The main objective of this study is to identify the development of students' selfreported use of metacognitive learning strategies during high school. Therefore, the study analyses the differential development patterns of 1,432 students, between grade 10 and 12, in a longitudinal sample. The results suggest that, from a global perspective, there is no development of students' self-reported use of metacognitive learning strategies during high school. The expected gender-specific differences in favour of female students are replicated in this sample. However, the self-reported use of monitoring and evaluation strategies tends to converge between genders during high school, whereas the differences in the selfreported use of planning strategies remain stable. The consequences for the understanding of metacognitive development are discussed.

This contribution provides empirical answers to the question of how teachingspecific competencies develop during participation in an international student exchange programme. The quantitative analyses of this quasi-experimental study suggest that, generally speaking, no specific developments occur during an exchange experience. These findings contradict the majority of existing literature. Possible reasons for this divergence are discussed. The interpretation of the results suggests future research should focus on the key question of pre-conditions for productive exchange experiences.

This contribution provides an overview of different facets that can be developed or promoted in exchange stays and that are specific for teachers. By systematizing the available findings with a conceptual approach, it assigns the majority of the findings to three different facets of teaching-specific 'intercultural competencies': It indicates a potential to develop professional knowledge, teaching-specific beliefs as well as motivational orientations that allow students to engage actively in challenging intercultural situations. The overview uncovers a range of methodological constraints in the prevailing literature and reveals an urgent need to add more solid evidence specifically in the context of teacher education.

Der Anspruch, dass Forschung auch «in der Praxis» oder «für die Praxis» einen Mehrwert bieten soll, materialisiert sich oft in der Forderung nach «Praxisrelevanz». Der vorliegende Beitrag diskutiert offene Fragen, die mit der gängigen Forderung nach Praxisrelevanz einhergehen, und identifiziert Voraussetzungen dafür, dass Forschungsergebnisse relevant werden können. In Anlehnung an Angebots-Nutzungs-Modelle der Unterrichtsforschung wird ein Angebots-Nutzungs-Modell für Praxisrelevanz von Forschung skizziert. Das Modell macht deutlich, dass das Erzeugen von Praxisrelevanz nicht einseitig eingefordert werden kann, sondern nur in gemeinsamer Verantwortung von Wissenschaft und Praxis gelingen kann. Der Beitrag schließt mit Überlegungen zu den Implikationen eines solchen Modells für die Lehrerinnen- und Lehrerbildung.
