    Learning science requires higher-level (critical) thinking skills that need to be practiced in science classes. This study tested the effect of exam format on critical-thinking skills. Multiple-choice (MC) testing is common in introductory science courses, and students in these classes tend to associate memorization with MC questions and may not see the need to modify their study strategies for critical thinking, because the MC exam format has not changed. To test the effect of exam format, I used two sections of an introductory biology class. One section was assessed with exams in the traditional MC format, the other section was assessed with both MC and constructed-response (CR) questions. The mixed exam format was correlated with significantly more cognitively active study behaviors and a significantly better performance on the cumulative final exam (after accounting for grade point average and gender). There was also less gender-bias in the CR answers. This suggests that the MC-only exam format indeed hinders critical thinking in introductory science classes. Introducing CR questions encouraged students to learn more and to be better critical thinkers and reduced gender bias. However, student resistance increased as students adjusted their perceptions of their own critical-thinking abilities. PMID:22949426

    2013-12-01

    As part of the NSF funded Visualizing the Chemistry of Climate Change (VC3) project, we have developed a chemistry of climate science diagnostic instrument for use in general chemistry courses based on twenty-four student interviews. We have based our interview protocol on misconceptions identified in the research literature and the essential principles of climate change outlined in the CCSP document that pertain to chemistry (CCSP, 2009). The undergraduate student interviews elicited their understanding of the greenhouse effect, global warming, climate change, greenhouse gases, climate, and weather, and the findings from these interviews informed and guided the development of the multiple-choice diagnostic instrument. Our analysis and findings from the interviews indicate that students seem to confuse the greenhouse effect, global warming, and the ozone layer and in terms of chemistry concepts, the students lack a particulate level understanding of greenhouse gases causing them to not fully conceptualize the greenhouse effect and climate change. Details of the findings from the interviews, development of diagnostic instrument, and preliminary findings from the full implementation of the diagnostic instrument will be shared.

    2010-04-01

    This thesis investigates the use of problem-specific knowledge to enhance a genetic algorithm approach to multiple-choice optimisation problems.It shows that such information can significantly enhance performance, but that the choice of information and the way it is included are important factors for success.Two multiple-choice problems are considered.The first is constructing a feasible nurse roster that considers as many requests as possible.In the second problem, shops are allocated to locations in a mall subject to constraints and maximising the overall income.Genetic algorithms are chosen for their well-known robustness and ability to solve large and complex discrete optimisation problems.However, a survey of the literature reveals room for further research into generic ways to include constraints into a genetic algorithm framework.Hence, the main theme of this work is to balance feasibility and cost of solutions.In particular, co-operative co-evolution with hierarchical sub-populations, problem structure exploiting repair schemes and indirect genetic algorithms with self-adjusting decoder functions are identified as promising approaches.The research starts by applying standard genetic algorithms to the problems and explaining the failure of such approaches due to epistasis.To overcome this, problem-specific information is added in a variety of ways, some of which are designed to increase the number of feasible solutions found whilst others are intended to improve the quality of such solutions.As well as a theoretical discussion as to the underlying reasons for using each operator,extensive computational experiments are carried out on a variety of data.These show that the indirect approach relies less on problem structure and hence is easier to implement and superior in solution quality.

    Cheating in examinations is acknowledged by an increasing number of organizations to be widespread. We examine two different approaches to assess their effectiveness at detecting anomalous results, suggestive of collusion, using data taken from a number of multiple-choice examinations organized by the UK Radio Communication Foundation. Analysis of student pair overlaps of correct answers is shown to give results consistent with more orthodox statistical correlations for which confidence limits as opposed to the less familiar "Bonferroni method" can be used. A simulation approach is also developed which confirms the interpretation of the empirical approach.

  1. Multiple-choice tests stabilize access to marginal knowledge.

    PubMed

    Cantor, Allison D; Eslick, Andrea N; Marsh, Elizabeth J; Bjork, Robert A; Bjork, Elizabeth Ligon

    2015-02-01

    Marginal knowledge refers to knowledge that is stored in memory, but is not accessible at a given moment. For example, one might struggle to remember who wrote The Call of the Wild, even if that knowledge is stored in memory. Knowing how best to stabilize access to marginal knowledge is important, given that new learning often requires accessing and building on prior knowledge. While even a single opportunity to restudy marginal knowledge boosts its later accessibility (Berger, Hall, & Bahrick, 1999), in many situations explicit relearning opportunities are not available. Our question is whether multiple-choice tests (which by definition expose the learner to the correct answers) can also serve this function and, if so, how testing compares to restudying given that tests can be particularly powerful learning devices (Roediger & Karpicke, 2006). In four experiments, we found that multiple-choice testing had the power to stabilize access to marginal knowledge, and to do so for at least up to a week. Importantly, such tests did not need to be paired with feedback, although testing was no more powerful than studying. Overall, the results support the idea that one's knowledge base is unstable, with individual pieces of information coming in and out of reach. The present findings have implications for a key educational challenge: ensuring that students have continuing access to information they have learned. PMID:25201690

  2. Registered nurses' ideas of physical science concepts relevant to their clinical practice

    Wilkes, Lesley M.; Batts, Judith E.

    1996-09-01

    Experience in teaching science to nurses has raised the question of whether nurses' expressions of their understanding of concepts in physical science are adequate for professional practice. Nurses' descriptions of physical science concepts relevant to their practice must be explicated before educators can develop strategies to enhance nurses' learning of science. A cross-sectional study was undertaken to establish registered nurses' conceptions of physical science in their clinical practice. Data were collected using a multiple choice question survey, field work and focused interviews. Six categories of conceptions emerged from data analysis. Of the three which related to complexity of understanding “association” and “definition” were predominant and related in the main, to two of the three contextual categories “instrumentation/equipment” and “procedure.” There were few examples of the other two categories of “elaboration” and “body processes.” We argue that the conceptions held by the nurses were not adequate to allow them to fulfil their roles as professional practitioners in health care.

    PubMed

    Nikitin, V S

    1981-01-01

    Delayed reactions were studied on six rhesus macaques and three chimpanzees by means of a modified multiple choice method. The data obtained showed that the initial capacity of short-term memory did not exceed the reproduction of two spatial discrete elements in macaques and of three elements of shimpanzees. It was found that successful operation with sets beyond the initial capacity of short-term memory did not exceed the reproduction of two spatial discrete elements in macaques and of three elements in shimpanzees. It was found that successful operation with sets beyond the initial capacity of short-term memory is due to secondary processes of formation of visual engrams and related motor stereotypes. The significance of extension of short-time memory capacity for the transition of higher animals from monodetermined reactions to active relations with their surroundings is discussed. PMID:7281991

    This paper provides a comprehensive review of the multiple-choice assessment in the past two decades for facilitating people to conduct effective testing in various subject areas. It was revealed that a variety of multiple-choice test methods viz. conventional multiple-choice, liberal multiple-choice, elimination testing, confidence marking, probability testing, and order-of-preference scheme are available for use in assessing subjects' knowledge and decision ability. However, the best multiple-choice test method for use has not yet been identified. The review also indicated that the existence of gender differences in multiple-choice task performance might be due to the test area, instruction/scoring condition, and item difficulty.

    2012-01-01

    The role of changes of mind and multiple choices has recently received increased attention in the study of perceptual decision-making. Previously, these extensions to standard two-alternative tasks have been studied separately. Here we explored how changes of mind depend on the number of choice-alternatives. To this end, we tested 14 human subjects on a 2- and 4-alternative direction-discrimination task. Changes of mind in the participants' movement trajectories could be observed for two and for four choice alternatives. With fewer alternatives, participants responded faster and more accurately. The frequency of changes of mind, however, did not significantly differ for the different numbers of choice alternatives. Nevertheless, mind-changing improved the participants' final performance, particularly for intermediate difficulty levels, in both experimental conditions. Moreover, the mean reaction times of individual participants were negatively correlated with their overall tendency to make changes of mind. We further reproduced these findings with a multi-alternative attractor model for decision-making, while a simple race model could not account for the experimental data. Our experiment, combined with the theoretical models allowed us to shed light on: (1) the differences in choice behavior between two and four alternatives, (2) the differences between the data of our human subjects and previous monkey data, (3) individual differences between participants, and (4) the inhibitory interaction between neural representations of choice alternatives.

    2010-05-01

    Transportation programming, a process of selecting projects for funding given budget and other constraints, is becoming more complex as a result of new federal laws, local planning regulations, and increased public involvement. This article describes the use of an integer programming tool, Multiple Choice Knapsack Problem (MCKP), to provide optimal solutions to transportation programming problems in cases where alternative versions of projects are under consideration. In this paper, optimization methods for use in the transportation programming process are compared and then the process of building and solving the optimization problems is discussed. The concepts about the use of MCKP are presented and a real-world transportation programming example at various budget levels is provided. This article illustrates how the use of MCKP addresses the modern complexities and provides timely solutions in transportation programming practice. While the article uses transportation programming as a case study, MCKP can be useful in other fields where a similar decision among a subset of the alternatives is required. PMID:19596437

  8. Knowledge assessment: Squeezing information from multiple-choice testing.

    PubMed

    Nickerson, Raymond S; Butler, Susan F; Carlin, Michael T

    2015-06-01

    Knowledge assessment via testing can be viewed from two vantage points: that of the test administrator and that of the test taker. From the administrator's perspective, the objective is to discover what an individual knows about a domain of interest. From that of the test taker, the challenge is to reveal what one knows. In this article we describe a procedure for administering and scoring multiple-choice tests that satisfies both of these objectives and we present experimental data that demonstrate its effectiveness. The method allows test takers to provide specific information about their confidence that each alternative for an item is the correct answer and makes guessing not only unnecessary but detrimental. From this information the administrator can derive measures of both knowledge and confidence, which, we argue, provides better estimates than systems that do not allow measurement of partial knowledge. The use of such measures for purposes of evaluation both of individual test takers' knowledge of a subject of interest and of the effectiveness of instruction with respect to that subject is discussed.

