在实际教学中常感到苦恼的一个问题是学生的记忆问题,由于中专数学课的内容多、系统性差、讲授的速度快,而重复联系的机会少,因而学过的内容容易遗忘,许多学生由于没有恰当的记忆方法致使许多学过的知识(甚至是相当重要的知识)随时间的迁移而过快地忘掉了。迫使我们在上新课时,还得补充必要的旧课,从而冲淡了知识的学习,形成了一种恶性循环,要想提高学生的学习 One of the problems often encountered in practical teaching is the memory problem of students. Because secondary school mathematics lessons have many contents, poor systematization, high teaching speed, and few opportunities for repetitive contact, the content learned is easily forgotten. Without appropriate methods of memory, many learned (and even rather important) knowledge has been forgotten too quickly over time. Forcing us to add the necessary old lessons in the new class so as to dilute the learning of knowledge and form a vicious cycle in which students’ learning needs to be enhanced
