Practice Study of the Creative Teaching Materials Using New Material and New Energy for Junior High School Technology and Manufacturing Classes

在这项研究中，我们开发了形状存储器合金发动机汽车和被动行走玩具作为一种新的材料和新的能量教学材料。本研究的主要目的是找到在初级高中引入教学材料的可能性，实际上是一门技术教育课程。在SMA发动机汽车中，形状存储器合金和脉冲被用作汽车的主要主移动。“引擎可以旋转使用形状的内存合金可以直接进入形状的属性，因为它得到了在热水中。”最具特色的部分是发动机。为了使上脉冲和下脉冲之间的温度差异如可能的那样大，引擎部分从底盘中脱落约45度。因为热水和房间温度之间的温度差异是使发动机像可能快一样旋转的最重要的因素。被动行走玩具走在温和的斜坡上，使重力力和平衡力的稳定性。为了使用玩具作为教学材料，我们测量了它行走的周期，并分析了运动。然后，它走路中各种元素的影响是有必要的，找到作为教学材料的可能性，发动机汽车的玩具实际上是在初级高中的技术教育课程中引入的，作为实际教学。通过制造，学生可以通过使用工具的困难和乐趣的经验，不仅是学习制造的方法，而且也是金属特性、使用工具的方法及其名称的知识。

In this research, we developed the shape memory alloy engine car and passive walking toy as a new material and new energy teaching material. The main purpose of this study is to find the possibility of introducing the teaching material in a junior high school as a class of technology education actually.In the SMA engine car, shape memory alloy and pulleys are used as a main prime mover of the car. The engine can rotate using the properties that shape memory alloy can turn into straight-shaped as it gets in a hot water. The most characteristic part is the engine. To make the temperature difference between upper and lower pulleys as much as possible, the engine part is leaned about 45゜ from a chassis. Because the temperature difference between hot water and room temperature is the most important to make the engine rotate as fast as possible.The passive walking toy walks down a gentle slope due to the gravity force and the instability of equilibrium. For using the toy as a teaching material, we measured the cycle period of its walking, and analyzed the motion. And then, the influence of various elements in its walking was considered.To find the possibility as a teaching material, the engine car ans toy were actually introduced in the class of technology education in junior high school as a practical teaching. Through the manufacture, the students can get through the experience of difficulty and joy to use tools and learn not only the way of manufacturing it but also the knowledge of a metal properties, the way of using tools and its names.
