Since the implementation of the new curriculum for many years, through study, training and practice, the new curriculum concept has been implemented by most teachers, but why do some students and teachers still like "free activities" and "teaching sheep"? Come to think of it, it is influenced by many factors. From the students' point of view, some students don't like physical exercise and are afraid of fatigue and heat. They think that physical education class is a "lesson of suffering" and they don't know enough about the importance of physical education class and the value of physical exercise. They think that physical exercise is not important as long as they are not sick. I either want to be free in class or ask for leave, which makes the teacher very passive. On the other hand, students don't like the teaching organized by teachers, think that the content is not suitable for them, or think that the teacher's teaching and exercise load is too heavy for the body to bear, resulting in rebellious psychology. And "free activities" just cater to students' psychology. They don't exercise or train, but they can do whatever they want and be real "free men". From the analysis of teachers, it can be seen that: ① If a teacher wants to have a good class, he must prepare teaching plans, students and equipment, which consumes a lot of energy and is troublesome, while the teaching of "herding sheep" does not need the above process and can also "cut corners". As a result, physical education teachers have a special liking for "herding sheep", and teachers' laziness psychology is also formed. ② The physical education teachers are weak. Some schools only have 1 ~ 2 official PE teachers, so many classes can't be taken over, so they have to ask non-professional teachers from other disciplines to substitute for them temporarily, and the interlacing is like a mountain. The organization of all kinds of teaching methods, the adjustment of formation and the demonstration of movements can't reach the standard, which leads to "herding sheep". (3) Teachers lack understanding of students' personality, teaching methods and modes are backward, and traditional teaching is continued, which makes students dislike it, leading to students wanting to act according to their own intentions. (4) The leaders have not paid enough attention to it. Because many of them are temporary substitute teachers, the leaders do not objectively evaluate the quality of physical education class, nor do they pay attention to the retraining of these teachers. They think it is enough to "keep classmates from making trouble", but they don't pay attention to it ideologically. This teaching method will change students' thinking, lead to lax discipline and absenteeism for no reason, and have a certain influence on the formation of students' outlook on life in the future. Their bodies are not fully exercised, their learning methods are not effectively mastered, and their lifelong sports concept is not cultivated. Safety accidents may also occur in the teaching of "herding sheep". Due to insufficient understanding of physical education class, loose classroom management and weak safety awareness, many shocking casualties have occurred. Many realistic examples tell us that "herding sheep" is really unacceptable. One of physical education class's learning goals is emotional goal, which requires cultivating students' good psychological quality, hard-working spirit and noble ideology and morality. To achieve these goals, can "teaching sheep" be realized? Can students get all-round development? Teaching and educating people is a teacher's bounden duty. Will these practices help to improve physical education teachers' organizational ability, control students' ability, and let students master 2-3 special skills? According to the newly revised curriculum standard, physical education and health course is a compulsory course with physical exercise as the main means, physical education and health knowledge and skills as the main learning content, and improving the health of primary and secondary school students as the main purpose. It is an important part of the school curriculum system and the only way to implement quality education and cultivate talents with all-round development in morality, intelligence and physique. If you don't do a certain amount of physical exercise, you want to strengthen your physique and cultivate your will quality, such as drawing water with a bamboo basket; Do not know anything about sports knowledge and skills, do not have a certain accumulation of sports knowledge and skills, and develop the habit of lifelong physical exercise, such as looking at the moon in the water. So how to effectively change this situation? First of all, physical education teachers should constantly learn the teaching concept of the new curriculum reform, prepare lessons conscientiously, arrange teaching methods reasonably, fully mobilize students' learning enthusiasm, teach students in accordance with their aptitude, and at the same time pay attention to promoting the professional level of physical education teachers. Secondly, standardizing classroom discipline, teachers recording students' usual attendance and classroom performance, and incorporating them into the results of the senior high school entrance examination can effectively mobilize students' learning enthusiasm. Thirdly, leaders should attach importance to physical education teaching, retrain professional or temporary physical education teachers regularly, check lesson plans and teaching regularly, use certain incentives to improve teachers' enthusiasm, make classroom management effective, optimize teaching methods, greatly improve efficiency, completely put an end to "free activities" and "herding sheep", and let students develop lifelong sports consciousness, so that they can completely abandon the idea of "liking physical education class but not physical education class" and return to the playground.
