The document defines educational technology as the development, application, and evaluation of systems and tools to improve the process of human learning, including both low-tech tools like pictures and high-tech tools like computers. It discusses how technology can be used for passive instruction, interactive instruction, as a learning environment, an information resource, to distribute education, and for testing and diagnosis. The document also cautions that technology should serve instruction rather than be adopted merely for its own sake.

adopted merely because it
exists, or because an
institution fears that it will be
left behind the parade of
progress without it.”
