Every college syllabus should include these graphs.
Use AI for homework, you will get it done faster and get a higher grade, and then get crushed on the exam.

On this day in 1983, Joe Delaney died a hero attempting to save three children from drowning. Today and always, we honor his memory and sacrifice.

An important business reminder when you are dealing with AI generated content.

2. Stop explaining yourself to people who are committed to misunderstanding you.
You could have a PowerPoint, data, witnesses.
They'll still twist your words.
Your energy is finite. Spend it on people who listen, not people who've already decided who you are.

Great “trick” to get kids to learn
Two groups read the same passage.
* Group A was told they'd be tested.
* Group B was told they'd have to teach it to another student.
Nobody actually taught anything.
They were just told they’d have to teach.
Group B crushed it.
Better recall.
Better organization.
Advantage concentrated on main points.
So just believing they'd have to teach changed how they studied.
The researchers' line that stuck with me: students have effective study strategies they simply don't use unless prodded to.
So our kids already know how to learn well.
They just don't do it when they're told to study for a test. The test framing makes them passive.
While teaching makes them active.
At @ForgePrep, the highest level of mastery students can demonstrate is teaching another students to competence. It’s part of why we have Montessori mixed age classes as this creates more opportunities for this type of teaching

2 weeks without smartphone internet significantly improved sustained attention.
The effects were similar to being a decade younger.

Ave person checks their phone 186x a day. That's an interruption every 5 min.
This shrinks the brain, causing lost capacity for deep reasoning and sustained thought.
Deep focus strengths neural networks for complex thought.

"A new study reveals that young children learn letters and word structures more effectively through handwriting than typing.
Researchers taught 5- to 6-year-olds unfamiliar letters and pseudowords using either manual writing or keyboards.
Those who practiced by hand performed significantly better on tests of recognition, writing, and pronunciation, especially with unfamiliar word sequences. The study highlights the importance of graphomotor movements in developing reading and writing skills and suggests handwriting should remain central in early literacy education.
Key Facts:
- Handwriting Advantage: Children who practiced manually learned letters and pseudowords better than those using keyboards.
- Motor Skills Matter: Graphomotor movements help imprint letter shapes and word structures into memory.
- Free Writing Boost: Among handwriting groups, free copying (without guides) led to the strongest learning outcomes."

To be clear, about ed tech:
--I think teachers should have a computer in the classroom and way to show images and videos, if they choose to.
--I think @khanacademy has proven its worth, abundantly. I wish it could be offered on a dedicated device, with no distractions.
--In my several posts about ed tech, teachers often add comments. They rarely praise or defend ed tech.
--I think schools should have a computer room (as at the Waldorf schools that some tech execs seek out for the low-tech classrooms). Students need to learn to use computers and the internet.
--The most damaging mistake seems to have been the 1:1 devices -- putting a Chromebook or tablet on each student's desk. As a UNESCO report said in 2023, the distraction effects seem to exceed whatever benefits a few of the apps might have:
unesco.org/gem-report/en/pub…
--I don't doubt that some apps which gamify learning have been proven to produce faster or better learning than older methods. BUT: if you gamify a third of the school day, the dopamine effects would cause the other 2/3 to seem more boring. So the net effect in a real classroom may be negative even if some apps showed consistent benefits in controlled tests.
--The big question we need answered is: does giving each student their own device, to use during much of the school day, end up promoting or interfering with education over the course of a year? Horvath's graph suggests that in real classrooms, it interferes.
--Putting devices on every student's desk seems to be the second giant uncontrolled experiment that the tech giants ran on our children, without our informed consent. (Smartphones and social media was the first.) They are already starting up the next one: chatbots for kids, and these will be pushed into schools too despite the already obvious harms.

He knew he might never walk off that plane… but he still chose to fight.
When terrorists hijacked United Airlines Flight 93 on the morning of 9/11, 32-year-old Todd Beamer didn’t freeze. He didn’t surrender. He picked up an Airfone and spoke to operator Lisa Jefferson — calmly, bravely — in the final minutes of his life.
With his wife carrying their unborn child at home, Todd’s voice shook as he said:
“If I don’t make it, please call my family and let them know how much I love them.”
He could have spent his last moments in fear.
Instead, he chose courage.
Todd and a group of passengers made a plan — to rush the hijackers and take back control. Lisa quietly stayed on the line, listening as he rallied the others with one final, unforgettable phrase:
“Let’s roll.”
Their fight forced the plane down in a Pennsylvania field — away from the U.S. Capitol, away from thousands of innocent lives.
Todd Beamer didn’t live to see his baby born. His children will grow up knowing their father died a hero — protecting people he would never meet.
Some heroes wear uniforms.
Some simply refuse to give in to fear.
And the world is safer because of them.
NEVER FORGET THIS MAN

Social psychologist @JonHaidt: We’re getting young men addicted to video games, porn, gambling, investing, vaping—and then act surprised that they’re not transitioning into adulthood.
It was “open season on their dopamine systems—and it was hugely lucrative.”

A big thank-you to our Robotics teacher, Mark Rocheleau, for an engaging presentation on the benefits of interactive panels in the classroom. His passion for innovation and hands-on learning continues to inspire! Well done!
