Preschool cognitive control and family adversity predict the evolution of classroom engagement in elementary school
Bibliographic record
Abstract
Background: Classroom engagement is key predictor of child academic success.Aim: The objective of the study was to examine how preschool cognitive control and the experience of family adversity predict developmental trajectories of classroom engagement through elementary school.Setting: Children were followed in the context of the Quebec Longitudinal Study of Child Development from birth to age 10.5 (N = 1589).Methods: Working memory was directly assessed when children were 3 years old and mothers reported child impulsivity, parenting characteristics, stress and social support when children were 4 years old. Elementary school teachers rated classroom engagement from kindergarten through Grade 4.Results: Growth mixture modelling identified three distinct trajectories of classroom engagement. Child working memory and impulsivity, and maternal hostility, social support and stress predicted greater odds of belonging to the low versus high engagement trajectory. Child impulsivity and maternal hostility and stress also distinguished between the low and moderate engagement trajectories.Conclusion: Our results suggest that targeting preschool cognitive control and buffering the effects of family adversity on children may facilitate academic success.

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.
