Research design and data analysis recommendations address aptitude distributions, multivariate aptitude complexes, detective work with scatterplots,…

Testing and studying of 373 college students enrolled in an introductory five credit-hour course in data processing indicated that a very large proportion of the students appeared to possess sufficient aptitude for computer programming training.

Foreign language aptitude was the subject of much research in the 1950s and has been the subject of intermittent research for the last 30 years. Aptitude is measured by the amount of time it takes an individual to learn. Foreign language aptitude appears to differ from general aptitude or intelligence. One theory states that foreign language…

The literature on medical education does not contain many studies directly concerning ATI (Aptitude-Treatment Interaction) or more broadly TTI (Trait-Treatment Interaction), in spite of the great many studies on the characteristics of medical students. Nevertheless, a project at Michigan State University was begun in which an entry profile of all…
