Abstract
Opposing the home economics only for girls, this study examined the factors that enable the practice of coeducational home economics on the national curriculum and the theory of coeducational home economics in Nagano prefecture in 1970s. The results are as follows. 1. Several teachers who had hoped the practice of coeducational home economics began to study coeducational home economics and exchanged their ideas and class practices. 2. The Education and Culture Meeting in Nagano Prefecture which most of high school teachers belonged and Nagano Prefecture Senior High School Teachers and Staff Union held the three fundamental rules in high school and supported coeducational home economics. 3. The theory of coeducational home economics was first considered as the subject of "GENERAL SKILLS" and next as "LIFE SCIENCE." Home economics teachers who positively pushed for the coeducational home economics wrote the materials for coeducational home economics. 4. The facts that home economics teachers had their study meetings, wrote a textbook of coeducational home economics, and studied the theory of coeducational home economics were similar to the case in Kyoto Prefecture.
