我们认为,初中数学的教学,主要要加强基础,越是讲“知识爆炸”和提出培养创造型人才,越是要注意抓基本,打好基础。初一代数第一章有理数,是紧接着小学算术学习的,因此要注意与小学阶段教学的衔接,有理数运算实际上就是算术里的数的运算加上 We believe that the teaching of junior high school mathematics mainly needs to strengthen the foundation. The more we talk about the “knowledge explosion” and the proposal to cultivate creative talents, the more we must pay attention to the basics and build the foundation. The first generation of the first chapter of rational numbers, followed by elementary school arithmetic learning, should pay attention to the convergence of teaching with the primary school. The rational number operation is actually the arithmetic operation of the numbers plus
