在初中化学教学中,发现有的学生疲于“题海战术”,结果浪费精力和时间,事倍功半,原因主要是只重视解题的数量和结果,不重视解题的思路、方法和题型的变化。本人认为应指导学生解题后思考、多角度分析解题思路,继而变题,挖掘引申,让学生思考讨论,探导多种解题方法,总结规律,提高
In junior high school chemistry teaching, some students were found to be tired of “sea tactics”, resulting in a waste of energy and time, and less effective. The main reason was to only pay attention to the number and results of problem solving, and did not attach importance to problem solving ideas, methods, and types of questions. Variety. I believe that students should be instructed to think after thinking about the problem and analyze the problem-solving ideas from multiple angles. Then they can change the subject and excavate the ideas so that students can think and discuss, explore a variety of problem-solving methods, and sum up the laws.
