The Linear Programming Intelligent Tutoring System (LP-ITS) was designed and developed in an effort LP-ITS analyzes the student's solution step by step to determine the weak points of the student and intelligently guides the student towards the correct solution of the linear programming problem. LP-ITS is intended to be used by students enrolled in Linear Programming course at the University level. This paper discusses the Human Computer Interaction (HCI) design elements in the LP-ITS for improving the Linear programming Intelligent Tutoring System. LP-ITS has been and is currently being field-tested by students enrolled in Operations Research in the
