The Effect on Pupil Performance of Using Hand-Held Calculators on Standardized Mathematics Achievement Tests.
Lewis, Janice; Hoover, H. D.
Students in grades four and eight were given parallel forms of mathematics subtests of Iowa Tests of Basic Skills, once using calculators and once without. Performance with calculators was compared to performance on regular administration of subtests. In both grades, mean scores on problem solving and computation subtests were significantly higher with calculators, but no difference was found for the concepts subtest. Largest differences appeared on computation subtests. For fourth grade, significant improvement in subtraction and multiplication occurred with calculators. Eighth graders' performance on whole number and decimal operations was significantly improved by using a calculator, but their performance on operations involving fractions was significantly worse with calculators. In both grades, students completed fewer items on the computation and problem-solving subtests when they used calculators. Correlations between scores on the two testings were computed for the three subtests. After correction for restriction in range and attenuation, the resulting correlations ranged from .79 to .99 for fourth grade and from .96 to 1.0 for eighth grade. This suggests that if the tests were standardized with calculators, the rankings of students, at least in eiqhth grade, would be the same as the rankings given by the present mathematics subtests.
