在实验复习时,如果仍采用新授课的方法,将实验目的、原理、器材、步骤、数据处理、误差分析等内容重新讲一遍,效果往往并不理想.一是因为旧话重提,激发不起学生听课的兴趣;二是因为讲授内容面面俱到,不便于学生有重点的理解和记忆;三是因为讲的时间多,练的时间就少,当还没有成套的系列练习题时,对各知识点和操作要点常有重练和漏练的现象,学生解答实验习题的能力得不到应有的提高. 鉴于以上复习方法的弊病,两年来,我对实验复习方法做了如下三方面的尝试: 一、讲授内容要点化.即将实验内容中的重点、难点和关键,进行要点式总结,使知识浓缩,其中对操作要点可编成口诀.在复习讲授时,学生感到有新 During the review of the experiment, if the method of new teaching is still adopted, the purpose, principle, equipment, steps, data processing, error analysis, etc. of the experiment will be repeated once again. The effect is often not ideal. The first is because the old words are revisited, and the excitation is not The interest of students in class is the second reason for the fact that the teaching content is all-embracing, and it is inconvenient for students to have important understanding and memory. Third, because there is more time for speaking and less time for practice, when there is no complete set of exercises, the knowledge The points and operating points often suffer from the phenomenon of heavy training and leakage. The students’ ability to solve the experimental exercises is not properly improved. In view of the shortcomings of the above review methods, I have tried the following three aspects of the experimental review method in the past two years. : First, the content of lectures will be focused. The key points, difficulties, and keys in the experimental content will be summarized. The summary of points will be made to enrich the knowledge. The operation points can be edited into words. During the refresher teaching, the students feel that they are new.
