South Korea moves to replace paper with digital textbooks for its tech-savvy students

Outside the classroom a hot summer day beckons, but fourth-grade teacher Yeon Eun-jung's students are glued to their tablet PCs as they watch an animated boy and a girl squabble about whether water becomes heavier when frozen. The small scene in this rural town is part of something big: South Korea is taking a $2 billion gamble that its students are ready to ditch paper textbooks in favor of tablet PCs as part of a vast digital scholastic network.

France, Singapore, Japan and others are racing to create classrooms where touch-screens provide instant access to millions of pieces of information. But South Korea - Asia's fourth-largest economy - believes it enjoys an advantage over these countries, with kids who are considered the world's savviest navigators of the digital universe. A 2009 study by the Organization for Economic Cooperation and Development, a Paris-headquartered grouping of wealthy nations, found 15-year-olds in South Korea scored highest in their ability to absorb information from digital devices, beating runners-up New Zealand and Australia by a large margin.
