While ocean education in elementary and junior high school can be taught through standardized content and methods, in senior high school the class must have meaning for the development of students through bringing out their curiosity and interest in the ocean, and also be readily accepted in the school environment by, for example, being useful for entrance exams for higher education. Here I will propose model curriculums on ocean education in the hopes that new efforts on ocean education will also increase in “general course” (Futsuuka) senior high schools.
