Just reblogging from teaching.puregin.org: I posted my slides and some other material from my OpenWeb Vancouver 2009 talk on “Open Books, Open Minds, Open Source”. This talk explored how the conception of “openness” in information and knowledge, in the context of teaching and learning mathematics, has changed over the past 2400 years of mathematics education.
In particular the timeline of Education and Technology technology which I made can be found here: http://www.puregin.org/exhibits/edtech/edtech.html
