What does teaching assistant mean?

The lowest level of a university teacher's professional title.

The duty of a teaching assistant is mainly to do some auxiliary work with the teacher, such as correcting students' homework and answering students' questions. During the experiment, it is necessary to debug the experimental instruments and check the experimental report. Teaching assistants are the lowest in university titles and cannot teach alone. They need to accumulate experience through auxiliary work in order to improve their professional titles.

In colleges and universities, the teaching assistants of departments are all graduate students of their own majors, who are responsible for answering questions regularly, feeding back students' questions and correcting homework. Teaching assistants need to contact teachers and students to ensure smooth communication between teachers and students, which is conducive to establishing a better teaching environment.
