title: Contributions of Morphological Skill to Children's Essay Writing.
abstract: Morphological skills have previously been found to reliably predict reading skill, including word reading, vocabulary, and comprehension. However, less is known about how morphological skills might contribute to writing skill, aside from its well-documented role in the development of spelling. This correlational study examines whether morphological skill, as measured by a sentence generation task tapping both derivational morphology and meta-syntactic skills, predicts performance on a standardized essay writing task for fifth- and eighth-grade U.S. students (N= 233), after controlling for grade level, comprehension, and writing fluency. Multilevel analyses indicated that morphological skill and writing fluency were each uniquely predictive of essay quality, and this finding was consistent regardless of whether accurate spelling was required in the morphological task. Our results suggest that morphological skills play an important role in writing, as has been previously documented in reading and spelling.
