The problem of this study was to investigate the strategies used by high school students of limited estimation ability for the estimation of the answers to computational problems. The Assessing Computational Estimation Test was administered to 460 students, and 40 of them were selected for interviews. Each student interviewed was asked to estimate the answers to fourteen computation and application problems.

The purpose of this study was to test whether the computer-administered College Level Examination Program (CLEP) General Examination in English Composition produced scores equivalent to those obtained from the traditional paper-and-pencil version. The CLEP examination and its adaptation for computer administration and the results of a pilot study are presented. The subjects in this study were volunteers who took the CLEP English Composition Examination in order to earn college credit and were randomly assigned to either the computer-first or paper-and-pencil-first groups. Each subject took both forms of the examination with approximately one half of the subjects taking each version first. Analysis of variance failed to detect a significant effect for test form or an interaction of test form and order of administration. Equivalence reliability coefficients and internal consistency coefficients also indicated that the computer administration did not significantly alter the results of the examination. In general, the results of this study support the hypothesis that the computer-administered version of the CLEP General Examination in English Composition produces results equivalent to those obtained from the traditional paper-and-pencil version.
