The document discusses using iPads as a language learning tool. It outlines the four stages of innovation development: need, research, development, and commercialization. For need, iPads would replace a costly language lab and each student would have their own device. Research shows language learning apps on iPads provide authentic materials and social networking. The development is intended for both teachers and learners, though cost is a problem. Commercialization saw over 14.8 million iPads sold in the first year, and schools are providing electronic books on iPads instead of paper textbooks.
