A conversation analytic study on L2 communicative competence necessary for various opinion-exchanging discussions

在这个项目中，我考察了一种特定的社交互动环境，以便与同龄人“争论”和“讨论”，以及日语的第二语言使用者(相比之下，说第一语言的人)在这种情况下会如何处理自己。这两个小组每次由3~4人组成，每组讨论约30分钟，共5次。使用会话分析对这些讨论的语料库进行了分析。随着这个项目的主题，即调查二语说话者在辩论和讨论中的表现，另一个相关的主题也出现了。该项目随后调查了一个人如何以互动的方式将他/她的观点传达给其他人，即重新考虑通常被理解为交际能力的东西。为了做到这一点，这项研究检查了额外的数据，如课堂互动。在研究期间发表了两篇期刊文章，另外两篇论文计划在2012年和2013年以章节形式出版。

In this project, I examined a particular social interactional context to "argue" and "discuss" with peers, and how L2 users of Japanese (and in comparison, L1 speakers of Japanese) would handle themselves in such a situation. These two groups which consisting of 3～4 people at one time engaged in a discussion for approximately 30 minutes each, for five times. The corpus of these discussions was analyzed using conversation analysis. Along with the main theme of this project, that is to investigate L2 speakers' performance in arguing and discussing, another related theme has come up. The project then investigated how one interactionally delivers his/her opinion to others, i.e., re-considering what has been understood as communicative competence in general. In order to do so, the study has examined additional data such as classroom interaction. Two journal articles were published during the period of research, and two more papers are planned to come out as a chapter in a volume in 2012 and 2013.
