Explicit Lexical Elaboration as an Autonomy Enhancing Tool for Acquisition of L2 Vocabulary from Reading
Bibliographic record
Abstract
Studies (Kim, 1996, 2006; Silva, 2000, for example) indicate that explicit lexical elaboration is the most significant technique to make the meaning of unknown words clear in the text. Through explicit lexical elaboration, definitions or synonyms of the difficult words in the text are provided after the explicit elaborative devices such as which means whereas appositive devices are used in implicit lexical elaboration. This study was an experiment to show that explicit and implicit lexical elaborative devices can serve as autonomy enhancing tools which assist L2 learners in recognizing the meaning of the unknown words in a text in the absence of dictionaries and instructors. To do the study, three groups of EFL participants (each group including 45 participants) were exposed to 30 low-frequency words by reading one of the three versions of an experimental text containing these words. A univariate factorial ANOVA was administered to analyze the data of the study. The results of the study showed that explicit lexical elaboration was the most beneficial technique in meaning recognition of L2 vocabulary in the text. It is also implied from the results of the study that the explicit elaborative device creates the best condition for learners’ autonomy in acquiring L2 vocabulary from reading. Key words: explicit and implicit lexical elaboration; learner autonomy enhancement; meaning recognition

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.
