Medicine is a discipline for the health and life of the people. Medical students bear the future of medical career, so cultivation of medical students is of important significance. In the process of learning medical knowledge, understanding and memory are both very important. And only on the basis of understanding can we better memorize and use the medical knowledge learned. The traditional teaching is mainly based on "imparting style" , the teachers are the disseminators of knowledge, while students do not have the awareness and opportunity to participate, so that the level of teaching directly affects the teaching effect. Therefore, we should actively use a variety of teaching methods to give full play to students′ enthusiasm, initiative, and creativity, in order that medical students can master multi-disciplinary medical knowledge, and be able to apply it flexibly in clinical practice, so as to promote the development of medical science.
