This article provides an extended, comprehensive example of how teachers, schools, districts, and external factors (e.g., parental pressure and policy mandates) shape curriculum research in the U.S. It retrospectively examines how three different middle school curriculum units were implemented and scaled‐up in a large, diverse school system. The curriculum materials were cognitively based, hands‐on, guided inquiry units; each focused on a different “big idea” in science. The units met some criteria for instructional strategies rated by the Project 2061 Curriculum Analysis. Using evidence‐based decisions, two of the units were found to be effective and equitable, and went to scale, but one was not effective. However, the course of scale‐up was also affected by a changing policy climate, and proceeded in unpredictable ways, with small scale effects not found at large scale, and experienced teachers less effective than inexperienced teachers. Four years after funding ended, none of the units were sustained within the school district. The interactions between the demands of the units and of the school district's policy environment suggests reasons why this occurred, despite evidence that two of the units were successful with diverse learners. © 2012 Wiley Periodicals, Inc.

This study uses household survey data to estimate determinants of schooling in Uganda, with a model that includes the price of school. Uganda's universal education policy offered free tuition, fees, and supplies to up to four children per family, including two daughters. The empirical method includes an estimation of a child-specific price of schooling. Despite widespread subsidies, the cost of primary school remained an obstacle under this policy, but the effects of price were similar for boys and girls. Regressions by wealth quintile estimate nonlinear effects of wealth and price, suggesting that there are opportunities to expand education through targeted cash transfer and subsidy policies.  相似文献

This study examined whether the longitudinal links between mothers' use of spanking and children's externalizing behaviors are moderated by family race/ethnicity, as would be predicted by cultural normativeness theory, once mean differences in frequency of use are controlled. A nationally representative sample of White, Black, Hispanic, and Asian American families (n = 11,044) was used to test a cross-lagged path model from 5 to 8 years old. While race/ethnic differences were observed in the frequency of spanking, no differences were found in the associations of spanking and externalizing over time: Early spanking predicted increases in children's externalizing while early child externalizing elicited more spanking over time across all race/ethnic groups.  相似文献

Information and information technology developments are influencing the economies of many countries. Information needs to be made available and accessible in countries for industrial, educational and governmental purposes. Information is also an asset of unpredictable value. For these reasons, governments should acknowledge and value the relevance of such information, and therefore address it through national policies. Many countries have developed national information policies which reflect the values that governments attach to the access to and the availability of information in their countries. The most important influences on the development of a national information policy are based on the country's socio-political circumstances. Developing countries are advised to focus attention in their national information policies on aspects concerning socio-economic development, the application of information and access to information.  相似文献

As reference work changes dramatically due to computer technology, tangible reference collections are disappearing from academic libraries in many fields. Such is not the case in music research libraries, however. While many important online music reference resources exist, many print resources remain vitally important, and because of limited funding, they are unlikely to be digitized soon. Music libraries and music reference collections are currently a combination of traditional and online resources, enhanced by human expertise. This beneficial combination should be maintained.  相似文献

The contemporary interest in researching student agency in science education reflects concerns about the relevance of schooling and a shift in science education towards understanding learning in science as a complex social activity. The purpose of this article is to identify problems confronting the science education community in the development of this new research agenda and to argue that there is a need for research in science education that attends to agency as a social practice. Despite increasing interest in student agency in educational research, the term ‘agency’ has lacked explicit operationalisation and, across the varied approaches, such as critical ethnography, ethnographies of communication, discourse analysis and symbolic interactionism, there has been a lack of coherence in its research usage. There has also been argument concerning the validity of the use of the term ‘agency’ in science education research. This article attempts to structure the variety of definitions of ‘student agency’ in science education research, identifies problems in the research related to assigning intentionality to research participants and argues that agency is a kind of discursive practice. The article also draws attention to the need for researchers to be explicit in the assumptions they rely upon in their interpretations of social worlds. Drawing upon the discursive turn in the social sciences, a definition of agency is provided, that accommodates the discursive practices of both individuals and the various functional social groups from whose activities classroom practice is constituted. The article contributes to building a focused research agenda concerned with understanding and promoting student agency in science.  相似文献

The purpose of this article is to illustrate Professor William L. Boyd's insights into the political ecology of schooling and his contributions and collaboration with others concerned about ensuring the well-being of students, families, and communities. Over his career, Boyd investigated the subtle and complex organizational constraints to school-linked coordinated services, including examining the reasons for the unrelenting resistance of public organizations to change, despite repeated efforts to reform them. We trace the history of the community schools movement and explore the influential, and at times prophetic, scholarly contributions of William L. Boyd to the research and discussion on the effectiveness, challenges, and future promise of this reform strategy. We hope that current and future researchers can learn from and build on his scholarship to develop new pathways to improve the lives of at-risk children.  相似文献
