Abstract:
Objective:To explore the influence of flipped classroom combined with case-based learning (CBL) teaching mode on teaching effect of X-ray cephalometric analysis in orthodontic experimental class.Methods:In the study, 70 undergraduates majoring in stomatology were selected as research objects and randomized into teaching reform group and traditional group in average. Flipped classroom combined with CBL teaching mode was adopted in teaching reform group, while traditional group adopted traditional teaching mode. Questionnaire was used to investigate the students' evaluation on the two teaching modes, and the accuracy of the measurement of X-ray cephalometrics of the two groups was compared and analyzed respectively. GraphPad Prism 7.03 software was used to perform t test and chi-square test. Results:Teaching reform group believed that this kind of teaching mode could improve the ability of self-study, communication coordination ability, independent problem solving ability, and logic and language expression ability, deepen the understanding of the project connotation, and apply the X-ray cephalometrics to the actual clinical case analysis and diagnosis. Compared with the traditional group, there were significant differences ( P<0.05). In the accuracy evaluation of measurement values, the absolute values of 70% measurement items in teaching reform group were higher than those in the traditional group, but the difference was not statistically significant ( P>0.05). Only in bone type Ⅲ malocclusion, the absolute values of Y-axis angle and FMA were lower than those of the traditional group, and the difference was statistically significant ( P<0.05). Conclusion:Flipped classroom combined with CBL teaching mode can help students improve self-study ability, communication cooperation ability and the ability of solving problem independently and clinical application. However, the accuracy evaluation of measurement values in teaching reform group were lower than that of the traditional group, indicating that this teaching method in the experimental teaching of X-ray cephalometric analysis needs to be further improved.
