Abstract
This study examines the effects of teaching common complex grapheme‐to‐phoneme correspondences (GPCs) on reading and reading motivation for at‐risk readers using a randomised control trial design with taught intervention and control conditions. One reading programme taught children complex GPCs ordered by their frequency of occurrence in children's texts (a ‘simplicity principle’). The other reading programme taught children word usage. Thirty‐eight students participated in the 9‐week programme of 30 supplemental small group sessions. Participants in the complex GPC group performed significantly better at post‐tests with generally large value‐added effect sizes (Cohen's d ) at both by‐participant and by‐item for spelling, d = 1.85, d = 1.16; word recognition with words containing taught GPCs, d = 0.96, d = 0.95; word recognition, d = 0.79, d = 0.61, and reading motivation, d = 0.34, d = 0.56. These findings suggest that the simplicity principle aids in structuring maximally effective supplemental phonic interventions.

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 it
