扩散性思维是一种不依常规、寻求变异、从多方面探索可能答案的思维形式。教学中,加强扩散性思维的训练,可使学生的学习范围超越现有的知识圈,逐步养成自我创造的习惯。现将我们在平面几何教学中,展开这方面训练的方法作一分类介绍。一、材料扩散。 1、以概念材料为扩散点,设想利用该种材料的各种可能性来阐述其它定义。如特殊的平行四边形的各类定义,可运用平行四边形的概念材料为扩散点进行论述。先准备四根小棒MA、
Diffusion thinking is a form of thinking that does not follow convention, seeks variation, and explores possible answers in many ways. In teaching, strengthening the training of diffusive thinking will enable students to go beyond the existing knowledge circle and gradually develop self-creation habits. Now we will introduce the method of training in plane geometry teaching. First, the proliferation of materials. 1. Using conceptual materials as diffusion points, it is envisaged to use the possibilities of the material to elaborate other definitions. For the definition of special parallelograms, the concept of parallelograms can be used to discuss diffusion points. Prepare four small sticks first,
