It is important to remember that content is first and technology is second. When you know what you are going to teach, then you begin to think about the "how"- maybe technology.
The next thing to think about is student accountability. If we do not hold students accountable, it will be easy to turn stations into busy work that have nothing to do with objectives, thus reducing the rigor and relevance.
I like the Fractured Fairy Tales and the Construct a word on Thinkfinity. The first is very good for a genre study on fairy tales. It really allows for creating a fairy tale and the second would be good for a station on word work.
I liked the Study Ladder activities, especially those associated with reading genres. There were some really interesting ones that could be integrated with social studies.
