A comparison of linear, fixed-form computer-based testing versus traditional paper-and-pencil-format testing in veterinary medical education

Computerized testing has made significant inroads into veterinary education. Traditional paper-and-pencil examination formats are being replaced by computer-based testing (CBT). Computer-administered, fixed-form tests, because they mimic most closely the familiar fixed-response paper-and-pencil test formats, might intuitively seem to be inherently equivalent to their paper-and-pencil counterparts. However, research examining test-mode effects on student performance presents a very mixed picture. Additionally, students often report that they feel their performance is adversely affected by CBT and that their grades on the computer-based exams are lower than they would have been on the more familiar paper-and-pencil format. In order to address student perceptions of negative impact and the mixed nature of the published research results on the topic, a study was conducted to assess whether the transition from paper-and-pencil to equivalent linear CBT exams did, in fact, affect students' examination scores. This study found no evidence for significant test-mode effects on student scores as a result of the introduction of computer-based testing into the veterinary curriculum.