    BACKGROUND: Several studies during the last decades have shown that answer changing in multiple choice examinations is generally beneficial for examinees. In spite of this the common misbelief still prevails that answer changing in multiple choice examinations results in an increased number of wrong answers rather than an improved score. One suggested consequence of newer studies is that examinees should

    The greenhouse effect comes up in most discussions about climate and is a key concept related to climate change. Existing studies have shown that students and adults alike lack a detailed understanding of this important concept or might hold misconceptions. We studied the effectiveness of different interventions on University-level students' understanding of the greenhouse effect. Introductory level science students were tested for their pre-knowledge of the greenhouse effect using validated multiple-choice questions, short answers and concept sketches. All students participated in a common lesson about the greenhouse effect and were then randomly assigned to one of two lab groups. One group explored an existing simulation about the greenhouse effect (PhET-lesson) and the other group worked with absorption spectra of different greenhouse gases (Data-lesson) to deepen the understanding of the greenhouse effect. All students completed the same assessment including multiple choice, short answers and concept sketches after participation in their lab lesson. 164 students completed all the assessments, 76 completed the PhET lesson and 77 completed the data lesson. 11 students missed the contrasting lesson. In this presentation we show the comparison between the multiple-choice questions, short answer questions and the concept sketches of students. We explore how well each of these assessment types represents student's knowledge. We also identify items that are indicators of the level of understanding of the greenhouse effect as measured in correspondence of student answers to an expert mental model and expert responses. Preliminary data analysis shows that student who produce concept sketch drawings that come close to expert drawings also choose correct multiple-choice answers. However, correct multiple-choice answers are not necessarily an indicator that a student produces an expert-like correlating concept sketch items. Multiple-choice questions that require detailed knowledge of the greenhouse effect (e.g. direction of re-emission of infrared energy from greenhouse gas) are significantly more likely to be answered correctly by students who also produce expert-like concept sketch items than by students who don't include this aspect in their sketch and don't answer the multiple choice questions correctly. This difference is not as apparent for less technical multiple-choice questions (e.g. type of radiation emitted by Sun). Our findings explore the formation of student's mental models throughout different interventions and how well the different assessment techniques used in this study represent the student understanding of the overall concept.

    2015-01-01

    Benford’s Law describes the finding that the distribution of leading (or leftmost) digits of innumerable datasets follows a well-defined logarithmic trend, rather than an intuitive uniformity. In practice this means that the most common leading digit is 1, with an expected frequency of 30.1%, and the least common is 9, with an expected frequency of 4.6%. Currently, the most common application of Benford’s Law is in detecting number invention and tampering such as found in accounting-, tax-, and voter-fraud. We demonstrate that answers to end-of-chapter exercises in physics and chemistry textbooks conform to Benford’s Law. Subsequently, we investigate whether this fact can be used to gain advantage over random guessing in multiple-choice tests, and find that while testbank answers in introductory physics closely conform to Benford’s Law, the testbank is nonetheless secure against such a Benford’s attack for banal reasons.

    In this article we discuss the findings of our research on students' understanding of vector concepts in problems without physical context. First, we develop a complete taxonomy of the most frequent errors made by university students when learning vector concepts. This study is based on the results of several test administrations of open-ended problems in which a total of 2067 students participated. Using this taxonomy, we then designed a 20-item multiple-choice test [Test of understanding of vectors (TUV)] and administered it in English to 423 students who were completing the required sequence of introductory physics courses at a large private Mexican university. We evaluated the test's content validity, reliability, and discriminatory power. The results indicate that the TUV is a reliable assessment tool. We also conducted a detailed analysis of the students' understanding of the vector concepts evaluated in the test. The TUV is included in the Supplemental Material as a resource for other researchers studying vector learning, as well as instructors teaching the material.

    Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning.

    2014-11-01

    We describe a simple model of heterogeneous, interacting agents making decisions between n?2 discrete choices. For a special class of interactions, our model is the mean field description of random field Potts-like models and is effectively solved by finding the extrema of the average energy E per agent. In these cases, by studying the propagation of decision changes via avalanches, we argue that macroscopic dynamics is well captured by a gradient flow along E. We focus on the permutation symmetric case, where all n choices are (on average) the same, and spontaneous symmetry breaking (SSB) arises purely from cooperative social interactions. As examples, we show that bimodal heterogeneity naturally provides a mechanism for the spontaneous formation of hierarchies between decisions and that SSB is a preferred instability to discontinuous phase transitions between two symmetric points. Beyond the mean field limit, exponentially many stable equilibria emerge when we place this model on a graph of finite mean degree. We conclude with speculation on decision making with persistent collective oscillations. Throughout the paper, we emphasize analogies between methods of solution to our model and common intuition from diverse areas of physics, including statistical physics and electromagnetism.

    2008-01-01

    This article discusses the advantages of using wireless keypads in the Lecture/classroom. This new technology requires multiple-choice (MC) questions to mate with the keypad entry features of these devices. The format of the traditional MC response is constrained to five choices and only one best response is allowed. For this reason, we propose enhancements to the traditional MC question. This enhanced MC question allows as many as ten answers. The answers can vary in their degree of correctness and can be assigned partial credit. By combining wireless keypads and multiple-choice questions, we can readily perform both formative and summative assessments of student learning. Examples and classroom applications are presented.

  14. BOOK REVIEW: Key Science Physics: New Edition and Key Science Physics for International Schools: Extension File

    NASA Astrophysics Data System (ADS)

    Maybank, Maureen

    1999-09-01

    When handling , I recalled how one set of sixth-form students that I taught affectionately referred to Jim Breithaupt's large format book Understanding Physics for Advanced Level as `Big Jim'. This package, for GCSE students and teachers, is its younger brother. Key Science Physics was reviewed in this journal over four years ago. Now it is in a new edition with an expanded ring file of teacher resources (a Teacher's Guide and Extension File). It has been expanded for a wider range of students to meet the requirements of all GCSE syllabuses with additional topics for IGCSE and IB. The international bit seems to be among materials in the file of resources and does not appear in the title of the students' textbook. This is not one of those purchases that will only get occasional use and be left in a department library but it is one that contains sufficient excellent material to become central to any GCSE Physics course. For the students there is a single-volume 396-page textbook in full colour (not a heavyweight book). Marginal comments point out places where an Activity or Assignment from the Extension File fits in. All the materials in the teacher's Extension File are cross referenced to the numbering of this textbook, i.e. its Themes, Topics, Checkpoints, Tests etc, not to page numbers. The margin is used in other attractive ways to highlight a summary, propose a first thought or provide a topic summary. The text is fruitful mix of pure physics, applications and personalities. To support the students' practical work the Extension File contains photocopiable sheets. For the activities and assignments a few contain a harder version to give access to the higher levels of attainment. Four alternatives to practical questions are given; there are also exam questions and multiple choice questions for each topic. These all have helpful mark schemes on the teacher's answers pages. What else do you get? A Glossary collection of sheets to photocopy with space to enter a definition in a second language. Versions of many key diagrams in the student book are enlarged and reworked in clear black and white to make OHP transparencies. There is a mention of these also being in colour on a CD-ROM. The organization of the Extension File is as clear as is reasonably possible. As a user, I would add coloured page dividers to mark the sections within it. The Teacher's Guide is admirable in its restraint - just 26 sides of topic notes - which includes the answers to the non-numerical checkpoint questions missing in the student book. It is not wordy or full of educational theory but succinct and relevant to the day-to-day business of learning with these materials. Reading it, I was aware of the snags that a novice teacher might be glad to know but were missing. As always, materials like these should come with a health warning - try out all homework sheets, instructions for activities and assignments before your students!

  15. Map of the Physical Sciences

    SciTech Connect

    Boyack, Kevin W.

    1999-07-02

    Various efforts to map the structure of science have been undertaken over the years. Using a new tool, VxInsight{trademark}, we have mapped and displayed 3000 journals in the physical sciences. This map is navigable and interactively reveals the structure of science at many different levels. Science mapping studies are typically focused at either the macro-or micro-level. At a macro-level such studies seek to determine the basic structural units of science and their interrelationships. The majority of studies are performed at the discipline or specialty level, and seek to inform science policy and technical decision makers. Studies at both levels probe the dynamic nature of science, and the implications of the changes. A variety of databases and methods have been used for these studies. Primary among databases are the citation indices (SCI and SSCI) from the Institute for Scientific Information, which have gained widespread acceptance for bibliometric studies. Maps are most often based on computed similarities between journal articles (co-citation), keywords or topics (co-occurrence or co-classification), or journals (journal-journal citation counts). Once the similarity matrix is defined, algorithms are used to cluster the data.

    The Astronomical Approach to Physical Science Curriculum (AAPS Curriculum) is an innovative curriculum that incorporates an astronomy theme into an inquiry-based physical science curriculum for pre-service, elementary school teachers. Many physical science courses are a non-cohesive collection of topics required for the state teaching license. Through the use of astronomy and space science examples, the AAPS Curriculum will have a coherent theme that ties the wide variety of physical science topics together and provides many real world applications for the topics covered in the course. This new curriculum will incorporate the applications of knowledge to complete the learning cycle-exploration, concept introduction, application. Astronomy and space science applications will be emphasized throughout the curriculum. The theme of astronomy was chosen to prepare elementary school teachers for teaching astronomy and space science in their classroom, as this is a topic in which many school children are consistently interested. Since astronomy is a topic that can be used as a springboard to teach many other areas of study, we want teachers who are knowledgeable in topics of astronomy so they are capable of preparing creative lessons throughout their entire curriculum that are exciting to their students. The AAPS Curriculum will train college students to become teachers who are comfortable with physical science and astronomy topics and who are excited to teach these topics in their classroom. Funding for this work is provided by the IDEAS grant program of the Space Telescope Science Institute.

