Don't miss this important new study by the National Council on Teacher Quality regarding the preparation of competent elementary-school math teachers. Titled No Common Denominator, it finds, after reviewing a national sample of ed-school-based undergraduate teacher prep programs, that fewer than 15 percent of them require enough of the right kinds of courses. It names names, too! It also makes a boatload of recommendations, nearly all of them contrary to current practice and some of them??also contrary to??conventional teacher-quality-reform wisdom. All this was unveiled earlier today (at a well-attended event on the roof??of the Hotel Hay-Adams, looking down??upon the White House itself). If you'd been there you'd have enjoyed a fine presentation by top NCTQ policy analyst Julie Greenberg. Second best is to read what she wrote--there are PDFs for the press release, executive summary, and full report (and a version with full appendices).
