Title: A LEARNING MODEL OF INFORMATION SYSTEMS: THE EFFECTS OF ORIENTING MATERIALS, ABILITY, EXPECTATIONS, AND EXPERIENCE ON PERFORMANCE, USAGE, AND ATTITUDES

Abstract: Novice users of computer-based information systems are often forced to learn technical information without a clear understanding of each step in using the system. Based on the literature of MIS and Psychology, a model of user understanding was proposed. Inputs to this construct include a user's schematic knowledge structure, experience, job affect, and affective system expectations. Dependent variables include performance, later usage, job affect, and system affect; each is hypothesized to be enhanced when a learner develops a proper cognitive structure before specific, technical training.

A research site was identified with formal initial training in an unfamiliar administrative information system. In early 1984, 91 clerical subjects attended 6 electronic mail lectures. Experimental subjects received a brief, non-technical pre-training organizer; control subjects did not. Ability, experience, and affective measurements were taken during the initial main session. Post-training performance and post-usage questionnaire responses were matched to the initial measurements for hypothesis testing.

Analysis of variance and covariance supported only the performance hypothesis. The usage hypothesis could not be supported because too few subjects used the system after the training, due to strong external factors. The affective hypotheses were not supported because other factors were probably much more important than the cognitive organizer, including a strong degradation of attitudes toward the system. The performance effect is still evident whether the organizer is administered 3 or 19 hours before the performance measures, and when experience or ability covariates are considered.

Studies which concentrate on affective measures alone may not yield significant results, since other factors have stronger impacts on attitudes. Future research should concentrate on replicating the study in more favorable situations; developing better metrics for measuring a user's experience, ability, and affect; and investigating the process, rather than just the outcomes, of subsumption.
