Abstract
This paper analyses and examines Fuji Goyosaku’s research process for teaching aids for both manual arts and science, and reveals the following three points. First, Fuji developed manual arts teaching aids compliant with science textbooks. Originally, experiment equipment, toys for demonstrating the laws of physics, and other aids for teaching science did exist, but textbooks were rarely referred to. Second, he researched teaching aids in education for young children. Originally, manual arts teaching aids related to science were often assigned from the upper grades of ordinary elementary school to higher elementary school, as well as in middle school, but Fuji conducted research on teaching aids that kindergarten children could handle with their level of skill. Third, Fuji proposed educational methods with the aim of getting work in industry. He went beyond the category of school education to practice courses for nurturing product development skills in industry.
