In teaching activities, teachers play a dual role, on the one hand to play the role of “teaching ”, as a student mentor and leader, on the other hand to be able to age characteristics of students, the status of knowledge and life as a prerequisite , Examine the content to be learned from the student’s perspective, play the role of “learning”, and work with students to become explorers of new knowledge and skills ~ ([1]).
