Quasi - experimental method with nonequivalent pretest-posttest controls is adopted. The subjects in this study are from two classes with a total of 66 students.Quantitative analysis and qualitative analysis are emphasized in this study.Some main findings are showed as follows: 1.Informal knowledge According to the result of the pretest and interview, it shows that there are some misconcepts in angle length area constructing graphs scale and ratio sense in the situations of enlargement and shrink.They often come from intuition the meaning of words and teaching. 2.The effect of learning for students There are two significant learning effects for treatment group and control group:immediate effect (posttest vs. pretest) and reserved effect(follow-up test vs. pretest),but no significant retained effects (follow-up test vs. posttest) for both groups. After excluding pretest, there is a significant difference in posttest for the girls and the low achievement students in treatment group and in control group. 3.The performance of conceptual change Generally, the treatme
