Yesterday I introduced our class blog, Google Reader and Google News to my Justice and Peace classes. We're just testing the blog right now, but I'll post links when we get going.
The other two are ways that the girls can start to get updates on what's going on regarding issues we will be studying, and maybe blog posts with some of the current thinking. Soon to come: I'll be showing them places to get encyclicals and Catholic perspectives, and through the course we'll try to do some reflecting and pulling things together.
For this class, though, I just had them find blogs and news about things that interest them. These are ways you can get current information about your own passions, without having to dig. The information is delivered to you, to your Reader or your News.
