A conventional vocabulary test and two forms of a stradaptive vocabulary test were administered by a time-shared computer system to undergraduate college students. The two stradaptive tests differed in that one counted question mark responses (i.e., omitted items) as incorrect and the other ignored items responded to with question marks.…

This study empirically investigated the validity and utility of the stratified adaptive computerized testing model (stradaptive]developed by Weiss (1973). The model presents a tailored testing strategy based on Binet IQ measurement theory and Lord's (1972) modern test theory. Nationally normed School and College Ability Test Verbal analogy items…

Subjects ranging from preschoolers to professors were asked to choose between pairs of stimulus pseudowords, the one most like a given target word. Unidimensional scale analysis, item analysis, and factor analysis of the data resulted in the following findings: (1) Adults showed a dominant preference to "addition" errors as opposed to errors of…

The model described in this paper for the teaching of beginning shorthand through the use of computer-assisted instruction attempted to prevent incorrect responses from occurring during the acquisition of correct responses to beginning shorthand symbols. (Author)

Classification studies are important for practitioners who need to identify individuals for specialized treatment or intervention. When interventions are irreversible or misclassifications are costly, information about the proficiency of different classification procedures becomes invaluable. This study furnishes information about the relative…

The study evaluated the comparability of two versions of a teacher certification test: a paper-and-pencil test (PPT) and computer-based test (CBT). Standardized mean difference (SMD) and differential item functioning (DIF) analyses were used as measures of comparability at the test and item levels, respectively. Results indicated that effect sizes…

The study compared two promising item response theory (IRT) item-selection methods, optimal and content-optimal, with two non-IRT item selection methods, random and classical, for use in fixed-length certification exams. The four methods were used to construct 20-item exams from a pool of approximately 250 items taken from a 1985 certification…

Four item bias methods were studied. The methods compared include the Mantel-Haenszel statistic, the plot method, the route mean squared difference method, and the total area method; the latter two methods are based on item response theory. The test consisted of item responses of 451 male and 486 female ninth graders to 75 test items on the 1985…

THE JUDGMENTS OF TEACHERS AND THEIR REACTIONS TO THE EXPERIMENTAL MATHEMATICS PROGRAMS THEY WERE TEACHING IN CONNECTION WITH A PROJECT WHICH EVALUATED SEVERAL RECENTLY DEVELOPED PROGRAMS WERE OBTAINED AND ANALYZED. OBSERVATIONS AND JUDGMENTS ABOUT THESE PROGRAMS WERE OBTAINED THROUGH A QUESTIONNAIRE SENT TO TEACHERS WHO PARTICIPATED IN ONE OF THE…

Uses item analysis techniques to compare two multiple-choice test formats for assessing second language students' competence in English structure in terms of mean scores, item difficulty, and item discrimination. Findings reveal that difficulty and discrimination aspects are item-specific rather than format-dependent and items with moderate…

This paper presents an introduction to the use of latent trait models for the estimation of domain scores. It was shown that these models provided an advantage over classical test theory and binomial error models in that unbiased estimates of true domain scores could be obtained even when items were not randomly selected from a universe of items.…

A study investigated the effects of specific guidelines in the taking and rating of tests of summarizing ability. The subjects were 63 native-Hebrew-speaking students enrolled in English-as-a-Second-Language (ESL) courses at the Seminar Hakibbutzim Teacher Training College in Tel Aviv (Israel). The subjects were given two sets of instructions…

The content of selected major achievement tests is examined for bias in the frequency of references to the male and the female sex. The performance of males and females is contrasted on each item considered, and the relationships between item content and the performance differences is surveyed. The tests used in this study include the Metropolitan…

Three methods of item selection were used to select sets of 38 items from a 50-item verbal analogies test and the resulting item sets were compared for internal consistency, standard errors of measurement, item difficulty, biserial item-test correlations, and relative efficiency. Three groups of 1,500 cases each were used for item selection. First…

The current study is concerned with identifying racial-ethnic differences in cognitive strategies or structures that are related to performance on verbal ability tests. The study had two goals: (1) to compare the semantic equivalency of intelligence test items between racial-ethnic groups, and (2) to examine the relationships of individual…
