According to the new teaching concept, Jiayin has established the teaching concept of "direct communication" since its establishment. Teachers should put down the shelf of "teaching dignity" and try to awaken students' subjective consciousness. In the classroom, teachers should change from the master and operator of teaching to the guide and motivator, encourage students to speak boldly, ask questions and express their personal views, and create an all-English teaching environment. At the same time, it is necessary to change the past educational concept of emphasizing uniformity, strive to explore hierarchical teaching under the existing conditions, and design different teaching objectives according to the differences of students.
