The Michigan State University protocol materials on learning were field-tested at the University of South Florida (U.S.F.). The field-testing at U.S.F. did not occur under controlled, experimental conditions. The information needs of the protocol developers were balanced with the instructional obligations of the instructors and the educational needs of the students in the classes. Instructional management problems and error sources were highlighted. Error sources included operant learning, positive reinforcement, negative reinforcement, shaping, respondent learning, and model learning. (Appendixes of field-test material are included.) (MJM)
