Disciplining students and cultivating good behavior habits, just like water conservancy, should be "blocked" and "guided". It is illegal for teachers to only carry out simple and rude corporal punishment and disguised corporal punishment in the education of students who violate discipline; From time to time, "containment" was carried out everywhere, and the result was that it was difficult to block and lost something; The best way is to "guide", take students as the center, follow the law of students' physical and mental development, respect students' individual differences, find the root of the problem, suit the remedy to the case and teach students in accordance with their aptitude, so as to better achieve the purpose of teaching and educating people. When teachers criticize and educate students, they should have a healthy psychology, use appropriate methods, integrate feelings and sublimate love, so as to get twice the result with half the effort and get rid of the disease with medicine. So, what should teachers pay attention to when criticizing students? First of all, teachers should always keep calm and think about ways to solve problems. Primary school is a critical period for students' physical and mental development, but students' psychology is still unstable, their self-control ability is poor, and their bad behaviors are repeatedly prohibited, which are manifested in the coexistence of childishness and maturity, independence and dependence, and conscious and random substitution. It is not in line with the objective reality and laws to expect discipline education to be done once and for all, and to expect all students to be disciplined and excellent. Our teachers should have a correct understanding and be psychologically prepared to deal with students' various problems. Second, teachers should pay attention to the language of criticism, so as not to hurt students' personality and self-esteem. Teachers and students are equal in personality. Although students who violate discipline sometimes have no view of right and wrong, they have strong self-esteem. The so-called "a scholar can be killed but not humiliated" is the truth. Therefore, teachers should pay attention not to be blunt and tactful, and not to hurt students' personality and self-esteem. At the same time, criticism should be practical and realistic, split into two parts, put more facts, reason and method. Only by making students feel the equality, care and love of teachers can he accept criticism from the bottom of his heart and correct his shortcomings and mistakes. Third, teachers should also be good at grasping the opportunity of criticism, take advantage of the situation and give guidance. When an underachiever encounters difficulties, misfortunes and diseases, the teacher leads his classmates to help him and says, "Today, teachers and classmates care about you so much and help you. You must fight for breath in the future! " Perhaps this sentence may become a powerful driving force for him to correct his mistakes in the future. Criticizing and educating students who violate discipline is a basic skill of teachers, and being good at critical education is an educational art. When criticizing and educating students who violate discipline, teachers should not only have the above-mentioned healthy psychology, but also have appropriate methods, and good methods can achieve good results. Improper criticism will hurt students' self-esteem and arouse their disgust; Appropriate criticism is like spring breeze and rain, which moistens things silently and benefits students a lot.
