Application of sandwich teaching method based on CBL principle in clinical teaching of pediatric surgery combined with network database

Abstract

Objective To investigate the application of sandwich teaching method based on CBL principle in clinical teaching of pediatric surgery combined with network database. Methods A total of 147 undergraduate students in clinical medicine were selected and randomly divided into experimental group (84 persons) and control group (63 persons). The experiment group used sandwich teaching based on CBL principle + bedside demonstration + network resource library, while the control group adopted traditional teaching + bedside teaching. The teaching effect was evaluated through theoretical and practical examinations and quantitative feedback questionnaires. The t-test of independent samples was performed in two groups, and the scores of the questionnaires were matched by paired t-test. Results The scores of network test, case discussion, summary and written test in the experimental group were better than those in the control group [(37.56±1.32) vs. (35.10±1.25); (27.61±0.94) vs. (24.71±1.51); (27.02±1.11) vs. (26.29±1.30); (88.28±1.97) vs. (83.60±4.58)], the difference was statistically significant. The questionnaire survey showed that the students in the experimental group were better than the control group in the learning efficiency, team cooperation, independent thinking, theory connection, and so on. Conclusions The sandwich teaching method based on CBL principle, combined with the network database, is better than the traditional method in the clinical teaching of pediatric surgery, and can promote the theoretical and overall teaching effect, which is worth popularizing.
