参加“中学数学核心概念、思想方法结构体系及教学设计的理论与实践”第八次课题研讨会之前,绍兴的子课题研究成员特别围绕这次会议的主题举行了研讨会,鲁迅中学的老师开设了研讨课“数学归纳法”.在衢州的会议中,笔者不但听到了四堂精彩的研究课,而且有幸聆听到许多专家的点评,收获很大.在听课和讨论的过程中,想的最多的是以下三个问题:1.数学归纳法到底是归纳法,还是演绎法?讨论的过程中,好几个老师提到这个问题.甚至有老师肯定的说数学归纳法是演绎法.这就奇怪了,如果是演绎法,为什么取个名字叫某某归纳法?数学当中
Before participating in the Eighth Symposium on Theory and Practice of the Core Concepts, Methods and Structures of Teaching Mathematics and Teaching Design in the Middle School, the members of the sub-topics in Shaoxing held a special seminar on the theme of the conference. The teacher set up seminar “mathematics inductive method ” In Quzhou meeting, the author not only heard four wonderful research class, but fortunate enough to hear the comments of many experts, gain a lot in the process of lectures and discussions , Think of the most is the following three questions: 1. Mathematical induction in the end is induction, or deduction? Discussion process, several teachers mentioned this problem.Many teachers even said that mathematical induction is deductive method This is strange, if it is a deductive method, why take a name somewhere inductive?
