Smart idea! I need to add this to the doc

Facebook has led to an extensive set of ideas and thoughts. (Somehow I haven't cultivated my network here on BlueSky.) I summarized ideas about how teachers can interact with families / caregivers in this document: docs.google.com/document/d/1...

yes! I agree with that for sure.

My undergraduates (middle school math methods) would like advice and insights for teachers' interactions with parents. Teachers or teacher educators, what advice or ideas would you give to these future teachers?

Neighborhood schools are closing across Arizona. It’s because of vouchers.

"The math is simple: Arizona doesn’t provide enough funding to adequately fund one school system, much less two — a public system open to all and a selective private system." @azmirror.com

OPINION: Arizona's $1 billion voucher program is forcing public school closures while subsidizing wealthy families

I spoke to a Venezuelan woman who was arrested in this raid and later released with her 4yo son. She said agents broke down their door, pointed guns at them and made sexualized remarks about Venezuelan women. When she returned to her apartment it was boarded up and all her possessions were gone.

The tears I just cried.

Jane Fonda, 87, has relaunched The Committee for the First Amendment, the organization of Hollywood stars and filmmakers that her father, Henry Fonda, helped found in September 1947.

May Jane's 550-person endeavor outlive Henry's.

ER doc here! This is a lie. Wait times are up because the American healthcare system is an unsustainable business model and a for-profit national healthcare system just doesn’t work. These problems will continue to get worse until we change that system. It literally has nothing to do with immigrants

Aaron Rupar @atrupar.com · 10d

Vance: "If you're an American citizen & you've been to the hospital in the last few years, you've probably noticed wait times are especially large & very often somebody who's there in the ER is an illegal alien. Why do those people get healthcare benefits at hospitals paid for by American citizens?"
