A study examined the extent and nature of the problem of keeping secondary and postsecondary vocational and technical teachers in the United States up to date in the technology of their fields. During the study, 18 knowledgeable individuals were identified in 18 states to prepare papers on the need for and the problems of technological update of secondary and postsecondary vocational and technical teachers. Analysis of these papers indicates that large numbers of vocational and technical teachers at both the secondary and postsecondary levels are considered to have substantial or critical need for updating their knowledge of the technology of their field. Furthermore, this need exists for all occupational service areas examined. Despite the fact that a variety of approaches to technological update are being used, lack of resources in terms of money, time, and links with external organizations are seen as major barriers to the successful technological update of teachers. Among those approaches considered to have the greatest potential for successfully updating programs are workshops, conferences, and seminars as well as collaborative activities and programs among schools, business, and industry for teacher occupational experiences and curriculum content revision. Particularly needed is an overall teacher update plan that provides for effective selection, application, coordination, and management of the above-mentioned approaches. (MN)
