4:31 PM | New Poll Reveals More Bad News for CCSS

Today's annoucement of results from the annual PDK/Gallup poll on public education reveals troubling news about Common Core. The poll, conducted by Gallup and Phi Delta Kappa International (PDK), measures the attitudes of Americans toward public schools, both in their communities and nationally. The results show that, overall, the public is satisfied with their neighborhood schools, but are less so nationally, with 51 percent giving schools a C. Tags: Common Core, standards, STEM &

"Ingenuity", "far reaching vision", "unerring sense", "deep
curiosity" — and best of all,
"extraordinary creativity". These are some of the words that have been
used to praise this year's Fields medallists at the International
Congress of Mathematicians (ICM). These words aren't specific to maths. They
could be used to describe anyone whose work is about discovery and
beauty; writers, poets, or musicians for example. If there has
been one overarching theme at this ICM, it's just how
