数学教学中常常出现教师“越俎代庖”的现象,这种行为是学生数学素质难以提高的根本原因.防止措施有:引导学生在比较中发现错误;提高学生的元认知水平,引导他们自我提问,引发顿悟,发现新解法;在难点处引发学生思考,让学生自主理解题意,自主表征问题,启发学生多角度表征问题.
Teachers often appear in the teaching of mathematics phenomenon, this behavior is difficult to improve the quality of students the fundamental reason why the precautionary measures are: to guide students to find errors in the comparison; to improve students’ level of metacognition, to guide their self Asking questions, triggering epiphany and discovering new solutions; provoking students’ thinking at difficult points so that students can understand questions autonomously and characterize questions autonomously and inspire students to express questions from multiple perspectives.
