Conducting Research into Private Supplementary Tutoring: Methods and Approaches
Research on private supplementary tutoring has greatly expanded， and has improved understanding of its nature and implications. However， much remains to be done.

Particular care is needed when making international comparisons. Nevertheless，the research arena is improving.
