近几年的物理高考试题中，电学设计性实验绝大 多数考查电阻测量原理和方法。其情景新颖，以学过 的实验为依据，注重对其思想、方法和技能的迁移和 拓展；注重考查了学生的基本实验能力、创新能力和 自主探究能力。而考生往往生搬硬套，导致大量失 分，在此，笔者通过几个高考题的分析，帮助考生开阔 思路，提高解答设计实验题的能力。

In the physics examination questions in recent years, most of the electrical design experiments have examined the principles and methods of resistance measurement. Its novel situation is based on the experiments it has learned and focuses on the migration and development of its ideas, methods and skills. It focuses on examining students’ basic experimental abilities, their ability to innovate, and their ability to explore independently. Candidates are often hard-working, leading to a large number of points. Here, the author analyzes several college entrance examination questions to help candidates broaden their thinking and improve their ability to design experimental questions.
