浅谈“数学归纳法”的教学设计

Teaching Design of "Mathematics Inductive Method"

从思维形式说,由一般到特殊的推理就是所讲的演绎推理,与之相反则是归纳推理.在教学过程中,必须将演绎推理和归纳推理有机结合起来,更好地分析问题,解决问题.根据体育中专校学生数学基础较差,缺少对数学思想和数学概念的了解和认识等实际情况,对数学归纳法教学设计提出了自己的看法,即巧设情境,导入新课;由浅入深,循序渐进;图示结合,提供直观思维;系统总结证明流程,便于学生模仿与学习.

In terms of the form of thinking, the reasoning method from what is general to what is specific is called deduction, and induction if it goes the other way round. In the process of classroom teaching, the two methods should be combined together so that we are in a better position to analyze problems and solve them. In respect to the fact that students of intermediary school are poor in mathematics, and their knowledge as well as understanding of mathematical concepts is really scanty, the author puts forward his own ideas in the teaching of the course “Mathematics Inductive Method”. To put it more concretely, the teacher should design some role-playing situations to lead the students to a new class, teach them in a way of gradual progress, make full use of visual and pictorial materials and summarize the demonstrating procedure regularly so that they can learn and imitate easily.
