Language learning strategies (LLS) are suggested to facilitate learning and support learner autonomy. The integration of content and language in foreign language education increases the cognitive work load. Furthermore, self-efficacy has been identified as a key predictor for strategy use and language achievement. The present study aimed to (1) investigate LLS use in content-based versus traditional foreign language environments and (2) assess the impact LLS use and self-efficacy have on language proficiency. Participants were Year 9 Content and Language Integrated Learning (CLIL) and regular English as a foreign language (EFL) students (N=378) in Germany. Structural equation modelling, controlling for a range of confounding variables, showed that (1) there was no difference in LLS use between CLIL and EFL students. (2) LLS use had a negative impact while self-efficacy predicted higher language proficiency. These results suggest that students may best be supported by enhancing their self-efficacy while they should carefully choose their strategies.

Recent research has increasingly questioned the bilingual advantage for executive functions (EF). We used structural equation modeling in a large sample of Turkish immigrant and German monolingual children (N = 337; aged 5–15 years) to test associations between bilingualism and EF. Our data showed no significant group differences between Turkish immigrant and German children’s EF skills while taking into account maternal education, child gender, age, and working memory (i.e., digit span backwards). Moreover, neither Turkish immigrant children’s proficiency in either language nor their home language environment predicted EF. Our findings offer important new evidence in light of the ongoing debate about the existence of a bilingual advantage for EF.

Globally classrooms are increasingly linguistically diverse. Research often oversimplifies lived linguistic heterogeneity as binary variables: native versus non-native. Linguistic distance (LD) measures allow a fine-grained operationalization of linguistic diversity in foreign language education. This study investigated associations of cognate LDs of students’ home languages and classroom heterogeneity with English as a Foreign Language skills. Data were collected from a diverse sample of 5,130 Year 5 students in Germany. Mixed-effects linear models confirmed our hypotheses that higher individual LDs and a higher proportion of multilingual learners per classroom were both independently associated with lower English proficiency. Multilingual learners with higher cognate LDs to English and students in more linguistically heterogeneous classrooms had lower English proficiency. The results emphasize the need to assess LD in research to better differentiate between students. Foreign language classrooms seem not to address linguistic diversity adequately and need to readjust their focus to better meet multilingual learners’ needs.

With the growing popularity of early foreign language learning (EFLL) programmes in elementary schools, the transition to secondary school constitutes a crucial bridge. Ensuring a smooth transition that builds on students' L2 language proficiency and gradually shifts pedagogical approaches is key for long-term success. The present study examines students' perceptions of the transition (N = 763) two months after they switched to secondary school in Germany. Analyses included descriptive statistics and logistic regression, which controlled for the impact of individual learner characteristics. Students' receptive language proficiency was assessed to investigate its relationship with students' perceptions at this early stage of the transition. Results showed that few students perceived the transition as a disruption from their prior experience, while 43% identify both similarities and changes. Looking forward to English in secondary school and higher cognitive functions decreased the odds of perceiving the transition as a disruption. Students with lower receptive language proficiency were more likely to perceive the transition as a disruption. Pedagogical implications include policymakers providing better guidance on expectations. Initial language assessments at the beginning of the transition, paired with questionnaires gauging students' expectations, fears and prior experience, may support teachers in better addressing their students' language needs.
