摘要:The article aims to outline the proposals for linking school effectiveness research and school improvement that are currently relevant in international discussion and to ask how they deal with the ‘technology deficit’ at the level of model improvement. We will first show the difference between school improvement and school effectiveness. Then, we outline areas showing basic problems associated with linking school effectiveness and school improvement. After that, we present a summary of two relevant models for linking school effectiveness research and school improvement—Comprehensive Framework of Effective School Improvement and Dynamic Model of Educational Effectiveness—and subject them to critical analysis. The result of the critical analysis is that the question arises whether a link between the two traditions leads to a complementation of their respective problems of observation rather than to a compensation of them. This, in particular, concerns the problem of causality, which gives rise to theoretical and methodological considerations in both fields of research.
