1. Defining purpose and function Dialectical materialism tells us that thought (purpose) is the guide of action, and what kind of action will be taken if there is any guiding ideology. So I stimulate students' interest in learning by letting them look at the physical form first. For example, I teach the first physical labor class in autumn in the third grade of primary school? Container truck? At that time, I showed my container truck and introduced the new lesson before class. When the students saw the van, they immediately came to the interested teacher. This boxcar is really beautiful. It must be very interesting. How is this done? ""teacher, we also want to learn, please teach us quickly! " The students scrambled to ask questions, showing a strong thirst for knowledge. Therefore, I seized the opportunity to let the students know the purpose and function of hands-on operation, and let them know that having strong hands-on operation ability can make our work and study even more powerful. On the contrary, poor hands-on ability will bring a lot of inconvenience to work, study and life, and even inconvenience to move. It can be seen that if you want to become a cross-century architectural talent and a qualified "five small" citizen, you can't do it without strong hands-on ability. Second, the combination of imparting knowledge and cultivating students' ability is based on mastering knowledge. Therefore, after teaching students to "nail buttons", I asked them to straighten out the order of nailing buttons one by one according to the requirements of the text, and let them tell each step of nailing buttons. Then, I asked the students to take out thread balls, needles, scissors and unbuttoned clothes and learn to sew buttons by themselves. The students feel very novel and enthusiastic. Although they were in a hurry, nailed slowly, sweaty, and some even accidentally stabbed their fingers, they still refused to give up. Many things happen. Finally, they saw the buttons they had nailed. Although they are not strong enough, they are still dancing happily, totally immersed in the joy of success. After all, a good beginning is half the battle. Finally, we let them compete in groups to see who can nail well and quickly, and finally give the winner full recognition. It can be seen that in the labor class, combining the imparting of knowledge with the cultivation of students' practical ability is not only conducive to the improvement of primary school students' practical ability, but also cultivates students' innovative ability. Third, moral education should be incorporated into labor teaching. As the new San Zi Jing said, "the method of teaching is the first", so the importance of moral education can be seen. Moral education is not only carried out from the subject of moral education, or the class teacher carries out simple ideological education. Our labor discipline also shoulders the task of education, so we should attach importance to moral education in labor teaching. In labor teaching, I combine the content of teaching materials to carry out ideological and political education for students, and on the basis of making full use of the moral education factors of teaching materials, appropriately broaden and deepen them. For example, when I was teaching homemade mopping, my classmates quickly learned homemade mopping, and all of them were beaming. Some fast-moving students made several mops, so I asked, "Can you use all these mops at once?" The students said in unison that they could not use it up. As soon as I saw the opportunity, I asked: Who do you care about in the' Five Hearts' education? "Others" students answered in unison, so I asked, "So who needs our care most? "Several' lonely old people' students immediately said that once reminded, other students also suggested mopping the floor in the nursing home with the third class, which not only educated the students on morality, but also allowed them to test the quality of mopping the floor. More importantly, it has cultivated their practical ability and laid a solid foundation for being a qualified "five small" citizen.
