This study investigated the understanding of science process skills (SPS) of 329 science teachers from 52 primary schools selected by random sampling. The understanding of SPS was measured in terms of conceptual and operational aspects of SPS using an instrument called the Science Process Skills Questionnaire (SPSQ) with a Cronbach’s alpha reliability of 0.88. The findings showed that the teachers’ conceptual understanding of SPS was much weaker than their practical application of SPS. The teachers’ understanding of SPS differed by their teaching qualifications but not so much by their teaching experience. Emphasis needs to be given to both conceptual and operational understanding of SPS during pre-service and in-service teacher education to enable science teachers to use the skills and implement inquiry-based lessons in schools. 相似文献

The authors model the class size and teaching load decisions of academic departments in terms of a departmental utility function. Utility is postulated to be asymmetric around class size and teaching load norms, and variables for curricular structure, disciplinary domain, and institutional type are taken into account. Maximization of the utility function produces decision rules for the number of sections to be offered for each course, and hence the faculty's overall teaching load. A nonlinear estimator is developed for the decision rules' parameters and applied to data from four liberal arts colleges and two research universities. Results are consistent with theories about faculty discretionary time and with expectations about the effects of curricular structure on class size. The paper concludes with a discussion about the effects of enrollment uncertainty on faculty load decisions. 相似文献

This study addresses the health of young children and how to safely and effectively care for children with diarrhea in the home and in early child care settings. A baseline survey showed the prevalence of oral rehydration solution (ORS) usage at last diarrhea bout to be low. An educational workshop was developed to train parents and child care professionals on how to properly manage young children with diarrhea and reduce the risk of diarrhea spread at home and in early childhood settings. Specific intervention activities are discussed and program activities, including specially designed materials for mixing homemade ORS are described. A comparison of pre- and postintervention data indicates substantial gains in knowledge among both urban and rural populations. Implications of research findings are discussed along with suggestions for future research. 相似文献

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved. 相似文献

Given the importance of developing civically engaged and knowledgeable citizens, many have sought to improve the quality of students’ civic education experiences. This article examines one particular effort spearheaded by the Joe Foss Institute, the Civic Education Initiative (CEI). Since the CEI was announced, 18 states have passed legislation that includes a civics test component embedded in the CEI. This conceptual article examines the CEI against research-based practices for teaching civics. It then introduces the policy design framework as a tool for analyzing civic policies like CEI. This political science theory recognizes that policies themselves send important signals that have implications for students’ civic development. We utilize the policy design framework to analyze CEI and, in particular, how CEI is likely to shape students’ civic and political engagement. We conclude with a proposal for future research on civic education using the policy design framework. 相似文献
