Homework gives students an opportunity to practice important college‐level physics skills. A switch to Web‐based homework alters the nature of feedback received, potentially changing the pedagogical benefit. Calculus‐ and algebra‐based introductory physics students enrolled in large paired lecture sections at a public university completed homework of standard end‐of‐the‐chapter exercises using either the Web or paper. Comparison of their performances on regular exams, conceptual exams, quizzes, laboratory, and homework showed no significant differences between groups; other measures were found to be strong predictors of performance. This indicates that the change in medium itself has limited effect on student learning. Ways in which Web‐based homework could enable exercises with greater pedagogical value are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 1050–1071, 2003 相似文献

ABSTRACTAdolescent sexual health programs often frame needs assessments using risk-taking, disease, or fertility data, fostering a narrow perspective of sexual health and limiting scopes of related programs. We address the gap between traditional measures and the socioecological lens used by many in the field. Using Washington State as an example, we report methods for developing and mapping an index of sex education needs that integrates social determinants of health (SDH) to reflect the complex, interrelated influences affecting adolescents. The generated index and maps support a holistic approach to assessing inequity, resource allocation gaps, and specific programmatic needs of young people. This case study demonstrates that it is possible and important to align adolescent sexual health measurement strategies with more holistic adolescent sexuality development frameworks. We recommend that public health professionals consider a broader range of data on SDH in their sex education policy and program decision making. 相似文献

The design and evaluation of the New England Head Start Teaching Center (NEHSTC), one of 14 federally funded programs created to test the efficacy of participatory, hands-on training for enhancing Head Start service delivery is the focus of this article. The unique characteristics of the NEHSTC and the outcome evaluation results from 3 years of training will be discussed. The findings demonstrate the NEHSTC was successful in implementing high quality, participatory training within the context of an ongoing Head Start program. Various Head Start staff who participated in the NEHSTC trainings demonstrated gains in knowledge, skills, and attitudes compared to similar Head Start employees who did not receive training. The positive findings suggest that participatory training should be included in the menu of training options available. Because of the unique size and scope of Head Start, the success of ongoing efforts to improve the quality of its programs and services are particularly significant. Within Head Start, this discussion of quality enhancements via innovative training models is timely given the advent of the new performance standards and the restructuring of the Training and Technical Assistance system. Additionally, the findings are relevant for broader efforts to improve early care and education programs nationwide. 相似文献

Head Start Teaching Centers are a national demonstration project designed to provide participatory training in all Head Start component areas within the context of an exemplary Head Start program. Each Teaching Center employs an independent evaluation to study this alternative approach to Head Start staff development. This paper presents the results of the outcome evaluation for the first year of the New England Head Start Teaching Center. The New England Head Start Teaching Center was designed to provide intensive training during a 3 or 5 day period of residence at the Teaching Center. This paper briefly describes the national Head Start Teaching Center model, the implementation of this model in the New England region, the outcome evaluation plan, and the results from the first year of training. The analyses of year one data indicated that training provided by the New England Head Start Teaching Center produced significant gains. As compared to similar Head Start employees who did not participate in training, both trainees and their supervisors reported significant gains in trainees' knowledge, skills, and expertise after participating in the New England Head Start Teaching Center training. 相似文献

The paper examines whether intellectual property rights in art should be extended to the entire world. In earlier papers, the economics of patent rights have been examined and the argument made that world welfare is likely to fall if patent rights are extended to the entire world. This argument is recapitulated here with special attention to the assumptions that are needed for its validity. These assumptions are then reexamined in the context of markets for art to see whether the argument carries over. It is found that while most of the assumptions do carry over well enough to justify the argument, there are also certain circumstances that may require greater geographic extension of intellectual property rights in some cases.Paper prepared for a conference on The Economics of Intellectual Property Rights, International Center for Art Economics, University of Venice, October 6–8, 1994. 相似文献

Despite recognition of the importance of a developmentally appropriate approach to sexuality education, there is little direct guidance on how to do this. This study employed in-depth interviews with experienced sexuality educators and developers of sexuality education materials to identify how this concept is understood and applied in the field. Developmentally appropriate sexuality education was conceptualized consistently across interviews to include (a) addressing developmentally relevant topics, (b) adapting content to cognitive development, (c) accommodating developmental diversity, and (d) facilitating the internalization of sexual health messages. However, these views fell short of incorporating the breadth of knowledge offered by adolescent development research. 相似文献

This paper is about a research focusing on recent problems of Hungarian teachers. The aim of the study is to reveal the real troubles of Hungarian pedagogues, on the basis of their answers to a questionnaire, the nature of these problems and how they affect the role of the teacher. Supposedly, the nucleus of the problems of the teachers is connected with existence, skills and material or professional uncertainty. The study based on the related professional literature and its main statements. The conclusions could be applied mostly to the intellectual and existential preparation of would-be teachers. The aim of the research is to reveal the real problems of the high school teachers after the turn of the century, what these problems are, how stressful they are and how they impact the changing teacher role as, ＂Teachers are central to any consideration of schools, and majority of education policy discussions focus directly or indirectly on the role of teachers＂ （Hanushek ＆ Rivkin, 2006）. Ever since the pedagogical researches had started many monitors, surveys and reports have there appeared about the actual matters, issues and problems of the teachers. However, these previous examinations were structured or set up on the base of assumptions of researchers. The possible problem-framing was quite hypothetical and suggested the presuppositions of the inventors of questions, not that of the involved teachers. The methodological mean of the research was the questionnaire. The research has supposed that problems that are in the forefront of teacher thinking include skills, lack of conformity to practical demands, and material and financial uncertainness. We have focused the survey on finding the problematic activities that are primary for the educators. The results could be applied mainly in the field of the teacher training, especially in the mental and existential preparation of the would-be-teachers. It has also an actuality, since the teacher training stands before a changeover from the traditional structure to the two-level structure （transition between the former traditional and the BA and MA levels of higher education）, so these remarks can also add somewhat to the reform program and--at the collective level-to the identification of issues important to the community of teachers, would-be-teachers and both in-service teachers and educators. 相似文献

The use of drawings as representations of personal mental models or images is one method of analyzing personal beliefs. This article discusses the development of the Draw‐An‐Environment Test and Rubric (DAET‐R) for assessing the mental models or images of the environment held by pre‐service teachers. It also provides results of preliminary research using the DAET‐R to assess pre‐service teachers’ personal beliefs and understandings about the environment, as interpreted from their drawings. Results of this pilot study using the DAET‐R for scoring early childhood pre‐service teachers’ drawings of the environment suggest that the participants’ mental models of the environment are incomplete. Results of this study also show that the DAET‐R can provide information about pre‐service teachers’ beliefs about the environment useful to teacher educators in the development and delivery of environmental education. 相似文献
