Let’s review some of the definitions of distance education from some experts.

Rudolf Manfred Delling: “Distance Education is a planned and systematic activity that comprises the choice, didactic preparations and presentation of teaching materials as well as the supervision and support of student learning and which is achieved by bridging the physical distance between student and teacher by means of at least one appropriate technical medium."

Grenville Rumble: “ In any distance education process, there must e a teacher; one or more students; a course or curriculum that the teacher is capable of teaching and the student is trying to learn; and a contract, implicit or explicit, between the student and the teacher or the institution employing the teacher, which acknowledges their respective teaching-learning roles.
