Other selections - brand/reputational, operational (e.g., price to administer, score, etc.), legal/political pressures, market, and comparability to the past on top of the reliability and predictive validity.

Can we admit the SAT has not been optimally designed for how it is used? It has evolved over time. There is a founder effect and there are selections beyond performance that combine to give rise to likely a sub-optimal test.

@sethlfowler @neetu_arnold There are colleges that are staying test optional based on internal data.

@sethlfowler @neetu_arnold Poor admissions team that isn't using all the data that is available regarding predictors of academic success in college. They did the easy ones and removed one of them without modeling the impact.

University of California STEM professors want standardized tests back due to severe math deficiencies among students: “We now observe preparation gaps so severe that instructors must reteach middle school mathematics” “The current admissions metric, based primarily on GPA & essays, can no longer reliably distinguish readiness for university-level STEM majors in an era of severe grade inflation & AI assisted application essays”

Schools needing SAT/ACT with GPA may be telling you their admissions team isn't looking at all the data available and taking the easy route.

Colleges have more than GPA and SAT/ACT scores from students that are useful for admission-schools applicants attended, the classes taken vs. those offered, AP scores, grades in college courses, etc.

Hypothesis: Declining student performance in the U.S. may be partly influenced by the fact that educational systems of the 21st century were directly & indirectly designed, shaped, influenced, and led by cohorts with historically high childhood lead exposure.

Really appreciate @janecoaston having me on her show to discuss our Harvard/Epstein series: youtu.be/6cnBjLyzooI

We found the secret “Jeffrey E. Epstein Fund for Women’s Athletics.” It opened a new rabbit hole into how the billionaire pedophile used Harvard to launder his image. And why the world’s richest university whitewashed its own Epstein investigation 🚨👀 youtu.be/V1JclWYNwHQ?si…

“No child deaths were directly linked to COVID19 vaccines, according to the FDA’s long-awaited analysis..former CBER director Prasad claimed in a leaked internal memo that ‘at least 10 children have died after & because of receiving COVID19 vaccination.” biospace.com/fda/fdas-own-r…

There is growing evidence from the ship that you probably don't need "prolonged close" contact to spread the virus. And the implications here are pretty clear If we are serious about ending this outbreak, all the passengers should undergo a full quarantine away from others

@tppwastaken @SethLargo Ours is the same. Students are creative. The question is how much effort do faculty and staff want to put into enforcement.

@SethLargo @kstrna62 In my jurisdiction (NJ) they have a full ban, even during lunch etc. The photel thing was already sth that was already being done. My theory is that most supporters of cell phone bans in US schools underestimate the extent and enforcement.

We need to kill this narrative. Over the last few years, the concerns about tech in K-12 had little to do with test scores. The concerns were psychological, social, and spiritual. Don't let the media do this "oh, scores haven't improved" thing. It'll be a back door for tech to return.

@GoldbergDoron @tylerblack32 My son has ADHD. Wife did not take acetaminophen when pregnant nor has she in a long time. She is allergic as is her mom and maternal grandmother.

@tylerblack32 No, you are wrong. Adhd is caused by acetaminophen in pregnsncy achildhood. So many good evidence. All prospective. 91 scientist wrote concensus statement about it in 2021. Its is time realize adhd is real epidemic caused by the most used drug.

🧵ADHD Myths 🧵 🚫"ADHD isn't a really thing" 🚫"ADHD is normal its just kids being kids" 🤦‍♂️"ADHD is overdiagnosed" ALL WRONG The first ignores the biology. The second ignores the severe outcomes. The third ignores the nuance. Thread ⏬ /1

@marcportermagee According to my son, they are doing a good job at his school of still using the cell phones. Though he is salty as he doesn't have one.

It’s worth remembering that at the time the bans were proposed a lot of skeptics said kids would just ignore them and find workarounds

We are clearing the basic threshold of can these bans reduce cell phone use. That alone probably justifies their continued rollout. Probably too earlier to expect big gains in achievement.

@Noahpinion The even more interesting thing to know is that almost all schools that tried a smartphone ban keep it, because they like the results.

The interesting thing about smartphone restrictions in schools is that MOST PEOPLE SUPPORT THEM, even though everyone has a smartphone! Social-mobile is a "product trap" -- it's something people would like to quit, if they could also get everyone else to quit at the same time!!
