概念的教学举足轻重,可以说理解概念是一切数学活动的基础.李邦河院士曾说:“数学根本上是玩概念的,不是玩技巧.技巧不足道也!”然而,当前数学教师以解题教学代替概念教学的现象十分普遍,大量解题带来了学习的高效性,而其隐蔽的缺失常常被人们所忽略.基于这样的考虑,杜宾斯基等人建立了APOS理论——一个可以促进我们有效教学的数学教学理论.从20世纪90年代起,APOS理论就被介绍到我国的数学教育界,它是为数
The concept of teaching is pivotal, it can be said that the concept of understanding is the foundation of all mathematical activities .Li BangheAcademician once said: “Mathematics is essentially playing concept, not playing skills .Insufficient skills! ” However, the current mathematics teachers to solve problems in teaching The phenomenon of replacing the concept of teaching is very common, a large number of problem-solving brings the efficiency of learning, and its hidden absence is often overlooked.Based on such considerations, Dubinsky and others established APOS theory - one can promote Our effective teaching theory of mathematical teaching since the 1990s, APOS theory has been introduced to our mathematics education sector, which is the number
