This series presents substantial results from around the globe in selected areas of educational research. The field of education is consistently on the top of priority lists of every country in the world, yet few educators are aware of the progress elsewhere. Many techniques, programs and methods are directly applicable across borders.This series attempts to shed light on successes wherever they may occur in the hope that many wheels need not be reinvented again and again.
