Unlike the traditional multiple-choice (MC) format, the discrete-option multiple-choice (DOMC) format does not necessarily reveal all answer options to an examinee. The purpose of this study was to determine whether the reduced exposure of item content affects test security. We conducted an experiment in which participants were allowed to view…

A decision of whether to move from paper-and-pencil to computer-based tests is based largely on a careful weighing of the potential benefits of a change against its costs, disadvantages, and challenges. This paper briefly discusses the trade-offs involved in making such a transition, and then focuses on a relatively unexplored benefit of…

Two types of answer-copying statistics for detecting copiers in small-scale examinations are proposed. One statistic identifies the "copier-source" pair, and the other in addition suggests who is copier and who is source. Both types of statistics can be used when the examination has alternate test forms. A simulation study shows that the…

A solution to reduce the likelihood of one examinee copying another's answers on large scale tests that require all examinees to answer the same set of questions is to use multiple test forms that differ in terms of item ordering. This study was conducted to determine whether varying the sequence in which blocks of items were presented to…

Compares the effect of content ordering and scrambled ordering on examinations in courses, such as economics, that require quantitative skills. Empirical results suggest that students do no better if they are given a content-ordered rather than a scrambled examination as student performance is not adversely affected by scrambled ordered…

Investigates the effects on multiple choice test performance of altering the order and placement of questions and responses. Shows that changing the response pattern appears to alter significantly the apparent degree of difficulty. Response patterns become more dissimilar under certain types of response alterations. (LS)
