Distance instruction is learner-centered—that is, it enables learners to tailor the instruction that they are receiving to meet their individual needs. Some distance programs use print media, some use telecommunications, and many use both, but geographic and time separation of the student and the teacher is a fundamental characteristic of distance education. Multimedia instruction with networked computers, video systems, or television may be used to connect the local classroom to learners at a distance. Satellite, compressed video, and fiber-optic systems are increasingly used for same-time, different-place education. This approach is also called synchronous distance learning. Students can also learn at different times and in different places. This approach is called asynchronous distance learning.

Interactive instruction is possible because the technologies used permit the learner to contact databases, information sources, instructional experts, and other students in real-time and interactive ways. For example, individual students can use their computers to contact other students or individuals who have information they need. Entire classes can participate in interactive video sessions with teachers from remote sites or with groups of students from other schools. An instructor can orchestrate the individual learning activities of students who collaborate with other learners, with the teacher, and with multimedia technology available locally or via the Internet. Distance learning encourages collaboration without the limitations of time and location inherent to the brick-and-mortar classroom.
