Syntactic Complexity Measures and their Relationship to L2 Proficiency: A Research Synthesis of College-level L2 Writing
Abstract
In this study I evaluate the cumulative evidence on the use of syntactic complexity measures as indices of college‐level L2 writers' overall proficiency in the target language. Based on a synthesis of twenty‐five studies, I arrive at several substantive findings. First, I conclude that the relationship between L2 proficiency and L2 writing syntactic complexity varied systematically across studies depending on whether a second or a foreign language learning context was investigated and whether proficiency was defined by programme level or by holistic rating. Second, aggregating available cross‐sectional findings, I propose critical magnitudes for between‐proficiency differences in syntactic complexity for four measures. Finally, I interpret the limited longitudinal evidence to suggest that an observation period of roughly a year of college‐level instruction is probably needed for substantial changes in the syntactic complexity of L2 writing to be observed. I conclude the paper by discussing implications of these findings for future primary research.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
