In my library I think this would come in handy as a place for students to post comments about books they are reading. A digital book club could spring out of a wiki. They would be an excellent vehicle for GATE students.
Another suggestion might be for the California Young Reader Medal committee to establish a Wiki with this year's choices and open it up to students and educators to respond and comment. Teachers and Librarians could submit suggestions (because you know we all do it differently) and the students could offer their opinions on characters and plots. Authors and illustrators could also be offered a platform through a CYRM wiki.
On a side note . . . I held my technology lessons with teachers at our opening day inservice (our students returned to school on July 11th!) and their favorite item was Del.i.cious! They all were receiving new laptops (courtesy of a very supportive principal) that afternoon and the idea of "portable" bookmarks" was a hit. At today's staff meeting it was heartening to see each of them with her laptop open and taking digital notes. Along with our site technology rep and the district technology educator we will be doing a mini tech lesson at every staff meeting this year. Like I wrote before .... we have a very supportive principal!
