Abstract

fetched live from OpenAlex

Textbooks are a crucial tool in English as a foreign language (EFL) contexts where out-ofthe-classroom use of English is minimal. Vocabulary is an essential component of language learning; thus, EFL textbooks should sufficiently represent vocabulary needed for students' academic success. Due to the growing demand for English proficiency locally and internationally, Bangladeshi EFL textbooks' lexical coverage is examined to determine if vocabulary input is aiding students in their K-12 education and their transition to higher education. A corpus-based analysis of the Bangladeshi K-12 textbooks' vocabulary has been conducted, and the vocabulary of university textbooks is compared to the K-12 vocabulary. Results demonstrate that the transitions to academic stages are not easy, as the lexical input found in early-grade textbooks leaves significant gaps in vocabulary found in textbooks of the later grades, and similar results were found in the transition to tertiary levels. Pedagogical implications and recommendations are also discussed.

Full frame distilled prediction

Teacher imitation

Not 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.
