一、缘起教学完“用形如ax±b=c、ax÷b=c、ax±bx=c的方程来解决相关实际问题,并自主探索有关方程的解法”这一内容后,年级组很多老师反映学生能正确地列出解决实际问题的方程,但解方程时犯了很多未曾预见,也从不曾遇见过的新错误。影响学生学习效果的原因何在?怎样才能提高方程教学的实效?二、原因分析1.教材编排特点对学习效果的影响(1)知识点分散。学生学习此内容的知识基础,如“用字母表示数”“等式的 First, the origin of teaching finished ”with such as ax ± b = c, ax ÷ b = c, ax ± bx = c equation to solve the relevant practical problems and to independently explore the solution of the equation “ This content, grade Many teachers in the group reflect that students can correctly formulate equations that solve practical problems, but many new and unexpected mistakes have never been made in solving equations. What causes the effect of student learning? How can we improve the effectiveness of the teaching of the equation? Second, the reasons for analysis 1. The characteristics of the textbook layout on the learning effect (1) knowledge points scattered. Students learn the basics of this content, such as ”Letters“ ”" equation
