This report describes research to develop an intelligent tutor for basic algebra. The initial research objective was to develop a one-to-one computer tutor that would help students understand algebra, and such a tutor for solving linear equations was developed in the early stages of the study. However, it became apparent that any one tutor was too limited, both for the purposes of the study and for those of students. Therefore the emphasis was shifted to developing a generic tutor from which many tutor versions could be constructed. This report documents the rationale for redirecting the research effort, the development of the generic tutor, the development of tutor versions from that generic model, and efforts to evaluate the tutor versions.
