Abstract
Abstract The present meta‐analysis aimed to summarize the extent to which second language vocabulary is learned from the most frequently researched word‐focused activities: flashcards, word lists, writing, and fill‐in‐the‐blanks. One hundred effect sizes from 22 studies were included in meta‐regression analyses and administered separately for the observations measured with meaning‐recall and form‐recall tests. The results revealed that the average percentage learning gains were 60.1% and 58.5% on meaning‐recall and form‐recall immediate posttests. These gains dropped to 39.4% and 25.1% on delayed meaning‐ and form‐recall tests, respectively. These results suggest that learning through word‐focused tasks is far from guaranteed. Moreover, the percentage learning gains among the different activities ranged from 18.4% to 77.0% on immediate posttests and from 23.9% to 73.4% on delayed posttests indicating that there is much variation in efficacy among the activities. Moderator analyses revealed that learners’ place of study and direction of learning affected learning.

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 it
