课堂上学生对同一问题的认识有差异,这是必然的。有差异,就可能有争论。争论会使学生的主体意识大大增强,个体潜能尽情发挥。然而数学课堂上的争论,是建立在稳定认知结构基础上的观点交锋,是学生数学学习过程中自我表达和相互交流的一种方式,它能有效反映学生思维的真实状况,暴露学生思维的缺陷,促使学生修正思维的误区,从而催生课堂教学的亮点。
Classroom students have different understanding of the same problem, which is inevitable. There are differences, it may be controversial. Arguments will make students greatly enhance the awareness of the main body, enjoy the potential of individuals. However, the argument in mathematics class is confrontation based on the idea of stable cognitive structure. It is a way to express oneself and communicate with each other in the process of mathematics learning. It can effectively reflect the real situation of students ’thinking and expose students’ thinking Defects, prompting students to correct the errors of thinking, which spawned the bright spot in classroom teaching.
