This study explores integrating Augmented Intelligence (AuI) into an Intelligent Tutoring System (ITS) to address challenges in AI in Education (AIED)—teacher engagement, AI trustworthiness, and resource accessibility. The researchers present MathAIde, an ITS that uses computer vision and AI to grade and provide feedback on student math practice questions using images. MathAIde was designed through a collaborative process that included brainstorming with teachers, high-fidelity prototyping, A/B testing, and real-world case studies. The findings highlight the importance of a teacher-centered, user-centered approach, where teachers retain decision-making power while the AI suggests solutions. The findings demonstrate efficiency, ease of use, and adoptability, particularly in resource-constrained settings. This study advances AIED research by providing practical insights into ITS design that balances user needs with technical feasibility and demonstrating the effectiveness of a mixed-methodology, user-centered approach to implementing AuI in educational technology.
