Interactive videodisc (IVD) offers a combination of media with practical applications in vocational education. IVD is superior to videotapes and other media in quality, applicability, and effectiveness. IVD can be used in different settings and for a variety of instructional applications. Although not appropriate for every learning situation, IVD has strengths, including student control of the interaction, instant feedback, and a two-way dialogue that engages the learner mentally and physically. Vocational educators have applied IVD in various ways: to teach employability skills; to provide remedial instruction for technical students with low math skills; to provide training in safety, security, and quality standards through simulation of workplace problems; and to provide tutorial and simulation of the use of a welding torch. Key factors in using IVD in vocational education are related to instructional design, teacher role, and costs. A basic question is whether IVD is the appropriate medium for the subject or situation. IVD, a highly learner-centered medium, definitely changes the role of the teacher, who acts more as a resource person or facilitator. Although cost seems to be a barrier, most equipment is modular and additions can be made over time. (11 references) (YLB)
