Do you still use the red pen to mark your students’ writing? Apparently, this type of feedback is seen as more aggressive and less helpful. This article suggests an excellent alternative: making video comments. You can show the students’ work on the screen, or your face, or both – and the feedback will be much more effective (and take you less time than writing out all the corrections). For more examples and a set of guidelines check the website mentioned in the article. I am definitely going to try something along these lines (once I get myself a proper mike!).
