As a bilateral activity, teaching is inefficient and even ineffective without the effective participation of students. Constructivism theory of learning that learning is not the process of teacher to pass the knowledge of students, but students themselves take the initiative to construct knowledge process. This construction can not be replaced by others, but rather the students themselves through direct participation in a variety of experimental learning activities. However, under the influence of long-term exam-oriented education in the third year of chemistry teaching review, given the characteristics of chemical knowledge, complexity and miscellaneous, teachers tend to help students build a knowledge system by inducing, summarizing and listing knowledge points,
