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.

Using Virtual Field Trips to Connect Students with University Scientists: Core Elements and Evaluation of zipTrips? 总被引:1,自引:1,他引:0

Physical field trips to scientists?? work places have been shown to enhance student perceptions of science, scientists and science careers. Although virtual field trips (VFTs) have emerged as viable alternatives (or supplements) to traditional physical fieldtrips, little is known about the potential of virtual field trips to provide the same or similar science career exploration advantages as physical field trips. The overarching goal of this paper is to describe a VFT, zipTrips?, designed to provide middle school students, especially those in resource limited rural areas, with access to university scientists. Using zipTrips as a case example, the paper identifies and describes some of the core characteristics and elements of high quality authentic VFTs that foster student-scientist interactions. In addition, the paper uses program evaluation data to examine the impact of zipTrips on student perceptions of scientists. 相似文献

In this qualitative study we address two primary research questions: What are the experiences of women faculty of color (WFOC) who departed the tenure track at predominantly White, research universities? Using the modified lens of the newcomer adjustment framework, what socialization factors may have contributed to the WFOCs’ departure? Through a longitudinal, in-depth examination of three WFOC who left their university prior to earning tenure, themes of gendered and racialized tokenization and isolation, a need for a more intrusive style of mentoring, and poor institutional fit were identified. Implications for future research on faculty members’ social identity and promising practices for faculty development are shared. 相似文献

There is an increasing expectation that school principals use data to develop and justify school policy. There is also a strong belief among a wide variety of stakeholders that the quality of decisions within the school increases in proportion to the extent to which these decisions are based on good data. In most schools, however, it appears that data use is still quite limited. Research shows that the school principal plays a key role in data use in schools. In the present study, we examine the impact of external expectations, attitude and self-efficacy on the use of data by principals. The results of a survey among 451 school principals in Flanders show that affective aspects of attitude exhibit the strongest correlation with data use by principals. The impact of cognitive attitude and self-efficacy is statistically significant, but quite limited. The same applies to the perception of external school development-orientated and accountability-orientated expectations to use data. 相似文献

We investigate the nature of protests by students (age 18 and older) in Algeria, Jordan, Morocco, and Yemen by using subsamples of students from nationally representative and acclaimed public opinion data (the 2006–07 Arab Barometer). We find between 22.1% (Jordan) and 54.7% (Yemen) participated in either the signing of petitions, or marching in street protests, or both between the years 2003–07. To explain student protest participation, we draw from the political economy literature to test four grievance-based hypotheses that link protest to student perceptions on the performance of the economy, personal family socioeconomic status, political exclusion, and preference for democracy. Ordered probit regression analyses indicate that students protest for different reasons in the four countries. We find statistical evidence that student protests are associated with grievances about the economy (Algeria and Morocco) and lack of democracy (Algeria only). Joint hypothesis tests reveal that the four grievances jointly matter in Algeria, Morocco, and Yemen but not Jordan. 相似文献

The aim of the present study was to empirically disentangle the interdependencies of the impact of nonverbal intelligence, working memory capacities, and phonological processing skills on early reading decoding and spelling within a latent variable approach. In a sample of 127 children, these cognitive preconditions were assessed before the onset of formal education, whereas reading as well as spelling achievement was measured at the end of grade 1. The findings indicate that working memory does contribute to the prediction of early reading and spelling, and that this contribution outperforms that of general intelligence and phonological recoding from long-term memory during the early steps of reading and spelling acquisition. Moreover, the results show that phonological awareness mediates the effects of working memory capacities on early literacy outcomes. The role of working memory and phonological awareness as key cognitive preconditions of early reading and spelling are discussed. 相似文献

We report on the establishment of communities of practice at four Australian institutions and evaluate their effectiveness and durability as a means of building staff and institutional capacity for interdisciplinary teaching. A community of practice approach is a potentially valuable methodology for overcoming dynamics of fragmentation, isolation and competition within universities. The communities we established were anchored by a shared focus on the topic of climate change and they worked collaboratively to build relationships of trust and reciprocity between teachers in a wide range of disciplines. The aim of each community was to improve the teaching of climate change through enabling members to integrate diverse disciplinary perspectives, to teach collaboratively, to promote innovation through exchange and to demonstrate leadership within their institutions. The key factors that made our communities effective and durable are: (1) designation of two leadership roles, activator and facilitator, (2) provision for institutional autonomy in domesticating the model to fit local circumstances and (3) a pragmatic emphasis on opportunities for teaching innovation and leadership within existing administrative structures, teaching programs and workloads. We conclude that suitably designed and resourced communities of practice are a viable means of improving interdisciplinary teaching of complex problems by facilitating both staff development and institutional learning. 相似文献

While academic librarians have always sought to create the best services for college faculty and students, the increasingly self-defined “teacher-librarian” needs more than ever to promote positive relationships and collaboration with classroom faculty. Based on a review of library literature, this article explores the nature of several disconnects between librarians and college or university faculty and examines the ways in which library outreach to faculty in its various forms seeks to bridge those gaps. The author maintains that library outreach addresses the issues between librarians and may result in higher levels of advocacy, collaboration, and collegiality. 相似文献

Theory and past research argue for the importance of understanding the effect of various campaign communication forms (e.g., newspapers, television news, radio, debates, candidate advertising, and personal discussions) on levels of issue knowledge (IK). This study used a meta-analytic approach to examine how well these forms predict IK. The aggregate analysis indicates that any of these forms can affect IK but that the different forms are not equally successful. Findings also indicate that the level of campaign interest moderates the effect of reading newspapers and watching television news and that those who watch debates in years with incumbents are less likely to learn. In addition, studies of newspapers are less likely to find significant effects in recent years, even though the issue content of newspapers has increased. The findings also suggest that television news is more likely to influence IK when levels of issue content are greater. These data indicate that measures of media use and IK can systematically influence the study results. Several conclusions are drawn from the research in the hopes of moving toward a theoretical model of communication forms and the attainment of IK. 相似文献
