History of Educational Technology

1. The History of Educational Technology

2. It’s amazing how quickly technology changes, even in the course of six months. But can you imagine how much it has changed over decades? The Timeline of Educational Technology in Schools Infographic shows how educational technology has evolved in schools over the past 114 years.

3. Educational Technology Timeline 1650 The Horn Book Wooden paddles with printed lessons were popular in the colonial era. On the paper there was usually the alphabet and a religious verse which children would copy to help them learn how to write.

4. Educational Technology Timeline 1870 The Magic Lantern The precursor to a slide projector, the ‘magic lantern’ projected images printed on glass plates and showed them in darkened rooms to students. By the end of World War I, Chicago’s public school system had roughly 8,000 lantern slides.

5. Educational Technology Timeline 1890 School Slate Used throughout the 19th century in nearly all classrooms, a Boston school superintendent in 1870 described the slate as being “if the result of the work should, at any time, be found infelicitous, a sponge will readily banish from the slate all disheartening recollections, and leave it free for new attempts."

6. Educational Technology Timeline 1890 Chalkboard Still going strong to this day, the chalkboard is one of the biggest inventions in terms of educational technology.

7. Educational Technology Timeline 1900 The Pencil Just like the chalkboard, the pencil is also found in basically all classrooms in the U.S. In the late 19th century, mass-produced paper and pencils became more readily available and pencils eventually replaced the school slate.

8. Educational Technology Timeline 1905 Stereoscope At the turn of the century, the Keystone View Company began to market stereoscopes which are basically three-dimensional viewing tools that were popular in homes as a source of entertainment. Keystone View Company marketed these stereoscopes to schools and created hundreds of images that were meant to be used to illustrate points made during lectures.

9. Educational Technology Timeline 1925 Film Projector Similar to the motion-picture projector, Thomas Edison predicted that, thanks to the invention of projected images, “books will soon be obsolete in schools. Scholars will soon be instructed through the eye.”

10. Educational Technology Timeline 1925 Radio New York City’s Board of Education was actually the first organization to send lessons to schools through a radio station. Over the next couple of decades, “schools of the air” began broadcasting programs to millions of American students.

11. Educational Technology Timeline 1930 Overhead Projector Initially used by the U.S. military for training purposes in World War II, overhead projectors quickly spread to schools and other organizations around the country.

12. Educational Technology Timeline 1940 Ballpoint Pen While it was originally invented in 1888, it was not until 1940 that the ballpoint pen started to gain worldwide recognition as being a useful tool in the classroom and life in general. The first ballpoint pens went on sale at Gimbels department store in New York City on 29 October 1945 for US$9.75 each.

13. Educational Technology Timeline 1940 Mimeograph Surviving into the Xerox age, the mimeograph made copies by being hand-cranked. Makes you appreciate your current copier at least a little bit now.

14. Educational Technology Timeline 1950 Headphones Thanks to theories that students could learn lessons through repeated drills and repetition (and repeated repetition) schools began to install listening stations that used headphones and audio tapes. Most were used in what were dubbed ‘language labs’ and this practice is still in use today, except now computers are used instead of audio tapes.

15. Educational Technology Timeline 1950 Slide Rule William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier. Before the advent of the pocket calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced; but around 1974 the electronic scientific calculator made it largely obsolete and most suppliers left the business.

16. Educational Technology Timeline 1951 Videotapes The electronics division of entertainer Bing Crosby’s production company, Bing Crosby Enterprises (BCE), gave the world’s first demonstration of a videotape recording in Los Angeles on November 11, 1951. Developed by John T. Mullin and Wayne R. Johnson since 1950, the device gave what were described as “blurred and indistinct” images, using a modified Ampex 200 tape recorder and standard quarter-inch audio tape moving at 360 inches per second.

17. Educational Technology Timeline 1958 Educational Television By the early sixties, there were more than 50 channels of TV which included educational programming that aired across the country.

18. Educational Technology Timeline 1970 Hand-held Calculator The predecessor of the much-loved and much-used TI-83, this calculator paved the way for the calculators used today. There were initial concerns however as teachers were slow to adopt them for fear they would undermine the learning of basic skills.

19. Educational Technology Timeline 1972 Scantron The Scantron Corporation removed the need for grading multiple-choice exams. The Scantron machines were free to use but the company made money by charging for their proprietary grading forms.

20. Educational Technology Timeline 1980 Plato Computer Public schools in the U.S. averaged about one computer for every 92 students in 1984. The Plato was one of the most-used early computers to gain a foothold in the education market. Currently, there is about one computer for every 4 students.

21. Educational Technology Timeline 1985 CD-ROM Drive A single CD could store an entire encyclopedia plus video and audio. The CD-ROM and eventually the CD-RW paved the way for flash drives and easy personal storage.

22. Educational Technology Timeline 1985 Hand-held Graphing Calculator The successor to the hand-held calculator, the graphing calculator made far more advanced math much easier as it let you plot out points, do long equations, and play ‘Snake’ as a game when you got bored in class.

23. Educational Technology Timeline 1999 Interactive Whiteboard The chalkboard got a facelift with the whiteboard. That got turned into a more interactive system that uses a touch-sensitive white screen, a projector, and a computer. Still getting slowly rolled out to classrooms right now.

24. Educational Technology Timeline 2005 iClicker There are many similar tools available now, but iClicker was one of the first to allow teachers to be able to quickly poll students and get results in real time.

25. Educational Technology Timeline 2006 XO Laptop The ‘One Laptop Per Child’ computer was built so it was durable and cheap enough to sell or donate to developing countries. It’s an incredible machine that works well in sunlight, is waterproof, and much more.

26. 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.

27. Educational Technology Timeline 2010 Apple iPad Just like the original school slate, could the iPad bring Thomas Edison’s statement to life? Could the iPad make it so “scholars will soon be instructed through the eye.” Only time will tell.
