Emergent bilinguals in a digital world: a dynamic analysis of long-term L2 development in (pre)primary school children

Abstract

Abstract In this study, I present dense, longitudinal data exploring the insights that a Complex Dynamic Systems Theory (CDST) perspective can bring to bear on patterns of relationships found between learner individual differences – notably age of onset (AO) and extracurricular L2 English use – in children in (pre)primary programs in Switzerland. We studied 71 children who had received 50/50 bilingual instruction in German and English (so-called “partial CLIL” programs) as well as 105 children in “minimal CLIL” programs with almost uniquely monolingual German instruction (90% German, 10% English). In the data analysis, (1) generalized additive mixed modeling (GAMM) was combined with (2) mixed-effects regression modeling. The findings show that AO may exert an effect on L2 performance in bilingual but not traditional instructional settings. Furthermore, contact with English outside school is a strong predictor for learner outcome, regardless of the intensity of instruction and an early or late start respectively. We conclude that the traditional view of the age factor in instructional settings needs to give way to a new understanding of L2 development in intensive exposure conditions, in which age of acquisition is seen as a major determinant.
