First, you should read the textbook thoroughly, because it is 1 hour after the lottery. In this one hour, in addition to preparing for the trial lecture, I have to hand in my own teaching plan (which lesson). Therefore, it is best to write the lesson plan for each class in advance. A trial lecture is to tell the examiner how to teach, what to say and how to teach. It usually takes about 15 minutes. Of course, it depends on your expressive ability and adaptability, and you have the opportunity to listen to the teacher.
