BackgroudIn the field of medical education, the innovation and optimization of teaching methods have always been the key to improving the quality of education. The popularization of the WeChat platform has provided a broader application space for question banks, especially digital question banks. To improve the teaching quality of pediatric surgery, a digital question bank for pediatric surgery was constructed based on the WeChat platform and applied to the clinical teaching of pediatric surgery. We explore whether integrating the digital question bank into the WeChat platform can help improve examination scores and also explore students' satisfaction.MethodsIn this study, a clinical question bank covering pediatric surgery was established and then entered into the WeChat Official Accounts Platform. The instructor guides the medical students to use the WeChat platform for daily teaching activities and to complete the assessment of the digital question bank. A relevant evaluation system was established based on the big data results provided by the WeChat Official Account. This evaluation system was composed of the evaluation of instructors for the learning initiative and knowledge mastery of medical students and the evaluation of medical students for the teaching level of instructors and the digital question bank pattern.ResultsA digital question bank of pediatric surgery was successfully established. A total of about 3,200 questions in the question bank were uploaded to the WeChat Official Account of the pediatric surgery department of Qilu Hospital of Shandong University. Based on the digital question bank, partial clinical teaching tasks of pediatric surgery were completed, and the learning effects of medical students were evaluated. The question bank exhibited a favorable difficulty coefficient and discrimination, and the examination scores conformed to the normal distribution, indicating the higher scientific and effectiveness of this question bank. The questionnaire survey results demonstrated that most medical students maintained that the application of the new question bank based on the WeChat Official Accounts Platform can increase their learning interest in pediatrics, cultivate their clinical thinking, and enhance their clinical ability.ConclusionA digital question bank of pediatric surgery was established for the first time based on the WeChat Official Accounts Platform. This digital question bank can be employed to evaluate the learning effects of medical students more scientifically, which contributes to improving teaching quality and teaching management. Overall, the new pediatric surgery question bank and the WeChat Official Accounts Platform can satisfy the development demands of pediatric surgery in the new era, exhibiting broad application prospects.
