Engagement in Playground Activities as a Criterion for Diagnosing Developmental Coordination Disorder
Bibliographic record
Abstract
The purpose was to develop a valid protocol for use by physical educators in assessing whether children suspected of having developmental coordination disorder (DCD) meet the American Psychiatric Association (1994) diagnostic criterion of interference in activities of daily living when interference is defined as culturally subaverage engagement in activities of daily living in physical play (ADL-PP) on the playground. Participants were 136 children (75 girls, 61 boys) from Grades 1 to 4 at three elementary schools in Canada. Data were collected two ways: (a) three administrations of an ADL-PP self-report of activities done during recess and (b) observation of children’s ADL-PP during two recess periods. Examination of reactivity, accuracy, content relevance, and content representativeness of the ADL-PP report form indicated protocol validity. An example illustrating the use of the ADL-PP self-report protocol to identify interference is described.

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.
