation of fidelity of implementation of inquiry-oriented educational programs. This article was intended to examine one way of triangulating information to determine fidelity while considering variation in implementation consistent with program theories of learning. When applying this model to implementation of the EYE program, we found many teachers were implementing the modules with low to moderate fidelity, especially math teachers. The third article, presented in Chapter 4, examined the factor structure of an occupational values scale intended to measure student interest in STEM careers

    As efforts to develop new applications of engineered nanoscale materials (ENMs) continue to grow, so too has interest in the environmental, health, and safety (EHS) implications of these materials. However, thorough evaluation and interpretation of such implications could require substantial resources (e.g., estimated as >$120 million per year in federal funding 2013-2017). A structured, strategic approach for transparently planning research would support improved linkages between ENM research and risk assessments, and thereby enhance the utility of financial and other resources for EHS studies of ENMs. For this reason, we applied Comprehensive Environmental Assessment (CEA) as an approach to provide transparent input into research planning for 2 types of ENMs: nanoscale titanium dioxide and nanoscale silver. For each of these CEA applications, we employed a collective judgment method known as Nominal Group Technique (NGT) in 2 workshops sponsored by the US Environmental Protection Agency (USEPA). The objective of this paper is to present the outcomes of these CEA applications in the context of how our methodology can inform future efforts to identify collective goals in science (e.g., research priorities) through structured decision support approaches. Outcomes include clear lists of research priorities for each ENM developed through transparently engaging stakeholders having diverse technical and sector perspectives. In addition, we identified several procedural aspects that could be refined, including emphasizing breakout group interactions, identifying broad information priorities before more detailed research questions, and using rating rather than ranking prioritization methods. Beyond the research directions identified for specific ENMs, lessons learned about engaging stakeholders in research planning are expected to inform future research planning efforts for ENMs and other emerging materials across the scientific community.

    Ellwood, Robin B.

    This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged thirteen to fourteen years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on forty-six percent of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. This research also illustrates the positive gains in motivation and achievement outcomes that emerge from student experiences with extended time in isolated areas referred to

    2012-01-01

    Auditory-verbal short-term memory deficits (STM) are prevalent in aphasia and can contribute to sentence comprehension deficits. This study investigated the effectiveness of a novel STM treatment in improving STM (measured with span tasks) and sentence comprehension (measured with the Token Test and the Test for the Reception of Grammar, TROG) in a person with severe aphasia (transcortical motor). In particular, the research questions were: (1) Would STM training improve STM? (2) Would improvements from the STM training generalise to improvements in comprehension of sentences? STM was trained using listening span tasks of serial word recognition. No other language or sentence comprehension skills were trained. Following treatment, STM abilities improved (listening span, forward digit span). There was also evidence of generalisation to untreated sentence comprehension (only on the TROG). Backward digit span, phonological processing and single word comprehension did not improve. Improvements in sentence comprehension may have resulted from resilience to rapid decay of linguistic representations within sentences (words and phrases). This in turn facilitated comprehension.

    Full Text Available The purpose of this study was to investigate the effects of integrated information literacy in first-grade science curriculum on students’ science learning. In this quasi-experimental study, two first-grade classrooms from a public elementary school were randomly assigned into the experimental group and control group. The former accepted an inquiry-based science curriculum infused information literacy using the Super3 model, while the latter accepted the traditional lecture-oriented instruction. The instructional unit in both experimental and control groups was taught by the same science teacher and lasted around three weeks, seven periods of time per week. Two tests were designed to test student’s memory of factual information and comprehension of scientific concepts. Results from the analyses of covariance showed that the experimental group significantly outperformed their counterparts on two measures of science learning. It is suggested that integrated information literacy instruction could have a positive impact on first-graders’ subject content learning and lay a foundation for young children to be lifelong learners.

