A useful tool in an EFL classroom is a stupid looking cuddly toy (I use a monkey myself), or if you just can t bring yourself to have one of those with you, try a bean bag. I have tried doing the following activity with a pen but found that one student complained on the grounds of health and safety. She said I could have someone s eye out! The icebreaker goes like this: 1. Arrange the chairs into a circle if possible. Students can sit or stand for this. 2. Introduce yourself according to the class level. For example, with absolute beginners you might just say your name and point to yourself or at advanced level you can explain your background in teaching and any interests you have. 3. Now throw the toy to someone else and ask them to introduce themselves. Sometimes a raised eyebrow and expectant look does the trick. 4. After the student speaks, indicate that they should throw the toy to someone else. 5. Keep going until everyone has introduced themselves, then retrieve the toy. 6. This time you throw the toy to someone else and you introduce that person. So, you say their name and whatever you remember about them. 7. Indicate to the student to throw the toy to someone else whose name they remember and keep going until you ve covered everyone. Encourage the rest of the class to help if someone gets stuck. 8. The activity ends when someone finally introduces you again.

The separate use of upstream and downstream channels, as we have seen in Figure 13.2, offers the potential for a 2:1 better use of the spectrum. However, in addition, the fact that, even during a communication, the participants are neither `talking' nor `listening' for a good proportion of the time, leads to a possibility for further statistical multiplexing. This makes for very ef cient carriage of `bursty' data, as we explain next by means of an example.
