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.

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.
