Distance education is defined as a systematic approach to planned teaching and learning that uses a wide spectrum of technologies to reach learners at a distance. It is designed to encourage learner interaction and lead to formal learning certification. Distance education uses various technologies like video conferencing, discussion boards, email, prerecorded videos, and e-books to instruct students separated by distance and time zone. Historically, printed materials were used to distribute information to distant students, but modern distance education now utilizes many online technologies.
