Maybe you could look at Helium [ http://www.cs.uu.nl/wiki/bin/view/Helium/WebHome].
From what I understand, it's a subset of Haskell specially designed for teaching. I heard that it provides also very good error messages and hints about typical errors.

One question that I have been grappling with in this regard: How to run ghc in lightweight/beginner mode?
2 examples of what I mean:
1. gofer used to come with an alternative standard prelude -- 'simple.pre' Using this, gofer would show many of the type-class based errors as simple (non-type-class based) errors. This was very useful for us teachers to help noobs start off without intimidating them. 2. Racket comes with a couple of levels. The easier numbers were not completely consistent with scheme semantics, but was gentle to beginners
Any thoughts/inputs on this will be welcomed
