The Department of National Defense in South Korea is taking steps to develop smart learning to prepare for the information age, but as of yet there have not been any sufficient empirical analyses on learning satisfaction. The findings of this study showed the following factors as positively affecting learning satisfaction with e-learning in the military: learning motivation, ease of the use environment, learning support level of the organization, content feasibility, and instructor-learner interaction. Similarly with the official education centers and universities, learning motivation was proven to be the most important factor in e-learning education in the military. Also, as factors that reflect the nature of the military, ease of the use environment and learning support level of the organization were identified as factors that affect learning satisfaction. This result suggests the importance of the infrastructure and setting for e-learning in the military. The factors of content feasibility and infrastructure-learner interaction were also shown to affect learning satisfaction. Suggesting further investment in the design and development of e-learning contents and an increased proactiveness of the instructors to improve learning satisfaction.
