A new type of ammeter was developed which indicates the measured current by the movement of a spot of light and the voltage by the color of the spot. Since this tool can make students feel as if they are observing a visual image of electricity, it is easy to prepare schematic explanations on electric circuits that match the students' observations. From such a viewpoint we used a restaurant model with this ammeter in a trial lesson for junior high school students, and found that such a combination is more effective to make them recognize the difference between current and voltage than explanations using ordinary fluid-flow models.The possibility of using clamp-on ammeters was also investigated for educational purposes. It was made clear that clamp-on ammeters can be used in science classes in elementary school as well as in junior high school, and that they may help students to learn the difference between current and voltage.

开发了一种新型的电流表，表明通过光点的运动和通过斑点的颜色的电压移动所测量的电流。由于此工具可以使学生感觉好像正在观察电视的视觉图像，因此很容易准备在与学生观察的电路上进行示意性解释。从这种角度来看，我们在初中学生的试验课程中使用了与此电流表的餐厅模型，并发现这种组合比使用普通的流体流量模型更有效地认识到当前和电压之间的差异。还研究了用于教育目的的可能性。很明显，可以在小学和初中的科学课上使用夹具，并且可以帮助学生学习当前和电压之间的区别。
