“代数式、方程”是中学代数的第一个项目。在进行这一项目的教学之前,教师首先分析一下中学代数的主要内容,以及代数教学中应注意的某些特点,是十分必要的。因为只有明确了这些问题,教学中才能掌握教材的主要精神,有计划地进行教学工作,全面地达到教学目的。本文将首先就中学代数教学中的一般问题作扼要的分析,然后在此基础上来分析“代数式、方程”这一章的教材,并提出一些教学意见,供教学中的参考。§1 中学代数教学的一般问题 1.中学代数教学的主要内容教师在开始教代数时首先碰到的一个问题是这个科目的内容究竟是些什么。企图象几何那样给中学里所学习的代数这一课程下个明确的定义是困难的。代数,它作为现代数学科学的一个重要分支,是关于给出
“Algebraic equations” is the first item of algebra in middle school. Before carrying out the teaching of this project, it is necessary for teachers to first analyze the main content of algebra in middle school and some of the features that should be noted in algebra teaching. Because only these issues are clarified, the teaching can master the main spirit of the teaching materials, carry out teaching work in a planned manner, and fully achieve the purpose of teaching. This article will begin with a brief analysis of the general problems in the teaching of algebra in middle school, and then on this basis to analyze the “algebraic, equations” chapter of the teaching materials, and put forward some teaching advice for reference in teaching. §1 General Problems of Algebra Teaching in Middle School 1. The Main Content of Algebra Teaching in Middle School One of the first questions teachers encountered when they began to teach algebra was what the content of this subject was. It is difficult to define the course of algebra, which is learned in secondary schools, as the image geometry. Algebra, which is an important branch of modern mathematics, is about giving