  9. Pick-N multiple choice-exams: a comparison of scoring algorithms.

    2011-05-01

    To compare different scoring algorithms for Pick-N multiple correct answer multiple-choice (MC) exams regarding test reliability, student performance, total item discrimination and item difficulty. Data from six 3rd year medical students' end of term exams in internal medicine from 2005 to 2008 at Munich University were analysed (1,255 students, 180 Pick-N items in total). Scoring Algorithms: Each question scored a maximum of one point. We compared: (a) Dichotomous scoring (DS): One point if all true and no wrong answers were chosen. (b) Partial credit algorithm 1 (PS(50)): One point for 100% true answers; 0.5 points for 50% or more true answers; zero points for less than 50% true answers. No point deduction for wrong choices. (c) Partial credit algorithm 2 (PS(1/m)): A fraction of one point depending on the total number of true answers was given for each correct answer identified. No point deduction for wrong choices. Application of partial crediting resulted in psychometric results superior to dichotomous scoring (DS). Algorithms examined resulted in similar psychometric data with PS(50) only slightly exceeding PS(1/m) in higher coefficients of reliability. The Pick-N MC format and its scoring using the PS(50) and PS(1/m) algorithms are suited for undergraduate medical examinations. Partial knowledge should be awarded in Pick-N MC exams. PMID:21038082

    Aims: In most German medical faculties, credits in general practice can be earned via exams using multiple-choice questions (MCQ). Measures such as peer-reviews may help assure the quality of these exams. In order to use time and personnel intensive peer reviews effectively and efficiently, the procedures used are key. Therefore, we wanted to find out whether there are differences between group and individual reviews regarding defined parameters. Methods: We conducted a controlled cross-over study with three GP reviewers from four different German universities. Each reviewed 80 MCQs, 40 individually and 40 within a group, including external assessments by a panel of experts. Furthermore all reviewers were asked to evaluate the review process and the time spent carrying out these reviews. Outcomes: We found no significant differences between the reliability and the validity of individual reviews versus group reviews. On average slightly more time was spent on group reviews compared with the individual reviews. The subjective assessments of the study participants regarding their satisfaction with the process and the efficiency and effectiveness of the reviews suggest a preference for group reviews. Conclusions: Based on this study, there are no definite recommendations for or against either approach. When choosing between the two, the specific work structures and organisation at the local faculty should be taken into account. PMID:22916083

    In this study, a new physics education programme is specifically developed for a famous theme park in Hong Kong to provide community-based science learning to her visitors, involving her three newly constructed rides. We make innovative use of digital technologies in this programme and incorporate a rigorous evaluation of the learning effectiveness of the programme. A total of around 200 students from nine local secondary schools participated in both the physics programme and its subsequent evaluation which consists of a combination of research and assessment tools, including pre- and post-multiple-choice tests, a questionnaire survey and an interview as specifically developed for this programme, or adopted from some well-accepted research instruments. Based on the evaluation of students' academic performance, there are two educationally significant findings on enhancing the students' physics learning: (a) traditionally large gender differences in physics performance and interest of learning are mostly eliminated; and (b) a less-exciting ride called the aviator (instead of the most exciting roller-coaster ride) can induce the largest learning effect (or gain in academic performance) amongst teenagers. Besides, findings from the questionnaire survey and interviews of participants are reported to reveal their views, perceptions, positive and negative comments or feedback on this programme which could provide valuable insights for future development of other similar community-based programmes.

    It is critically important that national and international science policy be scientifically grounded. To this end, the next generation of scientists and engineers will need to be technically competent, effective communicators of science, and engaged advisors in the debate and formulation of science policy. We describe three science policy debates developed for the physics classroom aimed at encouraging students to draw connections between their developing technical expertise and important science policy issues. The first debate considers the proposal for a 450-megawatt wind farm on public lands in Nantucket Sound and fits naturally into the curriculum related to alternative forms of energy production. The second debate considers national fuel-economy standards for sport-utility vehicles and can be incorporated into the curriculum related to heat engines. The third debate, suitable for the curriculum in optics, considers solid state lighting and implications of recent United States legislation that places stringent new energy-efficiency and reliability requirements on conventional lighting. The technical foundation for each of these debates fits naturally into the undergraduate physics curriculum and the material is suitable for a wide range of physics courses, including general science courses for non-majors.

    1995-01-01

    This report by the Committee on Solar and Space Physics and the Committee on Solar-Terrestrial Research recommends the major directions for scientific research in space physics for the coming decade. As a field of science, space physics has passed through the stage of simply looking to see what is out beyond Earth's atmosphere. It has become a 'hard' science, focusing on understanding the fundamental interactions between charged particles, electromagnetic fields, and gases in the natural laboratory consisting of the galaxy, the Sun, the heliosphere, and planetary magnetospheres, ionospheres, and upper atmospheres. The motivation for space physics research goes far beyond basic physics and intellectual curiosity, however, because long-term variations in the brightness of the Sun virtually affect the habitability of the Earth, while sudden rearrangements of magnetic fields above the solar surface can have profound effects on the delicate balance of the forces that shape our environment in space and on the human technology that is sensitive to that balance. The several subfields of space physics share the following objectives: to understand the fundamental laws or processes of nature as they apply to space plasmas and rarefied gases both on the microscale and in the larger complex systems that constitute the domain of space physics; to understand the links between changes in the Sun and the resulting effects at the Earth, with the eventual goal of predicting the significant effects on the terrestrial environment; and to continue the exploration and description of the plasmas and rarefied gases in the solar system.

  4. Enhancing Interdisciplinary, Mathematics, and Physical Science in an Undergraduate Life Science Program through Physical Chemistry

    PubMed Central

    2009-01-01

    BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of the undergraduate biology curriculum. The Department of Chemistry and Life Science at West Point responded by developing a required physical chemistry course tailored to the interests of life science majors. To overcome student resistance to physical chemistry, students were enabled as long-term stakeholders who would shape the syllabus by selecting life science topics of interest to them. The initial 2 yr of assessment indicates that students have a positive view of the course, feel they have succeeded in achieving course outcome goals, and that the course is relevant to their professional future. Instructor assessment of student outcome goal achievement via performance on exams and labs is comparable to that of students in traditional physical chemistry courses. Perhaps more noteworthy, both student and instructor assessment indicate positive trends from year 1 to year 2, presumably due to the student stakeholder effect. PMID:19255133

    Potvin, Patrice; Turmel, Élaine; Masson, Steve

    2014-01-01

    Functional magnetic resonance imaging was used to identify the brain-based mechanisms of uncertainty and certainty associated with answers to multiple-choice questions involving common misconceptions about electric circuits. Twenty-two scientifically novice participants (humanities and arts college students) were asked, in an fMRI study, whether or not they thought the light bulbs in images presenting electric circuits were lighted up correctly, and if they were certain or uncertain of their answers. When participants reported that they were unsure of their responses, analyses revealed significant activations in brain areas typically involved in uncertainty (anterior cingulate cortex, anterior insula cortex, and superior/dorsomedial frontal cortex) and in the left middle/superior temporal lobe. Certainty was associated with large bilateral activations in the occipital and parietal regions usually involved in visuospatial processing. Correct-and-certain answers were associated with activations that suggest a stronger mobilization of visual attention resources when compared to incorrect-and-certain answers. These findings provide insights into brain-based mechanisms of uncertainty that are activated when common misconceptions, identified as such by science education research literature, interfere in decision making in a school-like task. We also discuss the implications of these results from an educational perspective. PMID:24478680

    Minority male mating advantage was tested in wild type strains of Drosophila ananassae through multiple-choice experiments. Mating success of two types of flies present in five different ratios was scored by direct observation in an Elens-Wattiaux mating chamber. We found no evidence for minority male mating advantage in wild type strains of D. ananassae. The relative mating success of two types of females was also compared in the multiple-choice experiments at different ratios; there was no evidence for a rare female effect. Further, there was similarity in the results of experiments employing different methods. The total number of homogamic and heterogamic matings was obtained by combining the data (all five ratios) from each experiment. Homogamic matings were significantly more frequent than heterogamic ones, which demonstrates preferential mating between males and females of the same strain; this was also supported by a lower isolation estimate. There was also a significant difference in the degree of mating preference between the two strains. PMID:14963822

  8. The Effect of Question Order on Responses to Multiple-choice Questions

    NSDL National Science Digital Library

    Gray, Kara

    This paper, presented at the 2002 Physics Education Research Conference, investigates how the order of two related FCI questions (#13 and 14) affects students' responses. This study also investigates the effect an unrelated FCI question (#23) has on answers to the above problems. Four versions of a survey were administered before and after instruction to 243 students taking an algebra-based physics class. Versions 1 and 2 of the survey included the related physics questions in opposite order. Versions 3 and 4 included the unrelated physics question and one of the above questions. Student responses for the four versions were compared for both the pre- and post-instruction surveys.

    We present the results of our efforts to incorporate the latest developments in Web technology and pedagogical techniques into an introductory conceptual physical science course. The course is a freshman general education course which teaches principles of physics, chemistry, and geology. The work combines the efforts from faculty in each of these departments. Web presentation of the material uses email, FLASH, Java applets, Director animations, electronic quizzes with remedial correction, and digital video. The frustrations and the thrills that go with developing such a course are discussed and examples of lessons which incorporate the philosophy of the course and our pedagogical approach are shown. We have tested a sample of these lessons in two sections of the class alternating between web-based and paper-based assignments in each section. We present student reactions to using these resources and a statistical assessment of how they influenced student learning.

    Physics education reform movements should pay attention to feminist analyses of gender in the culture of physics for two reasons. One reason is that feminist analyses contribute to an understanding of a ‘chilly climate’ women encounter in many physics university departments. Another reason is that feminist analyses reveal that certain styles of doing science are predominant in the culture of physics. I introduce recent philosophical work in social epistemology to argue that the predominance of certain styles of doing science is not good for science. Scientific communities would benefit from greater diversity in styles of doing science.

  18. Web-MCQ: a set of methods and freely available open source code for administering online multiple choice question assessments.

