Yes what you are saying is right that teacher's role is to impart their knowledge to their students. Teachers are the source of learning for students. Students are taught to read, write and count from the teacher. Besides, students get new knowledge and character education from the teacher. After the biological parents stay at home, the teacher is the second parent who lives in the school. But before these lessons, the teacher's teaching environment must be created. Education does not happen in all environments. Thank you very much for your nice comment but maybe I didn't understand you the way I understood you. Thank you very much @amryksr
