Abstract
Zhang analyses the phenomenon of private supplementary tutoring from a global perspective. The expansion of such tutoring alongside schooling is among the striking global shifts since the turn of the century. In many countries over half of the relevant cohorts of children receive private tutoring, with that proportion in some locations exceeding 80%. The sector has far-reaching implications for social inequalities, (in)efficiencies in educational processes, study burdens on students, family finances, innovation, and employment. Yet greatly-needed government regulations have typically been slow to catch up with the phenomenon.Commentary in the volume juxtaposes countries with strong regulations with counterparts having weak regulations. Conceptually, the book considers forces changing the roles of multiple stakeholders, including governments, entrepreneurs, teachers, families and students.A useful read for students and researchers interested in comparative education and governance.

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.
