“良好的开端是成功的一半。”好的课堂导入,能引起学生的认知冲突,激发学生的学习兴趣,从而使学生很自然地进入最佳的学习状态。因此在小学数学课堂教学中我们要从学生的心理、生理及认知规律出发,根据具体的教学内容精心设计课堂导入。选择合适的导入方法,做到导之有序,导之有法,导之有理,导之有度,这样才能引导学生在轻松活泼的气氛中学习。 “Good start is half the success. ” Good class introduction, can lead to students ’cognitive conflicts, stimulate students’ interest in learning, so that students naturally into the best learning state. Therefore, in primary school mathematics classroom teaching, we must proceed from the students’ psychology, physiology and cognition rules, and carefully design the classroom introduction according to the specific teaching content. Select the appropriate method of import, to be guided in an orderly manner, the law is guided, guided by a reasonable degree of guidance, so as to guide students in a relaxed and lively atmosphere of learning.
