    Research in socioscientific issue (SSI)-based interventions is relatively new (Sadler in Journal of Research in Science Teaching 41:513-536, 2004; Zeidler et al. in Journal of Research in Science Teaching 46:74-101, 2009), and there is a need for understanding more about the effects of SSI-based learning environments (Sadler in Journal of Research in Science Teaching 41:513-536, 2004). Lee and Witz (International Journal of Science Education 31:931-960, 2009) highlighted the need for detailed case studies that would focus on how students respond to teachers' practices of teaching SSI. This study presents case studies that investigated the development of secondary school students' science understanding and their socioscientific reasoning within SSI-based learning environments. A multiple case study with embedded units of analysis was implemented for this research because of the contextual differences for each case. The findings of the study revealed that students' understanding of science, including scientific method, social and cultural influences on science, and scientific bias, was strongly influenced by their experiences in SSI-based learning environments. Furthermore, multidimensional SSI-based science classes resulted in students having multiple reasoning modes, such as ethical and economic reasoning, compared to data-driven SSI-based science classes. In addition to portraying how participants presented complexity, perspectives, inquiry, and skepticism as aspects of socioscientific reasoning (Sadler et al. in Research in Science Education 37:371-391, 2007), this study proposes the inclusion of three additional aspects for the socioscientific reasoning theoretical construct: (1) identification of social domains affecting the SSI, (2) using cost and benefit analysis for evaluation of claims, and (3) understanding that SSIs and scientific studies around them are context-bound.

    Studies have shown that a physician's clinical reasoning performance can be influenced by contextual factors. We explored how the clinical reasoning performance of medical students was impacted by contextual factors in order to expand upon previous findings in resident and board certified physicians. Using situated cognition as the theoretical framework, our aim was to evaluate the verbalized clinical reasoning processes of medical students in order to describe what impact the presence of contextual factors has on their reasoning performance. Seventeen medical student participants viewed three video recordings of clinical encounters portraying straightforward diagnostic cases in internal medicine with explicit contextual factors inserted. Participants completed a computerized post-encounter form as well as a think-aloud protocol. Three authors analyzed verbatim transcripts from the think-aloud protocols using a constant comparative approach. After iterative coding, utterances were analyzed and grouped into categories and themes. Six categories and ten associated themes emerged, which demonstrated overlap with findings from previous studies in resident and attending physicians. Four overlapping categories included emotional disturbances, behavioural inferences about the patient, doctor-patient relationship, and difficulty with closure. Two new categories emerged to include anchoring and misinterpretation of data. The presence of contextual factors appeared to impact clinical reasoning performance in medical students. The data suggest that a contextual factor can be innate to the clinical scenario, consistent with situated cognition theory. These findings build upon our understanding of clinical reasoning performance from both a theoretical and practical perspective.

    The purpose of this study was to determine if there are relationships among freshmen/first year students' reasoning abilities, conceptual understandings and problem-solving skills in introductory mechanics. The sample consisted of 165 freshmen science education prospective teachers (female = 86, male = 79; age range 17-21) who were enrolled in an introductory physics course. Data collection was done during the fall semesters in two successive years. At the beginning of each semester, the force concept inventory (FCI) and the classroom test of scientific reasoning (CTSR) were administered to assess students' initial understanding of basic concepts in mechanics and reasoning levels. After completing the course, the FCI and the mechanics baseline test (MBT) were administered. The results indicated that there was a significant difference in problem-solving skill test mean scores, as measured by the MBT, among concrete, formal and postformal reasoners. There were no significant differences in conceptual understanding levels of pre- and post-test mean scores, as measured by FCI, among the groups. The Benferroni post hoc comparison test revealed which set of reasoning levels showed significant difference for the MBT scores. No statistical difference between formal and postformal reasoners' mean scores was observed, while the mean scores between concrete and formal reasoners and concrete and postformal reasoners were statistically significantly different

    Wilhelm, Jennifer Anne

    This case study examined what student content understanding could occur in an inner city Industrial Electronics classroom located at Tree High School where project-based instruction, enhanced with technology, was implemented for the first time. Students participated in a project implementation unit involving sound waves and trigonometric reasoning. The unit was designed to foster common content learning (via benchmark lessons) by all students in the class, and to help students gain a deeper conceptual understanding of a sub-set of the larger content unit (via group project research). The objective goal of the implementation design unit was to have students gain conceptual understanding of sound waves, such as what actually waves in a wave, how waves interfere with one another, and what affects the speed of a wave. This design unit also intended for students to develop trigonometric reasoning associated with sinusoidal curves and superposition of sinusoidal waves. Project criteria within this design included implementation features, such as the need for the student to have a driving research question and focus, the need for benchmark lessons to help foster and scaffold content knowledge and understanding, and the need for project milestones to complete throughout the implementation unit to allow students the time for feedback and revision. The Industrial Electronics class at Tree High School consisted of nine students who met daily during double class periods giving 100 minutes of class time per day. The class teacher had been teaching for 18 years (mathematics, physics, and computer science). He had a background in engineering and experience teaching at the college level. Benchmark activities during implementation were used to scaffold fundamental ideas and terminology needed to investigate characteristics of sound and waves. Students participating in benchmark activities analyzed motion and musical waveforms using probeware, and explored wave phenomena using waves

    2010-01-01

    Dental educators complain that students struggle to apply what they have learnt theoretically in the clinical context. This paper is premised on the assumption that there is a relationship between conceptual thinking and clinical reasoning. The paper provides a theoretical framework for understanding the relationship between conceptual learning and clinical reasoning. A review of current literature is used to explain the way in which conceptual understanding influences clinical reasoning and the transfer of theoretical understandings to the clinical context. The paper argues that the connections made between concepts are what is significant about conceptual understanding. From this point of departure the paper describes teaching strategies that facilitate the kinds of learning opportunities that students need in order to develop conceptual understanding and to be able to transfer knowledge from theoretical to clinical contexts. Along with a variety of teaching strategies, the value of concept maps is discussed. The paper provides a framework for understanding the difficulties that students have in developing conceptual networks appropriate for later clinical reasoning. In explaining how students learn for clinical application, the paper provides a theoretical framework that can inform how dental educators facilitate the conceptual learning, and later clinical reasoning, of their students.

  15. Spatial Reasoning and Understanding the Particulate Nature of Matter: A Middle School Perspective

    Science.gov (United States)

    Cole, Merryn L.

    This dissertation employed a mixed-methods approach to examine the relationship between spatial reasoning ability and understanding of chemistry content for both middle school students and their science teachers. Spatial reasoning has been linked to success in learning STEM subjects (Wai, Lubinski, & Benbow, 2009). Previous studies have shown a correlation between understanding of chemistry content and spatial reasoning ability (e.g., Pribyl & Bodner, 1987; Wu & Shah, 2003: Stieff, 2013), raising the importance of developing the spatial reasoning ability of both teachers and students. Few studies examine middle school students' or in-service middle school teachers' understanding of chemistry concepts or its relation to spatial reasoning ability. The first paper in this dissertation addresses the quantitative relationship between mental rotation, a type of spatial reasoning ability, and understanding a fundamental concept in chemistry, the particulate nature of matter. The data showed a significant, positive correlation between scores on the Purdue Spatial Visualization Test of Rotations (PSVT; Bodner & Guay, 1997) and the Particulate Nature of Matter Assessment (ParNoMA; Yezierski, 2003) for middle school students prior to and after chemistry instruction. A significant difference in spatial ability among students choosing different answer choices on ParNoMA questions was also found. The second paper examined the ways in which students of different spatial abilities talked about matter and chemicals differently. Students with higher spatial ability tended to provide more of an explanation, though not necessarily in an articulate matter. In contrast, lower spatial ability students tended to use any keywords that seemed relevant, but provided little or no explanation. The third paper examined the relationship between mental reasoning and understanding chemistry for middle school science teachers. Similar to their students, a significant, positive correlation between

    Full Text Available According to previous research, students show difficulties in understanding photosynthesis and respiration, and basic ecological concepts like energy flow in ecosystems. There are successful teaching units accomplished in this area and many of them can be described as inquiry-based teaching. One definition of inquiry-based teaching is that it involves everything from finding problems, investigating them, debating with peers and trying to explain and give solutions. Accordingly students need to be confronted with challenging questions and empirical data to reason about and teachers need to implement student-generated inquiry discussion since students often stay silent and do not express their thoughts during science lessons. This thesis will focus on young peoples’ understanding of the functioning of plants, students’ participation during biology lessons, and how biology teaching is accomplished in primary and secondary school.Two school classroom projects focusing on teaching about plants and ecology are described. Four teachers and their 4th, 5th and 6th grade classes plus two science teachers and their three 8th grade classes collaborated. Photosynthesis and respiration were made concrete by using tasks where plants, plant cells, germs, seeds and the gas exchange were used. The aim was to listen to students’ reasoning in both teaching and interview situations. Learning outcome, as described by students’ reasoning in the classrooms and in individual interviews but also by their test results, is especially focused. Student-student and student-teacher interactions have been analysed with an ethnographic approach in the classroom context.The plant tasks encouraged the students’ in primary school to develop scientific reasoning and the interviews confirmed that the students had learned about photosynthesis. The ecology teaching in secondary school showed a substantial understanding confirmed both by students’ oral and written

    Keele Medical School's new curriculum includes a 5-week course to extend medical students' consultation skills beyond those historically required for competent inductive diagnosis. Clinical reasoning is a core skill for the practice of medicine, and is known to have implications for patient safety, yet historically it has not been explicitly taught. Rather, it has been assumed that these skills will be learned by accumulating a body of knowledge and by observing expert clinicians. This course aims to assist students to develop their own clinical reasoning skills and promote their greater understanding of, and potential to benefit from, the clinical reasoning skills of others. The course takes place in the fourth or penultimate year, and is integrated with students' clinical placements, giving them opportunities to practise and quickly embed their learning. This course emphasises that clinical reasoning extends beyond initial diagnosis into all other aspects of clinical practice, particularly clinical management. It offers students a variety of challenging and interesting opportunities to engage with clinical reasoning across a wide range of clinical practice. It addresses bias through metacognition and increased self-awareness, considers some of the complexities of prescribing and non-pharmacological interventions, and promotes pragmatic evidence-based practice, information management within the consultation and the maximising of patient adherence. This article describes clinical reasoning-based classroom and community teaching. Early evaluation suggests that students value the course and benefit from it. © 2013 John Wiley & Sons Ltd.

  18. Of Pigs and Men: Understanding Students' Reasoning About the Use of Pigs as Donors for Xenotransplantation

    Lindahl, Mats Gunnar

    2010-09-01

    Two important roles of education are to provide students with knowledge for their democratic participation in society and to provide knowledge for a future profession. In science education, students encounter values that may be in conflict with their worldview. Such conflicts may, for example, lead to constructive reflections as well as rejection of scientific knowledge and technology. Students’ ways of reasoning are important starting points for discussing problematic issues and may be crucial for constructive dialogues in the classroom. This study investigates students’ reasoning about conflicting values concerning the human-animal relationship exemplified by the use of genetically modified pigs as organ donors for xenotransplantation. Students’ reasoning is analyzed using Giddens’ concepts of disembedded and embedded practices in parallel with moral philosophical theories in a framework based on human-animal relationships. Thirteen students were interviewed and their stances categorized. Kantian deontological and classical utilitarian ethics were found within the patronage and the partnership models. These students appreciated expert knowledge but those using the partnership model could not accept xenotransplantation if pigs were to be killed. Students using care ethics did not appreciate expert knowledge since it threatened naturalness. The results suggest that stances against the use of scientific knowledge are more problematic than knowledge per se, and that conflicting stances have similarities that present opportunities for understanding and development of students’ argumentation skills for future participation in societal discourse on utilizing expert knowledge. Furthermore it is argued that science education could benefit from a higher awareness of the presence of different morals.

    The aim of this research was to explore the perceptions of undergraduate dental students regarding clinical reasoning skills and also discover the influences of different curriculum designs on the acquisition of these skills by students. Eighteen final-year students from three different dental schools with varied curricula and cultures participated in the current research. The research used qualitative methodology. The study took place in 2013-2014. Interviews captured the participants' own understanding of clinical reasoning and its acquisition plus they "talked through" a clinical problem using a "think-aloud" technique. Thematic analysis was used to analyse the transcripts of the recorded interviews. Results obtained were related to curriculum structure. Unfamiliarity with the term clinical reasoning was common in students. Students from different schools used different strategies to reason when discussing clinical vignettes. Clinical reasoning process was dominated by pattern recognition. Students' behaviours seemed to be influenced by cultural factors. This research contributes to a greater understanding of how students learn, understand and apply dental clinical reasoning which will improve educational practices in the future. © 2017 John Wiley & Sons A/S.

    2016-05-01

    Graduate nurses may have knowledge and adequate clinical psychomotor skills however they have been identified as lacking the clinical reasoning skills to deliver safe, effective care suggesting contemporary educational approaches do not always facilitate the development of nursing students' clinical reasoning. While nursing literature explicates the concept of clinical reasoning and develops models that demonstrate clinical reasoning, there is very little published about nursing students and clinical reasoning during clinical placements. Semi-structured interviews were conducted with ten clinical educators to gain an understanding of how they recognised, developed and appraised nursing students' clinical reasoning while on clinical placement. This study found variability in the clinical educators' conceptualisation, recognition, and facilitation of students' clinical reasoning. Although most of the clinical educators conceptualised clinical reasoning as a process those who did not demonstrated the greatest variability in the recognition and facilitation of students' clinical reasoning. The clinical educators in this study also described being unable to adequately appraise a student's clinical reasoning during clinical placement with the use of the current performance assessment tool.

    Full Text Available In this project, 10-12 year old students in three classes, investigated plant material to learn more about plants and photosynthesis. The research study was conducted to reveal the students’ scientific reasoning during their work. The eleven different tasks helped students investigate plant anatomy, plant physiology, and the gases involved in photosynthesis and respiration. The study was carried out in three ordinary classrooms. The collected data consisted of audio-taped discussions, students’ notebooks, and field notes. Students’ discussions and written work, during the different plant tasks, were analysed to see how the students’ learning and understanding processes developed. The analysis is descriptive and uses categories from a modified general typology of student’s epistemological reasoning. The study shows students’ level of interest in doing the tasks, their struggle with new words and concepts, and how they develop their knowledge about plant physiology. The study confirms thatstudents, in this age group, develop understanding and show an interest in complicated processes in natural science, e.g. photosynthesis.

    Establishing a strong foundation for the development of clinical reasoning in nursing students is essential to ensure safe and effective patient care. This study explored prelicensure baccalaureate nursing students' perceptions of their development of clinical reasoning, as well as their perceptions of how it is taught. In this phenomenological study, individual semistructured interviews were conducted to gather data related to participants' perceptions of their development of clinical reasoning. Data were analyzed using procedural steps delineated by Giorgi. Data analysis revealed three main themes: Instructor Characteristics, Importance of Clinical Reasoning, and Best Place to Learn Clinical Reasoning. Students recognized how clinical reasoning enhances safe and effective clinical practice and indicated the clinical arena was the most beneficial environment in which to learn clinical reasoning. Understanding students' perceptions of learning benefits nurse educators in planning nursing program curricula to enhance and facilitate the development of clinical reasoning.

    2012-01-01

    Good practice demands a clinical practice culture positively disposed to students with disabilities. Equality legislation seeks to protect those with a disability from either direct or indirect discrimination. The balance between providing "reasonable adjustments" for the student, whilst ensuring "Fitness to Practice", and ultimate employability, requires a close partnership between higher education and practice mentors. This paper reports on the development and evaluation of a range of interactive resources, used in the preparation of mentors to help them address the specific learning needs of disabled students. The evaluation revealed the benefit of student 'stories' in helping mentors to understand the support needs of disabled students and ensure reasonable adjustments are implemented in compliance with disability legislation. The interactive resources have been helpful in promoting positive action towards disabled students' learning, empathic understanding of mental health issues and knowledge and skills acquisition in support of dyslexic students. Implementing reasonable adjustments in practice requires a close working partnership between HEI's and mentors who appreciate support in understanding the development and application of coping strategies to overcome disabilities. Effective preparation of mentors is essential to ensure that opportunities for disabled students to succeed are maximised. Copyright © 2011. Published by Elsevier Ltd.

  11. Students' flexible use of ontologies and the value of tentative reasoning: Examples of conceptual understanding in three canonical topics of quantum mechanics

    Science.gov (United States)

    Hoehn, Jessica R.; Finkelstein, Noah D.

    2018-06-01

    As part of a research study on student reasoning in quantum mechanics, we examine students' use of ontologies, or the way students' categorically organize entities they are reasoning about. In analyzing three episodes of focus group discussions with modern physics students, we present evidence of the dynamic nature of ontologies, and refine prior theoretical frameworks for thinking about dynamic ontologies. We find that in a given reasoning episode ontologies can be dynamic in construction (referring to when the reasoner constructs the ontologies) or application (referring to which ontologies are applied in a given reasoning episode). In our data, we see instances of students flexibly switching back and forth between parallel stable structures as well as constructing and negotiating new ontologies in the moment. Methodologically, we use a collective conceptual blending framework as an analytic tool for capturing student reasoning in groups. In this research, we value the messiness of student reasoning and argue that reasoning in a tentative manner can be productive for students learning quantum mechanics. As such, we shift away from a binary view of student learning which sees students as either having the correct answer or not.

  12. Exploring students' patterns of reasoning

    Science.gov (United States)

    Matloob Haghanikar, Mojgan

    As part of a collaborative study of the science preparation of elementary school teachers, we investigated the quality of students' reasoning and explored the relationship between sophistication of reasoning and the degree to which the courses were considered inquiry oriented. To probe students' reasoning, we developed open-ended written content questions with the distinguishing feature of applying recently learned concepts in a new context. We devised a protocol for developing written content questions that provided a common structure for probing and classifying students' sophistication level of reasoning. In designing our protocol, we considered several distinct criteria, and classified students' responses based on their performance for each criterion. First, we classified concepts into three types: Descriptive, Hypothetical, and Theoretical and categorized the abstraction levels of the responses in terms of the types of concepts and the inter-relationship between the concepts. Second, we devised a rubric based on Bloom's revised taxonomy with seven traits (both knowledge types and cognitive processes) and a defined set of criteria to evaluate each trait. Along with analyzing students' reasoning, we visited universities and observed the courses in which the students were enrolled. We used the Reformed Teaching Observation Protocol (RTOP) to rank the courses with respect to characteristics that are valued for the inquiry courses. We conducted logistic regression for a sample of 18courses with about 900 students and reported the results for performing logistic regression to estimate the relationship between traits of reasoning and RTOP score. In addition, we analyzed conceptual structure of students' responses, based on conceptual classification schemes, and clustered students' responses into six categories. We derived regression model, to estimate the relationship between the sophistication of the categories of conceptual structure and RTOP scores. However, the

    Full Text Available Purpose: The purpose of this study is to investigate the reliability and validity of new clinical performance examination (CPX for assessing clinical reasoning skills and evaluating clinical reasoning ability of the students. Methods: Third-year medical school students (n=313 in Busan-Gyeongnam consortium in 2014 were included in the study. One of 12 stations was developed to assess clinical reasoning abilities. The scenario and checklists of the station were revised by six experts. Chief complaint of the case was rhinorrhea, accompanied by fever, headache, and vomiting. Checklists focused on identifying of the main problem and systematic approach to the problem. Students interviewed the patient and recorded subjective and objective findings, assessments, plans (SOAP note for 15 minutes. Two professors assessed students simultaneously. We performed statistical analysis on their scores and survey. Results: The Cronbach α of subject station was 0.878 and Cohen κ coefficient between graders was 0.785. Students agreed on CPX as an adequate tool to evaluate students’ performance, but some graders argued that the CPX failed to secure its validity due to their lack of understanding the case. One hundred eight students (34.5% identified essential problem early and only 58 (18.5% performed systematic history taking and physical examination. One hundred seventy-three of them (55.3% communicated correct diagnosis with the patient. Most of them had trouble in writing SOAP notes. Conclusion: To gain reliability and validity, interrater agreement should be secured. Students' clinical reasoning skills were not enough. Students need to be trained on problem identification, reasoning skills and accurate record-keeping.

    Full Text Available Understanding how different types of molecules move through cell membranes is a fundamental part of cell biology. To identify and address student misconceptions surrounding molecular movement through cell membranes, we surveyed student understanding on this topic using pre-class questions, in-class clicker questions, and subsequent exam questions in a large introductory biology course. Common misconceptions identified in student responses to the pre-class assessment questions were used to generate distractors for clicker questions. Two-tier diagnostic clicker questions were used to probe incoming common student misconceptions (first tier and their reasoning (second tier. Two subsequent lectures with assessment clicker questions were used to help students construct a new framework to understand molecular movement through cell membranes. Comparison of pre-assessment and post-assessment (exam performance showed dramatic improvement in students’ understanding of molecular movement: student answers to exam questions were 74.6% correct with correct reasoning while only 1.3% of the student answers were correct with correct reasoning on the pre-class assessment. Our results show that students’ conceptual understanding of molecular movement through cell membranes progressively increases through discussions of a series of clicker questions and suggest that this clicker-based teaching strategy was highly effective in correcting common student misconceptions on this topic.

  18. Evaluating Secondary Students' Scientific Reasoning in Genetics Using a Two-Tier Diagnostic Instrument

    2010-05-01

    While genetics has remained as one key topic in school science, it continues to be conceptually and linguistically difficult for students with the concomitant debates as to what should be taught in the age of biotechnology. This article documents the development and implementation of a two-tier multiple-choice instrument for diagnosing grades 10 and 12 students' understanding of genetics in terms of reasoning. The pretest and posttest forms of the diagnostic instrument were used alongside other methods in evaluating students' understanding of genetics in a case-based qualitative study on teaching and learning with multiple representations in three Western Australian secondary schools. Previous studies have shown that a two-tier diagnostic instrument is useful in probing students' understanding or misunderstanding of scientific concepts and ideas. The diagnostic instrument in this study was designed and then progressively refined, improved, and implemented to evaluate student understanding of genetics in three case schools. The final version of the instrument had Cronbach's alpha reliability of 0.75 and 0.64, respectively, for its pretest and the posttest forms when it was administered to a group of grade 12 students (n = 17). This two-tier diagnostic instrument complemented other qualitative data collection methods in this research in generating a more holistic picture of student conceptual learning of genetics in terms of scientific reasoning. Implications of the findings of this study using the diagnostic instrument are discussed.

    Collaborative reasoning occurs in clinical practice but is rarely developed during education. The computerized virtual patient (VP) cases allow for a stepwise exploration of cases and thus stimulate active learning. Peer settings during VP sessions are believed to have benefits in terms of reasoning but have received scant attention in the literature. The objective of this study was to thoroughly investigate interactions during medical students' clinical reasoning in two-party VP settings. An in-depth exploration of students' interactions in dyad settings of VP sessions was performed. For this purpose, two prerecorded VP sessions lasting 1 hour each were observed, transcribed in full, and analyzed. The transcriptions were analyzed using thematic analysis, and short clips from the videos were selected for subsequent analysis in relation to clinical reasoning and clinical aspects. Four categories of interactions were identified: (1) task-related dialogue, in which students negotiated a shared understanding of the task and strategies for information gathering; (2) case-related insights and perspectives were gained, and the students consolidated and applied preexisting biomedical knowledge into a clinical setting; (3) clinical reasoning interactions were made explicit. In these, hypotheses were followed up and clinical examples were used. The researchers observed interactions not only between students and the VP but also (4) interactions with other resources, such as textbooks. The interactions are discussed in relation to theories of clinical reasoning and peer learning. The dyad VP setting is conducive to activities that promote analytic clinical reasoning. In this setting, components such as peer interaction, access to different resources, and reduced time constraints provided a productive situation in which the students pursued different lines of reasoning. ©Samuel Edelbring, Ioannis Parodis, Ingrid E Lundberg.

  3. Students' reasons for preferring teleological explanations

    Science.gov (United States)

    Trommler, Friederike; Gresch, Helge; Hammann, Marcus

    2018-01-01

    The teleological bias, a major learning obstacle, involves explaining biological phenomena in terms of purposes and goals. To probe the teleological bias, researchers have used acceptance judgement tasks and preference judgement tasks. In the present study, such tasks were used with German high school students (N = 353) for 10 phenomena from human biology, that were explained both teleologically and causally. A sub-sample (n = 26) was interviewed about the reasons for their preferences. The results showed that the students favoured teleological explanations over causal explanations. Although the students explained their preference judgements etiologically (i.e. teleologically and causally), they also referred to a wide range of non-etiological criteria (i.e. familiarity, complexity, relevance and five more criteria). When elaborating on their preference for causal explanations, the students often focused not on the causality of the phenomenon, but on mechanisms whose complexity they found attractive. When explaining their preference for teleological explanations, they often focused not teleologically on purposes and goals, but rather on functions, which they found familiar and relevant. Generally, students' preference judgements rarely allowed for making inferences about causal reasoning and teleological reasoning, an issue that is controversial in the literature. Given that students were largely unaware of causality and teleology, their attention must be directed towards distinguishing between etiological and non-etiological reasoning. Implications for educational practice as well as for future research are discussed.

    Chan, Shiau Wei; Ismail, Zaleha; Sumintono, Bambang

    2016-01-01

    Based on a synthesis of literature, earlier studies, analyses and observations on high school students, this study developed an initial framework for assessing students' statistical reasoning about descriptive statistics. Framework descriptors were established across five levels of statistical reasoning and four key constructs. The former consisted of idiosyncratic reasoning, verbal reasoning, transitional reasoning, procedural reasoning, and integrated process reasoning. The latter include describing data, organizing and reducing data, representing data, and analyzing and interpreting data. In contrast to earlier studies, this initial framework formulated a complete and coherent statistical reasoning framework. A statistical reasoning assessment tool was then constructed from this initial framework. The tool was administered to 10 tenth-grade students in a task-based interview. The initial framework was refined, and the statistical reasoning assessment tool was revised. The ten students then participated in the second task-based interview, and the data obtained were used to validate the framework. The findings showed that the students' statistical reasoning levels were consistent across the four constructs, and this result confirmed the framework's cohesion. Developed to contribute to statistics education, this newly developed statistical reasoning framework provides a guide for planning learning goals and designing instruction and assessments.

  6. Student reasoning about electrostatic and gravitational potential energy: An exploratory study with interdisciplinary consequences

    Directory of Open Access Journals (Sweden)

    Beth A. Lindsey

    2014-01-01

    Full Text Available This paper describes an investigation into student reasoning about potential energy in the context of introductory electrostatics. Similar incorrect reasoning patterns emerged both in written questions administered after relevant instruction and in one-on-one interviews. These reasoning patterns are also prevalent in responses to questions posed about gravitational potential energy in the context of universal gravitation in introductory mechanics. This finding is relevant for interdisciplinary research, because many courses in multiple disciplines first introduce the concept of electric potential energy in analogy to gravitational potential energy. The results suggest that in introductory courses students do not gain an understanding of potential energy that is sufficiently robust to apply in more advanced physics courses or in disciplines other than physics, in which students must frequently reason with energy in the context of interactions between atoms and molecules.

    Franklin, Scott V.; Hermsen, Lisa M.

    2014-12-01

    We present a new approach to investigating student reasoning while writing: real-time capture of the dynamics of the writing process. Key-capture or video software is used to record the entire writing episode, including all pauses, deletions, insertions, and revisions. A succinct shorthand, "S notation," is used to highlight significant moments in the episode that may be indicative of shifts in understanding and can be used in followup interviews for triangulation. The methodology allows one to test the widespread belief that writing is a valuable pedagogical technique, which currently has little directly supportive research. To demonstrate the method, we present a case study of a writing episode. The data reveal an evolution of expression and articulation, discontinuous in both time and space. Distinct shifts in the tone and topic that follow long pauses and revisions are not restricted to the most recently written text. Real-time writing analysis, with its study of the temporal breaks and revision locations, can serve as a complementary tool to more traditional research methods (e.g., speak-aloud interviews) into student reasoning during the writing process.

  11. Arts, literature and reflective writing as educational strategies to promote narrative reasoning capabilities among physiotherapy students.

    2014-11-01

    The use of arts, literature and reflective writing has becoming increasingly popular in health professionals education. However, research examining its contribution as an educational strategy to promote narrative reasoning capabilities is limited, particularly from the students' perspective. This study aimed to explore the final year physiotherapy students' perspectives about the contribution of arts, literature and reflective writing in facilitating narrative reasoning capabilities. Three focus group meetings using a semi-structured interview schedule were carried out to collect data. Focus group sessions were audiotaped and transcribed verbatim. Interpretative phenomenological analysis was used to conduct the study and analyze the transcripts. Three themes emerged: (1) developmental understanding of the patients' experiences; (2) developmental understanding about the self; and (3) embedding reflection in clinical practice. Students emphasized an increasing capability to be sensitive and vicariously experience the patient's experience. Through reflective writing, students reported they became more capable of thinking critically about their practice and learning needs for continuous professional development. Finally, students highlighted the contribution of these strategies in making reflection part of their practice. Final year physiotherapy students reported enhanced skills of narrative reasoning. The findings support the inclusion of these strategies within the undergraduate physiotherapy curricula.

  12. From college to clinic: reasoning over memorization is key for understanding anatomy.

    2002-04-15

    Anatomy and physiology are taught in community colleges, liberal arts colleges, universities, and medical schools. The goals of the students vary, but educators in these diverse settings agree that success hinges on learning concepts rather than memorizing facts. In this article, educators from across the postsecondary educational spectrum expand on several points: (1) There is a problem with student perception that anatomy is endless memorization, whereas the ability to manage information and use reasoning to solve problems are ways that professionals work. This misperception causes students to approach the subject with the wrong attitude. (2) The process of learning to use information is as important as the concepts themselves. Using understanding to explain and make connections is a more useful long-term lesson than is memorization. Anatomy should be presented and learned as a dynamic basis for problem solving and for application in the practice and delivery of quality health care. (3) Integration of form and function must be explicit and universal across all systems. (4) Using only models, images, audiovisuals, or computers cannot lead students to the requisite reasoning that comes from investigative dissection of real tissue. (5) Some undergraduate courses require students to memorize excessive musculoskeletal detail. (6) Learning tissue biology is a particular struggle for medical students who have no background from an undergraduate course. (7) Medical professors and students see benefits when students have taken undergraduate courses in anatomy, histology, and physiology. If medical schools suggest these electives to applicants, medical students might arrive better prepared and, thus, be able to learn clinical correlations more efficiently in the limited allocated time of medical school curricula.

    2010-03-01

    Logical reasoning skills of students enrolled in General Chemistry at the University of Puerto Rico in Río Piedras were measured using the Group Assessment of Logical Thinking (GALT) test. The results were used to determine the students' cognitive level (concrete, transitional, formal) as well as their level of performance by logical reasoning mode (mass/volume conservation, proportional reasoning, correlational reasoning, experimental variable control, probabilistic reasoning and combinatorial reasoning). This information was used to identify particular deficiencies and gender effects, and to determine which logical reasoning modes were the best predictors of student performance in the general chemistry course. Statistical tests to analyze the relation between (a) operational level and final grade in both semesters of the course; (b) GALT test results and performance in the ACS General Chemistry Examination; and (c) operational level and student approach (algorithmic or conceptual) towards a test question that may be answered correctly using either strategy, were also performed.

    The purpose of this study is to reveal the development of knowledge of ordinary students to be like gifted students in the classroom based on Piaget's theory. In exposing it, students are given an open problem of classical analogy. Researchers explore students who conjecture via analogical reasoning in problem solving. Of the 32 students, through the method of think out loud and the interview was completed: 25 students conjecture via analogical reasoning. Of the 25 students, all of them have almost the same character in problem solving/knowledge construction. For that, a student is taken to analyze the thinking process while solving the problem/construction of knowledge based on Piaget's theory. Based on Piaget's theory in the development of the same knowledge, gifted students and ordinary students have similar structures in final equilibrium. They begin processing: assimilation and accommodation of problem, strategies, and relationships.

    2017-10-01

    Student engagement in learning science is both a desirable goal and a long-standing teacher challenge. Moving beyond engagement understood as transient topic interest, we argue that cognitive engagement entails sustained interaction in the processes of how knowledge claims are generated, judged, and shared in this subject. In this paper, we particularly focus on the initial claim-building aspect of this reasoning as a crucial phase in student engagement. In reviewing the literature on student reasoning and argumentation, we note that the well-established frameworks for claim-judging are not matched by accounts of creative reasoning in claim-building. We develop an exploratory framework to characterise and enact this reasoning to enhance engagement. We then apply this framework to interpret two lessons by two science teachers where they aimed to develop students' reasoning capabilities to support learning.

    It is a common educational practice for medical students to engage in case-based learning (CBL) exercises by working through clinical cases that have been developed by faculty. While such faculty-developed exercises have educational strengths, there are at least two major drawbacks to learning by this method: the number and diversity of cases is often limited; and students decrease their engagement with CBL cases as they grow accustomed to the teaching method. We sought to explore whether student case creation can address both of these limitations. We also compared student case creation to traditional clinical reasoning sessions in regard to tutorial group effectiveness, perceived gains in clinical reasoning, and quality of student-faculty interaction. Ten first-year medical students participated in a feasibility study wherein they worked in small groups to develop their own patient case around a preassigned diagnosis. Faculty provided feedback on case quality afterwards. Students completed pre- and post-self-assessment surveys. Students and faculty also participated in separate focus groups to compare their case creation experience to traditional CBL sessions. Students reported high levels of team engagement and peer learning, as well as increased ownership over case content and understanding of clinical reasoning nuances. However, students also reported decreases in student-faculty interaction and the use of visual aids ( P study suggest that student-generated cases can be a valuable adjunct to traditional clinical reasoning instruction by increasing content ownership, encouraging student-directed learning, and providing opportunities to explore clinical nuances. However, these gains may reduce student-faculty interaction. Future studies may be able to identify an improved model of faculty participation, the ideal timing for incorporation of this method in a medical curriculum, and a more rigorous assessment of the impact of student case creation on the

  4. Correlation, necessity, and sufficiency: Common errors in the scientific reasoning of undergraduate students for interpreting experiments.

