Writing development is currently the focus of substantial international debate because it is the aspect of literacy education that has been least responsive to central government and state reforms. Teaching approaches in writing have been slower to change than those in teaching reading and pupil attainment in writing has increased at a much more modest rate than pupil attainment in reading. This handbook critically examines research and theoretical issues that impact on writing development from the early years through to adulthood. It provides those researching or teaching literacy with one of the most academically authoritative and comprehensive works in the field. With expert contributors from across the world, the book represents a detailed and valuable overview of a complex area of study.
