History of Educational Technology

There is no written evidence which can tell us exactly who has coined the phrase educational technology. Different educationists, scientists and philosophers at different time intervals have put forwarded different definitions of Educational Technology. Educational technology is a multifaceted and integrated process involving people, procedure, ideas, devices, and organization, where technology from different fields of science is borrowed as per the need and requirement of education for implementing, evaluating, and managing solutions to those problems involved in all aspects of human learning.

Educational technology, broadly speaking, has passed through five stages.

The first stage of educational technology is coupled with the use of aids like charts, maps, symbols, models, specimens and concrete materials. The term educational technology was used as synonyms to audio-visual aids.

The second stage of educational technology is associated with the ‘electronic revolution’ with the introduction and establishment of sophisticated hardware and software. Use of various audio-visual aids like projector, magic lanterns, tape-recorder, radio and television brought a revolutionary change in the educational scenario. Accordingly, educational technology concept was taken in terms of these sophisticated instruments and equipments for effective presentation of instructional materials.

The third stage of educational technology is linked with the development of mass media which in turn led to ‘communication revolution’ for instructional purposes. Computer-assisted Instruction (CAI) used for education since 1950s also became popular during this era.

The fourth stage of educational technology is discernible by the individualized process of instruction. The invention of programmed learning and programmed instruction provided a new dimension to educational technology. A system of self-learning based on self-instructional materials and teaching machines emerged.

The latest concept of educational technology is influenced by the concept 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. According to it, educational technology is a systematic way of designing, carrying out and evaluating the total process of teaching and learning in terms of specific objectives based on research.

Educational technology during the Stone Age, the Bronze Age, and the Iron Age

Educational technology, despite the uncertainty of the origin of the term, can be traced back to the time of the three-age system periodization of human prehistory; namely the Stone Age, the Bronze Age, and the Iron Age.

Duringthe Stone Age, ignition of fire by rubbing stones, manufacture of various handmade weapon and utensils from stones and clothing practice were some of the simple technological developments of utmost importance. A fraction of Stone Age people developed ocean-worthy outrigger canoe ship technology to migrate from one place to another across the Ocean, by which they developed their first informal education of knowledge of the ocean currents, weather conditions, sailing practice, astronavigation, and star maps. During the later Stone Age period (Neolithic period),for agricultural practice, polished stone tools were made from a variety of hard rocks largely by digging underground tunnels, which can be considered as the first steps in mining technology. The polished axes were so effective that even after appearance of bronze and iron; people used it for clearing forest and the establishment of crop farming.

Although Stone Age cultures left no written records, but archaeological evidences proved their shift from nomadic life to agricultural settlement. Ancient tools conserved in different museums, cave paintings like Altamira Cave in Spain, and other prehistoric art, such as the Venus of Willendorf, Mother Goddess from Laussel, France etc. are some of the evidences in favour of their cultures.

Neolithic Revolution of Stone Age resulted into the appearance of Bronze Age with development of agriculture, animal domestication, and the adoption of permanent settlements. For these practices Bronze Age people further developed metal smelting, with copper and later bronze, an alloy of tin and copper, being the materials of their choice.

The Iron Age people replaced bronze and developed the knowledge of iron smelting technology to lower the cost of living since iron utensils were stronger and cheaper than bronze equivalents. In many Eurasian cultures, the Iron Age was the last period before the development of written scripts.

Educational technology during the period of Ancient civilizations

According to Paul Saettler, 2004, Educational technology can be traced back to the time when tribal priests systematized bodies of knowledge and ancient cultures invented pictographs or sign writing to record and transmit information. In every stage of human civilization, one can find an instructional technique or set of procedures intended to implement a particular culture which were also supported by number of investigations and evidences. The more advanced the culture, the more complex became the technology of instruction designed to reflect particular ways of individual and social behaviour intended to run an educated society. Over centuries, each significant shift in educational values, goals or objectives led to diverse technologies of instruction.

The greatest advances in technology and engineering came with the rise of the ancient civilizations. These advances stimulated and educated other societies in the world to adopt new ways of living and governance.