    Coleman, Aaron B; Lam, Diane P; Soowal, Lara N

    2015-01-01

    Gaining an understanding of how science works is central to an undergraduate education in biology and biochemistry. The reasoning required to design or interpret experiments that ask specific questions does not come naturally, and is an essential part of the science process skills that must be learned for an understanding of how scientists conduct research. Gaps in these reasoning skills make it difficult for students to become proficient in reading primary scientific literature. In this study, we assessed the ability of students in an upper-division biochemistry laboratory class to use the concepts of correlation, necessity, and sufficiency in interpreting experiments presented in a format and context that is similar to what they would encounter when reading a journal article. The students were assessed before and after completion of a laboratory module where necessary vs. sufficient reasoning was used to design and interpret experiments. The assessment identified two types of errors that were commonly committed by students when interpreting experimental data. When presented with an experiment that only establishes a correlation between a potential intermediate and a known effect, students frequently interpreted the intermediate as being sufficient (causative) for the effect. Also, when presented with an experiment that tests only necessity for an intermediate, they frequently made unsupported conclusions about sufficiency, and vice versa. Completion of the laboratory module and instruction in necessary vs. sufficient reasoning showed some promise for addressing these common errors. © 2015 The International Union of Biochemistry and Molecular Biology.

    We discuss the implications of a framework to characterize student reasoning in an interview and its underpinnings in cognitive psychology. Our framework, described in a previous paper in these Proceedings, enables a researcher to identify various cognitive elements used by a student during an interview. Our thesis is that this framework can help identify reasoning paths used by the students. We discuss how this framework can be applied to both a coarse and fine grained analysis of reasoning and how it can be used to infer a student's implicit reasoning processes.

    Full Text Available This study focuses on students’ use of the mathematical concept of differentials in physics problem solving. For instance, in electrostatics, students need to set up an integral to find the electric field due to a charged bar, an activity that involves the application of mathematical differentials (e.g., dr, dq. In this paper we aim to explore students’ reasoning about the differential concept in physics problems. We conducted group teaching or learning interviews with 13 engineering students enrolled in a second-semester calculus-based physics course. We amalgamated two frameworks—the resources framework and the conceptual metaphor framework—to analyze students’ reasoning about differential concept. Categorizing the mathematical resources involved in students’ mathematical thinking in physics provides us deeper insights into how students use mathematics in physics. Identifying the conceptual metaphors in students’ discourse illustrates the role of concrete experiential notions in students’ construction of mathematical reasoning. These two frameworks serve different purposes, and we illustrate how they can be pieced together to provide a better understanding of students’ mathematical thinking in physics.

  8. Answer first: Applying the heuristic-analytic theory of reasoning to examine student intuitive thinking in the context of physics

    Full Text Available We have applied the heuristic-analytic theory of reasoning to interpret inconsistencies in student reasoning approaches to physics problems. This study was motivated by an emerging body of evidence that suggests that student conceptual and reasoning competence demonstrated on one task often fails to be exhibited on another. Indeed, even after instruction specifically designed to address student conceptual and reasoning difficulties identified by rigorous research, many undergraduate physics students fail to build reasoning chains from fundamental principles even though they possess the required knowledge and skills to do so. Instead, they often rely on a variety of intuitive reasoning strategies. In this study, we developed and employed a methodology that allowed for the disentanglement of student conceptual understanding and reasoning approaches through the use of sequences of related questions. We have shown that the heuristic-analytic theory of reasoning can be used to account for, in a mechanistic fashion, the observed inconsistencies in student responses. In particular, we found that students tended to apply their correct ideas in a selective manner that supported a specific and likely anticipated conclusion while neglecting to employ the same ideas to refute an erroneous intuitive conclusion. The observed reasoning patterns were consistent with the heuristic-analytic theory, according to which reasoners develop a “first-impression” mental model and then construct an argument in support of the answer suggested by this model. We discuss implications for instruction and argue that efforts to improve student metacognition, which serves to regulate the interaction between intuitive and analytical reasoning, is likely to lead to improved student reasoning.

    Feedback on clinical reasoning skills during fieldwork education is regarded as vital in occupational therapy students' professional development. The nature of supervisors' feedback however, could be confirmative and/or corrective and corrective feedback could be with or without suggestions on how to improve. The aim of the study was to evaluate the impact of supervisors' feedback on final-year occupational therapy students' clinical reasoning skills through comparing the nature of feedback with the students' subsequent clinical reasoning ability. A mixed-method approach with a convergent parallel design was used combining the collection and analysis of qualitative and quantitative data. From focus groups and interviews with students, data were collected and analysed qualitatively to determine how the students experienced the feedback they received from their supervisors. By quantitatively comparing the final practical exam grades with the nature of the feedback, their fieldwork End-of-Term grades and average academic performance it became possible to merge the results for comparison and interpretation. Students' clinical reasoning skills seem to be improved through corrective feedback if accompanied by suggestions on how to improve, irrespective of their average academic performance. Supervisors were inclined to underrate high performing students and overrate lower performing students. Students who obtained higher grades in the final practical examinations received more corrective feedback with suggestions on how to improve from their supervisors. Confirmative feedback alone may not be sufficient for improving the clinical reasoning skills of students. © 2015 The Authors.

    Prevention is better than cure. Public health plays an important role in promoting prevent medicine. To obtain the abilities to provide appropriate nursing services, learning public health is necessary for students who want to become registered nurses. When teachers teach public health to nursing students, it is important to motivate them to learn it. Therefore, we investigated the reasons for the lack of motivation to learn public health by conducting a questionnaire survey. The subjects were female nursing students in 29 vocational schools in Kanagawa and Chiba prefectures of Japan that allow graduation after a 3-year study period. We asked the students whether or not they had completed the subject of public health and analyzed those students who answered affirmatively. We analyzed 1,553 respondents whose average age was 22.6 ± 5.2 years (range, 18 to 45). Using factor analysis, we discovered the 5 reasons that lead to the lack of nursing students' motivation to learn public health: "Difficulties acquiring knowledge of public health," "Inappropriate attitudes of public health teachers," "Thinking lightly about the national examination in the field of public health," "Lack of understanding the importance of learning public health," and "Future plans that do not specialize in public health." Using multiple linear regression analysis, these 5 reasons were significant predictors for the lack of students' motivation. Older students also had significantly less motivation to learn public health than did younger students. When teachers instruct their students, they should teach public health better with the present knowledge.

    Scientific reasoning is an important component under the cognitive strand of the 21st century skills and is highly emphasized in the new science education standards. This study focuses on the assessment of student reasoning in control of variables (COV), which is a core sub-skill of scientific reasoning. The main research question is to investigate the extent to which the existence of experimental data in questions impacts student reasoning and performance. This study also explores the effects of task contexts on student reasoning as well as students' abilities to distinguish between testability and causal influences of variables in COV experiments. Data were collected with students from both USA and China. Students received randomly one of two test versions, one with experimental data and one without. The results show that students from both populations (1) perform better when experimental data are not provided, (2) perform better in physics contexts than in real-life contexts, and (3) students have a tendency to equate non-influential variables to non-testable variables. In addition, based on the analysis of both quantitative and qualitative data, a possible progression of developmental levels of student reasoning in control of variables is proposed, which can be used to inform future development of assessment and instruction.

  14. Students' Energy Understanding Across Biology, Chemistry, and Physics Contexts

    2017-07-01

    Energy is considered both as a disciplinary core idea and as a concept cutting across science disciplines. Most previous approaches studied progressing energy understanding in specific disciplinary contexts, while disregarding the relation of understanding across them. Hence, this study provides a systematic analysis of cross-disciplinary energy learning. On the basis of a cross-sectional study with n = 742 students from grades 6, 8, and 10, we analyze students' progression in understanding energy across biology, chemistry, and physics contexts. The study is guided by three hypothetical scenarios that describe how the connection between energy understanding in the three disciplinary contexts changes across grade levels. These scenarios are compared using confirmatory factor analysis (CFA). The results suggest that, from grade 6 to grade 10, energy understanding in the three disciplinary contexts is highly interrelated, thus indicating a parallel progression of energy understanding in the three disciplinary contexts. In our study, students from grade 6 onwards appeared to have few problems to apply one energy understanding across the three disciplinary contexts. These findings were unexpected, as previous research concluded that students likely face difficulties in connecting energy learning across disciplinary boundaries. Potential reasons for these results and the characteristics of the observed cross-disciplinary energy understanding are discussed in the light of earlier findings and implications for future research, and the teaching of energy as a core idea and a crosscutting concept are addressed.

  16. Assessing Student Peer Dialogue in Collaborative Settings: A Window into Student Reasoning

    Science.gov (United States)

    Stone, Antoinette

    The use of science classroom discourse analysis as a way to gain a better understanding of various student cognitive outcomes has a rich history in Science Education in general and Physics Education Research (PER) in particular. When students talk to each other in a collaborative peer instruction environment, such as in the CLASP classes (Collaborative Learning and Sense-making in Physics) at UC Davis, they get to practice and enhance their reasoning and sense-making skills, develop collaborative approaches to problem solving, and participate in co-construction of knowledge and shared thinking. To better understand these important cognitive processes, an analysis tool for monitoring, assessing and categorizing the peer talk arising in this environment is needed as a first step in teasing out evidence for these processes inherent in such talk. In order to meaningfully contribute to the extensive body of knowledge that currently exists, deeper, more insightful answers to the question of what happens linguistically when students struggle to "make sense" and how students use language to mediate these important cognitive outcomes is needed. To this end, a new tool for interpreting particularly qualitative linguistic data is needed, and the first part of the dissertation expounds on the development of a discourse analysis tool that has as its underpinnings a framework for coding borrowed extensively from Systemic Functional Linguistics Theory (SFL). The second part of this dissertation illustrates multiple ways in which the tool is used and how it can be utilized to address many current research questions.

    Full Text Available Ethical conflicts are ever more complex and require more interdisciplinary reflection to attain a solution. Bioethical reasoning can contribute to the understanding and eventual solution of many ethical conflicts in business. This study seeks to determine if a relationship exist among the social responsibility of business and the bioethical reasoning. A conceptual model using the multidimensional enterprise model proposed by Carroll (1979 and the bioethical principles proposed by Beauchamp and Childress (1979 is presented. A measurement instrument reliable for both constructs is developed. The results provide invaluable information that can help design new approaches for the ethical education of students.

    Emigh, Paul Jeffrey

    This dissertation describes research on student understanding of quantum mechanics across multiple levels of instruction. The primary focus has been to identify patterns in student reasoning related to key concepts in quantum mechanics. The specific topics include quantum measurements, time dependence, vector spaces, and angular momentum. The research has spanned a variety of different quantum courses intended for introductory physics students, upper-division physics majors, and graduate students in physics. The results of this research have been used to develop a set of curriculum, Tutorials in Physics: Quantum Mechanics, for addressing the most persistent student difficulties. We document both the development of this curriculum and how it has impacted and improved student understanding of quantum mechanics.

    2014-08-01

    According to national mathematics standards, algebra instruction should begin at kindergarten and continue through elementary school. Most often, teachers address algebra in the elementary grades with problems related to solving equations or understanding functions. With 789 2 nd - grade students, we administered (a) measures of calculations and word problems in the fall and (b) an assessment of pre-algebraic reasoning, with items that assessed solving equations and functions, in the spring. Based on the calculation and word-problem measures, we placed 148 students into 1 of 4 difficulty status categories: typically performing, calculation difficulty, word-problem difficulty, or difficulty with calculations and word problems. Analyses of variance were conducted on the 148 students; path analytic mediation analyses were conducted on the larger sample of 789 students. Across analyses, results corroborated the finding that word-problem difficulty is more strongly associated with difficulty with pre-algebraic reasoning. As an indicator of later algebra difficulty, word-problem difficulty may be a more useful predictor than calculation difficulty, and students with word-problem difficulty may require a different level of algebraic reasoning intervention than students with calculation difficulty.

    The training reference leading to the state nursing diploma places the learning of clinical reasoning at the center of the training. We have been wondering about the possibilities of making visible the student nurse's mental processes when they provide nursing care in order to identify their strategies and reasoning difficulties. It turns out that concept mapping is a research tool capable of showing these two aspects. The aim of this study is to verify a concept mapping made during an interview and built from the speech of a nursing student when analyzing a simulated clinical situation, is able to make visible its strategies clinical reasoning and reasoning difficulties. In a second phase of it, is to explore how the concept map once elaborated allows students to identify their own intellectual reasoning. 12 nursing second year students have participated in the study. Concept maps were constructed by the trainer/researcher as the students analyzed aloud a simulated clinical situation written. Concept maps were analyzed from a reference grid. Interviews were conducted following the elaboration of concept maps and student's comments were analyzed. Students reasoning strategies were either mixed inductive dominant (5/12) or hypothetical-deductive dominant (5/12). Reasoning difficulties identified are related to the lack of identification of important information, the lack of analysis of data, lack of connection or the existence of faulty links. Analysis of the comments highlights that concept mapping contributed to the development of metacognitive skills. The concept mapping has shown benefits in contributing to a diagnostic assessment of clinical reasoning learning. It is an additional resource tool to facilitate the development of metacognitive skills for students. This tool can be useful to implement support learning strategies in clinical reasoning.

    Medical students transitioning into professional practice feel underprepared to deal with the emotional complexities of real-life ethical situations. Simulation-based learning (SBL) may provide a safe environment for students to probe the boundaries of ethical encounters. Published studies of ethics simulation have not generated sufficiently deep accounts of student experience to inform pedagogy. The aim of this study was to understand students' lived experiences as they engaged with the emotional challenges of managing clinical ethical dilemmas within a SBL environment. This qualitative study was underpinned by an interpretivist epistemology. Eight senior medical students participated in an interprofessional ward-based SBL activity incorporating a series of ethically challenging encounters. Each student wore digital video glasses to capture point-of-view (PoV) film footage. Students were interviewed immediately after the simulation and the PoV footage played back to them. Interviews were transcribed verbatim. An interpretative phenomenological approach, using an established template analysis approach, was used to iteratively analyse the data. Four main themes emerged from the analysis: (1) 'Authentic on all levels?', (2)'Letting the emotions flow', (3) 'Ethical alarm bells' and (4) 'Voices of children and ghosts'. Students recognised many explicit ethical dilemmas during the SBL activity but had difficulty navigating more subtle ethical and professional boundaries. In emotionally complex situations, instances of moral compromise were observed (such as telling an untruth). Some participants felt unable to raise concerns or challenge unethical behaviour within the scenarios due to prior negative undergraduate experiences. This study provided deep insights into medical students' immersive and embodied experiences of ethical reasoning during an authentic SBL activity. By layering on the human dimensions of ethical decision-making, students can understand their

    2014-12-01

    Understanding how students use their conceptual models to reason about societal challenges involving societal issues such as natural hazard risk assessment, environmental policy and management, and energy resources can improve instructional activity design that directly impacts student motivation and literacy. To address this question, we created four laboratory exercises for an introductory physical geology course at Texas A&M University that engages students in authentic scientific practices by using real world problems and issues that affect societies based on the theory of situated cognition. Our case-study design allows us to investigate the various ways that students utilize model based reasoning to identify and propose solutions to societally relevant issues. In each of the four interventions, approximately 60 students in three sections of introductory physical geology were expected to represent and evaluate scientific data, make evidence-based claims about the data trends, use those claims to express conceptual models, and use their models to analyze societal challenges. Throughout each step of the laboratory exercise students were asked to justify their claims, models, and data representations using evidence and through the use of argumentation with peers. Cognitive apprenticeship was the foundation for instruction used to scaffold students so that in the first exercise they are given a partially completed model and in the last exercise students are asked to generate a conceptual model on their own. Student artifacts, including representation of earth systems, representation of scientific data, verbal and written explanations of models and scientific arguments, and written solutions to specific societal issues or environmental problems surrounding earth systems, were analyzed through the use of a rubric that modeled authentic expertise and students were sorted into three categories. Written artifacts were examined to identify student argumentation and

    2013-04-01

    The greenhouse effect is a reasonably complex scientific phenomenon which can be used as a model to examine students' conceptual understanding in science. Primary student-teachers' understanding of global environmental problems, such as climate change and ozone depletion, indicates that they have many misconceptions. The present mixed method study examines Finnish primary student-teachers' understanding of the greenhouse effect based on the results obtained via open-ended and closed-form questionnaires. The open-ended questionnaire considers primary student-teachers' spontaneous ideas about the greenhouse effect depicted by concept maps. The present study also uses statistical analysis to reveal respondents' conceptualization of the greenhouse effect. The concept maps and statistical analysis reveal that the primary student-teachers' factual knowledge and their conceptual understanding of the greenhouse effect are incomplete and even misleading. In the light of the results of the present study, proposals for modifying the instruction of climate change in science, especially in geography, are presented.

    Using a cooperative learning framework in a quantitative reasoning laboratory course, students were assigned to static teams of four in which they adopted roles that rotated regularly. The roles included: team leader, protocol manager, data recorder, and researcher. Using a mixed-methods approach, we investigated students' perceptions of the team roles and specifically addressed students' understanding of the roles, students' beliefs in their ability to enact the roles, and whether working with assigned team roles supported the teams to work effectively and cohesively. Although students expressed confidence in their understanding of the team roles, their understanding differed from the initial descriptions. This suggests that students' understanding of team roles may be influenced by a variety of factors, including their experiences within their teams. Students also reported that some roles appeared to lack a purpose, implying that for roles to be successful, they must have a clear purpose. Finally, the fact that many students reported ignoring the team roles suggests that students do not perceive roles as a requirement for team productivity and cohesion. On the basis of these findings, we provide recommendations for instructors wishing to establish a classroom group laboratory environment. PMID:29681667

    Vinten, Claire E K; Cobb, Kate A; Freeman, Sarah L; Mossop, Liz H

    Clinical reasoning is a fundamental skill for veterinary clinicians and a competency required of graduates by the Royal College of Veterinary Surgeons. However, it is unknown how veterinary students develop reasoning skills and where strengths and shortcomings of curricula lie. This research aimed to use the University of Nottingham School of Veterinary Medicine and Science (SVMS) as a case study to investigate the development of clinical reasoning among veterinary students. The analysis was framed in consideration of the taught, learned, and declared curricula. Sixteen staff and sixteen students from the SVMS participated separately in a total of four focus groups. In addition, five interviews were conducted with recent SVMS graduates. Audio transcriptions were used to conduct a thematic analysis. A content analysis was performed on all curriculum documentation. It was found that SVMS graduates feel they have a good level of reasoning ability, but they still experience a deficit in their reasoning capabilities when starting their first job. Overarching themes arising from the data suggest that a lack of responsibility for clinical decisions during the program and the embedded nature of the clinical reasoning skill within the curriculum could be restricting development. In addition, SVMS students would benefit from clinical reasoning training where factors influencing "real life" decisions (e.g., finances) are explored in more depth. Integrating these factors into the curriculum could lead to improved decision-making ability among SVMS graduates and better prepare students for the stressful transition to practice. These findings are likely to have implications for other veterinary curricula.

    Nurses are often faced with complex situations that made them to make ethical decisions; and to make such decisions, they need to possess the power of moral reasoning. Studies in Iran show that the majority of nursing students lack proper ethical development. Socratic teaching is a student-centered method which is strongly opposed to the lecturing method. This study was conducted to evaluate the impacts of Socratic questioning on the moral reasoning of the nursing students. In a quasi-experimental study, Crisham's Nursing Dilemma Test was used to evaluate the results of three groups before, immediately after, and 2 months after intervention. The data were analyzed using the SPSS statistical software (v 15). Participants and research context: Through random allocation, 103 nursing students were divided into three groups. In experiment group 1 (37 students), intervention consisted of Socratic questioning-based sessions on ethics and how to deal with moral dilemmas; experiment group 2 (33 students) attended a 4-h workshop; and the control group (33 students) was not subject to any interventions. Signed informed consent forms: This research was approved by the Ethics Committee of the University. All the participants signed written informed consents. There were significant differences between experiment group 1 and experiment group 2's pre-test and post-test scores on moral reasoning (p ≤ 0.001, p ≤ 0.001), nursing principled thinking (p ≤ 0.001, p ≤ 0.001), and practical considerations (p ≤ 0.001, p ≤ 0.031). Both the teaching approaches improved the subjects' moral reasoning; however, Socratic questioning proved more effective than lecturing. Compared to other similar studies in Iran and other countries, the students had inadequate moral reasoning competence. This study confirms the need for the development of an efficient course on ethics in the nursing curriculum. Also, it appears that Socratic questioning is an effective method to teach nursing ethics

  15. Empowering the crowd: faculty discourse strategies for facilitating student reasoning in large lecture

    2012-02-01

    Oregon State University (OSU) has restructured its introductory calculus-based sequence including reformed curriculum modeled after the Interactive Science Learning Environment (ISLE). ISLE is driven by an experimental cycle roughly summarized as: observe phenomena, find patterns and devise explanations, test explanations, develop a model, apply the model to new observations. In implementing ISLE at OSU we have chosen to focus on student scientific reasoning, specifically student ability to develop and test models, make explicit judgments on how to approach open-ended tasks, and take an authoritative role in knowledge development. In order to achieve these goals, the lecture course heavily utilizes social engagement. During large-lecture group work, emphasis is placed on facilitating student discourse about issues such as what systems to choose or how to define an open-ended problem. Instructional strategies are aimed at building off the group discourse to create a full-class community where knowledge is developed through collaboration with peers. We are achieving these goals along with an increase in measured student conceptual knowledge and traditional problem solving abilities, and no loss of content coverage. It is an ongoing effort to understand ``best'' instructional strategies and to facilitate new faculty when they teach the curriculum. Our research has focused on understanding how to facilitate activities that promote this form of discourse. We have quantitative analysis of engagement based on video data, qualitative analysis of dialogue from audio data, classroom observations by an external researcher, and survey data. In this session we share a subset of what we have learned about how to engage students in scientific reasoning discourse during large lecture, both at the group-work and full-class level.

    This paper gives a grounded cognition account of model-based learning of complex scientific knowledge related to socio-scientific issues, such as climate change. It draws on the results from a study of high school students learning about the carbon cycle through computational agent-based models and investigates two questions: First, how do students ground their understanding about the phenomenon when they learn and solve problems with computer models? Second, what are common sources of mistakes in students' reasoning with computer models? Results show that students ground their understanding in computer models in five ways: direct observation, straight abstraction, generalisation, conceptualisation, and extension. Students also incorporate into their reasoning their knowledge and experiences that extend beyond phenomena represented in the models, such as attitudes about unsustainable carbon emission rates, human agency, external events, and the nature of computational models. The most common difficulties of the students relate to seeing the modelled scientific phenomenon and connecting results from the observations with other experiences and understandings about the phenomenon in the outside world. An important contribution of this study is the constructed coding scheme for establishing different ways of grounding, which helps to understand some challenges that students encounter when they learn about complex phenomena with agent-based computer models.

    The purpose of this study is to describe the reasoning of students’ analogies in solving the broad concept problem in pyramids and prisms. This research method using descriptive qualitative. Data collection uses analogous reasoning tests and interviews. After that tested to 32 students of Junior High School. Based on the results of the analysis can be concluded that (1) 16% of students solve the problem of source and target problem correctly. (2) 29% of students correctly solve source problems and target problems incorrectly. (3) 55% solve source problems and target problems wrong. This is because students tend to memorize formulas not using analogy reasoning to solve new problems. Finally, the students have difficulties in solving new problems, because students are not accustomed to using the experience they have gained to solve new problems.

    A growing body of scholarly work indicates that student performance on physics problems stems from many factors, including relevant conceptual understanding. However, in contexts in which significant conceptual difficulties have been documented via research, it can be difficult to pinpoint and isolate such factors because students' written and interview responses rarely reveal the full richness of their conscious and, perhaps more importantly, subconscious reasoning paths. In this investigation, informed by dual-process theories of reasoning and decision making as well as the theoretical construct of accessibility, we conducted a series of experiments in order to gain greater insight into the factors impacting student performance on the "five-block problem," which has been used in the literature to probe student thinking about buoyancy. In particular, we examined both the impact of problem design (including salient features and cueing) and the impact of targeted instruction focused on density-based arguments for sinking and floating and on neutral buoyancy. The investigation found that instructional modifications designed to remove the strong intuitive appeal of the first-available response led to significantly improved performance, without improving student conceptual understanding of the requisite buoyancy concepts. As such, our findings represent an important first step in identifying systematic strategies for using theories from cognitive science to guide the development and refinement of research-based instructional materials.

    The goal of scientific literacy requires that students develop an understanding of the nature of science to assist them in the reasoned acquisition of science concepts and in their future role as citizens in a participatory democracy. The purpose of this study was to investigate and describe the range of positions that grade six students hold with respect to the nature of science and to investigate whether gender or prior science education was related to students' views of the nature of science. Two grade six classes participated in this study. One class was from a school involved in a long-term elementary science curriculum project. The science curriculum at this school involved constructivist epistemology and pedagogy and a realist ontology. The curriculum stressed hands-on, open-ended activities and the development of science process skills. Students were frequently involved in creating and testing explanations for physical phenomena. The second class was from a matched school that had a traditional science program. Results of the study indicated that students hold a wider range of views of the nature of science than previously documented. Student positions ranged from having almost no understanding of the nature of science to those expressing positions regarding the nature of science that were more developed than previous studies had documented. Despite the range of views documented, all subjects held realist views of scientific knowledge. Contrary to the literature, some students were able to evaluate a scientific theory in light of empirical evidence that they had generated. Results also indicated that students from the project school displayed more advanced views of the nature of science than their matched peers. However, not all students benefited equally from their experiences. No gender differences were found with respect to students' understanding of the nature of science.

    Given that current television programming contains numerous gambling portrayals, it is imperative to understand whether and to what extent these gambling behaviors in media influence individuals' beliefs, attitudes, and intentions. This study explores an extended model of the theory of reasoned action (TRA) by including gambling media exposure as a distal, mediating and mediated factor in predicting undergraduate students' intentions to gamble in a casino. Findings show that the extended model of TRA clearly indicates that the constructs of gambling media exposure, prior gambling experience, and level of gambling addiction contribute to the prediction of undergraduate students' casino gambling intentions. Theoretical implications of gambling media effects and practical implications for public policy are discussed, and future research directions are outlined.

    The highest movement in Semarang City is dominated by motorcycles, which reached 79% of the number of vehicles. Highest percentage movement use motorcycle caused the highest percentage accident by motorcycle users, which reached 66% and 9% involving high school students. This happens because of the dependence of motorcycles usage in fulfilling the needs of movement in the city of Semarang. Understanding student travel behavior based on their activities is used to know travel needs and the cause of dependence on motorcycle usage. Analysis method in this study use network analysis to compare the potential accessibility and actual accessibility to known why motorcycle chosen by students as the main mode. In addition, phenomenology analysis is used to explain the intent and reasons the data produced by network analysis. The analysis result indicates that the high use of motorcycles by high school students in the Semarang city due to the absence of other effective and efficient modes in fulfilling the movement needs. Even, the student which can potentially use public transport preferred to use a motorcycle. This mode is more effective and efficient because of its flexibility and lower costs.

    2015-09-01

    Full Text Available [This paper is part of the Focused Collection on Upper Division Physics Courses.] The time evolution of quantum states is arguably one of the more difficult ideas in quantum mechanics. In this article, we report on results from an investigation of student understanding of this topic after lecture instruction. We demonstrate specific problems that students have in applying time dependence to quantum systems and in recognizing the key role of the energy eigenbasis in determining the time dependence of wave functions. Through analysis of student responses to a set of four interrelated tasks, we categorize some of the difficulties that underlie common errors. The conceptual and reasoning difficulties that have been identified are illustrated through student responses to four sets of questions administered at different points in a junior-level course on quantum mechanics. Evidence is also given that the problems persist throughout undergraduate instruction and into the graduate level.

    Climate change is one of the most challenging problems facing today's global society (e.g., IPCC 2013). While climate change is a widely covered topic in the media, and abundant information is made available through the internet, the causes and consequences of climate change in its full complexity are difficult for individuals, especially non-scientists, to grasp. Science education is a field which can play a crucial role in fostering meaningful education of students to become climate literate citizens (e.g., NOAA 2009; Schreiner et al., 41, 3-50, 2005). If students are, at some point, to participate in societal discussions about the sustainable development of our planet, their learning with respect to such issues needs to be supported. This includes the ability to think critically, to cope with complex scientific evidence, which is often subject to ongoing inquiry, and to reach informed decisions on the basis of factual information as well as values-based considerations. The study presented in this paper focused on efforts to advance students in (1) their conceptual understanding about climate change and (2) their socioscientific reasoning and decision making regarding socioscientific issues in general. Although there is evidence that "knowledge" does not guarantee pro-environmental behavior (e.g. Schreiner et al., 41, 3-50, 2005; Skamp et al., 97(2), 191-217, 2013), conceptual, interdisciplinary understanding of climate change is an important prerequisite to change individuals' attitudes towards climate change and thus to eventually foster climate literate citizens (e.g., Clark et al. 2013). In order to foster conceptual understanding and socioscientific reasoning, a computer-based learning environment with an embedded concept mapping tool was utilized to support senior high school students' learning about climate change and possible solution strategies. The evaluation of the effect of different concept mapping scaffolds focused on the quality of student

    Full Text Available Reasoning abilities of the learners and its development was well-discussed in the world of education. The higher the ability of the person to reason abstractly, the higher the probability that a person will effectively function in the society. Thus, it is the main goal of the K-12 Curriculum of the Department of Education to improve the reasoning abilities and formal reasoning among students in the country. The higher the reasoning ability of a person, the more productive he is. The ability of logical reasoning has an essential function in the academic performance of students and their construction of the concepts. This study aimed to determine the logical reasoning abilities of 150 randomly selected junior high school students. Specifically, this study aimed to determine the logical reasoning abilities namely combinatorial reasoning, controlling variables, correlation reasoning, probabilistic reasoning and proportional reasoning among the grade 10 junior high school students and determine whether there is a significant difference in students’ logical reasoning abilities according to their gender. The respondents answered the Test of Logical Thinking (TOLT. Thirty respondents were interviewed to verify their answers. The findings of the study led to the following conclusions: most students correctly answered problems in probabilistic reasoning and least number of students correctly answered problems in proportional reasoning and combinatorial reasoning and, male and female respondents have equal performances in problems pertaining to combinatorial reasoning, controlling variables, correlational reasoning and probabilistic reasoning but female respondents are better in proportional reasoning than the male respondents.

    Alcohol use, reasons for use, and consequences of use continue to be a major concern in college student populations. This is especially true for students of legal drinking age who may experience different reasons for and greater negative consequences of alcohol use than students under 21 years old. Although multiple studies have used person-centered approaches to understand motivations for and ultimately prevent alcohol use, few have identified multiple typologies of reasons for alcohol use. The current study used latent class analysis to identify homogeneous subtypes of reasons for alcohol use and how classification was associated with alcohol-related consequences in college students aged 21 years old and older (N = 2300) from the 2013 Indiana College Substance Use Survey. Four profiles of reasons for alcohol use emerged across males and females: social drinkers, feel good drinkers, relaxed escaping drinkers, and emotion coping drinkers. Although the likelihood of consequences differed across gender, the emotion coping drinkers were more likely to experience all negative consequences, suggesting that it was a high-risk class. In general, this pattern of risk continued with the feel good drinkers and female relaxed escaping drinkers. These results can help optimize college substance use prevention and intervention efforts to (1) identify and understand characteristics of high- and low-risk student drinkers and (2) tailor the content of interventions to those specific profiles resulting in more effective approaches to reducing alcohol use.

    The demand and employment opportunities for geoscientists in the United States are projected to increase 23% from 2008 to 2018 (Gonzales, 2011). Despite this trend, there is a disconnect between undergraduate geoscience students and their desire to pursue geoscience careers. A theoretical framework was developed to understand the reasons why students decide to major in the geosciences and map those decisions to their career aspirations (Houlton, 2010). A modified critical incident study was conducted to develop the pathway model from 17, one-hour long semi-structured interviews of undergraduate geoscience majors from two Midwest Research Institutions (Houlton, 2010). Geoscience Academic Provenance maps geoscience students' initial interests, entry points into the major, critical incidents and future career goals as a pathway, which elucidates the relationships between each of these components. Analyses identified three geoscience student population groups that followed distinct pathways: Natives, Immigrants and Refugees. A follow up study was conducted in 2011 to ascertain whether these students continued on their predicted pathways, and if not, reasons for attrition. Geoscientists can use this framework as a guide to inform future recruitment and retention initiatives and target these geoscience population groups for specific employment sectors.

