The demand for educational technology has increased research into Intelligent Tutoring Systems (ITS) for low-connectivity regions. However, misalignment between requirement discovery and software development hinders adoption. This case study examines the development of an unplugged ITS using dual-track agile development and participatory design to ensure continuous alignment with pedagogical needs. This study contributes to software engineering by demonstrating how dual-track development and participatory design enhance agility while maintaining a user-centered approach, offering a scalable model for ITS applications in low-resource environments.
