Computer-assisted instruction in radiology.

We developed an interactive computer system to support various educational uses. The system allowed numerous instructors to create lessons or tests in a flexible, personalized fashion. As a pilot project, the system was used to develop and administer a computer-driven final examination in a didactic radiology course for second-year medical students. It was our objective to change the examination into an enjoyable experience that would also bring about long-term learning gains. The computer added immediate feedback to the testing situation.
