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 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
