I've been looking a few new Common Core aligned curriculum units floating around, and while much concern today is justifiably on the difficulty of transitioning kids to CC requirements mid-stream, I'm not sure if the situation gets better after everyone's been introduced to ELA class based on a narrow range of textual analysis tasks and skills that change relatively little year over year..
Kids are supposed to start finding the theme in literature in grade 4. Are you going to re-teach that every year? At a certain point can you assume it? If kids haven't gotten it after three years, what are you going to do to make them start getting it? Should there be an implicit assumption, eventually, that you don't have to teach most high school students big blocks of the standards?
Most importantly, are kids just going to lose it after doing the same thing over and over?
