The Apprentice Tutor Builder (ATB) is a platform that simplifies the creation and personalization of intelligent tutoring systems, empowering teachers to build tutor interfaces and author expert models without specialized programming knowledge.
초록
The Apprentice Tutor Builder (ATB) is a platform designed to simplify the creation and customization of intelligent tutoring systems (ITSs). The key components of ATB are:
Tutor Builder:
- Allows users to design tutor interfaces using a drag-and-drop, row-column layout approach.
- Provides flexibility for users to create diverse and stylistically varied interfaces.
Apprentice Agent Training:
- Enables users to interactively train the underlying AI agent of the tutor.
- Users can provide demonstrations, feedback, and labels to teach the agent how to solve problems.
- The agent learns via a Hierarchical Task Network (HTN) representation and updates its knowledge based on user interactions.
The authors conducted a user study with 14 instructors to evaluate the usability of ATB. Key findings:
- The row-column layout approach to the interface builder was usable by teachers without specialized training.
- The interactive approach to authoring expert models via demonstrations, feedback, and labels was effective.
- Teachers saw value in the potential of ATB and expressed willingness to engage in tutor creation and customization.
- Participants desired additional features for more flexible interface design and better guidance on when the agent has sufficiently learned a task.
The study demonstrates the potential of interactive AI-based authoring tools to empower teachers to create and personalize intelligent tutors for their classrooms.
