Examined whether providing item review on a computerized adaptive test could be used by examinees to inflate their scores. Two studies involving 139 undergraduates suggest that examinees are not highly proficient at discriminating item difficulty. A simulation study showed the usefulness of a strategy identified by G. Kingsbury (1996) as a way to…

An experiment was conducted that contrasted a variant of computerized adaptive testing, self-adapted testing, with two traditional tests. Participants completed a self-report of text anxiety and were randomly assigned to take one of the three tests of verbal ability. Subjects generally chose more difficult items as the test progressed.

Computer adaptive testing is the study of scoring tests and questions based on assumptions concerning the mathematical relationship between examinees' ability and the examinees' responses. Adaptive student tests, which are based on item response theory (IRT), have many advantages over conventional tests. We use the least square method, a…

The degree to which item review on a computerized adaptive test (CAT) could be used by examinees to inflate their scores artificially was studied. G. G. Kingsbury (1996) described a strategy in which examinees could use the changes in item difficulty during a CAT to determine which items' answers are incorrect and should be changed during item…

In self-adapted testing (SAT), examinees select the difficulty level of items administered. This study investigated three variations of prior information provided when taking an SAT: (1) no information (examinees selected item difficulty levels without prior information); (2) view (examinees inspected a typical item from each difficulty level…

No significant differences in performance on a self-adapted test or anxiety were found for college students (n=218) taking a self-adapted test who selected item difficulty without any prior information, inspected an item before selecting, or answered a typical item and received performance feedback.

Previous studies have shown that, when administered a self-adapted test, a few examinees will choose item difficulty levels that are not well-matched to their proficiencies, resulting in high standard errors of proficiency estimation. This study investigated whether the previously observed effects of a self-adapted test--lower anxiety and higher…

According to item response theory (IRT), examinee ability estimation is independent of the particular set of test items administered from a calibrated pool. Although the most popular application of this feature of IRT is computerized adaptive (CA) testing, a recently proposed alternative is self-adapted (SA) testing, in which examinees choose the…

In self-adapted testing, examinees are allowed to choose the difficulty of each item to be presented immediately before attempting it. Previous research has demonstrated that self-adapted testing leads to better performance than do fixed-order tests and is preferred by examinees. The present study examined the strategies that 29 college students…

Computerized adaptive (CA) testing uses an algorithm to match examinee ability to item difficulty, while self-adapted (SA) testing allows the examinee to choose the difficulty of his or her items. Research comparing SA and CA testing has shown that examinees experience lower anxiety and improved performance with SA testing. All previous research…

Volunteer college students were assigned to one of six computer administered vocabulary tests, one half with immediate knowledge of results (KR) after responding to each item, and the other half without knowledge of results. The six tests were designed to be at one of three levels of difficulty and consisted either of 50 preselected items…

Two types of computer-administered unit quizzes in a systematic pathology course for second-year medical students were compared. Quizzes composed of questions selected on the basis of a student's ability had higher correlations with the final examination than did quizzes composed of questions randomly selected from topic areas.

The strategies examinees employ when making item difficulty level choices in self-adapted computerized testing were investigated. Subjects were 148 college students (88 females and 60 males) in an introductory statistics course. The primary instrument was a self-adapted computerized algebra test used to measure student readiness for the statistics…

Effects of altering test difficulty on examinee ability measures and test length in a computer adaptive test were studied for 225 medical technology students in 3 test difficulty conditions. Results suggest that, with an item pool of sufficient depth and breadth, acceptable targeting to test difficulty is possible. (SLD)

The effects of review options (the opportunity for examinees to review and change answers) on the magnitude, reliability, efficiency, and concurrent validity of scores obtained from three types of computerized vocabulary tests (fixed item, adaptive, and self-adapted) were studied. Subjects were 97 college students at a large midwestern university…
