I've nearly finished going over all the projects, and can see already things I want to change for next year. Some things I did like. One little piece of outside-the-box thinking (at least, outside the classroom, outside the state!) was the inclusion of a video chat with someone in Washington D.C. The video gives added interest to the students' wiki page.
Another student who with her partner researched world hunger, discussed (through e-mail?) poverty in Pakistan with her grandfather who is a lawyer there. It was wonderful to see how animated she was in telling the class about things she had learned about a country dear to her heart. Another wrote to Michael Nacht, an expert on national security, for his views on terrorism. That's what I'm talkin' about... learning can go beyond the textbook and beyond the classroom walls now.
I need to work more with students with how to go about crediting sources for specific information and for photos. They also need to do more analysis with the information they uncover. But it was a good start, I think.
