Researchers commonly interpret effect sizes by applying benchmarks proposed by Cohen over a half century ago.

Evaluating Chinese publications about rural education and needed reforms presents several problems: political limits on educational debate; paucity of statistical data and reference citations; and complex ideological statements.

This second edition has been updated to include current studies, policies, and practices. It includes discussions of the five stages for equity reform; tips for effectively…

Analyzes the use of relevant international data to inform educational policy. Notes that such data can be used to extend research on school effects by incorporating comparative data, by evaluating the trade-offs involved in attempts to raise national achievement levels, and by broadening the range of international data.
