Reactive Instructional Planning to Support Interacting Teaching Strategies

We propose an architecture for reactive planning of contents in instruction. It is based on a framework for reactive planning which integrates opportunistic reactions with plan-based (plan-repairs and complete replanning). It is suggested how this framework can implement two radically different teaching styles, tutoring and coaching, as well as their interaction within one system. One additional advantage is the possibility to manage the way of system's reacting by means of different pedagogical rules. At this point the system has been implemented and experimented in the domain of integration of elementary functions.
