中学校における鉛フリーハンダ付け及び回路設計学習の試み

抄録

Environmental regulations such as RoHS are essential considerations in industry, however, it is almost not considered in technology education in secondary schools although the Courses of Study refers the relationship between the technology and both society and the environment. Also, designing an electrical or an electronic circuits in secondary school are very difficult compared to wooden products due to students' limited skills in electricity and difficulties of various parts preparation. In this paper, we report trial results for lead-free soldering and “design & production” study of an LED light in secondary schools. Both trials are carried out successfully so that these can be applied to standard learning materials in technology education.
