For an instructor, it is important to understand the learning process their students go through as they develop their technique and learn new skills.
Fitts and Posner (Human Performance 1967) developed a theory that suggests a three phases process, and at each phase the student will have different needs from the instructor.
No one can go from not being able to do something directly to being able to do it. All people need to pass through these phases of learning: cognitive, associative and autonomous.
