Eighteen undergraduates were given a standard manufacturing textbook and 18 a text in which major concepts were expressed as mathematical equations. The mathematical text enhanced ability to recall concepts and apply them in context. However, transfer of concepts to different concepts was not affected by type of text. (SK)

Normally achieving students (n=119) and students with mild handicaps (n=83) in grades 3-6 were instructed to create and answer computation items similar to samples given. Students with mild handicaps understood item characteristics enough to create like items, though averaging three years behind normal achievers. A sample instructional activity is…

Statistical analysis of racially polarized voting prepared for the Garza v County of Los Angeles (California) (1990) voting rights case is reviewed to demonstrate that ecological regression is a flexible, robust technique that illuminates the reality of ethnic voting, and superior to the neighborhood model supported by the defendants.

Charleston (South Carolina) Southern University has developed a summer enrichment program for gifted and motivated middle school students focusing on the science-based and mathematics-based professions, especially engineering and research. The program provides special motivational advantages to young girls through individual attention and…

Describes the design of a prototypical computer-mediated communication (CMC) system at the Open University of the Netherlands called StudieNet which focuses on a single mathematics course. The concept of the integrated study environment used in StudieNet is explained, StudieNet functions are compared with the nonautomated course, and how the…

Presents the results of a United Kingdom study comparing computer anxiety, mathematics anxiety, and computer experience among college students and elementary students. Includes discussion of age, sex, and the relationship between anxiety and experience. Reports that the younger children had higher computer experience and less computer anxiety.…

Forming the matching variable for the Mantel-Haenszel differential item functioning (DIF) procedure through use of the total score as the matching variable (thin) and forming the matching variable by pooling total score levels (thick) were compared in a Monte Carlo study. Reasons thick matching is superior are discussed. (SLD)

Reevaluates statistical studies by G. Galster (1986, 1987, 1988) and Galster and W. Keeney (1988) of segregation in housing, reanalyzing one of four model equations. The effects of discrimination are smaller than postulated previously. Direct estimates from housing discrimination surveys provide a rationale for these smaller effects. (SLD)

Seventh-grade students (n=397) were studied to determine the effect on immediate achievement and retention of a unit designed to promote the development of estimating skills involved in metric measuring. Identical metric instruction was used with the exception of activities in estimation for the treatment group. The treatment group retained…

Analyzes effect sizes in tails of distribution of scores in Feingold's study of joint effects of gender differences in mean and variability on 28 cognitive-ability scales. Effect sizes are smaller than Feingold assumed. Evaluates joint effect of gender differences by number of males and females in extreme score ranges. (SLD)

This study compared psychoeducational characteristics of 67 children (ages 6-16) with Turner syndrome and 27 nonaffected controls. Subjects exhibited selective impairments in visuospatial and memory areas; significant underachievement in arithmetic; poor social competence; and increased behavior problems, particularly in the area of hyperactivity.…

An examination of constructivist learning and teaching theory and its current popularity looks at previously popular theories, implementation problems, classroom experiments using constructivism, and the roles of teacher and learner under this approach. Discussion is confined to mathematics instruction and the mathematics classroom. (Author/MSE)

Describes a three-day course offered by British consultants to train key education officers and teacher advisor-trainers in Botswana in observational and interaction skills as part of an effort to improve primary education in the country. Details the instructional content of each day of the course devoted to ice-breaker activities, math…

This paper illustrates how, in the item-response theory framework, collateral information about test items can augment or replace examinee responses when linking or equating new tests to established scales, using data from the Pre-Professional Skills Test for approximately 40,000 examinees. Collateral information can predict item operating…

Children and adults were tested on six speeded perceptual-motor and cognitive tasks, including a (1) response time task; (2) button tapping task; (3) pegboard task; (4) coding task; (5) picture matching task; and (6) mental addition task. Age-related change in processing time on most of these tasks was described by a single exponential function.…
