摘要：This study aims to examine the potential of synchronous text-based computer-mediated communication (SCMC) for second language acquisition and see if it can serve as another channel to offer learners opportunities for communicative practice. Fifty students from a commercial high school participated in the study, interacting with the teacher via the channels of SCMC and face-to-face communication (F2F) separately. Comparing the quantity and quality of the students’ language output via SCMC and via F2F, the study revealed that students who interacted with their teacher via SCMC significantly produced more than via F2F. In addition, these students were aware of the sequence of conversation (e.g. initiating, maintaining, and closing a dialogue). Unfortunately, compared with F2F, the average number of the accurate utterances was lower. The study concludes that SCMC provides a less tense environment which motivates EFL learners to take risks in participating in communication. Next, the SCMC task offers an authentic setting for EFL learners to be aware of reciprocal communication which can refine their conversational strategies. At last, the SCMC task may result in improved linguistic ability, but it needs more investment in time
