There’s no written evidence which could inform us just who has created the saying educational technology. Different educationists, scientists and philosophers at different time times have put forwarded different definitions of Educational Technology. Educational technologies are a multifaceted and integrated process involving people, procedure, ideas, devices, and organization, where technology from various fields of science is lent as reported by the need and dependence on education for applying, evaluating, and managing methods to individuals problems involved with every aspect of human learning.
Educational technology, generally speaking, has transpired through five stages.
The very first stage of educational technologies are coupled by using aids like charts, maps, symbols, models, examples and concrete materials. The word educational technology was utilized as synonyms to audio-powerpoints.
The 2nd stage of educational technologies are connected using the ‘electronic revolution’ using the introduction and establishment of sophisticated software and hardware. Utilization of various audio-powerpoints like projector, magic lanterns, tape-recorder, tv and radio introduced an innovative alternation in the academic scenario. Accordingly, educational technology concept was taken when it comes to these sophisticated instruments and equipments for effective presentation of instructional materials.
The 3rd stage of educational technologies are associated with the introduction of media which brought to ‘communication revolution’ for instructional purposes. Computer-aided Instruction (CAI) employed for education since 1950s also grew to become popular in this era.
The 4th stage of educational technologies are discernible through the individualized procedure for instruction. The invention of programmed learning and programmed instruction provided a brand new dimension to educational technology. A method of self-learning according to self-instructional materials and teaching machines emerged.
The most recent idea of educational technologies are affected by the idea of system engineering or system approach which concentrates on language laboratories, teaching machines, programmed instruction, multimedia technologies and using the pc in instruction. Based on it, educational technologies are an organized method of designing, transporting out and evaluating the entire procedure for learning and teaching when it comes to specific objectives according to research.
Educational technology throughout the Stone Age, the Bronze Age, and also the Iron Age
Educational technology, regardless of the uncertainty from the origin from the term, could be tracked to time from the three-age system periodization of human prehistory namely the Stone Age, the Bronze Age, and also the Iron Age.
Duringthe Stone Age, ignition of fireside by rubbing gemstones, output of various hand crafted weapon and utensils from gemstones and clothing practice were a few of the simple technological developments very important. A small fraction of Stone Age people developed sea-worthy outrigger canoe ship technology emigrate in one spot to another over the Sea, through which they developed their first informal education of understanding from the sea currents, climate conditions, sailing practice, astronavigation, and star maps. Throughout the later Stone Age period (Neolithic period),for farming practice, polished stone tools were created from a number of hard rocks usually by digging subterranean tunnels, which may be regarded as the very first stages in mining technology. The polished axes were work that despite appearance of bronze and iron people tried on the extender for clearing forest and also the establishment of crop farming.
