While promoting quality education in an all-round way, it is our goal to guide students to develop their own personalities and specialties. Psychologists believe that "all effective activities must be based on a certain interest." Specialty is an ability that obviously exceeds the average level of peers. To realize everyone's specialty, we should take hobbies as the basic point of training. (1) Try to collect the personal information of the whole class, establish a study file for each student, and fully understand each student's personality and hobbies. (2) Enrich the professional selection projects. Offering musical instruments, painting, sports, chess, computers, ball games, calligraphy and many other specialties that meet the age characteristics of primary school students. It provides a broad space for major selection. (3) Let students know the characteristics and requirements of each major, and ensure that students can choose the learning content that they are most interested in and most in line with their own reality. Profession is not formed overnight. In the process of learning and training, if you lose confidence and change your mind when you encounter difficulties, then the major can only be unattainable for students. Pragmatic, tough and other will qualities are the basis for the continuous progress of special students. Therefore, it is necessary to carry out targeted scientific training for students in a planned way, effectively cultivate and enhance students' interest and improve their special skills. According to students' hobbies and specialties, it is an effective way to cultivate primary school students' specialties by breaking class boundaries, classifying classes, arranging special training for students by teachers with expertise in a planned way, arranging certain time every week, regularly tutoring teachers and students, following scientific principles and persistently carrying out planned and strict specialty training. However, it is a complex and arduous project to cultivate the special skills of primary school students, and it is difficult to complete it smoothly only by setting up special skills training activities in schools. This requires the joint efforts of schools, society and families to integrate various forces in order to achieve good results.
