The increased emphasis on school‐based programmes as part of initial teacher education has resulted in renewed efforts to forge more effective partnerships between higher education institutions and schools. The University of Bath has established a mentor development programme to ensure that subject mentors have an opportunity to examine ways to engage novice teachers in critical reflection about their practice while providing the support and challenge necessary to help them develop as teachers. This study is based on experienced mentors’ and their perspective on their work with novice teachers and it is a follow‐up to earlier research based on Daloz’ model (1986, Effective Teaching and Mentoring, San Francisco, Jossey Bass) of support and challenge. It examines an emerging mentoring pedagogy through which experienced mentors attempt to engage novice teachers in shaping their own vision of teaching. Three mentor profiles are discussed—the laissez‐faire, the collaborative and the imperial mentor. 相似文献

The most granular level at which COUNTER currently requires reporting of usage is for the individual journal. A number of developments have, however, meant that it is now practical to investigate the development of a COUNTER standard for the recording, reporting, and consolidation of usage statistics at the individual article level. The aim of PIRUS2 (Publisher and Institutional Repository Usage Statistics 2) was to take forward the outcomes of the original PIRUS project and build on its recommendations, by developing a prototype service (including technical, organizational, and economic models) that will enable publishers, repositories, and other organizations to generate and share authoritative, trustworthy usage statistics for the individual articles and other items that they host. The PIRUS2 project was completed in June 2011. This article covers the aims, objectives, outputs and recommendations of the project. 相似文献

The primary roles for nutrition in sprints are for recovery from training and competition and influencing training adaptations. Sprint success is determined largely by the power-to-mass ratio, so sprinters aim to increase muscle mass and power. However, extra mass that does not increase power may be detrimental. Energy and protein intake are important for increasing muscle mass. If energy balance is maintained, increased mass and strength are possible on a wide range of protein intakes, so energy intake is crucial. Most sprinters likely consume ample protein. The quantity of energy and protein intake necessary for optimal training adaptations depends on the individual athlete and training demands; specific recommendations for all sprinters are, at best, useless, and are potentially harmful. However, if carbohydrate and fat intake are sufficient to maintain energy levels, then increased protein intake is unlikely to be detrimental. The type and timing of protein intake and nutrients ingested concurrently must be considered when designing optimal nutritional strategies for increasing muscle mass and power. On race day, athletes should avoid foods that result in gastrointestinal discomfort, dehydration or sluggishness. Several supplements potentially influence sprint training or performance. Beta-alanine and bicarbonate may be useful as buffering agents in longer sprints. Creatine may be efficacious for increasing muscle mass and strength and perhaps increasing intensity of repeat sprint performance during training. 相似文献

Abstract An increasing number of researchers are investigating the effect of students’ prior knowledge and beliefs on their development of scientific concepts. Much of this research is taking place within the framework of constructivism, and is attracting the attention of science educators in non‐western countries. This integrative research review has been undertaken to help researchers and practitioners to identify issues for further investigation and reflection. The results suggest that ‘cosmetic’ attempts to nationalize western science curricula in non‐western countries are likely to prove ineffective because the problem, from the students’ perspective, is one of poor ‘fit’ between their world‐views, language meanings and prior beliefs and those inherent in the subject. A constructivist paradigm seems to offer good prospects for both understanding the problem and formulating learning strategies in science education which are better suited to non‐western cultures. Nevertheless, constructivist pedagogies imported from the West should be examined for their cultural appropriateness. 相似文献

This essay analyzes a number of issues surrounding the Menchu/Stoll dispute. In locating Stoll's criticism of Rigoberta within a larger referential arena that includes an attack on the North American academic left and an unbridled anti-Marxism, the authors attempt to reveal how Stoll's ideological agenda is functionally compatible with the larger political agenda of the New Right. The authors also attempt to reveal Stoll's distortions of Guatemalan guerrilla history as well as problems with his analysis and collection of the data. 相似文献

The publication and subsequent distribution and dissemination of Birth to Three Matters, A Framework to Support Children in their Earliest Years (DfES, 2002) marks a significant breakthrough in government recognition of the importance of the years from birth to three in shaping children's later learning. However, the Curriculum Guidance for the Foundation Stage, published the previous year, focuses upon the years from three to five. In this paper, Lesley Abbott and Ann Langston challenge the view that the Foundation Stage begins as children reach their third birthday, but rather that children are competent learners from birth, and it is at this very early stage that true foundations are laid. 相似文献

This article presents the results of two studies on the use of school self‐evaluation in the Netherlands and Flanders. It focuses on which forms of instrumental use of school self‐evaluation results can be found in schools, and how differences in self‐evaluation use between schools can be explained. Results show that the instrumental use of self‐evaluation results in both contexts was limited. Results further show that differences in the use of school self‐evaluation results can be explained by differences in school organizational characteristics, implementation characteristics, and the characteristics of the school self‐evaluation itself. Implications for theory, policy, and practice are discussed. 相似文献