The Indus Valley Civilization was an early Bronze Age civilization which was located in the northwestern region of the Indian Subcontinent. The civilization was primarily flourished around the Indus River basin of the Indus and the Punjab region, extending upto the Ghaggar-Hakra River valley and the Ganges-Yamuna Doab, (most of the part is under today’s Pakistan and the western states of modern-day India as well as some part of the civilization extending upto southeastern Afghanistan, and the easternmost part of Balochistan, Iran).

There is a long term controversy to be sure about the language that the Harappan people spoke. It is assumed that their writing was at least seems to be or a pictographic script. The script appears to have had about 400 basic signs, with lots of variations. People write their script with the direction generally from right to left. Most of the writing was found on seals and sealings which were probably used in trade and official & administrative work.

Harappan people had the knowledge of the measuring tools of length, mass, and time. They were the first in the world to develop a system of uniform weights and measures.

In a study carried out by P. N. Rao et al. in 2009, published in Science, computer scientists found that the Indus script’s pattern is closer to that of spoken words, which supported the proposed hypothesis that it codes for an as-yet-unknown language.

According to the Chinese Civilization, some of the major techno-offerings from China include paper, early seismological detectors, toilet paper, matches, iron plough, the multi-tube seed drill, the suspension bridge, the wheelbarrow, the parachute, natural gas as fuel, the magnetic compass, the raised-relief map, the blast furnace, the propeller, the crossbow, the South Pointing Chariot, and gun powder. With the invent of paper they have given their first step towards developments of educational technology by further culturing different handmade products of paper as means of visual aids.

Ancient Egyptian language was at one point one of the longest surviving and used languages in the world. Their script was made up of pictures of the real things like birds, animals, different tools, etc. These pictures are popularly called hieroglyph. Their language was made up of above 500 hieroglyphs which are known as hieroglyphics. On the stone monuments or tombs which were discovered and rescued latter on provides the evidence of existence of many forms of artistic hieroglyphics in ancient Egypt.

Educational technology during Medieval and Modern Period

Paper and the pulp papermaking process which was developed in China during the early 2nd century AD, was carried to the Middle East and was spread to Mediterranean by the Muslim conquests. Evidences support that a paper mill was also established in Sicily in the 12th century. The discovery of spinning wheel increased the productivity of thread making process to a great extent and when Lynn White added the spinning wheel with increasing supply of rags, this led to the production of cheap paper, which was a prime factor in the development of printing technology.

The invention of the printing press was taken place in approximately 1450 AD, by Johannes Gutenburg, a German inventor. The invention of printing press was a prime developmental factor in the history of educational technology to convey the instruction as per the need of the complex and advanced-technology cultured society.

In the pre-industrial phases, while industry was simply the handwork at artisan level, the instructional processes were relied heavily upon simple things like the slate, the horn book, the blackboard, and chalk. It was limited to a single text book with a few illustrations. Educational technology was considered synonymous to simple aids like charts and pictures.

The year 1873 may be considered a landmark in the early history of technology of education or audio-visual education. An exhibition was held in Vienna at international level in which an American school won the admiration of the educators for the exhibition of maps, charts, textbooks and other equipments.

Maria Montessori (1870-1952), internationally renowned child educator and the originator of Montessori Method exerted a dynamic impact on educational technology through her development of graded materials designed to provide for the proper sequencing of subject matter for each individual learner. Modern educational technology suggests many extension of Montessori’s idea of prepared child centered environment.

In1833, Charles Babbage’s design of a general purpose computing device laid the foundation of the modern computer and in 1943, the first computing machine as per hi design was constructed by International Business Machines Corporation in USA. The Computer Assisted instruction (CAI) in which the computer functions essentially as a tutor as well as the Talking Type writer was developed by O.K. Moore in 1966. Since 1974, computers are interestingly used in education in schools, colleges and universities.

In the beginning of the 19th century, there were noteworthy changes in the field of education. British Broadcasting Corporation (BBC), right from its start of school broadcasts in 1920 had maintained rapid pace in making sound contribution to formal education. In the USA, by 1952, 20 states had the provision for educational broadcasting. Parallel to this time about 98% of the schools in United Kingdom were equipped with radios and there were regular daily programmes.

