Knowles describe Self-Directed learning (SDL) in broadest meaning as “a process in which individual take the initiative, with or with out the help of other, to diagnose their learning needs, formulate learning goals, identify resources for learning, select and implement learning strategies, and evaluate learning outcomes” (Knowles, 1975, p.18) while other describe this process as self-planned learning, inquiry method, independent learning, self-education, self-instruction, self-teaching, self-study, and autonomous learning. These labels seem to imply learning in isolation, whereas Knowles pointed that SDL usually takes place in association with various types of helpers. For example, teachers, tutors, mentors, and peers. In addition, there is a lot of mutuality among a group of self-directed learners.
