Observational study of university students' interactional competence: Short-time and longitudinal study

运用会话分析的框架，本研究考察了大学生在模拟现实世界商务谈判的讨论任务中的互动能力。本研究分析的数据来自三年来收集的大约160小时的英语课堂小组讨论任务的视频记录。分析表明：(a)学生通过各种语言和非语言资源的运用展示了他们的英语互动能力；(b)为学生提供这种讨论任务可能为常规语言使用创造条件，可以适用于课堂之外；(c) MEXT政策已经开始反映在学生的互动能力上。(d)会话分析方法对于阐明第二语言使用者的互动能力以及检查学生实际执行政府语言政策的程度至关重要。

Using the framework of Conversation Analysis, this study examined university students' interactional competence during discussion tasks that simulate real-world business negotiations. The data analyzed for this study came from approximately 160 hours of video-recorded English classroom interaction in small-group discussion tasks collected over three years. The analysis demonstrated that (a) the students displayed their interactional competence in English through the deployment of various verbal and nonverbal resources, (b) providing students with this kind of discussion task may create conditions for routinizing language use that can be applicable outside the classroom, (c) the MEXT policy has begun to be reflected in students' interactional competence, and (d) the Conversation Analysis method is crucial for elucidating the second language speakers' interactional competence as well as examining the degree of students' actual implementation of the government's language policies.
