数学教学既求真,也求美.数学归纳法具有在语言结构、思维模式、方法创新等方面的美.借助信息技术工具,可活化数学归纳法程式化的推理模型,演示其生动活泼的存在形态,激发学生对数学的学习兴趣.一、课前导学感知美本节课作为电子书包项目的实验课,课前给学生发布了数学归纳法的情景素材库.预习任务有:分析击鼓传花的原理;分析体育课报数的原理;分析部队行军秘传口令的原理;用数学归纳法的原理,帮老师设计一个课堂能提问到所有同学的操作方法.数学归纳法的中心思想是:用一次验证和
Mathematical teaching not only seek truth, but also beauty.Mathematical induction has the beauty in terms of language structure, thinking mode, method innovation, etc. With the help of information technology tools, it can activate the stylized inference model of mathematical induction to demonstrate its vivid and lively existence Form, to stimulate students interest in learning mathematics .A pre-lesson guiding sense of the United States this lesson as an experimental package of e-schoolbag project, before class to students released a mathematical induction of the scene material library. Principle, analysis of physical education reported the principle of number, analysis of the principle of troop march secret password, using the principle of mathematical induction to help teachers design a classroom to ask questions to all students in the operation method.The central idea of mathematical induction is: Verify and
