This is a mixed-methods study investigating the effects of oral repetition tasks on Japanese students' use of lexcial phrases in communicative EFL instruction. The quantitative study showed that oral repetition facilitated the students' short-term memory of target lexical phrases but it did not translate into their long-term memory or use of the phrases. The qualitative study indicated that the participants perceived interpersonal conversations and small-group discussions in English as enjoyable and useful activities. / CITE/Language Arts
