Simulated Student, or Sim St, is a CTAT module that learns cognitive skills from model solutions demonstrated by human problem-solvers.

Using Sim St, an author demonstrates solutions to problems in a domain using a student interface connected to CTAT. The Simulated Student observes those demonstrations and generates a set of Jess production rules that replicate the problem-solving steps demonstrated. These production rules are generalizations of the observed behavior. If these generalizations are correct—i.e., are correct implementations of the actual task that is being taught—then they can be added to the cognitive model as correct rules. If the generalizations are incorrect but "plausible" (in the sense that a student might adopt the incorrect conception), then they can be added to the cognitive model as buggy rules. Both correct and buggy rules would form the cognitive model of a Cognitive Tutor, allowing the tutor to perform its usual functions, namely, model tracing and scaffolding.

Access to Simulated Student functions can be found on the CTAT menu Sim. St.
