Yes and no... not to make it easier, per se, but to make it more like math. I built CodeWorld, not to teach Haskell, but to teach middle school math! So the main motivation was to make it easier for students to see the connection between the functions they write here, and the f(x,y) that they see in algebra.

That said, uncurrying functions also has a huge benefit when it comes to understanding error messages in Haskell. I love currying in Haskell, and it's very powerful... but it's one of the features that sometimes leads to obscure or misleading errors -- especially when you leave out type signatures... which I do for the first month or two.
