An interactive videodisc module for forage quality and testing instruction

An interactive videodisc teaching module has been prepared on the subject of forage quality and testing. This module uses the USDA Extension Service Interactive Video Extension Network (IVEN) share disc for the visual images and a microcomputer diskette for the text and audio tracks. The random access nature of this medium allows for any image of the disc to be recalled within 3 s, offering significant improvement over linear teaching technologies. This module was designed for and has been used successfully in undergraduate teaching and extension forage education programs, providing an interactive rather than a passive teaching environment. Information for the module was obtained from college textbooks, extension circulars, and the collective experience of research, teaching, and extension personnel. Standard videodisc and microcomputer equipment are used to operate the educational module.
