A Study of the Predictive Validity of the Iowa Algebra Aptitude Test for Prognosis in Ninth Grade Modern Mathematics and Traditional Algebra.
Sabers, Darrell Lee
There were three objectives of a revision and validation of the Iowa Algebra Aptitude Test (IAAT): (1) to reduce the importance of speed; (2) to improve the quality of the existing items; and (3) to replace a subtest with one of potentially greater predictive validity. The last of these goals involved the development of a new subtest composed of a series of short math lessons. On the basis of 1,943 eighth grade students' scores on the IAAT and their grades in mathematics, it was found that the IAAT is a highly reliable (.94) and relatively valid instrument for prognosis in both algebra and modern mathematics.
