Being an expert mathematics online tutor: what does expertise entail?
Bibliographic record
Abstract
This article is derived from the qualitative portion of a larger study conducted on mathematics websites that provide expert volunteer help. Data consist of tutoring logs of five expert tutors from two help sites, plus interviews with these tutors. The researcher has employed theories about expertise in the educational domain to elicit details of individual coping strategies with challenges posed by the online environment, including students’ non‐responsiveness and issues of academic honesty. One of the participants, a recent online tutor who was also a teacher, experienced conflict of professional interests between these two roles. Tutors, who were also students, felt a conflict of liability – towards the tutees on one hand and towards the website administration on the other. Except for one tutor who demonstrated a highly developed expert performance, other tutors exhibited characteristics of both novices and experts, thus placing themselves within temporary and context‐dependent locations on the novice‐expert continuum. Recommendations are offered herein for future research and for the organization of online tutoring environment. It is suggested that best practices must include both pedagogical and tutor training/support considerations.

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.
