In response to requests from the University of Alberta Department of Computing Services for PLATO (Programmed Logic for Automatic Teaching Operations) applications in structured learning situations, a program for computer-assisted bibliographic instruction (BI) was developed. The program is divided into the following six units: (1) Introduction; (2) How to Find Books; (3) How to Find Periodicals; (4) Research Strategy; (5) Simulation 1, a hypothetical English assignment; and (6) Simulation 2, a hypothetical political science term paper assignment. Quizzes administered after the second and third units require a grade of 75% or better to proceed, and scores are assigned to performance on the simulations. To test the program, an experiment was conducted in which half the students in each English 200, 210, and 215 class viewed the PLATO program and half received traditional BI. Control group students completed questionnaires containing questions identical to those answered by the experimental group in response to the quizzes and simulation exercises. Results for the experimental group showed that these students selected many more correct answers than incorrect answers, indicating that PLATO can effectively and efficiently teach elementary and essential library skills, and that, although it has limitations, it can effectively be integrated into a comprehensive BI program. Results for the control group are not reported here. (KM)
