For students, interest and curiosity are the prerequisites of autonomous learning.Students ’autonomous inquiry often stems from the problem, and the enrichment of the knowledge system and the solution of the problem will also bring the students’ satisfaction.For the teacher, creating the problem situation , To be enlightening, easy to moderate, small and fine, not deviate from the textbooks, nor from the student’s actual life, to help students understand the concepts and develop students’ mathematical ability. Teachers should be good at creating suspense, the problem as the introduction of the incision , To encourage students to learn.
