Analysis of Use of a Micro-Computer Driven Classroom Display. Working Paper #82-30.
Howson, H. R.; Powell, A. J.
The instructional effectiveness of using an IBM personal computer with an Electrohome Character projector and a flat screen to display instructional material was analyzed with 89 students enrolled in a course on management information systems at McGill University. The lesson used was an introduction to VisiCalc, an applications software package, and consisted of a 15-minute introductory lecture followed by a 70-minute presentation, during which time the microcomputer and display projector were used continuously and classroom lighting was dimmed. The display projected was green on black, and a 40-character-per-line mode was used. Following the presentation, students answered a 22-item, multiple choice questionnaire which covered the topics of seating position and classroom environment, perception of the screen display and its usefulness, prior experience with VisiCalc and computers, and knowledge of materials. Classroom environment and screen display were perceived positively. The media were effective for the class size studied, though room lighting and display design were identified as critical variables: concentrated light sources between the subject and the display should be avoided, as well as use of the extreme fringes of the display area. Six references are listed. (LMM)
