前不久,笔者观摩了一堂应用信息技术的实验教学课“串并联电路”。教师在计算机上模拟用电池组、小灯泡、电键、电流表、电压表、导线等实物连成的电路及实验过程,将电路的通断、电流的路径、灯泡的明暗以及串并联电路电压、电流的特点及关系展示得清清楚楚,非常轻松地突破了教学重难点,学生也十分容易地掌握了各个知识点。课后,学生反映非常好,都说这样的实验课我们看得清、记得牢,考试没问题。但一个学生的话语引起了笔者的深思,他说:“这是电脑做出来的,比这复杂得多的电子游戏都能做出来,做这点还不容易。”有学生对实验结果提出了质疑,我当即与该堂课教师进行了交流与探讨,一致认为用 Not long ago, the author observed a series of parallel teaching of experimental teaching courses using information technology. The teacher simulates the circuit and experiment process using battery packs, small light bulbs, electric keys, ammeters, voltmeters, wires, and other physical objects on the computer. The circuit is turned off, the path of the current, the brightness of the light bulb, and the voltage and current of the series and parallel circuit. The characteristics and relationships are clearly displayed, and it is very easy to break through the difficult points of teaching. Students are also very easy to master the various knowledge points. After the class, the students responded very well. They said that in such an experimental class, we could see clearly and remember it. There was no problem with the exam. But a student’s discourse led to the author’s deep thoughts. He said: “This is what the computer has come up with. This is a much more complicated video game. It is not easy to do this.” Some students put forward the results of the experiment. Questioned, I immediately exchanged and discussed with the class teachers and agreed that
