通过实践,我们觉得“讲—练—考—评”循环加深是化学总复习中行之有效的方法,现作简要介绍。 一、讲: 总复习前,先进行摸底考试,了解学生在基础知识和基本技能方面存在的问题,做到心中有数,辅导时对症下药,分专题讲解。复习不是讲新课,也不等于重讲,在复习中将所学化学知识通过分析对比,找出物质间的共性和个性,从
Through practice, we feel that the “speaking-training-testing-evaluation” cycle is an effective method for reviewing the total chemistry, and is now briefly introduced. First, talk: Before the general review, first to carry out a test, to understand the students in the basic knowledge and basic skills exist, know what to do, counseling when the right medicine, sub-topics to explain. The review is not about new classes, nor is it equal to revisiting. In the review, the knowledge of the learned chemistry is analyzed and compared to find out the commonness and personality among the substances.
