For those unfamiliar with the buy it for life movement, it’s a grassroots rebellion against a culture and an economy designed to be disposable. Adherents look for items that will stand the test of time, even if they cost more up-front.

It's astonishing to witness the improvement in public education--reading, math, attendance, grad rates--in Alabama, Louisiana and Mississippi. But we're busy fighting culture wars rather than scaling up what these three states have done. Please do read: www.nytimes.com/2026/02/09/o...

I love the word "schoolman" because it's such a great distillation of a particular type of person in and around education. Not all schoolmen are men. Most are. Not all schoolmen work in education - a sizable chunk don't.

Funny how from 1990 until about 2015, test outcomes for American K-12 students generally improved, and yet so few seem to care about the lessons from that era.

The machines ask questions of a student. If a correct answer is provided the machine offers new information. If a wrong answer is given the machine moves back to simpler material… pupils will learn in 1 hour what it takes a human teacher a whole day to teach them in laborious classroom instruction!

This story was produced by the Associated Press and reprinted with permission. SAN ANTONIO — Sandra Mosqueda watched with an amused smile as her 2-year-old son, Atreus, began sweeping the floor with a miniature mop. Atreus is part of the inaugural class of infants and toddlers receiving free preschool in a citywide program in San Antonio, Texas. It's something his mother doesn’t take for granted. As a child, she herself wasn't able to start preschool this young. In the case of her two older boys — now in first grade and kindergarten — the free preschool set them up for success in elementary school.
