Application of three-dimensional animation educational software combined with CBL in in-guinal hernia teaching / 中华医学教育探索杂志

ABSTRACT

Objective To explore the application and effect of three-dimensional animation teaching software combined with case based learning ( CBL ) in inguinal hernia clinical teaching . Methods Totally 30 eight-year program students of Grade 2008 of Peking University People's Hos-pital were randomly divided into the teaching software combined with the CBL group(n=15) and tradi-tional teaching group(n=15). Three-dimensional animation teaching software was used to simulate the whole process of inguinal hernia anatomy and physiology, pathogenesis, clinical manifestations, diag-nosis and treatment in teaching software combined with CBL group. CBL teaching was conducted by setting problems through typical case and case discussion under the guidance of the teacher . The teacher-centered teaching, teaching rounds and watching operation were used in the traditional teaching group . Theory examination and physical examination were given at the end of the study and achieve-ment differences were compared between 2 groups. Questionnaire was used to investigate students' evaluation of the teaching method in teaching software combined with the CBL group and data were statistically described using t test. Results Theoretical exam score of the teaching software combined with the CBL group was (94.80±1.54), superior to the traditional teaching group(86.10±1.86), and the difference was statistically significant(t=8.242, P=0.000). Clinical skill test score of the teaching software combined with the CBL group was (91.10±1.01), superior to the traditional teaching group (85.90±2.17), and the difference was statistically significant(t=8.531, P=0.000). The survey result showed that more than 80.00% students thought that this teaching method could arouse students' learning enthusiasm, promote their mastery and application of knowledge, strengthen their self-study ability, cultivating their clinical thinking and improving their learning efficiency. Conclusion The teaching method of three dimensional animation teaching software combined with CBL , as a new teaching mode, helps to improve the quality of teaching.
