The Andes Physics Tutor

Andes is an intelligent homework helper for physics.  That is, it replaces the pencil and paper that students would ordinarily use to solve physics homework problems.  Students draw diagrams, enter equations and define variables with the same freedom that they have when using paper.  Yet, unlike a piece of paper, Andes tells students whether their entry is correct by turning it red or green, and Andes will give principle-based hints when asked.  Several semester-long evaluations of Andes showed that students who did their homework on it learned significantly more than students who did the same homework problems on paper. 

Andes is intended for use in an Introductory College Physics course, a high school physics course, or a distance learning course.  It includes over 500 problems that cover most topics in a standard two-semester trigonometry-based physics course.  It is free, courtesy of funding from the Cognitive Science Program of the Office of Naval Research and the National Science Foundation.  Andes was developed at the University of Pittsburgh and the United States Naval Academy.

For instructors:  For researchers:  We use Andes to investigate how students learn physics and how to improve intelligent tutor systems. For the 2008 OLI Workshop:  Questionnaire responses (xls) for Short version of USNA survey & essay questions suggested by S. Gershman.
