STANDARDS
Standards compiled from learning activities:
International- Intl. Technology Education Association: Standards for Technology Literacy
• Category The Designed World
• Standard 17Students will develop an understanding of and be able to select and use information and communication technologies.
• Grade Range 9-8
 Benchmark PThere are many ways to communicate information, such as graphic and electronic means.
Graphic communication systems involve the design, development, and productions of visual messages. Examples of graphic systems include printing and photochemical processes, while examples of electronic systems are computers, DVD players, digital audiotapes, and telephones. This information can be expressed in various forms: electrical information can be formatted as digital (discrete bits) or analog (continuously variable signals). Multimedia combines information from a number of formats (audio, video, and data) and then transmits it. Television studios and telephone companies exemplify businessess that deal with multimedia.
 Benchmark QTechnological knowledge and processes are communicated using symbols, measurement, conventions, icons, grapic images, and languages that incorporate a variety of visual, auditory, and tactile stimuli.
For example, the international symbols developed for transportation systems have helped to communicate critical information to traveler: a circle with a slash represents "No" or "Do not do." Emerging technologies often generate new symbols, measurement systems, and terminology. For example, ;-)is a symbol used in e-mail and on-line chat rooms to represent a wink. The development of the computer has spurred new terminology, such as gigabyte (a unit of computer storage capacity equal to one billion bytes) and nanosecond (one billionth of a second).
