物理概念和规律是物理知识的核心内容,经分析归纳建立概念,揭示规律,对于消除学生的思维障碍,加深理解物理概念和规律是十分有效的。笔者在本文设置一个题目,目的是通过解题来检验和巩固学习成果。因为通过解题不仅能反映学生掌握知识的程度,同时也考察学生推理、分析、归纳、总结等诸方面的能力。解题不应单纯着眼于运算结果的正确,而更应注重活化课本知识及实际能力的训练。本文试从不同角度给出三种各有特点的解法,以期对学生解题能力的培养有所帮助。
The concept and laws of physics are the core content of physics knowledge. After analysis and induction to establish concepts and reveal laws, it is very effective to eliminate students’ thinking barriers and deepen the understanding of physical concepts and laws. The author has set a topic in this article. The purpose is to examine and consolidate learning outcomes through problem solving. Because solving problems can not only reflect the degree of students’ knowledge, but also examine students’ abilities in reasoning, analysis, induction, and summarization. Problem solving should not focus solely on the correctness of the calculation results, but should also focus on training textbook knowledge and practical ability. This paper tries to give three solutions with different characteristics from different perspectives, in order to help students develop their problem-solving abilities.
