This document discusses self-directed learning. It defines self-directed learning as any learning that an individual initiates and controls through their own efforts, using various methods at any time. The key principles of self-directed learning are that it should be lifelong, natural, individualized, and involve all human capabilities. The process involves diagnosing learning needs, setting objectives, finding resources, implementing strategies, and evaluating outcomes. Teachers play a role in teaching skills like inquiry and decision making, helping learners develop independence and self-evaluation skills, and creating a supportive learning environment.
