Drawings on Cave Walls
In some ways, educational technology may be traced back to the birth of very early tools, such as cave paintings. -
2700 BCE
Sumerian Abacus
Between 2700 and 2300 BC, the Sumerian abacus appeared. It had a table of sequential columns that demarcated the sexagesimal number system's successive orders of magnitude. -

Writing Slates
The writing slate's actual origins are unknown. It was first mentioned in the fourteenth century, and evidence suggests it was also utilized in the sixteenth and seventeenth centuries. -
Blackboard
When James Pillans, headmaster and geography teacher at the Old High School in Edinburgh, Scotland, hung a huge piece of slate on the classroom wall, he is credited with developing the first modern blackboard. -
Mimeograph
A mimeograph machine is a low-cost duplicating machine that works by squeezing ink into paper through a stencil. Albert Blake Dick invented the term mimeograph when he acquired Edison's inventions in 1887. -
Spirit Duplicator
Wilhelm Ritzerfeld designed the spirit duplicator in 1923, and it was widely used throughout the rest of the twentieth century. The machine coexisted with the mimeograph. -
Radio
In the 1920s, the British Broadcasting Corporation (BBC) began airing instructional radio programs for schools. Insects in Relation to Man was the first adult education radio broadcast from the BBC, which aired in 1924. -
Television
The first instructional television shows for open transmission were established in the 1950s. The City Colleges of Chicago were the first to broadcast large-scale instructional television programs in 1951. -
Teaching Machine
In 1954, based on the principle of behaviorism, B.F. Skinner began experimenting with teaching machines that used programmed learning. One of the first examples of computer-based learning was Skinner's teaching machines. -
Photocopier
A photocopier is a machine that replicates documents and other visual images quickly and inexpensively onto paper or plastic film. In 1938, inventor Chester Carlson made the first replica using static electricity created with a handkerchief, light, and dry powder. More than 20 years later, in 1959, the copier finally hit the market. -
Handheld Calculator
The first handheld calculator was a 1967 prototype known as "Cal Tech," which was developed by Texas Instruments' Jack Kilby as part of a research initiative to build a portable calculator. Its output device was a paper tape, and it could add, multiply, subtract, and divide. -
Computer
By the early 1980s, computer-assisted education had acquired widespread acceptability in schools. Drilling and practice programs for use in the classroom were initially developed during this time period. -
Internet
The Internet's birthday is celebrated on January 1, 1983. Previously, there was no standard means for different computer networks to connect with one another. It created vast and endless opportunities to reach information easily. -
Social Media
The National Science Foundation launched the NSFNET, a more robust, nationwide digital network, in 1987, which served as a direct forerunner to today's internet. The first true social media network was developed a decade later, in 1997. Blogs, wikis, YouTube videos, mobile devices such as phones and tablets, Twitter, Skype, and Facebook are all examples of social media technology. -
Video Conference
The development of video compression technology and relatively low cost video servers in the early 2000s led to the introduction of lecture capture systems for recording and streaming classroom lectures in 2008. -
