In Cambodia, only 20% of students advance to junior high. To inspire kids to learn, college teacher Shuji Matsuoka and his Cambodian students have developed original teaching materials. It's a board game played on a map of Cambodia, teaching geography, spelling, and arithmetic through photos and simple text. Even the Cambodian government has recognized its value as a teaching tool. Matsuoka was inspired by Cambodian Aki Ra, a former child soldier who now clears landmines as a volunteer.
