The purpose of this study is to examine EFL college students' spoken discourse in a pedagogical context, with a focus on how discourse markers are used. Previous studies in Taiwan on L2 language learner's discourse have focused primarily on analyzing candidates' performance in written discourse. Few attempts have been made to provide a detailed account of L2 learners' oral discourse, with respect to their use of discourse markers. The subjects are 24 freshman students at a college in northern Taiwan. Eight of the subjects are male and sixteen of them are female. A total of 120-minute audiotape recording of EFL students' oral discussion is transcribed and analyzed by a discourse analysis approach. The L2 learners' interlanguage spoken corpus is compared and contrasted with previous findings in L1. Conclusions and future directions are then drawn from the findings.
