Growth in Grammar

Growth in Grammar was a three-year project studying how English children’s written language develops as they progress through their school careers. 

We hope that this research will provide new understandings of writing development that will inform teaching and curriculum design.

The Growth in Grammar project aimed to further our understanding of how the language of children’s writing develops as they progress through the education system in England, from ages six to sixteen.

We collected 2,898 texts from 983 children in 24 schools and used a number of computer-assisted methods to understand differences in the use of grammar and vocabulary across year groups and text types. For a brief overview of the corpus, see here.