    We examined classrooms as complex systems that affect students' literacy learning through interacting effects of content and amount of time individual students spent in literacy instruction along with the global quality of the classroom-learning environment. We observed 27 third grade classrooms serving 315 target students using two different observation systems. The first assessed instruction at a more micro-level; specifically, the amount of time individual students spent in literacy instruction defined by the type of instruction, role of the teacher, and content. The second assessed the quality of the classroom-learning environment at a more macro level focusing on classroom organization, teacher responsiveness, and support for vocabulary and language. Results revealed that both global quality of the classroom learning environment and time individual students spent in specific types of literacy instruction covering specific content interacted to predict students' comprehension and vocabulary gains whereas neither system alone did. These findings support a dynamic systems model of how individual children learn in the context of classroom literacy instruction and the classroom-learning environment, which can help to improve observations systems, advance research, elevate teacher evaluation and professional development, and enhance student achievement.

    Transgenic Tg2576 mice overexpressing human amyloid precursor protein (hAPP) are a widely used Alzheimer's disease (AD) mouse model to evaluate treatment effects on amyloid beta (Aβ) pathology and cognition. Tg2576 mice on a B6;SJL background strain carry a recessive rd1 mutation that leads to early retinal degeneration and visual impairment in homozygous carriers. This can impair performance in behavioral tests that rely on visual cues, and thus, affect study results. Therefore, B6;SJL/Tg2576 mice were systematically backcrossed with 129S6/SvEvTac mice resulting in 129S6/Tg2576 mice that lack the rd1 mutation. 129S6/Tg2576 mice do not develop retinal degeneration but still show Aβ accumulation in the brain that is comparable to the original B6;SJL/Tg2576 mouse. However, comprehensive studies on cognitive decline in 129S6/Tg2576 mice are limited. In this study, we used two dementia mouse models on a 129S6 background--scopolamine-treated 129S6/SvEvTac mice (3-5 month-old) and transgenic 129S6/Tg2576 mice (11-13 month-old)-to establish a behavioral test battery for assessing learning and memory. The test battery consisted of five tests to evaluate different aspects of cognitive impairment: a Y-Maze forced alternation task, a novel object recognition test, the Morris water maze, the radial arm water maze, and a Y-maze spontaneous alternation task. We first established this behavioral test battery with the scopolamine-induced dementia model using 129S6/SvEvTac mice and then evaluated 129S6/Tg2576 mice using the same testing protocol. Both models showed distinctive patterns of cognitive impairment. Together, the non-invasive behavioral test battery presented here allows detecting cognitive impairment in scopolamine-treated 129S6/SvEvTac mice and in transgenic 129S6/Tg2576 mice. Due to the modular nature of this test battery, more behavioral tests, e.g. invasive assays to gain additional cognitive information, can easily be added.

    Most introductory geology courses include a lesson on the internal layered structure of the Earth. Due to the abstract nature of the content, this topic is difficult to teach using an inquiry-based approach. The challenge is two-fold: first, students cannot directly see the layers from their perspective on the earth's surface, and second, students have trouble grasping the vast scale of the earth, which far exceeds their everyday experiences. In addition, the two separate classification systems for dividing the internal structure of the Earth are often a point of confusion and source of misconceptions. In response to this challenge, we developed an inquiry lesson that scaffolds students' understanding of the compositional and rheological properties of the Earth's interior. The intent is to build students' understanding of the Earth's layers by guiding their attention to the reasons for the separate classification systems and the individual layers. The investigation includes teacher- or material-driven components such as guiding questions and specific hand-samples for analogues as well as student-driven components like collecting data and constructing explanations. The lesson opens with a series of questions designed to elicit students' existing ideas about the Earth's interior. The students are then guided to make observations of hand samples meant to represent examples of the crust and mantle as well as physical materials meant to serve as analogues for the lithosphere and asthenosphere. The lesson concludes with students integrating their observations into a model of the Earth's internal structure that accounts for both the compositional and rheological properties. Although this lesson was originally developed as a roughly 60 minute lesson for a class of 24 students, we also note ways this lesson can be modified for use at a variety of course levels. The lesson was pilot-tested in an introductory Earth Science course for future elementary (K-8) teachers. Data

