Principles of adult learning
– Participatory - adults learn by doing– Self-directed and informal – They do most of their
learning on their own, jumping around to find what is most relevant and interesting.
– Connected to existing knowledge and experience– Practical and goal-oriented - learn what they need
to solve a problem– Convenient – barriers to real progress should be
minimized
“Creativity is a learning process where the teacher and the pupil are located in the same individual”
Arthur KoestlerBritish novelist and essayist
“Creativity in science could be described as the act of putting two and two together to make five”
Arthur Koestler
