Albert Corbett

Also known as Albert T. Corbett, Albert Thomas Corbett

Albert Corbett is an associate research professor emeritus at Carnegie Mellon's Human-Computer Interaction Institute whose work includes AI tutors for programming, mathematics and genetics. After studying psychology at Brown and Oregon, he joined Carnegie Mellon in 1983 and coauthored the 1995 paper that introduced Bayesian knowledge tracing, a method for estimating which skills a student has mastered. In 1998, he co-founded Carnegie Learning, which developed mathematics courses using Cognitive Tutor technology. His later work included a 2009–2013 genetics tutor project and the 2012 Knowledge-Learning-Instruction framework, which linked knowledge, learning and instruction.

Timeline

  1. 1972–1977

    Psychology at Brown and Oregon

    He earns an AB in psychology with honors at Brown University in 1972 and an MA in experimental psychology at the University of Oregon in 1975. In 1977, he completes a PhD in experimental psychology at Oregon with Wayne Wickelgren as his thesis advisor.

  2. 1977–1993

    Psychology posts and Carnegie Mellon

    He works as a research associate in the University of Oregon's Psychology Department from 1977 to 1979 and as an assistant professor in the University of South Carolina's Psychology Department from 1979 to 1984. At Carnegie Mellon, he serves as a Sloan Fellow in Cognitive Science in the Psychology Department from 1983 to 1985 and as a research associate from 1985 to 1993. In 1993, he joins the Human-Computer Interaction Institute as a research computer scientist.

  3. 1995

    Bayesian knowledge tracing

    In 1995, he coauthors "Knowledge tracing" with John R. Anderson. Their Bayesian knowledge tracing method estimates whether a student has mastered individual skills from correct and incorrect answers.

  4. 1998

    Co-founding Carnegie Learning

    In 1998, he co-founds Carnegie Learning with Carnegie Mellon University and HCII colleagues John Anderson, Ken Koedinger and Vincent Aleven. The company develops and publishes mathematics courses built around Cognitive Tutor technology developed at Carnegie Mellon.

  5. 2000

    Programming tutors and Newell Medal

    In 2000, he publishes work on the ACT Programming Tutor, which uses a model of programming knowledge to follow students' solutions and choose practice problems. He receives an Allen Newell Medal for Research Excellence from Carnegie Mellon's School of Computer Science in 2000.

  6. 2009–2013

    A genetics cognitive tutor

    In 2009, he is principal investigator for a Carnegie Mellon project to develop a genetics tutor that combines conceptual learning with problem solving. The project runs from July 2009 to August 2013 with support from the Institute of Education Sciences.

  7. 2012

    The Knowledge-Learning-Instruction framework

    In 2012, he coauthors "The Knowledge-Learning-Instruction Framework" with Kenneth R. Koedinger and Charles Perfetti. The framework connects three coordinated taxonomies of knowledge, learning and instruction to help apply cognitive science to education.

  8. As of October 2026

    Emeritus professor at Carnegie Mellon

    As of October 2026, he is an associate research professor emeritus in Carnegie Mellon's Human-Computer Interaction Institute.
