Abstract:
Objective:To investigate the application value of WeChat-based problem-based learning teaching method combined with micro-classroom in the teaching of contrast-enhanced gastrointestinal ultrasound imaging for residents in standardized residency training.Methods:A total of 40 trainees who underwent the standardized residency training in the Department of Ultrasound, The First Affiliated Hospital of Chongqing Medical University from January 2019 to June 2021 were selected as the research objects. They were randomly divided into the experimental group (WeChat-based PBL teaching method combined with micro-classroom) and the control group (traditional teaching method). The teaching content was the diagnosis of gastrointestinal ultrasound imaging. After the theoretical learning and practice, assessments of contrast-enhanced gastrointestinal ultrasound imaging including theory and operating practice were performed to all students. SPSS 22.0 was used for t test and rank sum test.Results:After training, the theoretical test scores of the experimental group were higher than those of the control group [(93.09±2.31) vs. (90.63±2.26)], and the difference was statistically significant ( P<0.05). However, there was no significant difference between the two groups in the number distribution of students at all levels of operational practice ( P>0.05). Conclusion:The WeChat-based PBL teaching method combined with micro-classroom is beneficial to improve students' knowledge of contrast-enhanced gastrointestinal ultrasound imaging, and is worth being popularized and applied in clinical teaching.
