LANGUAGE RELATED OUTCOMES OF BILINGUAL EDUCATION IN PRESCHOOL AND PRIMARY SCHOOL : A SYSTEMATIC REVIEW FROM 2000 TO 2016

Abstract: Good language skills are essential to academic success. Immigrant and refugee children who enter school without previous knowledge of the societal language are more prone to failure and need of special support. The aim of this study is to describe bilingual educational program used in preschool and primary school and to examine their outcomes related to language development, both for the home language (L1) as well as the school language (L2). 17 studies were identified through a systematic literature review. Results showed a predominance of the transitional bilingual education (TBE) and two-way immersion (TWI) models in bilingual education. Language related outcomes confirmed the finding from previous literature that bilingual education doesn't inhibit L2 acquisition. Also, confirming previous literature, advantages of bilingual programs over monolingual ones are proven hard to confirm. However, several methodological issues addressed by the previous meta-analysis seem to generally persist in the most recent literature. The results of this study reiterate the need for more high- quality study in the field. Moreover, future research should also include experimentation with different languages. Finally, this argues the interest to further study and implement bilingual education programs to better accommodate the need of children with a migration background.
