The report offers a surfeit of evidence to suggest that students who use generative AI are already seeing declines in content knowledge, critical thinking and even creativity. And this could have enormous consequences if these young people grow into adults without learning to think critically. 🍎🎢

This is such a cool illustration of how the Mercator map distorts the size of Greenland, which looks as big as the whole continent of Africa on that map but is actually the size of Mexico.

This photo was taken in 1911 using glass plate technology by Herbert Ponting who was part of Scott's Antarctic expedition,
The composition and detail are exquisite with the band of white snow/ice creating a perfect frame around the two people and the ship in the distance
Iconic imo

In #mathstoday, I motivated z-scores by asking who was faster - Michael Phelps or Usain Bolt?
In past years, I had done this after introducing z-scores, but starting with the question prompted great discussion:
"You can't compare them. They're different sports."

Within 10 minutes, we'd gone from a seemingly impossible question to inventing a formula. They understand the purpose and the reason behind the calculations.
