Happy sports advocates giving full play to students' initiative and creativity in learning, leaving room for students to think and create independently. Students' learning includes three stages: the initial experience of sports (trying)-challenging new learning goals (learning)-carrying out creative learning (innovation). In this survey, 23% of the students in physical education class are motivated by entertainment and fun. They are in high spirits and concentrate on the textbooks they are interested in. Confucius said, "Knowing is not as good as being kind, and being kind is not as good as being happy.". Without happiness, how to improve students' physical quality in an all-round way? They don't want to run every day and dribble and play basketball in every class. They need novel, practical and challenging textbooks. Therefore, only by actively and constantly updating teaching methods, constantly innovating teaching, correctly guiding students' learning motivation and fully mobilizing students' practical enthusiasm can teachers improve learning efficiency and teaching effect.
