This document defines distance education and discusses its history. Distance education involves physical or time separation between students and instructors, with educational technology used to connect them and transmit course content. It has existed since the 1700s through correspondence education, but technology-based distance education emerged in the early 1900s with audiovisual devices in schools. The history shows new technologies balanced against resistance to change, with distance education trying to blend with traditional education while adapting to evolving learning theories and technologies.
