The use of technology in the classroom is as old as the notion of classroom itself. It is true that the actual mainstream definition of technology is shaped by those major technological breakthroughs that marked the last century particularly since the invention of radio, TV, and PCs. Technology could also be traced back to the invention of the printing machine by Gutenburg in the 15th century. However, technology in its basic form is information on anything that man makes for his benefit out of resources available, in order to make tasks simpler to perform (stone tools, fire, wheel etc).
Trying to trace back the evolutionary process of the use of technology in the classroom, I came across a wonderful resource from New York Times in which they provided a graphic history of classroom technology, from the writing slate to the electronic tablet.
