教师与学生在数学教学过程中的交互作用

Interaction of Teachers and Students in Mathematics Process

在数学教学过程中,教师与学生的作用是交互进行的.教师通过设计教学模式,评价活动效果发挥其主导作用.教学模式的设计,一是创设问题情境,二是指明认知方向;教师评价学生时,既要肯定和鼓励成功,又要质疑与修正错误.学生的主体作用表现在参与数学活动,反思认知过程.学生的数学活动一般要经历数学实验、数学猜想、数学严谨3个阶段;学生的反思是学生主动建构知识的重要环节.设计—参与—评价—反思,教师与学生的交互作用循环往复,构成了数学教学的全过程.

In mathematics teaching process, the relation between teachers and students was interactive. The teacher抯 role lied in designing the teaching model and evaluating the learning effect. While the student抯 role lied in their participating in mathematics activities and reflecting on the cognitive process. The cycling interaction between teachers and students, designing-participating-evaluating-reflecting, constituted the whole process of mathematics teaching and learning.
