Intelligent Tutoring System (ITS) is computer software designed to simulate or imitate a human tutor’s behavior and guidance. By having the capability to interpret complex students’ responses and to estimate the students’ degree of mastery, ITS adeptly tailor their tutoring behavior. Despite its intelligent capability, there remains a need for improvement in the ITS concerning performance measurement, predictive accuracy, and adept handling of uncertainty in student interactions. Motivated by these considerations and the recognition that ITS can further enhance their effectiveness in guiding students toward a comprehensive understanding of specific topics, this study introduces a novel mechanism within the student module. The primary objective is to present innovative criteria and approaches for measuring a student’s degree of mastery through meticulous data pre-processing. The study involved pre-processing data files to extract more meaningful information, aligning with its ov.....
