In most cases the learning outcomes are the same . The differences are differences in the quality of teaching not in the delivery channel. TeleLearning is synchronous, largely teacher paced, and highly interactive. Students can view slide shows on the large computer screen at the same time the teacher is talking. The displayed images can be captioned and overwritten in real time.
Teachers teach the way that they have been trained to teach.
Their experience in the classroom transfers to this medium. TeleLearning is an effective way, both economically and educationally, to deliver highly interactive instruction or training over distance. TL costs about the same as a conventionally taught class. Unlike televised or videotaped instruction, there is no way to spread production costs over several large classes. What makes TL work is the fact that it is as interactive as a conventional classroom.
