Three methods of sequencing coordinate concepts (simultaneous, collective, and successive) were investigated with a Bayesian, computer-based, adaptive control system. The data analysis showed that when coordinate concepts are taught simultaneously (contextually similar concepts presented at the same time), student performance is superior to either…

Senior high students who were given concepts simultaneously learned more than those who received concepts successively. A second variable, instructional control strategy, contrasted an adaptive (computer-assisted) control strategy with learner control. Performance was above the criterion level for the adaptive condition, but below it for learner…
