As a high school math tutor for one of the large national test prep companies, I can say with complete certainty that even when the "box" is replaced with a variable name, students still do this. I find that it's not so much that they don't grasp that the = symbol means equality as much as that they don't realize what equality means.

If I give a problem like:

f(x) = 2x + 7
g(x) = sqrt( f(x) )*5

Many students can solve this problem; a good portion of them just understand "oh, I do a substitution" - they don't understand fully that the equality of a variable with some expression is WHY their answer is correct. Similarly, something like: 3/15 = x/225 Most students get thsi right; "oh, I just cross-multiply" - but they don't understand WHY cross-multiplication is the correct thing to do. Teachers need to start teaching real math in addition to problem solving methods and heuristics.

Brawl will feature cooperative gameplay in its adventure mode (as previously discussed on Slashdot), today's Smash Bros. Dojo blog entry reveals that in an unprecedented (but highly anticipated, discussed and predicted) move, Sega's very own Sonic the Hedgehog will be a playable character in the new Wii title, due to hit shelves before Christmas this year."
