Examples of apps on the platform include an interactive graphing calculator that can send graphs to classmates, an interactive chemistry lab service, a a print your own scantron application and social multiplayer math games. Applications include BrainNook, Schooltube, StudyEgg, Third World Farmer and GradeCam. In addition, textbook publishers have their learning apps on the new platform. They’re not textbooks, but “modular” pieces of content, Borg says, and not just text but also interactive content.
