Efficacy of delivery methods can be compared by studying human memory emphasizing how information is processed. The aim of this research is to identify factors which are influenced by methods of complex e-learning course delivery. Compilation of cognitive load theory and learning ability of Moodle survey plugin aids in analyzing evidence. Two plug-ins -browser extensions which, in this case, were used to monitor user usage -called COLLES (constructivist on-line learning environment survey) and ATTLS (attitudes toward thinking learning survey) were instrumental in measuring user perceptions. Both surveys aided stakeholders (students, instructors, and system managers) in measuring human interaction in order to identify optimal methods. Results suggest that interactivity and connected-knowing approaches are factors that influenced optimal design for complex e-learning course delivery in an Indonesia environment. Our research also opens possibilities towards future research on the influence of gender on learning.
