This document reports the results of work in identifying promising approaches to the provision of technological update to vocational/technical teachers, and discusses barriers and facilitators to the use of these approaches. Technological update refers to the technical knowledge and skills needed by vocational/technical teachers to provide students with the up-to-date technological preparation needed in the current work world. After information was gathered from the field, literature, knowledgeable observers, and vocational education institutions and agencies, researchers applied cost-effectiveness, complexity and locus of administrative control criteria to select those approaches that offer promise for secondary and postsecondary vocational/technical teachers. These approaches are described in general terms, and descriptions are provided of specific programs that exemplify each approach. Two different kinds of approaches were identified and are reported in the document. First, six specific delivery techniques are described: work experience internships; university and college course work; workshops, conferences, and seminars; industry observation; education and industry staff exchange; and part-time employment. Second, three different types of update programs are described: local programs, nonlocal programs, and industry training and updating programs. The result is nine descriptions of promising approaches to the task of providing technological update, each with its own potential for providing update, administrative characteristics, advantages, disadvantages, and barriers and facilitators. The need for further research on locating and generating funds for updating programs is suggested. (KC)
