A computer analysis of the compositions written by university students with (N=30) and without (N-60) learning disabilities (LD) found LD students were not as fluent in word production and in the number of different words used but did produce longer sentences and T-units than nondisabled peers. (DB)

Evaluated the effectiveness of vocabulary computerized adaptive tests (CATs) with restricted review in a live testing setting involving 242 college students in which special efforts were made to increase test efficiency and reduce the possibility of obtaining positively biased proficiency estimates. Results suggest the efficacy of allowing limited…

Compared results from computerized vocabulary tests under conditions in which item review was permitted or not permitted. Results from 177 college students reveal that performance gains after review were greater for examinees of high ability, and that review was desired more by examinees with higher test anxiety. The major drawback to review was…

Studied effects of administration mode [computer adaptive test (CAT) versus self-adaptive test (SAT)], item-by-item answer feedback, and test anxiety on results from computerized vocabulary tests taken by 293 college students. CATs were more reliable than SATs, and administration time was less when feedback was provided. (SLD)

Describes a computer-based methodology that obtains simple timed responses to sets of words and word-like nonsense items, then presents pilot data depicting estimated vocabulary knowledge and relating it to word frequency and decision response time. (FL)

Vocabulary fixed-item (FIT), computerized-adaptive (CAT), and self-adapted (SAT) tests were compared with 121 college students. CAT was more precise and efficient than SAT, which was more precise and efficient than FIT. SAT also yielded higher ability estimates for individuals with lower verbal self-concepts. (SLD)

Undergraduate students were administered one of three conventional or one of three stratified adaptive vocabulary tests with or without knowledge of results. Results indicated that knowledge of results and test difficulty affected performance. (Author/JKS)
