Common Core Standards Research

I just want to give a quick follow up to my blog about the Common Core Standards.  The Brookings Institute released a report found here that questions whether or not the standards will have any positive impact on student achievement. Interestingly enough, the report does not talk about student learning; rather the conversation revolves around student achievement. I believe achievement and learning are two separate entities.  A student may learn a lot but achieve very little if they cannot translate their learning to a test. I assume that the author is using "achievement" and "learning" interchangeably and that the Common Core will not increase either one.
