基于建构主义的逆矩阵教学设计与实践

针对逆矩阵教学中重计算、轻思想的问题,结合建构主义教学理念,在教学中分析学生已有的知识结构,从逆矩阵的几何背景的角度引入定义,注重逆矩阵与其相关知识点的联结,利用数学软件开展教学拓展,培养学生抽象思维能力和解决实际问题的能力。

In order to solve problems of emphasizing calculation and neglecting thought appearing in reverse matrix teaching, construtivism theory was utilized toanalyze cognitive structure of students, inverse matrix was introduced from the point of view geometric, the connection between the inverse matrix and its related knowledge was focused, mathematics software was used to expand teaching tocultivate the students’ ability of abstract thinking and the practical problems-solving.
