There are two fundamental facts about human memory that everyone should know. Working memory is one of them and Daisy explains it brilliantly here. This is also why "there's no need to memorise facts, I have the whole Internet in my pocket!" is bad and wrong.

Replying to @PCSnow1604
That's why I think opportunity cost is the single most important idea in school improvement. Every hour our teachers—and our students—spend on one thing is an hour they don't have to spend on something else. And this matters most of all for students who find learning hardest...

We remember the heroes of the Warsaw Uprising of 1944! The Warsaw Uprising was the largest effort by any European resistance movement during WWII. It was brutally crushed by the Germans after 63 days of heroic fighting. As a result of the German atrocities, over 200,000 civilians were killed. Warsaw, one of Europe’s most beautiful cities, was reduced to ruins. Pictured: the late Zbigniew Rylski "Brzoza" – the last soldier of the legendary ‘Parasol’ Battalion.

On this day in 1944, after 63 days of almost unimaginable sacrifice, the Warsaw Uprising came to an end. The men and women of the Polish Home Army had fought street by street, cellar by cellar, often with little food, medicine, or ammunition. They had faced one of the most powerful war machines in Europe and held out far longer than anyone could reasonably have expected. When the agreement ending the fighting was signed, the surviving insurgents were granted prisoner-of-war status. For Warsaw’s civilians, however, the suffering was not over. They were driven from the ruined city, leaving behind homes, churches, schools, family photographs, and the graves of people they loved. Warsaw itself had been shattered, but the spirit behind the uprising was not. October 2 is now observed in Poland as the Day of Remembrance of the Civilian Population of the Warsaw Uprising - it is a day to remember not only those who fought with weapons in their hands, but also the ordinary people who endured hunger, bombardment, executions, displacement, and the destruction of almost everything familiar to them. Yes, the uprising ended, but the memory did not.

Are we assuming that each of these ideas can be implemented well by every teacher? The measure of "effectiveness" isn't whether the best and most capable teacher can do it. It's whether *everyone* can.
New @nytimes piece ranks 30 education interventions on both effectiveness & costs. For me, the key takeaway is NOT about what academics (including myself) rated as most effective or least costly. It is about the decision making process districts use. 🧵 nytimes.com/2026/09/28/upsho…

103-year-old Captain Eugeniusz Niedzielski, one of the oldest Polish veterans living in the United Kingdom, laid a wreath for his fallen brothers in arms - the 22,000 Polish officers brutally murdered in Katyń by the Soviet NKVD. It was perhaps the most moving moment of the ceremony. On the 50th anniversary of the unveiling of the Katyń Memorial at Gunnersbury Cemetery in London, Poles living in the UK gathered to honour the victims of the Katyń Massacre. [*]

On the 50th anniversary of the unveiling of the Katyń Memorial at Gunnersbury Cemetery in London, Poles living in the UK gathered to honour the victims of the Katyń Massacre. Among those present were representatives of the Polish Senate, the Polish diplomatic corps, the military, scouts, Polish Saturday schools, Polonia organisations, and other distinguished guests, who laid wreaths in tribute. This solemn ceremony honoured the 22,000 Polish officers and members of the intelligentsia brutally murdered by the Soviet NKVD. The Katyń crime has never been brought to justice. The event was organised by the Stowarzyszenie Kombatantów Polskich w Wielkiej Brytanii (Polish Ex-Combatant Association in the UK).
