Mathematics intelligent tutoring system for learning multiplication and division of fractions based on diagnostic teaching

This paper develops and evaluates a dialogue-based mathematics intelligent tutoring system (ITS) for teaching multiplication and division of fractions to sixth graders, using diagnostic teaching methods to identify student misconceptions in real-time and provide adaptive instruction. A quasi-experimental study with 66 students showed the ITS significantly outperformed conventional classroom instruction, particularly for lower-performing students.

A one-on-one dialogue-based mathematics intelligent tutoring system (ITS) for learning multiplication and division of fractions was developed and evaluated in this study. This system could identify students’ error types and misconceptions in real-time by using a block-based matching method. The adaptive dialogue-based instruction was supported by a response-driven tutoring model, which was constructed based on the diagnostic teaching methodology. Instructional strategies including provoking cogn
