STutor

STutor is a tutor program that helps students develop procedural fluency in Stoichiometry problem solving. The program uses an innovative algorithm to chart pathways to solving a wide class of Stoichiometry problems with varying degrees of difficulty STutor has an intuitive user interface that effectively captures the parameters for a given problem. The underlying algorithm elucidates parameters that are not provided but are required for solving the problem. STutor produces a text script containing steps to solving the problem in the learn mode, and is converted into an Intelligent Tutoring System (ITS) in the practice mode
