Quick Reference


Sounds or pictures used to support or reinforce learning. These include such resources as slide projections, DVDs and videos, overhead projectors, sound recordings, radio, and television. Increasing use of electronic resources has led to this term falling increasingly out of use, to be replaced with information learning technology. Nevertheless, in many educational institutions the department or team responsible for supplying or maintaining teaching resources of this kind will still carry the designation ‘AV’ in its title.
