The aim of research is explain that how the SEIKATUKA subject has practiced it and how the elementary school teacher has accepted it when it has been established from their life histories. The research cooperator 'A teacher' have made own educational philosophy that teachers, parents and children cooperate each other. The philosophy has made by the study in a teacher union. The philosophy is a core for 'A teacher' and is power to get over the various education reform (ex. New Liberalism reform in recent year). The SEIKATUKA subject isn't exception. But this research cleared that because the policy of SEIKATUKA is vague and wavelike education reforms has done, SEIKATUKA has been become a mere pleasure and a mere fa?ade, while SEIKATUKA has been introduced with the brightness. 'SOUGOUTEKINA GAKUSYUNO JIKAN' overlap SEIKATUKA, but 'SOUGOUTEKINA GAKUSYUUNO JIKAN' may go the same dangerous way like SEIKATUKA. To stop the dangerous before happens, we need to accept a good lesson severly.
