The document outlines Fitts and Posner's three-stage model of skill acquisition: 1) the cognitive stage, where learners develop a mental representation of the skill through observation and mental rehearsal; 2) the associative stage, where practice links ideas and improves speed, accuracy, and consistency through reduced errors and increased proprioception; and 3) the autonomous stage, where the skill can be performed automatically with little conscious effort, freeing the learner to focus on other strategic aspects.
