Listening doesn't always require ears! Find an Internet chat room that discusses business topics like http://www.infinitydatacorp.com/index.html . There are a number of other sites. Do some exploring and either enter the chat room or look at transcripts of previous chats. Examine the participant responses. Are they paying attention to what is being said? Is the interchange confusing? Organize and summarize the contents of a particular session and then suggest ways listening techniques could be used during chat-room sessions.
