The effects of distributed practice on second language fluency development

Abstract

This study examined the effects of distributed practice on second language (L2) speech fluency development. A total of 116 Japanese L2 learners of English were randomly divided into experimental or control conditions. Learners assigned to the experimental groups engaged in four fluency training sessions either in a short-spaced (1-day interval) or long-spaced (7-day interval) condition. Although different learning trajectories were observed during the training phase, the posttests conducted 7 and 28 days after the training showed similar fluency gains for the two groups, indicating that short- and long-spaced conditions were equally effective for developing L2 fluency. The current study extends the line of research in distributed practice and task repetition for L2 fluency development.
