Abstract
We examined whether a Phonics + Set for Variability (S f V) reading intervention would lead to better irregular word reading compared to Phonics + Morphology within a cluster randomized control trial (RCT) design with a follow-up measurement. The participants were 273 Grades 2 and 3 students with reading difficulties (139 in the Phonics + S f V and 134 in the Phonics + Morphology) who received intervention in small groups (2–4 children), 4 times a week, 30 minutes each time, for 15 weeks. All participants were from schools in Alberta, Canada. Results of hierarchical linear modeling showed that there was a significant effect of intervention on all reading outcomes (e.g., from pre- to posttest the effect sizes for Phonics + S f V ranged from g = 0.74 to 1.54 and for Phonics + Morphology from g = 0.75 to 1.49). Unexpectedly, there were no differences between the intervention conditions in any of the outcome variables, including irregular word reading and morphological awareness that the interventions partly focused on.

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