    Nonmedical use of prescription pain medications, sedatives, and stimulants is a well-documented problem among college students. Research has indicated that students who identify as lesbian, gay, or bisexual are at elevated risk. However, little is known about students' reasons for use. (1) To replicate findings that sexual minority students report higher nonmedical use than heterosexual students, moving from a campus-specific to a multicampus sample and (2) to test for an association between sexual orientation and reasons for use. The 2015 College Prescription Drug Study surveyed 3389 students from nine 4-year public and private colleges and universities across the United States using an anonymous online survey. Measures assessed demographic information, prevalence of nonmedical use, frequency of use, where the drugs were obtained, reasons for use, and consequences of use. Stepwise logistic regression models were used to determine if sexual orientation predicted use. Chi-square tests of independence were also used to analyze prevalence of use by demographics as well as to assess differences in reasons for use by sexual orientation. Sexual minority students were significantly more likely than heterosexual students to nonmedically use any prescription drug, pain medications, and sedatives. Sexual minority students were also more likely to select that they used pain medications to relieve anxiety, enhance social interactions, and to feel better. Conclusions/Importance: Although sexual minority students are more likely to report nonmedical use, students overall use prescription medications for similar reasons, with the exception of painkillers. Implications and areas for future research are discussed.

    schemas as a source of concept representation. A hermeneutical approach enabled us to access student meaning-making from students' verbal reports and gestures, to explore the mental imagery that lies in student explanations of basic principles in sequence stratigraphy. From the analysis of video-recorded interviews four main mental models were interpreted in gestures and verbal reports. The cognitive model known as container schema appeared to represent both spatially and temporally extended concepts differentiated into three separate sub-types. The source-path-goal schema was also common in student reasoning about sedimentary processes; specially dealing with deposition of sediment, the up-and-down schema, and the link schema were associated with responses about sea level fluctuations and unconformities. Results suggested that students tended to make more iconic and metaphoric gestures when dealing with abstract concepts such as relative sea level, base level, and unconformities. Based on the analysis of gestures that recreated certain patterns as time, strata, and sea-level fluctuations, we reasoned that proper representational gestures may indicate completeness in conceptual understanding. We concluded that students rely on image schemas to develop ideas about complex sedimentary processes. This research also supported the hypothesis that gestures provide an independent and non-linguistic indicator of image-schemas as mental models that shape conceptual development. Finally, we assessed the impact of using computer simulation to probe deeper understanding of specialized concepts in stratigraphy. Results suggested that when students are unfamiliar with concepts; students tend to convey meaning via gestures. Cognitive models were also identified in student interaction with the computer simulation and these mental models were interpreted from pointing gestures. We concluded that the impact of computers strive on fostering a sense of dynamism to their static and abstract

    2016-01-01

    Belief reasoning and emotion understanding were measured among 102 Mexican American bilingual children ranging from 4 to 7 years old. All children were tested in English and Spanish after ensuring minimum comprehension in each language. Belief reasoning was assessed using 2 false and 1 true belief tasks. Emotion understanding was measured using subtests from the Test for Emotion Comprehension. The influence of family background variables of yearly income, parental education level, and number of siblings on combined Spanish and English vocabulary, belief reasoning, and emotion understanding was assessed by regression analyses. Age and emotion understanding predicted belief reasoning. Vocabulary and belief reasoning predicted emotion understanding. When the sample was divided into language-dominant and balanced bilingual groups on the basis of language proficiency difference scores, there were no significant differences on belief reasoning or emotion understanding. Language groups were demographically similar with regard to child age, parental educational level, and family income. Results suggest Mexican American language-dominant and balanced bilinguals develop belief reasoning and emotion understanding similarly.

However, students also reported decreases in student–faculty interaction and the use of visual aids (P < 0.05. Conclusion: The results of our feasibility study suggest that student-generated cases can be a valuable adjunct to traditional clinical reasoning instruction by increasing content ownership, encouraging student-directed learning, and providing opportunities to explore clinical nuances. However, these gains may reduce student–faculty interaction. Future studies may be able to identify an improved model of faculty participation, the ideal timing for incorporation of this method in a medical curriculum, and a more rigorous assessment of the impact of student case creation on the development of clinical reasoning skills.

    2009-10-01

    Learning clinical reasoning is an important core activity of the modern dental curriculum. This article describes an intelligent tutoring system (ITS) for clinical reasoning skill acquisition. The system is designed to provide an experience that emulates that of live human-tutored problem-based learning (PBL) sessions as much as possible, while at the same time permitting the students to participate collaboratively from disparate locations. The system uses Bayesian networks to model individual student knowledge and activity, as well as that of the group. Tutoring algorithms use the models to generate tutoring hints. The system incorporates a multimodal interface that integrates text and graphics so as to provide a rich communication channel between the students and the system, as well as among students in the group. Comparison of learning outcomes shows that student clinical reasoning gains from the ITS are similar to those obtained from human-tutored sessions.

    HIV infection rates are rapidly increasing among young heterosexuals, making it increasingly important to understand how these individuals make decisions regarding risk in sexual encounters. Our objective in this study was to characterize young adults' safer sex behaviour and associate this behaviour with patterns of reasoning, using cognitive, information processing methods to understand the process of sexual risk taking. Sixty urban college students from NYC maintained diaries for two weeks and then were interviewed regarding lifetime condom use and sexual history. Using cognitive analysis, we characterized four patterns of condom use behaviour: consistent condom use (35.0%), inconsistent condom use (16.7%), shifting from consistent to inconsistent condom use (35.0%), and shifting from inconsistent to consistent condom use (13.3%). Directionality of reasoning (i.e. data-driven and hypothesis-driven reasoning) was analysed in the explanations provided for condom use decisions. The consistent and inconsistent patterns of condom use were associated with data-driven heuristic reasoning, where behaviour becomes automated and is associated with a high level of confidence in one's judgment. In the other two patterns, the shift in behaviour was due to a significant event that caused a change in type of reasoning to explanation-based reasoning, reflecting feelings of uncertainty and willingness to evaluate their decisions. We discuss these results within the framework of identifying potentially high-risk groups (e.g. heterosexual young adults) as well as intervention strategies for risk reduction. Further, our findings not only identify different patterns of condom use behaviour, but our investigation of the cognitive process of decision-making characterizes the conditions under which such behaviour and reasoning change.

    Our objective is to characterize and assess upper division and graduate student thinking by developing and testing an assessment tool for a physical hydrology class. The class' learning goals are: (1) Quantitative process-based understanding of hydrologic processes, (2) Experience with different methods in hydrology, (3) Learning, problem solving, communication skills. These goals were translated into two measurable tasks asked of students in a questionnaire: (1) Describe the significant processes in the hydrological cycle and (2) Describe laws governing these processes. A third question below assessed the students' ability to apply their knowledge: You have been hired as a consultant by __ to (1) assess how urbanization and the current drought have affected a local spring and (2) predict what the effects will be in the future if the drought continues. What information would you need to gather? What measurements would you make? What analyses would you perform? Student and expert responses to the questions were then used to develop a rubric to score responses. Using the rubric, 3 researchers independently blind-coded the full set of pre and post artifacts, resulting in 89% inter-rater agreement on the pre-tests and 83% agreement on the post-tests. We present student scores to illustrate the use of the rubric and to characterize student thinking prior to and following a traditional course. Most students interpreted Q1 in terms of physical processes affecting the water cycle, the primary organizing framework for hydrology, as intended. On the pre-test, one student scored 0, indicating no response, on this question. Twenty students scored 1, indicating rudimentary understanding, 2 students scored a 2, indicating a basic understanding, and no student scored a 3. Student scores on this question improved on the post-test. On the 22 post-tests that were blind scored, 11 students demonstrated some recognition of concepts, 9 students showed a basic understanding, and 2

    There is increasing evidence that students at different levels of training may benefit from different methods of learning clinical reasoning. Two of the common methods of teaching are the "whole - case" format and the "serial cue" approach. There is little empirical evidence to guide teachers as to which method to use and when to introduce them. We observed 23 students from different stages of training to examine how they were taking a history and how they were thinking whilst doing this. Each student interviewed a simulated patient who presented with a straightforward and a complex presentation. We inferred how students were reasoning from how they took a history and how they described their thinking while doing this. Early in their training students can only take a generic history. Only later in training are they able to take a focused history, remember the information they have gathered, use it to seek further specific information, compare and contrast possibilities and analyze their data as they are collecting it. Early in their training students are unable to analyze data during history taking. When they have started developing illness scripts, they are able to benefit from the "serial cue" approach of teaching clinical reasoning.

  8. Exploring students' understanding of reference frames and time in Galilean and special relativity

    2010-01-01

    This paper aims at exploring prospective physics teachers' reasoning associated with the concepts of reference frame, time and event which form the framework of the classical kinematics and that of the relativistic kinematics. About 100 prospective physics teachers were surveyed by means of a questionnaire involving classical kinematics situations and relativistic ones. The analysis of the answers shows a deep lack of understanding of both concepts of reference frame and event. Some students think that events may be simultaneous for an observer and not simultaneous for another one, even when both observers are located in the same reference frame. Most of the students surveyed cannot give an answer only depending on the location of the observer when his/her velocity is mentioned as if the movement contaminated the event. This lack of understanding is embodied in reasoning implemented by the population surveyed to address classical kinematics questions and seems to form a major obstacle to grasping relativistic kinematics.

    Electromagnetic induction is an important, yet complex, physics topic that is a part of Croatian high school curriculum. Nine Croatian high school students of different abilities in physics were interviewed using six demonstration experiments from electromagnetism (three of them concerned the topic of electromagnetic induction). Students were asked to observe, describe, and explain the experiments. The analysis of students' explanations indicated the existence of many conceptual and reasoning difficulties with the basic concepts of electromagnetism, and especially with recognizing and explaining the phenomenon of electromagnetic induction. Three student mental models of electromagnetic induction, formed during the interviews, which reoccurred among students, are described and analyzed within the knowledge-in-pieces framework.

    2017-11-01

    The internet has become a main source for health-related information retrieval. In addition to information published by medical experts, individuals share their personal experiences and narratives on blogs and social media platforms. Our increasing need to confront and make meaning of various sources and conflicting health information has challenged the way critical reasoning has become relevant in science education. This study addresses how the opportunities for students to develop and practice their capabilities to critically approach online health information can be created in science education. Together with two upper secondary biology teachers, we carried out a design-based study. The participating students were given an online retrieval task that included a search and evaluation of health-related online sources. After a few lessons, the students were introduced to an evaluation tool designed to support critical evaluation of health information online. Using qualitative content analysis, four themes could be discerned in the audio and video recordings of student interactions when engaging with the task. Each theme illustrates the different ways in which critical reasoning became practiced in the student groups. Without using the evaluation tool, the students struggled to overview the vast amount of information and negotiate trustworthiness. Guided by the evaluation tool, critical reasoning was practiced to handle source subjectivity and to sift out scientific information only. Rather than a generic skill and transferable across contexts, students' critical reasoning became conditioned by the multi-dimensional nature of health issues, the blend of various contexts and the shift of purpose constituted by the students.

    2015-12-01

    Traditional learning limits the potential for self-discovery, and the use of data and knowledge to understand Earth system relationships, processes, feedback mechanisms and system coupling. It is extremely difficult for undergraduate students to analyze, synthesize, and integrate quantitative information related to complex systems, as many concepts may not be mathematically tractable or yet to be formalized. Conceptual models have long served as a means for Earth scientists to organize their understanding of Earth's dynamics, and have served as a basis for human analytical reasoning and landscape interpretation. Consequently, we evaluated the use of conceptual modeling, knowledge representation and analytical reasoning to provide undergraduate students with an opportunity to develop and test geocomputational conceptual models based upon their understanding of Earth science concepts. This study describes the use of geospatial technologies and fuzzy cognitive maps to predict desertification across the South-Texas Sandsheet in an upper-level geomorphology course. Students developed conceptual models based on their understanding of aeolian processes from lectures, and then compared and evaluated their modeling results against an expert conceptual model and spatial predictions, and the observed distribution of dune activity in 2010. Students perceived that the analytical reasoning approach was significantly better for understanding desertification compared to traditional lecture, and promoted reflective learning, working with data, teamwork, student interaction, innovation, and creative thinking. Student evaluations support the notion that the adoption of knowledge representation and analytical reasoning in the classroom has the potential to transform undergraduate education by enabling students to formalize and test their conceptual understanding of Earth science. A model for developing and utilizing this geospatial technology approach in Earth science is presented.

    Tongnopparat, N.; Poonyawatpornkul, J.; Wattanakasiwich, P.

    This study aimed to investigate student reasoning about harmonic oscillations. We conducted a semi-structured interview based on three situations of harmonic motions—(1) a mass attaching to spring and horizontally oscillating without damping, (2) the same situation but vertically oscillating and (3) a mass attaching to spring and oscillating in viscous liquid. Forty-five second-year students taking a vibrations and wave course at Chiang Mai University, Thailand participated in a fifteen-minute interview, which was video-recorded. The videos were transcribed and analyzed by three physics instructors. As results, we found that most students had misconceptions about angular frequency and energy mostly in the second and third situations.

  17. Familial and individual reasons for student dropout: Schools’ perception

    2017-01-01

    Full Text Available The main objective of the research was to identify individual and familial factors students cite as the reasons for dropping out of school or being at the risk of doing so. We interviewed a total of twelve students who dropped out of school or are at the risk of dropping out of primary (six students or secondary school (six students and four parents. A semi-structured interview was used. We singled out four categories of students, determined by their perception of the reasons for dropping out of school. Those categories included: underage pregnancy, assuming a parental role, problematic behaviour (thefts, fights and weak motivation for school and learning. It seems justified to look for a typology of dropout cases since each of the selected groups of students requires specific preventive measures in order to secure continuation of their education. Furthermore, research has shown that, when it comes to their children dropping out of school, parents tend to blame the child’s character traits they deem unchangeable. The failure of school staff to help the child further encourages this belief in parents.

  18. Sixth-Grade Students' Progress in Understanding the Mechanisms of Global Climate Change

    Developing solutions for complex issues such as global climate change requires an understanding of the mechanisms involved. This study reports on the impact of a technology-enhanced unit designed to improve understanding of global climate change, its mechanisms, and their relationship to everyday energy use. Global Climate Change, implemented in the Web-based Inquiry Science Environment (WISE), engages sixth-grade students in conducting virtual investigations using NetLogo models to foster an understanding of core mechanisms including the greenhouse effect. Students then test how the greenhouse effect is enhanced by everyday energy use. This study draws on three data sources: (1) pre- and post-unit interviews, (2) analysis of embedded assessments following virtual investigations, and (3) contrasting cases of two students (normative vs. non-normative understanding of the greenhouse effect). Results show the value of using virtual investigations for teaching the mechanisms associated with global climate change. Interviews document that students hold a wide range of ideas about the mechanisms driving global climate change. Investigations with models help students use evidence-based reasoning to distinguish their ideas. Results show that understanding the greenhouse effect offers a foundation for building connections between everyday energy use and increases in global temperature. An impediment to establishing coherent understanding was the persistence of an alternative conception about ozone as an explanation for climate change. These findings illustrate the need for regular revision of curriculum based on classroom trials. We discuss key design features of models and instructional revisions that can transform the teaching and learning of global climate change.

    2012-02-01

    As part of a study of the science preparation of elementary school teachers, we investigated the quality of students' reasoning and explored the relationship between sophistication of reasoning and the degree to which the courses are considered inquiry oriented. First, we devised written content questions, which were open ended with the distinguishing feature of applying recently learned concepts in a new context. All the questions developed were based on a common template that required students to recognize and generalize the relevant facts or concepts and their interrelationships to suggest an applicable or plausible theory. To evaluate students' answers, we developed a rubric based on Bloom's taxonomy as revised and expanded by Anderson. Along with analyzing students' reasoning, we visited 20 universities and observed the courses in which the students were enrolled. We ranked the courses with respect to characteristics that are valued for the inquiry courses. With the large amount of collected data, we found that the likelihood of the higher cognitive processes are in favor of classes with higher measures of inquiry.

    2012-10-01

    Full Text Available The question ‘What constitutes African philosophy?’ was first raised with the publication of Placide Tempels’s seminal work Bantu philosophy in 1959. Tempels’s book inevitably elicited considerable critical response from African philosophers, which culminated in a wide range of publications such as Wiredu’s (1980 Philosophy and an African culture, Hountondji’s (1983 African philosophy: Myth and reality, Oruka’s (1990 Sage philosophy: Indigenous thinkers and modern debate on African philosophy, Shutte’s (1993 Philosophy for Africa, Masolo’s (1994 African philosophy in search of identity and Gyekye’s (1995 An essay of African philosophical thought: The Akan conceptual scheme. It has been over 60 years since the publication of Temples’s book and there continues to be serious debate about African philosophy. This article sought to contribute to the debate on the various conceptions of African philosophy, but with a focus on the challenges of teaching African philosophy to Philosophy of Education students at an open distance learning institution in South Africa. This article discussed the tendency amongst undergraduate Philosophy of Education students to conflate and reduce African philosophy to African cultures and traditions, and to the notion of ubuntu, and sought to understand the reasons for students’ inclination to treat African philosophy in this way. It examined students’ background knowledge of African philosophy, their critical thinking skills and whether their official study materials are selected and packaged in a manner that, in fact, adds to the challenges they face. Finally, the article explored the ways in which Philosophy of Education lecturers can adapt their pedagogy to provide students with a better understanding of African philosophy.

    Full Text Available ABSTRACT Introduction: Research in the field of medical reasoning has shed light on the reasoning process used by medical students. The strategies in this process are related to the analytical [hypothetical-deductive (HD] and nonanalytic [scheme-inductive (SI] systems, and pattern recognition (PR]. Objective: To explore the clinical reasoning process of students from the fifth year of medical school at the end of the clinical cycle of medical internship, and to identify the strategies used in preparing diagnostic hypotheses, knowledge organization and content. Method: Qualitative research conducted in 2014 at a Brazilian public university with medical interns. Following Stamm's method, a case in internal medicine (IM was built based on the theory of prototypes (Group 1 = 47 interns, in which the interns listed, according to their own perceptions, the signs, symptoms, syndromes, and diseases typical of internal medicine. This case was used for evaluating the clinical reasoning process of Group 2 (30 students = simple random sample obtained with the "think aloud" process. The verbalizations were transcribed and evaluated by Bardin's thematic analysis. The content analysis were approved by two experts at the beginning and at the end of the analysis process. Results: The interns developed 164 primary and secondary hypotheses when solving the case. The SI strategy prevailed with 48.8%, followed by PR (35.4%, HD (12.2%, and mixed (1.8 % each: SI + HD and HD + PR. The students built 146 distinct semantic axes, resulting in an average of 4.8/ participant. During the analysis, 438 interpretation processes were executed (average of 14.6/participant, and 124 combination processes (average of 4.1/participant. Conclusions: The nonanalytic strategies prevailed with the PR being the most used in the development of primary hypotheses (46.8% and the SI in secondary hypotheses (93%. The interns showed a strong semantic network and did three and a half times more

    Moral reasoning and reflective ability are important concepts in medical education. To date, the association between reflective ability and moral reasoning in medical students has not been measured. This study tested the hypotheses that, amongst final year medical students, (1) moral reasoning and reflective ability improve over time and (2) positive change in reflective ability favourably influences moral reasoning. With Institutional Ethical approval, 56 medical students (of a class of 110) participated fully both at the beginning and end of the final academic year. Reflective ability and moral reasoning were assessed at each time using Sobral's reflection-in-learning scale (RLS), Boenink's overall reflection score and by employing Kohlberg's schema for moral reasoning. The most important findings were that (1) Students' level of reflective ability scores related to medicine decreased significantly over the course of the year, (2) students demonstrated a predominantly conventional level of moral reasoning at both the beginning and end of the year, (3) moral reasoning scores tended to decrease over the course of the year and (4) RLS is a strong predictor of change in moral reasoning over time. This study confirms the usefulness of Sobral's RLS and BOR score for evaluating moral development in the context of medical education. This study further documents regression and levelling in the moral reasoning of final year medical students and a decrease in reflective ability applied in the medical context. Further studies are required to determine factors that would favourably influence reflective ability and moral reasoning among final year medical students.

    Clinical reasoning has been described as a process that draws heavily on the knowledge, skills and attributes that are particular to each health profession. However, the clinical reasoning processes of practitioners of different disciplines demonstrate many similarities, including hypothesis generation and reflective practice. The aim of this study was to understand clinical reasoning in osteopathy from the perspective of osteopathic clinical educators and the extent to which it was similar or different from clinical reasoning in other health professions. This study was informed by constructivist grounded theory. Participants were clinical educators in osteopathic teaching institutions in Australia, New Zealand and the UK. Focus groups and written critical reflections provided a rich data set. Data were analysed using constant comparison to develop inductive categories. According to participants, clinical reasoning in osteopathy is different from clinical reasoning in other health professions. Osteopaths use a two-phase approach: an initial biomedical screen for serious pathology, followed by use of osteopathic reasoning models that are based on the relationship between structure and function in the human body. Clinical reasoning in osteopathy was also described as occurring in a number of contexts (e.g. patient, practitioner and community) and drawing on a range of metaskills (e.g. hypothesis generation and reflexivity) that have been described in other health professions. The use of diagnostic reasoning models that are based on the relationship between structure and function in the human body differentiated clinical reasoning in osteopathy. These models were not used to name a medical condition but rather to guide the selection of treatment approaches. If confirmed by further research that clinical reasoning in osteopathy is distinct from clinical reasoning in other health professions, then osteopaths may have a unique perspective to bring to multidisciplinary

    2008-09-01

    In a recent article, Ates and Cataloglu (2007 Eur. J. Phys. 28 1161-71), in analysing results for a course in introductory mechanics for prospective science teachers, found no statistically significant correlation between students' pre-instruction scores on the Lawson classroom test of scientific reasoning ability (CTSR) and post-instruction scores on the force concept inventory (FCI). As a possible explanation, the authors suggest that the FCI does not probe for skills required to determine reasoning abilities. Our previously published research directly contradicts the authors' finding. We summarize our research and present a likely explanation for their observation of no correlation.

    Understanding the development of conditional (if-then) reasoning is critical for theoretical and educational reasons. Here we examined the hypothesis that there is a developmental transition between reasoning with true and contrary-to-fact (CF) causal conditionals. A total of 535 students between 11 and 14 years of age received priming conditions designed to encourage use of either a true or CF alternatives generation strategy and reasoning problems with true causal and CF causal premises (with counterbalanced order). Results show that priming had no effect on reasoning with true causal premises. By contrast, priming with CF alternatives significantly improved logical reasoning with CF premises. Analysis of the effect of order showed that reasoning with CF premises reduced logical responding among younger students but had no effect among older students. Results support the idea that there is a transition in the reasoning processes in this age range associated with the nature of the alternatives generation process required for logical reasoning with true and CF causal conditionals.

    2013-01-01

    Nurse educators can no longer focus on imparting to students knowledge that is merely factual and content specific. Activities that provide students with opportunities to apply concepts in real-world scenarios can be powerful tools. Nurse educators should take advantage of student-patient interactions to model clinical reasoning and allow students to practice complex decision making throughout the entire curriculum. In response to this change in nursing education, faculty in a pediatric course designed a reflective clinical reasoning activity based on the SAFETY template, which is derived from the National Council of State Boards of Nursing RN practice analysis. Students were able to prioritize key components of nursing care, as well as integrate practice issues such as delegation, Health Insurance Portability and Accountability Act violations, and questioning the accuracy of orders. SAFETY is proposed as a framework for integration of content knowledge, clinical reasoning, and reflection on authentic professional nursing concerns. Copyright 2012, SLACK Incorporated.

    2013-12-01

    We analyze the development in students’ understanding of fundamental principles in the context of learning a current interdisciplinary research topic—soft matter—that was adapted to the level of high school students. The topic was introduced in a program for interested 11th grade high school students majoring in chemistry and/or physics, in an off-school setting. Soft matter was presented in a gradual increase in the degree of complexity of the phenomena as well as in the level of the quantitative analysis. We describe the evolution in students’ use of fundamental thermodynamics principles to reason about phase separation—a phenomenon that is ubiquitous in soft matter. In particular, we examine the impact of the use of free energy analysis, a common approach in soft matter, on the understanding of the fundamental principles of thermodynamics. The study used diagnostic questions and classroom observations to gauge the student’s learning. In order to gain insight on the aspects that shape the understanding of the basic principles, we focus on the responses and explanations of two case-study students who represent two trends of evolution in conceptual understanding in the group. We analyze changes in the two case studies’ management of conceptual resources used in their analysis of phase separation, and suggest how their prior knowledge and epistemological framing (a combination of their personal tendencies and their prior exposure to different learning styles) affect their conceptual evolution. Finally, we propose strategies to improve the instruction of these concepts.

  15. An investigation of student understanding of classical ideas related to quantum mechanics: Potential energy diagrams and spatial probability density

    Science.gov (United States)

    Stephanik, Brian Michael

    This dissertation describes the results of two related investigations into introductory student understanding of ideas from classical physics that are key elements of quantum mechanics. One investigation probes the extent to which students are able to interpret and apply potential energy diagrams (i.e., graphs of potential energy versus position). The other probes the extent to which students are able to reason classically about probability and spatial probability density. The results of these investigations revealed significant conceptual and reasoning difficulties that students encounter with these topics. The findings guided the design of instructional materials to address the major problems. Results from post-instructional assessments are presented that illustrate the impact of the curricula on student learning.

  16. Case Studies of Secondary School Teachers Designing Socioscientific Issues-Based Instruction and Their Students' Socioscientific Reasoning

    Science.gov (United States)

    Karahan, Engin

    Addressing socioscientific issues (SSI) has been one of the main focuses in science education since the Science, Technology, and Society (STS) movement in the 1970s (Levinson, 2006); however, teaching controversial socioscientific issues has always been challenging for teachers (Dillon, 1994; Osborne, Duschl, & Fairbrother, 2002). Although teachers exhibit positive attitudes for using controversial socioscientific issues in their science classrooms, only a small percentage of them actually incorporate SSI content into their science curricula on a regular basis (Sadler, Amirshokoohi, Kazempour, & Allspaw, 2006; Lee & Witz, 2009). The literature in science education has highlighted the signi?cant relationships among teacher beliefs, teaching practices, and student learning (Bryan & Atwater, 2002; King, Shumow, & Lietz, 2001; Lederman, 1992). Despite the fact that the case studies present a relatively detailed picture of teachers' values and motivations for teaching SSI (e.g. Lee, 2006; Lee & Witz, 2009; Reis & Galvao, 2004), these studies still miss the practices of these teachers and potential outcomes for their students. Therefore, there is a great need for in-depth case studies that would focus on teachers' practices of designing and teaching SSI-based learning environments, their deeper beliefs and motivations for teaching SSI, and their students' response to these practices (Lee, 2006). This dissertation is structured as three separate, but related, studies about secondary school teachers' experiences of designing and teaching SSI-based classes and their students' understanding of science and SSI reasoning. The case studies in this dissertation seek answers for (1) teachers' practices of designing and teaching SSI-based instruction, as well as its relation to their deeper personal beliefs and motivations to teach SSI, and (2) how their students respond to their approaches of teaching SSI in terms of their science understanding and SSI reasoning.

    Full Text Available The lack of reasoning skills has been recognized as one of the contributing factors to the declined achievement in the Trends in Mathematics and Science Studies (TIMSS and Programme for International Student Assessment (PISA assessments in Malaysia. The use of socio-scientific issues (SSI as a learning strategy offers the potential of improving the level of students' reasoning skills and consequently improves students’ achievement in science subjects. This study examined the development of a measurement model of reasoning skills among science students based on SSI using the analysis of moment structure (AMOS approach before going to second level to full structured equation modelling (SEM. A total of 450 respondents were selected using a stratified random sampling. Results showed a modified measurement model of reasoning skills consisting of the View Knowledge (VK was as a main construct. The items that measure the level of pre-reflection of students fulfilled the elements of unidimensionality, validity, and reliability. Although the level of student reasoning skills was still low but this development of measurement model could be identified and proposed teaching methods that could be adopted to improve students’ reasoning skills.

    Linn, M. C.; Clement, C.; Pulos, S.; Sullivan, P.

    The mechanism linking instruction in scientific topics and instruction in logical reasoning strategies is not well understood. This study assesses the role of science topic instruction combined with logical reasoning strategy instruction in teaching adolescent students about blood pressure problems. Logical reasoning instruction for this study emphasizes the controlling-variables strategy. Science topic instruction emphasizes variables affecting blood pressure. Subjects receiving logical reasoning instruction link their knowledge of blood pressure variables to their knowledge of controlling variables more effectively than those receiving science topic instruction alone - their specific responses show how they attempt to integrate their understanding.Received: 15 April 1988

    Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws. High level science classes and participation in

  20. Students' understandings of electrochemistry

    O'Grady-Morris, Kathryn

    Electrochemistry is considered by students to be a difficult topic in chemistry. This research was a mixed methods study guided by the research question: At the end of a unit of study, what are students' understandings of electrochemistry? The framework of analysis used for the qualitative and quantitative data collected in this study was comprised of three categories: types of knowledge used in problem solving, levels of representation of knowledge in chemistry (macroscopic, symbolic, and particulate), and alternative conceptions. Although individually each of the three categories has been reported in previous studies, the contribution of this study is the inter-relationships among them. Semi-structured, task-based interviews were conducted while students were setting up and operating electrochemical cells in the laboratory, and a two-tiered, multiple-choice diagnostic instrument was designed to identify alternative conceptions that students held at the end of the unit. For familiar problems, those involving routine voltaic cells, students used a working-forwards problem-solving strategy, two or three levels of representation of knowledge during explanations, scored higher on both procedural and conceptual knowledge questions in the diagnostic instrument, and held fewer alternative conceptions related to the operation of these cells. For less familiar problems, those involving non-routine voltaic cells and electrolytic cells, students approached problem-solving with procedural knowledge, used only one level of representation of knowledge when explaining the operation of these cells, scored higher on procedural knowledge than conceptual knowledge questions in the diagnostic instrument, and held a greater number of alternative conceptions. Decision routines that involved memorized formulas and procedures were used to solve both quantitative and qualitative problems and the main source of alternative conceptions in this study was the overgeneralization of theory

    Developing critical-thinking and scientific reasoning skills are core learning objectives of science education, but little empirical evidence exists regarding the interrelationships between these constructs. Writing effectively fosters students' development of these constructs, and it offers a unique window into studying how they relate. In this study of undergraduate thesis writing in biology at two universities, we examine how scientific reasoning exhibited in writing (assessed using the Biology Thesis Assessment Protocol) relates to general and specific critical-thinking skills (assessed using the California Critical Thinking Skills Test), and we consider implications for instruction. We find that scientific reasoning in writing is strongly related to inference , while other aspects of science reasoning that emerge in writing (epistemological considerations, writing conventions, etc.) are not significantly related to critical-thinking skills. Science reasoning in writing is not merely a proxy for critical thinking. In linking features of students' writing to their critical-thinking skills, this study 1) provides a bridge to prior work suggesting that engagement in science writing enhances critical thinking and 2) serves as a foundational step for subsequently determining whether instruction focused explicitly on developing critical-thinking skills (particularly inference ) can actually improve students' scientific reasoning in their writing. © 2018 J.

    2015-04-01

    Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics. We describe a theoretical framework for understanding the patterns of student reasoning difficulties and how students develop expertise in quantum mechanics. The framework posits that the challenges many students face in developing expertise in quantum mechanics are analogous to the challenges introductory students face in developing expertise in introductory classical mechanics. This framework incorporates the effects of diversity in students' prior preparation, goals and motivation for taking upper-level physics courses in general as well as the ``paradigm shift'' from classical mechanics to quantum mechanics. The framework is based on empirical investigations demonstrating that the patterns of reasoning, problem-solving, and self-monitoring difficulties in quantum mechanics bear a striking resemblance to those found in introductory classical mechanics. Examples from research in quantum mechanics and introductory classical mechanics will be discussed to illustrate how the patterns of difficulties are analogous as students learn to unpack the respective principles and grasp the formalism in each knowledge domain during the development of expertise. Embracing such a theoretical framework and contemplating the parallels between the difficulties in these two knowledge domains can enable researchers to leverage the extensive literature for introductory physics education research to guide the design of teaching and learning tools for helping students develop expertise in quantum mechanics.

    [This paper is part of the Focused Collection on Upper Division Physics Courses.] Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics. Here, we describe a framework for understanding the patterns of student reasoning difficulties and how students develop expertise in quantum mechanics. The framework posits that the challenges many students face in developing expertise in quantum mechanics are analogous to the challenges introductory students face in developing expertise in introductory classical mechanics. This framework incorporates both the effects of diversity in upper-level students' prior preparation, goals, and motivation in general (i.e., the facts that even in upper-level courses, students may be inadequately prepared, have unclear goals, and have insufficient motivation to excel) as well as the "paradigm shift" from classical mechanics to quantum mechanics. The framework is based on empirical investigations demonstrating that the patterns of reasoning, problem-solving, and self-monitoring difficulties in quantum mechanics bear a striking resemblance to those found in introductory classical mechanics. Examples from research in quantum mechanics and introductory classical mechanics are discussed to illustrate how the patterns of difficulties are analogous as students learn to unpack the respective principles and grasp the formalism in each knowledge domain during the development of expertise.

    This study aims to explore the extent to which the use of analogy reasoning when students conduct conjecture in developing the scientific approach, so that the knowledge of the students can be used to build new knowledge. Analysis was conducted on student learning outcomes in Ciamis district. Based on these results, it was found the teacher not give an opportunity to the students to make conjecture on the students in problem solving as well as the construction of new knowledge. Moreover, teachers do not take advantage of analogical reasoning and scientific approach in constructing new knowledge.

    Clinical reasoning is an essential core competence for nurses. Maintaining quality of care and safety of patients results from cultivation of student's clinical reasoning competency. However, the concept of clinical reasoning in nursing students is complex and its meaning and process needs further clarification. The objectives were to explore the meaning of clinical reasoning competency in Taiwanese nursing students and to operationalize the concept in order to structure a framework illustrating the process of clinical reasoning. Thirteen seasoned nursing experts who had more than ten years of experience in nursing education or clinical practice participated in the interviews. The interviews were conducted in settings that the participants perceived as convenient, quiet and free of disturbance. Semi-structured interviews were conducted. The interviews were audio-recorded and field notes were taken. The data were analyzed using Waltz et al.'s (2010) method of content analysis. The data revealed four domains and 11 competency indicators. The four domains include: awareness of clinical cues, confirmation of clinical problems, determination and implementation of actions, and evaluation and self-reflection. Each domain comprises of 2-4 indicators of clinical reasoning competency. In addition, this study established a framework for cultivation of clinical reasoning competency in nursing students. The indicators of clinical reasoning competency in nursing students are interwoven, interactive and interdependent to form a dynamic process. The findings of this study may facilitate evaluation of nursing students' clinical reasoning competency and development of instruments to assess clinical reasoning in nursing students.

