Thinking on the Teaching Implementation of "Synthesis and Practice" in Junior Middle School Mathematics Based on Situational Cognition Theory

"Synthesis and practice" is one of the important teaching contents in mathematics curriculum since the new curriculum reform. Through "synthesis and practice" is helpful to improve students' core quality of mathematics. Situational cognitive theory is a learning theory with extensive influence formed in the middle and late 1980s. Through consulting the existing literature, it further expounds the situation on the basis of understanding the situational cognitive theory, and the enlightenment of cognitive theory to the teaching implementation of "synthesis and practice" in junior middle school mathematics. For example, creating real life situation, restoring the essence of mathematics; establishing mathematics learning community cooperative learning; project integrating multiple situation teaching.
