Construction of a Classroom ZPD Through “Graduated, Contingent, and Dialogic” Mediation at Three Strata of Classroom Discourse
Bibliographic record
Abstract
The present study adopts an interactional ethnographic approach to trace the establishment of class Zone of Proximal Development (ZPD) through a detailed examination of the distribution of mediational tools/moves, interactional modes, and the changing nature and functions of discursive events within three strata of the classroom space. Observation and coding of 70 hours of classroom footage, an in-depth study of the cadence of one full instructional unit, and microgentic analyses of key discursive events reveal how a teacher framed joint activities that advanced the class ZPD. The findings expand Newman, Griffin, and Cole's (1989) metaphor that described the classroom as ‘a construction zone with multiple concurrent work areas and spaces by documenting how work done in each space and the opportunities for learning created in each act of interaction or collaboration adds to the overall capital of the classroom, shaping the learning potential of the group.

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.
