Teachers' class refers to a kind of colleges and universities in general, not to some majors in particular. Specifically, all majors in normal universities in the past can be regarded as normal majors, including psychology, pedagogy and other majors that are not engaged in teacher work. Now, many normal universities have been changed into comprehensive universities.

Therefore, it is customary to refer to mathematics, physics, chemistry, Chinese, foreign languages, politics, physical education and other disciplines related to primary and secondary education in normal universities as normal education. Similarly, the basic disciplines of educational scientific research in primary and secondary schools, such as pedagogy and psychology, are also called normal majors.