    Clinical reasoning is viewed as a problem-solving activity; in games, players solve problems. To provide excellent patient care, nursing students must gain competence in clinical reasoning. Utilising gaming elements and virtual simulations may enhance learning of clinical reasoning. To investigate nursing students' experiences of learning clinical reasoning process by playing a 3D simulation game. Cross-sectional descriptive study. Thirteen gaming sessions at two universities of applied sciences in Finland. The prototype of the simulation game used in this study was single-player in format. The game mechanics were built around the clinical reasoning process. Nursing students from the surgical nursing course of autumn 2014 (N=166). Data were collected by means of an online questionnaire. In terms of the clinical reasoning process, students learned how to take action and collect information but were less successful in learning to establish goals for patient care or to evaluate the effectiveness of interventions. Learning of the different phases of clinical reasoning process was strongly positively correlated. The students described that they learned mainly to apply theoretical knowledge while playing. The results show that those who played digital games daily or occasionally felt that they learned clinical reasoning by playing the game more than those who did not play at all. Nursing students' experiences of learning the clinical reasoning process by playing a 3D simulation game showed that such games can be used successfully for learning. To ensure that students follow a systematic approach, the game mechanics need to be built around the clinical reasoning process. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available A person is being bullied when he or she is exposed repeatedly and over time to negative actions on the part of one or more persons. Incidents of bullying are frequent occurrences for many children at school. This study was intended to investigate the perceptions of the elementary students about the reasons for bullying in the school. For this purpose 688 students from 4-8th. Grades of an elementary school were given a questionnaire “Colorado School Climate Survey”. The data was analyzed in terms of frequencies and percentiles. The results revealed that the most frequently reported reason was being physically weak (for bullies 56.5%, bullyvictims 52.9%, victims 48.6%, being fat (for victims bully-victims 45.1%, victims 42.6% and being poor (for bully-victims 43.2%, victims 41.5%, neither bully nor victims 39.4%. Almost half of the girls reported that the reasons of bullying are being short, being poor and being fat. Boys reported these reasons physical weakness, being fat and being skinny. According to neither bullies nor victims the reasons of bullying are physical weakness, poorness, and bad wearing. Victims also reported that first reason is physical weakness. Bullies reported that children without friends, short and poor children mostly bullied. Bully/victims again talked about physical weakness

  10. The Effect of Problem-Solving Video Games on the Science Reasoning Skills of College Students

    Fanetti, Tina M.

    As the world continues to rapidly change, students are faced with the need to develop flexible skills, such as science reasoning that will help them thrive in the new knowledge economy. Prensky (2001), Gee (2003), and Van Eck (2007) have all suggested that the way to engage learners and teach them the necessary skills is through digital games, but empirical studies focusing on popular games are scant. One way digital games, especially video games, could potentially be useful if there were a flexible and inexpensive method a student could use at their convenience to improve selected science reasoning skills. Problem-solving video games, which require the use of reasoning and problem solving to answer a variety of cognitive challenges could be a promising method to improve selected science reasoning skills. Using think-aloud protocols and interviews, a qualitative study was carried out with a small sample of college students to examine what impact two popular video games, Professor Layton and the Curious Village and Professor Layton and the Diabolical Box, had on specific science reasoning skills. The subject classified as an expert in both gaming and reasoning tended to use more higher order thinking and reasoning skills than the novice reasoners. Based on the assessments, the science reasoning of college students did not improve during the course of game play. Similar to earlier studies, students tended to use trial and error as their primary method of solving the various puzzles in the game and additionally did not recognize when to use the appropriate reasoning skill to solve a puzzle, such as proportional reasoning.

    2014-04-01

    The understanding of emotions based on counterfactual reasoning was studied in children with high-functioning autism spectrum disorders (n = 71) and in typically developing children (n = 71), aged 6-12 years. Children were presented with eight stories about two protagonists who experienced the same positive or negative outcome, either due to their own action or by default. Relative to the comparison group, children with high-functioning autism spectrum disorder were poor at explaining emotions based on downward counterfactual reasoning (i.e. contentment and relief). There were no group differences in upward counterfactual reasoning (i.e. disappointment and regret). In the comparison group, second-order false-belief reasoning was related to children's understanding of second-order counterfactual emotions (i.e. regret and relief), while children in the high-functioning autism spectrum disorder group relied more on their general intellectual skills. Results are discussed in terms of the different functions of counterfactual reasoning about emotion and the cognitive style of children with high-functioning autism spectrum disorder.

  12. Students who developed logical reasoning skills reported improved confidence in drug dose calculation: Feedback from remedial maths classes.

    The safe administration of drugs is a focus of attention in healthcare. It is regarded as acceptable that a formula card or mnemonic can be used to find the correct dose and fill a prescription even though this removes any requirement for performing the underlying computation. Feedback and discussion in class reveal that confidence in arithmetic skills can be low even when students are able to pass the end of semester drug calculation exam. To see if confidence in the understanding and performance of arithmetic for drug calculations can be increased by emphasising student's innate powers of logical reasoning after reflection. Remedial classes offered for students who have declared a dislike or lack of confidence in arithmetic have been developed from student feedback adopting a reasoning by logical step methodology. Students who gave up two hours of their free learning time were observed to engage seriously with the learning methods, focussing on the innate ability to perform logical reasoning necessary for drug calculation problems. Working in small groups allowed some discussion of the route to the answer and this was followed by class discussion and reflection. The results were recorded as weekly self-assessment scores for confidence in calculation. A self-selecting group who successfully completed the end of semester drug calculation exam reported low to moderate confidence in arithmetic. After four weeks focussing on logical skills a significant increase in self-belief was measured. This continued to rise in students who remained in the classes. Many students hold a negative belief regarding their own mathematical abilities. This restricts the learning of arithmetic skills making alternate routes using mnemonics and memorised steps an attractive alternative. Practising stepwise logical reasoning skills consolidated by personal reflection has been effective in developing student's confidence and awareness of their innate powers of deduction supporting an

    This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students.

    Clinical reasoning is a necessary skill for medical students to acquire in the course of their education, and there is evidence that they can start this process at the undergraduate level. However, physician educators who are experts in their given fields may have difficulty conveying their complex thought processes to students. Providing faculty development that equips educators with tools to teach clinical reasoning may support skill development in early medical students. We provided faculty development on a modified Bayesian method of teaching clinical reasoning to clinician educators who facilitated small-group, case-based workshops with 2nd-year medical students. We interviewed them before and after the module regarding their perceptions on teaching clinical reasoning. We solicited feedback from the students about the effectiveness of the method in developing their clinical reasoning skills. We carried out this project during an institutional curriculum rebuild where clinical reasoning was a defined goal. At the time of the intervention, there was also increased involvement of the Teaching and Learning Center in elevating the status of teaching and learning. There was high overall satisfaction with the faculty development program. Both the faculty and the students described the modified Bayesian approach as effective in fostering the development of clinical reasoning skills. Through this work, we learned how to form a beneficial partnership between a clinician educator and Teaching and Learning Center to promote faculty development on a clinical reasoning teaching method for early medical students. We uncovered challenges faced by both faculty and early learners in this study. We observed that our faculty chose to utilize the method of teaching clinical reasoning in a variety of manners in the classroom. Despite obstacles and differing approaches utilized, we believe that this model can be emulated at other institutions to foster the development of clinical

    Problem-based learning is an educational method promoting clinical reasoning that has been implemented in many fields of health education. Questioning is a learning strategy often employed in problem-based learning sessions. To explore what is known about the influence of questioning on the promotion of clinical reasoning of students in health care education, specifically in the field of nursing and using the educational method of problem-based learning. A scoping review following Arksey and O'Malley's five stages was conducted. The CINAHL, EMBASE, ERIC, Medline, and PubMed databases were searched for articles published between the years of 2000 and 2017. Each article was summarized and analyzed using a data extraction sheet in relation to its purpose, population group, setting, methods, and results. A descriptive explication of the studies based on an inductive analysis of their findings to address the aim of the review was made. Nineteen studies were included in the analysis. The studies explored the influence of questioning on critical thinking rather than on clinical reasoning. The nature of the questions asked and the effect of higher-order questions on critical thinking were the most commonly occurring themes. Few studies addressed the use of questioning in problem-based learning. More empirical evidence is needed to gain a better understanding of the benefit of questioning in problem-based learning to promote students' clinical reasoning. Copyright © 2018 Elsevier Ltd.

The result of this study includes: (1) The enhancement of the mathematical analogical reasoning ability of the students who gets the learning of concept attainment model is better than the enhancement of the mathematical analogical reasoning ability of the students who gets the conventional learning as a whole and based on PMK; (2) There is no interaction between the learning that is used and PMK on enhancing mathematical analogical reasoning ability.

  1. Documenting the use of expert scientific reasoning processes by high school physics students

    2010-11-01

    Full Text Available We describe a methodology for identifying evidence for the use of three types of scientific reasoning. In two case studies of high school physics classes, we used this methodology to identify multiple instances of students using analogies, extreme cases, and Gedanken experiments. Previous case studies of expert scientists have indicated that these processes can be central during scientific model construction; here we code for their spontaneous use by students. We document evidence for numerous instances of these forms of reasoning in these classes. Most of these instances were associated with motion- and force-indicating depictive gestures, which we take as one kind of evidence for the use of animated mental imagery. Altogether, this methodology shows promise for use in highlighting the role of nonformal reasoning in student learning and for investigating the possible association of animated mental imagery with scientific reasoning processes.

    Objective: The aim of this research was to obtain the views of young children regarding their reasons for rejecting a peer. Method: To achieve this goal, we conducted a qualitative study in the context of theory building research using an analysis methodology based on Grounded Theory. The collected information was extracted through semi-structured individual interviews from a sample of 853 children aged 6 from 13 urban public schools in Spain. Results: The children provided 3,009 rejection nominations and 2,934 reasons for disliking the rejected peers. Seven reason categories emerged from the analysis. Four categories refer to behaviors of the rejected children that have a cost for individual peers or peer group such as: direct aggression, disturbance of wellbeing, problematic social and school behaviors and dominance behaviors. A further two categories refer to the identities arising from the preferences and choices of rejected and rejecter children and their peers: personal identity expressed through preferences and disliking, and social identity expressed through outgroup prejudices. The "no-behavior or no-choice" reasons were covered by one category, unfamiliarity. In addition, three context categories were found indicating the participants (interpersonal-group), the impact (low-high), and the subjectivity (subjective-objective) of the reason. Conclusion: This study provides researchers and practitioners with a comprehensive taxonomy of reasons for rejection that contributes to enrich the theoretical knowledge and improve interventions for preventing and reducing peer rejection.

    Clinical reasoning process leads clinician to get purposeful steps from signs and symptoms toward diagnosis and treatment. This research intends to investigate the effect of teaching clinical reasoning on problem-solving skills of medical students. This research is a semi-experimental study. Nineteen Medical student of the pediatric ward as case group participated in a two-day workshop for training clinical reasoning. Before the workshop, they filled out Diagnostic Thinking Inventory (DTI) questionnaires. Fifteen days after the workshop the DTI questionnaire completed and "key feature" (KF) test and "clinical reasoning problem" (CRP) test was held. 23 Medical student as the control group, without passing the clinical reasoning workshop DTI questionnaire completed, and KF test and CRP test was held. The average score of the DTI questionnaire in the control group was 162.04 and in the case group before the workshop was 153.26 and after the workshop was 181.68. Compare the average score of the DTI questionnaire before and after the workshop there is a significant difference. The difference between average KF test scores in the control and the case group was not significant but between average CRP test scores was significant. Clinical reasoning workshop is effectiveness in promoting problem-solving skills of students.

    Students' epistemological views about biology--their ideas about what "counts" as learning and understanding biology--play a role in how they approach their courses and respond to reforms. As introductory biology courses incorporate more physics and quantitative reasoning, student attitudes about the role of equations in biology become especially relevant. However, as documented in research in physics education, students' epistemologies are not always stable and fixed entities; they can be dynamic and context-dependent. In this paper, we examine an interview with an introductory student in which she discusses the use of equations in her reformed biology course. In one part of the interview, she expresses what sounds like an entrenched negative stance toward the role equations can play in understanding biology. However, later in the interview, when discussing a different biology topic, she takes a more positive stance toward the value of equations. These results highlight how a given student can have diverse ways of thinking about the value of bringing physics and math into biology. By highlighting how attitudes can shift in response to different tasks, instructional environments, and contextual cues, we emphasize the need to attend to these factors, rather than treating students' beliefs as fixed and stable.

    Structured problem-solving lessons are used to explore mathematical concepts such as pattern and relationships in early algebra, and regularly used in Japanese Lesson Study research lessons. However, enactment of structured problem-solving lessons which involves detailed planning, anticipation of student solutions and orchestration of whole-class discussion of solutions is an ongoing challenge for many teachers. Moreover, primary teachers have limited experience in teaching early algebra or mathematical reasoning actions such as generalising. In this study, the critical factors of enacting the structured problem-solving lessons used in Japanese Lesson Study to elicit and develop primary students' capacity to generalise are explored. Teachers from three primary schools participated in two Japanese Lesson Study teams for this study. The lesson plans and video recordings of teaching and post-lesson discussion of the two research lessons along with students' responses and learning are compared to identify critical factors. The anticipation of students' reasoning together with preparation of supporting and challenging prompts was critical for scaffolding students' capacity to grasp and communicate generality.

    Negative numbers are among the first formalizations students encounter in their mathematics learning that clearly differ from out-of-school experiences. What has not sufficiently been addressed in previous research is the question of how students draw on their prior experiences when reasoning on negative numbers and how they infer from these experiences. This article presents results from an empirical study investigating sixth-grade students' reasoning and inferring from school-based and out-of-school experiences. In particular, it addresses the order relation, which deals with students' very first encounters with negative numbers. Here, students can reason in different ways, depending on the experiences they draw on. We study how students reason before a lesson series and how their reasoning is influenced through this lesson series where the number line and the context debts-and-assets are predominant. For grasping the reasoning's inferential and social nature and conducting in-depth analyses of two students' reasoning, we use an epistemological framework that is based on the philosophical theory of inferentialism. The results illustrate how the students infer their reasoning from out-of-school and from school-based experiences both before and after the lesson series. They reveal interesting phenomena not previously analyzed in the research on the order relation for integers.

    This cross-sectional questionnaire survey assessed the motives for choosing dentist as a profession among dentistry students at Damascus University, Syrian Arab Republic. A total of 408 undergraduate students (233 males and 175 females) aged 18-23 years were selected randomly from students in the second, third and fourth years of dentistry study. They completed a questionnaire that enquired about their reasons for studying dentistry as well as their sociodemographic characteristics. The number of admissions in females had increased over the 3 years. Most parents of the students were university-educated. The main motivation for choosing dentistry was as a means to achieve personal goals, including getting a good job abroad, having financial independence, and attaining a good reputation. There were significant differences between the sexes with regard to the reasons for choosing dentistry.

    2013-10-01

    This study aims to provide insights into the role of learners' knowledge structures about a socio-scientific issue (SSI) in their informal reasoning on the issue. A total of 42 non-science major university students' knowledge structures and informal reasoning were assessed with multidimensional analyses. With both qualitative and quantitative analyses, this study revealed that those students with more extended and better-organized knowledge structures, as well as those who more frequently used higher-order information processing modes, were more oriented towards achieving a higher-level informal reasoning quality. The regression analyses further showed that the "richness" of the students' knowledge structures explained 25 % of the variation in their rebuttal construction, an important indicator of reasoning quality, indicating the significance of the role of students' sophisticated knowledge structure in SSI reasoning. Besides, this study also provides some initial evidence for the significant role of the "core" concept within one's knowledge structure in one's SSI reasoning. The findings in this study suggest that, in SSI-based instruction, science instructors should try to identify students' core concepts within their prior knowledge regarding the SSI, and then they should try to guide students to construct and structure relevant concepts or ideas regarding the SSI based on their core concepts. Thus, students could obtain extended and well-organized knowledge structures, which would then help them achieve better learning transfer in dealing with SSIs.

    The Phylogenetic tree is a visual representation depicts a hypothesis about the evolutionary relationship among taxa. Evolutionary experts use this representation to evaluate the evidence for evolution. The phylogenetic tree is currently growing for many disciplines in biology. Consequently, learning about the phylogenetic tree has become an important part of biological education and an interesting area of biology education research. Skill to understanding and reasoning of the phylogenetic tree, (called tree thinking) is an important skill for biology students. However, research showed many students have difficulty in interpreting, constructing, and comparing among the phylogenetic tree, as well as experiencing a misconception in the understanding of the phylogenetic tree. Students are often not taught how to reason about evolutionary relationship depicted in the diagram. Students are also not provided with information about the underlying theory and process of phylogenetic. This study aims to investigate the initial ability of undergraduate students in understanding and reasoning of the phylogenetic tree. The research method is the descriptive method. Students are given multiple choice questions and an essay that representative by tree thinking elements. Each correct answer made percentages. Each student is also given questionnaires. The results showed that the undergraduate students’ initial ability in understanding and reasoning phylogenetic tree is low. Many students are not able to answer questions about the phylogenetic tree. Only 19 % undergraduate student who answered correctly on indicator evaluate the evolutionary relationship among taxa, 25% undergraduate student who answered correctly on indicator applying concepts of the clade, 17% undergraduate student who answered correctly on indicator determines the character evolution, and only a few undergraduate student who can construct the phylogenetic tree.

    2015-07-01

    Relationships between sixth grade students' moon journaling and students' spatial-scientific reasoning after implementation of an Earth/Space unit were examined. Teachers used the project-based Realistic Explorations in Astronomical Learning curriculum. We used a regression model to analyze the relationship between the students' Lunar Phases Concept Inventory (LPCI) post-test score variables and several predictors, including moon journal score, number of moon journal entries, student gender, teacher experience, and pre-test score. The model shows that students who performed better on moon journals, both in terms of overall score and number of entries, tended to score higher on the LPCI. For every 1 point increase in the overall moon journal score, participants scored 0.18 points (out of 20) or nearly 1% point higher on the LPCI post-test when holding constant the effects of the other two predictors. Similarly, students who increased their scores by 1 point in the overall moon journal score scored approximately 1% higher in the Periodic Patterns (PP) and Geometric Spatial Visualization (GSV) domains of the LPCI. Also, student gender and teacher experience were shown to be significant predictors of post-GSV scores on the LPCI in addition to the pre-test scores, overall moon journal score, and number of entries that were also significant predictors on the LPCI overall score and the PP domain. This study is unique in the purposeful link created between student moon observations and spatial skills. The use of moon journals distinguishes this study further by fostering scientific observation along with skills from across science, technology, engineering, and mathematics disciplines.

    2014-01-01

    Recent calls for improving undergraduate biology education have emphasized the importance of students learning to apply quantitative skills to biological problems. Motivated by students' apparent inability to transfer their existing quantitative skills to biological contexts, we designed and taught an introductory molecular and cell biology course in which we integrated application of prerequisite mathematical skills with biology content and reasoning throughout all aspects of the course. In this paper, we describe the principles of our course design and present illustrative examples of course materials integrating mathematics and biology. We also designed an outcome assessment made up of items testing students' understanding of biology concepts and their ability to apply mathematical skills in biological contexts and administered it as a pre/postcourse test to students in the experimental section and other sections of the same course. Precourse results confirmed students' inability to spontaneously transfer their prerequisite mathematics skills to biological problems. Pre/postcourse outcome assessment comparisons showed that, compared with students in other sections, students in the experimental section made greater gains on integrated math/biology items. They also made comparable gains on biology items, indicating that integrating quantitative skills into an introductory biology course does not have a deleterious effect on students' biology learning.

    To improve the clinical reasoning skills of postgraduate students in internal medicine through 2 kinds of extracurricular books: medical nonfiction and nonmedical fiction. Clinical reasoning is difficult to define, understand, observe, teach, and measure. This is an educational innovation under an experimental framework based on a cognitive intervention grounded in constructivist and cognitivist theories. This study was conducted from June 1, 2014, through May 31, 2015. It was a pre-post, randomized, controlled, prospective, mixed-methods, small-group study. The intervention was through medical nonfiction and nonmedical fiction books. The process was structured to ensure that the students would read the material in phases and reflect on them. Clinical reasoning (pretests and posttests) was quantitatively assessed using the Diagnostic Thinking Inventory (DTI) and clinical reasoning exercises (CREs) and their assessment using a rubric. A qualitative design was used, and face-to-face semistructured interviews were conducted. Posttest total scores (DTI=188.92; CREs=53.92) were higher for the study group after the intervention compared with its own pretest scores (DTI=165.25; CREs=41.17) and with the pretest (DTI=159.27; CRE=40.73) and posttest (DTI=166.91; CREs=41.18) scores of the control group. Interviews with the study group confirmed that the intervention was acceptable and useful in daily practice. We introduced, evaluated, and proved an approach to teaching-learning clinical reasoning based on the assumption that the clinical reasoning skills of postgraduate students in internal medicine can be enhanced through 2 kinds of extracurricular books and that fun as well as interest will enhance learning. This study is not only about teaching-learning clinical reasoning but also about the humanities in medical education. Copyright © 2016 Mayo Foundation for Medical Education and Research.

    Southard, Katelyn; Wince, Tyler; Meddleton, Shanice; Bolger, Molly S

    2016-01-01

    Research has suggested that teaching and learning in molecular and cellular biology (MCB) is difficult. We used a new lens to understand undergraduate reasoning about molecular mechanisms: the knowledge-integration approach to conceptual change. Knowledge integration is the dynamic process by which learners acquire new ideas, develop connections between ideas, and reorganize and restructure prior knowledge. Semistructured, clinical think-aloud interviews were conducted with introductory and upper-division MCB students. Interviews included a written conceptual assessment, a concept-mapping activity, and an opportunity to explain the biomechanisms of DNA replication, transcription, and translation. Student reasoning patterns were explored through mixed-method analyses. Results suggested that students must sort mechanistic entities into appropriate mental categories that reflect the nature of MCB mechanisms and that conflation between these categories is common. We also showed how connections between molecular mechanisms and their biological roles are part of building an integrated knowledge network as students develop expertise. We observed differences in the nature of connections between ideas related to different forms of reasoning. Finally, we provide a tentative model for MCB knowledge integration and suggest its implications for undergraduate learning. © 2016 K. Southard et al.

    Kuiper, R; Pesut, D; Kautz, D

    2009-10-02

    The purpose of this paper is to describe the research surrounding the theories and models the authors united to describe the essential components of clinical reasoning in nursing practice education. The research was conducted with nursing students in health care settings through the application of teaching and learning strategies with the Self-Regulated Learning Model (SRL) and the Outcome-Present-State-Test (OPT) Model of Reflective Clinical Reasoning. Standardized nursing languages provided the content and clinical vocabulary for the clinical reasoning task. This descriptive study described the application of the OPT model of clinical reasoning, use of nursing language content, and reflective journals based on the SRL model with 66 undergraduate nursing students over an 8 month period of time. The study tested the idea that self-regulation of clinical reasoning skills can be developed using self-regulation theory and the OPT model. This research supports a framework for effective teaching and learning methods to promote and document learner progress in mastering clinical reasoning skills. Self-regulated Learning strategies coupled with the OPT model suggest benefits of self-observation and self-monitoring during clinical reasoning activities, and pinpoints where guidance is needed for the development of cognitive and metacognitive awareness. Thinking and reasoning about the complexities of patient care needs requires attention to the content, processes and outcomes that make a nursing care difference. These principles and concepts are valuable to clinical decision making for nurses globally as they deal with local, regional, national and international health care issues.

    2012-01-01

    In this study, we used targeted active-learning activities to help students improve their ways of reasoning about carbon flow in ecosystems. The results of a validated ecology conceptual inventory (diagnostic question clusters [DQCs]) provided us with information about students' understanding of and reasoning about transformation of inorganic and organic carbon-containing compounds in biological systems. These results helped us identify specific active-learning exercises that would be responsive to students' existing knowledge. The effects of the active-learning interventions were then examined through analysis of students' pre- and postinstruction responses on the DQCs. The biology and non–biology majors participating in this study attended a range of institutions and the instructors varied in their use of active learning; one lecture-only comparison class was included. Changes in pre- to postinstruction scores on the DQCs showed that an instructor's teaching method had a highly significant effect on student reasoning following course instruction, especially for questions pertaining to cellular-level, carbon-transforming processes. We conclude that using targeted in-class activities had a beneficial effect on student learning regardless of major or class size, and argue that using diagnostic questions to identify effective learning activities is a valuable strategy for promoting learning, as gains from lecture-only classes were minimal.

    2018-05-01

    The purpose of this investigation was to qualitatively describe high school students' reasons for their science dispositions (attitude, perception, and self-confidence) based on their long-term experience with innovative technology-embedded environmental research projects. Students in small groups conducted research projects in and out of school with the help of their teachers and community experts (scientists and engineers). During the 3-year period of this nationally funded project, a total of 135 students from five schools in a mid-west State participated in research activities. Of the 135 students, 53 students were individually interviewed to explore reasons for their science dispositions. Students' reasons for each disposition were grouped into categories, and corresponding frequency was converted to a percentage. The categories of reasons were not only attributed to the use of innovative technologies in environmental research but also the contexts and events that surrounded it. The reasons that influenced students' science dispositions positively were because engaging in environmental research projects with technology contributed to easing fear and difficulty, building a research team, disseminating findings, communicating with the community, researching with scientists, training by teachers, and acknowledging teachers' knowledge. These results advanced how and why students develop science dispositions in the positive direction, which are as follows: building science teacher capacity, developing a community of inquirers, and committing to improve pedagogical practices.

Through mathematical analogy students are required to be able to look for similarities or relationship nature of the two concepts are the same or different by comparison, then draw a conclusion from the similitude. Thus the analogy can be used as an explanation or as the basis of reasoning. Before starting the analogy of learning mathematics, teachers should examine the ability of understanding mathematical concepts of students, because of the level of understanding of students will affect the power of reason. Tasks (problems mathematical analogy included non-routine matter, therefore the required readiness of teachers to make it. In each question contained mathematical analogy same or different concepts, so it takes quite a lot of material. Steps to make about the mathematical analogy, are: a assemble all the concepts in mathematics student has learned; b Similarly stacking properties / relationships contained in any concept, and c select materials that have a nature / relationship analogous.

  7. Middle School Students' Use of Epistemological Resources while Reasoning about Science Performance Tasks and Media Reports of Socioscientific Issues

    Science.gov (United States)

    Buckingham, Brandy L. E.

    The goal of science education is to prepare students to make decisions about the complicated socioscientific issues that are an inescapable part of modern life, from personal medical decisions to evaluating a political candidate's environmental platform. We cannot expect adults to maintain a deep conceptual understanding of the current state of every branch of science that might prove relevant to their lives, so we must prepare them to rely on other knowledge to make these decisions. Epistemological beliefs about scientific knowledge--what it is, its purpose, how it is constructed--are one type of knowledge that could be brought to bear when evaluating scientific claims. Complicating this situation is the fact that most adults will get most of their information about these socioscientific issues from the news media. Journalists do not have the same goals or norms as scientists, and this media lens can distort scientific issues. This dissertation addresses the question of whether we can assess epistemological change in a way that gives us meaningful information about how people will apply their epistemological understanding of science when they make decisions in the real world. First, I designed a written assessment made up of performance tasks to assess middle school students' implicit epistemological beliefs, and looked at whether we can use such an assessment to see epistemological change over two years. I then gave the same students news articles about whether there is a link between vaccines and autism and looked at their reasoning about this issue and how the journalistic features of two different articles impacted their reasoning. Finally, I examined the external validity of the epistemology assessment by looking at whether it predicted anything about students' responses to the news articles. While I was able to find evidence of differences between eighth graders' and sixth graders' use of epistemological resources within the performance tasks, I found that

    Simonneaux, Laurence; Simonneaux, Jean

    2009-09-01

    In this article, we study third-year university students' reasoning about three controversial socio-scientific issues from the viewpoint of education for sustainable development: local issues (the reintroduction of bears in the Pyrenees in France, wolves in the Mercantour) and a global one (global warming). We used the theoretical frameworks of social representations and of socio-scientific reasoning. Students' reasoning varies according to the issues, in particular because of their emotional proximity with the issues and their socio-cultural origin. About this kind of issues, it seems pertinent to integrate into the operations of socio-scientific reasoning not only the consideration of values, but also the analysis of the modes of governance and the place given to politics.

    1989-12-01

    A study assessed the effect of incorporating medical ethics into the medical curriculum and the relative effects of two methods of implementing that curriculum, namely, lecture and case-study discussions. Results indicate a statistically significant increase (p less than or equal to .0001) in the level of moral reasoning of students exposed to the medical ethics course, regardless of format. Moreover, the unadjusted posttest scores indicated that the case-study method was significantly (p less than or equal to .03) more effective than the lecture method in increasing students' level of moral reasoning. When adjustment were made for the pretest scores, however, this difference was not statistically significant (p less than or equal to .18). Regression analysis by linear panel techniques revealed that age, gender, undergraduate grade-point average, and scores on the Medical College Admission Test were not related to the changes in moral-reasoning scores. All of the variance that could be explained was due to the students' being in one of the two experimental groups. In comparison with the control group, the change associated with each experimental format was statistically significant (lecture, p less than or equal to .004; case study, p less than or equal to .0001). Various explanations for these findings and their implications are given.

    This study aimed to explore reasons for poor performance in prescription writing stations of the objective structured practical examination (OSPE) and absenteeism in prescription writing sessions among preclerkship medical students at the Arabian Gulf University (AGU) in Manama, Bahrain. This descriptive study was carried out between September 2014 and June 2015 among 157 preclerkship medical students at AGU. Data were collected using focus group discussions and a questionnaire with closed- and open-ended items. All 157 students participated in the study (response rate: 100.0%). The most frequently cited reasons for poor performance in OSPE stations were an inability to select the correct drugs (79.6%), treatment duration (69.4%), drug quantity (69.4%) and drug formulation (68.2%). Additionally, students reported inadequate time for completing the stations (68.8%). During focus group discussions, students reported other reasons for poor performance, including examination stress and the difficulty of the stations. Absenteeism was attributed to the length of each session (55.4%), lack of interest (50.3%), reliance on peers for information (48.4%) and optional attendance policies (47.1%). Repetitive material, large group sessions, unmet student expectations and the proximity of the sessions to summative examinations were also indicated to contribute to absenteeism according to open-ended responses or focus group discussions. This study suggests that AGU medical students perform poorly in prescription writing OSPE stations because of inadequate clinical pharmacology knowledge. Participation in prescription writing sessions needs to be enhanced by addressing the concerns identified in this study. Strategies to improve attendance and performance should take into account the learner-teacher relationship.

    Dental students should develop an understanding of the barriers to and frustrations with accessing dental care and maintaining optimal oral health experienced by persons with limited resources rather than blaming the patient or caregiver. Developing this understanding may be aided by helping students learn about the lives of underserved and vulnerable patients they will encounter not only in extramural rotations, but throughout their careers. The aim of this study was to determine if dental students' understanding of daily challenges faced by families with low income changed as a result of a poverty simulation. In 2015 and 2016, an experiential poverty simulation was used to prepare third-year dental students at one U.S. dental school for their upcoming required community-based rotations. In 2015, United Way staff conducted the simulation using the Missouri Community Action Poverty Simulation (CAPS); in 2016, faculty members trained in CAPS conducted the simulation using a modified version of the tool. In the simulation, students were assigned to family units experiencing various types of hardship and were given specific identities for role-playing. A retrospective pretest and a posttest were used to assess change in levels of student understanding after the simulation. Students assessed their level of understanding in five domains: financial pressures, difficult choices, difficulties in improving one's situation, emotional stressors, and impact of community resources for those living in poverty. The survey response rates in 2015 and 2016 were 86% and 74%, respectively. For each of the five domains, students' understanding increased from 58% to 74% per domain. The majority reported that the exercise was very valuable or somewhat valuable (74% in 2015, 88% in 2016). This study found that a poverty simulation was effective in raising dental students' understanding of the challenges faced by low-income families. It also discovered that framing the issues in the

    Science Camp for Chemistry Concepts was the project which designed to provide local students with opportunities to apply chemistry concepts and thereby developing their 21st century skills. The three study purposes were 1) to construct and develop chemistry stations for encouraging students' understandings in chemistry concepts based on constructivist-informed laboratory, 2) to compare students' understandings in chemistry concepts before and after using chemistry learning stations, and 3) to study students' satisfactions of using their 21st century skills in science camp activities. The research samples were 67 students who attended the 1-day science camp. They were levels 10 to 11 students in SumsaoPittayakarn School, UdonThani Province, Thailand. Four constructivist-informed laboratory stations of chemistry concepts were designed for each group. Each station consisted of a chemistry scenario, a question, answers in tier 1 and supporting reasons in tier 2, and 4 sets of experimental instruments. Four to five-member subgroups of four student groups parallel participated in laboratory station for an hour in each station. Student activities in each station concluded of individual pretest, group prediction, experimental design, testing out and collection data, interpreting the results, group conclusion, and individual post-test. Data collection was done by station mentors using two-tier multiple choice questions, students' written work and interviews. Data triangulation was used for interpreting and confirming students' understandings of chemistry concepts which divided into five levels, Sound Understanding (SU), Partial Understanding (PU), Specific Misconception (SM), No Understanding (NU) and No Response (NR), before and after collaborating at each station. The study results found the following: 1) four constructivist-laboratory stations were successfully designed and used to investigate student' understandings in chemistry concepts via collaborative workshop of

    The overall aim of the study was to explore health care students´ understanding of core concepts in pharmacology. An interview study was conducted among twelve students in their final semester of the medical program (n = 4), the nursing program (n = 4), and the specialist nursing program in primary health care (n = 4) from two Swedish universities. The participants were individually presented with two pharmacological clinically relevant written patient cases, which they were to analyze and propose a solution to. Participants were allowed to use the Swedish national drug formulary. Immediately thereafter the students were interviewed about their assessments. The interviews were audio-recorded and transcribed verbatim. A thematic analysis was used to identify units of meaning in each interview. The units were organized into three clusters: pharmacodynamics, pharmacokinetics, and drug interactions. Subsequent procedure consisted of scoring the quality of students´ understanding of core concepts. Non-parametric statistics were employed. The study participants were in general able to define pharmacological concepts, but showed less ability to discuss the meaning of the concepts in depth and to implement these in a clinical context. The participants found it easier to grasp concepts related to pharmacodynamics than pharmacokinetics and drug interactions. These results indicate that education aiming to prepare future health care professionals for understanding of more complex pharmacological reasoning and decision-making needs to be more focused and effective.

