In this regard, as a primary school class teacher, I think it is very necessary to do a good job in safety education for primary school students scientifically. First of all, it is necessary to clarify the responsibility of the class teacher and strengthen the safety awareness of primary school students. In recent years, the number of primary school students has greatly increased, the phenomenon of campus socialization has become increasingly obvious, and the environment in and around the campus has become increasingly complex. Therefore, it is urgent to implement various safety education measures and improve the safety awareness of primary school students. The head teacher shoulders the responsibility of safety notification, warning, prevention and rescue, and should give students safety education and self-care and self-help education, so that students can master the basic knowledge of safety prevention and self-care and self-help. Such as traffic safety, fire safety, personal safety, property safety, food hygiene and safety education for students. In particular, students' dangerous behaviors or potential dangerous behaviors should be warned, stopped and corrected in time. We should guard against all kinds of activities in the class, contradictions and disputes between students, bullying on campus, including hidden injuries, rather than just mending it after it is too late. In the event of a safety accident, students should not only report it in time according to the regulations, but also do their best to protect themselves and take effective measures to prevent the accident from expanding. Secondly, it is necessary to scientifically educate primary school students and promote the formation of safety norms. Nowadays, primary school students are lively and eager to learn, but they are rebellious. To manage class safety scientifically, the head teacher must assess the situation, respect students' personality differences, and correctly treat and deal with bad behaviors of different natures. Criticism of students should pay attention to art, encourage more and blame less; The requirements for students should be balanced by Yan Kuan, strict and moderate, wide and limited; We should communicate with students in a democratic and equal way, communicate more and reprimand less, be students' intimate friends and be students' loving elders. Only by gaining students' trust and respect for themselves, can we find out the hidden dangers in the class in time and rely on students to eliminate them in time and accurately. Third, we should build a student autonomy model and innovate the management mechanism. In view of the independent characteristics of primary school students, class teachers can give full play to students' collective strength, build a student safety autonomous management model, set up student autonomous organizations such as safety hidden danger investigation team, contradiction and dispute monitoring team, code of conduct supervision team, emergency accident handling and report team in class, improve the class safety management system, and grasp the class situation, grasp the trends and strategize through these organizations to find and eliminate safety hidden dangers in time. Fourth, we should strengthen the tripartite linkage and implement safety management. Class safety management can't rely on the head teacher alone. Only by strengthening the contact with classroom teachers, school organization departments and students' parents can safety management be implemented. The head teacher can ask the teacher to observe the students' words and deeds and emotions in teaching, so as to grasp the students' psychological changes at the first time. The school is required to organize and carry out ideological and moral, safety laws and regulations, safety knowledge education, and safety hidden dangers investigation and rectification activities. The head teacher should strengthen communication and exchange with parents, publicize the systems, methods and administrative regulations on school safety management to every parent, and strive for the understanding, support and cooperation of parents to the maximum extent. Finally, safety precautions should be taken to ensure the safety of the campus. The head teacher should give a good safety education class seriously and organize safety knowledge tests regularly. Carry out campus safety work in many aspects and activities, such as full-time safety education, safety drills for teachers and students, and warning experience outside the school gate, and formulate detailed implementation plans and activity safety plans, carefully plan and carefully arrange them, so that the wind of safety and harmony can blow all over the campus. School safety is no small matter, and class safety is the key. Only when students and teachers have a sense that safety responsibility is more important than Mount Tai, especially the head teachers should make clear their own safety management responsibilities, correctly implement class safety management methods, innovate safety management models, and build a trinity safety management network of school, family and society, can the safety of primary school students be truly ensured.
