This study investigated how Voice Thread can influence EFL learner writing by providing collaborative activities through which learners actively participated in a feedback exchange. The activity described in this paper is creating two audio books on Voice Thread during the semester. Seventy Korean and Taiwan college students participated in this activity. During the activity, the students collaborated in constructing and negotiating meaning. The results show that any types of feedback (teachers vs peers; forms vs contents) have an effect on Korean and Taiwan college students' writing revisions. Analysis of a posttest questionnaire also reveals that students were generally motivated throughout the task, using a relatively new technology, Voice Thread, and a well-designed online collaborative task can facilitate interaction in the target language.
