As a school education, education without punishment is incomplete, unsound and irresponsible. Students certainly need the freedom to live and study, but for middle school students whose rational thinking has not yet been fully formed, excessive freedom will make them do whatever they want, and at the same time they will be at a loss. Without necessary and correct guidance and discipline, students will not really integrate into the existing environment, not to mention "learning to survive". At this time, educational punishment is particularly important. As a class teacher, we should pay attention to the premise of respect and care while punishing, and also pay attention to the principle of punishment.

(1) Prudent punishment principle. Appropriate use of punishment, comprehensive consideration of students' development level in all aspects and complex problem situations.

(2) the principle of pointing to fault. Punishment should always clearly point to the wrong behavior and should not discriminate against the wrong person to avoid the halo effect.

(3) The principle of timeliness and firmness. "Timely" means that the punishment decision should be implemented in time. Doing so is conducive to clearly pointing the punishment at the wrong behavior, not at a person. "Resolutely" means that unless there is something wrong with the punishment itself, once it is implemented, it must be resolutely implemented. Doing so can not only show the firm views of teachers and parents on wrong behavior, but also clearly show the seriousness and authority of punishment itself, so that children can feel the seriousness and inviolability of discipline and social law.

(4) The principle of equal treatment. That is, a unified punishment standard is imposed on those who are bound by all rules. (5) the principle of caring. Refers to the care of the punished person after the punishment is implemented.
