Do you still use a red pen?

I was following a link from one of my subscription emails to a Forum Debate on tes.co.uk.

The question being discussed is:

Do you still use a red pen?

Here are a few of the comments posted in reply to this question from tes.co.uu:

We have to mark in green because, apparantly, the children get upset if their work has red marking on it! Now green is the new red!  Having marked in all the other colours of the rainbow over the years, we now HAVE to mark in red... I mark in black or blue for positive comments and in red to highlight the mistakes the students makes and my feedback, otherwise they would not take notice of what  they have done wrong and why. I mark in both green and red. The more the green the better the work, the more the red, the more mistakes they have made. I think its right to highlight the negative elements so that they know what to fix for next time. The worst thing I think is when kids don't review their homework and this is likely if the marking is monotone and uninteresting ... http://www.eltvista.com/2011/07/using-correction-codes-saving-your-students-from-going-down-with-their-slips-in-a-sea-of-red-ink/ What about you?  Do you use a particular pen for marking students' written work?  Do you think it makes a difference? We will come back to the subject of correcting written work in another post! http://www.getfreeimage.com/image/15/check-and-cross-marks-icon
