More recently, David Kolb helped to popularize the work of Dewey, Lewin and Piaget, through his cyclical
model stating that experiential learning is a multidimensional process. It begins from concrete experience to
reflective observation, then to abstract conceptualization to active experimentation (Dunlap et al., 2008). In other
words, the first stage is where the learner actively experiences an activity. The second stage is when the learner
consciously reflects back on that experience. The third stage is where the learner attempts to conceptualize a theory
or a model of what is observed. The fourth stage is where the learner is trying to plan how to test a model or theory
or plan for a forthcoming experience.