    Estrada, Myrna Hipol

    In light of the need to close the achievement gap among our culturally and linguistically diverse students, more specifically the Hispanics and the Hispanic English Learners (ELs), the effects of teacher professional development (2 year PD vs. 1 Year PD vs. no PD) on the implementation of a standards-aligned and inquiry-based science curriculum program---the Integrated Coordinated Science for the 21st Century published by It's About Time, Inc. (ICS-IAT)---on the LAUSD ninth graders science scores were examined. Participants included 8,937 9th grade students (7,356 Hispanics). The primary outcome measurement was scaled scores from the California Standard Test (CST) in Integrated Coordinated Science (CST_ICS1). Correlations between California English Language Development Test (CELDT) component subscores (reading, listening and speaking) and CST scores were also examined. Results indicated that the science scores of the students of teachers who participated in two year PD were significantly higher compared to the scores of students of the one year PD group and the control group. The results show that all ethnic groups benefited from two years of teacher PD, except the African American group. Among Hispanics, students classified as IFEP, RFEP and EO gained from the teachers having two years of professional development. But the target population, ELs did not benefit from two years of teacher PD. The correlations between the CELDT and CST_ELA were much higher than the CELDT and CST_ICS1 correlations. This finding validates Abedi's claim (2004) that EL students are disadvantaged because of their language handicap on tests that have a greater language load. Two year PD participation significantly enhanced the accessibility of science to the ninth graders. The essential features in the PD were classroom simulation of all the activities identified in the storyboard with the actual and correct use of needed equipment and materials; creation and presentation of sample or model

    The present study investigates the need to include explicit attribution retraining in a program designed to teach reading comprehension strategies to children with learning disabilities (LD). The program had two versions: (a) self-regulation procedures and (b) self-regulation procedures plus explicit attributional retraining. Sixty children with LD were assigned to two training groups (with and without attributional retraining) and a control group. Twenty normally achieving students served as an additional control group. The effects were assessed via attribution measures and cognitive and metacognitive reading comprehension tests. Results indicated that children from both training groups improved on measures of cognitive strategies, but their gains were very low on metacognitive measures. In addition, regardless of training condition, students from both groups showed equally good attribution profiles.

    近年来,M—Learning系统已经作为技能训练和获取资源的一种新的方式.为了有效地对M.Learning系统进行评估,需要考虑系统的许多方面.目前,对M—Learning系统的评估通常采用层次分析法(Analytichierar.chyprocess,AHP).在采用AHP层次分析法进行评估时,常运用特征值的方法来确定因数的权重,而这种方法需进行一致性检验、计算量较大.文章给出了一种M—Learning系统新的综合评估法,该方法不需要进行一致性检验,且权化处理降低了确定因数权重的复杂度和计算量.在此基础上,还给出了一种应用综合评价函数的方法来对M—Learning系统进行评估.同时应用该文提出的方法对具体实例进行了评估,说明了此方法的有效性.%In recent years, the M-Learning system has emerged as a new manner of skill training and knowledge acquisition. To assess the M-Learning system effectively, various aspects of a M-Learning system must be taken into consideration. However, we usually utilize analytic hierarchy process (AHP) to evaluate the M-Learning system. In such assessments, the weights of indices were defined using the eigenvalue approach, but the eigen- value approach in the evaluation of the M-Learning system requires consistency test and complex calculations. Therefore, a new comprehensive evaluation method without using consistency check is introduced to the M- Learning system evaluation in this paper. Furthermore, weighting processing reduces the complexity and computational of determining the weights of indices. On this basis, this paper also presents a method using comprehensive evaluation function to evaluate the M-Learning system. An example is also provided to illustrate its effectiveness to the M-Learning system evaluation.

    中职学生不仅基础差,而且他们普遍认为读职业中专就是为了学习专门的技术,对物理等基础学科的学习不感兴趣,这种情况给物理的教学带来了新的挑战.传统的教学无法适应目前职业中专学校的物理教学,笔者通过多年的中职物理教学实践与总结,采用探究式教学,先创设情境,设计实验,学生收集证据,分析与讨论,得出结论.在实际教学中,探究式教学有效提高了我校学生学习物理的兴趣.%Most students in technical secondary school have some difficulties in study due to lack of motivation and poor basic knowledge. The purpose of study, they think, is to learn special techniques. The above situations lead to many chal-lenges and traditional methods are not suitable for physics teaching in technical secondary school. Therefore, we have been conducted practices of physics inquiry-based teaching for several years in our school. The process of inquiry teaching consists of several parts including creating environment, experimental design, collecting evidence, analysis, discussion and drawing conclusion. Thus, the class-teaching effects are improved and the students have more interests in learning physics.
