CIRCSlM-Tutor Version 3 includes a reactive planner, APE - the Atlas Planning Engine. By using this planner, we are able to effectively respond to dynamic changes in the environment of tutoring students to solve problems in cardiovascular physiology dealing with the regulation of blood pressure. Use of the reactive planner allows us to adapt to student initiatives or unpredictable answers to questions by replacing the planner’s responses with newly computed better reactions and allows us to specify new goals to the ITS and have it alter its reaction so as to achieve these new goals. The result is a more cohesive dialog with the student.
