The origins of distance education can be traced to mid-19th century Europe and the United States. The postal system was the best technology that pioneers could use in their day. It was started to open educational opportunities to people who wanted to learn but were not able to attend conventional schools. Those with physical disabilities, women who were not allowed to enroll in institutions open only to men, people who had jobs during normal school hours, and those who lived in remote regions where schools did not exist are the people who most benefitted from distance education.
In 1872, American university level distance education began at Illinois Wesleyan University. Bachelor and graduate degrees could be obtained in absentia. The Chautauqua movement in about 1882 gave the popular push to correspondence education.
In 1915, accreditation of college and university distance programs fell to the National University Extension Association. And in 1926, the National Home Study Council (NHSC) was formed to address the issues of quality and ethical practice that arose due to the popularity of the teaching of academic and vocation courses by correspondence in 1900.
Distance Education has developed as technology changed. The invention of education radio in the 1920s and the advent of television in the 1940s created important new forms of communication for use in distance education. The development of reliable long-distance telephone company in the early 1900s also increased the capacity of distance educators to reach new student population. But telephone systems only played a prominent role in distance education with the development of teleconferencing technologies in the 1980s and 1990s. And, with the spread of computer-network communication in the 1980s and 1990s, it allowed teachers to communicate in conferences through computers.
Today, distance education makes use of the internet where teachers and students present text, pictures, audio, and video. File sharing and communications tools like email, chats, and audio and video conferencing are integral part of the internet setup.
