The next period of educational technology is associated with the growth of bulk press which often generated 'transmission revolution' for instructional purposes. Computer-assisted Training (CAI) used for training since 1950s also turned common in this era.

The next point of educational technology is real by the individualized procedure for instruction. The creation of designed learning and designed instruction presented a brand new aspect to instructional technology. A method of self-learning predicated on self-instructional resources and teaching machines emerged.

The newest idea of educational technology is influenced by the thought of program engineering or system approach which is targeted on language labs, training machines, designed training, multimedia technologies and the use of the pc in instruction. In accordance with it, academic engineering is an organized means of developing, carrying out and analyzing the total procedure for teaching and learning in terms of unique objectives based on research.Educational write for us technology
engineering, despite the uncertainty of the origin of the word, can be traced back again to the time of the three-age program periodization of individual prehistory; particularly the Rock Age, the Bronze Era, and the Iron Age.

Duringthe Rock Age, ignition of fire by scrubbing rocks, production of various handmade tool and products from stones and clothing practice were a few of the simple technical developments of maximum importance. A portion of Stone Age people created ocean-worthy outrigger canoe ship technology to travel from place to a different across the Ocean, by that they created their first casual training of knowledge of the sea currents,

temperature situations, cruising exercise, astronavigation, and star maps. During the later Rock Era period (Neolithic period),for agricultural exercise, refined rock methods were made from many different difficult rocks mainly by searching undercover tunnels, which may be considered as the initial steps in mining technology. The refined axes were so successful that even after appearance of bronze and metal; persons tried it for removing forest and the establishment of plant farming.
