Time after time one student turns to another to ask, say, how to pull up a file or italicize. I don't want to tout non-linear logic as an earthshattering development. Regardless, it is here and we need to help students differentiate between skillful and unskillful use. I believe the ability to incorporate text, graphics, sound, and video calls for a deepening of authorial choice and skill. Teaching students to integrate media skillfully is teaching them to write.
Hurried writing is bad writing.
So much e-mail, written hurriedly, is garbage. I don't disagree. As a writing instructor, one of my tasks is slowing students down. On paper or screen, I try to help them think more carefully.
