Have students break into the groups that were self-selected last week and discuss their
assigned article
                                                                                          1
Each group numbers off within the group  Group A has participants 1-6, etc. Have
people combine into new groups based on their number (all of the 1s, 2s, 3s, etc).
Now each new group contains one member from each of the previous groups. They
are now the expert and share their article information with their small group. Have
students summarize as a class at the end.
