在数学教学中运用迁移规律搞好旧知识向新知识的过渡、形象思维向抽象逻辑思维过渡,这是提高教学质量的途径之一。教学实践中如何引导学生实现这两个过渡,现将教法体会介绍如下。一、旧知识向新知识的过渡数学知识是有系统、互相联系的。在一系列知识之间,往往前面知识是后面知识的基础,后面知识是前面知识的发展,所以,学习后次复习前次,以旧引新是必要的。然而新知识既 It is one of the ways to improve the quality of teaching by using the law of migration in mathematics teaching to improve the transition from old knowledge to new knowledge and from image thinking to abstract logical thinking. How to guide students in teaching practice to achieve these two transitions, teaching methods are now introduced as follows. First, the transition from old knowledge to new knowledge Mathematical knowledge is systematic and interrelated. In a series of knowledge, often the front of the knowledge is the basis of the latter knowledge, the latter knowledge is the development of the previous knowledge, so learning the last review, the old introduction is necessary. However, new knowledge is both
