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

September 30, 2011


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 would […]

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

September 29, 2011

Comments Off on 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 to […]

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

September 26, 2011


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 and […]

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

September 24, 2011


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 schools […]

Third Way Responds but Still Doesn’t Get It!

September 24, 2011


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 their […]

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

September 22, 2011


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, perhaps […]

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

September 22, 2011


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. The […]
