	Distance education - Wikipedia, the free encyclopedia
		Distance education, or distance learning, is a field of education that focuses on the pedagogy/andragogy, technology, and instructional systems design that are effectively incorporated in delivering education to students who are not physically "on site" to receive their education.
		In short then, though a range of technology presupposes a distance education 'inventory' it is technological appropriateness and connectivity, such as computer, or for that matter electrical connectivity that should be considered, when we think of the world as a whole, while fitting in technological applications to distance education.
		Distance education programs are sometimes called correspondence courses, an older term that originated in nineteenth-century vocational education programs that were conducted through postal mail.

	Distance
		In the case of two locations on Earth, usually the distance along the surface is meant: either "as the crow flies" (along a great circle) or by road, railroad, etc. Distance is sometimes expressed in terms of the time to cover it, for example walking or by car.
		A distance between two points P and Q in a metric space is d(P,Q), where d is the distance function that defines the given metric space.
		Alternatively, the distance between sets may indicate "how different they are", by taking the supremum over one set of the distance from a point in that set to the other set, and conversely, and taking the larger of the two values (Hausdorff distance).

		The innovations in computer and communications technologies combined with on-going needs to deliver educational programs to students regardless of their physical locations, have lead to the innovation of distance education programs and technologies.
		To keep up with recent developments in both areas of technologies and techniques related to distance education programs, educators, administrators, and researchers are in constant needs of learning about issues, solutions, and challenges of these technologies.
		The Encyclopedia of Distance Learning (4 volume set) is an excellent source of comprehensive knowledge and literature on the topic of distance learning programs.
