Both emphasize that the teacher The starting point is to regard students as the main body of education, while the latter also sticks to its leading role as a teacher and constructs a new teaching mode based on the strategy of “teaching-learning” and bilateral promotion so as to improve the effectiveness of primary mathematics classrooms.
