Over the past century, advances in technology have replaced the heavy hardware and metal wiring of the original design with lightweight microcircuitry. These advancements have also allowed for the transition from landlines to wireless, freeing people to communicate from remote locations. All over the world, millions of people can talk to each other, expanding businesses and improving relationships that might not otherwise have survived across long distances. Telephones also allow for instant communication, and new technology integrates video and Internet.
Purpose To develop an understanding of communication technologies and to appreciate the opportunities and problems that come with these technologies. Context Communication is the transfer of information and some means of ensuring that what is sent is also received.
Technology increases the ways in which information can be communicated, the speed of transmission, and the total volume that can be handled at any one time. Students need to experience firsthand how technology helps people communicate more information to more people in less time, with greater accuracy and fewer misunderstandings.
In this brief lesson, students will try out a few innovative examples of communications technologies and explain how they transform patterns of sound or light into patterns of electricity.

Motivation Let students explore the Technology at Home website. Although you will need the Shockwave plug in to try the interactive version of this activity, a text version is also available. This activity lets you go back through the century to find out when everyday items first appeared in homes.
Tell students that they will use this activity specifically to explore how technology has increased the ways in which people communicate.
Each student should jot down at least three examples. After students have spent about 15 minutes exploring the interactive timeline, discuss the examples that they selected. The samples provided include communication patterns that involve sound text-to-speech synthesis and an integer sequencer for use in solving mathematical problems.
Assessment The study of communications technology should help students move from being users of communication devices to understanding general communication principles and appreciating opportunities and problems that come with these technologies.
To help students develop this understanding, have students write a short essay in which they express their ideas about how advances in communications technology can present society with both opportunities and new dilemmas.
For example, students can begin to think about issues of privacy and invasion of privacy. Extensions Another resource on the PBS: A Science Odyssey website that can be used to teach the ideas covered in the Communication benchmarks is Radio Transmission:Telephones also allow for instant communication, and new technology integrates video and Internet.
Video of the Day The first telephones, as well as their modern counterparts, consist of a ringer, transmitter, dialer, switch hook, power source and anti-sidetone circuit, all of which have been advanced by new technology.
Students in a communication technology degree, such as a Bachelor of Science in Information and Communications Technology, take classes that cover a variety of topics, including technology, business, and management.
