Abstract: An important topic in courses in propositional logic is rewriting propositional formulae with standard equivalences. This paper analyses what kind of feedback is offered by the various learning environments for rewriting propositional logic formulae, and discusses how we can provide these kinds of feedback in a learning environment. To give feedback and feed forward, we define solution strategies for several classes of exercises. We offer an extensive description of the knowledge necessary to support solving this kind of propositional logic exercises in a learning environment.

Keywords: domain reasoner, feed forward, feedback, intelligent tutoring, learning environment, normal forms, propositional logic
