ABSTRACT:
An economical, practical method of bringing the major portion of a classroom teaching experience to a remote student. The teacher's oral and blackboard presentations are recorded, forwarded to the student and played back on equipment that reproduces the teacher's voice and his or her graphics that would normally be presented on a blackboard, retaining the time correlation between the spoken and written texts.
