概要 Mastering a skilled motion usually requires a step-by-step progression through multiple learning phases with different subgoals. It is not easy for a learner to properly organize such a complex learning process without assistance. Hence, this task is often facilitated interactively by a human instructor through verbal advice. In many cases, the instructor’s teaching strategy in relation to decomposing the entire learning process into phases, setting a subgoal for each learning phase, choosing verbal advice to guide the learner toward this subgoal, etc. remains intuitive and has not yet been formally understood. Thus, taking the basic motion of wok handling as an example, this paper presents several concrete teaching processes involving an advice sequence and the corresponding changes in the motion performance in a feature variable space. Thereby, the paper analyzes and represents the actual strategy taken in an easy-to-interpret form. As a result, it confirms that the instructor determines the set of advice elements to be given based, not simply on the observable characteristics of the latest motion performance, but more adaptively upon the interaction history with the learner.
