How can students ignore the discipline I set for them? Anger! !

The students you said are rebellious, and you can't achieve your goal with punishment. Punishment can only aggravate their dislike of you. Try to think from their perspective, get familiar with them on some issues, give encouragement, and let them taste the taste of honor for the first time. Then at the right time and occasion, tell them that the teacher needs some coherence in his lectures and encourage him to speak, but at the right time.

In fact, being able to blend in with children is the real success, especially you, a child of teaching age.
