This tribute will highlight what may be three of Bijou's most significant contributions to practice, namely his studies on (a) programmed instruction for children with developmental disabilities (Bijou, Birnbrauer, Kidder, & Tague, 1966), (b) children's responding under schedules of reinforcement and extinction (Bijou, 1957), and (c) the use of descriptive analysis to identify functional relations (Bijou, Peterson, & Ault, 1968).
