Educational Technology The history of educational technology is marked by the increasing complexity and sophistication of devices, exaggerated claims of effectiveness by technology advocates, sporadic implementation by classroom teachers, and little evidence that the technology employed has made a difference in student learning. Although technology proponents have from time to time claimed that technology will replace teachers, this has not occurred. The typical view among educators is that technology can be used effectively to supplement instruction by providing instructional variety, by helping to make abstract concepts concrete, and by stimulating interest among students.
