Effects of a two‐generation preschool programme on receptive language skill in low‐income Canadian children
Bibliographic record
Abstract
We evaluated the effectiveness of a two‐generation preschool programme (centre‐based early childhood education, parenting education and family support) on receptive language skills in children living in culturally diverse families with low income. Using a with‐in subject pre‐test/post‐test design, children (N = 112) showed a statistically significant improvement in receptive language skill as measured by the Peabody Picture Vocabulary Test, Third Edition. At post‐test, the children continued to score below typically developing children of the same age. There were no statistically significant differences on receptive language skill with regard to child gender, culture, caregiver education, nor involvement in child welfare services. Only for children of Aboriginal ancestry (n = 40) was the amount of time spent in the programme significantly correlated with the amount of positive change in receptive language skill. When designing early intervention programmes for families with low income, targeting the specific needs of cultural sub‐groups may improve outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
