| Abstract: | 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. |
