In a word, learning is decontextualized. We break ideas down into tiny pieces that bear no relation to the whole. We give students a brick of information, followed by another brick, followed by another brick, until they are graduated, at which point we assume they have a house. What they have is a pile of bricks, and they don't have it for long.
