Internally Generated Feedback with an Instructional Expert System.
Grabinger, R. Scott; Pollock, Joellyn
This study evaluated the effectiveness of an expert instructional system used to provide timely and quality feedback about the quality of a variety of visual materials production techniques to undergraduate students in a basic instructional materials production class. One group of students generated its own feedback by using the expert system, and the other group received feedback from a teacher. The expert system used a question and answer approach which required students to relate textual information to what they already knew, and to evaluate each production project based on a set of criteria for that project. The evaluation task was subjected to two measurements: (1) a content analysis, which was used to count the number of standard criteria cited and the number of new criteria applied or generated; and (2) opinion measurements, which included a self-rating of learning and a rating of the expert system. Nether the quality measurement nor the citation of details measurement (except for evaluation of lettering samples) produced significantly higher results for the group using internally generated feedback. However, the internally generated feedback group produced a significantly greater number of non-standard criteria in the second measurement of the evaluation task. Overall, the opinion measurements of the students who used the expert system to generate their own feedback about their project were favorable. The text is supplemented by 2 figures, 5 tables, and 19 references. (EW)
