Instructional technology and design involves using technology like audio, visual, and interactive tools to present information to students. The chalkboard was once considered a technological tool but is now seen as outdated, showing how technology definitions have changed. E-mail allows schools to provide learning resources electronically, enabling access that was previously unavailable. For example, Oregon provided all students with Google email addresses to access online educational materials from the state department of education. Electronic reading devices also give new ways for authors to organize and market books, with some combining video and text in hybrid formats sold through iTunes.