Sidney L. Pressey, a psychologist of Ohio state university developed a self-teaching machine called ‘Drum Tutor’ in 1920. Professor Skinner, however, in his famous article ‘Science of Learning and art of Teaching’ published in 1945 pleaded for the application of the knowledge derived from behavioral psychology to classroom procedures and suggested automated teaching devices as means of doing so.

Although the first practical use of Regular television broadcasts was in Germany in 1929 and in 1936 the Olympic Games in Berlin were broadcasted through television stations in Berlin, Open circuit television began to be used primarily for broadcasting programmes for entertainment in 1950. Since 1960, television is used for educational purposes.

In 1950, Brynmor, in England, used educational technological steps for the first time. It is to be cared that in 1960, as a result of industrial revolution in America and Russia, other countries also started progressing in the filed of educational technology. In this way, the beginning of educational technology took place in 1960 from America and Russia and now it has reached England, Europe and India.

During the time of around 1950s, new technocracy was turning it attraction to educations when there was a steep shortage of teachers in America and therefore an urgent need of educational technology was felt. Dr. Alvin C. Eurich and a little later his associate, Dr. Alexander J. Stoddard introduced mass production technology in America.

Team teaching had its origin in America in the mid of 1950’s and was first started in the year 1955 at Harvard University as a part of internship plan.

In the year 1956, Benjamin Bloom from USA introduced the taxonomy of educational objectives through his publication, “The Taxonomy of Educational Objectives, The Classification of Educational Goals, Handbook I: Cognitive Domain”.

In 1961, Micro teaching technique was first adopted by Dwight W. Allen and his co-workers at Stanford University in USA.

Electronics is the main technology being developed in the beginning of 21st century. Broadband Internet access became popular and occupied almost all the important offices and educational places and even in common places in developed countries with the advantage of connecting home computers with music libraries and mobile phones.

Today’s classroom is more likely to be a technology lab, a room with rows of students using internet connected or Wi-Fi enabled laptops, palmtops, notepad, or perhaps students are attending a video conferencing or virtual classroom or may have been listening to a podcast or taking in a video lecture. Rapid technological changes in the field of educational have created new ways to teach and to learn. Technological changes also motivated the teachers to access a variety of information on a global scale via the Internet, to enhance their lessons as well as to make them competent professional in their area of concern. At the same time, students can utilize vast resources of the Internet to enrich their learning experience to cope up with changing trend of the society. Now a days students as well teachers are attending seminars, conferences, workshops at national and international level by using the multimedia techno-resources like PowerPoint and even they pursue a variety of important courses of their choice in distance mode via online learning ways. Online learning facility has opened infinite number of doors of opportunities for today’s learner to make their life happier than ever before.

Sufficient Impacts on the History of Special Education

Special Education, over the years, has grown and improved substantially. The history of it contains many admirable historical figures and events that have defined and impacted Special Education. I, however, picked 4 people and one event that I thought had a great impact on Special education. Without these people, special education would not be where it is today. I believe Jean Itard, Edouard Seguin, Helen Keller, Samuel Howe and the Brown Vs. Board of Education, were all important highlights in the history of Special Ed. Although they are not the only ones that should be commended for doing an outstanding job in improving the status of Special Ed, education would not progress as much without them.

Jean Itard is perhaps best defined as “the Father of Special Education” Although he was not aware that his work would have been defined as Special education, his work had a profound effect on future generations. Itard was educated to be a tradesman. However, during the French Revolution, he joined the army to become an assistant surgeon. After the war, he took upon a new and challenging project called Victor. Victor was a wild, animal- like boy that was found running around in the forest. In 1800 he was bought to Paris for observation. When Itard saw the wild, uncivilized boy, he assumed that he had been recently abandoned by his parents. Like a wild animal that does not like to be caged, Victor escaped a couple of times from a widow’s bedroom window. He was normally deficient, but Itard believed he could educate the boy through experience. During Itard’s time, it was a common belief that mentally disabled people were uneducable. The remarkable guru spent five years trying to “cure” him. After 5 years, Victor could read and speak a few words, and could also show affection towards his caretakers. Unfortunately, he never reached normality. Itard thought he had failed as a teacher, but his experience with Victor taught others that in order to achieve the smallest success, he had to accept Victor as a person. His work implemented the most important truth of all, and that was that education had to be in harmony with the dynamic nature of life. 

