This technology is more up-close and personal than video conferencing. DVC relies on very specialized, powerful desktop computers. It utilizes a video camera, a microphone, and software to link users from different sites. Distance learning, on the other hand, connects teachers and learners, without regard to geographical location, through similar technologies. The main difference in the technologies is the interaction.
Distance learning relies on a more interactive, real-time model.
The Evolution of Teaching Within the last 20 years, a new vision of teaching has emerged, strongly influenced by social and cognitive sciences. In addition, the traditional view of teaching as telling or delivering curricula has turned to a socially-constructed view where instructors model expert practice and promote learning conversations that negotiate meaning to promote change in learner concepts. Teachers have turned from role of evaluator to advisors, managers, and facilitators of learning. Distance education has been involved and adds to the evolution of teaching. In a distance education classroom, technology makes available communication among students to instructors, students to students, and instructors to instructors.
