This document provides an overview of distance education and defines some key terms. It begins by asking the reader to define distance education and discusses how it differs from traditional in-person education. The document then provides a 3-part definition: that distance education 1) focuses on pedagogy and technology to deliver education to students who are not physically on-site, 2) involves formal learning between students and instructors separated by geographic distance or time often using communications technology, and 3) happens when students are isolated from instructors by distance or time but can be connected through synchronous or asynchronous technologies. The document also briefly discusses the history of distance education media from early printed materials and broadcast technologies to modern synchronous and asynchronous digital tools.
