Equivalency of computer-based and paper-and-pencil testing

This study examined the equivalence of computer- and paper-based versions of an examination through score differences across the two test formats as well as students' attitudes toward and perceptions of computer-based examinations. Thirty senior dental hygiene students were randomly divided into two equal groups. One took the first examination on computer, while the second took it on paper. Later, the groups were switched for a second examination. In completing the computer version, each student was asked to complete a survey that examined his or her experience with as well as attitude and perceptions toward computer-based testing. Students using the computer performed as well as or better than those using paper; the increase in performance was significant for the first examination (p < 0.05). Student acceptance of the computer format was mixed, possibly varying with prior exposures to such formats. Benefits of the computer-based examination included reduction in time required for scoring and recording of grades, quicker student progression through the examinations afforded by the digitizing of the visuals, and ease of item analysis for both individual students and the group.
