Exposure to bullying,reactions and psychological adjustment of secondary school students

A sample of 575 secondary school students aged 11–15 years was administered a checklist on experiences of bullying, then divided into groups of victims, witnesses and not exposed, and by gender. Participants completed the Strengths and Difficulties Questionnaire on psychosocial adjustment. Victims and witnesses completed another questionnaire on the extent to which they would endorse retaliation/vengeance and avoidance towards the perpetrator. Girls reported being victimised significantly more than boys. Amongst victims, boys scored higher than girls on desire for retaliation/vengeance and on externalising behaviours; girls scored higher on internalising behaviour. Experience of bullying victimisation, rather than merely witnessing it or not being exposed to it, was associated with internalising behaviours for both boys and girls. These measures of psychosocial adjustment were associated with the desire for retaliation/vengeance. Implications are discussed of the links between gender, exposure to bullying, reactions and psychosocial adjustment of secondary school children.     

An NCME Instructional Module on Booklet Designs in Large-Scale Assessments of Student Achievement: Theory and Practice

In most large-scale assessments of student achievement, several broad content domains are tested. Because more items are needed to cover the content domains than can be presented in the limited testing time to each individual student, multiple test forms or booklets are utilized to distribute the items to the students. The construction of an appropriate booklet design is a complex and challenging endeavor that has far-reaching implications for data calibration and score reporting. This module describes the construction of booklet designs as the task of allocating items to booklets under context-specific constraints. Several types of experimental designs are presented that can be used as booklet designs. The theoretical properties and construction principles for each type of design are discussed and illustrated with examples. Finally, the evaluation of booklet designs is described and future directions for researching, teaching, and reporting on booklet designs for large-scale assessments of student achievement are identified.     

Recognising Prior Learning: Understanding the Relations Among Experience, Learning and Recognition from a Constructivist Perspective

This article discusses the relation between experience and learning in the context of recognition of prior learning (RPL) and from an experiential constructivist perspective. The study is based on a case of in-service training, based on RPL, in the care sector for elderly people. The data consist of interviews with actors in this process, which have been analysed with a qualitative interpretative approach. The results show how prior learning plays a central role in the training process, both on an individual and a collective level. The participants’ prior learning is taken as the starting point, particularly in learning conversations where prior learning is made visible and used, and where participants learn from each other. Further, new learning is taking place as a consequence of the recognition process, and the study particularly highlights how prior experiences could be the basis of new learning in a process of reflection and discussion.     

Modellierung und Simulation hybrider Systeme mit Smile

Zusammenfassung. Es wird eine werkzeugunterstützte Entwicklungsmethodik vorgestellt, die der Erstellung von Berechnungsmodellen für die Simulation hybrider physikalisch-technischer Systeme dient. Dafür werden verschiedene Modellbeschreibungstechniken dargestellt und klassifiziert, die anschlie?end in einen falltypischen Entwicklungsproze? eingebettet werden, der auf hybriden Erweiterungen von UML und Z basiert. Die Simulationsumgebung Smile (http://buran.fb10.tu-berlin.de/Energietechnik/EVT\_KT/smile/) erm?glicht schlie?lich die generische Erzeugung eines ausführbaren Simulators. Architektur und Kernkomponenten dieses Systems, wie beispielsweise L?sungsverfahren und Experimentshell, werden eingehender diskutiert. Ein Anwendungsbeispiel illustriert den beschriebenen Entwicklungsproze?. Eingegangen am 15. Juli 1999 / Angenommen am 12. November 1999     

球类比赛数学模拟竞技诊断的理论与实践--以乒乓球比赛分析为例

介绍了球类比赛数学模拟竞技诊断的理论与方法,并用乒乓球比赛的数学模拟竞技诊断实例进行了说明。数学模拟竞技诊断的基本思想是用一个比赛状态(技术或战术)转移概率矩阵概括地描述一场球类比赛,在此基础上通过马尔可夫链计算比赛获胜概率并进一步确定各种比赛状态(技术或战术)的竞技效率值。与传统的球类比赛分析方法相比较,数学模拟竞技诊断不但能通过各种比赛状态的转移概率对技、战术进行描述性统计分析,而且能确定各种比赛状态(技术或战术)对整场比赛获胜概率的影响。
