While the Twitter chat really only involved David, myself and Laura Gogia a group of learners joined us on on the #hacksession to create a code.
I always use a codebook when teach annotation. As these annotations become social the codebook evolves into a series of tags.
Our goal was to create an open codebook (click here for the doc) to be used once we start to do the #QuestionTheWeb activities with students.
I enjoy Twitter chats that go beyond the echochamber. Granted this works in small chats like #QuestionTheWeb (n=3) but doing open #hacksessions is a great way to give voice to educators and students.
