The history of educational technology can be traced back to ancient cultures that developed systems of knowledge and invented writing to record and transmit information. In ancient Greece, the term "techne" referred to the systematic application of knowledge to instruction. Major contributors in the 19th century included Edward Thorndike, who formulated the scientific theory of learning, and John Dewey, who introduced the scientific method to instruction. The 19th century also saw effective technological developments like textbooks, blackboards, and improved writing tools. Visual instruction became popularized through photography's invention. Instructional television and early computers were developed throughout the 20th century, leading to the internet revolution of the 1990s.
