Educational Technology's History

 There is no recorded evidence that identifies the person who invented the term "educational technology." At various times in history, many educators, scientists, and philosophers have proposed various definitions of Educational Technology. Educational technology is a comprehensive and integrated process involving people, procedure, ideas, gadgets, and organisation, in which technology from various fields of research is borrowed as needed for implementing, evaluating, and managing solutions to issues in all aspects of human learning.

In general, educational technology has gone through five stages.

The use of aids such as charts, maps, symbols, models, specimens, and concrete objects is combined with the initial stage of educational technology. The terms instructional technology and audio-visual aids were used interchangeably.

The 'electronic revolution,' which saw the introduction and establishment of sophisticated hardware and software, is related with the second stage of educational technology. The introduction of numerous audio-visual tools such as projectors, magic lanterns, tape recorders, radio, and television revolutionized the educational landscape. As a result, the educational technology idea was defined as these advanced instruments and equipment used to effectively display instructional information.

The third stage of educational technology is linked to the growth of mass media, which led to a "communication revolution" for educational reasons. During this time, computer-assisted instruction (CAI), which has been utilized in education since the 1950s, gained widespread.

The personalized approach of training distinguishes the fourth stage of educational technology. The invention of programmed learning and programmed instruction gave educational technology a whole new meaning. Self-instructional materials and teaching devices were used to create a self-learning system.

The notion of system engineering or system approach, which focuses on language laboratories, teaching machines, programmed instruction, multimedia technologies, and the use of the computer in instruction, has inspired the most recent notion of educational technology. Educational technology, according to it, is a systematic approach to planning, implementing, and assessing the entire teaching and learning process in terms of specified research-based objectives.

During the Stone Age, Bronze Age, and Iron Age, educational technology was developed.

Despite the fact that the term's origin is unknown, educational technology may be traced back to the Stone Age, Bronze Age, and Iron Age periods of human antiquity.

Simple technological advancements of paramount importance during the Stone Age included the ignition of fire by rubbing stones, the fabrication of numerous handmade weapons and utensils from stones, and clothing practice. To migrate from one area to another across the Ocean, a small group of Stone Age people created ocean-worthy outrigger canoe ship technology, which provided them with their first informal education in ocean currents, weather conditions, sailing practice, navigational, and star charts. Polished stone tools were manufactured from a range of hard rocks for agricultural use during the later Stone Age period (Neolithic period), mostly by digging underground tunnels, which can be regarded the initial steps in mining technology. The polished axes were so effective that they were still employed to clear forests and establish agricultural farming after bronze and iron appeared.

Although no written records exist for Stone Age nations, archaeological evidence shows that they transitioned from nomadic to agrarian existence. Ancient tools preserved in museums, cave paintings such as those found in Spain's Altamira Cave, and other prehistoric art such as the Venus of Windowsill, the Mother Goddess from Causeless, France, and other examples of prehistoric art include the Venus of Windowsill, the Mother Goddess from Causeless, France, and others.

With the development of agriculture, animal domestication, and the adoption of permanent settlements, the Neolithic Revolution of the Stone Age gave way to the Bronze Age. For these purposes, Bronze Age people developed metal smelting, using copper and eventually bronze, a tin-copper alloy, as their preferred materials.

Because iron utensils were stronger and cheaper than bronze ones, the Iron Age people substituted bronze and developed understanding of iron smelting technologies to cut the expense of living. The Iron Age was the last period before the creation of written scripts in many Eurasian societies.

During the age of Ancient Civilizations, educational technology was developed.

Educational technology dates back to the time when tribal priests systematized bodies of knowledge and ancient cultures devised pictographs or sign writing to record and transfer information, according to Paul Settler (2004). Every stage of human civilization has produced an instructional approach or collection of procedures aimed at implementing a specific culture, which has been backed up by a variety of studies and data. The more evolved the culture, the more complicated the instructional technology, which was created to mirror specific patterns of individual and group behavior in order to manage an educated society. Throughout history, any significant shift in educational beliefs, purposes, or objectives has resulted in a variety of instructional technology.

The Indus Valley Civilization was an early Bronze Age civilization that flourished in the Indian Subcontinent's northwest corner. The civilization flourished primarily in the Indus River basin and the Punjab region, extending up to the Haggard-Hakka River valley and the Ganges-Ramayana Dob (the majority of the civilization is now under Pakistan and the western states of modern-day India, with some parts extending up to southeastern Afghanistan and the easternmost part of Baluchistan, Iran).

The language spoken by the Happens has been the subject of long-running debate. It's considered that their writing was, at the very least, pictograph in nature. There were around 400 fundamental signs in the script, with many variations. People usually write their scripts in a right-to-left direction. The majority of the writing was discovered on seals and dealings, which were most likely utilized in trade as well as official and administrative duties.

Paper, early seismological detectors, toilet paper, matches, iron lough, the multi-tube seed drill, the suspension bridge, the wheelbarrow, the parachute, natural gas as a fuel, the magnetic compass, the raised-relief map, the blast furnace, the propeller, the crossbow, the South Pointing Chariot, and gun p With the invention of paper, they have taken the first step toward educational technology development by cultivating various handmade paper items as visual aids.

The ancient Egyptian language was once one of the world's oldest and most widely spoken languages. Their writing was made up of real-life images such as birds, animals, and various instruments. Hieroglyph is a term used to describe these images. Their language consisted of more than 500 hieroglyphs, also known as hieroglyphics. The existence of several varieties of creative hieroglyphics in ancient Egypt is evidenced by stone structures or tombs that were discovered and recovered later.

During the Medieval and Modern Periods, educational technology was developed.

The development of paper and the pulp paper making process in China in the early second century AD was transferred to the Middle East and expanded to the Mediterranean by Muslim conquests. A paper mill was also established in Sicily in the 12th century, according to evidence. The invention of the spinning wheel greatly boosted the productivity of the thread-making process, and when Lynn White combined it with an increase in the availability of rags, it resulted in the creation of inexpensive paper, which was a key factor in the development of printing technology.
