Recently, European school systems have seen various attempts to ‘modernise’ their governance. Market and competition oriented reforms have not been central to governance innovation strategies in German speaking countries, however, their number and relevance is rising in recent years. A free school choice policy which abolishes “school districts” which legally define fixed school catchment areas was introduced in the school year of 2007/2008 in the Austrian city of Linz.The effects of the implementation of this policy on the primary school sector were studied by a standardised questionnaire administered to a representative sample of 3425 parents of five age groups of primary school children. The return rate was about 55%. By special measures during data collection a satisfactory representation of parents with migrant background was achieved.Three questions are discussed in the paper: (1) Is there a rise in segregation in schools as a result of free choice policy? (2) Is there a change in the composition of the student population in different schools as a result of free choice policy? (3) Is there a change in parent school choice behaviour of as a result of free choice policy?Our data indicates that segregation in primary schools with respect to ethnic and social family characteristics increases after the policy implementation, but the sample size is too small to find significant results. In addition, no significant change is observed in the social composition of schools. In accordance with the previous findings no significant modifications of choice behaviour occur for different ethnic or social groups after free choice. However changes in choice motives can be observed.  相似文献

Abstract

Understanding teachers' perceptions of a web-based, case-based learning environment provides insight into the effective development and deployment of such conditions for preparing educators. CaseNET–a web-based, case-method teaching environment for professional educators–serves as both a source of information as well as a space for inservice and preservice teachers to interact with one another and to contemplate current educational issues as they relate to real-world teaching. A qualitative analysis of over 400 participants was conducted and results provided. Participants perceived CaseNETas an opportunity to engage in professional development via exploration, reflection, collaboration, and hands-on interactions with authentic teaching tasks. Results suggest that the combination of cases and technology provides a valued opportunity to engage developing teachers in professional behaviors.  相似文献

Following Cronbach (1970) and others, it is useful to decompose test score variation into common factor, time‐specific, item‐specific, and residual components. In the traditional approach to factor analysis, only two sources of variance can be estimated: common factor variance and a uniqueness term that confounds specific sources of variation and residual error. When the same items are measured on different occasions, however, it is possible to separate specific variance and residual error. Two approaches, the first‐order approach described by Raffalovich and Bohrnstedt (1987) and a second‐order approach based on Jöreskog and Sörbom (1989; Jöreskog, 1974) are considered initially. The two approaches, although based on different rationales, both suffer a similar weakness in that two of the four sources of variance are confounded. In the Raffalovich and Bohrnstedt approach, time‐specific variance is confounded with common factor variance that generalizes across items and time. In the second‐order approach based on Jöreskog and Sörbom, time‐specific variance is confounded with residual error. Here we demonstrate that by combining features from both approaches we can eliminate these weaknesses and estimate all four of Cronbach's sources of variance, and that this combined approach is easily generalized to a wide variety of applications.  相似文献
