教育家苏霍姆林斯基说过“所有智力方面的工作都要依赖于兴趣”。因此我们在注重发展学生智力，培养学生的创新意识的同时，也要高度重视对学习兴趣的开发与利用。笔者在多年初中几何教学中，时时把握学生心理特征，注重诱导、激发、培养和提高学生的兴趣，收到了较好的效果。 The educator Sukhomlinski said that “all intellectual tasks depend on interest.” Therefore, while we focus on developing students’ intelligence and cultivating students’ sense of innovation, we must also attach great importance to the development and use of learning interests. In the middle and early years of the geometry teaching, the author always grasps the psychological characteristics of students and pays attention to inducing, inspiring, cultivating and improving students’ interests. It has received good results.
