On-line vs. written multiple-choice questions tests: accuracy and usefulness

With the on-line resources becoming common one can ask what are the limitations when applied to online examinations. Standardized multiple-choice questions test are commonly used either as a tool to enable student selfexamination or as a tool to test a large number of students in a more efficient way. However, the means of delivery and what one intends the tests to measure should be carefully considered. During last two years in teaching the course “ Signals and System” both on-line and written, proctored and non-proctored multiple-choice questions test were used in production environment (in vivo). Obtained data suggest that test delivery method strongly influences test accuracy when measuring the knowledge students gained. On-line nonproctored delivery, although being the simplest, yields strongly biased results and is suitable only as a tool to enable student self-assessment of the knowledge gained, while the on-line or written (non-strictly) proctored tests are still the method of choice is ones wants to objectively measure the knowledge students gained.
