Declarative and procedural knowledge

Declarative knowledge is knowing facts – ‘what’.

Procedural knowledge is knowing processes – ‘how’.

Most learning requires a combination of the two: what do to, and how to do it.

The distinction is important for learning, because research has shown that for declarative knowledge, we learn best through small amounts of practice spaced over time, whereas for procedural knowledge we need more extensive and experiential practice in order to develop automaticity.
