Prof. Hitoshi Yoshimoto have been looked up great theorist modern general didactics in Japan. And he retired from Hiroshima University in this year (1987). At this point, I have some and unconcrete imaginations or trends about teaching-leatning theories about health and physical education. Already some researcher study his theory and pursue Hitoshi Yoshimoto in the domain of health and physical education.
In this paper, I select and study about Kihaku Saitho, Takeji Hayashi, Atsushi Kobayashi and Kazuhisa Kobayashi, and compare tyeir studying attitudes. They study own practice in common with own theory, but all their theory and practice have not all universality. On my viewpoint, new practice and theory will be constructive as swimming program.
