In the process of promoting quality education in an all-round way, physical education, as an indispensable part of school quality education, shoulders the main task of improving children's physical quality, and ideological and moral education is also one of the educational goals of physical education. Therefore, physical education teachers should educate students consciously, purposefully and systematically in their daily physical education work, which requires physical education teachers to understand the personality and psychological characteristics of contemporary junior middle school students, realize that moral education is an important part of physical education teaching objectives, and creatively infiltrate moral education into physical education class. First, the personality and psychological characteristics of junior high school students, because of their semi-maturity and semi-naivety, are often in a contradictory state, manifested in rapid physical development and sexual maturity, with strong pursuit and feelings for maturity. Their attitudes towards people, things, emotions and emotional expressions, as well as the content and direction of their behavior have changed obviously, and they are also eager for the trust and respect of society, schools and parents. On the other hand, due to their cognitive ability, thinking mode, personality characteristics and naivety of social experience, although abstract logical thinking is the main form, their level is still relatively low, and they are in a transitional period from experience to theory; Therefore, in terms of personality characteristics, there is still a lack of deep and stable emotional experience of adults and a lack of willpower to bear pressure and overcome difficulties; Social experience is also lacking. Second, the importance of physical education class's infiltration of moral education physical education class is a course with students' direct participation in practical activities as the main body. Based on the above-mentioned understanding of junior high school students' psychological characteristics, students' ideological consciousness, advantages and disadvantages are often revealed in their words and deeds when they are actively exercising in physical education class. Therefore, teachers can make use of every part and link of physical education class to carry out ideological education for students, fully stimulate students' subjective initiative, and enable physical education class to achieve the purpose of entertaining education and moral education throughout the whole process. Of course, in order for students to form a good code of conduct, moral education must have a process from quantitative change to qualitative change. Therefore, only by unremitting efforts can we achieve fruitful and ideal results. Third, several methods of moral education in physical education class 1. A purposeful method. Teachers can briefly explain the significance of this class according to the teaching content, so that students can be prepared to study hard and pave the way for the smooth implementation of teaching. For example, in the teaching of queues and formations, teachers should first explain the importance of collectivism and let them understand the importance of unity and cooperation. Then, they should pay attention to observe every student, criticize and educate students who do not perform well in queue and formation, educate them to be diligent in practice, observe discipline, and cultivate strict organizational discipline and collectivism spirit. 2. Timely praise method. In physical education teaching, teachers should fully affirm students' good thoughts and behaviors in time. For students who have accomplished their tasks well in practice, teachers can arrange them to practice some ball games they like, which is an invisible spur to other students. Students with poor grades in the past should actively create environments and opportunities to give them a chance to shine, praise them realistically and treat them equally. 3. Infection edification method. In the process of physical education teaching, students' physical activities present various postures, and so do their ideological activities. The ideological activities in sports activities are often fleeting and tiny, which need teachers' careful observation, timely discovery, active guidance and close attention to education. Let good thoughts and behaviors infect and edify other students, thus forming a good atmosphere in physical education teaching and educating all students. 4. Activity education law. In the process of physical education, students have to bear great muscle fatigue. Teachers should consciously make students realize that the exercises they endure will be rewarded accordingly, so that they can work harder and be more serious in practice. For example, if you do sit-ups 1 min, you should first tell the students that when you do it for 35 times, your muscles will feel sore, so you must keep doing it, otherwise your grades will never stop but you will not improve, so let them keep doing it. For another example, in the teaching of middle and long distance running, teachers should first explain the physiological phenomenon of "pole" to students, encourage them to overcome this phenomenon with tenacious perseverance and will in practice, and gradually cultivate their excellent qualities of hard work, courage and tenacity. 5. Competitive introduction method. With the development of society, the competitive mechanism of survival of the fittest has emerged in all walks of life. Physical education teachers can also consciously cultivate students' sense of competition according to the characteristics of different projects in the teaching process, so that they can taste the joy of victory, the pain of failure, the joy of progress and the joy of struggle in the competition. For example, in relay teaching, students can be divided into several groups, and the last group of students who reach the finish line are required to do push-ups, so that students can realize that victory and failure will bring two different results. Teachers can seize the opportunity to cultivate their sense of competition and encourage them to beat their opponents in the next competition. For example, ball games can also be divided into several groups and played in turn. The defeated team is not qualified to participate in the competition, and other teams continue to compete, so that they can try their best to beat their opponents in the competition and ensure that their team can continue to compete, thus cultivating students' tenacious sense of competition. 6. Problem discussion method. For example, in martial arts teaching, students can be asked some questions in movies or novels by asking questions, such as "What is the priority of martial arts", and then students can answer them, so that students can have a further understanding of "morality is the priority of martial arts", thus cultivating students' good psychological quality and noble moral sentiment of respecting teachers and attaching importance to teaching, being polite and trustworthy, and being tolerant of others. 7. Example incentive method. The power of example is infinite. In middle school physical education class, teachers can make full use of heroic model figures and good teachers' morality to cultivate students' emotions, thus stimulating students' enterprising spirit, cultivating strong will, and developing good quality and good behavior habits. 8.
