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)

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)

what we ve learned
What We’ve Learned
  • 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.


what we ve learned49
What We’ve Learned
  • 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.


what we ve learned50
What We’ve Learned

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!



what we ve learned51
What We’ve Learned
  • 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.


what we ve learned52
What We’ve Learned
  • Teachers will always be necessary!
  • Definition of learning environments are changing.
  • Identity of classrooms must change.



what we ve learned53
What We’ve Learned
  • Our models of effective instruction must change too!
  • Educators must be more than:
    • Sage on the Stage
    • Guide on the Side


what we ve learned54
What We’ve Learned

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.
