Examining preservice teacher content and pedagogical content knowledge needed to teach reading in elementary school 下载免费PDF全文
Recently, increased attention has been placed on the importance of having knowledgeable and skilled teachers in order to influence reading achievement. Yet many international reports suggest that large numbers of children are not learning to read. How can we better prepare teachers with the necessary knowledge to teach reading? The current study examined the reading instructional knowledge of elementary education preservice teachers (N = 87) from two teacher education programmes. Programme A required five reading methods courses and Programme B required two methods courses. Findings indicate that the preservice teachers presented fairly robust levels of knowledge in the areas of phonological awareness, phonics, comprehension and vocabulary. However, we found statistically significant differences in knowledge based on the programme attended and the number of courses completed. Suggestions for improving reading teacher education are provided. 相似文献

In recent years it has become clear that a firm's competitive position is significantly influenced by its capacity to innovate. This paper explores the hypothesis that if there are factors operating at the regional level which inhibit this capacity, then firms located in particular regions may suffer. One such factor might be a lack of centralized scientific services. Regions under-represented in terms of a viable scientific infrastructure may find difficulty in attrating new science-based firms, and firms already in the region may find themselves at a comparative disavantage compared with firms located elsewhere. Social forces of this kind might be playing an important part in enhancing the social and economic problems of underdeveloped regions. 相似文献

The purpose of this study was to evaluate the effects of whole-body vibration (WBV) on the muscle recruitment of selected upper and lower body muscles during the baseball swing. Participants were recreationally trained males (n = 16, 22 +/- 2 years, 181.4 +/- 7.4 cm, 84.7 +/- 9.0 kg), with previous baseball experience. Subjects participated in three randomized sessions on separate days, consisting of three sets of five swings offa hitting tee. Exercises (upper and lower body dynamic and static movements) with or without WBVexposure were performed between swing sets. During each swing, the gastrocnemius, biceps femoris, gluteus maximus, pectoralis major, latissimus dorsi, and triceps brachii were evaluated for electromyographic (EMG) activity. EMG values were normalized to EMG measured during maximal voluntary isometric contraction. Statistical analysis revealed no significant differences in EMG activity across the three treatments. In addition, the results displayed a specific muscle recruitment order during the swing, starting with the lower body followed by the upper body muscles. This study was the first to report the recruitment order during the baseball swing. Although acute exposure to WBV did not significantly alter the muscle recruitment, these results may prove useful for practitioners looking to enhance baseball swing performance. 相似文献

In this study, we identified 10 sexuality education programmes from different locations in the USA that aim to give young people knowledge and skills to develop healthy relationships, as well as avoid pregnancy and disease. We conducted in-depth interviews with programme administrators to develop a series of case studies and provide concrete recommendations for education and public health professionals to implement similar approaches in their communities. Many programme administrators succeeded in developing partnerships, adapting existing curricula to suit their environments, engaging external evaluators and garnering support from teachers and parents. However, few programme developers conducted formal needs assessments before developing programmes and many struggled to implement curricula with fidelity and to employ rigorous evaluation designs. Nearly all participants identified concerns over funding as a threat to sustainability. We conclude that schools and organisations need technical assistance to build capacity for rigorous programme planning, implementation and evaluation, as well as additional funding streams to support emerging programmes. 相似文献

Based on research in universities in the North of England, this article reflects on the growing size and widening remit of the personnel function. Differences between the old and new universities are discussed together with the possible future roles of personnel within higher education. The author feels that it is unlikely, given personnel directors views of the way the personnel function is seen by Vice Chancellors and Pro-Vice-Chancellors in the older universities, that the personnel function will play a more influential role in the immediate future. Also, despite a greater role being played by the personnel function in the new universities, a seat at the'top table'has generally been denied. The author concludes that in such labour-intensive organizations as universities, the failure to empower the personnel function is somewhat shortsighted given the growing number of government policies directed towards the activities of academic staff. 相似文献

It has been suggested that the psychological stress associated with competitive sports events may help to explain the increased susceptibility to respiratory infections due to reductions in secretory immunity. In the current study, we investigated the influence of competitive exercise and psychological stress on secretory immunoglobulin A (s-IgA). Salivary s-IgA and heart rate were measured in 62 healthy young recreationally active men at rest and, in a between-subjects design, following one of four 8-min tasks: mental arithmetic, cycling at workloads of 60 to 180 W (mean = 146 W), mental arithmetic while cycling, or competitive cycling. Mental arithmetic was associated with significant increases in s-IgA concentration (mean = 49 microg.min(-1)) and s-IgA secretion rate (mean = 25 microg.ml(-1)) compared with rest, while mental arithmetic combined with exercise was associated with a significant increase in s-IgA concentration only (mean = 124 microg.min(-1)). In contrast, competitive exercise and exercise alone did not influence s-IgA concentration or secretion rate. Heart rate increased modestly to mental arithmetic (mean = 7 beats.min(-1)) and substantially, and similarly, to the three exercise tasks (mean = 56(62 beats.min(-1)). The hypothesis that the psychological stress of competitive exercise contributes to increased susceptibility to infection via reductions in s-IgA requires further investigation. 相似文献
