The Error of who, quien, which, cual, what, que?

Williams does a great job in this piece discussing the errors of written and spoken language.  I found it quite comical at times, namely when he was analyzing sample errors.  I could not stop thinking of many of the errors that my ELL students commit on a daily basis.  It is not that they don't care or are ignorant of the "Rules of English", it's that they haven't learned all (or many) of the rules and idiosyncrasies of English (or their first language).  They are simply trying to express their ideas, opinions and what they feel is the "right answer".  Their inability to write in "Perfect English" does not signify that they are ignorant of the rules or just don't care, they simply aren't as proficient in their second language as they could/will be someday.

The same can be said for many of our English-dominants students who may want to do well, but cannot articulate it as clearly as, say, Bartholomae or Elbow.  Their opinions, ideas and answers (wrong or right) need to be expressed. They deserve to have their voices heard regardless of their ability to speak "Proper English".
