Comparing Alternative Computer-Based Methods for Preventing Job Task Instructions
Abstract
This study compared the effects of previous task training/experience and alternative methods for presenting procedural instructions on job task performance. Six computer-based methods were examined by having oscilloscope operators perform four equipment-related tasks. The presentation methods were text-only, audio-only, text-audio, text-graphics, audio-training and experience in operating oscilloscopes, the most efficient and effective task performances were obtained through a combination of audio and graphic presentations, an effect which can be further enhanced by the addition of redundant textual instructions. The practical applications and theoretical implications of these findings are discussed. Keywords: Job performance aids, Computer-based communications, Audiovisual presentation methods, Computer aided instruction, Computer graphics.
