Application of Digitally Assisted CBL Teaching Method in Postgraduate Education of Orthodontics
Objective To explore and analyze the teaching effectiveness of digitally assisted case-based learning(CBL)in postgraduate education of orthodontics.Methods A total of 40 postgraduate students from the 2022 and 2023 cohorts of the department of orthodontics at the Affiliated Stomatological Hospital of Nanchang University selected from July 2023 to January 2024 were randomly assigned into two groups:a conventional teaching group and a digitally assisted CBL teaching group.The quality of students'model analysis and cephalometric assignment reports was assessed,and a questionnaire was used to evaluate students'satisfaction with the digitally assisted CBL teaching method.Results In the model analysis,the digitally assisted CBL teaching group showed lower values for dental arch width,curvature of spee curve and the Bolton Index.In cephalometric measurements,the differences in the SNA(sella-nasion-A point angle),ANB(A point-nasion-B point angle),MP-SN(mandibular plane to sella-nasion angle),FMA(frankfort mandibular plane angle),and IMPA(lower incisor mandibular plane angle)were(0.43±0.20)mm,(1.22±0.51)mm,(1.26±0.83)%,(2.12±1.17)°,(1.71±0.65)°,(1.12±0.73)°,(0.87±0.49)°and(2.76±1.49)°,respectively,all of which were lower than those of the conventional teaching group[(0.92±0.43)mm,(2.34±1.82)mm,(3.07±2.38)%,(4.38±1.89)°,(4.66±1.58)°,(4.19±2.05)°,(3.77±1.94)°and(4.98±2.37)°],and the differences were statistically significant(P<0.05).The results from the satisfaction survey showed that the digitally assisted CBL teaching method was superior in five aspects:time-saving and efficient operation,high accuracy and repeatability,increased classroom engagement and learning enthusiasm,improved understanding of clinical theoretical knowledge,and enhanced ability to diagnose and treat common clinical conditions.Students also expressed a preference for more digitally assisted CBL courses in the future.Conclusion Digitally assisted CBL teaching method is effective in improving the teaching outcomes of practical education for postgraduate students of orthodontics and serves as a supplement to traditional orthodontics teaching methods.
