Conclusion
While sources differ in their precise estimates of the economic potential of Open Data, all are agreed that it is potentially very large. In countries which were early movers in Open Data there is already evidence of significant businesses having developed to exploit that potential. Leading governments have recognised that their role is not simply to publish data - they are supporting the whole value chain of the use of data through four distinct though interlinked roles. Other governments should consider how to use their Open Data to enhance economic growth, and should put in place strategies to promote and support the use of data in this way.

I am attaching the webpage of a very intresting article on Peer Instruction. Eric Mazur developed a very intresting teaching and learning method, based on interactive learning.

I find this article useful to answer the questions of (a) how do we prepare educators to embrace collaborative pedagogy, and (b) how do we negotiate the idea of collective intelligence?
