When I talk to groups of students about the writing, I tell them that texting and chat rooms are killing our writing abilities. I tell them that even though Word is my passion in Office, and that I am even certified in it(2007), spell check will be the death of them. They should be the final proofreaders, when they have not had anyone else read over what is written. I also remind them that any errors or missused/misspelled words will cause their resumes to be thrown in the garbage.
I help the Campus Online Coordinator with the students who take onlne classes; I have seen about every class that is offered by our college. In orientation, I tell them that the instructors DO check how things are written in discussion, as well as assignments. Even after that, I still walk by and catch students not using any punctuation, no capitalization; I make those students stop and go back to correct those mistakes. I again emphasize that it DOES matter how you write, and that the instructors will not decipher the text chat talk.
