Andragogy: The art and science of helping adults learn. This concept, popularized by the educational theorist Malcolm Knowles 1913–1997, emphasizes hands-on task- or problem-centered learning as the most effective method for teaching adults.
An example in medical education might be assigning students to groups in which they would practice intubation procedures using a manikin. Much is made in the literature on andragogy of the idea of harnessing intrinsic motivation. In this case, the students would obviously want to master a crucial skill and would be more likely master to it if given a hands-on opportunity to do so.
As your teacher I want you
To get a chance to really do
Useful things that no doubt will
Endow you with a real skill
