During our last chapter of the social studies textbook, students used the following webquest to learn about the Underground Railroad. http://www.greece.k12.ny.us/ath/library/webquests/underground/default.htm
When students finished the webquest, they shared their keynotes with the rest of the class. It was one of the few times this year I let the class view each individual keynote with the whole group at one time. Usually to share or celebrate a finished product, the class did a Walk About Review.
During a Walk About Review, students sit their computers on top of their desk while students strolled quietly from computer to computer observing the work of their peers. This type of sharing is much quicker then watching 23 keynotes or projects for an entire afternoon. It still allowed the class celebration time.
