Abstract
To establish the PBL designed experiment teaching model and to evaluate its teaching effectiveness.we use the questionnaires and the experiment skill test and the experiment content related written examination and the theoretic examination to evaluate its teaching effectiveness. The PBL group is significantly higher in the comprehension and the synthesizing ability and so on than the control group (P<0.05). The PBL group has significantly higher mean scores in the experiment content related written examination than the control group (P< 0.01). The PBL group has significantly higher scores in the theoretic examination than the control group (P< 0.01). The PBL designed experiment teaching can better train students for the innovative thinking ability and the scientific research capabilities. Key words: Problem-based learning; Designed experiment; Teaching model; Medical microbiology
