Abstract: Objective: To analyze the effect of problem based learning(PBL) teaching method on Evidence based medicine of medical students, and to provide a scientific basis for improvement of teaching methods and effect. Methods: 696 five-year and eight-year medical students from 2008, 2009 and 2010 grade were selected as study objects by random sampling. Each student was asked to fill in the questionnaire after the course. The mean score of each first and second class indices were calculated, and the difference of each indices in each grade and each specialty were tested using F test and t test. Results: The mean score of the four first class indices were 3.6,3.2, 3.7 and 3.8. The mean score of each indices in 2010 grade were the highest in the three grades, with the significant difference of the score of Q2 and Q3 in these three grades(Q2: F=3.28; Q3: F=4.25; P<0.05). The mean score of each indices in eight-year students were higher than that of five-year students, with the significant difference of the score of Q2 and Q3 in these two types of students(Q2: t=2.33;Q3: t=2.08; P<0.05). Conclusion: The PBL teaching method is in good effect and its effect is improved with time. The effect of PBL teaching in eight-year students is better than that of five-year student.
