Abstract
his study investigates the performance of a spell checker designed for native writers on misspellings made by second language (L2) learners. It addresses two research questions: 1) What is the correction rate of a generic spell checker for L2 misspellings? 2) What factors influence the correction rate of a generic spell checker for L2 misspellings? To explore these questions, the study considers a corpus of 1,027 unique misspellings from 48 Anglophone learners of German and classifies these along three error taxonomies: linguistic competence (competence versus performance misspellings), linguistic subsystem (lexical, morphological or phonological misspellings), and target modification (single-edit misspellings (edit distance = one) versus multiple-edit misspellings (edit distance > 1)). The study then evaluates the performance of the Microsoft Word® spell checker on these misspellings. Results indicate that only 62% of the L2 misspellings are corrected and that the spell checker, independent of other factors, generally cannot correct multiple-edit misspellings although it is quite successful in correcting single-edit errors. In contrast to most misspellings by native writers, many L2 misspellings are multiple-edit errors and are thus not corrected by a spell checker designed for native writers. The study concludes with computational and pedagogical suggestions to enhance spell checking in CALL.

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
