电学实验题是物理高考的必考题型,自2007年实行新课标以来,高考题中很少出现与考纲所列实验一模一样的题目,但大多数来源于教材,只是在此基础上稍作变化。高考实验的考查更侧重于对基本实验的变化、组合和延伸。对这样的题目,学生往往是对教材中的实验掌握得很熟练,但仍然感觉无从下手。尤其是设计性实验,更是束手无策。究其原因,往往是学生只认识到一些仪器的表面用途,而对器材的一些拓展应用缺乏灵活的变通能力。
Since the implementation of the new curriculum standard in 2007, there are few problems in the entrance exams that are exactly the same as the ones listed in the test syllabus, but most of them come from the textbooks, and only make some changes based on this . Examination of the college entrance examination more focused on the basic experimental changes, combination and extension. For such topics, students tend to master the experiment in the textbook, but still feel unable to start. In particular, design experiments, it is helpless. The reason is often that students only recognize the surface usage of some instruments and lack flexibility for some of their applications.
