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

本课题从技术与自然相结合的观点出发，将从河岸向河流中心突出的堤岸状建筑物“水濑”作为技术教育的教材进行研究。研究结果如下：通过对河流治理中的传统建筑方法“水濑”本身的文献调查，以及对水濑建筑物中使用的技术的历史调查，并在实地考察的基础上，从技术融入自然的角度，提出了技术教育的教学计划。通过水力学模型实验，发现学生可以很容易地理解自来水的基本结构和自来水的效果。通过学生们的各种调查活动以及对水濑的介绍，他们开始关注使用天然材料的建筑，并通过比较水濑结构的河道和混凝土覆盖的河道，从技术角度关注对自然柔和的方法。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.
