习题课的教学目的是让学生独立地、创造性地掌握数学知识,发展数学思维能力,从而提高数学修养.为此,在习题课教学中,教师应善于放手让学生自主地思考,诚如波利亚所言,“一个数学教师如果把分配给他的时间塞满例行运算来训练学生,他就扼杀了学生的兴趣”.当然采取“放”的方法,? The purpose of the exercise class is to enable students to master mathematics knowledge independently and creatively, develop mathematics thinking skills, and thus improve mathematics cultivation. Therefore, in the exercise class teaching, teachers should be good at letting students think independently, such as Poli. As Ah said, “A mathematics teacher would kill students’ interest if he had trained him with the routines assigned to him.”
