At its core, distance education is instruction conducted via technologies that significantly or completely eliminate the traditional face-to-face exchanges of teachers and students. Today, many programs falling under the rubric of distance education combine mediated and face-to-face encounters
with instructors. In the future even limited face-to-face interactions will fade, replaced by technologies such as desktop interactive video conferencing. According to many forecasts, the notion of any sort of immediate teacher-student interaction, whatever the media, may disappear in favor of facilitated, self-paced instructions through the computer.
