What can a teacher write to introduce a communication technology class?
The teacher should begin by reviewing the communication model, and then point out that this course will concentrate on the medium and elimination of the static. The language of communication can be discussed next, pointing out the difference between verbal communication and communication via symbols and mathematic construction. The teacher should then review binary theory and make sure the students understand how it applies to electronic signals. The teacher could then outline the kinds of interference to expect in modern communication technology – bad code, misaligned signal senders and receivers, the failure of automatic verification systems, etc. When the students seem ready to enter the discourse, a discussion of the rapid changes in electronic communication could ensue, with concomitant warnings to keep up with progress.
