As a teacher, this was always a tough thing to hear. You pour yourself into a lesson and then get to the assignment and a kid asks, “How long does this need to be?”
I hear this and in my mind I hear an underlying second question, “What’s the least amount I need to do to get this done.”
My response wasn’t really liked, but it was honest:
“It needs to be as long as it needs to be. I’ve read 3 brilliant sentences that said all that was needed to be said. I’ve read three sentences that told me nothing. I’ve read paragraphs that are eloquent and beautifully written, which cover everything needed. I’ve read entire essays that are crap. The length isn’t important, the quality and thoroughness of the writing is.”
If what’s being assessed is an essay, a response should be essay length in an essay format. Beyond that, does length of a response really matter? Does the format make a difference if the message is well conveyed? Does your next assignment require a minimum length, or does it require a response that clearly demonstrates understanding?
