数学学科不同于其他学科,它不仅要求学生按部就班完成教材基本内容的学习,还要求学生能够基于教材内容发散思维,举一反三,做到触类旁通。如何促进学生发散思维,提高学生应用题解题能力?笔者从小学数学教学的实践经验出发,就分析对比、辨别题目易混因素,一题多解、研究数量关系,扩展过程、揭示逻辑规律三方面入手,介绍一下在小学数学应用题解题方面的教学心得和体会。
Mathematics is different from other disciplines, it not only requires students to step by step to complete the basic content of teaching materials, but also requires students to divergent thinking based on the content of teaching materials, to sum up one another, so that analogy bypassed. How to promote students ’divergent thinking and improve students’ abilities to solve problem-solving problems? Based on the practical experience of math teaching in primary schools, the author analyzes and contrasts, distinguishes the factors that are easily confused with each other, examines the relationship of quantity, expands the process and reveals the law of logic III To start with, introduce the primary school mathematics problem solving teaching experience and experience.
