本文以简与繁的辩证观点来分析中学代数知识体系中各部分内容之间的联系,和部分内容各个单元之间的联系,并探讨如何利用这种联系有效地运用数学知识解决问题。以简单性原理指导解题,用“由繁归简”的方法设计教学,旨在培养学生能以“由繁到简”的思维模式提高解题能力,提高学生学习数学的热情和兴趣。 This article uses the dialectical view of simplicity and complexity to analyze the connection between the various parts of the algebraic knowledge system in the middle school and the relations between the various elements of the content in the middle school and discusses how to make use of this connection to solve the problem effectively with mathematical knowledge. The principle of simplicity is used to guide the solution of problems and the design of teaching is made of the method of “exaggeration to simple”, so as to train students to improve their ability to solve problems and improve students’ enthusiasm for learning mathematics in the mode of thinking “from complexity to simplicity” And interest.
