This paper explores how learning and teaching innovations undertaken by externally funded projects, with a fixed remit and lifecycle, can be integrated successfully into institutional educational developments. The example and methods of one particular project, in embedding its work within and relating it to the context of wider, nationally-promoted educational designs, is utilized to illustrate the possibilities for fostering institutional change. Such change relies upon working to promote a climate whose norms support a culture of trust, where team-working can forge a broader ownership of innovation 相似文献

Recent work around the use of virtual world video games in educational contexts has conceptualised literacies as communal processes, whilst considering complex notions of collaboration through participants' multiplicity of presence in hybrid virtual / physical locations. However, further research is necessary in order to help us understand how the complex interactions afforded by such spaces influence ‐ and are influenced by ‐ children's social relationships. This article draws upon data from a year‐long ethnographic study, investigating a group of ten and eleven year old children's engagement with the video game ‘Minecraft’ as they collaborate to build a ‘virtual community’. With a particular focus on the children's improvised singing and use of song during the club, I examine how their creative practices ‐ drawing on a wide range of self‐selected resources, played out both in and out of the virtual world ‐ help to fundamentally shape the nature of the space around them. Furthermore, through examination of one particular performance, I demonstrate the importance of ensuring that such details are not written out of accounts of children interactions around technology, if we are to understand the true potential of such environments. 相似文献

Childhood obesity is a growing problem, for which multi-disciplinary interventions are needed. Purpose: This interdisciplinary intervention program was designed to improve the health of children who were obese. Methods: Twenty-five children, mean age 8.1 (1.5) years; body mass index (BMI)> 98th percentile, and their parents completed the 12-week (3 days/wk) intervention consisting of aerobic and resistance exercise appropriate to age and developmental levels. Baseline and posttest measures of blood values, fitness, and cardiovascular risk factors were performed. Data were analyzed using paired t-tests with significance accepted at P ≤ .05. Results: Significant differences between means (SD) for pre- and post-measurements were, respectively: BMI 30.31 (4.56), 27.80 (4.54), body-fat percent 43.7 (11.5), 40.7 (10.9), waist circumference 82.1 (7.1), 80.4(6.1) cm, calf circumference 34.2 (3.1), 35.2 (3.1) cm; step-test heart rate 137 (20), 126 (12) bpm, push-ups 1.0 (1.8), 5.6 (3.8), sit-ups 23.6 (12.7), 33.2 (13.8), sit-and-reach 35.1 (7.4), 41.2 (5.8) cm; systolic BP 102 (10), 108 (9) mmHg, glucose 4.9(0.3), 4.8 (0.4) mmol/L, total cholesterol 4.6 (1.0), 4.2 (0.8) mmol/L, ALT 41 (9), 35 (8) U/L, bilirubin 6.3 (2.4), 5.6 (2.1) μmol/L, and BUN 4.9 (1.1), 4.3 (0.9) mmol/L. Conclusions: This interdisciplinary intervention program positively affected the fitness and health status of children who were obese by involving the children and parents.Key Words: childhood obesity, cardiovascular risk factors, health, fitness 相似文献

The main aim of this study was to determine the test-retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s?=?0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC?=?0.95) and girls (ICC?=?0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable. 相似文献

In this paper, I discuss the "inconvenient truth" strategy of Al Gore. I argue that Gore's notion of truth upholds a conception of science and policy that narrows our understanding of climate change discourse. In one notable exchange, Gore and NASA scientist, James Hansen, disagreed about whether scientific statements based on Hansen's computer simulations were truth or opinion. This exchange is featured in An Inconvenient Truth, yet the disagreement is edited from the film and presented simply as an instance of Hansen speaking "inconvenient truth". In this article, I compare the filmic representation of Hansen's testimony with the congressional record. I place their exchange in a broader historical perspective on climate change disputation in order to discuss the implications of Gore's perspective on truth. 相似文献

A comprehensive survey of UK special schools and Pupil Referral Units (PRUs) has shown that the rapid increase in Internet use on the part of mainstream schools has not been mirrored in special education. Despite this situation, interviews with IT coordinators and Headteachers in special schools and PRUs indicate some of the reasons for creation of special school WWW homepages. The interview data indicates concerns relating to issues of separation and inclusion that have been increased by recent moves towards inclusion as a goal within the special education sector. 相似文献

This paper considers the possible impact of market forces on educational attainment in secondary schools in England and Wales. One of the main arguments made by market advocates in favour of extending programmes of school choice was that this would drive up standards. However, despite 12 years of relevant experience in the UK, it remains very difficult to test this claim. This paper examines some practical difficulties before presenting three possible models for considering changes in educational standards over time. The results are inconclusive, possibly even contradictory. The measures, such as GCSE and A levels, extending back to 1988 and beyond, have clearly increased in prevalence. In terms of these measures, students from state-funded education have also reduced the 'gap' relative to those from fee-paying institutions. However, it is not clear that either of these developments is market related. In addition, there is no evidence yet that these improvements indicate any breakage in the strong link between the socio-economic background of students and their school outcomes. 相似文献
