Break over!

June 19, 2017

(When I was a lifeguard at little apartment pools, we called the “adult swims” what they really were — breaks for the kids to get out of the water.   We didn’t call them religiously on the hour — and the kiddos usually figured out that they’d get called if they started getting cranky with […]

VIsuals! Visuals!

Last night I chatted with a friend who’s a graphic designer specializing in educational materials.   She loved programming but … math.   She had said that when she sees a recipe and it calls for 1/3 or 2/3 … what??? I had been explaining to her the visual I need for my lessons:   […]

Need to get away from twitter which has a mess of stuff from another open education summit.  Sour grapes. I did the next two (now down to 16 lessons) ALEKS lessons … the figuring out angles and sides of a triangle with laws of cosines and sines.    Talk about exercises in precise attention to […]

The analogy of the day:   “Tricks” such as arbitrary memorized “scaffolds” and […]

I sipped wine and skimmed the last 5 years of blogging. Alas, it didn’t really help with my “what was I doing, when?”  as much as I’d hoped.   I did find the elusive video of “counting stick multiplication” per https://www.youtube.com/watch?v=yXdHGBfoqfw  (I hadn’t been able to find it from memory). … and oh, my, I miss […]

Decimation

Decimation is literally losing 1 in 10 people;   if I remember correctly it was a strategy used for discipline in somebody’s army.   The 90% remaining would buck up and behave, in abject fear. Most usages these days involve losing more than 10%, but I’m thinking our current college situation is similar.   http://www.news-gazette.com/news/local/2016-06-28/talent-learning.html    […]
