The online module includes the user interface design, the learner interface and the instructional design. This chapter would examine the theories behind these three designs. What guidelines can be garnered from the theories of these three designs? How can these guidelines be used to develop a user-friendly online module? In addition, it would examine their similarities and how they can be used to develop a user-friendly online module. Further, the chapter recommended an alignment of the garnered guidelines from the three designs to explore the plausible reasons for the high attrition rate in Massive Open Online Courses (MOOC).en-USIn CopyrightInstructional designUser interface designLearner interface designUser-FriendlyOnline moduleProcessesInputsOutcomesAffordanceMinimalismMassively Open Online CoursesMOOCsBook chapter
