As education becomes a global enterprise, policies and practices derived from a particular cultural context are finding their way into educational systems that differ significantly from their land of origin. The article explores the cultural context of school improvement in Thailand, a developing Asian nation. Although Thailand is rapidly integrating into the global culture, it retains a strongly traditional set of cultural values and norms. Drawing upon literature review and case study data, we examine the changing nature of successful school improvement in Thailand during this period of rapid cultural transition. We also discuss implications for school improvement more generally.  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

This article takes up questions about knowledge and the school curriculum with respect to literary studies within subject English. Its intention is to focus on literary studies in English from the context of current waves of curriculum reform, rather than as part of the conversations primarily within the field of English, to raise questions about the knowledge agenda, and the knowledge-base agenda for teaching and teacher education. The selection of texts and form of study of literature within the English curriculum has long been an area of controversy. Without assuming a particular position on knowledge in this area, this article shows that important questions of what knowledge-base teachers are expected to bring to their work are elided both in current regulations and debates, and in research on ‘good teaching’ in this area. If ‘literary studies’ (as a discipline or university major) is itself an unstable and changing field, what kind of knowledge does a good English teacher bring to their work? This paper takes up these questions in the context of the Australian Curriculum and standards for teacher registration, but it also points to the way these issues about knowledge are of broader relevance for researchers and teacher education.  相似文献

Control of beak opening (gape) and peck location was examined in pigeons. Feeding pecks showed accurate guidance that positioned the seed between the beaks. At the moment of contact with the seed, gape was proportional to seed diameter, although pecks with gape less than seed diameter were more frequent following an increase in seed size during a meal. There were no substantial differences between pigeons trained to keypeck with autoshaping and those trained with operant conditioning procedures. With either procedure, water reinforcement produced keypecks with the beak closed; seed reinforcers of different sizes produced means for gape proportional to the seed diameters. Black or white circular stimuli of different sizes projected as conditioning signals had little influence upon gape, but a greater percentage of responses was directed to white stimuli. These results indicate that visual stimuli elicit and orient the peck, whereas the adjustment of gape also involves the somatosensory stimuli provided during previous experience with a particular reinforcer or food type.  相似文献
