This paper identifies evidence that significant procedural learning can emerge from process approaches to teaching writing, including from the transition of pupils' writing from draft to revision. It shows how writing schemes that use an underlying process framework to structure learning, give pupils ownership of their own writing and exploit the resources of classes as learning communities can enable pupils to learn how to write more effectively, and in some cases to discover what they want to say through the process of composition. The paper draws on this and other work to set out a number of implications for teaching and classroom practice.
