Interested in improving education? Interested in education policy? Then the education carnival is for you hosted at The Colossus of Rhodey. It’s not just lesson plans and theory. If education is your thing you can also check out the A Teacher's Life blog carnival and don’t forget the Carnival of Homeschooling.
Lots of interesting postings regarding various history topics can be found at Historia i Media. This blog is written in Polish, but a large majority of the submissions are written in English so just click through the submission links and be surprised at what you discover if you don’t have a translator program.
Finally, don't forget the last edition of the Georgia Canrival which can be found here.
