Application of case-based PBL teaching in the postgraduate education of radiography / 中华医学教育探索杂志

ABSTRACT

Objective:To observe the application of case-based problem-based learning (PBL) teaching in the postgraduate education of radiography.Methods:A total of 48 postgraduates in the Batch 2019/2020 of professional masters majoring in radiography were selected as research objects, and they were divided into observation group ( n=24, Batch 2020) and control group ( n=24, Batch 2019). The students in the control group were taught by traditional teaching, and the students in the observation group were taught by case-based PBL teaching method. The differences in imaging diagnosis level and structured assessment scores of the two groups of students and their evaluation of the teaching process were analyzed. SPSS 20.0 was applied to perform the t test and chi-square test. Results:The imaging diagnosis ability of the students in the observation group (84.98±7.51) was significantly higher than that in the control group (78.21±6.96) , and the difference was statistically significant ( P<0.05). The students in the observation group had higher ability of imaging diagnosis skills and case analysis and diagnosis during the structured assessment ( P<0.05). The students in the observation group had higher overall satisfaction with the teaching process than those in the control group ( P<0.05). Conclusion:The case-based PBL teaching is of great help in improving the clinical thinking and imaging diagnosis ability of postgraduates majoring in radiography. In the application, it is necessary to continuously improve and supplement the teaching implementation plan according to the teaching evaluation and feedback.
