Engaging undergraduate students in internalizing motivation theories is challenging. They live the concepts but have trouble applying their experiences to understanding the dynamics of motivation theories or deriving practical value from applying the theories to case analysis. We have adapted a human-centered design tool for an exercise that facilities personalizing an experience and then applying motivation concepts. We titled it delight/frustration letter and have used the activity in 17 sections of organizational behavior and leadership courses. The affective nature of the letters helps students understand the dynamics of motivation theories and the impact of motivation on attitudes, actions, and engagement.
