Steven Ritter

Steven Ritter is currently the Chief Scientist at Carnegie Learning, Inc., a mathematics publisher based in Pittsburgh, PA. Ritter helped to found the company in 1998.^[1]

Ritter has spent most of his career developing and evaluating educational systems. He earned his Ph.D. in Cognitive Psychology at Carnegie Mellon University in 1992. As a postdoctoral associate and research scientist at Carnegie Mellon, Dr. Ritter was instrumental in the development and evaluation of the Cognitive Tutors for mathematics. He is the author of numerous papers on the design, architecture and evaluation of Intelligent Tutoring Systems and served as chairman of the IEEE Learning Technology Standards Committee working group on tool/agent communication.
