On the significane of Technology Education from the viewpoing of "Technology integrating itself into nature-suisei-"

这个项目涉及的是一个从河岸向河中心伸出的河岸状结构，从技术融入自然的角度来看，它是技术教育的教材。结果总结如下。通过对河道整治中传统施工方法“水成”本身的文献考察和水成结构技术的历史考察，以及对水成结构的实地考察，从技术与自然相结合的角度提出了技术教育的教学方案。本课程是根据该计划进行的。通过水力学模型的实验，学生可以很容易地理解水的基本结构和水的作用。通过学生们的各种调查活动和对瑞石的介绍，他们通过将瑞石结构所执行的河道与覆盖混凝土的河道进行比较，从技术方面开始关注使用天然材料的施工和对自然柔和的方法。最后，他们可以注意到技术融入自然的观点的重要性。

This project deals with the suisei, a bank-like structure jutting out toward the center of a river from the riverbank, as a teaching material for Technology Education from the viewpoint of the technology integrating itself into nature.Results are summarized as follows.After the investigation by literature on suisei itself which is a traditional method of construction in river improvement, and on the history of technology used in suisei structure, and also after the field work investigation of suisei, a teaching plan for Technology Education is proposed from the viewpoint of the technology integrating itself into nature. The class based on this plan is carried out.It is found that students could easily understand the fundamental structure of suisei and the effect of suisei through the experiment by a model of hydraulics. Through students' various investigative activity and also the presentation about suisei, they became to pay an attention to the construction used the natural materials and on the methods which are soft to nature from the viewpoint of technical aspect by means of comparing the river course executed by suisei structure with the river curse covered with concrete. Finally, they could notice the importance of the viewpoint of the technology integrating itself into nature.
