This document discusses augmented reality (AR) and its uses in education. It begins by defining AR as using devices with cameras to overlay digital information on real-life objects. Examples of AR applications described include using markers or QR codes to access 3D models, videos, and interactive content related to topics like science, math, language arts and more. The document also provides examples of how teachers and students in Roanoke County Schools have created and used their own AR content to engage learners and bring historical figures and places to life through mobile devices.
