Instructional television (ITV) is the use of television programs in the field of distance education. Educational television programs on instructional television may be less than one half hour long (generally 15 minutes in length) to help their integration into the classroom setting. These shows are often accompanied by teachers' guides that include material to help use this program in lessons. Instructional television programs are often shown during the daytime on Public Broadcasting Service (PBS) stations in the United States. However, fewer public television stations devote their airtime to ITV today than they do in the past; these days, ITV programs are either seen on a digital subchannel of Non-commercial educational public television station, or passed on to a local Educational-access television channel run by a Public, educational, and government access (PEG) cable TV organization.
Instructional television has been granted 20 microwave channels, administered by local educational institutions, through a service known in the USA as ITFS, or Instructional Television Fixed Service. Instructional television may also be programmed on Terrestrial television stations.
Famous quotes containing the word television:
“The television screen, so unlike the movie screen, sharply reduced human beings, revealed them as small, trivial, flat, in two banal dimensions, drained of color. Wasn’t there something reassuring about it!—that human beings were in fact merely images of a kind registered in one another’s eyes and brains, phenomena composed of microscopic flickering dots like atoms. They were atoms—nothing more. A quick switch of the dial and they disappeared and who could lament the loss?”
—Joyce Carol Oates (b. 1938)
