在物理教学中,常发现学生在解题时,就题论题,解完题后的深究、探索、小结不够。尤其是选择题,选完答案后,只要与标准答案相符,就认为万事大吉,心满意足。这种学法对熟练掌握知识,培养能力都是有害的。做题的目的,不是简单地把学过的知识套在这道题上,而是要通过解题深化、活化有关基础知识,培养迁移能力,掌握解题的一般方法。 我在教学中注意引导学生深挖习题内涵,采用一题多变,一题多解等方法和学生一起探索习题所涉及的概念、规律、方法、技巧,扩展习题功能,这样一题变
In physics teaching, it is often found that when students solve problems, they have problem topics, and after the completion of the problems, they do not have enough study, exploration, and summary. In particular, the multiple-choice questions, after the answers have been selected, are considered satisfactory if they meet the standard answers. This method of learning is harmful to the mastery of knowledge and ability to cultivate. The purpose of the question is not simply to put the learned knowledge on this subject, but to deepen the problem, activate the relevant basic knowledge, cultivate the ability to migrate, and master the general method of problem solving. In the teaching, I paid attention to guiding students to dig deep into the connotation of the problem, and used a method to change the subject, to use multiple solutions, and to explore the concepts, rules, methods, and techniques involved in the exercises, and to expand the exercises.
