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 National Science Foundation. 

For instructors:  For researchers:  We use Andes to investigate how students learn physics and how to improve intelligent tutor systems.

Andes was developed at the Arizona State University and the University of Pittsburgh with support from the Pittsburgh Science of Learning Center, National Science Foundation award No. SBE-0836012, and the Office of Naval Research, grant No. N00014-96-1-0260.
