First of all, we should know that the interview will go through three stages-structuring, trial presentation and defense, with a total time of 20 minutes. The time allocation of these three parts should be 1:2: 1, that is, structuring for five minutes, trial presentation for ten minutes and defense for five minutes. Of course, it is undeniable that the intermediate link-the trial lecture is the most important. So how do you grasp the most important part?

In fact, the key to a good lecture is to prepare lessons. Teaching interview, the total time of preparing lessons is 20 minutes, during which a short case needs to be completed. Therefore, the lesson plans we write here should be as concise and clear as possible, and the time should be controlled at about ten minutes. Finally, there are ten minutes to sort out ideas and supplement the teaching process.

With the teaching design, how can I show it to the examiner when I speak? In fact, any math class can be regarded as consisting of five parts: introduction-putting forward new knowledge-explaining new knowledge-applying new knowledge. Teaching according to this logic will combine the characteristics of mathematics with students' cognition, and the logic in the teaching process will be clear.

Finally, it should be noted that the form of interview trial lecture is lifeless trial lecture, so we need to learn to simulate and perform, thus reflecting the subjectivity of students. For example, set up questioning sessions and group discussion sessions.
