History of Educational Technology


There is not any written proof that could tell us exactly who has coined the word instructional generation. Different educationists, scientists, and philosophers have positioned forwarded specific definitions of Educational Technology at specific time durations. Educational technology is a multifaceted and integrated process involving human beings, system, ideas, devices, and employer, in which era from exclusive fields of technology is borrowed as in keeping with the need and requirement of education for imposing, comparing, and dealing with answers to those problems worried in all aspects of human getting to know.


The first degree of educational generation is coupled with aids like charts, maps, symbols, fashions, specimens, and concrete substances. The term instructional technology changed into used as synonyms for audio-visual aids. The 2nd degree of instructional technology is related to the ‘digital revolution’ with the creation and establishment of state-of-the-art hardware and software. The use of diverse audio-visible aids like a projector, magic lanterns, tape-recorder, radio, and television added a progressive exchange inside the educational scenario. Accordingly, instructional generation idea changed into these sophisticated contraptions and equipment for effective presentation of educational materials.

The 0.33 stage of educational generation is connected with the improvement of mass media, which brought about the ‘verbal exchange revolution’ for educational purposes. Computer-assisted Instruction (CAI) is used for schooling because the 1950s also have become popular in the course of this period. The fourth stage of the instructional era is discernible utilizing the individualized system of preparation. The invention of programmed studying and programmed coaching provided a new dimension to the academic era. A gadget of self-studying primarily based on self-instructional materials and teaching machines emerged.

The modern-day idea of tutorial technology is prompted by the idea of mechanical engineering or system approach, which specializes in language laboratories, coaching machines, programmed coaching, multimedia technology, and the pc in preparation. According to it, academic technology is a scientific way of designing, carrying out, and comparing the entire teaching process and learning in terms of precise targets based totally on studies. Educational technology, notwithstanding the uncertainty of the starting place of the term, may be traced to the time of the 3-age device periodization of human prehistory, specifically the Stone Age, the Bronze Age, and the Iron Age.


During the Stone Age, ignition of the fireplace with the aid of rubbing stones, manufacture of numerous hand-crafted weapons and utensils from stones, and garb exercise were a number of the simple technological trends of extreme importance. A fraction of Stone Age human beings developed ocean-worth outrigger canoe ship era to migrate from one location to another throughout the Ocean. They advanced their first informal schooling of knowledge of the sea currents, climate conditions, cruising practice, astronavigation, and star maps. During the later Stone Age duration (Neolithic period), for agricultural exercise, the polished stone gear had been made from a selection of tough rocks in large part by using digging underground tunnels, which may be taken into consideration as the first steps in the mining era. The polished axes were so powerful that even after the appearance of bronze and iron, humans used them for clearing the wooded area and the status quo of crop farming.

Although Stone Age cultures left no written statistics, archaeological evidence proved their shift from a nomadic existence to agricultural settlement. Ancient gear conserved in one of a kind museums, cave artwork like Altamira Cave in Spain, and different prehistoric art, including the Venus of Willendorf, Mother Goddess from Laussel, France. Are several pieces of evidence in favor of their cultures. The Neolithic Revolution of the Stone Age resulted in the advent of the Bronze Age with the improvement of agriculture, animal domestication, and the adoption of everlasting settlements. For these practices, Bronze Age humans evolved metal smelting, with copper and later bronze, an alloy of tin and copper, being the substances in their preference.

The Iron Age people replaced bronze and evolved the understanding of iron smelting generation to lower dwelling prices. Iron utensils have been stronger and less expensive than bronze equivalents. In many Eurasian cultures, the Iron Age turned into the last length earlier than the improvement of written scripts. Educational generation for the duration of the period of Ancient civilizations According to Paul Saettler, 2004, Educational technology can be traced returned to the time whilst tribal priests systematized bodies of expertise and historic cultures invented pictographs or sign writing a document and transmit information. At each level of human civilization, you can find an academic method or set of processes meant to enforce a specific way of life, supported by several investigations and evidence. The extra advanced the culture, the greater the complicated became the generation of instruction designed to reflect the unique ways of individual and social behavior supposed to run an educated society. Over centuries, each giant shift in instructional values, goals, or objectives brought about diverse education technologies.

The greatest advances in generation and engineering came with the rise of historical civilizations. These advances stimulated and knowledgeable different societies in the global to adopt new ways of dwelling and governance. The Indus Valley Civilization changed into an early Bronze Age civilization, which turned into located within the northwestern location of the Indian Subcontinent. The civilization was basically flourished across the Indus River basin of the Indus and the Punjab region, extending up to the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab (most of the element is under today’s Pakistan and the western states of current-day India as well as a few parts of the civilization extending to southeastern Afghanistan, and the easternmost a part of Balochistan, Iran).

There is a long time controversy to make sure approximately the language that the Harappan people spoke. It is believed that their writing turned into a minimum seems to be or a pictographic script. The script seems to have had about four hundred simple signs, with plenty of versions. People write their script with the course, usually from right to left. Most of the writing turned into determined seals and sealings, which had been in all likelihood utilized in change and respectable & administrative paintings.

Harappan human beings had the understanding of the measuring gear of length, mass, and time. They were the primary within the international to develop a device of uniform weights and measures. In a look at finished by way of P. N. Rao et al. In 2009, published in Science, computer scientists discovered that the Indus script’s pattern is towards spoken words, which supported the proposed hypothesis that it codes for an as-yet-unknown language.

According to the Chinese Civilization, a number of the most important techno-offerings from China encompass paper, early seismological detectors, lavatory paper, suits, iron plow, the multi-tube seed drill, the suspension bridge, the wheelbarrow, the parachute, herbal gas as gasoline, the magnetic compass, the raised-relief map, the blast furnace, the propeller, the crossbow, the South Pointing Chariot, and gunpowder. With the invention of paper, they have got given their first step in the direction of tutorial generation trends by way of similarly culturing one of a kind handmade products of paper as a way of visual aids.

Ancient Egyptian language becomes at one factor one of the longest surviving and used languages in the international. Their script turned into pics of actual things like birds, animals, exclusive tools, and many others. These snapshots are popularly known as a hieroglyph. Their language changed into made of above 500 hieroglyphs, which might be called hieroglyphics. The stone monuments or tombs that were discovered and rescued later on present evidence of many creative hieroglyphics styles in historical Egypt.

Paper and the pulp papermaking method, which changed into advanced in China all through the early second century AD, became carried to the Middle East and unfolded to the Mediterranean by way of the Muslim conquests. Evidence aid that a paper mill also became installed in Sicily inside the 12th century. The spinning wheel’s discovery expanded the productivity of thread-making manner to a great quantity, WhileLynn White delivered the spinning wheel with an increasing supply of rags; this brought about the manufacturing of cheap paper, which changed into a prime element within the development of printing generation.
