Becoming more global is a familiar refrain for many a school administrator or curriculum developer wrestling with delivering 21st century skills. Over the past decade, districts have expanded their foreign language programs, added Mandarin Chinese to the mix, and in some cases launched language immersion classes in their elementary schools. Others have opened entire schools designed around international education. Not only do these schools promote proficiency in one or more foreign languages, but they also embed international perspectives in all content areas, from social studies to the arts, and they make extensive use of online learning to interact with students and teachers in other countries. But while initiatives like these were often regarded as experimental or, at best, unique just a few years ago, a growing number of school districts are taking global learning to the next level by replicating schools with a global bent.
