Exploratory and confirmatory factor analyses of domestic data from the" GRE"® revised General Test, introduced in 2011, were conducted separately for the verbal (VBL) and quantitative (QNT) reasoning measures to evaluate the unidimensionality and local independence assumptions required by item response theory (IRT). Results based on data…

Data from 181 college students were used to assess whether math reasoning item response times in computerized testing can provide valid and reliable measures of a speed dimension. The alternate forms reliability of the speed dimension was .85. A two-dimensional structural equation model suggests that the speed dimension is related to the accuracy…

The degree to which laptop and standard-size desktop computers are likely to produce comparable test results for the Graduate Record Examination (GRE) General Test was studied. Verbal, quantitative, and writing sections of a retired version of the GRE were used, since it was expected that performance on reading passages or mathematics items might…

This report summarizes the results from two studies. The first assessed the comparability of scores derived from linear computer-based (CBT) and computer adaptive (CAT) versions of the three Graduate Record Examinations (GRE) General Test measures. A verbal CAT was taken by 1,507, a quantitative CAT by 1,354, and an analytical CAT by 995…

This study investigated the transfer of solution strategies between close variants of quantitative reasoning questions. Pre- and posttests were obtained from 406 college undergraduates, all of whom took the same posttest; pretests varied such that one group of participants saw close variants of one set of posttest items while other groups saw…

This study evaluated agreement between expert system and human scores on 12 algebra word problems taken by Graduate Record Examinations (GRE) General Test examinees from a general sample of 285 and a study sample of 30. Problems were drawn from three content classes (rate x time, work, and interest) and presented in four constructed-response…

Specific questions addressed in this study include how time limits affect a test's construct and predictive validities, how time limits affect an examinee's time allocation and test performance, and whether the assumption about how examinees answer items is valid. Interactions involving an examinee's sex and age are studied. Two parallel forms of…

Two computer-based categorization tasks were developed and pilot tested. In study 1, the task asked examinees to sort mathematical word problem stems according to prototypes. Results with 9 faculty members and 107 undergraduates showed that those who sorted well tended to have higher Graduate Record Examination General Test scores and college…

Examinees in a regular administration of the quantitative portion of the Graduate Record Examination responded to particular items in a machine-scannable multiple-choice format. Volunteers (n=364) used a computer to answer open-ended counterparts of these items. Scores for both formats demonstrated similar correlational patterns. (SLD)
