this paper, we examine the components of dynamic skill acquisition using a data set collected by Ackerman (1988) with the Kanfer-Ackerman Air-Traffic Controller Task©. Our analysis indicates that subjects arc improving in both the strategies they use to solve the task and the speed with which they execute the task. One strategy that subjects develop reduces the number of oven actions required lo land a plane. Another strategy that subjects develop enables them to land more planes simultaneously. A satisfactory model of this task must include both an improved strategic component and an improved speed component. The ACT-R theory (Anderson, 1993) is well suited to model these components as it is able lo separately learn over trials which strategies are better and how to execute each more efficiently.
