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.

研制了一种新型的电流表，它用光点的运动来指示被测电流，用光点的颜色来指示电压。由于该工具可以让学生感觉到他们正在观察电的视觉图像，因此很容易准备与学生观察相匹配的电路示意图。从这一观点出发，我们在初中生的实验课上使用了这种电流表和餐馆模型，发现这种组合比使用普通流体模型更有效地让他们认识到电流和电压之间的差异。此外，还研究了使用钳形电流表的可能性。明确了钳形电流表可以在小学和初中的科学课上使用，它们可以帮助学生学习电流和电压之间的差异。