    PubMed

    Hewson, Claire

    2007-08-01

    E-learning approaches have received increasing attention in recent years. Accordingly, a number of tools have become available to assist the nonexpert computer user in constructing and managing virtual learning environments, and implementing computer-based and/or online procedures to support pedagogy. Both commercial and free packages are now available, with new developments emerging periodically. Commercial products have the advantage of being comprehensive and reliable, but tend to require substantial financial investment and are not always transparent to use. They may also restrict pedagogical choices due to their predetermined ranges of functionality. With these issues in mind, several authors have argued for the pedagogical benefits of developing freely available, open source e-learning resources, which can be shared and further developed within a community of educational practitioners. The present paper supports this objective by presenting a set of methods, along with supporting freely available, downloadable, open source programming code, to allow administration of online multiple choice question assessments to students.

    2015-05-01

    The advantages of metaphorical representation are pointed out in many fields of clinical research (e.g. cancer, HIV, psychogenic nonepileptic seizures). This study aimed at offering a novel contribution showing how children with epilepsy describe the symptomatology of their seizure experiences by means of particular kinds of cognitive metaphors. Twenty-three children with idiopathic generalized epilepsy and thirty-one healthy children were recruited for this study and interviewed with a multiple-choice questionnaire asking them to describe their epileptic seizures by means of suitable metaphors. A psychologist blinded to medical diagnosis assessed and categorized all metaphors. By considering the 89 metaphors produced by the children with epilepsy and the 147 ones by the healthy controls, Agent/Force was the primary metaphor assessed by children with epilepsy, followed by Event/Situation as the second preference. Moreover, comparing the results of the control group with those of the subjects with epilepsy, it was found that controls were oriented towards selecting exogenous forces, while subjects with epilepsy tended to select endogenous forces. In particular, children with epilepsy showed a peculiar preference for an endogenous force resembling the waggle metaphor, which is similar to the effect of a quake's shaking (earthquake or seaquake). The metaphors identified by this research are a useful resource to better understand the seizure experiences of patients with epilepsy, helping to improve clinical treatment. PMID:25934584

  20. Education techniques for lifelong learning: writing multiple-choice questions for continuing medical education activities and self-assessment modules.

    PubMed

    Collins, Jannette

    2006-01-01

    The multiple-choice question (MCQ) is the most commonly used type of test item in radiologic graduate medical and continuing medical education examinations. Now that radiologists are participating in the maintenance of certification process, there is an increased need for self-assessment modules that include MCQs and persons with test item-writing skills to develop such modules. Although principles of effective test item writing have been documented, violations of these principles are common in medical education. Guidelines for test construction are related to development of educational objectives, defining levels of learning for each objective, and writing effective MCQs that test that learning. Educational objectives should be written in observable, behavioral terms that allow for an accurate assessment of whether the learner has achieved the objectives. Learning occurs at many levels, from simple recall to problem solving. The educational objectives and the MCQs that accompany them should target all levels of learning appropriate for the given content. Characteristics of effective MCQs can be described in terms of the overall item, the stem, and the options. Flawed MCQs interfere with accurate and meaningful interpretation of test scores and negatively affect student pass rates. Therefore, to develop reliable and valid tests, items must be constructed that are free of such flaws. The article provides an overview of established guidelines for writing effective MCQs, a discussion of writing appropriate educational objectives and MCQs that match those objectives, and a brief review of item analysis.

    Since its discovery in 2004, graphene, a two-dimensional hexagonal carbon allotrope, has generated great interest and spurred research activity from materials science to particle physics and vice versa. In particular, graphene has been found to exhibit outstanding electronic and mechanical properties, as well as an unusual low-energy spectrum of Dirac quasiparticles giving rise to a fractional quantum Hall effect when freely suspended and immersed in a magnetic field. One of the most intriguing puzzles of graphene involves the low-temperature conductivity at zero density, a central issue in the design of graphene-based nanoelectronic components. While suspended graphene experiments have shown a trend reminiscent of semiconductors, with rising resistivity at low temperatures, most theories predict a constant or even decreasing resistivity. However, lattice field theory calculations have revealed that suspended graphene is at or near the critical coupling for excitonic gap formation due to strong Coulomb interactions, which suggests a simple and straightforward explanation for the experimental data. In this contribution we review the current status of the field with emphasis on the issue of gap formation, and outline recent progress and future points of contact between condensed matter physics and Lattice QCD.

    We evaluate accelerator science in the context of its contributions to the physics community. We address the problem of quantifying these contributions and present a scheme for a numerical evaluation of them. We show by using a statistical sample of important developments in modern physics that accelerator science has influenced 28% of post-1938 physicists and also 28% of post-1938 physics research. We also examine how the influence of accelerator science has evolved over time, and show that on average it has contributed to a physics Nobel Prize-winning research every 2.9 years.

  11. The physical science behind climate change

    2007-07-01

    For a scientist studying climate change, 'eureka' moments are unusually rare. Instead progress is generally made by a painstaking piecing together of evidence from every new temperature measurement, satellite sounding or climate-model experiment. Data get checked and rechecked, ideas tested over and over again. Do the observations fit the predicted changes? Could there be some alternative explanation? Good climate scientists, like all good scientists, want to ensure that the highest standards of proof apply to everything they discover. And the evidence of change has mounted as climate records have grown longer, as our understanding of the climate system has improved and as climate models have become ever more reliable. Over the past 20 years, evidence that humans are affecting the climate has accumulated inexorably, and with it has come ever greater certainty across the scientific community in the reality of recent climate change and the potential for much greater change in the future. This increased certainty is starkly reflected in the latest report of the Intergovernmental Panel on Climate Change (IPCC), the fourth in a series of assessments of the state of knowledge on the topic, written and reviewed by hundreds of scientists worldwide. The panel released a condensed version of the first part of the report, on the physical science basis of climate change, in February. Called the 'Summary for Policymakers,' it delivered to policymakers and ordinary people alike an unambiguous message: scientists are more confident than ever that humans have interfered with the climate and that further human-induced climate change is on the way. Although the report finds that some of these further changes are now inevitable, its analysis also confirms that the future, particularly in the longer term, remains largely in our hands--the magnitude of expected change depends on what humans choose to do about greenhouse gas emissions. The physical science assessment focuses on four topics: drivers of climate change, changes observed in the climate system, understanding cause-and-effect relationships, and projection of future changes. Important advances in research into all these areas have occurred since the IPCC assessment in 2001. In the pages that follow, we lay out the key findings that document the extent of change and that point to the unavoidable conclusion that human activity is driving it.

    Clarissa Ai Ling Lee

    2014-06-21

    The dissertation brings together approaches across the fields of physics, critical theory, literary studies, philosophy of physics, sociology of science, and history of science to synthesize a hybrid approach for instigating more rigorous and intense cross-disciplinary interrogations between the sciences and the humanities. There are two levels of conversations going on in the dissertation; at the first level, the discussion is centered on a critical historiography and philosophical implications of the discovery Higgs boson in relation to its position at the intersection of old (current) and the potential for new possibilities in quantum physics; I then position my findings on the Higgs boson in connection to the double-slit experiment that represents foundational inquiries into quantum physics, to demonstrate the bridge between fundamental physics and high energy particle physics. The conceptualization of the variants of the double-slit experiment informs the aforementioned critical comparisons. At the second level of the conversation, theories are produced from a close study of the physics objects as speculative engine for new knowledge generation that are then reconceptualized and re-articulated for extrapolation into the speculative ontology of hard science fiction, particularly the hard science fiction written with the double intent of speaking to the science while producing imaginative and socially conscious science through the literary affordances of science fiction. The works of science fiction examined here demonstrate the tension between the internal values of physics in the practice of theory and experiment and questions on ethics, culture, and morality.

    2009-01-01

    Background It is widely recognised that deficiencies in fetal surveillance practice continue to contribute significantly to the burden of adverse outcomes. This has prompted the development of evidence-based clinical practice guidelines by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists and an associated Fetal Surveillance Education Program to deliver the associated learning. This article describes initial steps in the validation of a corresponding multiple-choice assessment of the relevant educational outcomes through a combination of item response modelling and expert judgement. Methods The Rasch item response model was employed for item and test analysis and to empirically derive the substantive interpretation of the assessment variable. This interpretation was then compared to the hierarchy of competencies specified a priori by a team of eight subject-matter experts. Classical Test Theory analyses were also conducted. Results A high level of agreement between the hypothesised and derived variable provided evidence of construct validity. Item and test indices from Rasch analysis and Classical Test Theory analysis suggested that the current test form was of moderate quality. However, the analyses made clear the required steps for establishing a valid assessment of sufficient psychometric quality. These steps included: increasing the number of items from 40 to 50 in the first instance, reviewing ineffective items, targeting new items to specific content and difficulty gaps, and formalising the assessment blueprint in light of empirical information relating item structure to item difficulty. Conclusion The application of the Rasch model for criterion-referenced assessment validation with an expert stakeholder group is herein described. Recommendations for subsequent item and test construction are also outlined in this article. PMID:19402898

  8. BOOK REVIEW: Science Fair Projects: Physics

    NASA Astrophysics Data System (ADS)

    Reynolds, Helen

    2000-11-01

    I have often thought that the notion of a Science Fair is intrinsically a good one but have never set one up. With this book such an undertaking is possible, with 47 projects from which you can choose. Each project has a clearly stated purpose with an overview that contains the physics you need to get started. A hypothesis, or sometimes two, and a procedure detailing what the student should do follow this. The materials to be used are those you should be able to find at home, and safety guidelines as well as places the student needs adult help are clearly marked. Every project asks the student to write down the results of their experiment and decide whether or not their hypothesis was correct. There are also suggestions for taking each project further. Some of these projects are standard experiments that you may already do with students in class, for example, making plasticine boats, string telephones and levers. Most are interesting twists on standard experiments such as using a wedge as a simple machine, home-made spinning toys and the experiments with light bulbs. The latter are the only real cause for concern if students were to do these things at home as adult supervision would be essential. This is obviously an American book, though. Teachers in British classrooms would need to work out how to deal with the references to temperature in Fahrenheit and mass in ounces. Length is usually given in centimetres as well as inches. Translations of soda bottles and bobby pins would also be needed. This book is designed to be full of ideas and to give structure to projects students can do at home, not to provide ideas that you can transport into the classroom. It does this very well and I would recommend it to anyone thinking of starting up a Science Fair. Alternatively, this is an excellent resource for more interesting homework assignments that would put more responsibility on the student and give them something fun to do.

