description- – This article describes selected results from the Math Online (MOL) study, one of three field investigations sponsored by the National Center for Education Statistics (NCES) to explore the use of new technology in NAEP. Of particular interest in the MOL study was the comparability of scores from paper- and computer-based tests. A nationally representative sample of eighth-grade students was administered a computer-based mathematics test and a test of computer facility, among other measures. In addition, a randomly parallel group of students was administered a paper-based test containing the same math items as the computer-based test. Results showed that the computer-based mathematics test was significantly harder statistically than the paper-based test. In addition, computer facility predicted online mathematics test performance after controlling for performance on a paper-based mathematics test, suggesting that degree of familiarity with computers may matter when taking a computer-based mathematics test in NAEP.

Two essay prompts were given on paper to a nationally representative sample as part of the 2002 main NAEP writing assessment. The same two essay prompts were subsequently administered on computer to a second sample also selected to be nationally representative. Analyses looked at overall differences in performance between the delivery modes, interactions of delivery mode with group membership, differences in performance between those taking the computer test on different types of equipment (i.e., school machines vs. NAEP-supplied laptops), and whether computer familiarity was associated with online writing test performance. Results generally showed no significant mean score differences between paper and computer delivery. However, computer familiarity significantly predicted online writing test performance after controlling for paper writing skill. These results suggest that, for any given individual, a computer-based writing assessment may produce different results than a paper one, depending upon that individual's level of computer familiarity. Further, for purposes of estimating population performance, as long as substantial numbers of students write better on computer than on paper (or better on paper than on computer), conducting a writing assessment in either mode alone may underestimate the performance that would have resulted if students had been tested using the mode in which they wrote best.
