I work with lots of folks who create and deliver some kind of instruction — training, documentation, presentations and such. I’m planning to have this quote from Etienne Wenger tattooed on my forehead in large letters, just so they can think about it.
“Instruction does not cause learning; it creates a context in which learning takes place, as do other contexts. Learning and teaching are not inherently linked. Much learning takes place without teaching, and indeed much teaching takes place without learning.”
