Abstract
Background
Medical education in China is in a transitional period changing from passive learning to experiential education models. We have modified an experiential education method for radiology education. The aim of this study is to evaluate the effect of this method on undergraduate radiology education.
Methods
With the help of the picture archiving and communication system (PACS) and RadiAnt DICOM Viewer, we have modified an experiential education method that simulates similar working conditions for undergraduate medical students to take on the role as clinical radiologists and formulate radiology diagnosis. A total of 101 students were allocated into either the experiential education group [Office1] or the control group. The final examination scores and a 5-point Likert scale self-assessment questionnaire of radiologic skills were collected from all the students as an objective assessment and a subjective assessment respectively. A questionnaire was also used to assess the satisfaction with the experiential model in the experiential education group. Mann-Whitney U test was used to compare the ranked data, and t -tests were used to compare the numeric data.
Results
The experiential education group demonstrated significantly higher scores (7.4±1.3) in the short answer type questions on imaging “description and diagnosis” when compared to the control group (6.7±1.5, p <0.05). The self-assessment questionnaire indicated that the experiential education corresponded to an increased familiarity with the diagnostic principles, the imaging sequences and reconstruction methods of computer tomography (CT), which also strengthen participants’ confidence to perform future clinical work (p <0.05). The self-assessment questionnaire from the experiential education group showed great satisfaction with the organization (82.5%), interactivity (85%) and quality (85%) of the learning activity in majority of students. Most students found this model of learning to be helpful for studying radiology (85%) and for understanding anatomy (90%).
Conclusion
Compared with the traditional radiology education approach, the experiential education model showed greater efficacy in improving students’ analytical and diagnostic skills as well as clinical confidence.
