2. Presentation of resultsThis middle school has integrated the course of self-defense in physical education class from Grade One to Grade Three. They made a systematic teaching plan, and the first stage mainly focused on the teaching of theoretical knowledge and basic movements. For example, in the theoretical course, the weak parts of the human body, such as eyes, throat and knees, will be explained in detail, so that students can understand the effectiveness of attacking these parts in self-defense. At the same time, the basic movements include simple self-defense postures, such as standing sideways and protecting the head with both hands.After three years of teaching, the students' awareness and ability of self-protection in the face of dangerous situations have been significantly improved. According to the school's statistics, in a questionnaire survey on campus safety awareness, more than 80% of students said that their ability to identify and cope with dangers has been greatly improved. Moreover, in the self-defense skills assessment organized by the school, most students can master the skills they have learned and make correct responses in simulated dangerous scenes.

In the third grade, the practicability of self-defense is further strengthened, and some methods to deal with dangerous weapons such as knives and sticks are taught. By training with simulated weapons, students can master the skills of dealing with dangerous weapons while ensuring safety.In the evaluation of safety education in this school, it is found that students have a high degree of acceptance of self-defense techniques. After a period of teaching, students performed well in the simulation test in the face of dangerous scenes. At the same time, the school also found that due to the self-defense course, students' slapstick behavior in recess activities has also decreased, because they know better how to avoid hurting others and protect themselves.

In the second stage of junior high school, some simple practical drills and escape skills began to be added. For example, design a simulation scene, so that students can practice how to break away from each other's control and escape quickly in the simulated school bullying scene. Teachers will give targeted guidance according to students' performance, emphasizing the importance of speed and agility.In the senior grades (grades 4 to 6), the teaching is conducted by means of scenario simulation. For example, simulating a scene where a stranger pulls on the road, the teacher will guide students how to deal with the danger by shouting for help and using schoolbags and other items for self-defense. This interesting and practical teaching method allows students to learn self-defense in a relaxed and pleasant atmosphere.Summary: The successful cases of self-defense and self-defense in physical education class in these schools show a variety of feasible ways, whether it is a systematic teaching system, a diversified curriculum model or an interesting and practical teaching method, which has achieved good results. These successful experiences can be used for reference by other schools, so that more students can learn self-defense through physical education class and enhance their self-protection ability.
