First of all, there are some basic principles of class management, such as: the principle of encouraging all staff, the principle of independent participation, the principle of combining discipline with training, the principle of rationality, the principle of parallel management, and the principle of coordination. Principles should not be compromised. Teachers who are too gentle will indeed violate principles because they can't bear it, which will lead some students to push their luck and violate class rules.
Secondly, "goodness" and "strictness" should be dialectically unified, which will only make the relationship between teachers and students tense. Combining leniency with severity is the secret of a good class teacher's success, and "being a teacher first, then being a teacher" is the magic weapon of a successful class teacher.
Of course, different class characteristics need different management methods to adapt. In some classes, students need the rule of law, and some may need to be soft. In addition, the evaluation of the success of teacher management can not be compared from only one aspect, and different angles will have different results. Maybe a gentle teacher is not as easy to get grades as a strict teacher. However, judging from the future development of students, it is difficult to tell the outcome. Many students who have graduated for many years often go back to school to visit their gentle teachers. In retrospect, they feel that teachers have the attraction of maternal love when they are at school. For those teachers who are strict and famous for their high grades, memories are sometimes cold.
Therefore, teachers with different personalities, as long as they do it wholeheartedly, will have a shining side. The meaning of success is different from different angles, so the answer to this question is not absolute.
Finally, a gentle class teacher can get twice the result with half the effort by changing the management style in time. They all say that "a dog jumps over the wall and a rabbit eats grass at the edge of the nest." When students who are used to "flexible rule" meet the gentle head teacher who is decisive in battle, the impact of contrast makes students more puzzled and more awed by this gentle head teacher with educational wisdom.
