Technology
Technically speaking, anything that man has created or modified for his use is considered to be technology, which includes physical objects, their application, ideas, and even new systems of behavior. Educational technology includes every related device, method, system and theory applied to instruction. Technology spans a vast territory, from simple pencil and paper used in a classroom, through to computers, the Internet, and systems of evaluation, planning, production, scheduling, and sequencing, instructional activities, assessments, grading scales and curves, to name just a few. Teaching proper selection and hunting of animals through paintings on cave walls may have been one of the first visible examples of human instruction. Later, much more sophisticated devices came on the scene to enable mass education, in much more efficient ways. Now, we can barely envision a world without instant communications and vast numbers of messages being exchanged, even while we walk, or drive, or sit or sleep. Multimedia devices seem to surround us, and even invade our quiet times, and off hours.
