Prof. Kos erforscht aktuell, wie Fremdsprachenunterricht in realen Klassenzimmern funktioniert — insbesondere Peer-Collaboration beim Schreiben und Sprechen, Spracherwerb in altersgemischten Klassen sowie die Ausbildung von Lehrkräften für Content and Language Integrated Learning (CLIL). Seine Arbeiten kombinieren Beobachtungen aus dem Schulalltag mit qualitativen Analysen von Schüler-Interaktionen. Für Schulen und Lehrerausbildungsinstitutionen liefert er evidenzbasierte Erkenntnisse darüber, wie Aufgabendesign und Peer-Unterstützung den Spracherwerb fördern und wie angehende Lehrkräfte besser auf mehrsprachige und heterogene Lerngruppen vorbereitet werden können. Die Forschung ist relevant für Schulentwicklung, Lehrerfortbildung und die Gestaltung von Fremdsprachencurricula in Deutschland und darüber hinaus.

Abstract This study explored peer support among grade 5 learners of English as a foreign language (N = 24) interacting during regular lessons. Grounded in sociocultural theory and applying mixed‐method research methodology, this study explored to what extent and how young learners support one another during classroom tasks targeting lexical phrases. Moreover, it investigated to what extent such support accounts for learning opportunities. Students relied mainly on linguistic support through suggesting or using resources while social–emotional support such as offering support, giving positive feedback, or inviting partners’ participation was limited. The analysis also revealed instances of lack of support in the form of reprimanding, impatience, expressing a lack of awareness of the partner's contribution, or disrespecting peer's linguistic resources which, however, differed widely across pairs.

Abstract An increasing body of research has explored patterns of interaction and peer support among young learners. Although some studies suggest that young learners can engage in collaboration when interacting on tasks, other studies indicate the opposite. Moreover, despite the claims that peer collaboration is conducive to learning, studies have not paid enough attention to the “how” to enhance peer collaboration on tasks. This article proposes that enhancing peer collaboration is a powerful pedagogical tool that promotes communication among peers and mutual support, thus positively affecting learners' performance during classroom work. At the heart of the article, it discusses some practical pedagogical ideas for teachers which focus on teaching collaborative principles and strategies during classroom work. Although it pays particular attention to the context of primary school English foreign language teaching, its content may also be relevant to primary school teachers of other foreign and second languages.

Abstract Although foreign language instruction in mixed-age (M-A) is gaining popularity (Heizmann and Ries and Wicki 2015; Lau and Juby-Smith and Desbiens, 2017; Shahid Kazi and Moghal and Aziz 2018; Thurn 2011), the research is scarce. Drawing from multiple data sources, this study investigated to what extent do peer interactions among M-A and same-age (S-A) pairs aid L2 development and how students perceive their interactions. In this study, the same learners ( N =24) aged between 10 and 12 interacted with the same and different age partners during common classroom lessons in two EFL classrooms. The results suggest that both S-A and M-A peer interactions aided L2 development. Although S-A pairs outperformed M-A pairs on the post-test, the results are not statistically significant. The analysis of students’ perceptions revealed that the majority of students prefer working in S-A to M-A pairs. In addition to age/proficiency differences, factors such as students’ relationships and perceptions of one’s own and partner’s proficiency greatly impact how they interact with one another.
