Effects of different teaching methods on the production of Mandarin tone 3 by English speaking learners
Bibliographic record
Abstract
This study compared the effectiveness of two teaching methods on the production of Mandarin Tone 3 by English-speaking students. The control group (n=12) received pitch direction-focused instruction in which Tone 3 was introduced as a falling-rising contour tone while the experimental group (n=12) received pitch height-focused instruction in which Tone 3 was introduced as a low level tone. The ability to produce this tone in monosyllabic words, disyllabic words and sentences was assessed after 1 month, 2 months, and 3 months of instruction. The results showed that the pitch height-focused teaching method improved Tone 3 production in connected tonal environments at the sentence level, whereas the pitch direction-focused teaching method was more effective in training students to produce this tone in isolation. More importantly, unlike the pitch direction-focused method, the effectiveness of the pitch height-focused teaching method generalized to new words. It helped L2 learners to develop a self-learning skill for pronouncing unfamiliar words.

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.
