Student motivation is an essential component of all educational and learning processes. Without motivation, students lack cognitive presence resulting in little, if any, learning. In the traditional classroom setting, it's up to the teacher to facilitate and maintain student motivation. In an e-learning course however, there is less teacher or facilitator presence and the learner is left alone to interact with the instruction mostly alone. E-learning designers and developers must integrate appropriate motivational elements to ensure the learner sustains his/her motivation throughout the entire instruction to maximize the learning outcome. Over the past few years the Norwegian Armed Forces (NoAF) has incorporated motivational design elements focused on promoting and sustaining motivation into our e-learning courses based on John Keller's ARCS Model of Motivational Design. This paper outlines the rationale, methodology, and resulting implementation.
