Educational technology is the effective use
of technological tools in learning. As a concept, it concerns an array of
tools, such as media, machines and networking hardware, as well as considering
underlying theoretical perspectives for their effective application.
Educational technology is not restricted to high technology. Nonetheless,
electronic educational technology, also called e-learning, has become an
important part of society today, comprising an extensive array of digitization
approaches, components and delivery methods. For example, m-learning emphasizes
mobility, but is otherwise indistinguishable in principle from educational
technology. Educational technology includes numerous types of media that
deliver text, audio, images, animation, and streaming video, and includes
technology applications and processes such as audio or video tape, satellite
TV, CD-ROM, and computer-based learning, as well as local intranet/extra net and
web-based learning. Information and communication systems, whether
free-standing or based on either local networks or the Internet in networked
learning, underlie many e-learning processes. Theoretical perspectives and
scientific testing influence instructional design. The application of theories
of human behavior to educational technology derives input from instructional
theory, learning theory, educational psychology, media psychology and human
performance technology. Educational technology and e-learning can occur in or
out of the classroom. It can be self-paced, asynchronous learning or may be
instructor-led, synchronous learning. It is suited to distance learning and in
conjunction with face-to-face teaching, which is termed blended learning.
Educational technology is used by learners and educators in homes, schools
(both K-12 and higher education), businesses, and other settings.
