My son tells stories about a company he associates with whose leaders respond to failures with, “yeah, we own that one,” but they never fixes the problems. I now listen for it. I conclude this is a common response of those who have no capacity to fix problems.

“Tell me what I can do to help” always sounds dismissive when coming from colleagues and leaders. I interpret it as “I’m not going to understand this well enough to see my role.” If it fails, the leader can claim, "I would have helped but you did not ask" or "I did everythng they asked."

Remember rationale thought? Yeah, that was great.

Don’t blame a conspiracy when incompetence suffices.

If your statistical evidence is simple, you misunderstand the problem... and statistics.

So much evidence that educational policy makers have WEIRD and wacky views of teaching and learning.

When leaders have no idea what potential is in their organization, those who can make the greatest contribution withdraw from the work... some leave, some “do their job” but nothing more, some contribute but their ideas are dismissed by those leaders.

Fluid intelligence is the ability to solve new problems. I'm not so sure what is happening in schools today increases this capacity.

No computer is ever going to ask a new, reasonable question. It takes trained people to do that. - Grace Hooper

You know the problem with math is you have to get the same answer as everyone else... and in some applications (think designing bridges), you have to get the same answer that nature would if it did math.

Another idea that makes data driven folks respond with a blank stare: null hypothesis.

I recall really enjoying the Man A Course of Study lessons as a student. I’ve been a fan of Bruner and his ideas about teaching and learning for decades. It wasn’t until about 10 years ago that I realized who led MACOS.

Mastery learning... when you stay on it until you get it... is based on the assumption that the path in the curriculum is *the* path and that the measures of mastery are valid and reliable. I’m not so sure those assumptions are correct.

Textbooks are designed to remove the difficulty of learning... I don’t think they have helped.

Why, yes, we all do have calculators in our pockets.

Your data may be sound, but your interpretation may not.

More than any other single invention, writing has transformed human consciousness. -Walter Ong

Most any teaching strategy can be effective for some purposes... it’s when we believe one strategy is effective for all purposes that we fail. #edchat #teaching #students #highschool

Knowing how to get very precise answers to calculations doesn’t mean you should... the meaning of the answer may get lost in the unnecessary precision.

So, if you report grades to 2 decimal points... e.g. 87.34, then you are saying your tests/ quizzes etc. are sufficient for you to discriminate 10,000 levels of performance.

Really?
