1.连接旧基点,建立新通道,认知结构自然地扩张——同化。学生在学习新的数学内容时,教师往往会以待解决问题的形式刺激他们,此时学生就会从脑中已有的数学认知结构中去搜寻可用的资源,即结构图中的有关基点及附点,主要是基点。倘若,这些基点能对解决的问题作出解释或处理,那么新的数学内容就与原有的基点建立 1. Connect old base points to establish new channels, natural cognitive structure expansion - assimilation. When students learn new math content, teachers tend to stimulate them in the form of problems to be solved. At this point, students will search available resources from the existing mathematical cognitive structure in the brain, that is, relevant basic points in the structure diagram And points, mainly the basic point. If these points can be explained or dealt with the problem solved, then the new mathematical content with the original base established
