Mobile Microlearning to Scaffold Project-Based Learning Using ARCS Model: A Preliminary Study

This study reports on the development and implementation of the Interactive Design Research Toolkit (IDRT), a mobile application that supports the teaching and learning (T&L) of Human-Centered Design (HCD) practices. Guided by the Attention, Relevance, Confidence, and Satisfaction (ARCS) Model of Motivational Design and leveraging mobile microlearning (MML) principles, the IDRT integrates multimodal instructions and gamification features to encourage students to employ HCD. Implemented in a design-project-based class, 37 students' perceptions and engagement were evaluated using the Instructional Materials Motivation Survey. Results indicate positive feedback, high engagement levels, and increased comprehension of HCD. Analysis of design reports reveals a more diverse application of HCD, particularly among higher-performing students, indicating the IDRT's influence on intrinsic motivation. However, challenges were identified among lower-performing students, indicating the need for further research to enhance engagement. Overall, the study underscores the potential of MML as a viable instruction method to influence students' motivation and proficiency positively and to scaffold the T&L of HCD.
