I conducted a survey of 26 students to find out how they felt about getting red marks, which indicated grammar mistakes, on their writing assignments.  I was motivated to do this after some colleagues had told me students get upset or dejected when they see these, so they only marked a few mistakes, and one even changed to a different color, thinking that, like her, students associated red marks with something negative.

Three types of marks on students papers

When I give students feedback on their writing assignments, I want them to notice three things:

1. Good writing points.  These are ideas, details, examples, expressions, sentence styles, grammar that they did well.  I underline these in GREEN to indicate good.  (See Students’ Positive Responses to this Teacher Technique  for more details.)
2. Weak grammar points.  These are grammar mistakes or wordings that they should revise to improve their papers.  I try to indicate these in a way that seem like a puzzle that can be stimulating for students to discover. I use RED to indicate these.  (See Most Effective Technique for Marking Grammar on Essays to Develop Self-Editing Skills  for more details.)
3. Places to improve content.  These are places where students could improve their papers by adding details and/or including examples. I use BLUE to indicate these.    (See “Wow” is not Necessarily the Goal in Students’ Essays and The Huge Advantage International Student Writers Have Over Their American Classmates for more details.)

The survey question to students: If you could only have one type of mark on your papers, which one would you choose?

If those colleagues who thought students were upset by red marks (grammar mistakes) were right, then it would seem that the students would not choose that option, and in fact, probably prefer the Green (good parts) option.   Spoiler Alert: that didn’t happen.