  20. Science Teachers' Analogical Reasoning

    Mozzer, Nilmara Braga; Justi, Rosária

    2013-08-01

    Analogies can play a relevant role in students' learning. However, for the effective use of analogies, teachers should not only have a well-prepared repertoire of validated analogies, which could serve as bridges between the students' prior knowledge and the scientific knowledge they desire them to understand, but also know how to introduce analogies in their lessons. Both aspects have been discussed in the literature in the last few decades. However, almost nothing is known about how teachers draw their own analogies for instructional purposes or, in other words, about how they reason analogically when planning and conducting teaching. This is the focus of this paper. Six secondary teachers were individually interviewed; the aim was to characterize how they perform each of the analogical reasoning subprocesses, as well as to identify their views on analogies and their use in science teaching. The results were analyzed by considering elements of both theories about analogical reasoning: the structural mapping proposed by Gentner and the analogical mechanism described by Vosniadou. A comprehensive discussion of our results makes it evident that teachers' content knowledge on scientific topics and on analogies as well as their pedagogical content knowledge on the use of analogies influence all their analogical reasoning subprocesses. Our results also point to the need for improving teachers' knowledge about analogies and their ability to perform analogical reasoning.

    This article describes the case study on postgraduate students by using descriptive method. A problem is designed to facilitate the reasoning in the topic of Chi-Square test. The problem was given to two male students with different ages to investigate the gesture pattern and it will be related to their reasoning process. The indicators in reasoning problem can obtain the conclusion of analogy and generalization, and arrange the conjectures. This study refers to some questions—whether unique gesture is for every individual or to identify the pattern of the gesture used by the students with different ages. Reasoning problem was employed to collect the data. Two students were asked to collaborate to reason the problem. The discussion process recorded in using video tape to observe the gestures. The video recorded are explained clearly in this writing. Prosodic cues such as time, conversation text, gesture that appears, might help in understanding the gesture. The purpose of this study is to investigate whether different ages influences the maturity in collaboration observed from gesture perspective. The finding of this study shows that age is not a primary factor that influences the gesture in that reasoning process. In this case, adult gesture or gesture performed by order student does not show that he achieves, maintains, and focuses on the problem earlier on. Adult gesture also does not strengthen and expand the meaning if the student’s words or the language used in reasoning is not familiar for younger student. Adult gesture also does not affect cognitive uncertainty in mathematics reasoning. The future research is suggested to take more samples to find the consistency from that statement.

    Skills in working on the geometry problems great needs of the competence of Geometric Reasoning. As a teacher candidate, State Islamic University (UIN) students need to have the competence of this Geometric Reasoning. When the geometric reasoning in solving of geometry problems has grown well, it is expected the students are able to write their ideas to be communicative for the reader. The ability of a student's mathematical communication is supposed to be used as a marker of the growth of their Geometric Reasoning. Thus, the search for the growth of geometric reasoning in solving of analytic geometry problems will be characterized by the growth of mathematical communication abilities whose work is complete, correct and sequential, especially in writing. Preceded with qualitative research, this article was the result of a study that explores the problem: Was the search for the growth of geometric reasoning in solving analytic geometry problems could be characterized by the growth of mathematical communication abilities? The main activities in this research were done through a series of activities: (1) Lecturer trains the students to work on analytic geometry problems that were not routine and algorithmic process but many problems that the process requires high reasoning and divergent/open ended. (2) Students were asked to do the problems independently, in detail, complete, order, and correct. (3) Student answers were then corrected each its stage. (4) Then taken 6 students as the subject of this research. (5) Research subjects were interviewed and researchers conducted triangulation. The results of this research, (1) Mathematics Education student of UIN Semarang, had adequate the mathematical communication ability, (2) the ability of this mathematical communication, could be a marker of the geometric reasoning in solving of problems, and (3) the geometric reasoning of UIN students had grown in a category that tends to be good.

    Health professionals need to develop analytic and diagnostic thinking skills and not just a mere accumulation of large amount of facts. Hence, Case Based Learning (CBL) has been used in the medical curriculum for this reason, so that the students are exposed to the real medical problems, which helps them in develop analysing abilities. This also helps them in interpreting and solving the problems and in the course of doing this, they develop interest. In addition to didactic lectures, CBL was used as a learning method. This study was conducted in the Department of Biochemistry, S.B.K.S.M.I and R.C, Sumandeep Vidyapeeth ,Piparia, Gujarat, India. A group of 100 students were selected and they were divided into two groups as the control group and the study group. A total of 50 students were introduced to case based learning, which formed the study group and 50 students who attended didactic lectures formed the control group.

    The reasoning is one of the mathematical abilities that have very complex implications. This complexity causes reasoning including abilities that are not easily attainable by students. Similarly, studies dealing with reason are quite diverse, primarily concerned with the quality of mathematical reasoning. The objective of this study was to determine the quality of mathematical reasoning based perspective Lithner. Lithner looked at how the environment affects the mathematical reasoning. In this regard, Lithner made two perspectives, namely imitative reasoning and creative reasoning. Imitative reasoning can be memorized and algorithmic reasoning. The Result study shows that although the students generally still have problems in reasoning. Students tend to be on imitative reasoning which means that students tend to use a routine procedure when dealing with reasoning. It is also shown that the traditional approach still dominates on the situation of students’ daily learning.

    Science.gov (United States)

    May, Stephen A

    2013-01-01

    Confusion about the nature of human reasoning and its appropriate application to patients has hampered veterinary students' development of these skills. Expertise is associated with greater ability to deploy pattern recognition (type 1 reasoning), which is aided by progressive development of data-driven, forward reasoning (in contrast to scientific, backward reasoning), analytical approaches that lead to schema acquisition. The associative nature of type 1 reasoning makes it prone to bias, particularly in the face of "cognitive miserliness," when clues that indicate the need for triangulation with an analytical approach are ignored. However, combined reasoning approaches, from the earliest stages, are more successful than one approach alone, so it is important that those involved in curricular design and delivery promote student understanding of reasoning generally, and the situations in which reasoning goes awry, and develop students' ability to reason safely and accurately whether presented with a familiar case or with a case that they have never seen before.

    The application of a systems approach to assessing biological systems provides hope for a coherent understanding of cell dynamics patterns and their relationship to plant life. This action required the reasoning about complex systems. In other sides, there were a lot of researchers who provided the proof about the instructional successions. They involved the multiple external representations which improved the biological learning. The researcher conducted an investigation using one shoot case study design which involved 30 students in proving that the MERs worksheets could affect the student's achievement of reasoning about complex system. The data had been collected based on test of reasoning about complex system and student's identification result who worked through MERs. The result showed that only partially students could achieve reasoning about system complex, but their MERs skill could support their reasoning ability of complex system. This study could bring a new hope to develop the MERs worksheet as a tool to facilitate the reasoning about complex system.

    Representational and mathematical reasoning ability are very important ability as basic in mathematics learning process. The 2013 curriculum suggests that the use of a scientific approach emphasizes higher order thinking skills. Therefore, a scientific approach is required in mathematics learning to improve ability of representation and mathematical reasoning. The objectives of this research are: (1) to analyze representational and reasoning abilities, (2) to analyze indicators affecting the ability of representation and mathematical reasoning, (3) to analyze scientific approaches that can improve the ability of representation and mathematical reasoning. The subject of this research is the students of mathematics prospective teachers in the first semester at Private Higher Education of Bandung City. The research method of this research was descriptive analysis. The research data were collected using reasoning and representation tests on sixty-one students. Data processing was done by descriptive analysis specified based on the indicators of representation ability and mathematical reasoning that influenced it. The results of this first-year study showed that students still had many weaknesses in reasoning and mathematical representation that were influenced by the ability to understand the indicators of both capabilities. After observing the results of the first-year research, then in the second and third year, the development of teaching materials with a scientific approach in accordance with the needs of prospective students was planned.

    Troubleshooting systems is an integral part of experimental physics in both research and educational settings. Accordingly, ability to troubleshoot is an important learning goal for undergraduate physics lab courses. We investigate students' model-based reasoning on a troubleshooting task using data collected in think-aloud interviews during which pairs of students from two institutions attempted to diagnose and repair a malfunctioning circuit. Our analysis scheme was informed by the Experimental Modeling Framework, which describes physicists' use of mathematical and conceptual models when reasoning about experimental systems. We show that system and subsystem models were crucial for the evaluation of repairs to the circuit and played an important role in some troubleshooting strategies.

    Troubleshooting systems is an integral part of experimental physics in both research and educational settings. Accordingly, ability to troubleshoot is an important learning goal for undergraduate physics lab courses. We investigate students' model-based reasoning on a troubleshooting task using data collected in think-aloud interviews during which pairs of students from two institutions attempted to diagnose and repair a malfunctioning circuit. Our analysis scheme was informed by the Experimental Modeling Framework, which describes physicists' use of mathematical and conceptual models when reasoning about experimental systems.

    Academic dishonesty, including cheating and plagiarism, is on the rise in colleges, particularly among engineering students. While students decide to engage in these behaviors for many different reasons, academic integrity training can help improve their understanding of ethical decision making. The two studies outlined in this paper assess the effectiveness of an online module in increasing academic integrity among first semester engineering students. Study 1 tested the effectiveness of an academic honesty tutorial by using a between groups design with a Time 1- and Time 2-test. An academic honesty quiz assessed participants' knowledge at both time points. Study 2, which incorporated an improved version of the module and quiz, utilized a between groups design with three assessment time points. The additional Time 3-test allowed researchers to test for retention of information. Results were analyzed using ANCOVA and t tests. In Study 1, the experimental group exhibited significant improvement on the plagiarism items, but not the total score. However, at Time 2 there was no significant difference between groups after controlling for Time 1 scores. In Study 2, between- and within-group analyses suggest there was a significant improvement in total scores, but not plagiarism scores, after exposure to the tutorial. Overall, the academic integrity module impacted participants as evidenced by changes in total score and on specific plagiarism items. Although future implementation of the tutorial and quiz would benefit from modifications to reduce ceiling effects and improve assessment of knowledge, the results suggest such tutorial may be one valuable element in a systems approach to improving the academic integrity of engineering students.

  15. A case study of the abductive reasoning processes of pre-service elementary education students in a role playing setting concerning a mock senate hearing on global climate change

    Science.gov (United States)

    Petty, Michael Eugene

    Science education has a rich history of studies into the impact of analogical reasoning upon researcher and student alike. These have focused on how induction and deduction are utilized in determining the appropriateness of the analogy being scrutinized. Research in artificial intelligence has demonstrated that human cognition cannot be modeled with only inductive and deductive forms of logic. Charles S. Peirce proposed abduction as a form of logic central to the process of inquiry and discovery. This involves reasoning from observation to best explanation or hypothesis. Peirce's Theory of Signs provided the theoretical foundation and a model of abduction developed by Shank and Cunningham from Peirce's theory offered the conceptual basis for the study. This study uses discourse analysis to attempt to understand the abductive reasoning processes of two groups of students as they interpret new information concerning the political and scientific perspective of the Greening Earth Society and the Center for Disease Control in an authentic, undergraduate-level classroom setting. The five students were members of a capstone course in science education for pre-service elementary education majors who had an interest in science education. The entire class was comprised of fourteen students partitioned into five groups for the culminating exercise for the course. Analysis was carried out using journal entries, audiotapes of planning sessions, a brief summary of their understanding, and videotapes of the mock Senate hearings. The results demonstrated that different members of the group arrived at their understanding using different pathways suggested by the model. While some proceeded linearly, others skipped some stages and later came back to find supportive evidence to strengthen their beliefs. The model is useful in understanding their abductive processes and may provide insight into how we might consider the process in the design of future curriculum for elementary science

    Full Text Available Introduction: The aim of the present study was assessed the effect of educational program for preventing of ecstasy abuse among college students in Hamadan based on Theory of Reason Action (TRA. Method: A quasi-experimental study carried out in college students. A total number of 140 students were selected through randomized cluster sampling and randomly assigned to the intervention (n=70 and the control (n=70 groups. Data-gathering tools consisted of a two-part questionnaire: Knowledge of ecstasy abuse consequences and one scale for measuring TRA variables. Respondents in the control and experimental groups completed questionnaires at before and two months after intervention. Results: The results showed that among constructs of the theory of reason action, subjective norms were better predictor of ecstasy abuse. There were significant differences between the scores of reason action constructs namely: attitude against drug abuse, subjective norms and intention of ecstasy abuse with consideration of group (witness and experimental. Conclusion: With regard to the results of the current study, special education based on Theory of Reasoned Action is effective in improving of attitude, subjective norm and behavioral intention of students. Therefore it is highly recommended that TRA education can be use for preventing of drug abuse education programs.

  20. Diagnosing Students' Understanding of the Nature of Models

    Gogolin, Sarah; Krüger, Dirk

    2017-10-01

    Students' understanding of models in science has been subject to a number of investigations. The instruments the researchers used are suitable for educational research but, due to their complexity, cannot be employed directly by teachers. This article presents forced choice (FC) tasks, which, assembled as a diagnostic instrument, are supposed to measure students' understanding of the nature of models efficiently, while being sensitive enough to detect differences between individuals. In order to evaluate if the diagnostic instrument is suitable for its intended use, we propose an approach that complies with the demand to integrate students' responses to the tasks into the validation process. Evidence for validity was gathered based on relations to other variables and on students' response processes. Students' understanding of the nature of models was assessed using three methods: FC tasks, open-ended tasks and interviews ( N = 448). Furthermore, concurrent think-aloud protocols ( N = 30) were performed. The results suggest that the method and the age of the students have an effect on their understanding of the nature of models. A good understanding of the FC tasks as well as a convergence in the findings across the three methods was documented for grades eleven and twelve. This indicates that teachers can use the diagnostic instrument for an efficient and, at the same time, valid diagnosis for this group. Finally, the findings of this article may provide a possible explanation for alternative findings from previous studies as a result of specific methods that were used.

  2. Assessing and Improving Student Understanding of Tree-Thinking

    Science.gov (United States)

    Kummer, Tyler A.

    Evolution is the unifying theory of biology. The importance of understanding evolution by those who study the origins, diversification and diversity life cannot be overstated. Because of its importance, in addition to a scientific study of evolution, many researchers have spent time studying the acceptance and the teaching of evolution. Phylogenetic Systematics is the field of study developed to understand the evolutionary history of organisms, traits, and genes. Tree-thinking is the term by which we identify concepts related to the evolutionary history of organisms. It is vital that those who undertake a study of biology be able to understand and interpret what information these phylogenies are meant to convey. In this project, we evaluated the current impact a traditional study of biology has on the misconceptions students hold by assessing tree-thinking in freshman biology students to those nearing the end of their studies. We found that the impact of studying biology was varied with some misconceptions changing significantly while others persisted. Despite the importance of tree-thinking no appropriately developed concept inventory exists to measure student understanding of these important concepts. We developed a concept inventory capable of filling this important need and provide evidence to support its use among undergraduate students. Finally, we developed and modified activities as well as courses based on best practices to improve teaching and learning of tree-thinking and organismal diversity. We accomplished this by focusing on two key questions. First, how do we best introduce students to tree-thinking and second does tree-thinking as a course theme enhance student understanding of not only tree-thinking but also organismal diversity. We found important evidence suggesting that introducing students to tree-thinking via building evolutionary trees was less successful than introducing the concept via tree interpretation and may have in fact introduced or

    During their clerkships, medical students are meant to expand their clinical reasoning skills during their patient encounters. Observation of these encounters could reveal important information on the students' clinical reasoning abilities, especially during history taking. A grounded theory approach was used to analyze what expert physicians apply as indicators in their assessment of medical students' diagnostic reasoning abilities during history taking. Twelve randomly selected clinical encounter recordings of students at the end of the internal medicine clerkships were observed by six expert assessors, who were prompted to formulate their assessment criteria in a think-aloud procedure. These formulations were then analyzed to identify the common denominators and leading principles. The main indicators of clinical reasoning ability were abstracted from students' observable acts during history taking in the encounter. These were: taking control, recognizing and responding to relevant information, specifying symptoms, asking specific questions that point to pathophysiological thinking, placing questions in a logical order, checking agreement with patients, summarizing and body language. In addition, patients' acts and the course, result and efficiency of the conversation were identified as indicators of clinical reasoning, whereas context, using self as a reference, and emotion/feelings were identified by the clinicians as variables in their assessment of clinical reasoning. In observing and assessing clinical reasoning during history taking by medical students, general and specific phenomena to be used as indicators for this process could be identified. These phenomena can be traced back to theories on the development and the process of clinical reasoning.

  6. Informal reasoning regarding socioscientific issues: The influence of morality and content knowledge

    Science.gov (United States)

    Sadler, Troy Dow

    This study focused on informal reasoning regarding socioscientific issues. It explored how morality and content knowledge influenced the negotiation and resolution of contentious and complex scenarios based on genetic engineering. Two hundred and sixty-nine undergraduate students completed a quantitative test of genetics concepts. A sub-set of the students (n = 30) who completed this instrument and represented divergent levels of content knowledge participated in two individual interviews, during which they discussed their ideas, reactions, and solutions to three gene therapy scenarios and three cloning scenarios. A mixed-methods approach was used to examine patterns of informal reasoning and the influence of morality, the effects of content knowledge on the use of informal reasoning patterns, and the effects of content knowledge on the quality of informal reasoning. Students demonstrated evidence of rationalistic, emotive, and intuitive forms of informal reasoning. Rationalistic informal reasoning described reason-based considerations; emotive informal reasoning described care-based considerations; and intuitive reasoning described considerations based on immediate reactions to the context of a scenario. Participants frequently relied on combinations of these reasoning patterns as they worked to resolve individual socioscientific scenarios. Most of the participants appreciated at least some of the moral implications of their decisions, and these considerations were typically interwoven within an overall pattern of informal reasoning. Although differences in content knowledge were not found to be related to modes of informal reasoning (rationalistic, emotive, and informal), data did indicate that differences in content knowledge were related to variations in informal reasoning quality. Participants, with more advanced understandings of genetics, demonstrated fewer instances of reasoning flaws, as defined by a priori criteria (intra-scenario coherence, inter

  7. Using Computer Simulations for Promoting Model-based Reasoning. Epistemological and Educational Dimensions

    2017-11-01

    Scientific reasoning is particularly pertinent to science education since it is closely related to the content and methodologies of science and contributes to scientific literacy. Much of the research in science education investigates the appropriate framework and teaching methods and tools needed to promote students' ability to reason and evaluate in a scientific way. This paper aims (a) to contribute to an extended understanding of the nature and pedagogical importance of model-based reasoning and (b) to exemplify how using computer simulations can support students' model-based reasoning. We provide first a background for both scientific reasoning and computer simulations, based on the relevant philosophical views and the related educational discussion. This background suggests that the model-based framework provides an epistemologically valid and pedagogically appropriate basis for teaching scientific reasoning and for helping students develop sounder reasoning and decision-taking abilities and explains how using computer simulations can foster these abilities. We then provide some examples illustrating the use of computer simulations to support model-based reasoning and evaluation activities in the classroom. The examples reflect the procedure and criteria for evaluating models in science and demonstrate the educational advantages of their application in classroom reasoning activities.

    Somroob, S.; Wattanakasiwich, P.

    2017-09-01

    This study aimed to investigate students’ understanding and develop instructional material on a topic of simple harmonic motion. Participants were 60 students taking a course on vibrations and wave and 46 students taking a course on Physics 2 and 28 students taking a course on Fundamental Physics 2 on the 2nd semester of an academic year 2016. A 16-question conceptual test and tutorial activities had been developed from previous research findings and evaluated by three physics experts in teaching mechanics before using in a real classroom. Data collection included both qualitative and quantitative methods. Item analysis and whole-test analysis were determined from student responses in the conceptual test. As results, most students had misconceptions about restoring force and they had problems connecting mathematical solutions to real motions, especially phase angle. Moreover, they had problems with interpreting mechanical energy from graphs and diagrams of the motion. These results were used to develop effective instructional materials to enhance student abilities in understanding simple harmonic motion in term of multiple representations.

  12. Hermeneutics of reason: the principle of common rationality as premise of understanding the Other(s

    Directory of Open Access Journals (Sweden)

    Mihai Stelian Rusu

    2013-06-01

    Full Text Available The central argument defended in this paper is made up of two interconnected statements: i that a minimally defined rationality is an anthropological constant, being shared by all conceivable human cultures; and ii that this “commonality of reason” constitutes the basis on which inter-cultural understanding is possible. In proving the first thesis (the universality of reason, the paper contrasts Western thought, epitomized in scientific reason, with non-Western thinking patterns, expressed by ethno-sciences, magic rituals, and other knowledge practices. The conclusion drawn from this comparison is that both modern scientific reason and non-literate peoples thought patterns are two “cognitive modes” sharing a strong structural similarity. Building on some loci classici of anthropological literature written by Malinowski, Evans-Pritchard, and Lévi-Strauss (among others, the paper argues that although modern Western science and indigenous knowledge(s share a common rational denominator, the two cognitive modes are nonetheless hierarchical, the former being epistemically superior to the latter thanks to its unique self-correcting methodology. The paper ends by arguing the case for the possibility of understanding the Other(s by way of reason, a possibility grounded on the commonality of reason between cultures.

  14. Can lessons designed with Gestalt laws of visual perception improve students' understanding of the phases of the moon?

    Science.gov (United States)

    Wistisen, Michele

    There has been limited success teaching elementary students about the phases of the moon using diagrams, personal observations, and manipulatives. One possible reason for this is that instruction has failed to apply Gestalt principles of perceptual organization to the lesson materials. To see if fourth grade students' understanding could be improved, four lessons were designed and taught using the Gestalt laws of Figure-Ground, Symmetry, and Similarity. Students (n = 54) who were taught lessons applying the Gestalt principles scored 12% higher on an assessment than students (n = 51) who only were taught lessons using the traditional methods. Though scores showed significant improvement, it is recommended to follow the American Association for the Advancement of Science guidelines and wait until 9th grade to instruct students about the phases.

    The authors examined the prevalence of and reasons, or excuses, for academic procrastination as a function of gender and academic grade level. In Study 1, a factor analysis of responses by 203 Turkish undergraduate students to an academic procrastination measure provided evidence of reliability and validity for the revised scale. In Study 2,784 students (363 women, 421 men; M age = 20.6 years, SD age = 1.74 years) completed the validated Turkish Procrastination Assessment Scale-Students. The results were that 52% of students self-reported frequent academic procrastination, with male students reporting more frequent procrastination on academic tasks than female students. Significantly more female students than male students reported greater academic procrastination because of fear of failure and laziness; male students reported more academic procrastination as a result of risk taking and rebellion against control than did female students.

    Clinical reasoning is fundamental to all forms of professional health practice, however it is also difficult to teach and learn because it is complex, tacit, and effectively invisible for students. In this paper we present an approach for teaching clinical reasoning based on making expert thinking visible and accessible to students. Twenty-one experienced allied health clinical educators from three tertiary Australian hospitals attended up to seven action research discussion sessions, where they developed a tentative heuristic of their own clinical reasoning, trialled it with students, evaluated if it helped their students to reason clinically, and then refined it so the heuristic was targeted to developing each student's reasoning skills. Data included participants' written descriptions of the thinking routines they developed and trialed with their students and the transcribed action research discussion sessions. Content analysis was used to summarise this data and categorise themes about teaching and learning clinical reasoning. Two overriding themes emerged from participants' reports about using the 'making thinking visible approach'. The first was a specific focus by participating educators on students' understanding of the reasoning process and the second was heightened awareness of personal teaching styles and approaches to teaching clinical reasoning. We suggest that the making thinking visible approach has potential to assist educators to become more reflective about their clinical reasoning teaching and acts as a scaffold to assist them to articulate their own expert reasoning and for students to access and use.

    The study explored the relationship between the understanding of intention in veiled speech acts and the ability to reason inductively. A total of 39 people with DSM-IV-defined schizophrenia with no behavioural signs and 44 healthy participants performed the Hinting Task, a measure of pragmatic language in which the speaker's intention must be inferred, and a measure of inductive reasoning (Aha! Sentences) in which the meaning of ambiguous nonsocial sentences had to be inferred. The participants also completed measures of general intellectual ability, immediate memory for narrative and social problem-solving ability. A substantial correlation was found between performance on the inductive reasoning task and the Hinting Task in the sample of people with schizophrenia. The same relationship was not seen in the normal control sample. The robust relationship between these two measures in this sample survived when the roles of immediate memory for narrative and intellectual ability were controlled for. Furthermore, the relationship was distinctly more compelling for the patients who were currently ill compared to those in remission. These data suggest that people with schizophrenia use a different strategy to infer the meaning behind pragmatic language than that used by normally functioning adults. It is suggested that a reliance on different, possibly less specialised, skills in this group to perform this simple social inference task underlies their deficient performance on this and other measures of social inference. The fact that the relationship between the tasks in patients in remission is not as robust implies that the use of specialised skills to perform social inference tasks may be compromised most significantly during acute phases.

    The Stern Gerlach experiment has played a central role in the discovery of spin angular momentum and it has also played a pivotal role in elucidating foundational issues in quantum mechanics. Here, we discuss investigation of students' difficulties related to the Stern Gerlach experiment by giving written tests and interviewing advanced undergraduate and graduate students in quantum mechanics. We also discuss preliminary data that suggest that the Quantum Interactive Learning Tutorial (QuILT) related to the Stern Gerlach experiment is helpful in improving students' understanding of these concepts.

    2006-04-01

    In this study were examined associations among physical education teachers' verbal aggressiveness as perceived by students and students' intrinsic motivation and reasons for discipline. The sample consisted of 265 Greek adolescent students who completed four questionnaires, the Verbal Aggressiveness Scale, the Lesson Satisfaction Scale, the Reasons for Discipline Scale, and the Intrinsic Motivation Inventory during physical education classes. Analysis indicated significant positive correlations among students' perceptions of teachers' verbal aggressiveness with pressure/ tension, external reasons, introjected reasons, no reasons, and self-responsibility. Significant negative correlations were noted for students' perceptions of teachers' verbal aggression with lesson satisfaction, enjoyment/interest, competence, effort/importance, intrinsic reasons, and caring. Differences between the two sexes were observed in their perceptions of teachers' verbal aggressiveness, intrinsic motivation, and reasons for discipline. Findings and implications for teachers' type of communication were also discussed and suggestions for research made.

    The GLOBE Program's Student Climate Research Campaign (SCRC) is a two-year campaign focused on empowering students to measure, investigate, and understand the climate system in their local community and around the world. Schools can participate in the campaign via three mechanisms: climate foundations, intensive observing periods (IOPs), and research investigations. Participation in the first year of the SCRC focused on increasing student understanding and awareness of climate. Students in 49 countries participated by joining a quarterly webinar, completing the online climate learning activity, collecting and entering data during IOPs, or completing an online join survey. The year also included a video competition with the theme of Earth Day 2012, as well as a virtual student conference in conjunction with The GLOBE Program's From Learning to Research Project. As the SCRC continues into its second year, the goal is for students to increase their understanding of and ability to conduct scientific research focused on climate. Furthermore, year two of the SCRC seeks to improve students' global awareness by encouraging collaborations among students, teachers and scientists focused on understanding the Earth as a system. In addition to the continuation of activities from year one, year two will have even more webinars offered, two competitions, the introduction of two new IOPs, and a culminating virtual student conference. It is anticipated that this virtual conference will showcase research by students who are enthusiastic and dedicated to understanding climate and mitigating impacts of climate change in their communities. This presentation will highlight examples of how the SCRC is engaging students all over the world in hands-on and locally relevant climate research.

    Susac, Ana; Bubic, Andreja; Vrbanc, Andrija; Planinic, Maja

    2014-01-01

    Algebra typically represents the students' first encounter with abstract mathematical reasoning and it therefore causes significant difficulties for students who still reason concretely. The aim of the present study was to investigate the developmental trajectory of the students' ability to solve simple algebraic equations. 311 participants between the ages of 13 and 17 were given a computerized test of equation rearrangement. Equations consisted of an unknown and two other elements (numbers or letters), and the operations of multiplication/division. The obtained results showed that younger participants are less accurate and slower in solving equations with letters (symbols) than those with numbers. This difference disappeared for older participants (16-17 years), suggesting that they had reached an abstract reasoning level, at least for this simple task. A corresponding conclusion arises from the analysis of their strategies which suggests that younger participants mostly used concrete strategies such as inserting numbers, while older participants typically used more abstract, rule-based strategies. These results indicate that the development of algebraic thinking is a process which unfolds over a long period of time. In agreement with previous research, we can conclude that, on average, children at the age of 15-16 transition from using concrete to abstract strategies while solving the algebra problems addressed within the present study. A better understanding of the timing and speed of students' transition from concrete arithmetic reasoning to abstract algebraic reasoning might help in designing better curricula and teaching materials that would ease that transition.

  20. An investigation of meaningful understanding and effectiveness of the implementation of Piagetian and Ausubelian theories in physics instruction

    Science.gov (United States)

    Williams, Karen Ann

    One section of college students (N = 25) enrolled in an algebra-based physics course was selected for a Piagetian-based learning cycle (LC) treatment while a second section (N = 25) studied in an Ausubelian-based meaningful verbal reception learning treatment (MVRL). This study examined the students' overall (concept + problem solving + mental model) meaningful understanding of force, density/Archimedes Principle, and heat. Also examined were students' meaningful understanding as measured by conceptual questions, problems, and mental models. In addition, students' learning orientations were examined. There were no significant posttest differences between the LC and MVRL groups for students' meaningful understanding or learning orientation. Piagetian and Ausubelian theories explain meaningful understanding for each treatment. Students from each treatment increased their meaningful understanding. However, neither group altered their learning orientation. The results of meaningful understanding as measured by conceptual questions, problem solving, and mental models were mixed. Differences were attributed to the weaknesses and strengths of each treatment. This research also examined four variables (treatment, reasoning ability, learning orientation, and prior knowledge) to find which best predicted students' overall meaningful understanding of physics concepts. None of these variables were significant predictors at the.05 level. However, when the same variables were used to predict students' specific understanding (i.e. concept, problem solving, or mental model understanding), the results were mixed. For forces and density/Archimedes Principle, prior knowledge and reasoning ability significantly predicted students' conceptual understanding. For heat, however, reasoning ability was the only significant predictor of concept understanding. Reasoning ability and treatment were significant predictors of students' problem solving for heat and forces. For density

    Lack of a clear perception of the realities of a career in veterinary medicine could adversely affect young graduates' satisfaction with the profession and their long-term commitment to it. Veterinary students' understanding of a career in practice were explored. Traditional-entry first-year and final-year students, as well as entry-level 'Gateway' (widening participation) students, were invited to complete a questionnaire exploring their pre-university experiences and their understandings of a career in general practice. Broadly speaking, the undergraduate students taking part in the survey (the majority of whom were entry-level students) had a realistic view of average weekly working hours, out-of-hours duties and the development of their remuneration packages over the course of their careers. The main attractions of the profession were working with animals and the perception of a rewarding job. The main concerns were making mistakes and balancing work and home life. The vast majority of students wanted to pursue a career in general practice, and other career opportunities did not appear to be well understood, particularly by entry-level students.

    Yan, Fan

    Understanding chemical reactions is crucial in learning chemistry at all educational levels. Nevertheless, research in science education has revealed that many students struggle to understand chemical processes. Improving teaching and learning about chemical reactions demands that we develop a clearer understanding of student reasoning in this area and of how this reasoning evolves with training in the discipline. Thus, we have carried out a qualitative study using semi-structured interviews as the main data collection tool to explore students reasoning about reaction mechanism and causality. The participants of this study included students at different levels of training in chemistry: general chemistry students (n=22), organic chemistry students (n=16), first year graduate students (n=13) and Ph.D. candidates (n=14). We identified major conceptual modes along critical dimensions of analysis, and illustrated common ways of reasoning using typical cases. Main findings indicate that although significant progress is observed in student reasoning in some areas, major conceptual difficulties seem to persist even at the more advanced educational levels. In addition, our findings suggest that students struggle to integrate important concepts when thinking about mechanism and causality in chemical reactions. The results of our study are relevant to chemistry educators interested in learning progressions, assessment, and conceptual development.

    This study examined the effects of participation in a 1-week, experiential, hands-on learning program on the critical thinking and clinical reasoning skills of occupational therapy students. A quasi-experimental, nonrandomized pre- and post-test design was used with a sample of 25 students. The students had completed three semesters of didactic lecture coursework in a master's level OT educational program prior to participation in a hands-on therapy program for children with hemiplegic cerebral palsy. Changes in critical thinking and clinical reasoning skills were evaluated using the following dependent measures: Self-Assessment of Clinical Reflection and Reasoning (SACRR) and the California Critical Thinking Skills Test (CCTST). Changes in pretest and posttest scores on the SACRR and the CCTST were statistically significant (p>0.05) following completion of the experiential learning program. This study supports the use of hands-on learning to develop clinical reasoning and critical thinking skills in healthcare students, who face ever more diverse patient populations upon entry-level practice. Further qualitative and quantitative investigations are needed to support the results of this study and determine which components of experiential learning programs are essential for developing clinical reasoning and critical thinking skills in future allied health professionals.

  10. Examining Teacher Framing, Student Reasoning, and Student Agency in School-Based Citizen Science

    Science.gov (United States)

    Harris, Emily Mae

    This dissertation presents three interrelated studies examining opportunities for student learning through contributory citizen science (CS), where students collect and contribute data to help generate new scientific knowledge. I draw on sociocultural perspectives of learning to analyze three cases where teachers integrated CS into school science, one third grade, one fourth grade, and one high school Marine Biology classroom. Chapter 2 is a conceptual investigation of the opportunities for students to engage in scientific reasoning practices during CS data collection activities. Drawing on science education literature and vignettes from case studies, I argue that the teacher plays an important role in mediating opportunities for students to engage in investigative, explanatory, and argumentative practices of science through CS. Chapter 3 focuses on teacher framing of CS, how teachers perceive what is going on (Goffman, 1974) and how they communicate that to students as they launch CS tasks. Through analysis of videos and interviews of two upper elementary school teachers, I found that teachers frame CS for different purposes. These framings were influenced by teachers' goals, orientations towards science and CS, planning for instruction, and prior knowledge and experience. Chapter 4 examines how students demonstrate agency with environmental science as they explore their personal interests across their third grade classroom, school garden, and science lab contexts, through the lens of social practice theory (Holland, Lachicotte, Skinner, & Cain, 1998). Through analysis of classroom observations, student interviews, teacher interviews and important moments for three focal students, I found that student agency was enabled and constrained by the different cultures of the classroom, garden, and science lab. Despite affordances of the garden and science lab, the teachers' epistemic authority in the classroom permeated all three contexts, constraining student agency. In

    After articulating 12 concepts for the reasoning component of citizen-level science literacy and restating these as assessable student learning outcomes (SLOs), we developed a valid and reliable assessment instrument for addressing the outcomes with a brief 25-item science literacy concept inventory (SLCI). In this paper, we report the results that we obtained from assessing the citizen-level science literacy of 17,382 undergraduate students, 149 graduate students, and 181 professors. We address only findings at or above the 99.9% confidence level. We found that general education (GE) science courses do not significantly advance understanding of science as a way of knowing. However, the understanding of science's way of knowing does increase through academic ranks, indicating that the extended overall academic experience better accounts for increasing such thinking capacity than do science courses alone. Higher mean institutional SLCI scores correlate closely with increased institutional selectivity, as measured by the institutions' higher mean SAT and ACT scores. Socioeconomic factors of a) first-generation student, b) English as a native language, and c) interest in commitment to a science major are unequally distributed across ethnic groups. These factors proved powerful in accounting for the variations in SLCI scores across ethnicities and genders.

