The study explores the e-learning system of the Computer-Based Agricultural Extension Program (CBAES) and examines the differences in user satisfaction and preferences between the two systems for Agricultural Education and Extension at the Rural Development Administration (RDA) in Korea. It also describes the architecture, services, user interface, preference, and satisfaction for the CBAES. Results show significant differences in terms of "relationship with manager" category and number of CBAES users. This suggests that adults prefer interactive learning rather than reading technical information. (Contains 4 figures and 7 tables.)
