(一)初中一年级是否必需再学习算术? 中学数学习惯上都是从学习算术开始的,但是在新旧教学制度中,初中算术课程的设置,在性质上却有着根本的区别。解放以前,小学算术学习的内容很多,初中算术事实上只是把小学学过的东西重复一遍,在习题上予以加深,很大的精力是放在教会学生解一些不切实际的难题。解放后,我们学习了苏联先进经验,对此作了根本的改变,使中小学的算术作了具体的分工:在小学算术中重点放在整数的学习,而分数、小数、百分数只学习一些初步知识;在中学算术中,对整数是在复习
(1) Is it necessary to study arithmetic in the first grade of junior high school? The habit of mathematics in middle school mathematics starts with the study of arithmetic. However, in the old and new teaching systems, the setting of the junior high school arithmetic course is fundamentally different in nature. Before the liberation, there were many contents of elementary school mathematics learning. In fact, junior high school mathematics only repeated the things learned in primary school and deepened the exercises. It was a great effort to teach students to solve some unrealistic problems. After the liberation, we learned advanced experience of the Soviet Union and made fundamental changes to it. We have made the mathematics of primary and secondary schools a specific division of labor: In primary school arithmetic, we focus on integer learning, while fractions, decimals, and percentages only learn some preliminary Knowledge; In middle school arithmetic, the integers are in review
