There are no written records that can tell us who created the concept of technology education. Some teachers have scientists and philosophers at various time intervals before a different definition of educational technology. Technology education is a complex and integrated people, processes, ideas, equipment and facilities that have been borrowed technology in various fields of science with the needs and training requirements for implementation, evaluation and management solutions to this problem in all fields of human learning is involved.
Educational technology in general has gone through five stages.
The first phase of educational technology for the use of tools such as diagrams, maps, symbols, templates, models and concrete materials are combined. Technology education is a term synonymous with audio-visual use.
The second stage of educational technology associated with the “electronic revolution” with the introduction and implementation of hardware and advanced software. The use of different audio-visual aids such as projectors, tape recorders magic lantern, radio and television, a revolutionary change in the educational scenario. Thus, the concept of educational technology in challenging instruments and apparatus for the effective presentation of educational materials is assumed.
The third stage of educational technology with the development of mass media, which in turn leads to the “communications revolution” associated with educational purposes. Assisted Instruction (CAI) has been used since 1950 to train people in this time.
The fourth stage of educational technology can be seen through the lessons. Discovery learning and programmed instruction can be programmed to provide a new dimension to educational technology. An independent study based on self-learning and teaching materials appear machines.
Finally the concept of educational technology through the concept of systems engineering or systems approach to language laboratories, teaching machines, programmed instruction, multimedia technology and computer use in the classroom influenced concentrated. After education in a systematic technology for implementation, design and evaluation based on the entire process of learning to the specific objectives of the study.
Technology education in the Stone Age, Bronze Age and Iron Age
Educational technology, despite the uncertainty about the origin of the term, can be associated with periods of three years of human history, namely the Stone Age, Bronze Age and Iron Age.
Duringthe the Stone Age, the fire by rubbing stones, handmade stone weapons and tools and equipment from the practice range is a bit of simple technology development is very important. A fraction of the Stone Age technology developed marine boat boat to travel from one place to another at sea, where they migrated first to develop their knowledge of formal education on ocean currents, weather conditions, sailing, celestial navigation and charts. During the last period of the Neolithic Age (Neolithic), tools, agricultural practices of different stones polished stones that are difficult, especially by digging underground tunnels, which can be considered as a first step in mining engineering. Polished axes so effective that even after the appearance of bronze and iron, people use to clean the forests and the establishment of agricultural crops.
Although the Stone Age cultures left no written records, but archaeological evidence of transition from nomadic to agricultural settlements. Old tools that are stored in various museums, such as the Altamira cave paintings in Spain and other prehistoric rock art, such as the Willendorf Venus, the mother goddess Laussel, France, etc. is some evidence that supports their culture.
Neolithic Revolution led to the emergence of the Stone Age to the Bronze Age to the development of agriculture, domestication of animals, and adoption of a permanent settlement. For this practice developed Bronze Age smelting, copper and bronze, an alloy of tin and copper, the theme of their choice.
Iron replaced bronze age people and knowledge in the field of steel technology to reduce the cost of living with iron tools more powerful and less expensive than equivalent bronze. In many Iron Age cultures of Eurasia, the last time before the development of scripts written.
