A comparison of the comprehension of procedural information using computer and hard-copy media
Users of technical procedures must be able to understand the documents to use them to perform their work. As more companies contemplate putting their procedures on-line, it is important to know whether computer systems will be as effective as traditional hard-copy presentation in communicating procedures to the employees who must use them; To determine whether there is a relationship between computer usage and the comprehension of technical procedures, an experiment was conducted among employees of a scientific and technical company in Las Vegas, Nevada. A control group read and demonstrated its comprehension of hard-copy procedures only, while an experimental group read and demonstrated its comprehension of a hard-copy and then an on-line procedure; The experimental group selected fewer correct answers on a comprehension test for the on-line than for the hard-copy procedure. This suggests that when readers accustomed to the hard-copy medium switch to the computer medium, comprehension decreases.
