Estimated year-to-year changes in average writing performance for 188 schools using a group-level version of the generalized partial credit item-response theory model. Results illustrate that technical equating adjustments can be important even when there have been rigorous efforts to make prompts and rating training equivalent to the old tests.…

The dimensionality of students' attitudes toward regular classroom activities and enrichment clusters were studied with 379 urban elementary school students using two instruments developed for the study. Analyses allowed examination of the construct validity of the scores from both measures while indicating that derived factors were not the same…

Data from 196 Irish school children were analyzed and used to develop a shortened version of the Fennema-Sherman Mathematics Attitudes Scales (E. Fennema and J. Sherman, 1976). Internal consistency estimates of the reliability of scores on the whole scale and each of the subscales of the original and short form were favorable. (SLD)

Three analytic approaches were used in a framework of classical test theory to examine the construct validity of a mathematics assessment of 16 constructed response items. Results from 280 elementary school students across four age groups suggest a developmental structure of tasks and subdomains that was generally consistent with the test's…

Applied factor analysis to the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores for 505 gifted students, to evaluate the construct validity of the WISC-III with this population. Results are consistent with the hypothesis that subtests that emphasize speed of reading are not valid for gifted children and suggest that an…

Studied the interpretation of scores on the Kaufman Ability Battery for Children(K-ABC) (Kaufman and Kaufman, 1983) as a measure of "Pure" intelligence in the Israeli standardization sample of 1,600 students in kindergarten through grade 8. Schooling was found to affect raw scores on all K-ABC mental processing scores, and the effects of…

Used a multitrait-multimethod approach to investigate the validity of scores on locally prepared performance assessments taken by 6,000 third and fourth graders in reading, language arts, and mathematics. A partial explanation for the lack of construct validity evidence for the performance assessment scores is the probable low reliability of…

The present study compares vertical scaling results for the Rasch model from BILOG-MG and WINSTEPS. The item and ability parameters for the real and simulated mathematics tests were scaled across five grades, second to sixth. The simulated data were based on real data for a series of mathematics tests for Grades 2 to 6. The results from WINSTEPS…
