Including myself, all take the teacher's lectures for granted, so I basically didn't take the initiative to applaud the teacher after class. It's really inappropriate to think about it now. After all, teachers are the people who pass on our knowledge, and they are important people in our lives and deserve our respect. Applauding the teacher after class is an affirmation and encouragement to the teacher, which makes them feel that this class is not in vain, and more knowledge points may be talked about in the next class.
I am a management major myself, but as a college student, I have one more certificate and one more road, so I am also taking various certificates. When taking the teacher qualification exam, every time after class, the teacher who manages us will let us applaud the teacher and thank him for giving us a hard day's class. Seriously, the teacher did a good job. Applauding the teacher after class is to thank him for his affirmation and to encourage him.
In our country, primary school students will stand up and say goodbye to their teachers after class, but they haven't done so since junior high school, and they haven't thanked their teachers for their lectures in any way, especially universities don't care about teachers clapping after class. I think college students in our country should pay more attention to this kind of thing. After all, they should be able to better understand the teacher's difficulties. They must applaud the teacher's efforts after a class and let her feel her sense of accomplishment.
