ABSTRACT

Objective:To explore the applicability and application effect of formative evaluation in mind mapping combined with PBL in the teaching of medical imaging.Methods:A total of 155 students majoring in clinical medicine (general practice) from the fifth clinical college of Chongqing Medical University were recruited in the study, 56 of which were divided in the experimental group and 99 students in the control group, using mind mapping combined with PBL teaching method to carry out medical imaging practice classes. The experimental group were given formative evaluation and questionnaire survey. SPSS 20.0 was used to conduct t test and variance analysis. Results:The questionnaire indicated that 66.0% (37/56) of the students were in favor of the formative evaluation with a Likert score of (4.0±0.7). While the experimental group was superior to the control group in the review test, with statistical significance ( P<0.05). There was no significant difference in the final scores between the experimental group and the control group ( P>0.05), but the results of case-analysis questions in the experimental group were better than those in the control group ( P<0.05). Conclusion:Formative evaluation is applicable to mind mapping combined with PBL in the teaching of medical imaging, which can thoroughly evaluate students' comprehensive ability and quality, improve their sense of self-efficacy, and constantly provide motivation for their learning.
