| 抄録: | Computer-assisted testing applications have proliferated in recent years. Despite the dramatic growth in the number of tests that have undergone computer conversion, there is little research data to justify the use of computers. Few studies have been conducted wherein the researchers specifically examined the issue of parity between computerized and conventional forms. Studies are required to determine whether the differences incurred as a result of the conversion process are significant enough to jeopardize the integrity of tests. The primary purpose of this research was to examine the equivalency issue in the area of aptitude testing. Specifically, the study objective was to investigate whether significant differences existed in mean aptitude test scores when subjects were administered the conventional and computerized adaptive versions of the Differential Aptitude Tests (DAT). A secondary purpose was to determine the degree that ancillary factors (e.g., computing experience) influenced performance on the computerized version. The sample consisted of 40 high school freshman. The statistical tests used to investigate the research objectives were the Spearman-Rho rank order correlation, analysis of variance, Dunn's test, Kolmogorov-Smirnov goodness-of-fit test, and linear regression. The computerized adaptive version of Form V of the DAT was found to be equivalent to the conventional Form V of the DAT for seven of the eight subtests. The two versions of the DAT had equivalent mean scores, comparable shapes of distributions of the scores, and similar rank order of individual scores. The subtest for which equivalency was not established was the clerical speed and accuracy subtest. Despite the overall comparability between versions, the ancillary factors of computing experience and attitude toward computers were found to correlate with performance on the computerized version. Typing experience, however, was not found to correlate with computerized test performance. In this experiment the suitability of assessing one's aptitude through computerized adaptive testing was confirmed. The findings lead one to conclude, however, that while the majority of the aptitude tests incurred only minor changes as a result of the conversion process, not all conventional tests may be candidates for computer conversion. |
