Have a direct relationship. In the early stage of teaching, you will encounter many problems you don't know. Children in every grade have different problems. At first, it may only be aimed at students of one grade. Once you transfer to another grade, you will find it a new challenge. The more grades you teach, the more you teach, the smoother you will teach, just as the new teacher's class time and the design of teaching content are not very certain, while the old teacher can end a class more easily and casually. To accumulate experience, first of all, you should try more, and also learn from the experience of old teachers, record the problems you encounter, and after solving them, it will become your experience ~ After a period of time, your teaching experience will be directly proportional to your experience ~
