Attempts at Continuing Annual Series of Experiment and Manufacturing Workshop on the Subject of Electrical Engineering

To prevent that younger people avoid science, we have given annual series of experiment and manufacturing workshop on the subjects of electrical and electronic engineering, as the activities for contribution to the community, since 2008. In order to continue the annual series, the educational tools and materials have been improved continuously in all of the workshop. As the results, our attempts provided systematic education of scientific literacy for many participants (total number 2,000 or more), especially for the repeaters, and they were composed of several age groups, students under junior high school, parents of the students, and elder people. At the same time, they got mutual communications on science and technology. This paper reports some results of educational effect and effectiveness of our attempts.
