所谓“精讲”,就是不能“满堂灌”,可以以教师讲评为主,也可以采用双边讲评等形式,围绕教学目标,凸出重点,难点,易错,易混,易漏点。“精讲”集中体现了教师的主导作用,该讲的内容必须讲深讲透,分析过程要强化。例题教学的目的不是为了求得解答结果,而是通过题目的解答过程为学生掌握分析问题,解决问题的方 The so-called “explanation” is that it cannot be “filled with a full house”. It can be judged by the teacher, or it can be used in the form of bilateral assessments. Focusing on the teaching objectives, it highlights key points, difficulties, error-proneness, confusability, and leakage. The “explanation” embodies the leading role of the teacher. The content of the lecture must be thoroughly explained and the analysis process must be strengthened. The purpose of the example teaching is not to obtain the answer result, but to solve the problem by analyzing the problem and solving the problem through the solution process of the topic.
