A teacher's reactions to students' mathematical contributions have critical implications for shaping both teaching and learning. We present a framework for describing reacting moves that resulted from a comparative analysis between two existing frameworks; one developed by secondary teachers for parsing instructional practice and the other…

This paper attempted to illustrate how a coherence instruction could be accomplished by a teacher's discourse moves. The ultimate goal of this study was to provide mathematics teachers and educational researchers an insightful view of instructional coherence which needs more attention to achieve high quality of mathematics teaching. A Chinese…

Establishing a communication-rich classroom can be difficult. This article describes the process and findings of a practitioner action research study addressing the question of how teachers can interact with their students while they are working in groups to encourage and enhance student-to-student communication. Recommended research-based teacher…

A third-grade teacher and a teacher educator argue that, in an elementary mathematics class in which the teacher is encouraging the children to communicate and justify their mathematical ideas, the features of a mathematical task shape the mathematical discourse. They conjecture that divergent tasks, problems with many correct answers, may…
