One of the most consistently recognized characteristics of CMC is the reduced number and variety of visual and auditory cues that are available. Some researchers, as we have just seen, feel that fewer cues encourage greater student participation. But others feel that the lack of cues can be associated with immature, insensitive, and unproductive behaviors. As a teacher, you should be aware that CMC messages can be misinterpreted and exchanges can become negative. Students involved in CMC can be sensitized to these limitations, learning to become more careful in the construction of the messages they send.
Schools frequently provide students with a code of on-line conduct, often called netiquette.
