There are generally two ways to study mathematics learning. One is to explain and analyze the specific problems of mathematics learning from the theory of general psychology; The other is to study the real psychological activities of students' learning from the concrete process of mathematics learning, analyze their cognitive process, mechanism and psychological changes, and gradually form a mathematics learning theory with its own characteristics. Although the International Research Organization of Mathematics Education Psychology (PME) under the International Committee on Mathematics Education (ICMI) strongly advocates the second method, from the actual situation of the current research, the above two methods are both necessary and often complement each other in specific applications, so it is difficult to distinguish them. Especially due to the great progress of modern educational psychology theory, we should pay more attention to using its rich theoretical framework and diversified academic perspectives to deeply understand the psychological laws of mathematics learning.