  9. Effect of differing PowerPoint slide design on multiple-choice test scores for assessment of knowledge and retention in a theriogenology course.

    2014-01-01

    Third-year veterinary students in a required theriogenology diagnostics course were allowed to self-select attendance at a lecture in either the evening or the next morning. One group was presented with PowerPoint slides in a traditional format (T group), and the other group was presented with PowerPoint slides in the assertion-evidence format (A-E group), which uses a single sentence and a highly relevant graphic on each slide to ensure attention is drawn to the most important points in the presentation. Students took a multiple-choice pre-test, attended lecture, and then completed a take-home assignment. All students then completed an online multiple-choice post-test and, one month later, a different online multiple-choice test to evaluate retention. Groups did not differ on pre-test, assignment, or post-test scores, and both groups showed significant gains from pre-test to post-test and from pre-test to retention test. However, the T group showed significant decline from post-test to retention test, while the A-E group did not. Short-term differences between slide designs were most likely unaffected due to required coursework immediately after lecture, but retention of material was superior with the assertion-evidence slide design.

  11. Central Cholinergic Involvement in Sequential Behavior: Impairments of Performance by Atropine in a Serial Multiple Choice Task for Rats

    PubMed Central

    Fountain, Stephen B.; Rowan, James D.; Wollan, Michael O.

    2013-01-01

    Two experiments examined whether muscarinic cholinergic systems play a role in rats’ ability to perform well-learned highly-structured serial response patterns, particularly focusing on rats’ performance on pattern elements learned by encoding rules versus by acquisition of stimulus-response (S-R) associations. Rats performed serial patterns of responses in a serial multiple choice task in an 8-lever circular array for hypothalamic brain-stimulation reward. Two experiments examined the effects of atropine, a centrally-acting muscarinic cholinergic receptor antagonist, on rats’ ability to perform pattern elements where responses were controlled by rules versus elements, such as rule-inconsistent “violation elements” and elements following “phrasing cues,” where responses were controlled by associative cues. In Experiment 1, 3-element chunks of both patterns were signaled by pauses that served as phrasing cues before chunk-boundary elements, but one pattern also included a violation element that was inconsistent with pattern structure. Once rats reached a high criterion of performance, the drug challenge was intraperitoneal injection of a single dose of 50 mg/kg atropine sulfate. Atropine impaired performance on elements learned by S-R learning, namely, chunk-boundary elements and the violation element, but had no effect on performance of rule-based within-chunk elements. In Experiment 2, patterns were phrased and unphrased perfect patterns (i.e., without violation elements). To control for peripheral effects of atropine, rats were treated with a series of doses of either centrally-acting atropine or peripherally-acting atropine methyl nitrate (AMN), which does not cross the blood-brain barrier. Once rats reached a high criterion, the drug challenges were on alternate days in the order 50, 25, and 100 mg/kg of either atropine sulfate or AMN. Atropine, but not AMN, impaired performance in the phrased perfect pattern for pattern elements where S-R associations were important for performance, namely, chunk-boundary elements. However, in the structurally more ambiguous unphrased perfect pattern where rats had fewer cues and presumably relied more on S-R associations throughout, atropine impaired performance on all pattern elements. Thus, intact muscarinic cholinergic systems were shown to be necessary for discriminative control previously established by S-R learning, but were not necessary for rule-based serial pattern performance.

    This talk will describe a course offered to Harvard undergraduates as a general education science course, meant to intrduce freshman-level science for non-science majors. The course was a collaboration between world-class chefs and science professors. The chefs introduced concepts of cooking and the professors used these to motivate scientific concepts. The lectures were designed to provide a coherent introduction to freshman physics, primarily through soft matter science. The lectures were supplemented by a lab experiments, designed by a team of very talented graduate students and post docs, that supplemented the science taught in lecture. The course was very successful in motivating non-science students to learn, and even enjoy, basic science concepts. This course depended on contributions from Michael Brenner, Otger Campas, Amy Rowat and a team of talented graduate student teaching fellows.

    The Views About Sciences Survey (VASS) is a paper-and-pencil instrument to characterize student views about knowing and learning science and assess the relation of these views to achievement in science courses. VASS shows that: (a) high school and college students have views about physics that often diverge from physicists' views, (b) student views can be grouped into four distinct profiles: expert, high transitional, low transitional, and folk, (c) profile distributions are similar in college and high school, and (d) student profiles correlate significantly with physics achievement.

    Crouch, Catherine H.; Heller, Kenneth

    2014-05-01

    We describe restructuring the introductory physics for life science students (IPLS) course to better support these students in using physics to understand their chosen fields. Our courses teach physics using biologically rich contexts. Specifically, we use examples in which fundamental physics contributes significantly to understanding a biological system to make explicit the value of physics to the life sciences. This requires selecting the course content to reflect the topics most relevant to biology while maintaining the fundamental disciplinary structure of physics. In addition to stressing the importance of the fundamental principles of physics, an important goal is developing students' quantitative and problem solving skills. Our guiding pedagogical framework is the cognitive apprenticeship model, in which learning occurs most effectively when students can articulate why what they are learning matters to them. In this article, we describe our courses, summarize initial assessment data, and identify needs for future research.

    2012-02-01

    Using data collected from a nationally-representative sample of first-year college students, we examine how students' identity development as physics persons and their likelihood to pursue a career in physical science is predicted by differing immigrant experiences. We consider broad factors having a social, economic, or cultural nature as covariates in a propensity score model that assesses differences due to immigrant generation. Our results show that, when controlling for such factors as race/ethnicity, socio-economic status, and gender, students' physics identities and the likelihood of choosing a career in physical science are significantly higher amongst first generation students than second generation (or later) students. We conclude that physical science as a career option can be influenced by the experiences of being an immigrant and through the relationship between origin and host culture.

    Bell, Morris D.; Fiszdon, Joanna M.; Greig, Tamasine C.; Wexler, Bruce E.

    2010-01-01

    This is the first report on the use of the Social Attribution Task – Multiple Choice (SAT-MC) to assess social cognitive impairments in schizophrenia. The SAT-MC was originally developed for autism research, and consists of a 64-second animation showing geometric figures enacting a social drama, with 19 multiple choice questions about the interactions. Responses from 85 community-dwelling participants and 66 participants with SCID confirmed schizophrenia or schizoaffective disorders (Scz) revealed highly significant group differences. When the two samples were combined, SAT-MC scores were significantly correlated with other social cognitive measures, including measures of affect recognition, theory of mind, self-report of egocentricity and the Social Cognition Index from the MATRICS battery. Using a cut-off score, 53% of Scz were significantly impaired on SAT-MC compared with 9% of the community sample. Most Scz participants with impairment on SAT-MC also had impairment on affect recognition. Significant correlations were also found with neurocognitive measures but with less dependence on verbal processes than other social cognitive measures. Logistic regression using SAT-MC scores correctly classified 75% of both samples. Results suggest that this measure may have promise, but alternative versions will be needed before it can be used in pre-post or longitudinal designs. PMID:20400268

    We are in the midst of a revolution in physics. Observing the cosmos has provided compelling evidence for physics beyond the Standard Model of particle physics: non-zero neutrino masses, non-baryonic dark matter, dark energy and primordial inflation. Together with ordinary matter these constituents determine the structure of the Universe. The necessary, but puzzling, connection between the inner space of quantum reality and outer space of cosmic reality will enable the discovery of new particle physics through astrophysical observations and may reconcile quantum mechanics and general relativity in a new synthesis: a Standard Model of the Universe. LSST will significantly contribute to answering the following questions: What is dark energy? What is dark matter? What are the neutrino masses? Was primordial inflation responsible for the origin of large-scale structure (LSS)? Did it leave observable imprints that can shed light on the unification of the fundamental forces? Can gravity be described in a unified quantum framework with the other forces? Precision cosmological observations will enable falsification of models covering the inflationary epoch, through the “dark ages”, to the first generation of stars and galaxies, and the current cosmic acceleration. LSST will study the impact of dark energy on both the history of cosmic expansion and growth of LSS using diverse techniques based on: weak-lensing, baryon acoustic oscillations, supernovae, galaxy cluster counts and strong lensing of quasars. Inconsistencies in the results may signal deficiencies in General Relativity and the need for a new theory of gravity. Properties of dark matter will be gleaned by studying the evolution of structure and by strong-lensing of galaxies, quasars and supernovae. Precision measurements of the matter power spectra vs cosmic time will constrain the sum of neutrino masses. LSST will probe inflation using cosmic shear and the spatial power spectrum of galaxies.

  8. Courses in Modern Physics for Non-science Majors, Future Science Teachers, and Biology Students

    2001-03-01

    For the past 15 years Kansas State University has offered a course in modern physics for students who are not majoring in physics. This course carries a prerequisite of one physics course so that the students have a basic introduction in classical topics. The majors of students range from liberal arts to engineering. Future secondary science teachers whose first area of teaching is not physics can use the course as part of their study of science. The course has evolved from a lecture format to one which is highly interactive and uses a combination of hands-on activities, tutorials and visualizations, particularly the Visual Quantum Mechanics materials. Another course encourages biology students to continue their physics learning beyond the introductory course. Modern Miracle Medical Machines introduces the basic physics which underlie diagnosis techniques such as MRI and PET and laser surgical techniques.

    Hinko, Kathleen; Finkelstein, Noah D.

