A Curriculum Planning Model for an Intelligent Tutoring System

The previous version of our Intelligent Tutoring System, Circsim-Tutor (CST) had only four procedures with no difference in difficulty level. However, our new version has 83 procedures that are classified into five Content Categories, five Procedure Difficulty Levels and four Procedure Description Levels. This variety requires Curriculum Planning. Sometimes students may know more than the system does about their ability. CST allows students to adjust the difficulty of the next procedure set. The Curriculum Planner determines which procedures to display for student selection on the basis of prior performance and current estimates of the student domain knowledge.
