In the past years we have got great achievement in education. But it haven' t make a breakthrough. The reason is that we have overlook the reforming of the models of teaching. Models of teaching is monotonous. As result, the students' new role and their question consciousness have lost.

The writer believed it an objective to put into effect the new models of teaching in biology teaching . In this article, an new model of teaching—Problem-Based Learning(PBL) was introduced. The new teaching model can change the education condition and adapt the tendency of education in the world.In the second part, The Problem-Based Learning was expounded. Problem-Based Learning(PBL) is an models of teaching which embodies the opinions of constructivists. It comes into being in mid-20^th century at the request of the reform in medical education. Despite various interpretations of this concept, PBL is virtually characterized by problem-centered learning in group and students' self-determination. The comprehension of "problem" will reach a better understanding of pedagogical ideology of this method. There have been controversies over the effects of PBL on the quality of knowledge acquisition, but it is admitted that this method can enhance learning motivation, higher order thinking, the ability to gain and apply knowledge, and skills of social interaction. The whole PBL flow subsumes five phases: (1)designing of problems (2)presenting/encountering problems. (3)self-directed learning (4)attempting to solve problems with new knowledge (5)summarizing ,reflecting, and evaluating learning processes.
