The document discusses two approaches to educational technology: the software approach and the system approach. The software approach uses principles of psychology and behavioral science to modify learning through tools like films, flashcards, and tapes. It is closely associated with programmed learning. The system approach views education as a complex system and applies a scientific method to solve administrative problems through setting goals, analyzing resources, planning actions, and continuous evaluation. It links the software and hardware approaches to make the educational system function effectively and efficiently.
