课堂话语分析技术：以新加坡数学研究课为例

An Analysis of Classroom Discourse: The Case of Mathematical Research Lessons in Singapore

在已有话语分析结构的基础上，通过话语分析编码表的开发以及Nvivo软件的数据操作，以数学教学内容的表征以及数学意义建构的步调等课堂教学维度为分析框架，从量与质的层面分析了四节研究课。这样的分析方法不仅为教师改进研究课提供了重要的依据，也为他们反思自己或他人的教学实践提供了课堂教学分析工具。

Based on the extant structure of discourse analysis, the authors analyzed four research lessons by adopting both quantitative and qualitative approaches. The authors developed the coding scheme and analyzed the lessons under the framework of the representation of teaching content and archestration of mathematical meaning construction via operating the data analysis in Nvivo. Such an analysis method not only provides evidence for teachers to improve research lessons but also the analytical tool for their reflection on their own or others' practices.
