Learning about the standards writing process from NGA news releases. Take 2.

About a year ago I noticed there was a lot of misinformation being spread about the process for writing the standards, so I came up with the brilliant idea of pointing people to the historical source documents that chronicled the process: the NGA press releases about the Common Core during 2009–2010. That will solve the problem, I thought; people will just read the press releases and figure it out. Boy was I ever wrong. In this post I’ll try to give a clearer timeline of the process. Along the way I’ll point out the involvement of testing organizations, since I think that one of the reasons the misinformation has survived for so long is a narrative, compelling to some, that the testing industry dominated the process. (Spoiler alert: they didn’t.)

First, here is the list, with an additional one from July 2009 that I missed last time (which has been the source of much confusion):

Notice that there seem to be duplicate announcements of the Work and Feedback Group and duplicate releases of the standards. What’s going on here is that there were two documents. First, in summer of 2009, the people listed in the July 2009 release worked on the document that was announced in September of 2009. That document, which was actually entitled College and Career Readiness Standards for Mathematics, was confusingly referred to as Common Core State Standards in the title of the September 2009 press release. If you take a look at it you will see that it is a draft description of what students should know by the end of high school.

Subsequently, as described in the November 2009 press release, a new process with new groups was started, to produce “K–12 standards.” These were to be a set of grade level recommendations that described a pathway to college and career readiness. For the K–12 process, there were about 50 people on the Work Team and about 20 people on the Feedback Group for mathematics, representing a wide range of professions, including teachers, mathematicians, policy makers, and one representative each from College Board and ACT … none representing for-profit providers of assessments. The members of this group are listed in a linked pdf in the press release.  This is the document that was released for public comment in March 2010, as described in the March 2010 press release, and released in final form as the Common Core State Standards on 6 June 2010, as described in the final press release.

As you can see from the list of members, I chaired the Work Team for the second document. Within the work team there was a smaller writing team consisting of myself, Jason Zimba, and Phil Daro (who had all been involved in the summer 2009 document, Phil Daro as chair for mathematics). We based the standards on narrative progressions of particular mathematical topics across grade levels that were solicited from the Work Team. We circulated many drafts to the Work Team, the Feedback Group, the 48 participating states, various national organizations such as AFT and NCTM, and, in March 2010, the public (see the March 2010 release). I personally made sure that we responded to and made considered decisions about all of the voluminous feedback we received.

When you hear people claim that “the standards were written by the testing industry,” they are probably referring to the first document, because of the greater involvement of College Board and ACT. Both organizations, along with Achieve, which was also represented, had conducted research into the requirements of college and career readiness. (All are non-profits, by the way.) The problem is that some people refer to the first document in a way that suggests they are talking about the second document (i.e., the actual K-12 standards adopted by states). That is an error and a misleading one.

The two documents are different in nature, of course, since one of them is just a picture of an endpoint while the other is a progression. Feel free to compare them. One influence of the first document on the second is that in the first document you can see the first draft of what became the Standards for Mathematical Practice. And the topic areas listed in the first document evolved into the high school conceptual categories in the second. All this evolution happened under the processes for the second document, with input from the various groups described above.

I think the second document is the work of the 70-odd people listed as the Work Team and Feedback Group in the November 2009 press release. But, just for fun, I put the teams for the two documents together and counted how many of them came from ACT and College Board (no other testing organizations were represented). It comes to a total of 81 people with 7 from ACT and College Board, about 9%. So even with this interpretation the claim that the process was dominated by the testing industry is false.

Drawings in the Common Core

There’s been a lot of talk recently about the Common Core and drawings. I won’t get into the politics of that here—that’s for my other blog—but, politics aside, there is an important question of interpretation, and possible misinterpretation, of the standards here. Let’s look at the wording of standards that talk about drawings.

Problem with RSS Feed for Forums Fixed

The link to the RSS feed for the forums (on the right of this page) was broken. I’ve fixed it now. You might not have noticed (I didn’t for a while) because it was simply not updating. So if you are using an RSS reader to follow the forums, you should delete your old feed and add the new url. If you don’t understand this message, ignore it!

Task Talks

Are you interested in engaging with other educators about tasks for the mathematics classroom?  Illustrative Mathematics is starting a weekly conversation about tasks, called Task Talks.  Join the community on adobe connect every Monday night from 7pm Eastern to discuss the task identified on our Facebook and Google+ pages the previous Tuesday.  Use it in your classroom, use it with future teachers, or just ruminate on it throughout the week and join us for a discussion on Monday night.

This week we have chosen a fourth grade task about subtraction.  If you think you might join, please let us know here.

Hope to see you there!

Zimba Zoomba

For extra added fun, the folks over at Edutron have created a popup version of Jason Zimba’s monster graph of the standards, so that when you mouse over a standard the text of the standard pops up (the mouse over effect doesn’t work in Preview on a Mac, you have to actually click on the standard).

Tips on searching this blog

I have finally discovered a forum search feature that works. So the box on the right now searches both the blog posts and the forum topics and replies. Here are three ways you can search this blog:

  1. Use the box at the right.
  2. Use the google site search feature: google “site:commoncoretools.me irrational number” if you want to find stuff on the blog about irrational numbers. This also returns hits from pdfs on the blog, e.g., the Progressions.
  3. Go to this old post and do a word search directly from your browser. It goes on forever, so you might to wait until it fully loads.
  4. I think (2) works better, but (1) is slightly more convenient. (3) is a last resort when you get frustrated.

[Update, 1/28/14: (1) stopped working, but I have found a new widget that implements a google site search, on the right. I'll make this post unsticky now in the hope that we have finally solved the problem.]
