Research on development of teaching materials for the technological field of the technology and industrial arts course in junior high school in consideration of the new courses of study

开始为2002财政年度执行的初中课程技术和工艺美术课程的技术领域编写新教材。这些新教材是一台柱塞式注塑机和一部处理塑料的视频。注塑机是一种教学工具，视频是一种介绍塑料材料加工方法和废弃塑料的教学工具。在开发时，我们考虑成为一台学生可以安全轻松操作的注塑机，以便更容易地了解塑料注射成型方法。此外，为了便于所研制的注塑机的实际应用，还对注塑成型条件进行了实验。简单的金属模具被提出，最初被认为制造起来很困难。由DV非线性编辑制作的视频涉及塑料材料和废弃的塑料加工方法。视频显示，使用开发的塑料注塑机和金属模具可以轻松制造塑料注射成型产品，学生可以通过使用该机器体验塑料产品的制造方法。编写这些视频教材对教师特别有用，因为编写这些教材的目的是使教师能够在课堂上使用这些教材。该视频还考虑到该地区的实际情况，以达到现实的内容。

The development of a new teaching materials were started for the technological field of the technology and industrial arts course of the junior high school course of study executed in the 2002 fiscal year. These new teaching materials are a plunger type plastic injection molding machine and a video dealing with plastic. The injection molding machine is a teaching tool, and the video is a teaching tool which introduces the processing method of a plastic material and abandonment plastic.When developing, we considered becoming an injection molding machine which students could operate safely and easily in order to understand the plastic injection molding method easily. In addition, experiments concerning injection molding conditions were done to facilitate the practical use of the developed injection molding machine. Simple metal molds were proposed, the manufacture of which initially been assumed to be difficult. The video manufactured by DV non-linear edit deals with plastic materials and an abandoned plastic processing method.It was shown that plastic injection molding goods are able to be manufactured easily by using the developed plastic injection molding machine and metal molds, and that students can experience the manufacturing method of a plastic product by using this machine. The video teaching materials are developed useful for teachers in particular because they were developed with aim that teachers would be able to use them in the classroom this video also takes into account the realities in the region in order to achieve a realistic content.
