The German national educational standards state explicitly that students should be enabled to successfully interact with dynamic geometry software. In a feasibility study on providing a standardized assessment instrument by digital means, in order to assess students' mathematical competencies, the implementation of a task with such a dynamic…

It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation…

Students' intelligence and self-concept of ability are critical predictors of school achievement. However, studies focusing on the relative importance of both achievement predictors have produced mixed results. To clarify these inconsistencies, the present study investigated whether the relative predictive power of students' intelligence and…

Student misbehavior is a pervasive problem and may seriously affect academic achievement. Previous research hints at different effects depending on whether achievement tests or achievement judgments are used as academic outcomes. Previous research also indicates that low achievement can conversely contribute to problem behavior and that low…

This paper provides evidence on the sources of differences in inequality in educational scores and their evolution over time in four European countries. Using Programme for International Student Assessment data from the 2000 and the 2006 waves, the paper shows that inequality decreased in Germany and Spain (two "decentralised" schooling…

This teaching module with its 80-minute videotape of lessons from U.S., Japanese, and German classrooms is designed to help moderators facilitate discussion among educators. This guide is intended to help moderators make appropriate decisions about sessions and suggest items to consider when discussing the Third International Mathematics and…
