ALEX (Active Learning EXperience)

Abstract

Traditional learning management systems are cloud-based and teacher-centric, limiting accessibility, flexibility, and student-centered learning. We present the Active Learning EXperience (ALEX), a decentralized learning management system aligned with Education 4.0, supporting flipped and project-based learning. ALEX leverages Web3 technologies (blockchain, InterPlanetary File System, and offline-first mechanisms) to enhance security, privacy, and access in low-connectivity environments. This study evaluated, through the case study method, ALEX's usability, performance, and pedagogical impact with nine third-year information systems students and one facilitator in an authentic project-based course at a Brazilian university, with two non-governmental organizations taking part as clients. Instruments included a custom usability questionnaire, and a pre/post-test skill assessment. Results showed significant improvements in hard and moderate improvement in soft skills, suggesting further enhancements. Future work will focus on expanding ALEX's collaborative features and scalability testing to strengthen its impact on student engagement and learning outcomes.
