In this volume a relatively new approach to writing process research is attempted; time is included as a very important factor in describing the writing process. The link between the writing process of 12-year old students, the quality of the compositions, and writing skills is investigated in six studies, discussing the importance of genre knowledge, linguistic skills, and cognitive skills in writing. Including linguistic and cognitive skills gives new perspectives on the relationship between the writing process and the resulting composition. The concepts used in these studies are drawn from the fields of both linguistics and cognitive psychology.
