History of Educational Technology

No written proof could inform us precisely who has coined the phrase educational generation. Different educationists, scientists, and philosophers have positioned forwarded unique definitions of Educational Technology at special time durations. Educational generation is a multifaceted and incorporated manner involving humans, system, ideas, gadgets, and employer, in which generation from special fields of technology is borrowed as per the want and requirement of education for enforcing, comparing, and handling solutions to the ones troubles involved in all aspects of human getting to know.


The first degree of tutorial technology is coupled with aids like charts, maps, symbols, fashions, specimens, and urban materials. In the time period, educational technology changed into used as synonyms to audio-visible aids.

The second level of educational technology is associated with the ‘digital revolution’ with the introduction and status quo of sophisticated hardware and software programs. The use of numerous audio-visible aids like a projector, magic lanterns, tape-recorder, radio, and tv introduced a progressive trade inside the instructional situation. Accordingly, the instructional era concept was taken in terms of these state-of-the-art instruments and equipment for a powerful educational substance presentation.

The 1/3 stage of instructional generation is related to mass media development, which caused the ‘communication revolution’ for educational purposes. Computer-assisted Instruction (CAI) is used for education, given that the Fifties additionally have become popular throughout this era.

The fourth degree of the instructional era is discernible by the individualized procedure of preparation. The invention of programmed getting to know and programmed training supplied a new measurement to academic technology. A system of self-gaining knowledge primarily based on self-educational substances and coaching machines emerged.

Today’s tutorial technology concept is encouraged through the idea of device engineering or gadget technique, which focuses on language laboratories, coaching machines, programmed instruction, multimedia technology, and the usage of the computer in guidance. According to it, instructional technology is a scientific way of designing, carrying out, and comparing the overall teaching methods and mastering in terms of unique objectives primarily based on studies.

Educational technology for the duration of the Stone Age, the Bronze Age, and the Iron Age
Despite the uncertainty of the beginning of the term, the educational era can be traced back 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, the ignition of fire utilizing rubbing stones, the manufacture of numerous handmade weapons and utensils from stones, and apparel practice had been some of the simple technological developments of maximum significance. A fraction of Stone Age people advanced ocean-worthy outrigger canoe ship era emigrate from one vicinity to any other across the Ocean, using which they advanced their first informal education of understanding of the sea currents, weather situations, sailing exercise, astronavigation, and big-name maps. During the later Stone Age period (Neolithic period), for agricultural exercise, polished stone tools had been crafted from a spread of tough rocks in large part with the aid of digging underground tunnels, which can be considered as the first steps in the mining era. The polished axes were so powerful that even after the look of bronze and iron, humans used them for clearing the wooded area and the established order of crop farming.


Although Stone Age cultures left no written information, archaeological evidence proved their shift from nomadic lifestyles to agricultural settlement. Ancient gear conserved in exclusive museums, cave artwork like Altamira Cave in Spain, and different prehistoric art, including the Venus of Willendorf, Mother Goddess from Laussel, France, and so on. Are some of the 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 further developed steel smelting, with copper and later bronze, an alloy of tin and copper, and their chosen materials.

In the Iron Age, human beings changed to bronze. They advanced the know-how of iron smelting technology to decrease dwelling prices since iron utensils were more potent and inexpensive than bronze equivalents. In many Eurasian cultures, the Iron Age become the remaining duration before the improvement of written scripts.

According to Paul Saettler, 2004, an Educational era may be traced returned to the time when tribal priests systematized bodies of know-how and ancient cultures invented pictographs or signal writing to report and transmit facts. In each level of human civilization, one can locate an instructional technique or set of methods supposed to put into effect a specific tradition that had been additionally supported with the aid of several investigations and evidence. The extra advanced the tradition; the extra complex became the technology of guidance designed to mirror unique ways of person and social behavior intended to run an educated society. Over centuries, every considerable shift in academic values, desires, or goals led to numerous education technology.

The Indus Valley Civilization became an early Bronze Age civilization that changed into positioned within the northwestern place of the Indian Subcontinent. The civilization became frequently flourished across the Indus River basin of the Indus and the Punjab place, extending up to the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab (most of the component is beneath modern Pakistan and the western states of cutting-edge-day India as well as some part of the civilization extending to southeastern Afghanistan, and the easternmost part of Balochistan, Iran).

There is a long-term controversy to make sure approximately the language that the Harappan human beings spoke. It is assumed that their writing becomes at least seems to be or a pictographic script. The script seems to have had approximately four hundred simple signs, with masses of variations. People write their script with the direction normally from proper to left. Most of the writing was found on seals and sealings, which have been probably utilized in change and official & administrative work.


According to the Chinese Civilization, a number of the most important techno-offerings from China consist of paper, early seismological detectors, toilet paper, suits, iron plow, the multi-tube seed drill, the suspension bridge, the wheelbarrow, the parachute, natural fuel as fuel, 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 towards the instructional era’s tendencies by similarly culturing extraordinary homemade merchandise of paper as the manner of visible aids.
