Translation through the iPad Viewer

One of the coolest apps I’ve seen for the iPad is WordLens, which will translate whatever text it sees through the camera viewer.  I didn’t demo it in class because each translation dictionary costs $5.  I bought the English/Spanish dictionary, but since I don’t speak Spanish, I can’t tell how well it is translating.  Nevertheless, here is a picture of the front page of today’s New York Times, and also one of how WordLens translated it (in real time, directly to the screen), when I hovered the iPad over it.

Definition of insanity...

is doing the same thing over and over again and expecting different results.

I wonder about this with respect to reteaching.  In one of the classes I'm observing, the students who do poorly on tests get pulled aside be to retaught the material, while the others do some sort of enrichment activity.  The students may have failed the test for a variety of reasons:  a bad day, absence from school beforehand, careless mistakes, or not understanding.  The reteaching is done in the same way that the original teaching was done, and does not seem to help the kids who tried but didn't get it the first time around.  This seems exactly the time to try something different, as you have proof that it didn't work the first time around...
