When I read this I just shook my head - rather than teach students - make the tests easier. I can imagine the difficulty of reading and grading essays that are basically texting.
But I have to admit that I have grown too reliant on spell checkers. Even though as I write (type) the mis-spelled word, I recognize the error - but still rely on the spell checker to catch it, and depending on the program, to also correct it.
Spell checking is good news for words like "believed" - but not good for words like "quiet." I often write "quite" when I mean "quiet." It is one of those situations where the spell checker doesn't bail me out. It can render a thought incomprehensible.
I guess my point would be that ignoring spelling as an element of an essay composition and comprehension is misdirected. Making it easier doesn't translate to a quality essay. Even using a computer - the writer still has to know that the word used is the word intended.
Shouldn't at one point in a person's life he or she be held accountable to convey a comprehensible communication; and therefore, not rely on the reader to discern what the writer must (or should) have intended?
