I'm not sure why it took me so long to figure out Rollyo....maybe from lack of sleep or it could be because I'm just a little slow, but what a really neat idea. Building your own customized search engine allows you to filter out what your students don't need to focus on, and let's them get results that you want them to get. It's such a great idea...why didn't I think of that?
I can see this a big plus for research teachers who are having problems getting their students to focus on the task at hand. This site, allows teachers to actually go in, and create their own sites of where the search should take place. Very cool.
