所谓数学思想是指对数学事实与理论经过概括后产生的本质认识,可以说数学思想就是数学的精髓。因此在实际教学中渗透数学思想能够帮助学生更好地学习数学。本文主要是对在初中数学中渗透数学思想方法的教学策略进行了研究。一、方程和函数思想在教学中的渗透所谓方程思想是指从问题的数量关系入手,运用数学语言将问题中的条件转化为数学模型(方程、不等式、或方程与不等式的混合组),然后通过解方程(组)或不等式
The so-called mathematical thinking refers to the mathematics facts and theories after the summary of the resulting understanding of the nature, it can be said that mathematical thinking is the essence of mathematics. So in the actual teaching to penetrate mathematical thinking can help students learn mathematics better. This article mainly studies the teaching tactics of infiltrating mathematics thoughts and methods in junior high school mathematics. First, the infiltration of equations and function ideas in teaching The so-called equation of thinking refers to the relationship between the number of questions from the start, the use of mathematical language to the conditions of the problem into a mathematical model (equations, inequalities, or mixed equations and inequalities), and then By solving equations (groups) or inequalities
