South Korea's education system is one of the best in the world. It has a goal of having all of its textbooks delivered digitally to its students by 2015. Gone will be traditionally bound paper books; now their books will be available on personal computers, laptops, internet TVs and the fastest growing digital devices, tablets such as the iPad. A recent study by the Department of Educational Research at Lancaster University found that use of digital technology in the classroom increased student engagement in learning and could save schools money in the long run. Apple recently reported that 600 of the 14,000 school districts in the U.S. are switching to digital textbooks using iPads.
