Wikis are an amazing resource for education! I am happy to report that this is a tool I am actually familiar with in my day to day life! This year, I actually taught my coworkers about the use of wikis! As a grade level, my colleagues and I group all of our 175 fourth grade students into several ability groups. As time progresses, students are constantly moving between levels. At first, the other teachers would pass around a spreadsheet crossing off and adding names. Kids were being forgotten, double added, and improperly placed all of the time! We began using a wiki to update group lists, and it's changed everything! Wikis are a wonderful tool!
