化学学科知识点多而散,不少学生在学习时往往以机械记忆为主,这样一方面复习效果不理想,另一方面又导致学生对化学学习兴趣下降,甚至产生畏惧心理。笔者总结多年教学经验,结合化学学科特点,对相关知识进行梳理和整合,编制成专题引导学生复习,这样既利于学生系统地掌握有关 Many chemical knowledge points scattered, many students are often mechanical memory-based learning, so that the review is not satisfactory on the one hand, on the other hand also led to the decline in students interest in chemistry, or even produce fear. The author summarizes years of teaching experience, combined with the characteristics of chemistry, the relevant knowledge to sort out and integrate the preparation of topics to guide students to review, this will help students to systematically grasp the relevant
