A Comparison of the Usability of Notebook and Desktop Computers at the United States Air Force Academy

Abstract

Abstract : The purpose of this study was to assess the effect of portable computers on the USAFA faculty's ability to contribute to teaching, research, and service. The objectives of the study were to determine (1) the criteria under which notebook computers were feasible alternatives to desktop computers; (2) which features of notebook and desktop computers faculty used; (3) which software products faculty used on notebook and desktop computers; (4) the criteria under which a similar investigation should be conducted with cadets; and (5) a research basis to facilitate the identification of potential applications of notebook computers for the Air Force and Department of Defense. The sample consisted of 93 faculty members (experimental n = 54, control n = 39). Faculty members in the experimental group turned in their desktop computers for notebook computers. Faculty in the control group received new desktop computers, changing their operating system simultaneously. The groups were found to be demographically similar. A series of five surveys were used to collect data over the eleven-month period of the study. The initial survey provided baseline data; three periodic surveys and an exit survey tracked the faculty through the course of the study; and the exit survey provided additional data as the study came to a close. Both quantitative and qualitative data were collected and analyzed. Major findings of the study are reported by computer type.
