Exploration of Problem-Based Learning Using 3D Printing Molds to Cultivate Critical Thinking Skills in Resident Physicians
Objective:To investigate the impact of problem-based learning using 3D printing molds(PBL-3DM)on the critical thinking(CT)ability of resident physicians.Methods:Thirty-seven specialty resident physicians from our hospital were selected for PBL-3DM teaching,and changes in CT were surveyed before and after teaching.Results:Before teaching,the mean CTDI-CV value of the subjects was(228.38±5.30),with 83.8％of subjects not reaching positive CT and 24.3％lacking CT,and all 7 dimensions of ability were suboptimal.The CTDI-CV values at 2,4,and 12 weeks after teaching gradually increased to 245.40±5.32,278.29±6.28,and 326.46±3.37,respectively,with the proportion of negative CT decreasing to 27.0％and the proportion of no CT decreasing to 0％(P＜0.05);at 12 weeks,all dimensions except analytical ability and cognitive maturity showed significant improvement(P＜0.05).Graduate resident physicians had the highest proportion of negative CT(35.1％),while standardized resident physicians had the lowest proportion(21.6％),with the most significant improvement observed in graduate resident physicians and the least improvement observed in visiting resident physicians.Conclusion:PBL-3DM teaching method helps to improve the critical thinking ability of resident physicians with different backgrounds.
