There is no composed confirmation which can let us know precisely who has instituted the adage instructive innovation. Diverse educationists, researchers and scholars at various time interims have put sent distinctive meanings of Educational Technology. Instructive innovation is a multifaceted and incorporated procedure including individuals, system, thoughts, gadgets, and association, where innovation from various fields of science is obtained according to the need and necessity of training for actualizing, assessing, and overseeing answers for those issues required in all parts of human learning.

Instructive innovation, comprehensively, has gone through five phases.

The primary phase of instructive innovation is combined with the utilization of helps like outlines, maps, images, models, examples and solid materials. The term instructive innovation was utilized as equivalent words to varying media helps.

The second phase of instructive innovation is connected with the 'electronic insurgency' with the presentation and foundation of complex equipment and programming. Utilization of different varying media helps like projector, enchantment lamps, recording device, radio and TV got a progressive change the instructive situation. In like manner, instructive innovation idea was taken as far as these complex instruments and types of gear for powerful presentation of instructional materials.

The third phase of instructive innovation is connected with the improvement of broad communications which thusly prompted 'correspondence unrest' for instructional purposes. PC helped Instruction (CAI) utilized for training since 1950s additionally got to be prominent amid this time.

The fourth phase of instructive innovation is perceivable by the individualized procedure of guideline. The creation of customized learning and modified direction gave another measurement to instructive innovation. An arrangement of self-learning in light of self-instructional materials and showing machines developed.

The most recent idea of instructive innovation is impacted by the idea of framework designing or framework approach which concentrates on dialect research facilities, showing machines, modified guideline, mixed media advancements and the utilization of the PC in direction. As indicated by it, instructive innovation is an efficient method for outlining, completing and assessing the aggregate procedure of educating and learning as far as particular destinations taking into account research.

Instructive innovation amid the Stone Age, the Bronze Age, and the Iron Age

Duringthe Stone Age, ignition of discharge by rubbing stones, production of different carefully assembled weapon and utensils from stones and garments practice were a portion of the straightforward innovative advancements of most extreme significance. A small amount of Stone Age individuals created sea commendable outrigger kayak ship innovation to relocate starting with one place then onto the next over the Ocean, by which they built up their first casual training of information of the sea streams, climate conditions, cruising practice, astronavigation, and star maps. Amid the later Stone Age time frame (Neolithic period),for farming practice, cleaned stone apparatuses were produced using an assortment of hard shakes to a great extent by burrowing underground passages, which can be considered as the initial phases in mining innovation. The cleaned tomahawks were effective to the point that even after appearance of bronze and iron; individuals utilized it for clearing backwoods and the foundation of yield cultivating.
