Predicting Achievement in Secondary Mathematics Courses.
Pinkham, Andrea K.; Ansley, Timothy N.
The usefulness of the Iowa Algebra Aptitude Test (IAAT) as a predictor of student achievement in secondary mathematics courses was studied. Subjects were 977 students from 7 Iowa schools in grades 6 through 9. Data collected included their IAAT scores and Iowa Tests of Basic Skills (ITBS) mathematics skills test scores, as well as data about mathematics classes taken and grades received. Using multiple regression analysis, these factors were studied as predictors of achievement. It was found that the IAAT can be an important measure to use in predicting mathematics grades. Among predictors, current mathematics grade was most highly correlated with previous mathematics grades, as expected. The ITBS was correlated only slightly higher than the IAAT with mathematics grades for all subgroups and the total, but the IAAT was preferred in a stepwise regression when both test scores and previous mathematics grades were considered. Schools with both previous grades and the IAAT available gained only a small portion of useful information from IAAT scores for placement decisions. Discriminant analysis revealed that using a combination of previous mathematics grades and IAAT scores results in the most accurate and efficient classification.
