This study developed a compact material testing machine which can be used in the lecture room for the education of the material strength. The developed testing machine includes a tension-compression testing machine, computer systems which calculate the input signals as stress and strain data and show the graphic of its data and microscopes in order to observe the macroscopic and microscopic deformation and fracture of materials.This machine was designed so as to be possible to observe the material deformation macro and microscopically at the same time. Thus, the students understand the complex material deformation and fracture easier and also take interest in the material strength. The developed machine hepls to understand the material deformation and fracture intuitively and definitely even with no professional knowledge, so it can be used for the lectures such as a open campus for children and aged persons. This study confirmed that the lecture using the testing machine appeals to the students for increase their interest in the material strength much. However, in order to apply the developed testing machine to the regular lecture, it was considered that the improvements of teaching materials and visual programs are needed and also examine the response of students and the educative results thorough the additional lectures. Then, the new method of the education of material strength using the material testing machine will be developed by the feedback from the above results.

本研究开发了一种小型的材料试验机，可用于教室里的材料强度教学。所研制的试验机包括拉压试验机、计算输入信号的应力应变数据并显示其数据图形的计算机系统和观察材料宏观和微观变形和断裂的显微镜系统，该试验机的设计是为了能够同时观察材料的宏观和微观变形和断裂。使学生更容易理解复杂的材料变形和断裂，并对材料强度产生兴趣。所开发的机器即使在没有专业知识的情况下也能直观、明确地了解材料的变形和断裂，因此可以用于儿童和老年人的开放校园等讲座。本研究证实，使用测试机的讲座吸引学生，以增加他们的兴趣，在材料的强度很大。然而，为了将开发的测试机应用于常规讲座，人们认为需要改进教材和可视化程序，并通过额外的讲座检查学生的反应和教育效果。然后，根据上述结果的反馈，开发出利用材料试验机进行材料强度教学的新方法。
