His main job is

Be responsible for warming up before class. You know, if a training institution like New Oriental organizes lectures in various schools, it must cooperate with local people. The first job of the teaching assistant is to help the lecturer to enliven the atmosphere on the spot, and there are some publicity materials to prepare for the PPT of the speech.

In class, I actively cooperate with the lecturer to complete the teaching activities. For example, read the words aloud, or have a conversation with the lecturer.

After class, the teaching assistant should help the lecturer check the assigned tasks and urge the students to complete the teaching tasks.

That's about it.

According to the actual situation, you may be assigned something extra.

But that's all.

A teaching assistant is a lecturer's assistant. It won't be difficult, but it also needs strength! I hope you succeed!
