问题是数学的心脏,数学的真正组成部分是问题和解.问题是思维和探索的源泉,是联系新旧知识的桥梁,学生的科学知识与学习能力就是在不断发现问题并解决问题的过程中成长和发展的.在传统的教学中,数学问题设计无非是照本宣科,生搬硬套,缺少对问题的设问与变式,激发不了学生的兴趣,让学生感到索然无味,造成低效教学.本文针对初中数学教学,介绍“点线式”问题结构设计,这一方法能让学生感悟到数学问题之间是相互联系,相互 The problem is the heart of mathematics, the real part of mathematics is the problem reconciliation.The problem is the source of thinking and exploration, is a bridge between old and new knowledge, students’ scientific knowledge and ability to learn is in the process of constant problem finding and problem solving Development in the traditional teaching, mathematical problem design is nothing more than the propaganda, mechanically, lack of questions and variations on the problem, can not stimulate students’ interest, so that students feel boring, resulting in inefficient teaching.This article aimed at junior high school mathematics teaching , Introduced “Dotted ” problem structure design, this method allows students to realize that mathematical problems are interrelated, mutual
