How can a Website for Physics Teachers Serve as a Tool for Professional Development?     

Esther Bagno  Semadar Levy  Bat-Sheva Eylon 《Journal of Science Education and Technology》2006,15(3-4):215-219

Misconceptions among students studying physics have been widely reported in the research literature. Many teachers are not acquainted with this literature. Moreover, many of them claim that only weak students have misconceptions. This paper reports on an online activity focusing on misconceptions of students regarding Newton’s 3rd Law, that is being carried out through the website of the National Center of Physics Teachers. The aims of the activity are: (1) To convince the teachers that sometimes difficulties in understanding concepts do not stem from the inability of certain students to understand the concept, but rather because of misconceptions in physics. (2) To present the teachers with the findings of studies on physics instruction that deal with the concepts under discussion. (3) To convince the teachers to try out new, innovative teaching strategies.  相似文献   

Reliability of the International Physical Activity Questionnaire in Research Settings: Last 7-Day Self-Administered Long Form     

Susan S. Levy  R. Tucker Readdy 《Measurement in physical education and exercise science》2013,17(4):191-205

This study examined the validity and reliability of decisional balance scales for exercise (i.e., pros and cons) in a large longitudinal population-based randomized sample of Canadian adults ages 18 to 65 years (N = 703). Assessments were taken over 3 time points with 6-month intervals between testing. Content, factorial, concurrent, and construct validity along with internal consistency and test-retest reliability were established for the decisional balance scales. The developed measures have utility for researchers and practitioners who test and apply the exercise decisional balance constructs of the Transtheoretical Model.  相似文献   

The Impact of an Inquiry-Based Geoscience Field Course on Pre-service Teachers     

Gwen Nugent  Michael D. Toland  Richard Levy  Gina Kunz  David Harwood  Denise Green  Kathy Kitts 《Journal of Science Teacher Education》2012,23(5):503-529

The purpose of this quasi-experimental study was to determine the effects of a field-based, inquiry-focused course on pre-service teachers?? geoscience content knowledge, attitude toward science, confidence in teaching science, and inquiry understanding and skills. The field-based course was designed to provide students with opportunities to observe, compare, and investigate geological structures in their natural environment and to gain an understanding of inquiry via hands-on learning activities designed to immerse students in authentic scientific investigation. ANCOVA and MANCOVA analyses examining differences in outcome measures between students in the field experience (n?=?25) and education students enrolled in the traditional, classroom-based course (n?=?37) showed that students in the field course generally had significantly higher scores. Results provide evidence of the value of the field and inquiry-based approach in helping pre-service teachers develop the needed skills and knowledge to create effective inquiry-based science lessons.  相似文献   

A methodological framework for practice-based research in networked learning     

Levy  Philippa 《Instructional Science》2003,31(1-2):87-109

This paper presents a methodological frameworkfor practice-based research in the field ofnetworked learning, based on the author'sapproach to carrying out a case studyevaluation of a networked professionaldevelopment initiative for information servicesstaff in higher education. The theoreticalcase for the framework is made with referenceto principles associated with constructivistprogramme evaluation as well as withinterpretivist and critical traditions inaction research. The purposes and politics ofthis approach, and the question of validationcriteria for claims about its effectiveness forbuilding theory, as well as for evaluating andimproving practice, are discussed. Issues todo with using computer-mediated communicationas a medium for participatory research are alsoraised. An overview is given of the way thisresearch approach was implemented in practice(including the use of a combination of on-lineand face-to-face data collection methods) andsome methodological issues that arose in thecourse of carrying it out are highlighted. Thepaper concludes by suggesting that as amethodology for evaluating, theorising andimproving practice, `networked action research'also offers an approach to pedagogical design,most obviously in the context of networkedprofessional development for educators andlearner support staff.  相似文献

The audience for television news interview programs     

Mark R. Levy 《广播与电子媒介杂志》2013,57(3):339-347

An experiment investigated if graphic censorship disclaimers affect memory or thought elaboration for television news stories of the 1991 Persian Gulf war. Viewer assessment of the credibility of censored news also was considered. Subjects listed their thoughts about each story, and their memory was tested as recognition latency. Subjects who rated the credibility of censored news as moderate scored highest on the memory task, but listed the fewest number of negative mentions about the government named as censor in the stories. Under some conditions, results show that the more viewers thought about the source of the censorship, the lesser they remembered images from the stories.  相似文献   

How Dynamic Visualization Technology can Support Molecular Reasoning   总被引：1，自引：1，他引：0  

Dalit Levy 《Journal of Science Education and Technology》2013,22(5):702-717

This paper reports the results of a study aimed at exploring the advantages of dynamic visualization for the development of better understanding of molecular processes. We designed a technology-enhanced curriculum module in which high school chemistry students conduct virtual experiments with dynamic molecular visualizations of solid, liquid, and gas. They interact with the visualizations and carry out inquiry activities to make and refine connections between observable phenomena and atomic level processes related to phase change. The explanations proposed by 300 pairs of students in response to pre/post-assessment items have been analyzed using a scale for measuring the level of molecular reasoning. Results indicate that from pretest to posttest, students make progress in their level of molecular reasoning and are better able to connect intermolecular forces and phase change in their explanations. The paper presents the results through the lens of improvement patterns and the metaphor of the “ladder of molecular reasoning,” and discusses how this adds to our understanding of the benefits of interacting with dynamic molecular visualizations.  相似文献   

Sample Size Comparisons Involving the Randomized Response Technique     

Kenneth J. Levy 《Journal of Experimental Education》2013,81(1):21-23

The purpose of the present paper is to demonstrate how many more subjects are required to achieve equal power when testing certain hypotheses concerning proportions if the randomized response technique is employed for estimating a population proportion instead of the conventional technique.  相似文献   

Variables that influence the environmental behavior of adults     

Anat Levy  Yossi Leshem 《Environmental Education Research》2018,24(3):307-325

This study focuses on understanding the factors that encourage adults’ environmental behavior. This mixed approach methodology study used 10 Likert type questionnaires to collect data about nine cognitive and affective components that might influence environmental behavior. The qualitative data was collected through open questions and interviews. The main sample included 656 participants from amongst Israel’s working population. The questionnaires were found both reliable and valid. Most of the explored cognitive and affective aspects appeared to act as predictors of environmental behavior. The study indicates that environmental behavior is driven by ‘egoistic’ concerns rather than by altruistic views and motivations.  相似文献   

Global private higher education: an empirical profile of its size and geographical shape     

Daniel C. Levy 《Higher Education》2018,76(4):701-715

Societies’ relative use of private and public services is an abiding and significant issue of scholarly and policy interest. For higher education, however, there has hitherto been no comprehensive dataset and, accordingly, no extensive, reliable analysis of the private-public distribution. As this article provides both the dataset and the analysis, it allows us to discover both the size and geographical shape of global private higher education. Having grown greatly for decades, the private sector now holds a third (32.9%) of the world’s total higher education enrollment. We find striking patterns of concentration and dispersion. The several largest country systems account for much of the private enrollment but, simultaneously, private sectors now exist in all but a few systems; a stunning 97.6% of the world’s present enrollment is in systems with dual-sector provision. Societies no longer rely exclusively on public provision. We discover too that private enrollment concentrates mostly in developing regions, though it is noteworthy in developed regions as well. Asia and Latin America are the twin giants but in all regions, at least 10% of students are in the private sector.  相似文献
