Failed at “turn off the INternet and make stuff” this a.m. and went out and rode the bike fiercely at lunch (having had *coffee,* not tea) and tried to condense the looong drive “psych yourself into really making this count” talk that worked for the presentation into half an hour. I returned and successfully, quickly […]

Yes, some folks are getting on the Withdrawal boat… but if it’s from our newly designed math courses, they get to get right back on the same course at midterm, since they’ve pretty much gone to quarters for the algebra courses. I almost kinda wish they would do the same for PRe-Algebra, given the chances […]

Nifty keen-o — http://www.nctm.org/publications/article.aspx?id=42799 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.

I’ve spent my week bike-camping with GITAP folks, and now it is SUmmer Session. Happily, there’s nothing like a week sleeping in a tent to make the 7:30 arrival time (the price of the 4-day work week) an easy adjustment. So, 7.25 work-weeks remaining in which to produce Working Stuff For The Transitions Course. […]

… I showed one of the videos to a math class. SOme of ’em thought there were too many sound effects 😉 That would be the exploding noises I made when positive and negative canceled each other out… and after the singing, during which I blushed, I was asked if I were the narrator… Basically […]

… okay, the audio isn’t right yet, but I’ve got the “subtracting” rough draft. Want to get times and division (which are so much simpler), but In the Meantime, Fractions are calling ’cause I’m doing a presentation 9/20 and 9/21. I’m more than a little curious as to whether it’ll get better than previous effort […]

… tho’ I am thinking of sticking to my site after putting the first handful up. Introducing positive and negative integers http://www.youtube.com/watch?v=2OPANV75W-A Adding same signed integers – http://www.youtube.com/watch?v=IkV-dHnDNAU Adding integers of different signs http://www.youtube.com/watch?v=eT1CT4zr3i4

That’s when you know a chunk of software was done by Not Too Many People. I guess I am just supposed to INFER COSMICALLY how to add audio on top of my camtasia, which I recorded without the mic working, but didn’t discover ’til after it was produced. Well, I should be able to edit, […]

Seems “filezilla” doesn’t do “refresh” so even if I find those files, I have to close and open to actually upload them. I dunnit 🙂 http://www.resourceroom.net/math/absolutevaluebasics/absolutevaluebasics.html Today had more than one fortuitous coincidence — something led me to click something that revealed my “membership” in youtube and that weird username, which rather shortens the steps […]

So! I keep forgetting how dysfuncktional the file management is with Camtasia. I made the project and “produced” it… but OOPS!!!! I forgot to … well, I can’t quite remember what it was I was supposed to do to keep it from being saved…. where? NO, we’re sorry, you can’t find it — there’s no […]
