Abstract

This paper discusses three extensions to a geometry coach The student model has been enhanced to make it interactive either the student or the modeller can initiate exchanges about the state of the students knowledge The modeller also tracks all of the historical changes in the student model by recording the model state every time a change occurs Finally the paper discusses problem solving strategies that the coach uses to approach congruence proofs from many angles These include analogy construction problem decomposition and animation experimentation backward chaining and brainstorming
