高三复习教学的主渠道在课堂,课堂教学效率的高低,直接影响教学质量的高低.可见,课堂教学效率问题是一个很值得研究的课题.高三化学复习是对整个中学阶段所学的化学知识进行系统整理,提高综合运用能力、创造能力的过程.高三化学复习一般分为三个阶段,第一阶段是单元的纵向复习,侧重落实基础;第二阶段进行知识内在联系的横向复习,是前期单元复习的升华和深入,把每一个独立的知识系统化、条理化、网络化;第三阶段,查缺补漏,全面掌握《考试说明》中列出的全部 The main channel for the review of teaching in the third year of high school, the level of classroom teaching efficiency, a direct impact on the level of teaching quality can be seen that the issue of classroom teaching efficiency is a very worthwhile study of the chemical junior high school chemistry review is learned System consolidation, improve the comprehensive ability to use to create the capacity of the high school chemistry review generally divided into three phases, the first phase is the longitudinal review of the unit, focusing on the implementation of the foundation; the second phase of the knowledge of the horizontal relationship between the review, is the early unit Review of the sublimation and in-depth, each independent knowledge systematized, organized and networked; the third stage, check the lack of trapping, a comprehensive grasp of the “test description” listed in all
