New Year’s REsolutions

August 23, 2014


One of my recurring ones is: keep Resource Room better updated. Welp, I at least knocked one piece of that off the list: I uploaded “Drill Bits” so that anybody can pull it down now. “Drill Bits” was a product I sold when I did that on the website. It’s a rather vast collection of […]

udacity fading?

August 22, 2014


I read on the discussion that Udacity doesn’t offer certificates for its “visualizing algebra” course now… so I wonder if it’s going to just … fade … away.   Sad.   This online stuff is new enough that in my not so humble opinion, it’s worth exploring different variations…      It’s Friday 🙂 

Ruminations on administrations.

The puzzle has a six-ring target with assorted numbers that you’d score for hitting it, which I don’t recall. (I think […]

Those ever changing rules

August 15, 2014


Nifty keen-o — will let you download an article listing some of the big conceptual confounders.   It has been really helpful for me to begin talking about integers with the idea that we may be uprooting some well-entrenched models of what math means:   that “plus” always means add and make a number bigger.

… but no, things didn’t improve.  However, my computer at work has not been tainted with updates and … things seem to be actually working.   I even got things like answers from StackOverflow — though the advice was to update everything and … no, that doesn’t work… and my subsequent question didn’t get answers.  […]
