This paper identifies a range of problems associated with putting differentiation into practice. The opinions of head teachers, subject co‐ordinators, and teachers were sought, as well as those of the curriculum support staff in the Education and Library Boards on the extent to which these problems affected primary schools in Northern Ireland, and case‐studies illuminated these views. The results showed that the curriculum support staff regarded most problems in differentiation in a more serious light than the schools themselves did, but there was agreement on the acute lack of time to deliver a differentiated curriculum, on the shortage of human resources and on the difficulties with new assessment methods. 相似文献

The aim of this study was to evaluate the preliminary efficacy and feasibility of the CrossFit Teens? resistance training programme for improving health-related fitness and resistance training skill competency in adolescents. This assessor-blinded randomised controlled trial was conducted in one secondary school in the Hunter Region, Australia, from July to September 2013. Ninety-six (96) students (age = 15.4 (.5) years, 51.5% female) were randomised into intervention (n = 51) or control (n = 45) conditions for 8-weeks (60 min twice per week). Waist circumference, body mass index (BMI), BMI-Z score (primary outcomes), cardiorespiratory fitness (shuttle run test), muscular fitness (standing jump, push-up, handgrip, curl-up test), flexibility (sit and reach) and resistance training skill competency were measured at baseline and immediate post-intervention. Feasibility measures of recruitment, retention, adherence and satisfaction were assessed. Significant group-by-time intervention effects were found for waist circumference [?3.1 cm, P < 0.001], BMI [?1.38 kg · m?2, P < 0.001], BMI-Z [?0.5 z-scores, P < 0.001], sit and reach [+3.0 cm, P < 0.001], standing jump [+0.1 m, P = 0.021] and shuttle run [+10.3 laps, P = 0.019]. Retention rate was 82.3%. All programme sessions were delivered and participants’ mean satisfaction scores ranged from 4.2 to 4.6 out of 5. The findings demonstrate that CrossFit Teens? is a feasible and efficacious programme for improving health-related fitness in adolescents. 相似文献

This article argues that Buddhists can consistently support autonomy as an educational ideal. The article defines autonomy as a matter of thinking and acting according to principles that one has oneself endorsed, showing the relationship between this ideal and the possession of an enduring self. Three central Buddhist doctrines of conditioned arising, impermanence and anatman are examined, showing a prima facie conflict between autonomy and Buddhist philosophy. Drawing on the ‘two truths’ theory of Nagarjuna, it is then shown that the prima facie conflict can be defused by noting that the self has reality at one level, but is a fiction at another level. This approach allows us a new way of seeing autonomy as an extrinsic value—as a step in the journey towards nirvana, but of no value once one has achieved nirvana. 相似文献

The article examines US community colleges from a comparative public policy perspective and asks: are they a model for Britain? The introduction provides the context for this question, stating that, while systems of education and training are recognized as vital to a nation's economic and social development, there has been a long standing lack of confidence in the effectiveness of that in Britain, especially in the intermediate post-school sector. A brief section on comparative education and public policy, is followed by a series of questions and answers aimed at providing an answer to the central question, are US community colleges a model for Britain? There follows a comprehensive review of their history, ideology, patterns of development and effectiveness. The conclusion is that, despite criticisms and shortcomings, the ‘multiple mission’ of the community colleges and their service to millions of ordinary citizens, make them a useful guide for British further education colleges. 相似文献

A cultural‐critical approach is used to explore dominant and alternative ideologies of change reflected in the metaphors of a retail‐based management staff. The case study reveals the managers as change agents were well versed in the corporate call to “get out of the box, “yet reflected a less transformational vision of change in their own discourse. Traveling metaphors used by the store‐level managers indicated a process orientation to change, but one that severely limited discussion about other possible routes toward the desired end. Suppressed alternative metaphors speaking to the personal losses and frustrations associated with change are exposed and validated in this analysis. Implications for research and practice are discussed. 相似文献

Curves are included showing the relationship between voltage and relative position of electrodes, and between voltage and counter gas pressure. Also included are experiments on the preparation of sensitive and insensitive points, and experiments with different electrode materials. These data are for a counter operated with the point at negative potential.Zeleny's conclusion that a high resistance layer of adsorbed gas exists at the point is adopted. In addition, the assumption is made that the field at the point at the onset of “self-counting” is sufficient to produce auto-electronic emission. This combination now leads to a theory which accounts for the various characteristics of the counter and explains the threshold of counting curve, the auto-counting curve, and the continuous discharge curve. Probability considerations account for the selective counting of different ionizing agents in certain voltage ranges, for the dependence of counting upon path of ionizing rays through the chamber, and for the increase of counts with increase of voltage from threshold of counting to the point where all rays are registered. 相似文献

There have been limited prospective studies investigating physical activity and physical self-perceptions in children. In this investigation, mean steps/day did not significantly change from late elementary to junior high for either boys or girls; however; boys accumulated more steps both at baseline and follow-up. Physical self-perception measures were significantly related to changes in steps/day and accounted for 21% (15% adjusted) of the variance after controlling for demographic/biological variables, R2 change = .21, adjusted R2 change = .15, F (5,88) = 4.66, p < .001. Sport competence emerged as the most important predictor t (88) = -3.76, p < .001, and was inversely related to physical activity change. The lack of opportunities to participate in sport activities normally found at the onset of adolescence may help explain this unexpected result. 相似文献
