Development of Teaching Materials for Energy Transform based onElectromagnetic Induction

在本研究中，我们提出了四种学习电磁感应的教材。这些教材包括：手工制作的电流互感器、手动型交流发电机、顶压式电机和发电机、非接触式馈电灯。这些教材具有学生自己创作的特点。学生通过自己制作的教材学习能量转换。结果表明，该方法具有较高的学习效果。

In this study, we proposed four teaching materials to learn electromagnetic induction. These teaching materials are as follows: handmade current transformer, hand drive AC generator, top-formed motor and generator, and non-contact feeding light. These teaching materials have the characteristic properties that students create by themselves. Students learn energy conversion with their teaching materials which they made. As a result, high learning result is expected for this method.
