Externalizing student models is not a new idea. Particularly, the act of opening up an adaptable student model to learners, peers, and mentors has been given much attention in the past. Nevertheless, externalizing numerical uncertainty handling models that use complex mathematical concepts like Bayesian Networks is considered challenging. In contrast, explaining a fuzzy model, as the variables resemble real world entities, is easier and does not need complex additional visualization systems. This paper describes on-going research regarding opening up a fuzzy logic based student model and the underlying instructional strategies used in a CBL system that uses scaffolding techniques for mentoring.
