The Debate Itself
The final step of this Webquest for Nothing But the Truth is the debate between the two viewpoints. Be sure to emphasize that everyone should remain civil in this discussion. If you have split your class in half, and each side has made one glog, then have the sides draw straws or flip a coin to see who goes first. Give each side a certain time limit to go through their glog and any other materials they are using, and then hear the other side.
For purposes of evaluation, you can grade professionalism in the editing of the glog, the quality of the materials presented, and the support for the argument made.
If you have students make individual glogs, you can either go "point-counterpoint," having students alternate, or you can have one entire side present, and then the other side -- that could get repetitive, though.
No matter what, you will have students thinking about the issues during this language arts Webquest on Nothing But the Truth long after they have finished the book.
