Distance education is defined as education that occurs when students and instructors are separated by physical distance and technology is used to connect them. It allows students to learn independently of location and time constraints. Historically, distance education began with correspondence courses delivered by mail and has evolved with new technologies like the internet and video conferencing to allow more interactive learning experiences across geographic distances. Key aspects of distance education include the physical separation of students and teachers, communication technologies used to deliver content and enable interaction, and independent study.
