This discussion of the relationship between self-directed learning, adult development, and distance education presents findings from researchers in the field of autonomous learning. In addition, the implications of self-directed learning for the curriculum and teaching methods in distance education are considered. The document is divided into the following sections: (1) assumptions about learning and teaching; (2) the self-directed or autonomous learner; (3) topics in which self-directed learners are interested; (4) the implications of self-directed learning for the organization of distance education systems; (5) teaching the self-directed learner; (6) the author's personal experience with an open university course for adults, "Education for Adults"; (7) technology in the service of the individual; (8) a chart summarizing the life cycle research theories of eight contemporary researchers; (9) a section of the course outline for "Education for Adults"; and (10) a list of references.
