=== Cognitive model ===

A ''cognitive model'' replicates the domain knowledge and skills comparable to that of a human expert or an advanced student of the domain. A [[cognitive model]] enables intelligent tutoring systems to respond to problem-solving situations in a way similar to a human tutor.<ref>{{cite book|author=Corbett, A.T.|author2=Koedinger, K.R.|author3=Anderson, J.R.|year=1997|chapter=Intelligent Tutoring Systems|editor1=Helander, T.K.|editor2=Landauer, P.|title=Handbook of Human-Computer Interaction|publisher=Elsevier Science|location=Amsterdam}}</ref> A tutoring system adopting a cognitive model is called a cognitive tutor.

A cognitive model is an expert system that generates a multitude of solutions to the problems presented to students. The cognitive model is used to trace each student's solution through complex alternative solution paths, enabling the tutor to provide step-by-step feedback and advice, and to maintain a targeted model of the student's knowledge based on student performance.<ref>{{cite journal|author=Corbett, A.|author2=Kauffman, L.|author3=MacLaren, B.|author4=Wagner, A.|author5=Jones, E.|year=2010|title=A Cognitive Tutor for genetics problem solving: Learning gains and student modeling|journal=Journal of Educational Computing Research|volume=42|issue=2|pages=219–239|url=https://www.cs.cmu.edu/~genetics/Research/2010JEdCompRes.pdf|doi=10.2190/EC.42.2.e|s2cid=62695743}}</ref>
