The National Literacy Strategy (NLS) was introduced by the government in the wake of the hotly debated issue of falling educational standards in the UK. All schools were required to adopt the NLS Literacy Hour unless they could show their preferred programme would result in raised levels of achievement. My experience of delivering the Literacy Hour has been a process of adaptation to the needs of my pupils, who are drawn mainly from groups whose language backgrounds differ from that which is dominant in school. I have found that the requirements of NLS, together with many of the commercial resources used to teach it, are not appropriate for pupils from these groups and a question arose: is it the pupils who are in some way deficient or is it the approach and the resources being used? This article takes a case study of the use of a commercially produced resource to explore the model of language implicit in NLS, the kinds of resources it generates and the ways in which this creates failure in pupils from different language backgrounds. It then considers the New Literacy Studies and their implications for an alteration in our approach. 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

Development of maximal oxygen uptake in young elite male cross-country skiers: a longitudinal study.
F Ingjer 《Journal of sports sciences》1992,10(1):49-63
The aim of this study was to investigate the effects of extensive endurance training (15-25 h per week) on the development of maximal oxygen uptake (VO2 max) in boys from puberty. Maximal oxygen uptake was measured a number of times each year from the age of puberty and for the next 6-9 years in seven young male elite cross-country skiers. Mean VO2 max was measured as 76.3 and 80.1 ml kg-1 min-1 at the ages of 14 and 15 years respectively. Despite the fast rate of growth during puberty, maximal aerobic power showed seasonal variations from the age of 14, reaching a plateau at the age of 15, whereas VO2 max (ml kg-2/3 min-1) increased continuously. It is concluded that, during puberty, boys probably attain significant increases in VO2 max when appropriate amounts of endurance training are undertaken. 相似文献
