Distance Education, distance learning is a field of education that focuses on the pedagogy, technology, and instructional systems design that aim to deliver education to students who are not physically "on site". Distance learning courses that require a physical on-site presence for any reason including the taking of examinations is considered to be a hybrid or blended course of study.
Many teachers feel the opportunities offered by distance learning outweigh the obstacles. In fact, instructors often comment that the focused preparation required by distance teaching improves their overall teaching and empathy for their students. Through Distance learning they can:
Reach a wider student audience
Provide opportunity to students who are unable to attend on-campus classes
Involve outside speakers who would otherwise be unavailable
Link students from different social, cultural, economic, and experiential backgrounds
