An Evaluative Review of Mobile-assisted L2 Vocabulary Learning Approaches based on the Situated Learning Theory
Bibliographic record
Abstract
There is a growing trend of utilizing mobile technology to develop effective contextual vocabulary learning methods based on the situated learning theory (SLT). In spite of substantial research on mobile-assisted vocabulary learning (MAVL), there have been few reviews of MAVL approaches, let alone evaluations of them based on the idea of SLT. To address this research gap, this study evaluated three types of MAVL approaches: (1) mobile message services, (2) vocabulary learning applications, and (3) digital simulation games according to the authenticity principle and characteristics of SLT. The evaluative review included in-depth examinations of two aspects: the extent to which these characteristics are manifested in each approach, and the way in which these characteristics are incorporated into the design of each approach. The result suggests that the MAVL approaches differ significantly, in terms of their authenticity and degree of correspondence to the SLT. This review offers practical implications for the development and improvement of MAVL approaches, as well as important suggestions for future research, all of which are believed to benefit the field of L2 vocabulary acquisition.

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.
