从教多年来,我们常常听到数学老师抱怨:数学越来越不好教了。学生学不好数学就是因为数学理论性太强,不能像语言学科那样通过读、写、练,加强记忆就能考高分;也不像音乐课、体育课那样诱惑力强易于记忆。我一直在思索,数学中的记忆真的那么难吗?对于理性数学知识,我们是不是也要尝试着进 After years of teaching, we often hear math teachers complain that mathematics is getting harder to teach. Students learn mathematics is not good because mathematics theory is too strong, can not like reading, writing, practicing, strengthening memory will be able to test a high score like the language discipline; nor as music class, physical education class as tempting and easy to remember. I’ve been wondering, is the memory of mathematics really so difficult? For rational mathematical knowledge, we also have to try
