If you have never used or heard of Yaplet I would suggest giving it a try. Yaplet allows you as well as your students chat on any website at any time. If you are assigning students to find a particular DE Streaming clip they can use yaplet to chat with each other about the clip they are searching for. It allows for peer collaboration within the computer lab as well as anywhere else in the world with computer access. You can monitor your students by joining the chat or by simply watching what students are typing to one another. This is a great tool for students to use to look at and evaluate other internet resources.
