If you haven't already, I would email Dr. Lin:
cylin at siu • edu
To say you want to join all Jerry Becker listservs related to math education.
This is often where I see relevant announcements (including manuscript calls!).
Below is a screenshot from just now querying `Jerry Becker` in my gmail:

yeah, seriously. I'm sometimes down for authoring/coauthoring. I don't have expertise in sociology nor do I know the journals you might be targeting, but if you take that route for something math edu e.g. off of a fascinating manuscript call, lmk. +I'll keep my eyes peeled and lyk if I see sociomath

I have lots of (former) math teacher friends who have been writing curricula. If you're interested in an awesome gig in this space, check out BEAM's current offerings (link: www.beammath.org/work-at-beam)
It's a GREAT organization (check it out if BEAM is new to you!)

I can see local coverage in that sense by looking up the reported names; but those sites and affiliates (e.g. Fox) still source the info to ProP.

ProPublica presumably not MSM? Because that's where I have seen them.

lol yes I'm skeptical of the entire endeavor
A while back I got an alert about someone citing an article of mine in Smithsonian Magazine about calculators in math education.
... except no such article has ever existed! The citation looked realistic but it was all AI slop. Years later, no better.

ps. I should've written p≥5. I think it can fail when p=3, too

my recollection is the proving it mod p is pretty doable, you can write out what it is saying and it's not surprising
but p² is subtle
and p³ is madness!!!
