Abstract
Implicit knowledge is one of the major goals of second language learning. Implicit knowledge is useful because of its automatic nature. There is a possibility that task repetition provides an opportunity to obtain implicit knowledge of chunks through frequent encounters to the same patterns during the repetition. If this frequency is enhanced by practice, learning of implicit knowledge of chunks is expected to be facilitated. The present study adopted oral repetition of chunk combinations as chunk practice to realize high-frequency encounters with patterns of chunks. This chunk practice, combined with picture description activities, was administered to the treatment group of beginner-level learners of English, while the control group engaged in the activities without the chunk practice. The treatment group outperformed the control group in the outcome of accuracy of article. However, statistically significant differences were not confirmed between the groups in fluency and accuracy of verbs and prepositions. The effect on accuracy of article endured for at least one week in the delayed performance. Transfer was not confirmed because both groups reached similar levels of unrehearsed performance.
