The term educational technology refers to the use of technology in educational settings, whether it be elementary and secondary schools, colleges and universities, corporate training sites, or independent study at home. This discussion, however, will focus on educational technology in grades K—12.   Educational technology has both general and specialized meanings. To the lay public and to a majority of educators, the term refers to the instructional use of computers, television, and other kinds of electronic hardware and software. Specialists in educational technology, in particular college and university faculty who conduct research and teach courses on educational technology, prefer the term instructional technology because it draws attention to the instructional use of educational technology. This term represents both a process and the particular devices that teachers employ in their classrooms. According to the Association for Educational Communications and Technology, one of the principal professional associations representing educational technologists, "Instructional Technology is a complex, integrated process involving people, procedures, ideas, devices, and organization for analyzing problems, and devising, implementing evaluating, and managing solutions to these problems, in situations in which learning is purposive and controlled."(p. 4). Educational technologists often employ the term instructional media to represent all of the devices that teachers and learners use to support learning. However, for many educators the terms educational technology, instructional media, and instructional technology are used interchangeably, and they are used so here. In addition, the principal focus will be upon the most modern computational and communication devices used in schools today.
