Here is a matrix by which you can categorise the comments you give when marking:
Make a tally chart with each of the six categories then go through a few pupils’ exercise books looking at your comments, considering which category they fit in and then add the tally to your chart.
Positive- specific and positive- developmental are the two types of comment that promote the best learning. How did you score?!
This exercise can be used as an ice-breaker in departmental meetings as a way to begin discussions about effective marking.
