Comparability of Testing Using Laptop and Desktop Computers.
Powers, Donald E.; Potenza, Maria T.
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 be affected by monitor size and the additional scrolling needed for a laptop. Subjects were 201 paid volunteer graduate students and upper-level undergraduates on 9 university campuses, all of whom had at least minimal typing skills. Usable data were available for 200 subjects on the verbal and quantitative tests and 199 on the writing portion. All subjects participated with both types of computer. Analyses of test scores indicate that only performance on the essay section was affected by the type of computer used, and only for the first of two essays. The reason for the interaction of mode with order of testing was not evident, although fatigue may have modified the results of the second essay, which was written after earlier testing. The laptop model used in this study appears likely to yield results that are comparable to those obtained with a standard desktop model. (Contains seven tables and two references.) (SLD)
