Abstract The following paper should be seen as an addition to that provided in the Proceedings of the 7th ICTE.’ For reasons of brevity, it does not deal to any large extent with the background to the project, but details the progress of a study into the effects of introducing laptops into primary (elementary) school. The project has provided every pupil in one class with a laptop computer and has tracked the use being made of it as a curriculum tool for writing. The second phase of the project is under way, with a completion date of April 1991. 相似文献

Interaction of wrestling shoe and competition surface: effects on coefficient of friction with implications for injury 总被引:1,自引:0,他引:1

The purpose of this study was to determine whether there is a significant difference in the co-efficient of friction (Fc) between old versus new wrestling shoes and mats and to investigate the effect of perspiration. Fc was measured by dragging a weighted shoe over a wrestling mat surface and measuring the vertical and horizontal forces produced. Three different shoe conditions were assessed over two mat types for both wet and dry conditions for a total of 12 conditions. To simulate the wet condition, saline solution was smeared over the surface of the mat. There was a significant effect of shoe, mat, and wet/dry conditions. In addition, significant interactions of shoe by mat, shoe by dry/wet, and mat by dry/wet were observed. Overall, Fc was 36% higher for the new wrestling mat compared to the old wrestling mat. Application of the saline solution reduced Fc by 14% compared to the dry condition. Comparison of the mean Fc for all three shoe types revealed the Fc for the older design shoe was 23% to 28% lower than the brand new shoe and the worn newer design, respectively. A high Fc, such as in the new mat/new shoe combination, has the potential to increase the risk of knee and ankle injuries by fixing the foot more securely to the ground. 相似文献

Significant numbers of children (6% of 11‐year‐olds) have difficulties learning to read. Meanwhile, children who receive appropriate support from their parents do better in literacy than those who do not. This study uses a case study approach to investigate how digital games designed to support struggling readers in school were used at home, by the parents of six children to support their children’s literacy. Mostly, the children enjoyed playing the games and believe that it helped improve their reading. The parents all valued the opportunity to participate in their child’s learning and believe that the games’ approach to learning is effective. The study considers key influences on the successful use of games to support struggling readers (repetition, feedback, motivation, self‐efficacy, parental beliefs) and raises questions, further consideration of which might usefully inform the future development of effective game‐based learning. 相似文献

This article considers a secondary science department that has, since 2000, developed distributed leadership as a form of human capacity building. Using a longitudinal ethnographic case study allowed us to consider how distributed leadership can be nurtured and developed in a department. Our analysis centres on two key issues: the nature and pattern of distributed leadership practices and the continuity that provides coherence to those practices. From our analysis, there appear to be two major conclusions. The first of these is the need for administrators to be purposeful in the appointments that they make to formal leadership positions. To enact distributed leadership practices requires leaders who can exercise both formal power and influence. The second conclusion relates to the time required for continuity of leadership practices to give rise to changes that lead to teachers managing the teaching and learning programme. 相似文献

The study extends agenda-setting research by examining issuediversity as a consequence of media exposure. Results from twosurveysone conducted in the United States, the otherin Taiwanillustrate differences in the cultures of thetwo samples. In general, older individuals who find low utilityin advertising information but who read a variety of newspapersand feel a strong civic duty to keep informed believe thereare many important issues facing the United States. Younger,highly educated individuals who have a high interest in politicalnews and who read a variety of newspapers believe there aremany important issues facing Taiwan. 相似文献
