Based on the Gates-funded Common Core Curriculum Maps, and the general reaction to them thus far, at the high school level these standards won't be taken much more seriously than any other set of high school standards at first.
What's going to come down the pipe shortly thereafter, however, will be a generation of very consistent, narrowly-focused and predictable high school tests, end of course tests, formative assessments, etc., which are exactly aligned to the standards as written, as I'm reading them here. They will also be fairly hard.
So, while schools that aren't really worried about passing the tests thanks to their affluent population can afford to follow, say, this Common Core Curriculum Map, since it is rather loosely aligned with the CCSSI standards, schools with students at risk of not passing the tests will experience a whole new paradigm of rigorous test prep in the high school ELA classroom. A paradigm well suited to hybrid and online instruction.
Why do you think Tom Vander Ark is so excited?
