The Joreskog and Sorbom LISREL (linear structural relations) method is investigated as an alternative to regression analysis in studies of aptitude-treatment interactions (ATI), to solve problems caused by unreliability of measurements and by large sets of variables. A study reported by M.J. Behr is reanalyzed. This study investigated relations…

Transformation abilities are those which deal with the intellectual process of changing, revising, or redefining information. Scores on a measure of academic learning were found significantly related to several of these transformation ability factors. (DG)

A model demonstrates how low correlations for academic achievement in separate units of instruction can be compatible with high correlations for cumulated achievement. The unit achievement is assumed to consist of a task-specific part and a part correlated with a predictor. When units of learning are cumulated, attrition of earlier learning takes…

Factors which appear to affect learning are reviewed: student characteristics of age, ability, and motivation; amount and quality of instruction; home and classroom environment; peer influence; television; school and principal effects; and financial expenditures. (GDC)

Students enrolled in an organic chemistry course were given a diagnostic inventory according to the SCRAPE model. Information was obtained on 11 motivational personality variable and three attitudinal variables for students in both computer-based instruction and regular instruction sections.

The focus is on providing instruction to students from the orientation of educational psychology and in the context of elementary schools for students from low socioeconomic status…
