If “punishment” is part of your pedagogy, you should just walk away quietly from work as an educator, and if you don’t, then you should be dragged away making whatever noise you will.

“Not all causation is linear...” yeah that seems right.

Be a skeptic, but not an obstructionist... there is a difference.

One of the best parts of being a skeptic is the look of disappointment on a conspiracy theorist’s face when you suggest an explanation informed by Occam.

I’m suspicious of all proposals or models with alliterate summaries.

I’m at the end of my 38th year working in education. I’m still fascinated & curious about the craft & have more questions than when I started.

The one thing I do know, however, is that *everything* written and said about teachers (the good and the bad) is true... for some.

"Learning doesn't consist in being an empty receptacle." - Mortimer Alder

No matter how much you like a particular teaching strategy, it isn't always appropriate and some students will stop engaging if you always use it.

Just because you have a strong opinion, I’m not obligated to take it seriously.

Did teachers react to the introduction of slide rules in the same way they reacted to calculators?

"Power knows the truth already, and is busy concealing it" -Noam Chomsky

When chalkboards were introduced at Yale in 1837, students objected as they thought if they didn't memorize it, then they weren't really learning.

“Throwing money” at a problem and “fully funding” systems are not the same.

Whenever I interview for a job, I make a joke in the first minute. The response of the group tells me to either “answer quickly and get out of here" or “give honest and complete answers.”

If you are a teacher who can be replaced by a video, you should be." Yeah, I can't argue against that one. #teaching #highschool #highered

The best #STEM #education is grounded in "curiosity, experimenting, iterative synthesizing, analyzing problem solutions, inventing." I think this list is incomplete (critical thinking belongs there), but the list is certainly different from the skills that I see focusing much of it.

So much #learning is lost in the quest for grades. #teaching #education #educhat #edchat #highered #highschool

Do you want your course to expand access to your field of study or do you want to pose a barrier?

There are reasons for framing and teaching courses as each, but don't confuse the two and don't mislead your students. Also, realize very few courses as barriers can be justified.

Grading on a bell curve? There are several reasons to do so, but none are grounded in learning. #eduction #highschool #highereducation #Assessment

Francis Galton, one of the first "data scientists" was an ardent eugenicist. Some groups were genetically superior, he claimed, and he found the data to prove it. Politics and bias have always been deeply embedded in the questions that motivate data, its collection, and interpretation.
