“nix the tricks” — how do we define trick?

July 24, 2017

I subscribed to MooMooMath and got an update that included this lesson on binomial expansion — raising binomials to assorted powers .    Linking to the one with the title including Pascal’s Triangle 🙂 Since ALEKS doesn’t include it, it doesn’t pertain directly to my life but the “what parts of ‘algebra’ should be required?”  is […]

The BEarded Math Man is posting some videos and … oh, Sal Khan’s got nothin’ on him : )   “Binomial reproduction” is one approach to factoring, with the analogy to “who’s the father?”  to figure out “where did this come from?”   If I were an adolescent I’d be luvvin’ it.   (Now, it […]

I really do oft reflect happily about our Math courses being taught for understanding, and speculate that I’d find another job if they weren’t. Summer courses… ugh.   Tech math so they’re allowed to use calculators for everything, including algebra problems like z/2 – 2/3 = -1/3z + 1/6 .   No, there’s no context […]

29 degrees and not much wind at all … and I got out a little early.   I could hear talk and laughter from one early-party group this “Unofficial Saint Patrick’s Day.” Imagining having funding. Imagining organizing (!yes, I think crazy thoughts on bike rides) the Urbana-Champaign node of OER innovations.  The technology and its […]

“When I make my own…”

I was helping a guy with the Connect lesson where they’re learning about figuring out scaled models.   They like to throw in “real world stuff that twists things” — so they talk about where “3/4” scale actually means 3/4 inches stands for one foot.   It’s a pretty neat exploration. Still, lots of them […]

I’m at the part where it’s time to shift from “oh! the potential!” to “LEt’s start making the deliverable.” I’m in Canvas building a quiz question.   ACCESSIBILITY.    Cognitive accessibility:   need that “onboarding” thing per Nir Eyal’s book so the intro is short and … I think optional.   Nobody reads the first […]

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    […]
