The folks I mention here are already pushing back on this piece @DianeRavitch so in lieu of direct social media battles I’m going to just “reply all” with a new point:

Let’s talk “peer review.” The #schoolvouchers crowd has made use of this fuzzy term for years.

1/
“Peer review” can mean a lot of things. For example this paper by Corey DeAngelis in something called the “Journal of Free Enterprise” is “peer reviewed.”

Sorry but that’s just not JPAM or AEJ: Policy or EEPA and anyone credible knows that. 🤦‍♂️

2/ Image
And a number of “peer reviewed” studies come from the working paper series at UArk that Jay Greene founded, which—at least when I reviewed for them years ago—paid $250-500 a pop.

3/ Image
“Peer-reviewed” to the #schoolvouchers crew is like the word “rigorous.” It’s a way to sell industry-funded research to policymakers and the press who don’t have time to dig into it.

I’m sure you can find “peer review” that says #covid19 vaccines don’t work too. Etc.

4/
That’s why I wrote the post @DianeRavitch: precisely to highlight this problem.

5/
And if you look at my list here (also linked on Diane’s site) *of course* there are some + #schoolvouchers studies. But these occurred largely 10+ years ago on small pilot programs.

My point in this post is it all comes from the same group. And me.

So let’s talk about me. The voucher crowd still cites this PSJ study of mine from a decade ago that found tiny positive #schoolvouchers impacts on attainment.

I don’t deny nor denounce that. But it comes from the same ecosystem and would never been accepted today. Why?

7/ Image
Because we identified #schoolvouchers impacts on Milwaukee kids using a matched sample with no pre-treatment measures. Not just on outcomes—no pre-treatment covariates at all.

It was fine for 2013 and went through peer review but it would have been rejected today.

8/
And btw the #schoolvouchers crowd including especially Corey still use this sub-par matched sample 17 years after it was created, to publish articles on de jour outcome variables like “character.” They do it because quality research isn’t the point.

9/
The point of this activity is simply to flood the zone with studies to “up the count” and make it seem like studies are on balance positive for #schoolvouchers. They aren’t. It just seems that way because the same people are recycling data sets with new outcomes.

10/
That’s why in my post on Diane’s site I pointed to affiliations not papers. Counting papers and reports is misleading. Count the people and institutions instead.

The #schoolvouchers crowd loves to site my decade old PSJ paper using matched Milwaukee data to show small positive effects on attainment.

But they ignore my 3 other studies in far better journals that look awful for vouchers and are more informative to policy today

1/
First up in @EEPAjournal: in “Life After Vouchers” we show low-income and Black students exit #schoolvouchers at higher rates and DO BETTER once returning to Milwaukee Public Schools @DianeRavitch

Next up in @aerj_journal in “Going Public” we deep dive into those kids who give up #schoolvouchers and show they are historically underserved and come from “pop up” voucher schools founded to take tax $

🚨A new front has opened up in the push to privatize #schools.🚨

At Fox News Jeb Bush explicitly cited #soldastory as a reason we need #AZEd #schoolvouchers. @edvoters @BadassTeachersA @Network4pubEd @PV4PS 👇

#Reading is going to be the new wedge issue to pitch #schoolvouchers /ESAs to parents understandably frustrated at #scienceofreading issues but who were turned off by the voucher culture war pitch.

2/
Just days before writing this Fox column and citing #reading as a reason states need #azed style #schoolvouchers Bush was honoring voucher hero @DougDucey at the annual ExcelInEd meeting

And #schoolvouchers activists exploit parent frustration over what’s often real inadequacy of some public districts to meet special needs.

But vouchers as a fix are based on a theory of action assuming district neglect—when really districts themselves are under-resourced.

1/
#schoolvouchers advocacy organizations stand up parents of these kids like other Right-wing groups go plaintiff-shopping in legal cases. Promising them vouchers as a cure-all.

2/
The name of the game for political #schoolvouchers activism is to build coalitions of support based on false promises, when the reality delivered will be a narrow constituency of families already in private school.

Hey 👋 #educators and defenders of #publicschools:

Got an angry #MAGA family relative at your #Thanksgiving 🦃 table who likes to yell at you about #publiceducation?

Here’s a short “well actually” sheet to 👏 back:
@Network4pubEd @NPEaction @PV4PS
1/
“I’m sick of just throwing money at #schools that just waste it!”

Well, actually, Aunt Betsy, investing in #publiceducation is one of the best things taxpayers can do—more $$, better outcomes. @KiraboJackson

2/
“And all this crime you damn liberals have going around too!”

Well, actually, spending more $$ on #schools helps reduce long term #crime rates too! @fordschool @BrittanyEdPol @JasonBaron4

I always go back to @matt_barnum on this, who said we need to take seriously the alarm from school leaders even as we explore the mismatch with admin data.

1/
It’s silly to argue that admin data show anything like a crisis on teacher exits. Those data don’t.

But I’m surprised that with advent of mixed methods in policy research more folks aren’t looking for ways to join both #educators perspectives and admin data.

2/
I suspect some of this comes down to the same old difference in the way economists study data without always interrogating sources.

Before he was peddling #schoolchoice as a “solution” to woke:

Jay Greene/Heritage less than a year ago explicitly argued the Right should fuel culture wars to advance a fringe agenda—mainly #schoolvouchers
@Network4pubEd @NPEaction @PV4PS @pastors4txkids @BadassTeachersA

1/5
Greene also pushed pseudo-science arguing against health care for #LGBTQ+ kids.

Using as a flimsy an evidence base as the #schoolvouchers data he’s flooded the zone with for 20+ years

2/5
It’s critically important to understand the links between shoddy #schoolvouchers research showing positive impacts, and these pseudo-studies.

Two sides of the same @BetsyDeVos -based agenda.
