Right now, I am kicking around asking a department or level to take their things online. For example, I would like to take the English department (9 teachers total) and have them collaborate on documents like curriculum maps or lesson plans using Google Docs, share ideas using blogs, and sharing all of their files for their classes in an online storage space. This way, all teachers teaching similar classes can easily share their documents.
We are also kicking around some schedule changes at our school. I think this type of collaboration would be great at getting feedback and having people give their input on a subject.
Once I get the teachers involved, I hope they will start using this for the students.
