Abstract：In the new objectives of education reform, high school physics classroom teaching time compression, the traditional teaching model of the physical classroom can not be successfully completed task. Teaching of physical exercises motif appears, for students and teachers learning and teaching of the new shortcut. Based on the optical parts of high school physics teaching materials, teaching counseling summary of data analysis, the use of physical laws of association, described the choice of motif and design principles put forward motif selection and design of teaching methods and the advantages of Motif, the Motif The selection and design to provide theoretical guidance.
