Educational technology, speaking broadly, has exceeded through five levels.
The first level of educational technology is in conjunction with the utilization of helps like graphs, maps, icons, models, specimens and concrete materials. The word educational technology was used as synonyms to audio-visual assists.
The second level of educational technology is from the 'electronic trend' with the advantages and establishment of superior hardware and software. Usage of various audio-visual products like projector, powerful lanterns, tape-recorder, television and radio brought a revolutionary change in the educational scenario. Accordingly, educational technology concept was taken in conditions of these superior instruments and equipments for effective presentation of instructional materials.
The third level of educational technology is associated with the introduction of mass media which resulted in 'communication trend' for instructional purposes. Computer-assisted Teaching (CAI) used for education since 1950s also became popular in this era.
The fourth level of educational technology is discernible by the individualized procedure for instruction. The technology of programmed learning and designed instruction provided a fresh dimensions to educational technology. Something of self-learning predicated on self-instructional materials and coaching machines surfaced.
The latest idea of educational technology is inspired by the idea of system anatomist or system methodology which targets language laboratories, educating machines, programmed education, multimedia systems and the utilization of the computer in training. Matching to it, educational technology is a organized way of planning, undertaking and evaluating the full total process of coaching and learning in conditions of specific targets predicated on research.
Educational technology through the Stone Time, the Bronze Years, and the Flat iron Age
Educational technology, regardless of the uncertainty of the foundation of the word, can be followed back again to enough time of the three-age system periodization of real human prehistory; the Stone Age namely, the Bronze Age, and the Iron Age.
Duringthe Stone Time, ignition of hearth by rubbing rocks, manufacture of varied handmade tool and items from rocks and clothing practice were a few of the simple technical developments very important. A portion of Stone Get older people developed ocean-worthy outrigger canoe dispatch technology to migrate in one destination to another over the Ocean, where they developed their first casual education of understanding of the sea currents, climate, sailing practice, astronavigation, and star maps. Through the later Stone Get older period (Neolithic period),for agricultural practice, refined natural stone tools were created from a number of hard rocks typically by digging underground tunnels, that can be regarded as the first steps in mining technology. The refined axes were so effective that after appearance of bronze and flat iron even; people used it for clearing forest and the establishment of crop farming.
Although Stone Get older cultures still left no written information, but archaeological evidences proven their transfer from nomadic life to agricultural negotiation. Old tools conserved in several museums, cave paintings like Altamira Cave in Spain, and other prehistoric art work, including the Venus of Willendorf, Mom Goddess from Laussel, France etc. are a few of the evidences towards their cultures.
Neolithic Trend of Stone Years resulted in to the appearance of Bronze Age group with development of agriculture, pet animal domestication, and the adoption of everlasting settlements. For these routines Bronze Time people further developed steel smelting, with copper and later bronze, an alloy of copper and tin, being the materials of the choice.
The Iron Years people changed bronze and developed the data of flat iron smelting technology to lessen the expense of living since flat iron utensils were more robust and cheaper than bronze equivalents. In lots of Eurasian civilizations, the Iron Years was the previous period prior to the development of written scripts.
Educational technology over Ancient civilizations
Regarding to Paul Saettler, 2004, Educational technology can be followed back to enough time when tribal priests systematized systems of knowledge and traditional cultures created pictographs or indication writing to record and transmit information. Atlanta divorce attorneys stage of individual civilization, one will discover an instructional approach or group of procedures designed to implement a specific culture that have been also recognized by amount of investigations and evidences. The more complex the culture, the more technical became the technology of training designed to indicate particular means of individual and interpersonal behaviour designed to run an informed society. Over ages, each significant switch in educational ideals, goals or goals resulted in diverse systems of teaching.
The best improvements in technology and anatomist was included with the go up of the historical civilizations. These advances stimulated and educated other societies on earth to look at new means of living and governance.
The Indus Valley Civilization was an early on Bronze Get older civilization that was found in the northwestern region of the Indian Subcontinent. The civilization was generally flourished about the Indus River basin of the Indus and the Punjab region, stretching upto the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab, (a lot of the part is under today's Pakistan and the european says of modern-day India as well as some area of the civilization increasing upto southeastern Afghanistan, and the easternmost part of Balochistan, Iran).
There's a permanent controversy to be certain about the vocabulary that the Harappan people spoke. The assumption is that their writing was at least appears to be or a pictographic script. The script seems to have acquired about 400 basic indicators, with plenty of variations. People write their script with the course from to still left generally. A lot of the writing was entirely on seals and sealings that have been probably found in trade and official & administrative work.
