The Impact of Group Characteristics of Collaborative Engagement on Language Learning in Collaborative Writing Tasks
Although collaborative engagement is a crucial predictor of peer interaction and language learning,it has been overlooked by researchers.This study investigated the collaborative engage-ment of 72 non-English major students and its impact on their language learning performance in collaborative writing tasks through a questionnaire survey,audio-recorded discussions,and writ-ten texts.The results reveal that(1)collaborative engagement is characterized by divergence,in-teractivity,collectivity and dynamism;there are obvious differences in the group characteristics possessed by different types of individual and collaborative group engagement;(2)collaborative engagement has positive effects on language noticing and linguistic problem-solving during peer interaction;(3)high-level collaborative engagement is good for learners'sustained language de-velopment.The present study suggests that teachers should consider learners'group characteris-tics of collaborative engagement in teaching practice to enhance the effectiveness of collabora-tive writing.
