Andes is an intelligent problem-solving tutor for classical physics.  It was used in the fall semester of 1999 and 2000 by a group of approximately 150 students.  An assessment of its effectiveness was made using: 1) comparative results on a free-response test taken by the Andes group and a control group, 2) portfolios of the students' work and 3) student opinion surveys.  The results of the assessment highlight some strengths and weaknesses of Andes.
