As states and districts begin the work of turning common academic standards into curriculum and instruction, educators searching for teaching resources are often finding that process frustrating and fruitless. Teachers and curriculum developers who are trying to craft road maps that reflect the Common Core State Standards can find themselves in a dispiriting bind: Their current materials fall short, and there is a dearth of good new ones to fill the void. Such frustrations are widespread. A report last fall by the Washington-based Center on Education Policy found school districts divided about how much curriculum change was truly required and reluctant to move forward with common-standards implementation, in part because of inadequate guidance from their states. Ironically, educators' frustrations take shape during an unprecedented buzz of activity to build knowledge about the standards and prepare resources for them. States and districts are bringing educators together to discuss the fundamental shifts demanded by the standards, which were unveiled in 2010. Advocacy groups and architects of the standards are holding workshops and posting documents and videos on the Web to illustrate new ways of thinking about and teaching what many now call simply "the core." But those messages have yet to reach everyone, and the resources and discussions taking shape online can be tough to locate. Not everyone supports the new standards, however. And some educators who don't are quite content with the complications of the current landscape.
