Introduce yourself: name, native place, age, school of graduation, why you want to be a teacher, etc. Prepare 1-2 minutes. It's not too complicated.

Class: Think about how your teacher attends class. The time is about 5-20 minutes. It mainly examines your teaching mode, language expression ability, affinity, arguments, emergency treatment (such as how you solve a problem that stumbles you), knowledge reserve and so on.

Lecture: Let you talk about how you took this class, such as introduction, teaching objectives, important and difficult points, homework and so on. How do you connect these parts and tell them to the students?