The next important historical figure was not a teacher, but a remarkable student. Helen Keller had an illness which left her blind and deaf. As a young child, she suffered through severe retardation. She made animal like sounds, ripped her clothes off, and was not toilet trained. It was apparent that she lacked civilized traits. Many years later, even she said “I was an animal.” Poor Helen had become a very difficult child. She terrorized the house hold, and often endangered the people in it. The Kellers were advised to visit an expert on deaf children. This was the well known Alexander Graham Bell. Bell suggested that the family seek an instructor from Perkins University.

On March 3rd, 1883, she met her teacher and caretaker, Miss Anne Sullivan. During the first meeting of theirs, Anne spelled out the word d-o-l-l on her arm. After writing the word on her arm, Anne gave Helen a doll, to show her what “doll” was. The next word she was spelled out was “cake” Although she could quickly repeat the same finger movements, Helen never really understood what the words meant. While Anne was struggling to help her understand the meaning of a word, she also was struggling to try to control Helen’s undesirable behavior. Making her educated and civilized was a great challenge for Anne. After a month, her behavior did improve. It was that initial month that the bond between Anne and Helen was established. After that month was the time that people referred to as the “miracle. It was not until 1887, that Helen began to grasp an understanding of the words. Anne pumped water on to Helen’s hand, and spelled out the word on her hand. Something about this activity helped Helen understand the meaning of the words.. Helen progressed as an individual over the years.

The life that she lived has had an impact on teaching methods, as well as technology. With the aid of Anne, through her writing, lectures, and the way she lived life, she has shown people that being disabled is not the end of the world. Her impact on education can be shown through this quote of hers: “The public must learn that the blind man is neither genus nor a freak nor an idiot. He has a mind that can be educated, a hand which can be trained…”

The Truth About Our Physical Education History

Remember high school gym class? You played volleyball, ran a mile on the track, and ducked before being hit in the face during a vigorous game of dodge ball? Physical education has been part of the educational scene for nearly 200 years. It is vital that students participate in physical education to keep their mind and body in peak learning condition. Currently, the childhood obesity rate is dangerously climbing to epidemic levels. Therefore, the focus on physical education is more important then ever before.

The question is how should physical education be conducted? First, take a look at physical education history. Physical education has evolved over the years. Physical education is defined as “instruction in the development and care of the body ranging from simple calisthenics exercises to a course of study providing training in hygiene, gymnastics, and the performance and management of athletic games (Merriam-Webster Dictionary).” This definition is broad because you can learn several topics ranging from the rules of basketball to sex education. It depends on the school policies of your state educational system.

Physical education was officially recognized in the United States in the early 1800’s. Colleges and Universities began to offer physical education programs throughout the 1800’s. Finally, in 1866 California was the first to mandate physical education. Many states followed this mandate within the next 30 years. The importance of training the body as well as the mind became prevalent in the educational system.

The 20th century brought varying levels of physical education to each state. Presidents such as Eisenhower and Kennedy promoted physical education and fitness. Children took the Presidential Fitness test each year to assess their physical fitness level. This arose from the need for U.S. students to be as physical fit as their European counterparts.

Controversial issues have played an integral role in physical education history. For example, in 1972 Title IX banned sexual discrimination in schools regarding sports and academics. This allowed female athletes to actively participate in team sports other than cheerleading with the financial and emotional support of the school system.

Another controversial issue is sexual education. It has been the subject of intense debate for many decades. Each state has specific guidelines about what will be taught and whether students can opt out of the sexual education program. Some states allow students to watch a video of a child being born while other states only discuss abstinence.

The official employment of physical education programs has a 200 year history which has become home to controversial issues, social reform, and overall child well being. Physical education will continue to evolve as the needs of the student population changes, societal attitudes fluctuate, and the flow of educational funds towards physical education is maintained.
