Tagging pupils' expository writing: Hunting for emerging background as quality development

In this invited conference presentation I analysed pre and post intervention writings from a case writer within the Norms project who developed markedly. By tagging the texts using discourse functional units and their discourse roles I was able to show a) what development consisted in, b) that the development can be subsumed under the concept of discourse backgrounding and c) that a dialogical understanding is necessary to handle several layers of contextual influences.
