"A great update of a classic. Should be required reading for anyone involved with adult learning in schools, businesses and communities". (Sam Stern, Professor & Dean, School of Education, Oregon State University, USA). How do you tailor education to the learning needs of adults? Do they learn differently from children? How does their life experience inform their learning processes? These were the questions at the heart of Malcolm Knowles' pioneering theory of andragogy which transformed education theory in the 1970s. The resulting principles of a self-directed, experiential, problem-centred approach to learning have been hugely influential and are still the basis of the learning practices we use today. Understanding these principles is the cornerstone of increasing motivation and enabling adult learners to achieve. This update of a pioneering classic contains all Knowles' original chapters alongside a newer second part by Elwood 'Ed' Holton and Richard A. Swanson charting the advancements on these core principles.A third section includes selected readings from previous editions to illustrate the theory's evolution, as well as important articles from other key experts around the world for a comprehensive view.
