Subjects were randomly assigned to two methods of instruction for a unit on quadratic inequalities. It was expected that spatial visualization scores would predict transfer from the analytic approach while general reasoning would predict transfer from the graphical approach. No interaction was found. (Author/SD)

A persistent problem in aptitude-treatment interaction (ATI) research has been the need for a better conceptualization of instructional treatments. The concerns are important in the analysis of instructional treatments: the importance of considering the psychological processes called upon by the instructional treatment, and the ecological validity…

Joreskog has developed a very general and powerful model and computer program for analyzing relationships among variables, called LISREL. Structural analysis of covariance matrices by Joreskog's LISREL method is proposed as an alternative to regression methodology in the analysis of aptitude-treatment interaction (ATI) data. LISREL resolves some…

This report is the second part of a study designed to construct a test for measuring musical aptitude of persons from various age groups. It covers the construction of the test, material, item analysis, reliability, validity, and possible future steps. The test is composed of musical recordings, determined from pilot studies, that the test groups…

The purpose of this study was to broaden the aptitude by treatment interaction paradigm. The relationship between memory span and performance in two different transfer conditions was examined, and task involvement and anxiety were considered as they contribute to the relationship between aptitudes and performance.

Aptitude-treatment interactions were examined in a study involving 264 first-grade pupils randomly assigned to groups receiving perceptual training, affective education, or a combination of both, or to a comparison group receiving no supplementary instruction. Aptitude was measured using a general measure of intelligence; achievement was assessed…

No significant interaction was found between two instructional treatments and two aptitude variables in this study, but they did find four disordinal interactions, two using one predictor variable and two using two predictor variables. (MN)

The authors propose an alternate method of individualizing college mathematics instruction which combines the aptitude-treatment interaction (ATI) approach and approaches emphasizing a variety of instructional formats. (MN)

Job analyses were compared with employees' self-ratings of abilities across 54 occupations. Participants totaled 2,272 workers (1,119 women and 1,153 men) who took the Career Decision-Making System as part of an effort to expand its concurrent validity evidence. The results supported the validity of self-assessment of aptitudes in career…

A study was done to determine the relationships between the revised Occupation Analysis Inventory (OAI) work-dimension scores and job ability-requirement estimates and the ability test scores of job incumbents and graduate trainees in related vocational/technical education programs. (The OAI is an instrument containing 622 work elements which are…

A study was undertaken to develop a system for predicting the impact of adjustments in aptitude requirements on outcomes (performance) in Air Force basic resident technical training. To accomplish this, a multivariate modeling approach was used. Initially, interviews were constructed within a variety of technical training programs to specify the…

A vast literature in educational psychology attests to the fact that individual differences in learner aptitudes predict learning outcomes. A substantial body of literature also demonstrates that aptitude variables often interact with instructional treatment variables in these predictions. Aptitude main effects and aptitude-instructional treatment…

The theoretical and methodological concepts for research on aptitudes as cognitive processes are discussed. Individual differences constructs are reviewed in relation to cognitive processing models, and studies of short-term memory are reviewed. A coordinated approach to the study of aptitude as information processing is recommended. (Author/RD)

The described program encourages high school students and teachers to come to a campus offering engineering and technology programs. During the one-day visit students compete in engineering aptitude tests and engage in career counseling activities. (RE)
