Application of CBL in the teaching of knee MRI for orthopedic residents / 中华医学教育探索杂志

ABSTRACT

Objective:To study the effect of CBL on the teaching of knee magnetic resonance image (MRI) for orthopedic residents.Methods:From September 2015 to March 2018, CBL teaching method was applied in the teaching of knee MRI among 90 orthopedic residents of Arthritis Clinical & Research Center of Peking University People’s Hospital. The teaching effect of CBL was evaluated with questionnaire method. The scores of Knee MRI theoretical knowledge and image diagnosis were statistically compared after CBL teaching. SPSS 19.0 was performed for t test. Results:According to the questionnaire of 90 orthopedic residents, in the teaching of knee MRI, CBL teaching improved the residents' learning interest[77.8%(70/90)], fortified their theoretical knowledge[80.0%(72/90)], and enhanced their diagnosis ability of knee MRI[88.8%(80/90)], diagnosis ability of knee diseases[86.6%(78/90)], autonomous learning ability[84.5%(76/90)], expression ability[83.3%(75/90)], and the ability of creating active classroom atmosphere[51.1%(46/90)]. The performances of knee MRI theoretical knowledge and image analysis were significantly increased after CBL teaching, respectively from (65.35±10.36) points to (89.20±10.55) points and from (66.64±9.88) points to (89.50±10.06) points.Conclusion:CBL teaching can improve independent diagnostic ablity of knee MRI of orthopedic residents and lay a solid foundation of diagnosis and treatment for knee diseases, thus improving their clinical skills.
