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.

Educational Educational TechnologyTechnology




“Technology is commonly thought of in terms of gadgets, instruments, machines and devices … most (educators) will defer to technology as computers.”

(Muffoletto, 1994)

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)




The invention of the printing press in the late 15th century gave rise to some of the first forms of mass communication, by enabling the publication of books and newspapers on a scale much larger than was previously possible. The invention also transformed the way the world received printed materials, although books remained too expensive really to be called a mass-medium for at least a century after that.





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.




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.





The 19th 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”.





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.





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.





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

What We’ve What We’ve LearnedLearned

Computer literacy or knowledge of computer applications is a moving target.

Teaching students technical skills for today is valuable.

More important are “learning to learn” tools for tomorrow and years to come.

17:20.0





Computer-based materials are just one component of resources available to educational system.

Integration of technology as a tool to advance learning in the content areas adds to the effectiveness of other resources and teacher created activities.

18:00.0





Development of technology materials and integration strategies is time intensive and should not be a classroom teacher’s primary responsibility – You’ve got enough to do!

18:20.0TEA





Educators must keep pace with technological advances.

But often times technology changes faster than the educational environment.

Business and Industry must do it’s part in providing economical technology solutions.

18:40.0





Teachers will always be necessary! Definition of learning environments

are changing. Identity of classrooms must

change.

19:03.0TEA




Our models of effective instruction must change too!

Educators must be more than: Sage on the Stage Guide on the Side


19:40.0





Vet in the Net

Today’s teacher must be willing to be: A participating learner in the classroom. One who will take the same risks and

not always have the right answer. A veteran learner in a network of

learners called the classroom.
