We teachers - perhaps all human beings - are in the grip of an astonishing delusion.
We think that we can take a picture, a structure, a working model of something, constructed in our minds out of long experience and familiarity, and by turning that model into a string of words, transplant it whole into the mind of someone else.
Perhaps once in a thousand times, when the explanation is extraordinary good, and the listener extraordinary experienced and skillful at turning word strings into non-verbal reality, and when the explainer and listener share in common many of the experiences being talked about, the process may work, and some real meaning may be communicated.
Most of the time, explaining does not increase understanding, and may even lessen it.

I love this quote from John Holt. Knowledge is not best transferred by explanation, but through dialogue.
