Just stop

If we're talking about technology in a math classroom.  You know, calculators, computers, Wolfram Alpha, all that cool stuff.  And you say "Well if your calculator runs out of batteries..."  or "If you don't have an internet connection..." or something in that vein.  Then I would consider our conversation to be over.  And I would safely say that you're not thinking very carefully about the issues surrounding technology and learning.

It might be that you just need more time.  And that you haven't thought carefully enough yet.  Or you live in California and you've given in to the demands of the CST's.

But I can't believe that you've really thought carefully about your own life and how you do math.  Or watched someone under the age of 25 and how they interact with technology.  

More on what careful thinking on these topics looks like later...
