UR, S. & VanLehn, K. (1994). STEPS: A preliminary model of learning from a tutor. In K. Eiselt & A. Ram (Eds.) Proceedings of the Sixteenth Annual Conference of the Cognitive Science Society, 893-898. Hillsdale, NJ: Earlbaum.

This paper describes a prototype of a simulaled physics student that learns by interacting with a human tutor. The system solves physics problems while showing its work on a work· station screen, and the tutor can intervene at certain points during problem-solving to advise the simulaled student. This prototype constitutes an initial cognitive task analysis of the skill of learning from a tutor, which prescribes several tutoring practices that appear to be plausible for both human and computer tutors.
