Online and offline effects of L1 practice in L2 grammar learning: a partial replication

This study partially replicates McManus and Marsden (2016), who found that providing L1 explicit information (EI) plus task-essential practice led L2 learners to make more accurate and faster interpretations of French morphosyntax. The current study removed the original study’s L1 EI component to examine the extent and nature of its role and that of the remaining L1 practice. This design tested whether providing L1 task-essential practice only (alongside a core treatment of L2 EI plus practice) resulted in similar online and offline learning gains compared to the original study’s L1 EI plus L1 practice. We used the same online and offline tests, with a similar population of English-speaking learners of L2 French (n=19). Compared to L2 EI plus L2 practice, the findings suggest that L1 practice did not generally benefit accurate interpretation or speed of online processing, indicating that the original study’s L1 EI contributed
