I can't say much for the mechanics of the site itself, but I am interested in literacy awareness and education programs, so this is something I can see myself getting involved in.
I just visited the Constitution Center for the first time today. I learned a lot and recalled a lot i learned in school. It was a lot of fun! This page gives educators a resource for class trips and educational opportunities.
I have already used these for tutoring and assessment purposes. These are fun prompts that span a wealth of different topics. Good for elementary school, and maybe middle school.
