An analysis of long jump performance, including both the approach and aerial phases, is applied to Bob Beamon's legendary leap at the Mexico City Olympic Games of 1968. It is shown that the combined effects of altitude and wind assistance yielded an increment in the length of the jump of about 31 cm, compared to a corresponding jump at sea level under still air conditions. The main factor is shown to be the increased sprinting speed attained under favourable conditions of wind and altitude. 相似文献

Improving the Academic Performance of Non‐native English‐Speaking Students: the Contribution of Pre‐sessional English Language Programmes 下载免费PDF全文
There is an established, if weak, inverse relationship between levels of English language proficiency and academic performance in higher education. In response, higher education institutions (HEIs) insist upon minimum entry requirements concerning language for international applicants. Many HEIs now also offer pre‐sessional English courses to bring applicants up to the designated language requirement. This paper revisits the research into language proficiency and academic performance using data on all full‐time students (17,925) attending a major UK HEI in the academic year 2011–2012, 4,342 of whom were non‐native English speakers. The findings confirm that while higher International English Language Testing System (IELTS) marks at entry translate into higher grade point averages (GPAs), students who undertake pre‐sessional courses do notably worse in GPA terms than students who arrive with acceptable (for the course) IELTS scores. These findings suggest HEIs (and, by extension, international students) could benefit from a review regarding the appropriateness of current pre‐sessional English language proficiency programmes. 相似文献

Education has been the subject of much debate during the late 1980s. The Education Reform Act 1988 marks a major shift to the right in central government approaches to state education. However, despite these changes there has been little attempt to develop an alternative vision of education not founded in the ideology of ‘the market’. In 1989, Women for Socialism held a conference which brought together socialist‐feminists to begin the process of building a vision of an education system which would challenge the oppressions of class, gender and race. 相似文献
