问答、交互与课堂话语--一位高校英语专业教师的课堂话语个案分析报告

Q-and-A, interaction and classroom discourse: A case study of a university EFL teacher's classroom teaching

课堂话语分析是外/ 二语课堂研究（classroom research）的重要视角和方法，其基本理念是课堂话语的结构、模式、质量和流向（flow）直接影响学生的学习机会和质量。研究以师生间问—答模式为主要表征方式的课堂交互模式是研究课堂话语与有效教学之间的关系的主要路径。本文报告了一位高校英语专业教师的课堂话语个案分析，分析的焦点是课堂中师生间的问—答性质、模式和课堂话语时间分布。研究结果表明在本个案研究的课堂的语境下，我们或需重新考量外语课堂交互模式的概念和意义，有必要提出显性话语/ 交互和隐性话语/ 交互模式的概念。

Classroom discourse analysis (CDA) has been an important perspective in EFL/ESL classroom research. The basic assumption behind is that the structure， pattern， quality and flow of classroom discourse may directly influence students' learning opportunities and quality. An important way to reveal the relationship between classroom discourse and effective classroom teaching is to examine classroom interactional patterns mostly represented by question-and-answer between teacher and student. This paper reports a case study of a university EFL teacher's classroom discourse， focusing on the nature， pattern and distribution of question-and-answer between the teacher and the students. The results suggest that in the context of the examined classes it is arguably necessary to reconsider the concept and meaning of EFL classroom interaction and propose as well the notions of explicit discourse/interaction and implicit discourse/interaction in CD research.
