In order to identify and document the pervasive trends in the field of educational technology, an elaborate content review of the professional literature was performed. Literature examined included journals, conference proceedings, ERIC Resources in Education (RIE) documents, annuals and yearbooks, and dissertations. The trends that were identified include: (1) the design, development and evaluation of instructional materials and procedures are a primary concern among practitioners of educational technology; (2) professional education for teachers in the use of educational technology principles and practices is seen as a basic need for present and future professional service; (3) distance education is becoming a significant delivery system; (4) the computer is the dominant medium in the field, and telecommunications and video follow close behind; (5) the role of the educational technologist is unclear and varies from location to location; (6) case studies serve as models to follow in the implementation of educational technology applications; (7) the field of educational technology is concerned about its status as a profession; and (8) educational technology principles, products, and practices are just beginning to be integrated into courses and curricula.
