Fostering interaction has been one of the primary goals for distance educators in an effort to close the physical distance between teachers and students. This interaction has been attempted using both technological and instructional means.

Before the invention of computers, the primary delivery means for distance education was print, a reliable medium but slow in facilitating feedback.
