I just came across a new study today about ebooks and ereaders in the classroom. Unlike other surveys, this one focused entirely on k-12 educators. A total of 1300 responded to the poll.
I only have the executive summary, but that alone makes for fascinating reading. 40% of teachers and 50% of librarians have bought ebooks. I was surprised to discover that of the librarians who bought ebooks, they purchased an average of 844 ebooks over the past year. And of the teachers who bought ebooks, 70% did spend their own money. Curiously enough, teachers were more likely to buy ebooks for professional development than for the classroom.
They complete survey results are being sold for $99. I think it's worth it.
