  • 1. HISTORY OF EDUCATIONAL TECHNOLOGY Where Are We Going & Where Have We Been Prepared & Modified by FOR-IAN V. SANDOVAL Lesson 1
  • 2. Educational Technology
    • Objectives:
    • To identify events and devices of the past that contributed to the technological revolution.
    • To examine the organizations and their viewpoints that have shaped technology use in the classroom today.
    • To prepare for the future in educational technology by analyzing current trends and advances.
  • 3. Educational Technology
    • “ Technology is commonly thought of in terms of gadgets, instruments, machines and devices … most (educators) will defer to technology as computers.”
    • (Muffoletto, 1994)
    TEA
  • 4. Educational Technology
    • The history of “Educational technology … can be traced back to the time when tribal priests systemized bodies of knowledge, and early cultures invented pictographs or sign writing to record and transmit information.”
    • (Paul Saettler, 1990)
  • 5. Educational Technology In ancient Greece, the Elder Sophist used the term “techne” to refer the process of applying knowledge systematically to the practical art of instruction. They formulated cognitive rules, systematically analyzed subject matter designed instructional technologies and devised effective instructional materials.
  • 6. Educational Technology During the Middle Age Advent of Scholastic Philosophy, Pierre Abelard introduced a technology of instruction which was really a new method of structuring and presenting materials that helped set the style of scholastic education.
  • 7. Educational Technology Comenius, Pestalozzi, Froebel, Herbart and Montessori contributed their own concept on educational technology improving educative process . John Amos Comenius was recognized as the pioneer of modern instructional technology by reason of his book Orbis Pictus (The World in Picture) which was illustrated textbooks for children studying Latin & Sciences.
  • 8. Educational Technology Edward Thorndike and John Dewey formulated scientific theory of learning and the scientific method, respectively. Thorndike gave emphasis to the use of empirical investigation as a basis for an organized process of learning. On his part, Dewey introduced a method of instruction in terms scientific method in broad terms
  • 9. The 19 th century paved in the advent of effective technological development including the production of textbooks, use of blackboards and improvements in writing implements like pen and ink. Photography was invented, giving a way to a movement called “ Visual Instruction ”. Educational Technology
  • 10. By 1920, visual media became widely accepted. Then came the publication of audio-visual media texts. In 1926, educational films were used as instructional media. In 1927, Pressey wrote on programmed learning through a machine which tested and confirmed a learning task. Educational Technology
  • 11. In 1932, the first instructional television program was aired at the State University of Iowa. About the same time, the 16 mm sound motion picture was developed and this served as the educational workhorse during the audio-visual movement of the time. Educational Technology
  • 12. During World War II, the U.S. government encouraged the implementation of technology of instruction for military training programs. This gave impetus to a system approach to instruction to include: micro-teaching, individualized instruction, Language laboratories, behavioral laboratories, behavioral objectives, computer assisted instruction and among others Educational Technology
