摘要
解读中学新课标对"对称与群"专题的要求,分析了高师近世代数课程群论的特点。从高中选修课需要的角度,提出高师近世代数介绍群定义的教学策略:借助正多边形的对称性,引入定义;挖掘群的内涵和外延,理解定义;重新认识特殊的群,巩固定义。
The criterion of symmetry and group and the characteristics of modem algebra for normal college are analyzed. Considering the needs of high school elective courses, we proposed some strategies for teaching the definition of group in modem al- gebra for normal college, such as introducing the definition hy the symmetry of regular polygon, understanding the definition by ex- ploring the intension and extension of group, and consolidating the definition by reconsidering the special groups.
