This paper summarizes an action research project to develop a math screening instrument that would be effective (valid and reliable) and efficient (time for administration). An instrument was developed after review of the mathematics assessment and mathematics disabilities literature. The instrument was administered to kindergarten, first, and…

The power of the procedure of W. Stout to detect deviations from essential unidimensionality in two-dimensional data was investigated for minor, moderate, and large deviations from unidimensionality using criteria for deviations from unidimensionality based on prior research. Test lengths of 20 and 40 items and sample sizes of 700 and 1,500 were…

The performance of the following four methodologies for assessing unidimensionality was examined: (1) DIMTEST; (2) the approach of P. W. Holland and P. R. Rosenbaum; (3) linear factor analysis; and (4) non-linear factor analysis. Each method is examined and compared with other methods using simulated data sets and real data sets. Seven data sets,…

A computer-administered version of the Yale-Brown Obsessive-Compulsive Scale was administered to 31 patients with obsessive-compulsive disorder, 16 with other anxiety disorders, and 23 nonpatient controls. The computer version correlated highly with the clinician-administered version and was well understood and liked by subjects. (SLD)

The mean scores of English Language Learners (ELL) and English Only (EO) students in 4th and 5th grade (N = 110), across the teacher-administered Grammar Skills Test, were examined for differences in participants' scores on assessments containing single-step directions and assessments containing multiple-step directions. The results indicated no…

Standard and experimental forms of the Johnson O'Connor Research Foundations Analytical Reasoning test were administered to 1,496 clients of the Foundation (persons seeking information about aptitude for educational and career decisions). The objectives were to develop a new form of the test and to better understand what makes some items more…

Over 2,000 writing samples were collected from four undergraduate institutions and compared, where possible, with scores on a multiple-choice test. High correlations between ratings of the writing samples and multiple-choice test scores were obtained. Samples contributed substantially to the prediction of both college grades and writing…

The purpose of this technical report is to describe the Tests of General Ability and Tests of Reading of the Inter-American Series, to give a brief account of their construction, and to present related statistical data. Norms and suggestions on the use and interpretation of the tests are published separately. The Inter-American Series discussed in…

A comparison is presented of alternate-choice and true-false item forms used in an undergraduate natural science course. The alternate-choice item is a modified two-choice multiple-choice item in which the two responses are included within the question stem. This study (1) compared the difficulty level, discrimination level, reliability, and…

Data from the Canadian Test of English for Scholars and Trainees (CanTEST) are compared to data from the Test of English as a Foreign Language (TOEFL) to establish CanTEST as a valid admissions tool for English-as-a-Second Language college applicants. Data are taken from four groups of examinees who took both tests. (eight references) (LR)