    2013-01-01

    Informal education programs organized by university physics departments are a popular means of reaching out to communities and satisfying grant requirements. The outcomes of these programs are often described in terms of broader impacts on the community. Comparatively little attention, however, has been paid to the influence of such programs on those students facilitating the informal science programs. Through Partnerships for Informal Science Education in the Community (PISEC) at the University of Colorado Boulder, undergraduate and graduate physics students coach elementary and middle school children during an inquiry-based science afterschool program. As part of their participation in PISEC, university students complete preparation in pedagogy, communication and diversity, engage with children on a weekly basis and provide regular feedback about the program. We present findings that indicate these experiences improve the ability of university students to communicate in everyday language and positively influence their perspectives on teaching and learning.

    2015-01-01

    The human mind is endowed with innate primordial perceptions such as space, distance, motion, change, flow of time, matter. The field of cognitive science argues that the abstract concepts of mathematics are not Platonic, but are built in the brain from these primordial perceptions, using what are known as conceptual metaphors. Known cognitive mechanisms give rise to the extremely precise and logical language of mathematics. Thus all of the vastness of mathematics, with its beautiful theorems, is human mathematics. It resides in the mind, and is not `out there'. Physics is an experimental science in which results of experiments are described in terms of concrete concepts - these concepts are also built from our primordial perceptions. The goal of theoretical physics is to describe the experimentally observed regularity of the physical world in an unambiguous, precise and logical manner. To do so, the brain resorts to the well-defined abstract concepts which the mind has metaphored from our primordial percepti...

    As of 2010, less than 10% of the members of the APS division of plasma physics are female. Data from a 2005 AIP publication indicate that a lack of female presence in physics exists as early as high school and is perpetuated throughout the educational careers of women. Of the undergraduate programs run by PPPL, 16% of participants are female, and only 11% of participants that continue on to graduate school are female. In an effort to increase the exposure of young women to physics, we have expanded existing programs and initiated new programs such as a mentorship program and an energy focused essay contest. The goal of these programs is to bridge the gap between young and established women in science in order to increase young women's interest in the field of physics and thus increase the likelihood that they will continue on to study higher-level physics. Using data collected from participant surveys we have assessed the short-term effectiveness of PPPL programs in influencing young women to pursue careers in science and plasma physics. Ivie and Ray.

    National studies conducted over many years show that, while most Americans are interested in science and support federal funding of scientific research, the scientific literacy of the public is very low. Why this situation exists and who is responsible are not easy questions to answer. This paper describes a project aimed at addressing that problem, at least among college students, by re-designing the general education physical science course, common in most colleges and universities, to teach basic physics principles via the physics found in films, particularly the action films popular among today's students. Results of the first year's trial of the `Physics in Films' approach are more than promising, they may be pointing the way to the solution of the problem.

    2015-01-01

    Improvements in performance and approval obtained by first year engineering students from University of Concepcion, Chile, were studied, once a virtual didactic model of multiple-choice exam, was implemented. This virtual learning resource was implemented in the Web ARCO platform and allows training, by facing test models comparable in both time and difficulty to those that they will have to solve during the course. It also provides a feedback mechanism for both: 1) The students, since they can verify the level of their knowledge. Once they have finished the simulations, they can access a complete problem-solving heuristic report of each problem; 2) The teachers, since they can obtain information about the habits of the students in their strategies of preparation; and they also can diagnose the weaknesses of the students prior to the exam. This study indicates how this kind of preparation generates substantial improvements on the approval rates by allowing the students: 1) A more structured and oriented syste...

  10. A univariate analysis of variance design for multiple-choice feeding-preference experiments: A hypothetical example with fruit-eating birds

    NASA Astrophysics Data System (ADS)

    Larrinaga, Asier R.

    2010-01-01

    I consider statistical problems in the analysis of multiple-choice food-preference experiments, and propose a univariate analysis of variance design for experiments of this type. I present an example experimental design, for a hypothetical comparison of fruit colour preferences between two frugivorous bird species. In each fictitious trial, four trays each containing a known weight of artificial fruits (red, blue, black, or green) are introduced into the cage, while four equivalent trays are left outside the cage, to control for tray weight loss due to other factors (notably desiccation). The proposed univariate approach allows data from such designs to be analysed with adequate power and no major violations of statistical assumptions. Nevertheless, there is no single "best" approach for experiments of this type: the best analysis in each case will depend on the particular aims and nature of the experiments.

    2002-04-01

    This article describes the development and application of a two-tier multiple choice diagnostic instrument to assess high school students' understanding of inorganic chemistry qualitative analysis. The development of the diagnostic instrument was guided by the framework outlined by Treagust. The instrument was administered to 915 Grade 10 students (15 to 17 years old) from 11 schools after they had learned the theory involved in qualitative analysis and after a series of qualitative analysis practical sessions. The Cronbach alpha reliability of the instrument was .68, the facility indices ranged from .17 to .48, and the discrimination indices ranged from .20 to .53. The study showed that the Grade 10 students had difficulty understanding the reactions involved in the identification of cations and anions, for example, double decomposition reactions, the formation and reaction of complex salts, and thermal decomposition. The findings of the study and literature on practical work were used to develop a qualitative analysis teaching package.

  17. Physics teacher use of the history of science

    NASA Astrophysics Data System (ADS)

    Winrich, Charles

    The School of Education and the Department of Physics at Boston University offer a sequence of 10 two-credit professional development courses through the Improving the Teaching of Physics (ITOP) project. The ITOP courses combine physics content, readings from the physics education research (PER) literature, and the conceptual history of physics (CHOP). ITOP participants self-report changes to their teaching practices as a result of their participation in ITOP. The purpose of this study was to verify and characterize those changes in the specific area of the participants' use of history after their study of CHOP. Ten recent ITOP participants were observed, interviewed, and asked to provide lesson plans and samples of student work from their classes. Case studies of each participant's teaching were constructed from the data. The individual cases were synthesized to characterize the impact of CHOP on the ITOP participants. The results show that the participants integrate CHOP into their pedagogical content knowledge (PCK) to inform their understanding of: (1) the relationship between physics and other disciplines, (2) the relationship between specific physics concepts, (3) student understanding of physics concepts, (4) student difficulties in learning physics concepts, and (5) methods for teaching physics concepts. The participants use history to teach a variety of topics, although the most common were mechanics and electromagnetism. All of the participants used history to teach aspects of the nature of science (NOS) and to increase student interest in physics, while eight participants taught physics concepts through history. The predominant mode of incorporating history was through adding anecdotes about the scientists who worked on the concepts, but seven participants had their students study the historical development of physical concepts. All the participants discussed a lack of time as a factor that inhibits a greater use of history in their courses. Eight participants discussed a lack of appropriate resources for using history in high school physics classes. Two participants said they did not feel that explicit study of the history of physics would benefit their students until they had better mastery of physics concepts.

  18. Developing the learning physical science curriculum: Adapting a small enrollment, laboratory and discussion based physical science course for large enrollments

    2012-06-01

    We report on the adaptation of the small enrollment, lab and discussion based physical science course, Physical Science and Everyday Thinking (PSET), for a large-enrollment, lecture-style setting. Like PSET, the new Learning Physical Science (LEPS) curriculum was designed around specific principles based on research on learning to meet the needs of nonscience students, especially prospective and practicing elementary and middle school teachers. We describe the structure of the two curricula and the adaptation process, including a detailed comparison of similar activities from the two curricula and a case study of a LEPS classroom implementation. In LEPS, short instructor-guided lessons replace lengthier small group activities, and movies, rather than hands-on investigations, provide the evidence used to support and test ideas. LEPS promotes student peer interaction as an important part of sense making via “clicker” questions, rather than small group and whole class discussions typical of PSET. Examples of student dialog indicate that this format is capable of generating substantive student discussion and successfully enacting the design principles. Field-test data show similar student content learning gains with the two curricula. Nevertheless, because of classroom constraints, some important practices of science that were an integral part of PSET were not included in LEPS.

    Physical Science for Everyday Thinking (PSET) is a guided inquiry approach to teaching physical science. Pre and post survey data were collected during four years of using PSET. The course was taught in an intensive format at a small, private liberal arts college; at least half the students were education majors. The surveys assessed content knowledge and confidence in the answers, attitudes toward science and understanding of the process of learning science. Analysis indicated significant increases in content knowledge, confidence in content knowledge and comfort levels with physical science; also significant changes in identification as a science person, what is a fact, objectivity of scientists and science as a solitary pursuit.

    A modified Delphi Technique was developed to ensure that two textbook chapters written for a future physical science teacher preparation textbook would be consistent with pertinent science teaching and teacher preparation standards, and inclusive of relevant educational research findings. The primary research question of this dissertation was, "How does one develop a valid and reliable framework for reasonably ensuring that textbook chapters are congruent with stated expectations?" During this investigation the researcher independently developed two textbook chapters, and used the modified Delphi Technique to consult content-area experts to determine the congruence of the new textbook chapters with stated expectations.

    The Church-Turing thesis is one of the pillars of computer science; it postulates that every classical system has equivalent computability power to the so-called Turing machine. While this thesis is crucial for our understanding of computing devices, its implications in other scientific fields have hardly been explored. Here we start this research programme in the context of quantum physics and show that computer science laws have profound implications for some of the most fundamental results of the theory. We first show how they question our knowledge on what a mixed quantum state is, as we identify situations in which ensembles of quantum states defining the same mixed state, indistinguishable according to the quantum postulates, do become distinguishable when prepared by a computer. We also show a new loophole for Bell-like experiments: if some of the parties in a Bell-like experiment use a computer to decide which measurements to make, then the computational resources of an eavesdropper have to be limited in order to have a proper observation of non-locality. Our work opens a new direction in the search for a framework unifying computer science and quantum physics.

