近年来,图片类电学问答题已成为中考物理的热点题型之一,它要求同学们应用已学过的物理知识来解释日常生活、生产和科学实验中发生的物理现象和过程.它的主要作用有:(1)巩固和加深对已学过的物理概念、原理和定律等物理知识的理解;(2)不断提高同学们的观察能力、逻辑推理能力和书面表达能力;(3)逐步培养同学们灵活运用物理知识来解释各种现象的好习惯,使同学们能够学以致用.那么如何解答好这类题呢?第一,审清题意,理解题目要求我们去解答哪些方面的物理问题;第二,仔细观察图片,找出图片中所能够体现出的相关知识点,即相应的物理概念、规律、原理等;第三,正确解答,答题时要求做到:论点明确、论据充分、条理清楚、答案完整、用词简练恰当;第四,检验答案,检查时应把重点放在解答过程是否按照题意作答,得到的结论是否全面完整.
In recent years, the picture-based electricity quiz has become one of the hot topics in the physics of middle school students. It requires students to apply the physics knowledge they have learned to explain the physical phenomena and processes that occur in daily life, production, and scientific experiments. The functions are: (1) to consolidate and deepen understanding of physical knowledge such as physical concepts, principles, and laws that have been learned; (2) to constantly improve the students’ observation ability, logical reasoning ability, and written expression ability; (3) to gradually cultivate Students use physics knowledge flexibly to explain the good habits of various phenomena, so that students can learn to use. So how to answer these questions? First, to review the meaning of the problem, to understand the subject asked us to answer which aspects of physics Secondly, carefully observe the pictures to find out the relevant knowledge points that can be reflected in the pictures, that is, the corresponding physical concepts, laws, principles, etc.; third, correct answers, and ask for answers when answering questions: the points are clear and the arguments are sufficient. , Clearly organized, the answer is complete, the word concise and appropriate; Fourth, test the answer, the inspection should focus on whether the answer process according to the question to answer, the conclusion is complete and complete.
