A Study of a Direct Interface of the Novice User To a Complex Batch Processed Computer Application.
Link, Albert D.
A research study investigated the validity of directly interfacing an uninitiated user with a complex, computerized batch processing system via a conversational, interactive language. A control group conducted mediated searches of the Educational Resources Information Center's (ERIC) files by consulting with an information specialist. Members of the experimental group directly conducted their own searches, after undergoing training with the ERIC/QUERY Interface Program (EQUIP), a computer-assisted instructional training package. Results showed that: 1) the choice of interface methodology (mediated or direct) did not influence the user's satisfaction with the search; 2) there was no relation between the user's knowledge of the system and his satisfaction with it; 3) those trained by EQUIP showed significant increases in their ability to conduct computer searches of ERIC; and 4) there was no predictive relationship between the user's knowledge of the system and the precision of the resulting search, thus indicating that the system was less than ideal.
