This document discusses theories of self-directed learning. It defines self-directed learning as when individuals take initiative to diagnose their own learning needs, formulate goals, identify resources, implement strategies, and evaluate outcomes. Three key aspects discussed are: 1) Tough's learning contracts which help structure self-directed learning. 2) Grow's stages of learner autonomy which range from dependent to self-directed based on student needs and teacher role. 3) Pratt's model of readiness to learn which considers a learner's need for direction and support in determining their stage of autonomy. The document poses questions about factors that influence self-directed learning and how readiness may change based on life stage and situation.
