Additional Ideas for Developing Investigations and Learning Experiences and Suggested Extensions to Learning in Technology/Engineering are in Appendix III.

Please note: For grades 6-high school, there are suggested learning activities after each set of learning standards. The numbers in parentheses after each activity refer to the related technology/engineering learning standard(s).

Communication Technologies

Broad Concept: The application of technical processes to exchange information includes symbols, measurements, icons, and graphic images.
6.1 Identify and explain the applications of light in communications, e.g., reflection, refraction, additive, and subtractive color theory.
6.2 Explain how information travels through different media, e.g., electrical wire, optical fiber, air, space.
6.3 Compare the difference between digital and analog communication devices.
6.4 Explain the components of a communication system, i.e., source, encoder, transmitter, receiver, decoder, storage, retrieval, and destination.
6.5 Identify and explain the applications of laser and fiber optic technologies, e.g., telephone systems, cable television, medical technology, and photography.

Suggested Learning Activities

  • Give an example of the following types of communication: human to human (talking), human to machine (telephone), machine to human (facsimile machine), and machine to machine (computer network). (6.4)
  • Create specific types of communication: human to human (e.g., talking, telephone), human to machine (e.g., keyboard, cameras), machine to human (e.g., CRT screen, television, printed material), machine to machine (e.g., CNC, internetworking). (6.2, 6.3, 6.4)
  • Explain what is meant by the size and focal length of a lens and its application for light theory. (6.5)
  • Research a communication technology and the impact lasers or fiber optics have had on that technology. (6.4, 6.5)

Boldface type indicates core standards for full-year courses.
