Abstract:
Objective A study was performed to better define the teaching outcome of computers in teaching medical imaging. Methods 150 4rd-year students were randomly assigned to four groups and experimental group exposed to 20 radiology cases as well as to a voluntary weekly radiology lecture. Group A used computer-based cases with interactive elements; group B used computer-based cases without interactive elements; group C used paper-based cases with interactive elements; and group D was not exposed to the cases and served as a control group. Results On a multiple-choice question test,groups A,B,and C showed significant improvemen(t+10.6%,+15.7%,+13.5%,respectively),whereas group D did not(+2.7%). On an image interpretation test,group A and group B showed the most improvement (+15.8%,P
