Abstract
This study examined the relationship between computer-user interface (character based or graphical) and the quality of written documents. Students were randomly assigned to one of two business communication labs, Macintosh or IBM. Both groups received identical lectures on business communication principles and practices. T-test analyses of two documents produced during the course compared the groups on four document criteria: content, structure, mechanics, and format. After six weeks of business communication instruction, including three 50-minute class periods of instruction on their respective computers and software, IBM users excelled on the criteria of mechanics (as hypothesized) and format (contrary to the hypothesis). After an additional five weeks of business communication instruction and use of their respective computer systems, the two groups demonstrated no significant differences on any of the criteria. The findings challenge Halio's claims for the superiority of character-based interface.
