History of Educational Technology


No written proof could tell us exactly who coined the word instructional generation. Different educationists, scientists, and philosophers have proposed specific definitions of educational technology at particular time durations. Educational technology is a multifaceted and integrated process involving human beings, systems, ideas, devices, and employers, in which era from exclusive fields of technology is borrowed 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 a synonym 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. Using diverse audio-visible aids like a projector, magic lanterns, tape-recorder, radio, and television added a progressive exchange inside the educational scenario. Accordingly, the instructional generation ideas changed into these sophisticated gadgets and equipment to effectively present 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, in the 1950s, it also became popular. The fourth stage of the instructional era is discernible by utilizing the individualized preparation system. The invention of programmed studying and coaching provided a new dimension to the academic period. 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 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 teaching process and learning in terms of precise targets based on studies. Notwithstanding the uncertainty of the starting place of the word, educational technology 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, the ignition of the fireplace with the aid of rubbing stones, the manufacture of numerous hand-crafted weapons and utensils from rocks, and garb exercise were some of the simple technological trends of extreme importance. A fraction of Stone Age humans developed the 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 (Neolithic period), for agricultural purposes, the polished stone gear was made from a selection of tough rocks in large part by digging underground tunnels, which may be considered 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 to clear the wooded areas and maintain the status quo of crop farming.

Although Stone Age cultures left no written statistics, archaeological evidence proved their shift from a nomadic existence to an agricultural settlement. Ancient gear is 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 improved 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, as the substances they preferred.

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 was the last length before 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 to when tribal priests systematized bodies of expertise and historic cultures invented pictographs or writing a document and transmitted 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 more advanced the culture, the greater the complexity of the instruction generation designed to reflect the unique ways of individual and social behavior 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 educated different societies worldwide 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 culture 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 has been a long-time controversy about the language the Harappan people spoke. It is believed that their writing turned into a minimum of a pictographic script. The script appears to have had about four hundred simple signs, with plenty of versions. People write their hand 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 humans understood the measuring gear of length, mass, and time. They were the primary ones within the international community to develop a uniform weights and measures device to look at the 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. The invention of paper has been their first step in the direction of tutorial generation trends by cultivating one-of-a-kind handmade writing products as visual aids.

The Ancient Egyptian became one of the world’s longest-surviving and most used languages. Their script became pics of things like birds, animals, exclusive tools, and many others. These snapshots are popularly known as a hieroglyph. Their language changed into more than 500 hieroglyphs, called hieroglyphics. The stone monuments or tombs discovered and rescued later present evidence of many creative hieroglyphic styles in historical Egypt.

The paper and pulp papermaking method, which advanced in China all through the early second century AD, became carried to the Middle East and unfolded to the Mediterranean through the Muslim conquests. Evidence shows that a paper mill also became installed in Sicily in the 12th century. The spinning wheel’s discovery expanded the productivity of thread-making manner to a great quantity, while Lynn 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.
