Ed Next’s triple-normative leap! Does the “Global Report Card” tell us anything?

Imagine trying to determine international rankings for tennis players or soccer teams entirely by a) determining how they rank relative to the average team or player in their country, then b) having only the average team or player from each country play each other in a tournament, then c) estimating how the top teams wouldContinue reading “Ed Next’s triple-normative leap!

Third Way’s “Revisionist Analysis” [Bold-faced lie!]

I know I said I’d stop addressing the Third Way report on Middle Class Schools, but I do have one more thing to point out. Third Way issued a memo in which it aggressively attacked my assertion that they had used district level data to characterize middle class schools. Again, this assertion was relevant toContinue reading “Third Way’s “Revisionist Analysis” [Bold-faced lie!]”

Newsflash! “Middle Class Schools” score… uh…in the middle. Oops! No news here!

I’ve already beaten the issue of the various flaws, misrepresentations and outright data abuse in the Third Way middle class report into the ground on this blog. And it’s really about time for that to end. Time to move on. But here is one simple illustration which draws on the same NAEP data compiled andContinue reading “Newsflash! “Middle Class Schools” score… uh…in the middle. Oops! No news here!”

Insult of insults from Third Way – Baker, You… You… Status Quo…er!

I gotta admit that my favorite part of the Third Way memo responding to my critique of their “Middle Class” report is the end of the memo. Here are the two concluding paragraphs from the Third Way memo in reply to my rather harsh critique of their report:  There are 52,860 public and charter schoolsContinue reading “Insult of insults from Third Way – Baker, You… You… Status Quo…er!”

Third Way Responds but Still Doesn’t Get It!

Third Way has posted a response to my critique in which they argue that their analyses do not suffer the egregious flaws my review indicates. Specifically, they bring up my reference to the fact that whenever they are using a “district” level of analysis, they include the Detroit City Schools in their entirety in theirContinue reading “Third Way Responds but Still Doesn’t Get It!”

One difference between Playin’ Jazz and Policy Research: Comments on the Third Way “Middle Class” Reply

Occasionally on this blog, I slip in some jazz references. I often see commonalities between jazz improvisation and policy analysis. But I think I’ve finally found one thing that is very different. A lot of jazz teachers will joke around with students about what to do when you’re improvising a solo over chord changes, perhapsContinue reading “One difference between Playin’ Jazz and Policy Research: Comments on the Third Way “Middle Class” Reply”

Piloting the Plane on Musical Instruments & using SGPs to Evaluate Teachers

I’ve posted a few blogs recently on the topic of Student Growth Percentile Scores, or SGPs and how many state policymakers have moved to adopt these measures and integrate them into new evaluation systems for teachers. In my first post, I argued that SGPs are simply not designed to make inferences about teacher effectiveness. TheContinue reading “Piloting the Plane on Musical Instruments & using SGPs to Evaluate Teachers”

On ignorance & impartiality: A comment on the Monmouth U. Poll on Ed. Policy

Some Twitter followers may have noticed the ongoing back and forth regarding the validity of the recent Monmouth University Poll on education reform.I’d certainly rather spend my time on more substantive discussion. As I’ve noted on many occasions, polls are what they are. They ask what they ask. And the responses to the questions mustContinue reading “On ignorance & impartiality: A comment on the Monmouth U. Poll on Ed. Policy”

Inkblots and Opportunity Costs: Pondering the Usefulness of VAM and SGP Ratings

I spent some time the other day, while out running, pondering the usefulness of student growth percentile estimates and value added estimates of teacher effectiveness for the average school or district level practitioner. How would they use them? What would they see in them? How might these performance snapshots inform practice? Let’s just say IContinue reading “Inkblots and Opportunity Costs: Pondering the Usefulness of VAM and SGP Ratings”

More on the SGP debate: A reply

This new post from Ed News Colorado is in response to my critique of Student Growth Percentiles here: https://schoolfinance101.wordpress.com/2011/09/02/take-your-sgp-and-vamit-damn-it/ I must say that I agree with almost everything in this response to my post, except for a few points. First, they argue: Unfortunately Professor Baker conflates the data (i.e. the measure) with the use. AContinue reading “More on the SGP debate: A reply”
