Last fall, as a follow-up of my participation to CONSEGI 2011 in Brasilia, and in the context of my Open Data for Education proposal, I asked several Brazilian teachers to share if and how they were using Open Data to teach. These are, in no particular order, the first answers I got. I hope they will stimulate more contacts and exchange of experiences and best practices in this field, among them, and all other teachers worldwide who are interested in this topic.
