Action Schools! BC implementation: from efficacy to effectiveness to scale-up
Bibliographic record
Abstract
OBJECTIVES: To describe Action Schools! BC (AS! BC) from efficacy to scale-up. PARTICIPANTS/SETTING: Education and health system stakeholders and children in grades 4-6 from elementary schools in British Columbia, Canada. INTERVENTION: At the provincial level, the AS! BC model reflected socioecological theory and a partnership approach to social change. Knowledge translation and exchange were embedded as a foundational element. At the school level, AS! BC is a comprehensive school health-based model providing teachers and schools with training and resources to integrate physical activity (PA) and healthy eating (HE) into the school environment. Our research team partnered with key community and government stakeholders to deliver and evaluate AS! BC over efficacy, effectiveness and implementation trials. RESULTS: On the basis of significant increases in PA, cardiovascular fitness, bone and HE in AS! BC schools during efficacy trials, the BC government supported a provincial scale-up. Since its inception, the AS! BC Support Team and >225 trained regional trainers have delivered 4677 teacher-focused workshops (training approximately 81,000 teachers), reaching approximately 500,000 students. After scale-up, PA delivery was replicated but the magnitude of change appeared less. One (HE) and 4 (PA) years after scale-up, trained AS! BC teachers provided more PA and HE opportunities for students even in the context of supportive provincial policies. CONCLUSIONS: Whole school models like AS! BC can enhance children's PA and health when implemented in partnership with key stakeholders. At the school level, adequately trained and resourced teachers and supportive school policies promoted successful scale-up and sustained implementation. At the provincial level, multisectoral partnerships and embedded knowledge exchange mechanisms influenced the context for action at the provincial and school level, and were core elements of successful implementation.

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.
