The curriculum reform emphasizes changing students’ learning styles as a breakthrough and reshaping students’ main position in learning activities. The 2011 edition of the junior high school math curriculum standard (hereinafter referred to as the new curriculum standard) clearly states that “implementing heuristic teaching can help students The main body position and the teacher’s leading role. The teacher’s enlightening lectures; Creation of situational, design problems, guide students to explore independently, cooperate and communicate; Organize students to operate experiments, observe phenomena, make conjectures, and infer theoretical evidence, etc. Inspire students thinking, make students become the main body of learning, and gradually learn to learn. “effective mathematics teaching activities should reflect ”people-oriented " concept,
