根据中学教学数学大纲(草案)的规定,在初中二年级第一学期应该讲最简单的方程(按即指一元一次方程),兹对此提出两点说明供教师们参考.1.教学大纲(草案)的代数部分说明中指出:“要在学生已知的算术运算性质的基础上来作解方程演算(按即解方程)”.又在大纲(草案)的单元纲目中指出:“根据算术四则运算的定义与性质解最简单的方程,……”.所谓算术四则的定义,即加法定
According to the provisions of the Teaching Mathematics Outline (Draft) for secondary schools, the simplest equation in the first semester of the second grade of junior high school should be described (that is, one-time equation). Two explanations are provided for teachers’ reference. 1. Syllabus ( In the algebraic part of the draft, the explanation states: “On the basis of the nature of the arithmetical operations known to the students, the equation calculus is to be solved (the equation is solved immediately).” In the outline of the draft (draft), the unit outlines: The definition and nature of the operation are the simplest equations,...". The definition of the arithmetic four is statutory
