EDUM is a learn to earn (S2E) program that rewards students for learning in the X2E model. It is the world's first learning behavior-based program that measures/certifies learners' learning activities and provides appropriate rewards (earned). EDUM S2E follows a process that includes goal setting, self-directed learning, goal achievement, and learning rewards, allowing learners to earn rewards through this process. This series of steps is provided to learners through EDUM's S2E service tools and the educational services of partner companies, and plays a core role in building EDUM's innovative education ecosystem.