    Much remains to be done to improve education and scientific research in Africa. Supported by the international scientific community, our initiative has been to contribute to fostering science in sub-Saharan Africa by establishing a biennial school on fundamental subatomic physics and its applications. The school is based on a close interplay between theoretical, experimental, and applied physics. The lectures are addressed to students or young researchers with at least a background of 4 years of university formation. The aim of the school is to develop capacity, interpret, and capitalize on the results of current and future physics experiments with particle accelerators; thereby spreading education for innovation in related applications and technologies, such as medicine and information science. Following the worldwide success of the first school edition, which gathered 65 students for 3-week in Stellenbosch (South Africa) in August 2010, the second edition will be hosted in Ghana from July 15 to August 4, 2012. The school is a non-profit organization, which provides partial or full financial support to 50 of the selected students, with priority to Sub-Saharan African students.

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

    NASA Astrophysics Data System (ADS)

    van den Berg, G. P.

    1998-03-01

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

  17. Invisible World and Modern Physics: Modern Science and Theology

    NASA Astrophysics Data System (ADS)

    Theodossiou, E.; Manimanis, V. N.; Danezis, E.

    2010-07-01

    A characteristic of the Western thought is the effort to counter Christian theology through arguments based on scientific discoveries (antirrhetic theology). Two objections can be raised against this trait: a) Modern science considers as a fact the future expansions, corrections, even total abolishment of scientific knowledge in the face of new discoveries. Therefore, dogmatic positions must not be based on temporary scientific views. b) Antirrhetic theology is mostly based on out-of-date scientific views of the period 1650-1900, which are not valid any more. The example of modern physics and cosmology is prime among them; in these sciences, the prevailing theories are based on the existence of an imperceptible reality, or on apparently “illogical” (in the sense of classical logic) fundamental properties of matter and its particles in quantum mechanics.

The leading term in the series is the Bethe-Peierls (belief propagation) (BP) contribution; the rest are expressed as loop contributions on the factor graph and calculated directly using the BP solution. The series unveils a small parameter that often makes the BP approximation so successful. Applications of the loop calculus in statistical physics and information science are discussed.

    Numeroso, Filippo; Benatti, Mario; Pizzigoni, Caterina; Sartori, Elisabetta; Lippi, Giuseppe; Cervellin, Gianfranco

    2015-01-01

    BACKGROUND: A poor communication with immigrants can lead to inappropriate use of healthcare services, greater risk of misdiagnosis, and lower compliance with treatment. As precise information about communication between emergency physicians (EPs) and immigrants is lacking, we analyzed difficulties in communicating with immigrants in the emergency department (ED) and their possible associations with demographic data, geographical origin and clinical characteristics. METHODS: In an ED with approximately 85 000 visits per year, a multiple-choice questionnaire was given to the EPs 4 months after discharge of each immigrant in 2011. RESULTS: Linguistic comprehension was optimal or partial in the majority of patients. Significant barriers were noted in nearly one fourth of patients, for only half of them compatriots who were able to translate. Linguistic barriers were mainly found in older and sicker patients; they were also frequently seen in patients coming from western Africa and southern Europe. Non-linguistic barriers were perceived by EPs in a minority of patients, more frequently in the elderly and frequent attenders. Factors independently associated with a poor final comprehension led to linguistic barriers, non-linguistic obstacles, the absence of intermediaries, and the presence of patient’s fear and hostility. The latter probably is a consequence, not the cause, of a poor comprehension. CONCLUSION: Linguistic and non-linguistic barriers, although quite infrequent, are the main factors that compromise communication with immigrants in the ED, with negative effects especially on elderly and more seriously ill patients as well as on physician satisfaction and appropriateness in using services.

    An individual's motivational orientation serves as a drive to action and can influence their productivity. This study examines how the goal orientation of students towards the pursuit of their graduate degree in physics and chemistry influences their future success outcomes as practicing scientists. Two main orientations are focused on: performance (or ego/ability) orientation and learning (or task/mastery) orientation. The data was obtained as part of Project Crossover, which applied a mixed methodological approach to studying the transition from graduate student to scientist in the physical sciences. Using regression analysis on survey data from 2353 PhD holders in physics and chemistry, we found that individuals exhibiting a learning orientation were more productive than those exhibiting a performance orientation in terms of first-author publications and grant funding. Furthermore, given equal salary, learning-oriented physical scientists produced more first-author publications than average. )

    2012-02-01

    This study investigates the gaze patterns of undergraduate college students attending a lecture-based physical science class to better understand the relationships between gaze and focus patterns and student attention during class. The investigators used a new eye-tracking product; Tobii Glasses. The glasses eliminate the need for subjects to focus on a computer screen or carry around a backpack-sized recording device, thus giving an investigator the ability to study a broader range of research questions. This investigation includes what students focus on in the classroom (i.e. demonstrations, instructor, notes, board work, and presentations) during a normal lecture, what diverts attention away from being on task as well as what keeps a subject on task. We report on the findings from 8 subjects during physical science lectures designed for future elementary school teachers. We found that students tended not to focus on the instructor for most parts of the lecture but rather the information, particularly new information presented on PowerPoint slides. Finally, we found that location in the classroom also impacted students' attention spans due to more distractors.

  19. The Persistent Dearth of Women in the Physical Sciences

    2002-04-01

    For twenty years, scientists and society alike have averred that discrimination against women is a thing of the past, which may be largely true for the most overt kind of discrimination. Yet judging from the scarcity of women in the physical sciences in the U.S. today, it is clear that these professions efficiently filter out women (and probably other minorities). Not only are women present in much smaller numbers than men at all levels, their presence decreases with increasing rank in the academic hierarchy, and women advance more slowly and with greater attrition than men. Notably, the pre-college pipeline is no longer the critical issue, since women are present in large numbers in introductory science and math classes at top undergraduate institutions. However, there is little agreement on what the critical problem might be, much less its solution. Furthermore, most physical scientists in academia, which is to say male full professors, have paid relatively little attention to this problem and are not well informed about the current status of women in their fields or the extensive research on gender bias. I review the relevant statistics and some of this research. I conclude that progress is possible if people in positions of power adopt the inclusion of women as a priority. This will enhance excellence in our profession, both because it taps a wider pool of talent and because it corrects the bias that has (under the assumption of equal distribution of talent among men and women) excluded some of our best scientists.

  20. Physics and social science — The approach of synergetics

    NASA Astrophysics Data System (ADS)

    Weidlich, Wolfgang

    1991-05-01

    Universally applicable methods originating in statistical physics and synergetics are combined with concepts from social science in order to set up and to apply a model construction concept for the quantitative description of a broad class of collective dynamical phenomena within society. Starting from the decisions of individuals and introducing the concept of dynamical utilities, probabilistic transition rates between attitudes and actions can be constructed. The latter enter the central equation of motion, i.e. the master equation, for the probability distribution over the possible macroconfigurations of society. From the master equation the equations of motion for the expectation values of the macrovariables of society can be derived. These equations are in general nonlinear. Their solutions may include stationary solutions, limit cycles and strange attractors, and with varying trend parameters also phase transitions between different modes of social behaviour can be described. The general model construction approach is subsequently applied to characteristic examples from different social sciences, such as sociology, demography, regional science and economics. These examples refer to collective political opinion formation, to interregional migration of interactive populations, to settlement formation on the micro-, meso- and macroscale, and to nonlinear nonequilibrium economics, including market instabilities.

    Contemporary physical science studies rely on the effective analyses of geographically dispersed spatial data and simulations of physical phenomena. Single computers and generic high-end computing are not sufficient to process the data for complex physical science analysis and simulations, which can be successfully supported only through distributed computing, best optimized through the application of spatial principles. Spatial computing, the computing aspect of a spatial cyberinfrastructure, refers to a computing paradigm that utilizes spatial principles to optimize distributed computers to catalyze advancements in the physical sciences. Spatial principles govern the interactions between scientific parameters across space and time by providing the spatial connections and constraints to drive the progression of the phenomena. Therefore, spatial computing studies could better position us to leverage spatial principles in simulating physical phenomena and, by extension, advance the physical sciences. Using geospatial science as an example, this paper illustrates through three research examples how spatial computing could (i) enable data intensive science with efficient data/services search, access, and utilization, (ii) facilitate physical science studies with enabling high-performance computing capabilities, and (iii) empower scientists with multidimensional visualization tools to understand observations and simulations. The research examples demonstrate that spatial computing is of critical importance to design computing methods to catalyze physical science studies with better data access, phenomena simulation, and analytical visualization. We envision that spatial computing will become a core technology that drives fundamental physical science advancements in the 21st century. PMID:21444779

    Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

  16. The material co-construction of hard science fiction and physics

    NASA Astrophysics Data System (ADS)

    Hasse, Cathrine

    2014-02-01

    This article explores the relationship between hard science fiction and physics and a gendered culture of science. Empirical studies indicate that science fiction references might spur some students' interest in physics and help develop this interest throughout school, into a university education and even further later inspire the practice of doing science. There are many kinds of fiction within the science fiction genre. In the presented empirical exploration physics students seem particularly fond of what is called `hard science fiction': a particular type of science fiction dealing with technological developments (Hartwell and Cramer in The hard SF renaissance, Orb/TOR, New York, 2002). Especially hard science fiction as a motivating fantasy may, however, also come with a gender bias. The locally materialized techno-fantasies spurring dreams of the terraforming of planets like Mars and travels in time and space may not be shared by all physics students. Especially female students express a need for other concerns in science. The entanglement of physics with hard science fiction may thus help develop some students' interest in learning school physics and help create an interest for studying physics at university level. But research indicates that especially female students are not captured by the hard techno-fantasies to the same extent as some of their male colleagues. Other visions (e.g. inspired by soft science fiction) are not materialized as a resource in the local educational culture. It calls for an argument of how teaching science is also teaching cultural values, ethics and concerns, which may be gendered. Teaching materials, like the use of hard science fiction in education, may not just be (yet another) gender bias in science education but also carrier of particular visions for scientific endeavours.

