#iteachmath — Public Fediverse posts

Instead of taking siloed discipline specific introductory science courses, I think high school and college freshmen should be required to take a nonspecific course in precisely what science is and, more importantly, what it is not, with a heavy emphasis on critical thinking. It would be taught by non-research faculty dedicated to this content, from all STEM departments. Save the discipline specific courses for the majors. #ITeachPhysics #ITeachMath #AcademicChatter

I recently heard an episode of RadioLab about the Swedish Navy. It inspired me to think deeply about the Fish Farts of education.

My TWO steps for creating a classroom culture that embraces productive struggle.
Step 1: Teach wide math, not narrow math.
Step 2: Explore-first instructional strategies

Hey, it's about to be a new school year... let's revive :) For 3 weeks I did aonce a week blog post for adult ed that I shared w/ the Adult Numeracy Network (which has their own online discussion)... but I'm thinking of being a wild crossposter. Today's goal: figure out the routine for that.
ICYMI here's how to make good number lines really quickly with PowerPoint: https://youtu.be/Rm1o7SWzoa4?si=-S5HwbUSRoS4MIb2 SELF: include accessibility info into the routine.

Being a content-specific Instructional Coach requires a deep knowledge of adult learning IN ADDITION to the content and its instruction. I am a lover of Andragogy and Transformative Learning.

It has been a while since I've last blogged. This one was inspired by a Popular Science article about placebo buttons.

#mtbos #iteachmath LOL Karen Campe I did a blog post too.... towards a more specific situation and audience, and ... shorter b/c I want to make a bunch of them. https://resourceroomblog.wordpress.com/2026/06/29/numeracy-post/
It's talking about the manipulatives I have just lyin' around in the tutoring center. Somebody on LinkedIn posted about it being bad to have 'em all tucked in drawers (but I never did find the actual post), which made me feel justified in being a person who Forgets to Put Things Away.
The next installment will be handouts and visuals .... but the ONE AFTER THAT will be about the hidden conceps that if I take time to help my learners build, enables pretty ferocious progress.
Okay, my pre-algebra to pre-calculus person is not typical (like those diet ads, right?) but it really was about "this is how you need to work with these problems."

And a couple from Cecil Hunt's My Favourite Howlers (1951) https://archive.org/details/myfavouritehowle0000ceci/page/44/mode/2up?q=polygon

'A polygon is a man with more than one wife, preferably living'

'A polygon with seven sides is called a hooligan'

A couple of mathematical howlers from Just My Typo compiled by Drummond Moir (2012):

'A triangle which has an angle of 135 degrees is called an obscene angle.'

'A polygon is a man who has many wives.'
