Mark Twain probably didn't actually say this, but my job title is literally Director of Continuous Improvement, so I at least endorse the sentiment.

Dark olive quote graphic with oversized pale yellow quotation marks in the corners. Centered text reads “MARK TWAIN” and “Continuous improvement is better than delayed perfection.”

The Luddites were not opposed to technology. They were opposed to the crap quality linens the new technology produced. As an educator, I’m not opposed to AI. I am opposed to the crap instruction our elementary students are getting from AI. duanehabecker.substa...

Open book spread with an old wooden loom on the left and a desk with books, a lamp, a globe, and geometric shapes on the right, connected by flowing golden threads. Large text across the bottom reads “PROUD TO BE A LUDDITE.”

As I see it, the diagram of the gears seems to be suggesting that when we try to combine curriculum, leadership, and professional learning communities, then the gears won't work and the system comes to a standstill. Can we just fix the image please?

Three gears arranged too closely together that they will not actually spin. One gear is curriculum and assessment. The second gear is instructional leadership. Third gear is professional learning communities. As I see it, the diagram of the gears is unwittingly suggesting that when we try to combine curriculum leadership and professional learning communities, then there is gridlock and the gears won't work.

The classic “which cellphone plan is the better deal” problem has a real life update. gizmodo.com/ultrahum...

Screenshot that says…
The Ring Pro’s biggest hurdle is going to come from its steep entry-level cost. It retails for $479 with its charging case. The case is also sold separately for $100. The Oura Ring 4 starts at $349, but can be as pricey as $499 depending on what finish you choose. The Oura Ring 4 also requires a monthly subscription of $5.99, which amounts to about $70 per year.

Is it okay that I didn’t immediately know what bowdlerize means? Sure. Is it okay that I needed to look it up? Absolutely. But don’t freaking tell me bowdlerize means to expurgate. What. The. Hell. Is. Expurgate?

A screenshot of a news article using the word bowdlerize. I looked it up and learned that it means expurgate. What the hell does expurgate even mean?

GH Hardy famously (& proudly) wrote, “No discovery of mine has made, or is likely to make…the least difference to the amenity of the world.” Decades after his death his work now underpins online banking, digital communication, and understanding the complex shapes of proteins.
