I don't know if you mean secondary school, higher vocational school, higher vocational school or undergraduate course.
In fact, there are many secondary schools for children's English, all of which are derived from preschool education. The difference is that there are more English classes. Preschool education is a small discipline with strong professionalism, involving multidisciplinary knowledge such as pedagogy and psychology.
Taking the undergraduate course as an example, the basic courses of undergraduate course should be pedagogy, psychology, education statistics, China education history, foreign education history, educational psychology, developmental psychology, etc. Public courses are similar all over the country, mainly including philosophy, thinking, college foreign languages (non-preschool English) and physical education. Elective courses are generally optional. There are two doors, no upper limit.
I want to study specialized courses, such as professional English, preschool education, preschool psychology, preschool hygiene, preschool education research, preschool curriculum design and teaching methods (different school textbooks have different names), educational regulations, music theory, dance, keyboard, art, and so on. I can't remember it all at the moment.
I hope I can help you.
