THE RELIABILITY AND VALIDITY OF AN INTERACTIVE ARITHMETIC TEST

A sample of 331 primary school children from seven primary schools, fr om Years 3 through 7, participated in this study to determine the reli ability of a computer resident interactive arithmetic test, using both the method of a single sitting and that of parallel forms. Reliabilit y coefficients up to .96 were calculated for scoring rates by the sing le sitting methods and up to .87 by the method of parallel forms. The study also attempted to determine the validity of the interactive test by comparing it with the arithmetic subtests of the I(ey Math Test (K MT, Connolly et al., 1971). Positive, but weak, correlations up to .65 were recorded, reflecting differences in the medium of administration and assessment methodology of the two tests.
