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 + 26.29); (26.29 + 1.97vs.83.60)

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 promotes the theoretical and overall teaching effect

which is worth popularizing.
