Private appointment with mischievous students to discuss
What if there are only a few students in the class who are quite 'hard to cooperate with and do not obey? Of course, more individual approaches are needed now. For each case, the teacher needs to come up with a separate way to handle it and to avoid affecting other students in the class, as well as create a comfortable environment for these 'difficult' students to share, instructors can make private appointments and talk directly with those students.
For example, in the class, there are students who often miss class without permission, and do not do homework. If the classroom reminders - both gentle and strict, are not effective, the teacher should contact and talk privately with the pupil to find out the cause of the above situation and from there take remedial measures. Maybe because you feel that the course is not suitable or you can't arrange the time to study. A face-to-face discussion will help the lecturer better understand the cause of the problem instead of blaming the student's laziness or poor knowledge and students will also feel more dedicated to the teacher.
