This review examines the use of a cognitive‐behavioural approach to anger management in children with special needs in community settings. Eighteen experimental studies involving a total of 408 children were located. The participants were mainly of high school age, with an IQ above 80, and with behavioural or emotional disorders. A moderate effect was observed for improvement in the three dimensions of anger: behaviour, cognition and emotion – although conclusions need to be very tentative. The interventions employed varied greatly in their characteristics and there were concerns about the quality of many studies. Further research is needed to investigate the interaction between intervention features and participant characteristics.  相似文献

This article applies Engeström's Activity Theory (AT) as an analytical lens to identify defining characteristics of the collaborative creative music making activities of composing and arranging. Attention is paid to the complex interrelationships among the various elements of interaction in children's collaborative creative music making as evidenced in group composing (where the activity features generation and revision of new musical material) and arranging (where the activity features creative use of existing musical material) are differentiated tasks. These include, for example, tool use in response to different tasks, the rules that govern peer collaboration, and the division of labour experienced among key players in the co-construction of decisions. Exemplary cases are sampled from data sets drawn from two separate sites one of which features a group composing task with fifth graders in a USA urban school and the other a group arranging task with eighth graders in a UK urban school. This micro-analysis is less concerned with the differences of collaborative interaction in varying cultural settings than with exploring the micro-analysis of social and language processes that characterise these differentiated creative tasks and the related activity systems. The activity system, or systems of social relations, is the unit of analysis applied across comparison-group cases using ethnographic observation, and discourse and event analysis. Analysis of the data indicates that composing and arranging involve differentiated activity systems. Important defining characteristics of the collaborative interactions, as outcomes of the children's approach to the task activities, are identified. Conclusions indicate that the application of an activity theory research perspective can provide a useful framework to make sense of the interrelated elements that characterise interaction in peer collaboration.  相似文献

The aim of this study was to develop a model to evaluate the retrieval quality of search queries performed by Dutch general practitioners using the printed Index Medicus, MEDLINE on CD-ROM, and MEDLINE through GRATEFUL MED. Four search queries related to general practice were formulated for a continuing medical education course in literature searching. The selected potential relevant citations from the course instructor and the 103 course participants together served as the basic set for the three judges to evaluate for (a) relevance and (b) quality, with the latter based on journal ranking, research design and publication type. Relevant individual citations received a citation quality score from 1 (low) to 4 (high). The overall search quality was expressed in a formula, which included the individual citation quality score of the selected and missed relevant citations, and the number of selected non-relevant citations. The outcome measures were the number and quality of relevant citations and agreement between the judges. Out of 864 citations, 139 were assessed as relevant, of which 44 citations received an individual citation quality score of 1, 76 of 2, 19 of 3 and none of 4. The level of agreement between the judges was 68% for the relevant citations, and 88% for the non-relevant citations. We describe a model for the evaluation of search queries based not only on the relevance, but also on the quality of the citations retrieved. With adaptation, this model could be generalized to other professional users, and to other bibliographic sources.  相似文献

Telematics is the combination of information technology and communication technology. Telematics applications to support educational delivery and participation in traditional European universities are rapidly becoming part of the educational setting. Sometimes they are used specifically to increase distance flexibility in participation, but this is not their only value. Telematics applications are also associated with other forms of flexibility, as well as with heightened efficiency and enrichment of the learning process, both for those in full-time traditional attendance and those participating in increasingly variable ways. In this paper, we first give an overview of the pressures for change in traditional universities in Europe and then define the change domain as involving much more than distance. Then, an overview of a variety of ways that telematics applications are being used in traditional universities in Europe will be given, including categories relating to various aspects of the course-participation experience in the individual course (such as aspects relating to lectures, self-study, and project-type group work). This will be followed by examples of new forms of course organization involving one or more institutions and also of new forms of activities in which traditional universities are becoming involved outside of their core business of mainstream course delivery. The impact on a particular institution, the University of Twente in The Netherlands, will be discussed in more detail. Issues demanding serious attention include staff and student engagement and support and technical decisions relating to the infrastructure and interface of the technology needed to make the new flexibilities possible. These are described and illustrated with examples. The difficulties in supporting this evolution in traditional universities with cost-effectiveness analysis are also noted. Finally, a reflection is made on the changing state of the division between traditional universities and universities organized around distance and open delivery. In some ways, this division is rapidly loosing meaningfulness, but certain differences that are more profound than “distance” still remain.  相似文献
