Teacher formative assessment and talk in classroom contexts: assessment as discourse and assessment of discourse
Bibliographic record
Abstract
There is now widely recognized support for classroom-based formative teacher assessment of student performance as a pedagogically desirable approach to assessment which is capable of promoting learning. However, the highly localized and socially co-constructed nature of this type of assessment has raised conceptual and research issues that transcend the theoretical and epistemological concerns of the more established standardized language assessment. One such issue concerns the part played by classroom spoken discourse in the teaching-assessment interaction between teachers and students. This article argues that there is a need to develop theoretically informed research approaches to study how this type of assessment is accomplished through teacher-student discourse in the classroom. Using data collected in two multiethnic and multilingual elementary classrooms we present an analysis, drawing on systemic functional linguistics, to suggest an approach to empirical research and to discuss a number of teaching-learning and research methodological issues.

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.