    Verrinder, Joy M; Phillips, Clive J C

    2018-01-01

    With growing understanding of animals' capabilities, and public and organizational pressures to improve animal welfare, moral action by veterinarians and other relevant professionals to address animal issues is increasingly important. Little is known about how their action choices relate to their moral reasoning on animal ethics issues. A moral judgment measure, the VetDIT, with three animal and three non-animal scenarios, was used to investigate the action choices of 619 students in five animal- and two non-animal-related professional programs in one Australian university, and how these related to their moral reasoning based on Personal Interest (PI), Maintaining Norms (MN), or Universal Principles (UP) schemas. Action choices showed significant relationships to PI, MN, and UP questions, and these varied across program groups. Having a previous degree or more experience with farm animals had a negative relationship, and experience with horses or companion animals a positive relationship, with intuitive action choices favoring life and bodily integrity of animals. This study helps to explain the complex relationship between intuitive moral action choices and moral reasoning on animal ethics issues. As a useful research and educational tool for understanding this relationship, the VetDIT can enhance ethical decision making.

    Cirino, Paul T; Morris, Mary K; Morris, Robin D

    2007-03-01

    Semantic retrieval (SR) and executive-procedural (EP), but not visuospatial (VS) skills, have been found to be uniquely predictive of mathematical calculation skills in a sample of clinically referred college students. This study set out to cross-validate these results in an independent sample of clinically referred college students (N = 337) as well as extend them by examination of the contributions of these cognitive domains to math reasoning skills. Results indicate that these cognitive domains were able to predict 30% of the variance in calculation skills and 50% of the variance in math reasoning; however, in both cases, only the domains of semantic retrieval and visuospatial skill contributed uniquely. Differences between studies, and the lack of unique contribution of the EP domain to either type of math skill, may be due to measurement and sampling differences, the degree of shared relations among domains, and the choice of measures that represent the EP domain. Implications and future directions are explored.

    2017-12-01

    This study examines students' reasoning surrounding seemingly contradictory Likert-scale responses within five items in the Colorado Learning Attitudes About Science Survey for Experimental Physics (E-CLASS). We administered the E-CLASS with embedded open-ended prompts, which asked students to provide explanations after making a Likert-scale selection. The quantitative scores on those items showed that our sample of the 216 students enrolled in first year and beyond first year physics courses demonstrated the same trends as previous national data. A qualitative analysis of students' open-ended responses was used to examine common reasoning patterns related to particular Likert-scale responses. When explaining responses to items regarding the role of experiments in confirming known results and also contributing to the growth of scientific knowledge, a common reasoning pattern suggested that confirming known results in a classroom experiment can help with understanding concepts. Thus, physics experiments contribute to students' personal scientific knowledge growth, while also confirming widely known results. Many students agreed that having correct formatting and making well-reasoned conclusions are the main goal for communicating experimental results. Students who focused on sections and formatting emphasized how it enables clear and efficient communication. However, very few students discussed the link between well-reasoned conclusions and effective scientific communication. Lastly, many students argued it was possible to complete experiments without understanding equations and physics concepts. The most common justification was that they could simply follow instructions to finish the lab without understanding. The findings suggest several implications for teaching physics laboratory courses, for example, incorporating some lab activities with outcomes that are unknown to the students might have a significant impact on students' understanding of experiments as an

    2016-09-01

    This study examines expressions of reasoning by some higher achieving 11 to 18 year-old English students responding to a survey consisting of function tasks developed in collaboration with their teachers. We report on 70 students, 10 from each of English years 7-13. Iterative and comparative analysis identified capabilities and difficulties of students and suggested conjectures concerning links between the affordances of the tasks, the curriculum, and students' responses. The paper focuses on five of the survey tasks and highlights connections between informal and formal expressions of reasoning about variables in learning. We introduce the notion of `schooled' expressions of reasoning, neither formal nor informal, to emphasise the role of the formatting tools introduced in school that shape future understanding and reasoning.

    Young people are more likely to have experimented with e-cigarettes (e-cigs) compared with older adults. Few studies identify reasons for experimentation/use of e-cigs among young people; we sought to discover what drives college students to use e-cigs. Undergraduate students (ages 18-23) at four universities in New York State were surveyed. Among e-cig ever users (n=429), reasons for use were examined. A multinomial logistic regression model analyzed the relative risk of reasons for using e-cigs among discontinued, current non-daily and current daily e-cig users. Using e-cigs for enjoyment was associated with current non-daily (RR=2.11, 95% CI=1.18-3.75) and current daily use (RR=19.1, 95% CI=3.71-98.54). Non-daily use was related to use because e-cigs are less toxic than cigarettes (RR=2.80, 95% CI=1.75-4.50). More daily users reported use to quit smoking compared with either non-daily or discontinued users (53.3% vs. 12.2% and 13.3%, respectively; preason. The exception was daily e-cig users, who often reported use for quitting/reduction of smoking. Rather, college students report usage reasons related to affect (e.g. enjoyment). Overall, enjoyment was reported more often than was use for quitting smoking; affective reasons likely play a role in the popularity of e-cigs and should be considered in future assessments of e-cig users.

    Full Text Available Previous physics education research has raised the question of “hidden variables” behind students’ success in learning certain concepts. In the context of the force concept, it has been suggested that students’ reasoning ability is one such variable. Strong positive correlations between students’ preinstruction scores for reasoning ability (measured by Lawson’s Classroom Test of Scientific Reasoning and their learning of forces [measured by the Force Concept Inventory (FCI] have been reported in high school and university introductory courses. However, there is no published research concerning the relation between students’ ability to interpret multiple representations consistently (i.e., representational consistency and their learning of forces. To investigate this, we collected 131 high school students’ pre- and post-test data of the Representational Variant of the Force Concept Inventory (for representational consistency and the FCI. The students’ Lawson pretest data were also collected. We found that the preinstruction level of students’ representational consistency correlated strongly with student learning gain of forces. The correlation (0.51 was almost equal to the correlation between Lawson prescore and learning gain of forces (0.52. Our results support earlier findings which suggest that scientific reasoning ability is a hidden variable behind the learning of forces. In addition, we suggest that students’ representational consistency may also be such a factor, and that this should be recognized in physics teaching.

    Learning quantum mechanics is challenging, even for upper-level undergraduate and graduate students. Research-validated interactive tutorials that build on students' prior knowledge can be useful tools to enhance student learning. We have been investigating student difficulties with quantum mechanics pertaining to the double-slit experiment in various situations that appear to be counterintuitive and contradict classical notions of particles and waves. For example, if we send single electrons through the slits, they may behave as a "wave" in part of the experiment and as a "particle" in another part of the same experiment. Here we discuss the development and evaluation of a research-validated Quantum Interactive Learning Tutorial (QuILT) which makes use of an interactive simulation to improve student understanding of the double-slit experiment and strives to help students develop a good grasp of foundational issues in quantum mechanics. We discuss common student difficulties identified during the development and evaluation of the QuILT and analyze the data from the pretest and post test administered to the upper-level undergraduate and first-year physics graduate students before and after they worked on the QuILT to assess its effectiveness. These data suggest that on average, the QuILT was effective in helping students develop a more robust understanding of foundational concepts in quantum mechanics that defy classical intuition using the context of the double-slit experiment. Moreover, upper-level undergraduates outperformed physics graduate students on the post test. One possible reason for this difference in performance may be the level of student engagement with the QuILT due to the grade incentive. In the undergraduate course, the post test was graded for correctness while in the graduate course, it was only graded for completeness.

    Read this book if you care about students really understanding physics and getting genuine intellectual satisfaction from doing so. Read it too if you fear that this goal is out of reach ? you may be surprised! Laurence Viennot here shows ways to deal with the awkward fact that common sense thinking is often not the same as scientific thinking. She analyses examples of frequent and widespread errors and confusions, which provide a real eye-opener for the teacher. More than that, she shows ways to avoid and overcome them. The book argues against over-emphasis on "fun" applications, demonstratin

    Tobacco-control policy proposals are usually met with opposition on college campuses. Research to understand students' viewpoints about health-related policy proposals and messaging strategies, however, does not exist. This study investigated students' perceptions about a smoke-free policy proposal to help understand their positions of support and opposition and to inform the development of effective messaging strategies. In January 2012, 1,266 undergraduate students from a midwestern university completed an online questionnaire about smoke-free campus policies. Responses were coded and analyzed using Linguistic Inquiry and Word Count software and chi-square, independent-samples t tests, and binary logistic models. Most students who supported a smoke-free policy considered environmental or aesthetic conditions, whereas most opponents used personal freedom frames of thought. Supporters viewed smoking policies in personal terms, and opponents suggested means-ends policy reasoning. Taken together, points of reference and emotions about proposed policies provided insight about participants' perspectives to help inform effective policy advocacy efforts.

    To achieve the goal of scientific literacy, the skills of argumentation have been emphasized in science education during the past decades. But the extent to which students can apply scientific knowledge to their argumentation is still unclear. The purpose of this study was to analyse 80 Swedish upper secondary students' informal argumentation on four socioscientific issues (SSIs) to explore students' use of supporting reasons and to what extent students used scientific knowledge in their arguments. Eighty upper secondary students were asked to express their opinions on one SSI topic they chose through written reports. The four SSIs in this study include global warming, genetically modified organisms (GMO), nuclear power, and consumption. To analyse students' supporting reasons from a holistic view, we used the SEE-SEP model, which links the six subject areas of sociology/culture (So), environment (En), economy (Ec), science (Sc), ethics/morality (Et) and policy (Po) connecting with three aspects, knowledge, value and personal experience (KVP). The results showed that students used value to a greater extent (67%) than they did scientific knowledge (27%) for all four SSI topics. According to the SEE-SEP model, the distribution of supporting reasons generated by students differed among the SSI topics. Also, some alternative concepts were disclosed in students' arguments. The implications for research and education are discussed.

    In the Netherlands, hundreds of students register annually for a nursing programme, but not all of these students manage to complete their training. The main aim of this study was to examine which factors affect student nurses' decision to leave or complete their programme. The study used an exploratory descriptive design, employing a qualitative phenomenological approach. Student nurses (n=17) at the beginning of their third year of the four-year Bachelor's programme. Data were collected at four Universities of Applied Sciences in the Netherlands, from December 2013 to January 2014. Semi-structured interviews were used to collect the data, using an interview guide. The main reasons for students to become nurses were the caring aspect, personal experiences with healthcare, role models in their immediate environment, and job opportunities. They had both altruistic and professional perceptions of their profession. Reasons for attrition were strongly related to the training programme and to their clinical placements, in particular the perceived lack of support from mentors and team. Feelings of being welcomed and working in a nice team proved to be more important reasons for completing the programme than the specific clinical field. Student nurses started their studies with many dreams, such as caring for people and having the opportunity to deliver excellent nursing care. When their expectations were not met, their dreams became disappointments which caused them to consider stopping and even to leave (attrition). The role of lecturers and mentors seems invaluable in protecting and guiding students through their programme and placements. Optimal cooperation between lecturers and mentors is of paramount importance to retain student nurses in their training programmes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Caffeine intake in a convenience sample of U.S. college students (N = 1248) was surveyed at five geographically-dispersed United States (U.S.) universities. Intake from coffee, tea, soft drinks, energy drinks, gums, and medications was assessed. Associations between caffeine intake and demographic variables including sex, age, race/ethnicity, family income, general health, exercise, weight variables and tobacco use were examined. Reasons for use of caffeine-containing products were assessed. Caffeine, in any form, was consumed by 92% of students in the past year. Mean daily caffeine consumption for all students, including non-consumers, was 159 mg/d with a mean intake of 173 mg/d among caffeine users. Coffee was the main source of caffeine intake in male (120 mg/d) and female (111 mg/d) consumers. Male and female students consumed 53 vs. 30 mg/d of caffeine in energy drinks, respectively, and 28% consumed energy drinks with alcohol on at least one occasion. Students provided multiple reasons for caffeine use including: to feel awake (79%); enjoy the taste (68%); the social aspects of consumption (39%); improve concentration (31%); increase physical energy (27%); improve mood (18%); and alleviate stress (9%). As in the general U.S. population, coffee is the primary source of caffeine intake among the college students surveyed. Energy drinks provide less than half of total daily caffeine intake but more than among the general population. Students, especially women, consume somewhat more caffeine than the general population of individuals aged 19-30 y but less than individuals aged 31-50 y. Published by Elsevier Ltd.

    In view of the general support for organ donation but low registration rate in Hong Kong, the present research attempted to understand the attitude-behavior inconsistency by identifying the underlying beliefs for organ donation through employing the theory of reasoned action. A qualitative approach using semi-structured focus groups was adopted and 19 students from three universities in Hong Kong participated; 10 constructs were identified: attitude, subjective norm, helping, continuation, contribution, body intact, distrust to the medical system, indifference to organ donation, negative affect, and family burden. Findings suggested that their attitudes toward organ donation were of both the cognitive and affective nature; subjective norm of family, friends, and people they respect were identified as influential to students' views on organ donation. The study provided insight in promoting organ donation, that the cognitive concerns about keeping the body intact, and the negative affects introduced should also be addressed.

  18. Theoretical and practical significance of formal reasoning

    Science.gov (United States)

    Linn, Marcia C.

    Piaget's theory has profoundly influenced science education research. Following Piaget, researchers have focused on content-free strategies, developmentally based mechanisms, and structural models of each stage of reasoning. In practice, factors besides those considered in Piaget's theory influence whether or not a theoretically available strategy is used. Piaget's focus has minimized the research attention placed on what could be called practical factors in reasoning. Practical factors are factors that influence application of a theoretically available strategy, for example, previous experience with the task content, familiarity with task instructions, or personality style of the student. Piagetian theory has minimized the importance of practical factors and discouraged investigation of (1) the role of factual knowledge in reasoning, (2) the diagnosis of specific, task-based errors in reasoning, (3) the influence of individual aptitudes on reasoning (e.g., field dependence-independence), and (4) the effect of educational interventions designed to change reasoning. This article calls for new emphasis on practical factors in reasoning and suggests why research on practical factors in reasoning will enhance our understanding of how scientific reasoning is acquired and of how science education programs can foster it.

  19. Mechanisms influencing student understanding on an outdoor guided field trip

    Science.gov (United States)

    Caskey, Nourah Al-Rashid

    Field trips are a basic and important, yet often overlooked part of the student experience. They provide the opportunity to integrate real world knowledge with classroom learning and student previous personal experiences. Outdoor guided field trips leave students with an increased understanding, awareness and interest and in science. However, the benefits of this experience are ambiguous at best (Falk and Balling, 1982; Falk and Dierking, 1992; Kisiel, 2006.) Students on an outdoor guided field trip to a local nature park experienced a significant increase in their understanding of the rock cycle. The changes in the pre-field trip test and the post-field trip test as well as their answers in interviews showed a profound change in the students' understanding and in their interest in the subject matter. The use of the "student's voice" (Bamberger and Tal, 2008) was the motivation for data analysis. By using the students' voice, I was able to determine the mechanisms that might influence their understanding of a subject. The central concepts emerging from the data were: the outdoor setting; the students' interest; the social interaction. From these central concepts, a conceptual model was developed. The outdoor setting allows for the freedom to explore, touch, smell and movement. This, in turn, leads to an increased interest in subject matter. As the students are exploring, they are enjoying themselves and become more open to learning. Interest leads to a desire to learn (Dewey, 1975). In addition to allowing the freedom to explore and move, the outdoor setting creates the condition for social interaction. The students talk to each other as they walk; they have in-depth discourse regarding the subject matter---with the teachers, each other and with the guides. The guides have an extremely important role in the students' learning. The more successful guides not only act as experts, but also adjust to the students' needs and act or speak accordingly. The

    We examined generational differences in reasons for attending college among a nationally representative sample of college students (N = 8 million) entering college between 1971-2014. We validated the items on reasons for attending college against an established measure of extrinsic and intrinsic values among college students in 2014 (n = 189). Millennials (in college 2000s-2010s) and Generation X (1980s-1990s) valued extrinsic reasons for going to college ("to make more money") more, and anti-extrinsic reasons ("to gain a general education and appreciation of ideas") less than Boomers when they were the same age in the 1960s-1970s. Extrinsic reasons for going to college were higher in years with more income inequality, college enrollment, and extrinsic values. These results mirror previous research finding generational increases in extrinsic values begun by GenX and continued by Millennials, suggesting that more recent generations are more likely to favor extrinsic values in their decision-making.

    The goal of this study was to determine differences in moral judgment among students in medical school. This cross-sectional study involved students currently enrolled in undergraduate medical education. Recruited via email, 192 students took an online version of the Defining Issues Test to determine their current stage of moral judgment, as well as their percentage of postconventional thought. Independent variables included year of graduation, which indicated curriculum completion as well as participation in a professionalism course. Data was analyzed primarily using One-Way Analysis of Variance. Of the 192 participants, 165 responses were utilized. ANOVA showed no significant differences in moral judgment between or among any of the student cohorts, which were grouped by year of matriculation. Comparisons included students in the four years of medical school, divided by graduation year; students about to graduate (n=30) vs. those still in school (n=135); and students who had participated in a course in professionalism (n=91) vs. those who had not (n=74). These results demonstrate a lack of evolution in the moral reasoning of medical students and raise the issue of what might stimulate positive changes in moral judgment during the medical school experience.

  4. The Importance of Spatial Reasoning Skills in Undergraduate Geology Students and the Effect of Weekly Spatial Skill Trainings

    2016-04-01

    Spatial reasoning is a key skill for student success in STEM disciplines in general and for students in geosciences in particular. However, spatial reasoning is neither explicitly trained, nor evenly distributed, among students and by gender. This uneven playing field allows some students to perform geoscience tasks easily while others struggle. A lack of spatial reasoning skills has been shown to be a barrier to success in the geosciences, and for STEM disciplines in general. Addressing spatial abilities early in the college experience might therefore be effective in retaining students, especially females, in STEM disciplines. We have developed and implemented a toolkit for testing and training undergraduate student spatial reasoning skills in the classroom. In the academic year 2014/15, we studied the distribution of spatial abilities in more than 700 undergraduate Geology students from 4 introductory and 2 upper level courses. Following random assignment, four treatment groups received weekly online training and intermittent hands-on trainings in spatial thinking while four control groups only participated in a pre- and a posttest of spatial thinking skills. In this presentation we summarize our results and describe the distribution of spatial skills in undergraduate students enrolled in geology courses. We first discuss the factors that best account for differences in baseline spatial ability levels, including general intelligence (using standardized test scores as a proxy), major, video gaming, and other childhood play experiences, which help to explain the gender gap observed in most research. We found a statistically significant improvement of spatial thinking still with large effect sizes for the students who received the weekly trainings. Self-report data further shows that students improve their spatial thinking skills and report that their improved spatial thinking skills increase their performance in geoscience courses. We conclude by discussing the

    Full Text Available A study was conducted in Vellore district of Tamil Nadu state to understand the learning styles of students. The term learning style refers to the way or method or approach by which a student learns. The study explored the possible learning style variations among agricultural, horticultural, engineering and arts & science students and their association with academic achievement. One hundred and twelve students were randomly selected from the four streams and their learning styles were analyzed. In the agricultural and horticultural streams, a majority of the students were auditory learners. They were also found to be predominantly unimodal learners. Overall, it was found that majority of the students were visual learners followed by auditory and kinesthetic style. The highest percentage of kinesthetic learners was found among engineering students. Trimodal learners scored the highest mean percentage of marks. The influence of learning styles on the academic achievements of the students did not show a significant relationship.

    Although some tests for clinical reasoning assessment are now available, the theories of medical expertise have not played a major role in this filed. In this paper, illness script theory was chose as a theoretical framework and contemporary clinical reasoning tests were put together based on this theoretical model. This paper is a qualitative study performed with an action research approach. This style of research is performed in a context where authorities focus on promoting their organizations' performance and is carried out in the form of teamwork called participatory research. Results are presented in four parts as basic concepts, clinical reasoning assessment, test framework, and scoring. we concluded that no single test could thoroughly assess clinical reasoning competency, and therefore a battery of clinical reasoning tests is needed. This battery should cover all three parts of clinical reasoning process: script activation, selection and verification. In addition, not only both analytical and non-analytical reasoning, but also both diagnostic and management reasoning should evenly take into consideration in this battery. This paper explains the process of designing and implementing the battery of clinical reasoning in the Olympiad for medical sciences students through an action research.

  13. A Framework for Understanding Physics Students' Computational Modeling Practices

    Science.gov (United States)

    Lunk, Brandon Robert

    With the growing push to include computational modeling in the physics classroom, we are faced with the need to better understand students' computational modeling practices. While existing research on programming comprehension explores how novices and experts generate programming algorithms, little of this discusses how domain content knowledge, and physics knowledge in particular, can influence students' programming practices. In an effort to better understand this issue, I have developed a framework for modeling these practices based on a resource stance towards student knowledge. A resource framework models knowledge as the activation of vast networks of elements called "resources." Much like neurons in the brain, resources that become active can trigger cascading events of activation throughout the broader network. This model emphasizes the connectivity between knowledge elements and provides a description of students' knowledge base. Together with resources resources, the concepts of "epistemic games" and "frames" provide a means for addressing the interaction between content knowledge and practices. Although this framework has generally been limited to describing conceptual and mathematical understanding, it also provides a means for addressing students' programming practices. In this dissertation, I will demonstrate this facet of a resource framework as well as fill in an important missing piece: a set of epistemic games that can describe students' computational modeling strategies. The development of this theoretical framework emerged from the analysis of video data of students generating computational models during the laboratory component of a Matter & Interactions: Modern Mechanics course. Student participants across two semesters were recorded as they worked in groups to fix pre-written computational models that were initially missing key lines of code. Analysis of this video data showed that the students' programming practices were highly influenced by

    Firat, Mehmet

    2017-04-01

    In the past, distance education was used as a method to meet the educational needs of citizens with limited options to attend an institution of higher education. Nowadays, it has become irreplaceable in higher education thanks to developments in instructional technology. But the question of why students choose distance education is still important. The purpose of this study was to determine Turkish students' reasons for choosing distance education and to investigate how these reasons differ depending on their financial circumstances. The author used a Chi squared Automatic Interaction Detector (CHAID) analysis to determine 18,856 Turkish students' reasons for choosing distance education. Results of the research revealed that Turkish students chose distance education not because of geographical limitations, family-related problems or economic difficulties, but for such reasons as already being engaged in their profession, increasing their knowledge, and seeking promotion to a better position.

  16. Exploring the Relationship between Students' Understanding of Conventional Time and Deep (Geologic) Time

    Science.gov (United States)

    Cheek, Kim A.

    2013-07-01

    Many geologic processes occur in the context of geologic or deep time. Students of all ages demonstrate difficulty grasping this fundamental concept which impacts their ability to acquire other geoscience concepts. A concept of deep time requires the ability to sequence events on an immense temporal scale (succession) and to judge the durations of geologic processes based on the rates at which they occur. The twin concepts of succession and duration are the same ideas that underlie a concept of conventional time. If deep time is an extension of conventional time and not qualitatively different from it, students should display similar reasoning patterns when dealing with analogous tasks over disparate temporal periods. Thirty-five US students aged 13-24 years participated in individual task-based interviews to ascertain how they thought about succession and duration in conventional and deep time. This is the first attempt to explore this relationship in the same study in over 30 years. Most students successfully completed temporal succession tasks, but there was greater variability in responses on duration tasks. Conventional time concepts appear to impact how students reason about deep time. The application of spatial reasoning to temporal tasks sometimes leads to correct responses but in other instances does not. Implications for future research and teaching strategies are discussed.

  17. Towards a probabilistic definition of entropy: An investigation of the effects of a new curriculum on students' understanding of thermodynamics

    Science.gov (United States)

    Colon-Garcia, Evy B.

    Thermodynamics is a vital tool in understanding why reactions happen; nevertheless, it is often considered a difficult topic. Prior studies have shown that students struggle with fundamental thermodynamic concepts such as entropy, enthalpy and Gibbs energy even in upper level physical chemistry courses. Thermodynamics, as a general chemistry topic, can be more math-intensive than other topics such as bonding or intermolecular forces. As a result, it is possible for students to get lost in the algorithms and overlook the important underlying theoretical concepts. Students' difficulties in understanding thermodynamics may be contributing to their inability to explain phenomena such as phase changes and manipulations of equilibrium systems. Current chemistry curricula split the thermodynamic chapters over a span of two semesters as well as splitting it over different units. This division fails to make explicit the connection between Enthalpy, Entropy and Gibbs Energy and how they affect how and why every reaction or process happens. The reason for this division of topics is not based on any educational research rather than opinions as to what will not overwhelm the students. Additionally, students who take only one semester of General Chemistry will leave without being instructed in what is considered to be one of the most fundamental concepts in Chemistry, Thermodynamics. Chemistry, Life, the Universe and Everything (CLUE) is a general chemistry course developed with the explicit goal of addressing the major obstacles that inhibit students from acquiring an appreciation and mastery of the chemical principles upon which other sciences depend. Using a control and treatment group, the effectiveness of this new curriculum was evaluated for two main aspects: 1. What is students' understanding of entropy?, 2. Can an alternative instructional approach to teaching Thermodynamics (Chemistry, Life, the Universe and Everything - CLUE) improve students' understanding of Entropy

  19. Does Conceptual Understanding of Limit Partially Lead Students to Misconceptions?

    2017-09-01

    This article talks about the result of preliminary research of my dissertation, which will investigate student’s retention of conceptual understanding. In my preliminary research, I surveyed 73 students of mathematics education program by giving some questions to test their retention of conceptual understanding of limits. Based on the results of analyzing of students’ answers I conclude that most of the students have problems with their retention of conceptual understanding and they also have misconception of limits. The first misconception I identified is that students always used the substitution method to determine a limit of a function at a point, but they did not check whether the function is continue or not at the point. It means that they only use the substitution theorem partially, because they do not consider that the substitution theorem \\mathop{{lim}}\\limits\\text{x\\to \\text{c}}f(x)=f(c) works only if f(x) is defined at χ = c. The other misconception identified is that some students always think there must be available of variables χ in a function to determine the limit of the function. I conjecture that conceptual understanding of limit partially leads students to misconceptions.

    Reasoning skill is needed for everyone to face globalization era, because every person have to be able to manage and use information from all over the world which can be obtained easily. Statistical reasoning skill is the ability to collect, group, process, interpret, and draw conclusion of information. Developing this skill can be done through various levels of education. However, the skill is low because many people assume that statistics is just the ability to count and using formulas and so do students. Students still have negative attitude toward course which is related to research. The purpose of this research is analyzing students’ misconception in descriptive statistic course toward the statistical reasoning skill. The observation was done by analyzing the misconception test result and statistical reasoning skill test; observing the students’ misconception effect toward statistical reasoning skill. The sample of this research was 32 students of math education department who had taken descriptive statistic course. The mean value of misconception test was 49,7 and standard deviation was 10,6 whereas the mean value of statistical reasoning skill test was 51,8 and standard deviation was 8,5. If the minimal value is 65 to state the standard achievement of a course competence, students’ mean value is lower than the standard competence. The result of students’ misconception study emphasized on which sub discussion that should be considered. Based on the assessment result, it was found that students’ misconception happen on this: 1) writing mathematical sentence and symbol well, 2) understanding basic definitions, 3) determining concept that will be used in solving problem. In statistical reasoning skill, the assessment was done to measure reasoning from: 1) data, 2) representation, 3) statistic format, 4) probability, 5) sample, and 6) association.

    2017-09-01

    This article reports on the effect of using a diagram to develop primary students' conceptual understanding about electric circuits. Diagrammatic representations of electric circuits are used for teaching and assessment despite the absence of research on their pedagogical effectiveness with young learners. Individual interviews were used to closely analyse Years 3 and 5 (8-11-year-old) students' explanations about electric circuits. Data was collected from 20 students in the same school providing pre-, post- and delayed post-test dialogue. Students' thinking about electric circuits and changes in their explanations provide insights into the role of diagrams in understanding science concepts. Findings indicate that diagram interaction positively enhanced understanding, challenged non-scientific views and promoted scientific models of electric circuits. Differences in students' understanding about electric circuits were influenced by prior knowledge, meta-conceptual awareness and diagram conventions including a stylistic feature of the diagram used. A significant finding that students' conceptual models of electric circuits were energy rather than current based has implications for electricity instruction at the primary level.

    2015-01-01

    Full Text Available As society’s needs for quantitative skills become more prevalent, college graduates require quantitative skills regardless of their career choices. Therefore, it is important that institutions assess students’ engagement in quantitative activities during college. This study chronicles the process taken by the National Survey of Student Engagement (NSSE to develop items that measure students’ participation in quantitative reasoning (QR activities. On the whole, findings across the quantitative and qualitative analyses suggest good overall properties for the developed QR items. The items show great promise to explore and evaluate the frequency with which college students participate in QR-related activities. Each year, hundreds of institutions across the United States and Canada participate in NSSE, and, with the addition of these new items on the core survey, every participating institution will have information on this topic. Our hope is that these items will spur conversations on campuses about students’ use of quantitative reasoning activities.

    2007-12-01

    Full Text Available Taking as point of departure Hegelrsquo;s early reflections on his historical present, this essay examines the relationship between dialectical reason and the activity of the understanding in generating contradiction. Dialecticmdash;as logic and methodmdash;is Hegelrsquo;s attempt at a philosophical comprehension of the conflicts and the deep changes of his contemporary world. This idea of dialectic as logic of historical transformation guides the development of consciousness in the emPhenomenology of Spirit/em. Since my claim is that the dialectic of consciousness and its capacity of overcoming contradiction are rooted in the historical situation of 1807, the question is raised of what would be the specific problems encountered by consciousness in our contemporary worldmdash;in 2007. What are the challenges posed by our globalized world to a phenomenology of contemporary spirit; and what is the role that contradiction and dialectic play in the understanding of our own historical present?

    Full Text Available This study aimed to verify the relation between religiousness and the moral reasoning of Accounting undergraduate students. To achieve that, the religiousness and moral reasoning of the subjects were first described and, subsequently, correlated. In order to measure religiousness, the Faith Maturity Scale developed by Benson, Donahue, Erickson (1993 was used. The measuring of moral reasoning, on the other hand, was carried out using the Defining Issues Test -2 created by Rest and Narvaez (1988. The sample was drawn from 67 Accounting undergraduate students, in their last semester of College, from two universities in Paraíba, and the internal consistency reliability test of the research instruments was carried out using the model defined by Cronbach (1951. To verify whether there is a relation between religiousness and moral reasoning, the Spearman (rs non-parametric correlation coefficient was used. The main results revealed that the majority of the subjects have their faith classified as integrated. As for moral reasoning, most of the subjects were classified in the level of maintaining the norms, which indicates that, for the bulk of subjects, the conformity to the laws and norms is the most important thing. Still on moral reasoning, it has been shown that, when analysed by type, most individuals fall into type 2 (personal interest, but in transition, with the important observation that individuals of this type, when involved in moral dilemmas, tend to prioritise their own interests. With regards to the analysis of the relation between religiousness and moral reasoning, it’s been demonstrated that there is no relevant evidence that confirms it, since the relation between both variables was not significant.

  13. Investigation of the relationship between students' problem solving and conceptual understanding of electricity

    Science.gov (United States)

    Cobanoglu Aktan, Derya

    The purpose of this study was to investigate the relationship between students' qualitative problem solving and conceptual understanding of electricity. For the analysis data were collected from observations of group problem solving, from their homework artifacts, and from semi-structured interviews. The data for six undergraduate students were analyzed by qualitative research methods. The students in the study were found to use tools (such as computer simulations and formulas) differently from one another, and they made different levels of interpretations for the electricity representations. Consequently each student had different problem solving strategies. The students exhibited a wide range of levels of understanding of the electricity concepts. It was found that students' conceptual understandings and their problem solving strategies were closely linked with one another. The students who tended to use multiple tools to make high level interpretations for representations to arrive at a single solution exhibited a higher level of understanding than the students who tended to use tools to make low level interpretations to reach a solution. This study demonstrates a relationship between conceptual understanding and problem solving strategies. Similar to the results of the existing research on students' quantitative problem solving, it was found that students were able to give correct answers to some problems without fully understanding the concepts behind the problem. However, some problems required a conceptual understanding in order for a student to arrive at a correct answer. An implication of this study is that careful selection of qualitative questions is necessary for capturing high levels of conceptual understanding. Additionally, conceptual understanding among some types of problem solvers can be improved by activities or tasks that can help them reflect on their problem solving strategies and the tools they use.

