Attempted to improve the measurement quality of a complex performance assessment through principled assessment design using the example of the National Board for Professional Teaching Standards Early Childhood/Generalist examination. All indexes examined improved after revisions were made. Results show the importance of attention to assessment…

Summarizes data related to the stability and variation in the norms for the Raven's Progressive Matrices Test (J. Raven, 1936), a measure of basic cognitive functioning, for different cultural, ethnic, and socioeconomic groups worldwide and within countries. Also considers variation over time and suggests an explanation for the variation in norms…

Studied modeling individual latent growth curves of older adults on measures of fluid intelligence by fitting second-order polynomial curves reflecting initial test performance improvement followed by relative stability/drop to the recorded scores of each of 248 subjects. Results suggest substantial plasticity in fluid intelligence of older…

Difficulties inherent in differentiating practice effects from meaningful change in neuropsychological retest data are illustrated in this case study of a personal injury case. Although the patient demonstrated substantial gains on the Wechsler Adult Intelligence Scale Revised, most of the tests given on successive days did demonstrate acceptable…

For paired rankings data, a statistical test is proposed to detect whether subjects' posttreatment rankings have moved systematically toward an unknown ranking or set of rankings. Using paired-rankings from 38 ninth graders in a writing and literary criticism course, graphical methods for representing the data are presented. (SLD)

Changes in verbal, spatial, and reasoning intelligence among Swedish 13-year olds were studied from 1960 to 1990. Rising verbal scores until 1980 have been followed by a decline to essentially the 1960 level. Spatial and reasoning results have risen continuously. Gender and social class differences are discussed. (SLD)

Effects of the policy of mandated busing for integration on overall achievement test scores of African-American children were studied with 434 elementary school students in Norfolk (Virginia). Achievement test scores declined after the elimination of mandated busing. School characteristics explained 9% of the variance in scores for all students.…
