BILINGUAL EDUCATION'S IMPACT ON FIRST-LEVEL STUDENTS' LEARNING OUTCOMES

Abstract

This meta-analysis explores the impact of bilingual education on dual language learners' (DLLs) academic performance, revealing that the overall effect is modest and not statistically significant. However, it highlights several key factors requiring further research. The type of bilingual program significantly influences outcomes, with dual language programs outperforming transitional ones. Academic subjects also play a role, as multilingual instruction particularly benefits subjects like mathematics. Additionally, the language used for assessment affects results, emphasizing the need to consider both first and second language proficiency. The study finds that the effectiveness of bilingual education is consistent across primary education levels. Future research should continue to investigate these factors to optimize bilingual education strategies and enhance academic performance for all students.
