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

2002财年实施的初中课程技术与工艺美术课程的技术领域开始开发新教材。这些新教材是柱塞式塑料注射成型机和塑料处理视频。注塑成型机是一种教学工具，视频是介绍塑料材料和废弃塑料的加工方法的教学工具。在开发过程中，我们考虑成为学生可以安全轻松地操作的注塑成型机，以便轻松了解塑料注塑成型方法。此外，还进行了有关注射成型条件的实验，以便于所开发的注射成型机的实际使用。人们提出了简单的金属模具，最初认为其制造很困难。通过DV非线性编辑制作的视频，展示了塑料原料和废弃的塑料加工方法，通过开发的塑料注射成型机和金属模具，可以方便地制作塑料注射成型制品，并让学生体验塑料制品的制作方法。制作的视频教学材料对教师特别有用，因为制作这些材料的目的是使教师能够在课堂上使用这些材料。

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.
