Interaction Effects Between Selected Cognitive Abilities and Instructional Treatment in Algebra: An ATI Study.
Webb, Leland F.
The purpose of this study was to confirm or deny Carry's findings in an earlier Aptitude Treatment Interaction (ATI) study by implementing his suggestions to: (1) revise instructional treatments, (2) improve the criterion measures, (3) use four predictor tests, (4) add time to criterion measure, and (5) use a theoretical model to identify relevant variables within each treatment. A pilot study of 77 students was used to decide that only a transfer test and time to criterion measure would be used. The final study involved 249 second-year algebra students in Waco, Texas, randomly assigned to either an analytical or a graphical treatment. Four classroom periods were used for the study. The treatments were found equally effective, with no interactions between any aptitude variable and either treatment. Item analysis produced no class of transfer test items exhibiting ATI. Thus, the study was inconsistent with Carry's, and ATI's are concluded to be more complex than originally believed. Recommendations for future ATI studies include use of many varied criterion measures, a study of differential aptitude variables, item analysis for consistency of transfer and retention tests before use of the scores, and development of homogeneous tests and longer instructional treatments.
