The Khan Academy Experience, continued

I’m evaluated “OERs” — open educational resources — at oercommons.org.   It’s a pretty awesome site and idea — share good sites, and evaluate them and share the knowledge. I found a pretty nifty lesson on area and perimeter, and was pretty happy at how Sal Khan presented area with color pictures with tiles that […]

(yea, one of those F words…) It’s closing in on the end of the semester… it’s Saturday but no bicycle ride because it’s Illinois Marathon day. I didn’t go out and holler at runners, even (the route’s a few blocks away).    My attempt at an app… well, I abandoned hope of getting anything to […]

So, after doing the conceptual framework building of recursions… today we went over the text example that is essentially a template for our lab.  (edit in hindsight:  this was posted days after I typed it.  We had class on Thursday, not Easter Sunday ;)) Had he mentioned this, I would have spent considerably less time […]

I’ll see at two when answers get posted which ones I missed… will they be the ones I wasn’t sure of?  Yes, I was thinking of recursiveness on the ride home, too 😉   More, though, of the niftiness of a teacher working to make challenging content accessible; not easier in the long run, but […]

More o’ that concept stuff…

So today’s topic was “recursion” — and he walked us through really.  simple.   examples.   of it.    I stumbled over recursion in my JavaScript class, when I wanted to display exponents and was googling for tips for putting that in, in animated form.   I’m curious as to how challenging my uniquely wired […]

Random nonsense

Just another example of “real world” word problems that have nothing to do with the real world, and are actually and obviously convoluted wrappings of algebra in words.    I fully understand the value of making the connection between linear equations and real world situations.  However, this one leaves students cold and nauseous. Been too […]