    Gregory, David; Harrowing, Jean; Lee, Bonnie; Doolittle, Lisa; O'Sullivan, Patrick S

    2010-01-01

    In this qualitative study, we explored how students understood "culture." Participants defined culture and wrote narratives regarding specific cultural encounters. The sample comprised both nursing (n=14) and non-nursing (n=8) students to allow for comparison groups. Content analysis of the narratives revealed two broad paradigms of cultural understanding: essentialist and constructivist. Essentialist narratives comprised four themes: determinism (culture defied individual resistance); relativism (the possibility of making value judgments disappeared); Othering (culture was equated to exotica, and emphasized difference); and, reductionism (personhood was eclipsed by culture). In contrast, the constructivist narratives were characterized by influence (non-determinism), dynamism (culture was dynamic and evolutionary); and, relationship-building. The unintended negative consequences of essentialist notions of culture were revealed in the nursing students' narratives. Pedagogy is implicated in nursing students' essentialized understanding of culture.

    Doenst, Torsten; Bugger, Heiko; Schwarzer, Michael; Faerber, Gloria; Borger, Michael A; Mohr, Friedrich W

    2008-05-01

    It is the principal goal of cardiac surgeons to improve or reinstate contractile function with, through or after a surgical procedure on the heart. Uninterrupted contractile function of the heart is irrevocably linked to the uninterrupted supply of energy in the form of ATP. Thus, it would appear natural that clinicians interested in myocardial contractile function are interested in the way the heart generates ATP, i.e. the processes generally referred to as energy metabolism. Yet, it may appear that the relevance of energy metabolism in cardiac surgery is limited to the area of cardioplegia, which is a declining research interest. It is the goal of this review to change this trend and to illustrate the role and the therapeutic potential of metabolism and metabolic interventions for management. We present three compelling reasons why cardiac metabolism is of direct, practical interest to the cardiac surgeon and why a better understanding of energy metabolism might indeed result in improved surgical outcomes: (1) To understand cardioplegic arrest, ischemia and reperfusion, one needs a working knowledge of metabolism; (2) hyperglycemia is an underestimated and modifiable risk factor; (3) acute metabolic interventions can be effective in patients undergoing cardiac surgery.

  20. The Effects of Emotive Reasoning on Secondary School Students' Decision-Making in the Context of Socioscientific Issues

    Science.gov (United States)

    Powell, Wardell A.

    The discrepancy between what students are being taught within K-12 science classrooms and what they experience in the real world has been well documented. This study sought to explore the ways a high school biology curriculum, which integrates socioscientific issues, impacts students' emotive reasoning and their ability to evaluate evidence, make informed decisions on contemporary scientific dilemmas, and integrate scientific content knowledge in their reasoning on SSI. Both quantitative and qualitative methods were used to examine differences within and between an SSI treatment group and a comparison group as well as individual differences among students' responses over a semester of high school biology. Results indicated students used emotions largely to evaluate evidence and make decisions on contentious scientific dilemmas. In addition, the results showed students used newly gained scientific content knowledge to make logical predictions on contentious scientific issues. Statistical significance was found between groups of students in regard to their interest in the use of embryonic stem cell treatments to restore rats' vision, as well as students' abilities to evaluate evidence. Theoretical implications regarding the use of SSI in the classroom are presented.

    Electronic cigarettes (e-cigarettes) were the most commonly used tobacco product among U.S. middle school and high school students in 2016 (1). CDC and the Food and Drug Administration (FDA) analyzed data from the 2016 National Youth Tobacco Survey (NYTS) to assess self-reported reasons for e-cigarette use among U.S. middle school (grades 6-8) and high school (grades 9-12) student e-cigarette users. Among students who reported ever using e-cigarettes in 2016, the most commonly selected reasons for use were 1) use by "friend or family member" (39.0%); 2) availability of "flavors such as mint, candy, fruit, or chocolate" (31.0%); and 3) the belief that "they are less harmful than other forms of tobacco such as cigarettes" (17.1%). The least commonly selected reasons were 1) "they are easier to get than other tobacco products, such as cigarettes" (4.8%); 2) "they cost less than other tobacco products such as cigarettes" (3.2%); and 3) "famous people on TV or in movies use them" (1.5%). Availability of flavors as a reason for use was more commonly selected by high school users (32.3%) than by middle school users (26.8%). Efforts to prevent middle school and high school students from initiating the use of any tobacco product, including e-cigarettes, are important to reduce tobacco product use among U.S. youths (2).

  5. The understanding of the students about the nature of light in recursive curriculum

    2010-01-01

    Full Text Available We report an inquiry on the development of students' understanding about the nature of light. The study happened in a learning environment with a recursive and spiral Physics syllabus. We investigated the change in students' understanding about the nature of light during their 3rd year in High School, and the level of understanding about this subject achieved by students at the end of this year. To assess the students' understanding, we developed an open questionnaire form and a set of hierarchical categories, consisting of five different models about the nature of light. The questionnaire was used to access the students´ understanding at the beginning and at the end of the third level of the recursive curriculum. The results showed that students have a high level of prior knowledge, and also that the Physics learning they experienced had enhanced their understanding, despite the effects are not verified in all the Physics classes. By the end of the third year, most of the students explain the nature of light using or a corpuscular electromagnetic model or a dual electromagnetic model, but some students use these models with inconsistencies in their explanations.

Rather, it is focused on students' abilities to apply basic concepts about photosynthesis by reasoning with a coordinated set of practices based on a few scientific principles: conservation of matter, conservation of energy, and the hierarchical nature of biological systems. Data on students' responses to the cluster items and uses of some of the questions in multiple-choice, multiple-true/false, and essay formats are compared. A cross-over study indicates that the multiple-true/false format shows promise as a machine-gradable format that identifies students who have a mixture of accurate and inaccurate ideas. In addition, interviews with students about their choices on three multiple-choice questions reveal the fragility of students' understanding. Collectively, the data show that many undergraduates lack both a basic understanding of the role of photosynthesis in plant metabolism and the ability to reason with scientific principles when learning new content. Implications for instruction are discussed.

    Creating a classroom environment that fosters a productive learning experience and engages students in the learning process is a complex endeavor. A classroom environment is dynamic and requires a unique synergy among students, teacher, classroom artifacts and events to achieve robust understanding and knowledge integration. This dissertation addresses this complex issue by developing, implementing, and investigating the simple machines learning environment (SIMALE) to support students' mechanical reasoning and understanding. SIMALE was designed to support reflection, collaborative learning, and to engage students in generative learning through multiple representations of concepts and successive experimentation and design activities. Two key components of SIMALE are an original web-based software tool and hands-on Lego activities. A research study consisting of three treatment groups was created to investigate the benefits of hands-on and web-based computer activities on students' analytic problem solving ability, drawing/modeling ability, and conceptual understanding. The study was conducted with two populations of students that represent a diverse group with respect to gender, ethnicity, academic achievement and social/economic status. One population of students in this dissertation study participated from the Mathematics, Engineering, and Science Achievement (MESA) program that serves minorities and under-represented groups in science and mathematics. The second group was recruited from the Academic Talent Development Program (ATDP) that is an academically competitive outreach program offered through the University of California at Berkeley. Results from this dissertation show success of the SIMALE along several dimensions. First, students in both populations achieved significant gains in analytic problem solving ability, drawing/modeling ability, and conceptual understanding. Second, significant differences that were found on pre-test measures were eliminated

    Aleong, Richard James Chung Mun

    There is a societal need for design education to prepare holistic engineers with the knowledge, skills, and attitudes to innovate and compete globally. Design skills are paramount to the espoused values of higher education, as institutions of higher learning strive to develop in students the cognitive abilities of critical thinking, problem solving, and creativity. To meet these interests from industry and academia, it is important to advance the teaching and learning of engineering design. This research aims to understand how engineering students learn and think about design, as a way for engineering educators to optimize instructional practice and curriculum development. Qualitative research methodology was used to investigate the meaning that engineering students' ascribe to engineering design. The recruitment of participants and corresponding collection of data occurred in two phases using two different data collection techniques. The first phase involved the distribution of a one-time online questionnaire to all first year, third year, and fourth year undergraduate engineering students at three Canadian Universities. After the questionnaire, students were asked if they would be willing to participate in the second phase of data collection consisting of a personal interview. A total of ten students participated in interviews. Qualitative data analysis procedures were conducted on students' responses from the questionnaire and interviews. The data analysis process consisted of two phases: a descriptive phase to code and categorize the data, followed by an interpretative phase to generate further meaning and relationships. The research findings present a conceptual understanding of students' descriptions about engineering design, structured within two educational orientations: a learning studies orientation and a curriculum studies orientation. The learning studies orientation captured three themes of students' understanding of engineering design: awareness

  12. A cognitive framework for analyzing and describing introductory students' use and understanding of mathematics in physics

    Tuminaro, Jonathan

    Many introductory, algebra-based physics students perform poorly on mathematical problem solving tasks in physics. There are at least two possible, distinct reasons for this poor performance: (1) students simply lack the mathematical skills needed to solve problems in physics, or (2) students do not know how to apply the mathematical skills they have to particular problem situations in physics. While many students do lack the requisite mathematical skills, a major finding from this work is that the majority of students possess the requisite mathematical skills, yet fail to use or interpret them in the context of physics. In this thesis I propose a theoretical framework to analyze and describe students' mathematical thinking in physics. In particular, I attempt to answer two questions. What are the cognitive tools involved in formal mathematical thinking in physics? And, why do students make the kinds of mistakes they do when using mathematics in physics? According to the proposed theoretical framework there are three major theoretical constructs: mathematical resources, which are the knowledge elements that are activated in mathematical thinking and problem solving; epistemic games, which are patterns of activities that use particular kinds of knowledge to create new knowledge or solve a problem; and frames, which are structures of expectations that determine how individuals interpret situations or events. The empirical basis for this study comes from videotaped sessions of college students solving homework problems. The students are enrolled in an algebra-based introductory physics course. The videotapes were transcribed and analyzed using the aforementioned theoretical framework. Two important results from this work are: (1) the construction of a theoretical framework that offers researchers a vocabulary (ontological classification of cognitive structures) and grammar (relationship between the cognitive structures) for understanding the nature and origin of

    This study examined reasoning and problem solving by 182 12th grade students in Taiwan when considering a socio-scientific issue regarding the use of nuclear energy. Students' information preferences, background characteristics, and eleven everyday scientific thinking skills were scrutinized. It was found most participants displayed a willingness to take into account both scientific and social information in reasoning the merits of a proposed construction of a nuclear power plant. Students' reasoning scores obtained from the "information reasoning style" test ranged from -0.5 to 1.917. And, the distribution was approximately normal with mean and median at around 0.5. For the purpose of categorization, students whose scores were within one standard deviation from the mean were characterized as having a "equally disposed" reasoning style. One hundred and twenty-five subjects, about 69%, belonged to this category. Students with scores locating at the two tails of the distribution were assigned to either the "scientifically oriented" or the "socially oriented" reasoning category. Among 23 background characteristics investigated using questionnaire data and ANOVA statistical analysis, only students' science performance and knowledge about nuclear energy were statistically significantly related to their information reasoning styles (p religion, and the political party preference. For everyday scientific thinking skills, interview data showed that both "scientifically oriented" students and those who were categorized as "equally disposed to using scientific and social scientific sources of data" displayed higher frequencies than "socially oriented" ones in using these skills, except in the use of the "multidisciplinary thinking" skill. Among the 11 skills assessed, the "scientifically oriented" students outperformed the "equally disposed" ones only in the use of 3 thinking skills; namely, searching for or recalling scientific concepts/evidence, recognizing and evaluating

    Full Text Available This paper analyzes the reasoning processes in mathematical tasks of two students in the 9th year of elementary school and two students in the second year of college. It also focuses the representation and meaningfulness, given their close relation with the mathematical reasoning. Results presented are based on two qualitative and interpretive studies which resort to several data sources. These results show that mastering of the algebraic language by the students in the 9th year is still insufficient to promptly solve the problems proposed, which does not occur with the college students though. All students use inductive initial strategies. However, one of the students in the 9th year and both college students revealed clearly their capability to reason deductively. The signification levels vary considerably, and several students have shown skills to build or mobilize relevant meanings. The model of analysis presented, articulating reasoning, representations and meaningfulness proved itself a promising tool to study the students’ reasoning processes.

    The purpose of the current study was to investigate the effectiveness of interacting with animations using mobile devices on grade 12 students' spatial and reasoning abilities. The study took place in a grade 12 context in Oman. A quasi-experimental design was used with an experimental group of 32 students and a control group of 28 students. The experimental group studied chemistry using mobile tablets that had a digital instructional package with different animation and simulations. There was one tablet per student. A spatial ability test and a scientific reasoning test were administered to both groups prior and after the study, which lasted for 9 weeks. The findings showed that there were significant statistical differences between the two groups in terms of spatial ability in favour of the experimental group. However, there were no differences between the two groups in terms of reasoning ability. The authors reasoned that the types of animations and simulations used in the current study featured a wide range of three-dimensional animated illustrations at the particulate level of matter. Most probably, this decreased the level of abstractness that usually accompanies chemical entities and phenomena and helped the students to visualize the interactions between submicroscopic entities spatially. Further research is needed to decide on types of scientific animations that could help students improve their scientific reasoning.

    2012-04-01

    Many findings from research as well as reports from teachers describe students' problem solving strategies as manipulation of formulas by rote. The resulting dissatisfaction with quantitative physical textbook problems seems to influence the attitude towards the role of mathematics in physics education in general. Mathematics is often seen as a tool for calculation which hinders a conceptual understanding of physical principles. However, the role of mathematics cannot be reduced to this technical aspect. Hence, instead of putting mathematics away we delve into the nature of physical science to reveal the strong conceptual relationship between mathematics and physics. Moreover, we suggest that, for both prospective teaching and further research, a focus on deeply exploring such interdependency can significantly improve the understanding of physics. To provide a suitable basis, we develop a new model which can be used for analysing different levels of mathematical reasoning within physics. It is also a guideline for shifting the attention from technical to structural mathematical skills while teaching physics. We demonstrate its applicability for analysing physical-mathematical reasoning processes with an example.

  2. Concept Maps for Improved Science Reasoning and Writing: Complexity Isn’t Everything

    2015-01-01

    A pervasive notion in the literature is that complex concept maps reflect greater knowledge and/or more expert-like thinking than less complex concept maps. We show that concept maps used to structure scientific writing and clarify scientific reasoning do not adhere to this notion. In an undergraduate course for thesis writers, students use concept maps instead of traditional outlines to define the boundaries and scope of their research and to construct an argument for the significance of their research. Students generate maps at the beginning of the semester, revise after peer review, and revise once more at the end of the semester. Although some students revised their maps to make them more complex, a significant proportion of students simplified their maps. We found no correlation between increased complexity and improved scientific reasoning and writing skills, suggesting that sometimes students simplify their understanding as they develop more expert-like thinking. These results suggest that concept maps, when used as an intervention, can meet the varying needs of a diverse population of student writers. PMID:26538388

    Developing a position on a socio-scientific issue and defending it using a well-reasoned justification involves complex cognitive skills that are challenging to both teach and assess. Our work centers on instructional strategies for fostering critical thinking skills in high school students using bioethical case studies, decision-making frameworks, and structured analysis tools to scaffold student argumentation. In this study, we examined the effects of our teacher professional development and curricular materials on the ability of high school students to analyze a bioethical case study and develop a strong position. We focused on student ability to identify an ethical question, consider stakeholders and their values, incorporate relevant scientific facts and content, address ethical principles, and consider the strengths and weaknesses of alternate solutions. 431 students and 12 teachers participated in a research study using teacher cohorts for comparison purposes. The first cohort received professional development and used the curriculum with their students; the second did not receive professional development until after their participation in the study and did not use the curriculum. In order to assess the acquisition of higher-order justification skills, students were asked to analyze a case study and develop a well-reasoned written position. We evaluated statements using a scoring rubric and found highly significant differences (p<0.001) between students exposed to the curriculum strategies and those who were not. Students also showed highly significant gains (p<0.001) in self-reported interest in science content, ability to analyze socio-scientific issues, awareness of ethical issues, ability to listen to and discuss viewpoints different from their own, and understanding of the relationship between science and society. Our results demonstrate that incorporating ethical dilemmas into the classroom is one strategy for increasing student motivation and

    Roth, Wolff-Michael; Milkent, Marlene M.

    This study was designed as a test for two neo-Piagetian theories. More specifically, this research examined the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories. A priori hypotheses linked the number of problems students worked until they induced a proportional reasoning strategy to the variables of M-space, degree of field dependence, and short-term storage space. The subjects consisted of students enrolled in Physical Science I, a science course for nonscience majors at the University of Southern Mississippi. Of the 34 subjects in the study, 23 were classified as concrete operational on the basis of eight ratio tasks. Problems corresponding to five developmental levels of proportional reasoning (according to Piagetian and neo-Piagetian theory), were presented by a microcomputer to the 23 subjects who had been classified as concrete operational. After a maximum of 6 hours of treatment, 17 of the 23 subjects had induced ratio schemata at the upper formal level (IIIB), while the remaining subjects used lower formal level (IIIA) schemata. The data analyses showed that neither M-space and degree of field-dependence, either alone or in combination, nor short-term storage predicted the number of problems students need to do until they induce an appropriate problem-solving strategy. However, there were significant differences in the short-term storage space of those subjects who mastered ratio problems at the highest level and those who did not. Also, the subjects' degree of field-dependence was not a predictor of either the ability to transfer problem-solving strategies to a new setting or the reuse of inappropriate strategies. The results of this study also suggest that short-term storage space is a variable with high correlations to a number of aspects of learning such as transfer and choice of strategy after feedback.

    Sampath Kumar, Bharath

    The purpose of this study is to examine the role of partnering visualization tool such as simulation towards development of student's concrete conceptual understanding of chemical equilibrium. Students find chemistry concepts abstract, especially at the microscopic level. Chemical equilibrium is one such topic. While research studies have explored effectiveness of low tech instructional strategies such as analogies, jigsaw, cooperative learning, and using modeling blocks, fewer studies have explored the use of visualization tool such as simulations in the context of dynamic chemical equilibrium. Research studies have identified key reasons behind misconceptions such as lack of systematic understanding of foundational chemistry concepts, failure to recognize the system is dynamic, solving numerical problems on chemical equilibrium in an algorithmic fashion, erroneous application Le Chatelier's principle (LCP) etc. Kress et al. (2001) suggested that external representation in the form of visualization is more than a tool for learning, because it enables learners to make meanings or express their ideas which cannot be readily done so through a verbal representation alone. Mixed method study design was used towards data collection. The qualitative portion of the study is aimed towards understanding the change in student's mental model before and after the intervention. A quantitative instrument was developed based on common areas of misconceptions identified by research studies. A pilot study was conducted prior to the actual study to obtain feedback from students on the quantitative instrument and the simulation. Participants for the pilot study were sampled from a single general chemistry class. Following the pilot study, the research study was conducted with a total of 27 students (N=15 in experimental group and N=12 in control group). Prior to participating in the study, students have completed their midterm test on the topic of chemical equilibrium. Qualitative

    Full Text Available In this paper we address the problem of student dropout from e-learning programmes. The proponents of e-learning highlight several advantages of this type of education as compared to the traditional, such as greater openness and diversity of training materials, the ability to adjust the mode and speed of learning, and similar. Despite these advantages, an increasing number of programmes and acceptance of e-learning as a national strategy all around the world, e-learning providers also face the problem of drop-outs. Research shows that student dropout in educational programmes implemented in the form of e-learning is higher than in traditional programmes. The reasons that affect the dropout rate should be considered when designing and implementing e-learning programmes

    2017-09-01

    This study had two purposes: (1) to develop university classes in which students can participate in intercultural dialogue by exchanging letters focusing on a topic about everyday norms implicit in each culture, and (2) to examine how students develop their intercultural understanding through participating in these classes. Twenty-two Japanese and six Chinese university students (each group in their own country) participated in three class sessions. At the beginning of the first class, students were given a dialogue theme that focused on cultural differences. The selected theme was mobile phone use while riding on public transportation, as this practice is prohibited in Tokyo but not in Beijing. Students discussed their opinions in small groups, wrote questions to their counterparts in the other country, and then reflected on and discussed the answers received. Analysis of the Japanese students' written reflections showed that their understanding of different cultural values and beliefs changed from one based only on a Japanese cultural perspective to one that respected the relativity of cultural norms. The results suggested that the arousal of negative emotions when students are exposed to the perspectives of other cultures is closely related to their understanding of cultural relativity.

    Shemesh, Michal

    The purpose of this study was to investigate gender-related differences in the relationship between the development of formal reasoning skills and learning interests during the early adolescent stage. For this purpose, 249 students, from seventh to ninth grade, were assessed for their level of mastery of formal reasoning skills by a test based on videotaped simple experiments. Learning interests were assessed by a written response to an open question. Results showed that adolescent boys develop patterns of formal reasoning before their girl classmates. In addition, boys tend to prefer science and technology subjects, while girls tend to prefer language, social studies, and humanities. Analysis of interactions showed that boys' tendency toward science and technology is positively correlated to their age and development of formal reasoning, while girls' tendency to the above subjects is positively related to their development of formal reasoning capacity, but inversely related to their age. Possible explanations to the above-described findings and suggestions for instructional modes that may increase girls' interest in science and technology are discussed.

  18. Controversy in the classroom: How eighth-grade and undergraduate students reason about tradeoffs of genetically modified food

    Seethaler, Sherry Lynn

    Current issues in science provide a rich context for learning because they can involve complex tradeoffs that cut across traditional disciplinary boundaries. Despite this potential benefit, and the need for citizens to make decisions about such issues, science controversy remains rare in the classroom. Consequently, there is much unknown about how students make sense of complex, multidisciplinary science. This research examined eighth-grade (n = 190) and undergraduate (n = 9) students' reasoning about tradeoffs in the genetically modified food controversy (main study). To extend the findings from the main study, undergraduate students' reasoning was followed as they learned about ten additional science controversies (extension). The studies took place in the context of curricula designed on the basis of the Scaffolded Knowledge Integration Framework, which posits a set of design principles that help students form a rich, integrated network of ideas about a topic. Two new methodologies were developed for this work. The Embedded Perspective of Science Controversy was used to study students' integration of content in their written arguments (main study) and oral and written questions (extension). The Perspective views science controversy as a set of nested levels, where tradeoffs are one of the levels, but connecting to other levels (underlying scientific details, bigger picture context, etc.) is important for the weighing of tradeoffs. A scheme based on Toulmin's (1958) work on argumentation provided a way of comparing the structure of students' arguments. As indicated by pre and post test scores, the curriculum helped both eighth-grade students (t = 11.7, p genetically modified food. In their final papers, both eighth-grade and undergraduate students presented evidence for and against their positions, in contrast with prior literature showing individuals have difficulty coming up with evidence against their positions. The students were also moving across the levels

    Researchers who have investigated the public understanding of science have argued that fictional cinema and television has proven to be particularly effective at blurring the distinction between fact and fiction. The rationale for this study lies in the notion that to teach science effectively, educators need to understand how popular culture influences their students' perception and understanding of science. Using naturalistic research methods in a diverse middle school we found that students who watched a popular science fiction film, The Core, had a number of misunderstandings of earth science concepts when compared to students who did not watch the movie. We found that a single viewing of a science fiction film can negatively impact student ideas regarding scientific phenomena. Specifically, we found that the film leveraged the scientific authority of the main character, coupled with scientifically correct explanations of some basic earth science, to create a series of plausible, albeit unscientific, ideas that made sense to students.

  20. REASONS FOR STUDENT DISCONTINUATION IN ENGINEERING DEGREE COURSES OFFERED AT A DISTANCE

    Directory of Open Access Journals (Sweden)

    Full Text Available Faculty of Engineering Technology of the Open University of Sri Lanka has been offering engineering programmes at a distance for the last two decades or so. However, completion rates in Faculty of Engineering Technology are lower compared to the other faculties of the University. This paper investigates the reasons for low completion rates in the faculty and suggests ways and means to overcome this problem. The study concludes that increasing student numbers will not necessarily increase percentage of students completing the programme though the number of students completing is increased. It is found that students offering courses for the first time in the system of distance education in their academic career perform poorer because they are not conversant with distance education techniques. It is recommended that the Faculty must offer an orientation programme on distance education to all the students enrolling for the first time, before they commence their regular programmes. Further, it has been found that considerable percentage of students who obtain eligibility to sit the final examination by completing the continuous assessments do not sit the final examination. This has been found to contribute towards non-completion of programmes as students sitting the final examination in the subsequent years perform poorly in their exams. To overcome this problem, it is recommended that current practise of allowing the student to carry forward their eligibility to unlimited period of time must be disbanded.

  1. Reasons and motivations for the option of an engineering career in Portugal

    2011-08-01

    Towards the end of their secondary education, students face significant pressures in their decision about their career plan. These pressures are internal and external, personal and social, individual and from the reference group. This paper aims at understanding the reasons driving engineering students' choices, their perceived needs and aspirations. Moreover, it discusses how, in that process, students are constrained by family and friends and are conditioned by factors such as their socioeconomic and cultural background, employability prospects and gender. The construction of a career map/plan and the reasons and motivations for the option of an engineering career are reviewed, based on the qualitative analysis of students' discourses. The data indicate the relevance of several criteria such as social status, intelligence, gender, competences, values and interests in the construction of career aspirations. All these levels are highly influenced by self-esteem, which is closely related to the social value of training options and career paths.

    A primary objective of health care reform is to provide affordable and quality health insurance to individuals. Currently, promotional efforts have been moderately successful in registering older, more mature adults yet comparatively less successful in registering younger adults. With this challenge in mind, we conducted extensive formative research to better understand the attitudes, subjective norms, and perceived behavioral control of community college students. More specifically, we examined how each relates to their intentions to enroll in a health insurance plan, maintain their current health insurance plan, and talk with their parents about their parents having health insurance. In doing so, we relied on the revised reasoned action approach advanced by Fishbein and his associates (Fishbein & Ajzen, 2010; Yzer, 2012, 2013). Results showed that the constructs predicted intentions to enroll in health insurance for those with no insurance and for those with government-sponsored insurance and intentions to maintain insurance for those currently insured. Our study demonstrates the applicability of the revised reasoned action framework within this context and is discussed with an emphasis on the practical and theoretical contributions.

    1997-01-01

    Two studies examined the relationships between anxiety sensitivity (AS), drug use, and reasons for drug use. In Study 1, 229 university students (57% F) completed the Anxiety Sensitivity Index (ASI) and a drug use survey, assessing use of a variety of drugs within the last month, and coping reasons for drug use. Consistent with a modified tension-reduction hypothesis, ASI scores were positively correlated with the number of both anxiety- and depression-related reasons for drug use endorsed. In Study 2, 219 university students (74% F) completed the ASI and a drug use survey, assessing use of several drugs (e.g., alcohol, cigarettes, caffeine, and marijuana/hashish) within the last year, and primary reasons (coping, affiliative, or enhancement) for the use of each drug. Marijuana/hashish users reported lower ASI scores than non-users supporting a negative relation between AS and the use of cannabis. ASI scores were positively correlated with the use of alcohol primarily to cope, and negatively correlated with the use of alcohol primarily to affiliate, among both gender groups, and ASI scores were positively correlated with the use of nicotine primarily to cope among the females. Implications of these findings for understanding risk for abuse of stress-response-dampening drugs by high AS individuals are discussed.

    This paper describes the conceptual design and testing of an Interactive Computerised Decision Support Framework (ICDSF) which was constructed to enable student nurses to "think like a nurse." The ICDSF was based on a model of clinical reasoning. Teaching student nurses to reason clinically is important as poor clinical reasoning skills can lead to "failure-to rescue" of deteriorating patients. The framework of the ICDSF was based on nursing concepts to encourage deep learning and transferability of knowledge. The principles of active student participation, situated cognition to solve problems, authenticity, and cognitive rehearsal were used to develop the ICDSF. The ICDSF was designed in such a way that students moved through it in a step-wise fashion and were required to achieve competency at each step before proceeding to the next. The quality of the ICDSF was evaluated using a questionairre survey, students' written comments and student assessment measures on a pilot and the ICDSF. Overall students were highly satisfied with the clinical scenarios of the ICDSF and believed they were an interesting and useful way to engage in authentic clinical learning. They also believed the ICDSF was useful in developing cognitive skills such as clinical reasoning, problem-solving and decision-making. Some reported issues were the need for good technical support and the lack of face to face contact when using e-learning. Some students also believed the ICDSF was less useful than actual clinical placements. Copyright © 2010 Elsevier Ltd. All rights reserved.

  8. Withholding answers during hands-on scientific investigations? Comparing effects on developing students' scientific knowledge, reasoning, and application

    As more concerns have been raised about withholding answers during science teaching, this article argues for a need to detach 'withholding answers' from 'hands-on' investigation tasks. The present study examined students' learning of light-related content through three conditions: 'hands-on' + no 'withholding' (hands-on only: HO), 'hands-on' + 'withholding' (hands-on investigation with answers withheld: HOW), and no 'hands-on' + no 'withholding' (direction instruction: DI). Students were assessed in terms of how well they (1) knew the content taught in class; (2) reasoned with the learned content; and (3) applied the learned content to real-life situations. Nine classes of students at 4th and 5th grades, N = 136 in total, were randomly assigned to one of the three conditions. ANCOVA results showed that students in the hands-on only condition reasoned significantly better than those in the other two conditions. Students in this condition also seemed to know the content fairly better although the advance was not significant. Students in all three conditions did not show a statistically significant difference in their ability to apply the learned content to real-life situations. The findings from this study provide important contributions regarding issues relating to withholding answers during guided scientific inquiry.

    Many research shown that students have difficulty in understanding the concepts of integral calculus. Therefore this research is interested in designing a classroom activity integrated with design research method to assist students in understanding the integrals concept especially in calculating the volume of rotary objects using disc method. In order to support student development in understanding integral concepts, this research tries to use realistic mathematical approach by integrating geogebra software. First year university student who takes a calculus course (approximately 30 people) was chosen to implement the classroom activity that has been designed. The results of retrospective analysis show that visualizing volume of rotary objects using geogebra software can assist the student in understanding the disc method as one way of calculating the volume of a rotary object.

    2017-01-01

    In the last decade, more and more medicine students are involved in research, either in the form of a research project within specialized courses or as a scientific article to be presented at student international conferences or published in prestigious medical journals. The present study included 250 2nd year medical students, currently studying within the University of Medicine and Pharmacy of Craiova, Romania. There were collected 239 responses, with a response rate of 95.6%. In our study, the results showed that foreign students within the University of Medicine and Pharmacy of Craiova did have some issues understanding plagiarism with fewer foreign students (34%) than Romanian students (66%) recognizing that simply changing words does not avoid plagiarism. In our opinion, there should be put more emphasis upon plagiarism implications and its aspects, as well, with a permanent order to try to prevent future attempts of plagiarizing among medical students as future researchers within the medical science field.

  11. Probing student understanding of scientific thinking in the context of introductory astrophysics

    Directory of Open Access Journals (Sweden)

    Richard N. Steinberg

    2009-09-01

    Full Text Available Common forms of testing of student understanding of science content can be misleading about their understanding of the nature of scientific thinking. Observational astronomy integrated with related ideas of force and motion is a rich context to explore the correlation between student content knowledge and student understanding of the scientific thinking about that content. In this paper, we describe this correlation in detail with a focus on a question about the relative motion of the Sun and the Earth. We find that high achieving high school students throughout New York City struggle with what constitutes scientific justification and thought processes, but can improve these skills tremendously in an inquiry-oriented summer astronomy-physics program.

    2017-07-01

    Full Text Available Russians and Westerners access, process and communicate information in different ways. Whilst Westerners favour detailed analysis of subject matter, Russians tend to focus on certain components that are, in their view, significant. This disparity makes it difficult to achieve constructive dialogues between Western and Russian stakeholders contributing to cross-cultural communication problems. The author claims that the difference in the ways Russians and Westerners negotiate information is a significant cultural difference between Russia and West rather than an irritating (and in principle amenable lack of analytical skills on the Russian partners’ part. Understanding the reasons behind the Russian-specific approaches to dealing with information would be a positive step towards a more effective cross-cultural communication, important in business situations and essential in diplomacy.

    Full Text Available The aim of this cross-sectional study was to determine, among medical students at a public university in Rio de Janeiro, Brazil, the acceptance of the pandemic influenza A/H1N1 vaccine during the 2010 mass immunization campaign and the vaccine safety in this group and, among unvaccinated students, the reasons for refusing vaccination. Of a total of 858 students, 678 (79% participated in the study. Vaccination coverage was 60.4% among students aged 20 to 39 years (an age group targeted for vaccination and 43.8% among those who did not belong to this age group. The most frequent adverse reactions to the vaccine were pain at the injection site (8.7% and fever (7.9%. There were no serious adverse reactions. Among students aged 20 to 39 years, the most common reasons for refusing the vaccine were "lack of time" (42.4%, "fear of adverse reactions" (41.9%, and "difficult access to the vaccine" (11.5%. Other reasons for vaccine refusal were "uncertainties about vaccine safety and efficacy" and "vaccination was not needed". To increase the acceptance of the influenza vaccine, a comprehensive immunization program should be offered to these students.

    2017-08-01

    Full Text Available Informal reasoning is the basic reasoning frequently used by most people to solve complex daily life problems. Unlike scientific reasoning, informal reasoning includes cognitive and affective processes that the types of reasoning can be intuitive, emotive and rational. This cross sectional study describes the development of students’ informal reasoning at elementary school, junior high school, and senior high school. Moreover, the study also identifies differences between boys and girls reasoning. Participants are 20 elementary school students, 30 junior high school students, and 30 high school students who attend schools managed by the same foundation. Data were collected using five items test on issues found in everyday life. Students’ responses were grouped into intuitive, emotive, or rational reasoning. The results suggest that students’ informal reasoning tend to develop parallel to the school grade. Related to gender, the study finds that girls tend to use rational reasoning while boys tend to use intuitive reasoning.

