CONTROLLING CHALLENGE IN INSTRUCTIONAL SIMULATION

This experiment was designed to assess the effects of instructional control mechanisms that altered the degree of challenge in an instructional simulation. Subjects were taught to place an icon at a position and orientation that corresponded to digital and analogue information displayed on a simulated aviation instrument. Three treatments were compared: a) learner control enabled subjects to control challenge; b) learner control with advisement provided the same control accompanied by ongoing advice on control decisions; and c) computer control automatically adjusted challenge. Treatments differentially affected subjects' response time on immediate and delayed tests and their control decisions during practice. Interference of control decisions with acquisition of the criterion skill and subjects' perceptions of their performance are discussed as potential contributors to the effects of the treatments.
