This resource book is one of a series of three information resources containing ideas about instructional technology applications and how certain technology applications may have particular relevance to vocational education. It contains descriptions of some instructional technology systems applications that are currently in use. The cases focus on: (1) two-way interactive television; (2) a networked computer-based laboratory; (3) an integrated information technology system; and (4) technology and training in the nuclear industry. For each component of each system reviewed in the cases, a need is shown, followed by an application and the outcome of that solution. The notebook is designed to help vocational educators make decisions about which technologies to use in their instructional settings and how to apply elements of various systems to their situations.
