Replication research in L2 listening comprehension: A conceptual replication of Graham & Macaro (2008) and an approximate replication of Vandergrift & Tafaghodtari (2010) and Brett (1997)
Bibliographic record
Abstract
Most recent publications related to listening comprehension research deal with listening strategy instruction, metacognitive instruction or multimedia applications. This paper discusses one study from each of these three domains – Graham & Macaro (2008), Vandergrift & Tafaghodtari (2010) and Brett (1997) – and presents the need and possibilities for replication, along with a few minor, but interesting, variations that could help test the robustness of the original study. After providing some background to each of the three domains, we overview the respective studies and propose approaches to replication (both approximate and conceptual) along with the accompanying benefits.

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.
