Objective To evaluate the effects of pharmacology problem-based learning（PBL） teaching. Methods According to scores of entrance exam, the freshmen in grade 2007 and 2009 of Hubei University of Medicine were divided into experiment and control class by stratified random. Their pharmacology exam scores were analyzed in aspect of average score, excellence percentage, pass percentage and subject category in 2009 and 2011. The satisfactory degree of students in grade 2009 for teaching effects was investigated with questionnaire at the end of pharmacology teaching in2011. Group comparisons on average score and percentage were carried out with u test and chi square test, respectively. Results The average score, excellence percentage and pass percentage of PBL experiment classes of grade 2007 and2009 were better those of control classes（P 0.01 or P 0.05）. With regard to the scores of distinguished type subjects, PBL experiment classes also surpassed control classes or had the trend of surpassing the latter, except for understanding contents. The questionnaire investigation showed that the satisfactory degree of experiment class in grade 2009were better than control class in the aspect of ten indices of teaching effect obviously（P 0.01 or P 0.05）. Conclusion The effects of PBL teaching are excellent and students have high satisfactory degree to it. It has benefit for cultivating high-quality talents.