  18. Examing nursing students' understanding of the cardiovascular system in a BSN program

    Science.gov (United States)

    Stuart, Parker Emerson

    This study investigated the alignment of important cardiovascular system (CVS) concepts identified by expert nurses with nursing student's knowledge. Specifically, it focused on the prevalence of nursing students' alternative conceptions for these important concepts as a potential reason for a theory-practice gap in nursing (Corlett, 2000; Jordan, 1994). This is the first study to target nursing student alternative conceptions exclusively whereas other studies focused on diverse groups of undergraduates' CVS knowledge (Michael et al., 2002). The study was divided into two phases and used a case study approach with each phase of the study representing a single case. The first phase of the study sought to understand what CVS concepts expert nurses deemed relevant to their daily practice and how these experts used these concepts. The second phase identified nursing student alternative conceptions through the use of open-ended scenarios based on the results of phase I. For the first phase of the study involved four CVS expert nurses practicing in emergency rooms and cardiac intensive care units at two local hospitals. Interviews were used to elicit important CVS concepts. The expert nurses identified five broad concepts as important to their practice. These concepts were a) cardiovascular anatomical concepts; b) cardiovascular physiological concepts; c) homeostasis and diseases of the CVS; d) the interdependence and interaction of the CVS with other organ systems and e) the intersection of the CVS and technology in patient diagnosis and treatment. These finding reinforce concepts already being taught to nursing students but also suggest that instruction should focus more on how the CVS interacts with other organ systems and how technology and the CVS interact. The presence of alternative conceptions in the nursing students was examined through the use of open-ended questions. A total of 17 students fully completed the scenario questions. Results indicate that this

    2018-01-01

    The paper examined Thai student existing understanding about the solar system model and the motion of the stars. The participants included 141 Grade 9 students in four different schools of the Surin province, Thailand. Methodology regarded interpretive paradigm. The tool of interpretation included the Student Celestial Motion Conception Questionnaire (SCMCQ) and informal interview. Given understandings in the SCMCQ were read through and categorized according to students' understandings. Then, students were further probed as informal interview. Students' understandings in each category were counted and percentages computed. Finally, students' understandings across four different schools were compared and contrasted using the percentage of student responses in each category. The findings revealed that most students understand about Sun-Moon-Earth (SME) system and solar system model as well, they can use scientific explanations to explain the celestial objects in solar system and how they orbiting. Unfortunately, most of students (more than 70%) never know about the Polaris, the North Star, and 90.1% of them never know about the ecliptic, and probably also the 12 zodiac constellations. These existing understanding suggested some ideas of teaching and learning about solar system model and the motion of the stars. The paper, then, discussed some learning activities to enhance students to further construct meaning about solar system model and the motion of the stars.

    The authors conducted a survey of university students' understanding level about words related to nuclear power before and after Fukushima Daiichi Power Plant accident, and analyzed the difference between before and after the accident. The results show that university students' understanding level improved after the accident, especially in the case of reported words by mass media. Understanding level of some nuclear power security words which were not reported so much by mass media also improved. That may be caused by rising of people's concern about nuclear power generation after the accident, and there is a possibility that the accident motivated people to access such words via internet, journals, etc. (author)

  3. Assessing Students' Understanding of Macroevolution: Concerns regarding the validity of the MUM

    Science.gov (United States)

    Novick, Laura R.; Catley, Kefyn M.

    2012-11-01

    In a recent article, Nadelson and Southerland (2010. Development and preliminary evaluation of the Measure of Understanding of Macroevolution: Introducing the MUM. The Journal of Experimental Education, 78, 151-190) reported on their development of a multiple-choice concept inventory intended to assess college students' understanding of macroevolutionary concepts, the Measure of Understanding Macroevolution (MUM). Given that the only existing evolution inventories assess understanding of natural selection, a microevolutionary concept, a valid assessment of students' understanding of macroevolution would be a welcome and necessary addition to the field of science education. Although the conceptual framework underlying Nadelson and Southerland's test is promising, we believe the test has serious shortcomings with respect to validity evidence for the construct being tested. We argue and provide evidence that these problems are serious enough that the MUM should not be used in its current form to measure students' understanding of macroevolution.

    2017-01-02

    Since the early 1990s, the United States has seen a significant increase in the prevalence of prescription opioid misuse. Despite benefits prescription opioids provide, misuse can be fatal. The current study was designed to investigate the prevalence of prescription opioid misuse, perceived harm of misuse, and reasons for misuse for physical or emotional pain instead of seeking professional medical or mental health treatment. Survey data were collected in the fall of 2013 via an online survey to a random sample of 668 students from a public Midwestern university. Lifetime prevalence of prescription opioid misuse was 9.5%. Misusers of prescription opioid drugs generally reported lower ratings of perceived harm as compared to individuals not reporting misuse of prescription opioid drugs. Primary reasons for misuse of prescription opioid drugs was to relieve pain (33.9%), "to feel good/get high" (23.2%) and experimentation (21.4%). Lifetime misuse of a prescription opioid drug for physical or emotional pain was reported by 8.1% and 2.2% of respondents, respectively. Primary reasons for misuse for physical pain included because pain was temporary, immediate relief was needed, and no health insurance/financial resources. Primary reasons for misuse for emotional pain included not wanting others to find out, embarrassment and fear. Conclusions/Importance: Reasons for misuse of prescription opioid drugs vary by type of prescription opioid drug. Reasons for not seeking treatment that ultimately lead to misuse, vary by type of pain being treated and may be important considerations in the effort to stem the misuse of prescription opioid drugs among college students.

  5. Scaffolding software: How does it influence student conceptual understanding and motivation?

    Science.gov (United States)

    Butler, Kyle A.

    The purpose of this study was to determine the influence of scaffolding software on student conceptual understanding and motivation. This study also provides insight on how students use the scaffolding features found in Artemis and the extent to which features show a relationship to student conceptual understanding and motivation. A Randomized Solomon Four Group Design was used in this study. As students worked through a project based unit over photosynthesis, the students performed information seeking activities that were based on their own inquiry. For this purpose, the students in the experimental group used an example of scaffolding software called Artemis, while the students in the control group used a search engine of their choice. To measure conceptual understanding, the researcher analyzed student generated concept maps on photosynthesis using three different methods (quantitative, qualitative, hierarchical). To measure motivation, the researcher used a survey that measured motivation on five different indicators: intrinsic goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy for learning and performance. Finally, the researcher looked at the relationship and influence of the scaffolding features on two student performance scores at the end of the unit. This created a total of ten dependent variables in relationship to the treatment. Overall, the students used the collaborative features 25% of the time, the maintenance features 0.84% of the time, the organizational features 16% of the time, the saving/viewing features 7% of the time and the searching features 51% of the time. There were significant correlations between the saving/viewing features hits and the students' task value (r = .499, p motivation.

All student teachers, who were accepted to the programme one year, were followed trough 2.5 years of the programme. The student teachers took science courses in which they were taught about the greenhouse effect.Data was collected by questionnaires three times. The results show that a majority of the student teachers developed an adequate understanding of the greenhouse effect during the teaching programme. Several of the students developed further in the second science course. However a rather big group of students with poor understanding did not develop any further in the second science course and no one demonstrated full understanding. Different ways of collecting data and categorising responses affected how the students’ understanding was interpreted.

    This study aims to analyse university students' reasoning regarding two laws of electromagnetism: Gauss's law and Ampere's law. It has been supposed that the problems seen in understanding and applying both laws do not spring from students' misconceptions. Students habitually use reasoning known in the literature as 'common sense' methodology that leads to incorrect forms of reasoning. To test our hypothesis, questionnaires were designed emphasizing explanations. The results obtained show the low level of students' reasoning in both electricity and magnetism in terms of Gauss's and Ampere's laws

    According to national mathematics standards, algebra instruction should begin at kindergarten and continue through elementary school. Most often, teachers address algebra in the elementary grades with problems related to solving equations or understanding functions. With 789 2nd- grade students, we administered (a) measures of calculations and word problems in the fall and (b) an assessment of pre-algebraic reasoning, with items that assessed solving equations and functions, in the spring. Based on the calculation and word-problem measures, we placed 148 students into 1 of 4 difficulty status categories: typically performing, calculation difficulty, word-problem difficulty, or difficulty with calculations and word problems. Analyses of variance were conducted on the 148 students; path analytic mediation analyses were conducted on the larger sample of 789 students. Across analyses, results corroborated the finding that word-problem difficulty is more strongly associated with difficulty with pre-algebraic reasoning. As an indicator of later algebra difficulty, word-problem difficulty may be a more useful predictor than calculation difficulty, and students with word-problem difficulty may require a different level of algebraic reasoning intervention than students with calculation difficulty.

  14. How People Reason: A Grounded Theory Study of Scientific Reasoning about Global Climate Change

    Liu, Shiyu

    Scientific reasoning is crucial in both scientific inquiry and everyday life. While the majority of researchers have studied "how people reason" by focusing on their cognitive processes, factors related to the underpinnings of scientific reasoning are still under-researched. The present study aimed to develop a grounded theory that captures not only the cognitive processes during reasoning but also their underpinnings. In particular, the grounded theory and phenomenographic methodologies were integrated to explore how undergraduate students reason about competing theories and evidence on global climate change. Twenty-six undergraduate students were recruited through theoretical sampling. Constant comparative analysis of responses from interviews and written assessments revealed that participants were mostly drawn to the surface features when reasoning about evidence. While prior knowledge might not directly contribute to participants' performance on evidence evaluation, it affected their level of engagement when reading and evaluating competing arguments on climate issues. More importantly, even though all participants acknowledged the relative correctness of multiple perspectives, they predominantly favored arguments that supported their own beliefs with weak scientific reasoning about the opposing arguments. Additionally, factors such as personal interests, religious beliefs, and reading capacity were also found to have bearings on the way participants evaluated evidence and arguments. In all, this work contributes to the current endeavors in exploring the nature of scientific reasoning. Taking a holistic perspective, it provides an in-depth discussion of factors that may affect or relate to scientific reasoning processes. Furthermore, in comparison with traditional methods used in the literature, the methodological approach employed in this work brought an innovative insight into the investigation of scientific reasoning. Last but not least, this research may

    2008-10-01

    This study was designed to theoretically articulate and empirically assess the role of computer scaffolds. In this project, several examples of educational software were developed to scaffold the learning of students performing high level cognitive activities. The software used in this study, Artemis, focused on scaffolding the learning of students as they performed information seeking activities. As 5th grade students traveled through a project-based science unit on photosynthesis, researchers used a pre-post design to test for both student motivation and student conceptual understanding of photosynthesis. To measure both variables, a motivation survey and three methods of concept map analysis were used. The student use of the scaffolding features was determined using a database that tracked students' movement between scaffolding tools. The gain scores of each dependent variable was then correlated to the students' feature use (time and hits) embedded in the Artemis Interface. This provided the researchers with significant relationships between the scaffolding features represented in the software and student motivation and conceptual understanding of photosynthesis. There were a total of three significant correlations in comparing the scaffolding use by hits (clicked on) with the dependent variables and only one significant correlation when comparing the scaffold use in time. The first significant correlation ( r = .499, p students' task value. This correlation supports the assumption that there is a positive relationship between the student use of the saving/viewing features and the students' perception of how interesting, how important, and how useful the task is. The second significant correlation ( r = 0.553, p students' self-efficacy for learning and performance. This correlation supports the assumption that there is a positive relationship between the student use of the searching features and the students' perception of their ability to accomplish a task as

    2014-01-01

    Over the last 20 years, science education studies have reported that there are very different understandings among students of science regarding the key aspects of climate change. We used the cognitive linguistic framework of experientialism to shed new light on this valuable pool of studies to identify the conceptual resources of understanding climate change. In our study, we interviewed 35 secondary school students on their understanding of the greenhouse effect and analysed the conceptions of climate scientists as drawn from textbooks and research reports. We analysed all data by metaphor analysis and qualitative content analysis to gain insight into students' and scientists' resources for understanding. In our analysis, we found that students and scientists refer to the same schemata to understand the greenhouse effect. We categorised their conceptions into three different principles the conceptions are based on: warming by more input, warming by less output, and warming by a new equilibrium. By interrelating students' and scientists' conceptions, we identified the students' learning demand: First, our students were afforded with experiences regarding the interactions of electromagnetic radiation and CO2. Second, our students reflected about the experience-based schemata they use as source domains for metaphorical understanding of the greenhouse effect. By uncovering the-mostly unconscious-deployed schemata, we gave students access to their source domains. We implemented these teaching guidelines in interventions and evaluated them in teaching experiments to develop evidence-based and theory-guided learning activities on the greenhouse effect.

    This study evaluated the short- and long-term effectiveness of faculty training to enhance clinical evaluation of ethical reasoning and professionalism in a baccalaureate dental hygiene program. Ethics, values, and professionalism are best measured in contexts comparable to practice; therefore, authentic evaluation is desirable for assessing these areas of competence. Methods were the following: 1) a faculty development workshop implementing a core values-based clinical evaluation system for assessing students' professional judgment; 2) subsequent evaluation of the clinical faculty's use of core values for grading and providing written comments related to students' professional judgment during patient care for three academic years; and 3) evaluation of program outcomes assessments regarding clinical learning experiences related to ethics and professionalism domains. Results revealed the clinical faculty's evaluation of professional judgment during patient care was enhanced by training; written comments more frequently related to core values defined in the American Dental Hygienists' Association (ADHA) Code of Ethics; and faculty members reported more confidence and comfort evaluating professional judgment after implementation of this evaluation system and receiving training in its application. Students were more positive in outcomes assessments about their competency and learning experiences related to professionalism and ethics. This article shares one approach for enhancing clinical faculty's authentic evaluation of student competence in ethical reasoning and professionalism.

  20. The pursuit of understanding: A study of exemplary high school students' conceptions of knowledge validation in science and history

    Boix Mansilla, Veronica Maria

    The study presented examined 16 award-winning high school students' beliefs about the criteria by which scientific theories and historical narratives are deemed trustworthy. It sought to (a) describe such beliefs as students reasoned within each discipline; (b) examine the degree to which such beliefs were organized as coherent systems of thought; and (c) explore the relationship between students' beliefs and their prior disciplinary research experience. Students were multiple-year award-winners at the Massachusetts Science Fair and the National History Day---two pre-collegiate State-level competitions. Two consecutive semi-structured interviews invited students to assess and enhance the trustworthiness of competing accounts of genetic inheritance and the Holocaust in science and history respectively. A combined qualitative and quantitative data analysis yielded the following results: (a) Students valued three standards of acceptability that were common across disciplines: e.g. empirical strength, explanatory power and formal and presentational strength. However, when reasoning within each discipline they tended to define each standard in disciplinary-specific ways. Students also valued standards of acceptability that were not shared across disciplines: i.e., external validity in science and human understanding in history. (b) In science, three distinct epistemological orientations were identified---i.e., "faith in method," "trusting the scientific community" and "working against error." In history students held two distinct epistemologies---i.e., "reproducing the past" and "organizing the past". Students' epistemological orientations tended to operate as collections of mutually supporting ideas about what renders a theory or a narrative acceptable. (c) Contrary to the standard position to date in the literature on epistemological beliefs, results revealed that students' research training in a particular discipline (e.g., science or history) was strongly related to

    Climate change is one of the most significant science issues facing humanity; yet, teaching students about climate change is challenging: not only is it multidisciplinary, but also it is contentious and debated in political, social and media forums. Students need to be equipped with an understanding of climate change science to be able to participate in this discourse. The purpose of this study was to examine Western Australian high school students' understanding of climate change and the greenhouse effect, in order to identify their alternative conceptions about climate change science and provide a baseline for more effective teaching. A questionnaire designed to elicit students' understanding and alternative conceptions was completed by 438 Year 10 students (14-15 years old). A further 20 students were interviewed. Results showed that students know different features of both climate change and the greenhouse effect, however not necessarily all of them and the relationships between. Five categories of alternative conceptions were identified. The categories were (1) the greenhouse effect and the ozone layer; (2) types of greenhouse gases; (3) types of radiation; (4) weather and climate and (5) air pollution. These findings provide science educators a basis upon which to develop strategies and curriculum resources to improve their students' understanding and decision-making skills about the socioscientific issue, climate change.

    Identifying students' difficulties in learning concept of probability is important for teachers to prepare the appropriate learning processes and can overcome obstacles that may arise in the next learning processes. This study revealed the level of students' understanding of the concept of probability and identified their difficulties as a part of the epistemological obstacles identification of the concept of probability. This study employed a qualitative approach that tends to be the character of descriptive research involving 55 students of class XII. In this case, the writer used the diagnostic test of probability concept learning difficulty, observation, and interview as the techniques to collect the data needed. The data was used to determine levels of understanding and the learning difficulties experienced by the students. From the result of students' test result and learning observation, it was found that the mean cognitive level was at level 2. The findings indicated that students had appropriate quantitative information of probability concept but it might be incomplete or incorrectly used. The difficulties found are the ones in arranging sample space, events, and mathematical models related to probability problems. Besides, students had difficulties in understanding the principles of events and prerequisite concept.

    2017-01-01

    This study explores how interprofessional simulation-based education (IPSE) can contribute to a change in students' understanding of teamwork and professional roles. A series of 1-day training sessions was arranged involving undergraduate nursing and medical students. Scenarios were designed for practicing teamwork principles and interprofessional communication skills by endorsing active participation by all team members. Four focus groups occurred 2-4 weeks after the training. Thematic analysis of the transcribed focus groups was applied, guided by questions on what changes in students' understanding of teamwork and professional roles were identified and how such changes had been achieved. The first question, aiming to identify changes in students' understanding of teamwork, resulted in three categories: realizing and embracing teamwork fundamentals, reconsidering professional roles, and achieving increased confidence. The second question, regarding how participation in IPSE could support the transformation of students' understanding of teamwork and of professional roles, embraced another three categories: feeling confident in the learning environment, embodying experiences, and obtaining an outside perspective. This study showed the potential of IPSE to transform students' understanding of others' professional roles and responsibilities. Students displayed extensive knowledge on fundamental teamwork principles and what these meant in the midst of participating in the scenarios. A critical prerequisite for the development of these new insights was to feel confident in the learning environment. The significance of how the environment was set up calls for further research on the design of IPSE in influencing role understanding and communicative skills in significant ways.

    The application of information and communications technology (ICT) had become more important in our daily life, especially in educational field. Teachers are encouraged to use information system-based in teaching Mathematical courses. Higher Order Thinking Skills (HOTS) approach is unable to explain using chalk and talk methods. It needs students to analyze, evaluate, and create by their own natural abilities. The aim of this research study was to evaluate the effectiveness of the application information system-based in enhance the students understanding about HOTS question. Mixed-methods or quantitative and qualitative approach was applied in collecting data, which involve only the standard five students and the teachers in Sabak Bernam, Selangor. Pra-postests was held before and after using information system-based in teaching to evaluate the students' understanding. The result from post-test indicates significant improvement which proves that the use of information system based able to enhance students' understanding about HOTS question and solve it. There were several factor influenced the students such as students' attitude, teachers attraction, school facilities, and computer approach. Teachers play an important role in attracting students to learn. Therefore, the school should provide a conducive learning environment and good facilities for students to learn so that they are able to access more information and always exposed to new knowledge. As conclusion, information system-based are able to enhance students understanding the need of HOTS questions and solve it.

    While the gender gap in physics participation is a known problem, practical strategies that may improve the situation are not well understood. As physics education researchers, we draw on evidence to help inform us of what may or may not be working. To this end, physics identity has proven to be a useful framework for understanding and predicting participation in physics. Drawing on data from national surveys of college students, case studies in physics classes, and surveys of undergraduate women in physics, we identify strategies that are predictive of female students' physics identity development from their high school and undergraduate physics experiences. These findings will be discussed as well as future directions for using this research to increase the recruitment of women to physics-related careers. NSF Grant # 1431846.

  17. Does an Emphasis on the Concept of Quantum States Enhance Students' Understanding of Quantum Mechanics?

    Science.gov (United States)

    Greca, Ileana Maria; Freire, Olival

    Teaching physics implies making choices. In the case of teaching quantum physics, besides an educational choice - the didactic strategy - another choice must be made, an epistemological one, concerning the interpretation of quantum theory itself. These two choices are closely connected. We have chosen a didactic strategy that privileges the phenomenological-conceptual approach, with emphasis upon quantum features of the systems, instead of searching for classical analogies. This choice has led us to present quantum theory associated with an orthodox, yet realistic, interpretation of the concept of quantum state, considered as the key concept of quantum theory, representing the physical reality of a system, independent of measurement processes. The results of the mplementation of this strategy, with three groups of engineering students, showed that more than a half of them attained a reasonable understanding of the basics of quantum mechanics (QM) for this level. In addition, a high degree of satisfaction was attained with the classes as 80% of the students of the experimental groups claimed to have liked it and to be interested in learning more about QM.

  18. Middle school students' understanding of time: Implications for the National Science Education Standards

    Science.gov (United States)

    Reinemann, Deborah Jean

    2000-10-01

    Measures of time are essential to human life, especially in the Western world. Human understanding of time develops from the preschool stages of using "before" and "after" to an adult understanding and appreciation of time. Previous researchers (for example, Piaget, Friedman) have investigated and described stages of time development. Time, as it was investigated here, can be classified as conventional, logical or experiential. Conventional time is the ordered representation of time; the days of the week, the months of the year, or clock time: seconds and hours. Logical time is the deduction of duration based on regular events; for example, calculating the passage of time based on two separate events. Experiential time involves the duration of events and estimating intervals. With the recent production of the National Science Education Standards (NSES), many schools are aligning their science curriculum with the NSES. Time appears both implicitly and explicitly in the NSES. Do Middle School students possess the understanding of time necessary to meet the recommendations of the NSES? An interview protocol of four sessions was developed to investigate middle school students understanding of time. The four sessions included: building and testing water clocks; an interview about water clocks and time intervals; a laserdisc presentation about relative time spans; and a mind mapping session. Students were also given the GALT test of Logical Thinking. The subjects of the study were interviewed; eleven eighth grade students and thirteen sixth grade students. The data was transcribed and coded, and a rubric was developed to evaluate students based on their responses to the four sessions. The Time Analysis Rubric is a grid of the types of time: conventional, logical and experiential time versus the degree of understanding of time. Student results were assigned to levels of understanding based on the Time Analysis Rubric. There was a relationship (although not significant

  1. Evolving social responsibility understandings, motivations, and career goals of undergraduate students initially pursuing engineering degrees

    Science.gov (United States)

    Rulifson, Gregory A.

    Engineers impact the lives of every person every day, and need to have a strong sense of social responsibility. Understanding what students think about social responsibility in engineering and their futures is very important. Further, by identifying influences that change these ideas and shape their conceptualizations, we can intervene to help prepare students for their responsibilities as part of the profession in the future. This thesis presents the experiences, in their own words, of 34 students who started in engineering. The study is composed of three parts: (i) engineering students' ideas about socially responsible engineering and what influenced these ideas, (ii) how students see themselves as future socially responsible engineers and how this idea changes over their first three years of college, and (iii) what social responsibility-related reasons students who leave engineering have for choosing a new major. Results show that students are complicated and have varied paths through and out of engineering studies. Students came up with their own ideas about socially responsible engineering that converged over the years on legal and safety related aspects of the profession. Relatedly, students identified with the engineering profession through internships and engineering courses, and rarely described socially responsible aspirations that could be accomplished with engineering. More often, those students who desired to help the disadvantaged through their engineering work left engineering. Their choice to leave was a combination of an unsupportive climate, disinterest in their classes, and a desire to combine their personal and professional social responsibility ambitions. If we want engineering students to push the engineering profession forward to be more socially responsible, we can identify the effective influences and develop a curriculum that encourages critical thinking about the social context and impacts of engineering. Additionally, a social

    Full Text Available Abstract Background Virtual Patients (VPs are web-based representations of realistic clinical cases. They are proposed as being an optimal method for teaching clinical reasoning skills. International standards exist which define precisely what constitutes a VP. There are multiple design possibilities for VPs, however there is little formal evidence to support individual design features. The purpose of this trial is to explore the effect of two different potentially important design features on clinical reasoning skills and the student experience. These are the branching case pathways (present or absent and structured clinical reasoning feedback (present or absent. Methods/Design This is a multi-centre randomised 2x2 factorial design study evaluating two independent variables of VP design, branching (present or absent, and structured clinical reasoning feedback (present or absent.The study will be carried out in medical student volunteers in one year group from three university medical schools in the United Kingdom, Warwick, Keele and Birmingham. There are four core musculoskeletal topics. Each case can be designed in four different ways, equating to 16 VPs required for the research. Students will be randomised to four groups, completing the four VP topics in the same order, but with each group exposed to a different VP design sequentially. All students will be exposed to the four designs. Primary outcomes are performance for each case design in a standardized fifteen item clinical reasoning assessment, integrated into each VP, which is identical for each topic. Additionally a 15-item self-reported evaluation is completed for each VP, based on a widely used EViP tool. Student patterns of use of the VPs will be recorded. In one centre, formative clinical and examination performance will be recorded, along with a self reported pre and post-intervention reasoning score, the DTI. Our power calculations indicate a sample size of 112 is required for

    Moral Case Deliberation is one form of clinical ethics support described as a facilitator-led collective moral reasoning by healthcare professionals on a concrete moral question connected to their practice. Evaluation research is needed, but, as human interaction is difficult to standardise, there is a need to capture the content beyond moral reasoning. This allows for a better understanding of Moral Case Deliberation, which may contribute to further development of valid outcome criteria and stimulate the normative discussion of what Moral Case Deliberation should contain. To explore and compare the content beyond moral reasoning in the dialogue in Moral Case Deliberation at Swedish workplaces. A mixed-methods approach was applied for analysing audio-recordings of 70 periodic Moral Case Deliberation meetings at 10 Swedish workplaces. Moral Case Deliberation facilitators and various healthcare professions participated, with registered nurses comprising the majority. Ethical considerations: No objection to the study was made by an Ethical Review Board. After oral and written information was provided, consent to be recorded was assumed by virtue of participation. Other than 'moral reasoning' (median (md): 45% of the spoken time), the Moral Case Deliberations consisted of 'reflections on the psychosocial work environment' to a varying extent (md: 29%). Additional content comprised 'assumptions about the patient's psychosocial situation' (md: 6%), 'facts about the patient's situation' (md: 5%), 'concrete problem-solving' (md: 6%) and 'process' (md: 3%). The findings suggest that a restorative function of staff's wellbeing in Moral Case Deliberation is needed, as this might contribute to good patient care. This supports outcome criteria of improved emotional support, which may include relief of moral distress. However, facilitators need a strategy for how to proceed from the participants' own emotional needs and to develop the use of their emotional knowing to focus on

    Full Text Available The purpose of this study was to investigate how the use of the computer simulations program VPython facilitated students’ conceptual understanding of fundamental physical principles and in constructing new knowledge of physics. We focused on students in a calculus-based introductory physics course, based on the Matter and Interactions curriculum of Chabay & Sherwood (2002 at a large state engineering and science university in the USA. A major emphasis of this course was on computer modeling by using VPython to write pro¬grams simulating physical systems. We conducted multiple student interviews, as well as an open-ended exit survey, to find out student views on how creating their own simulations to enhanced-conceptual understanding of physics and in constructing new knowledge of phys¬ics. The results varied in relation to the phases when the interviews were conducted. At the beginning of the course, students viewed the simulation program as a burden. However, dur¬ing the course, students stated that it promoted their knowledge and better conceptual understanding of physical phenomena. We deduce that VPython computer simulations can improve students’ conceptual understanding of fundamental physical concepts and promote construction of new knowledge in physics, once they overcome the initial learning curve associated with the VPython software package.

    The Lawson Classroom Test of Scientific Reasoning (LCTSR) was used to gauge the relative effectiveness of three different methods of pedagogy, Reading, Presenting, and Questioning (RPQ), Experimenting and Discussion (ED), and Traditional Methods (TM), on increasing students' level of scientific thinking. The data of a one-semester-long senior high-school project indicate that, for the LCTSR: (a) the RPQ group (n = 91) achieved effect-sizes d = 0.30 and (b) the ED group (n  =  85) attained effect-sizes d = 0.64. These methods have shown that the Piagetian and Vygotskian visions on learning and teaching can go hand in hand and as such achieve respectable results. To do so, it is important to challenge the students and thus encourage the shift towards higher levels of reasoning. This aim is facilitated through class management which recognizes the importance of collaborative learning. Carrying out Vygotsky's original intention to use teaching to promote cognitive development as well as subject concepts, this research has shown that it is better to have students experience cognitive conflict from directly observed experiments than by reflecting on reported experience from popularization papers or writings found on the internet.

    Objective. To develop, implement, and assess whether simulated patient case videos improve students' understanding of and attitudes toward cross-cultural communication in health care. Design. Third-year pharmacy students (N=159) in a health care communications course participated in a one-hour lecture and two-hour workshop on the topic of cross-cultural communication. Three simulated pharmacist-patient case vignettes highlighting cross-cultural communication barriers, the role of active listening, appropriate use of medical interpreters, and useful models to overcome communication barriers were viewed and discussed in groups of 20 students during the workshop. Assessment. A pre-lecture and post-workshop assessed the effect on students' understanding of and attitudes toward cross-cultural communication. Understanding of cross-cultural communication concepts increased significantly, as did comfort level with providing cross-cultural care. Conclusion. Use of simulated patient case videos in conjunction with an interactive workshop improved pharmacy students' understanding of and comfort level with cross-cultural communication skills and can be useful tools for cultural competency training in the curriculum.

    Phenomenon: Throughout clerkship, preceptors ask medical students questions for both assessment and teaching purposes. However, the cognitive and strategic aspects of students' approaches to managing this situation have not been explored. Without an understanding of how students approach the question and answer activity, medical educators are unable to appreciate how effectively this activity fulfills their purposes of assessment or determine the activity's associated educational effects. A convenience sample of nine 4th-year medical students participated in semistructured one-on-one interviews exploring their approaches to managing situations in which they have been challenged with questions from preceptors to which they do not know the answer. Through an iterative and recursive analytic reading of the interview transcripts, data were coded and organized to identify themes relevant to the students' considerations in answering such questions. Students articulated deliberate strategies for managing the directed questioning activity, which at times focused on the optimization of their learning but always included considerations of image management. Managing image involved projecting not only being knowledgeable but also being teachable. The students indicated that their considerations in selecting an appropriate strategy in a given situation involved their perceptions of their preceptors' intentions and preferences as well as several contextual factors. Insights: The medical students we interviewed were quite sophisticated in their understanding of the social nuances of the directed questioning process and described a variety of contextually invoked strategies to manage the situation and maintain a positive image.

    Little is known about adolescents' caffeine use, yet caffeinated soda, and more recently coffee and energy drinks, are part of youth culture. This study examines adolescents' caffeine use and, using cluster analysis, identifies three groups of caffeine users who differed in their reasons for use, expectancies, and sleep behaviors. In this high school student sample (N = 197), 95% of participants reported recent caffeine use-most often soda-where typical first use of the day was in the evening. Results reveal that adolescents in the mixed use and high soda use groups consumed similar amounts of soda, reporting significantly more use than the low caffeine use group. In contrast with high soda users, mixed users drank more coffee, expected more dependence symptoms and energy enhancement from caffeine, and were more likely to report getting up early, daytime sleepiness, and using caffeine to get through the day.

  13. “It's Sweet Without Condom”: Understanding Risky Sexual Behaviour Among Nigerian Female University Students

    2018-01-01

    Full Text Available Background: Over a million people globally acquire sexually transmitted infections (STI every day mainly through unprotected sexual contact. While the consequences of risky sexual behaviour are well documented, the literature on young educated women's perceptions of, and narratives about risky sexual behaviour is limited, and thus, it is difficult to fathom from available sources why such behaviour persists. This study examined the prevalence of sexual risk-taking and assessed female University students' knowledge of the consequences of unprotected sex and reasons why such behaviour persists. Paradoxes between their narratives and risky sexual behaviour were discussed. Methods: The study adopted a mixed study design involving a survey of 420 students selected using cluster random sampling, 20 in-depth interviews and 5 focus group discussions. The analysis of the quantitative data involves the use of descriptive and inferential statistics, while thematic content analysis was used to analyse the qualitative data. Results: High prevalence of unprotected sexual intercourse was reported and was not associated with age, year of study, place of residence and religion. The narratives of participants indicate that female university students were aware of the risks associated with unprotected sex. Participants generally condemned sexual risk-taking and asserted that freedom, peer influence, poverty, ignorance, lack of sex education, civilisation, promiscuity, and satisfying sexual urge were the reasons for the persistent risky sexual behaviour among female university students. Also, perceived reduced fun associated with condom use, nourishment of marital expectations, and equivalence of unprotected sex with trust are among the reasons for persistent sexual risk-taking among female university students. Conclusion: Our findings show that female students practice risky sexual behaviour despite having knowledge of its consequences. Change in sexual behaviour

    The Script Concordance test (SCT) measures clinical reasoning in the context of uncertainty by comparing the responses of examinees and expert clinicians. It uses the level of agreement with a panel of experts to assign credit for the examinee's answers. This study describes the development and validation of a SCT for pre-clinical medical students. Faculty from two US medical schools developed SCT items in the domains of anatomy, biochemistry, physiology, and histology. Scoring procedures utilized data from a panel of 30 expert physicians. Validation focused on internal reliability and the ability of the SCT to distinguish between different cohorts. The SCT was administered to an aggregate of 411 second-year and 70 fourth-year students from both schools. Internal consistency for the 75 test items was satisfactory (Cronbach's alpha = 0.73). The SCT successfully differentiated second- from fourth-year students and both student groups from the expert panel in a one-way analysis of variance (F(2,508) = 120.4; p students from the two schools were not significantly different (p = 0.20). This SCT successfully differentiated pre-clinical medical students from fourth-year medical students and both cohorts of medical students from expert clinicians across different institutions and geographic areas. The SCT shows promise as an easy-to-administer measure of "problem-solving" performance in competency evaluation even in the beginning years of medical education.

    they discussed the validation of their beliefs. That is, we argue that the unit, and the emphases contained within the unit, resulted in the "epistemic scaffolding" of their ideas, to the extent that they shifted from arguing from anecdotes to arguing based on other types of data, especially from line graphs. Additionally, we found that students' understandings of climate change were tied to their ontological constructions of the subject matter, i.e., many perceived climate change as just another environmentally sensitive issue such as littering and pollution, and were therefore limited in their ability to understand anthropogenic climate change in the vast and robust sense meant by current scientific consensus. Given these known difficulties, it is critical to explore further research of this sort in order to better understand what students are actually thinking, and how that thinking is prone to change, modification, or not. Subsequently, K-12 strategies might be better designed, if that is indeed a priority of US/Western society.
