Teachers' professional titles rank from low to high as teaching assistant, lecturer, associate professor and professor.
A teaching assistant refers to a position that assists teachers in teaching in colleges and universities, primary and secondary schools. Usually, teaching assistants come from graduates in the same field, and some are part-time graduate students in master's or doctoral programs, and some are external. In some schools, you must have worked as a teaching assistant before you can be promoted to lecturer, professor and associate professor.
In universities in Chinese mainland, teaching assistants are the lowest-ranking titles among university teachers. Generally speaking, if a master's degree holder gets a position in a university, his first title is teaching assistant.
Generally speaking, the work of teaching assistants is to guide the coursework, correct students' homework, be on duty in the department office and supervise the work. In classes with a large number of students, teachers will be assisted in taking experimental classes or internship classes.
Teaching assistants are actually a bridge between professors and students, which plays a good role in communication. Not only should the professor's teaching ideas be conveyed to the students, but also the problems encountered by the students should be sorted out and fed back to the professor.
