Most second language (L2) researchers and teachers would agree that input, often defined as the language a learner hears or reads, plays an important role in L2 learning. There is a great deal of research investigating which types of input are most beneficial for learning, how learners process and internalize input (e.g., Schmidt, 2001), and how…

In this longitudinal study we investigated whether different distributions of instructional time would have differential effects on the acquisition of English by young (aged 11-12 years) French-speaking learners. Eleven classes of Grade 6 students (N = 230) in two versions of a similar intensive English as a second language program were followed…

Research in the field of third language acquisition has consistently identified two key factors which have an effect on the ways in which the two known languages may influence the acquisition of a third. These factors are language distance (typology) and language status (more specifically, second language, L2, or non-native language status). To…

English learners of French whose first language (L1) does not mark the perfective/imperfective distinction have shown verb semantic influence and an overall preference for perfective over imperfective in their use of second language (L2) tense-aspect markers. This study investigated whether learners whose L1 marks the perfective/imperfective…

In making decisions regarding the focus for grammar teaching, ESL instructors may take into consideration errors that appear to result from the influence of their students' first language(s) (L1). There is also evidence from language acquisition research suggesting that for some grammatical features, learners of different L1 backgrounds may face…

This paper reports on two studies that investigated the effectiveness of a contrastive analysis type of pedagogical intervention, which aimed to promote interlanguage development in the use and understanding of English possessive determiners (PDs) among adolescent second language (L2) learners. The first research question asked whether explicit…

This study investigated the relationship between L1 and the developmental sequences for the acquisition of temporal morphology that are predicted by the aspect hypothesis. The use of tense-aspect markers in 7,784 past contexts by 139 Japanese-and French-speaking ESL learners was analyzed. A repeated measures ANOVA supported the predictions of the…
