Prior research showed that interleaved practice (studying multiple skills at once) is more effective than blocked practice (studying only one skill at a time). This study aims to replicate the benefits of interleaved practice on the proceduralization of second language (L2) syntax and further examines the role of working memory (WM) in different…

The impacts of task characteristics on second language (L2) writing require further exploration. This study examined the effects of increasing task complexity on L2 argumentative writing. Upper-intermediate L2 learners performed two writing tasks with varying degrees of complexity in relation to the number of elements and the degree of reasoning.…

Twenty-nine L2 Chinese learners at a large New Zealand university performed a narrative task after watching a…

The current study compared the effectiveness of computer-delivered task-essential practice coupled with feedback consisting of (1) negative evidence with metalinguistic information (NE+MI) or (2) negative evidence without metalinguistic information (NE-MI) in promoting absolute beginners' (n = 58) initial learning of aspects of Latin…
