In response to the scientific evidence documenting both profound developmental changes in sleep and circadian biology during adolescence and the myriad of negative health, performance, and safety outcomes risks associated with chronic sleep loss, at least 70 public school districts in the United States, representing approximately 1,000 schools, have successfully implemented a delay in high school start times. However, despite the compelling evidence supporting school start time change as a key strategy in addressing the epidemic of adolescent sleep loss, many school districts across the country with early high school start times have not considered the option to implement later bell schedules for adolescents. Moreover, while the current scientific literature has clearly documented the positive outcomes associated with delayed high school start times, these studies contain limited information regarding the process by which school districts consider, approve and implement bell schedule changes. Thus, this in‐depth examination of those school districts that have been successful in changing their bell schedules is intended to support the efforts of other districts in various stages of contemplating this measure. We utilized a multi‐pronged approach (literature review, case studies, telephone interviews, online survey) to summarize the experiences of school districts across the United States in regard to challenges faced, strategies employed, and lessons learned in the hope that this information will be a useful tool for other school districts looking to chart a course forward to promote the health, safety, and academic opportunities of their students.  相似文献

Professional community and the problem of high school reform   总被引:1,自引:0,他引:1  
A two-year qualitative study of mathematics and English teachers in two urban comprehensive high schools investigated how teacher community serves as resource for teacher development and school reform. A school engaged in whole-school reform sustained high teacher commitment and school-level community by constituting professional community strongly at the school level, but its departments displayed varying capacity and disposition to examine problems of teaching and learning at the classroom level. In the second school, innovative teacher communities were constituted strongly at the department level in English and mathematics, but suffered problems of stress and turnover due to weak organizational supports for teacher development and school reform. Findings point both to the potential contribution of professional communities situated in subject departments and the challenge of capitalizing on such communities to advance whole-school reform. The study suggests complex relationships among organizational context, teacher community, teacher development, and institutional reform.  相似文献

Abstract. Classroom communication figures prominently in current math reform efforts. In this study, we analyze how one teacher used writing to support communication in a seventh‐grade, low‐track mathematics class. For one school year, we studied four low‐achieving students in the class. Students wrote in journals on a weekly basis. Using classroom observations and interviews with the teacher, we developed profiles of the four students, capturing their participation in class discussions. The profiles highlighted an important similarity among the four students: marginal participation in both small‐group and whole‐class discussions. However, our analysis of the students' journals identified multiple instances where the students were able to explain their mathematical reasoning, revealing their conceptual understanding, ability to explain, and skill at representing a problem. In this respect, journals potentially facilitate another important form of classroom communication. The promise of writing is that it offers an alternative to the visions of classroom communication that are strictly oral in nature.  相似文献

Recent widening participation policies have been subject to a number of criticisms; they focus on aspirations rather than differences in performance; they place less value on the aspirations of the ‘disadvantaged’ comparing them to a middle class norm; they subordinate what was a radical agenda to the demands of the economy and so constrain the available options to young people. Using data from young people who have taken part in Aimhigher initiatives in the South West of England and from teachers who have organised Aimhigher events, this paper will examine to what extent these features of policy are evidenced in the attitudes and aspirations of these pupils. It will argue that the data shows little evidence of pupils positioning themselves as inferior, that young people display instrumental attitudes to education, but that these attitudes relate to policy discourse and practice in complex ways.  相似文献

This chapter sets out the current context for historic environment management, and the associated information requirements to manage organisations successfully within the sector for the benefit of the country's heritage. The initiative undertaken by English Heritage (the English government's conservation advisors) in developing a pilot State of the Historic Environment Report is used as a case study in the collation of management information for advocacy purposes. Political support for such a development is considered, as well as the history of the report's development with its roots outside the heritage sector. The challenges of project management for report delivery are discussed, particularly where information collation and analysis is reliant on third‐party data sources, often created for separate purposes. Tourism data is focused on, showing how results from the former English Tourism Council's annual surveys of visitor attractions were used to inform key messages in the heritage sector. Comments are made on specific types of data used, and a review given of the methodology for collecting dedicated heritage management organisational data.  相似文献
