Individualized Learning System Chemistry (ILS Chem) is a multi-media approach to learning basic chemical principles and their application to man's daily existence in which the student proceeds at his own rate through a series of instructional loops. This is a computer-managed, competency-based instructional system in which the individual student is assigned learning experiences on the basis of his performance. This sequence of instructional loops, primary, remedial, and enrichment, may contain readings, audio or video tapes, field experiences, journal references, films or film loops, conferences, or computer-assisted instruction modules. The computer system also permits the random generation of comparable, criterion-referenced examinations and their scoring. The results of using this approach in Introductory Chemistry at West Chester State College during the past two years showed that the ILS Chemistry students consistently demonstrated a more favorable attitude toward both chemistry in general and their particular class than did the traditional chemistry students. There also exists evidence to suggest that ILS Chemistry students learned more chemistry than did their traditional counterparts in one evaluation and produced cognitive results at least as good as the traditional classroom in another evaluation.