  20. Physics First: Impact of course sequencing on the attitudes of female students toward science

    NASA Astrophysics Data System (ADS)

    O'Connor, Linda Miller

    This study was causal-comparative research to determine if there is any relationship between course sequencing and female students' attitudes toward science and their intent to participate in advanced level science courses or pursue science related careers. Physics First promotes the reversal of the traditional sequencing of high school science courses (biology, chemistry and physics) to physics, chemistry and biology or a two or three year integrated European science approach. Physics as a first year high school course of study necessitates changing the course approach to a more conceptual approach and less mathematical and theoretical. Eleventh grade students from two suburban Chicago high schools comprised the sample. The two schools were judged to be extremely similar in their demographic make-up as reported in the 2002 Illinois School Report Card. The notable difference between the schools being the science course sequence recommended for average and above average students. The sample responded to a scanable questionnaire consisting of demographic data and the Test of Science Related Attitudes (TOSRA). TOSRA is a seventy item Likert Scale instrument that addresses attitudes in seven domains; social implications of science, normality of scientists, attitude toward inquiry, adoption of scientific attitudes, enjoyment of science lessons, leisure interest in science, and career interest in science. Values from 1-50 are obtained for each domain with no overall attitude value assigned. The research found that girls in general had significantly more positive attitudes toward science in all seven of the measured domains and the females from the traditional approach were more positive than the females from the Physics First approach. Girls from the traditional approach also reported intent to take high-level (AP) science courses in their senior year at a significantly higher rate than did the girls in Physics First. Neither science approach showed any significance in the reported intention to pursue a science-related career.

  8. Sex, Class, and Physical Science Educational Attainment: Portions due to Achievement Versus Recruitment

    NASA Astrophysics Data System (ADS)

    Simon, Richard M.; Farkas, George

    Nationally representative data from the National Education Longitudinal Study are used to investigate why males (rather than females) and children of parents with advanced degrees (rather than those from less-educated parents) are more highly represented among physical science bachelor's degrees and graduate students. Parental education is measured by three categories: neither parent has a bachelor's degree, at least one parent has a bachelor's degree, or at least one parent has a degree beyond the bachelor's. Physical science is defined as students majoring in physics, engineering, mathematics, or computer science. The effects of mathematics achievement and effects not accounted for by mathematics achievement (what the authors call "recruitment" effects) are isolated for parental education categories and for sex, allowing inequality in physical science degree attainment to be decomposed into portions due to achievement and portions due to recruitment. Additionally, the results from logistic regressions predicting the attainment of a bachelor's degree in physical science as well as the pursuit of a graduate degree in physical science are presented. It is found that for parental education categories, the gaps in physical science educational attainment are nearly entirely accounted for by differences in mathematics achievement, suggesting that if achievement could be equalized, physical science educational attainment differences among parental education categories would disappear. However, the sex gap in physical science educational attainment operates almost entirely independent of achievement effects, suggesting that if the mathematics achievement distributions of males and females were identical, the sex gap in physical science educational attainment would be unchanged from what it is today.

    The Space Physics community has developed a number of activities, curricula, and outreach efforts for K-12 classrooms. In order for these efforts to be adopted in the classroom, they must be accompanied by professional development opportunities and directly address the state science standards. This paper presents the results of a survey of the California and National Science Standards that are directly applicable to solar, heliospheric, magnetospheric and ionospheric physics. The results have been compiled on a website to allow Space Physics EPO curriculum and activity designers to easily reference the specific content standards. Examples of Space Physics "hooks" are also provided to demonstrate how our science can help motivate space and physics concepts in the classroom.

  11. Paradoxical effects of injection stress and nicotine exposure experienced during adolescence on learning in a serial multiple choice (SMC) task in adult female rats.

    PubMed

    Renaud, Samantha M; Pickens, Laura R G; Fountain, Stephen B

    2015-01-01

    Nicotine exposure in adolescent rats has been shown to cause learning impairments that persist into adulthood long after nicotine exposure has ended. This study was designed to assess the extent to which the effects of adolescent nicotine exposure on learning in adulthood can be accounted for by adolescent injection stress experienced concurrently with adolescent nicotine exposure. Female rats received either 0.033 mg/h nicotine (expressed as the weight of the free base) or bacteriostatic water vehicle by osmotic pump infusion on postnatal days 25-53 (P25-53). Half of the nicotine-exposed rats and half of the vehicle rats also received twice-daily injection stress consisting of intraperitoneal saline injections on P26-53. Together these procedures produced 4 groups: No Nicotine/No Stress, Nicotine/No Stress, No Nicotine/Stress, and Nicotine/Stress. On P65-99, rats were trained to perform a structurally complex 24-element serial pattern of responses in the serial multiple choice (SMC) task. Four general results were obtained in the current study. First, learning for within-chunk elements was not affected by either adolescent nicotine exposure, consistent with past work (Pickens, Rowan, Bevins, and Fountain, 2013), or adolescent injection stress. Thus, there were no effects of adolescent nicotine exposure or injection stress on adult within-chunk learning typically attributed to rule learning in the SMC task. Second, adolescent injection stress alone (i.e., without concurrent nicotine exposure) caused transient but significant facilitation of adult learning restricted to a single element of the 24-element pattern, namely, the "violation element," that was the only element of the pattern that was inconsistent with pattern structure. Thus, adolescent injection stress alone facilitated violation element acquisition in adulthood. Third, also consistent with past work (Pickens et al., 2013), adolescent nicotine exposure, in this case both with and without adolescent injection stress, caused a learning impairment in adulthood for the violation element in female rats. Thus, adolescent nicotine impaired adult violation element learning typically attributed to multiple-item learning in the SMC task. Fourth, a paradoxical interaction of injection stress and nicotine exposure in acquisition was observed. In the same female rats in which violation-element learning was impaired by adolescent nicotine exposure, adolescent nicotine experienced without adolescent injection stress produced better learning for chunk-boundary elements in adulthood compared to all other conditions. Thus, adolescent nicotine without concurrent injection stress facilitated adult chunk-boundary element learning typically attributed to concurrent stimulus-response discrimination learning and serial-position learning in the SMC task. To the best of our knowledge, the current study is the first to demonstrate facilitation of adult learning caused by adolescent nicotine exposure. PMID:25527003

  14. The nature of science and Physics First: Does course sequence influence students' perceptions of nature of science?

    NASA Astrophysics Data System (ADS)

    Neufell, James V., Jr.

    The purpose of this study was to assemble an empirical data set that describes the impact of the Physics First curriculum sequence from the perspective of students' perceptions of nature of science (NOS). Specifically, this study examined two schools, one where Physics First is used and the other where a more traditional science sequence is utilized. Mixed-methods research was employed; therefore, both quantitative and qualitative data inform the study. The results indicate that students who have completed the Physics First sequence do not demonstrate a better understanding of nature of science (NOS) than their counterparts who have completed a more traditional science sequence. The data collected in this study does not support a more refined scientific worldview; a better understanding of the nature of scientific inquiry; or a better understanding of the scientific enterprise by Physics First students. Finally, the evidence collected in this study suggests a 'static' NOS epistemological development between 9th and 11th grade by students in both the Physics First and traditional science sequences. Implications for instruction and recommendations for future research are also discussed.

    NASA Astrophysics Data System (ADS)

    Dabney, Katherine Patricia Traudel

    Science, technology, engineering, and mathematics (STEM) education has become a critical focus in the United States due to economic concerns and public policy (National Academy of Sciences, 2007; U.S. Department of Education, 2006). Part of this focus has been an emphasis on encouraging and evaluating career choice and persistence factors among underrepresented groups such as females in the physical sciences (Hill et al., 2010; National Academy of Sciences, 2007). The majority of existing STEM research studies compare women to men, yet a paucity of research exists that examines what differentiates female career choice within the physical sciences. In light of these research trends and recommendations, this study examines the following questions: 1. On average, do females who select chemistry or physics doctoral programs differ in their reported personal motivations and background factors prior to entering the field? 2. Do such variables as racial and ethnic background, age, highest level of education completed by guardians/parents, citizenship status, family interest in science, first interest in general science, first interest in the physical sciences, average grades in high school and undergraduate studies in the physical sciences, and experiences in undergraduate physical science courses explain a significant amount of variance in female physical scientists' years to Ph.D. completion? These questions are analyzed using variables from the Project Crossover Survey dataset through a subset of female physical science doctoral students and scientists. Logistic regression analyses are performed to uncover what differentiates women in the physical sciences based on their background, interest, academic achievement, and experiences ranging prior to elementary school through postsecondary education. Significant variables that positively predict a career choice in chemistry or physics include content specific high school and undergraduate academic achievement and positive undergraduate experiences. Two multiple regression models, one composed of female chemists and one of female physicists, examine significant predictors that positively associated with time to doctoral degree completion. The models account for little differentiation in the outcome of time to doctoral completion. In addition, significant predictors are based on demographic and achievement factors that were not paralleled in the two multiple regressions.

  18. What do seniors remember from freshman physics?

    NASA Astrophysics Data System (ADS)

    2012-12-01

    We have given a group of 56 Massachusetts Institute of Technology (MIT) seniors who took mechanics as freshmen a written test similar to the final exam they took in their freshman course as well as the Mechanics Baseline Test (MBT) and the Colorado Learning Attitudes about Science Survey (CLASS). Students in majors unrelated to physics scored 60% lower on the written analytic part of the final than they would have as freshmen. The mean score of all participants on the MBT was insignificantly changed from their average on the posttest they took as freshmen. However, the students’ performance on 9 of the 26 MBT items (with 6 of the 9 involving graphical kinematics) represents a gain over their freshman posttest score (a normalized gain of about 70%), while their performance on the remaining 17 questions is best characterized as a loss of approximately 50% of the material learned in the freshman course. On multiple-choice questions covering advanced physics concepts, the mean score of the participants was about 50% lower than the average performance of freshmen. Although attitudinal survey results indicate that almost half the seniors feel the specific mechanics course content is unlikely to be useful to them, a significant majority (75%-85%) feel that physics does teach valuable problem solving skills, and an overwhelming majority believe that mechanics should remain a required course at MIT.
