In study 1, the time when aggressive fighting involving 8 and 11 year‐old children took place was examined by means of direct playground observations during lunch‐time recess. There was a tendency, significant in the younger group, for there to have been more fights in the last quarter of recess. In study 2, the causes of fights, the sex of the participants, the proportion of fights that were escalated by other children joining in in a non‐conciliatory way, and the proportion in which children intervened to stop the fights were investigated, again by means of direct playground observations. The most common causes of fights were disputes over some aspect of a rule‐governed game, teasing, retaliations to accidental hurt/injury, and to a lesser extent disputes over space. Most of the fights that were observed involved boys only (90.5%), and only a minority involved boys and girls (7.9%) or just girls (1.6%). Most fights (82.5%) were not escalated by other children and most fights (92.1 %) did not involve attempts to stop them by other children. In study 3, interview data concerning children's views on fighting are reported. Many children expressed generally negative attitudes towards fighting, and there appeared to be several common ‘barriers’ that deterred children from participating. On the other hand, some children also articulated reasons why they sometimes felt it was necessary to fight. The significance of the results from the three studies for managing children's aggressive behaviour in schools is discussed.  相似文献

A self-report questionnaire about involvement in different types of bullying, what behaviours were regarded as bullying, and attitudes towards bullying, bullies and victims was completed by pupils in Year 7 (aged 11/12) through to Year 10 (aged 14/15) ( n = 170). Overall, direct verbal assault was the most commonly reported, and stealing the least frequently reported, type of bullying. For six specific types of bullying investigated, and for a composite measure of all types of bullying, significantly fewer Year 9 pupils than pupils in the other three years reported that they had behaved in these ways in the previous week. No significant sex differences emerged on these measures. These findings suggest that general patterns in bullying activities as a function of age and sex obtained in previous studies do not always hold. Although most pupils indicated that they thought that six out of eight types of behaviour viewed as bullying by researchers should be regarded as bullying, a substantial minority did not. The present study also extended bullying research by examining associations between pupils' definitions and attitudes towards bullying and their reports of bullying others. For one specific type of bullying, 'Forcing people to do things that they don't want to do', significantly fewer pupils who reported that they had behaved in this way than who reported that they had not done so included it in their definition of bullying. A consistent pattern of significant negative correlations of moderate size between attitudes and self-reported involvement in specific types of bullying were obtained. The implications of these findings for those concerned with tackling bullying in schools were discussed.  相似文献

This article comments on leadership within mainstream literature on school effectiveness/improvement, where it is almost always considered to be a factor of change. The article argues that systemic school improvement, particularly for disadvantaged children, is inextricably linked to wider social, economic and political conditions—in South Africa’s case, the political transition from apartheid to democratic government. These structural conditions and specific historical contexts are often glossed over in models of school effectiveness/improvement. Through an analysis of dysfunctional and resilient schools as a legacy of apartheid, and of the slow reconstruction of education in the post‐apartheid period, the article argues for the importance of political legitimacy and authority in school improvement. The article concludes by suggesting that states in transition require a different theoretical lens in order to understand the impact of wider social changes on schools. In such societies, the establishment of legitimacy and authority is a precondition for sustainable effectiveness and improvement, and this has implications for theorising the role of leadership in school change more generally.  相似文献

Abstract

This article reports on the results of an exploratory user-centered study that examined how technological advancements in natural language processing (NLP) such as the availability of multilingual information access (MLIA) tools impact the information searching behavior of bi/multilingual academic users. Thirty-one bi/multilingual students participated in a controlled lab-based user experiment in which they carried out two assigned tasks each on Google and WorldCat for a total of four tasks, and then completed a post experiment questionnaire. The captures from the experiment showed 86.7% of the participants using multilingual information access tools. Further analyses of the captures also showed that participants were more likely to use MLIA tools when the instructions for the task were stated in their native language. An independent samples t-test revealed that participants spent less time on their searches when they used MLIA tools. The study revealed considerable diversity in the information searching behavior of the participants, even within the same pair of languages, and even for the same user. Diversity was noted for instance, on which tasks MLIA tools were used and in how these tools were used. User-centered designed, personalized multilingual information retrieval (PMLIR) models could hold promise for best representing the information searching behavior of bi/multilingual users.  相似文献

This paper reports the results of a UK study investigating the issue of differential school effectiveness. The size of overall school effects versus departmental differences in effects on 16 year old students’ General Certificate in Secondary Education performance are examined, as well as the internal (within school) consistency of departmental effects across six GCSE subject outcomes and the stability of school and departmental effects across three GCSE cohorts (1990‐1992). A value added approach is adopted, controlling for selected student intake measures (such as attainment at secondary transfer). The findings of multilevel analyses suggest that very few schools perform both consistently (across subjects) and with stability (over time). The implications of the results are discussed in relation to the publication and interpretation of schools’ examination results as well as the use of school and departmental effectiveness measures for school self‐evaluation.
