Self-directed learning is a point at which you are responsible for your own learning. It is an important stage to reach for life long learning. Grow’s model suggests that a learner develops through four stages. Stage one: a dependent learner, stage two: an interested learner, stage three: an involved learner, and stage four: a self-directed learner. At each stage the student learns in a different manner. They will have different needs, interests, stimuli. So as an instructor, being able to determine what stage each student is at and change the teaching style accordingly, will make for more efficient learning. Catering to each students needs will keep them more interested and motivated.
