The Linguistic Pathways Model: Capturing the Multiple Dimensions of Reading Development
Bibliographic record
Abstract
ABSTRACT The importance of oral language skills in reading comprehension is widely recognized in contemporary models. Building on this foundation, we propose the Linguistic Pathways Model. In this model, we illuminate mechanistic and developmental detail by which individual components of oral language support reading comprehension and embrace the multiple dimensions across which reading development plays out. This is the level of theoretical detail needed to inform instruction in the classroom that is most likely to propel children on strong trajectories of reading development. We illustrate the value of this model by focusing on syntactic skills—the ability to understand and manipulate sentence structure. We hypothesize two core pathways by which syntactic skills impact reading comprehension. In the syntax‐to‐lexicon pathway, syntactic skills influence how readers construct lexical representations, ultimately impacting reading comprehension. In the syntax‐to‐sentence pathway, syntactic skills affect reading comprehension by shaping how readers parse sentences and generate predictions about upcoming information. In each, we elaborate on mechanisms of these influences. We also detail the nature of developmental effects, including changes in relative reliance on skills over time and the temporal order of effects, and the interactions between the two. This work provides a new theoretical model for understanding the precise pathways through which individual oral language skills contribute to reading comprehension development, making predictions that are testable in classrooms.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
