Mathematics intelligent tutoring system for learning multiplication and division of fractions based on diagnostic teaching
This paper develops and evaluates a dialogue-based intelligent tutoring system (ITS) for teaching sixth-grade students multiplication and division of fractions, using diagnostic teaching methodology with real-time error identification and adaptive instructional strategies. The system was tested through a quasi-experimental study with 66 sixth graders, showing significant learning gains compared to conventional classroom instruction.
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
