八五年高考物理试题第三大题的第二题,是一道用万用表欧姆档测试电阻阻值大小的实际操作题,要求学生在卷面上将测试步骤顺序填写出来。十分清楚,本题是考察学生使用万用表解决实际问题的能力,难度并不大。但是,从本题的回答情况来看,很不理想。一位就读于北京一所全国知名中学的学生十分遗憾地说,这种内容,老师并没有讲过,在实验课上也没有得到接触的机会,他对这一问题真可以说一无所知,并说这一题的分数丢得太不值得了。在另一所北京区级重点中学里,物理老师也只是讲过有关万用表的原理和构造,有关使用问题也同样未曾提及,当然更谈不上学生动手了。由此看来,学生的实验机会和实际动手机会太少,一直是物理教学中的一个十分普遍的现象。
The second question of the third major issue of the 1985 college entrance examination is a practical question about how to test the resistance of a resistance meter with a multimeter ohmmeter. Students are required to fill in the order of test steps on the curled surface. It is very clear that this question examines the ability of students to use multimeters to solve practical problems without any difficulty. However, from the answer to this question, it is not ideal. A student studying in a well-known national high school in Beijing said with regret that this kind of content, which the teacher did not say and did not have access to in the experimental class, was really ignorant of this issue , And said that the score of the question is too worthless. In another district-level key middle school in Beijing, the physics teacher has only talked about the principle and structure of the multimeter. The use of the same is not mentioned, of course, let alone the student hands. Seen in this light, the chances of students experimenting with hands-on activities are too few and have always been a very common phenomenon in physics teaching.
