Among the thorns? I *did* get my infographic —  mostly info, not much graphic but telling my self that is not a priority and to let it go… though… realizing linking to *it* and not the project itself  is pretty close to useless. I didn’t get to Geogebra.   I *will* on the morrow.  I need to […]

A site full of virtual manipulates, which seem to be javascript 😉 🙂   http://mathsbot.com/ Free, but not “OER.” The Open Education people seem to be mostly about Changing How Institutions Do THings.   Power In Numbers has been about curating and sharing OER for adult ed.   This is at such a smaller scale! I keep finding […]

Don’t drop that mic :)

I think I have a microphone that will get me good sound quality for the Camtasia stuff!  (Yes, geogebra, you’ve been back-burnered for a spell).   It’s not great yet but now it’s a matter of refining, not cringing when I hear the sibilances or sighing that the volume is 30% what it should be.   https://www.youtube.com/watch?v=D8vhO-6Blw8  […]

From my tweetworld:  I think this is an excellent idea:   present these potentially overwhelming streams of symbols in a way that helps the learner know what to look at.   (I also think we need to include practice reading stuff without that little crutch.) That said, it’s just a better-looking presentation of … symbols.   It doesn’t […]

Geogebra.   “Lists” are a lot like arrays, tho’ the first element is list(1) not zero; zero will get “undefined. No, I still have no idea how to actually SET THE STUPID X AXIS TO THE SIZE I WANT.   I mean, I know how to set it but it changes if I so much as move […]

D’oh… deciding not to devote a mess of time to GIMPing “additive inverse — I can do it later — but YAY for Youtube… John Barclay informs that I can grab number lines by tracing spreadsheet graphs.   Note to self:   This is great for your FSI presentation (“GIMP FOR PEOPLE WHO DON’T HAVE TIME TO […]

So… exponents and variables and … zero power.   It’s a “touch base on this” section in pre-Algebra, nothing huge or convoluted (and I don’t *think* negative powers). It just might stick.   Things squared?  Write it out as this times itself until you don’t have to.   Zero power?  write it out as base/base […]
