I recently gave a talk at ResearchED at Oxford, UK. The title of my talk was “Math Education in the US: Still Crazy After All These Years”. It described the sorry state of math education in the US and how it got that way. In particular, it pointed up the battle between traditionalists and progressives (math reformers) and how each approaches math education. It also discussed how the Common Core Math Standards extends the reform math ideology that has been alive and well for the past 25+ years in the U.S.
