Application of combination of case-based learning and problem-based learning teaching method based on information platform in hepatobiliary surgery teaching

Abstract

Objective To investigate the relying on the information platform (teaching website), on the foundation of classical case database, CBL (case based learning, CBL) combined with PBL (problem based learning) teaching method application in clinical hepatobiliary surgery teaching effect. Methods 24 clinical trainees were randomly divided into the experimental group (CBL+ PBL group, 12) and the control group ( traditional teaching group, 12). Experimental group in the teaching website established classic case database, teaching process by the CBL began, students on the web site of classical case database to autonomous learning, a comprehensive understanding of the case from the pathogenesis, clinical manifestations to the complaints, symptoms, signs, history collection, diagnosis, laboratory examination, therapy. Teachers set up the problem of classic cases to discuss the case study under the guidance of teachers. The control group of teachers in theory teaching, teaching rounds and observe the operation etc.. After the study of the two groups of theoretical knowledge and clinical operation to test. Students in the experimental group were surveyed by questionnaires to evaluate the teaching methods. Results The experimental group’s theory test score (92.1±0.95) points, better than the control group (87.5±0.62), the difference was statistically significant (t=7.984, P<0.05). The clinical skills of the experimental group were (90.9±0.95), which was better than the control group (86.3±0.88), the difference was statistically significant (t=8.027, P<0.05). The results of the questionnaire showed that more than 90.0% of the students thought that the teaching method could arouse the enthusiasm of study and improve the efficiency of study. Conclusions Relying on the information platform, CBL and PBL are organically combined, applied in hepatobiliary surgery teaching, stimulate the students’ interest and improve the teaching effect.
