Thanks to the bloggers who helped flesh out this analysis of math scores in the current issue of New York Teacher. It was awesome to connect in the b’sphere with a math teacher from Brooklyn, whose comments to a post added insight from the classroom, and another blogger, Chris Correa from UMichigan. Correa, "introduced" by frequent Edwize commenters JennyD and institutionalmemory, ran some further numbers for us to show what we suspected but hadn’t proved–that there was a definite decrease in the number of students tested in the weaker school districts–very possibly bumping the scores up artificially. Yes! to the power of blog.
