It's in the Way That You Use It: How Vocabulary Knowledge and Usage Predict Writing Quality Among Adult Basic Education Learners.

The goal of this study was to describe how underlying vocabulary knowledge manifests into vocabulary usage, and in turn, how usage predicts writing quality among adult basic education (ABE) learners. ABE learners were administered tasks that measured vocabulary knowledge, in the forms of both vocabulary breadth and depth. Participants were also given a composition writing task, and these samples were evaluated for overall writing quality and vocabulary usage.
