“There are two dimensions to the learning process: grasping and transforming experience. We grasp experience by feeling/doing (concrete experience) and by thinking/theorizing (abstract conceptualization). We transform experience by watching/reflecting (observation/reflection) and by doing/applying (active experimentation).”
