Just because you experienced it in school, does not mean every one did... or should... or even that you did it at all. Human memory is that bad.

asks "why were you late," you need to resign. If you are a principal who observers it, you must call the teacher out... yes... in front of students.

Yeah... if you attend the "advanced" training, please avoid asking the presenter to show how to do "stuff" done in the "basic" training.

I used to write notes on paper in meetings in my own β€œscrawly” short-hand. I claim it was an analog encryption method.

Is delivering content and tracking views (which any worthy LMS can do well) teaching?

You don’t get #students to understand ideas by learning definitions of more terms.

What if education was based on building what doesn’t yet exist?

I just read a piece about how #OER textbooks are a "disruptive innovation." Sure, they might interfere with textbook profits (if we can continue to increase adoption), but I think it is disingenuous to suggest they will disrupt #education. #teaching #school #highered

Knowing β€œthings” is of limited use... knowing how things interact... that is useful.

When ideas become popular, they are appropriated by everyone for everything that makes β€˜em vacuous. I once heard (seriously), β€œI want my students to learn, so my lectures are the real β€˜student-centered’ teaching.” This was from a 5th grade teacher... who lectured!

Learning styles don’t exist, but teaching styles definitely do.

If you are ignoring theory, you aren’t really being data-driven.

Taylorism was *not* designed for education.

There is a difference between what we β€œswallow” when learning and what we β€œassimilate” when learning. Schools have abandoned one.

β€œIf represented as a graph, science approaches the real world like an asymptote.” Yup, pretty much.

When it is well done, science blurs reality by asking more questions with each one it answers.

A former colleague used to tell the story of getting pulled over for speeding on the way to work. The officer said, β€œIf you give me a good excuse, I won’t write the speeding ticket.” He replied, β€œI’m a teacher and I have to make copies for my students.” He did not get the ticket.

"Why don't you just have AI summarize it?"

Because I am interested in making sense of it, not just having a summary .

Epistemology is deeply important to educators. It allows them to evaluate practices, adopt and adapt those that are useful, discard those no longer useful, and otherwise refine their craft.

"Action without faith is misguided." Really? I can't imagine a statement that is more misguided than that one.
