There is no written evidence which can tell us exactly who has coined the phrase educational technology. Different educationists, scientists and philosophers at different time intervals have put forwarded different definitions of Educational Technology . A multifaceted and integrat process involving people, procedure, ideas, devices, and organization, where technology from different fields of science is borrow as per the need and requirement of education for implementing, evaluating, and managing solutions to those problems involved in all aspects of human learning. Broadly speaking, has pass through five stages. The first stage of educational technology is coupled with the use of aids like charts, maps symbols models specimens and concrete materials. The term educational technology was used as synonyms to audio-visual aids. The second stage of educational technology.
Computer-assisted Instruction (CAI) used for education since 1950s also became popular during this era. The fourth stage of educational technology is discernible by the individualized process of instruction. The invention of programmed learning and programmed instruction provided a new dimension to educational technology. A system of self-learning base on self-instructional materials and teaching machines emerged. The latest concept of education technology is influenc by the concept of system engineering or system approach which focuses on language laboratories, teaching machines, programme instruction, multimedia technologies and the use of the computer in instruction. According to it, education technology is a systematic way of designing, carrying out and evaluating the total process of teaching and learning in terms of specific objectives based on research.
Educational technology during the Stone Age, the Bronze Age, and the Iron Age
Educational technology, despite the uncertainty origin of the term, can traced back to the time of the three-age system periodization of human prehistor name the Stone Age the Bronze Age, and the Iron Age. During the Stone Age ignition of fire by rubbing stones manufacture of various handmade.

The more advanced the culture, the more complex became the technology of instruction designed to reflect particular ways of individual and social. Tended to run an educated society. Over centuries, each significant shift in educational values, goals or objectives led to diverse technologies of instruction. The greatest advances in technology and engineering came with the rise of the ancient civilizations. These advances stimulated and educated other societies in the world to adopt new ways of living and governance .
