First Published in 1987. Part of a series on the psychology of education and instruction, this volume marks a highpoint in the development on writing from a cognitive perspective. It significantly expands the data base upon which our understanding of writing rests. the book presents an original theory, or at any rate, the beginnings of a theory of writing and the development of writing skills, emphasizing the control processes in writing. "Those who are concerned with promoting general cognitive attainment will find that knowledge-transforming writing is a powerful tool for achieving that end. Scholars with a primary interest either in writing or in cognitive science will find much of interest both in the specific experimental techniques that Bereiter and Scardamalia describe and in the overall conceptual framework of the volume."—Contemporary Psychology
