物理学是一门以实验为基础的学科.研究物理实验,不仅能帮助学生进一步掌握有关的实验操作程序和规则,还能帮助学生加深对物理概念和规律的理解.在初中阶段,要求学生掌握各种仪器的正确使用方法,体会物理实验的思路和方法,提高观察、实验能力和应用物理知识解决实际问题的能力.综观近年来的物理中考试题,有关实验的命题在形式和内容上发生了较大的变化,特别是设计型实验题的比重逐年增大,加大了对学生实验能力考查的力度.所谓设计型实验题,是指以基本实验原理为基础,要求学生应用基本的测量仪器自行设计实验方 Physics is an experiment-based discipline.Researching physics experiments not only helps students to further understand the relevant experimental procedures and rules, but also helps students to deepen their understanding of the concepts and laws of physics.In the junior middle school, students are required to master The correct use of various instruments, understand the ideas and methods of physical experiments to improve the ability of observation, experimental ability and the application of physical knowledge to solve practical problems.In view of recent physical examination questions, the proposition about the experiment took place in the form and content Large changes, especially the proportion of design-based experiment increased year by year, increased the test of students ability to test the so-called design of experimental questions, is based on the basic experimental principle, requires students to use the basic measurement instruments Design side of the experiment
