我是一名教学多年的数学老师,对旧教材的体系了如指掌,教学中能很好地把握教材中的知识点、难点、重点,对怎样突破难点与重点,自己都有了一定的心得和经验.如今,经过四年的新教材教学,对比新旧教材,感慨颇多,新教材旨在加强生活数学的教学,避免复杂的计算,但新教材教学也给社会带来了不少的问题.以下几个方面使我们一线的教师感到困惑. I am a mathematics teacher who has taught for many years and is familiar with the system of old teaching materials. In teaching, I can master the knowledge, difficulties, and priorities of the teaching materials. I have some experience and experience on how to break through difficulties and priorities. Nowadays, after four years of teaching of new textbooks, there is a lot of emotion in comparing old and new textbooks. The new textbook aims to strengthen the teaching of life mathematics and avoid complex calculations. However, the teaching of new textbooks has also brought a lot of problems to the society. Several aspects puzzled our frontline teachers.
