Continuous observation of the physical activity of 56 preadolescent children was conducted in four regions of England from October 1988 to July 1989. Observations were undertaken during school break times, lunch times, and physical education lessons, as well as during the children's free time. Of total time observed, the children spent 32.4% of it engaged in moderate to vigorous physical activity (MVPA). Children were shown to be most active during school breaks and least active during free time at home. However, it is thought that cardiorespiratory benefits are best achieved by participation in sustained periods of MVPA. Only 8 (14%) of the 56 children were observed to participate in MVPA for sustained periods of 20 min or longer. A random sample of 55 physical education lessons was observed. Only 6 children engaged in MVPA for sustained periods of 5 min or more, and no children participated in MVPA for 10 min or longer. The implications of these results are that, although the children engaged in a reasonable amount of MVPA, it may not have been sustained for periods of sufficient length to produce a cardiovascular training response. Consideration is given to ways of promoting lifelong involvement in physical activity.  相似文献

Despite increased enrollment, outcomes such as grade point average (GPA), persistence, and graduation rates for college students with learning disabilities (LD) continue to lag behind those of their nondisabled peers. Reasons for the differences vary but may include academic and social integration, factors identified as important to the success of college students in general. This research investigated the relative influence of background characteristics, precollege achievement, and college integration variables on the academic success and intent to persist of college freshmen and sophomores with LD. While academic and social integration were not unique predictors of college GPA, both integration variables were unique predictors of intent to persist. The findings suggest that beyond high school achievement and background characteristics, college experiences as captured by academic and social integration are promising constructs to help explain the persistence of college students with LD. Implications for future research and practices for high school and college personnel are discussed.  相似文献

Anne Maddison is deputy headteacher, with responsibility for curriculum, at the Milestone School, a special school created recently after the amalgamation of three smaller schools. In this article, she describes the development of an outcomes-based curriculum for pupils with a range of learning difficulties aged from two to 16 years. Anne Maddison sets out the rationale for her work in the context of a need to promote shared approaches to teaching and learning at this newly formed school.
The curriculum development project described here was evaluated using questionnaires, interviews and the analysis of documents and practice as part of a case study in school-based enquiry. Anne Maddison used the outcomes of these processes as part of her Doctor of Education (EdD): Educational Leadership course at Lincoln University.
Since this article was written, the Milestone School has undergone its first Ofsted inspection. The report noted that teaching at the school is 'of very high quality' and the curriculum 'is very good'. Inspectors noted that 'the planning of schemes of work, which are being developed with different subjects being focused on each year, is exemplary, with clear outcomes for pupils of different abilities'. While Anne Maddison's article details the experience of one school, her analysis may be of interest to other school managers, teachers, governors or advisers who are seeking to promote the development of a more inclusive curriculum.  相似文献

In recent years university presses have undergone some significant changes, such as expansion of their scope to include materials that may have appeal beyond the scholarly market. This article investigates, through the use of a survey of university libraries, the acquisition of university press products by libraries. In general, recent years have been changes in the relationship between university presses and libraries that have resulted in fewer items being purchased by the libraries.  相似文献
