数学实践：数学课堂交流之数学化分析

Mathematical Practice: the Mathematics Variation Analysis of Mathematical Classroom Communication

教师对学生在学习中表现出的基础障碍往往缺乏敏感性，造成师生问难以进行有效的数学交流。本文从对数学变化分析的角度来阐释数学课堂交流的困难性，并在此基础上提出具有实践意义的数学课堂教学建议。

The lack of sensibility to the basic barriers in the students’ classroom performance during the mathematics learning gives rise to the difficulty in making effective mathematical classroom communication between teachers and students. The paper elucidates the difficulty in mathematical classroom communication from the angle of mathematics variation analysis， based on which some feasible suggestions on mathematics classroom teaching are brought forward.
