What are student perceptions of my marking and feedback practice of summative assessment?

I am not really interested in the behaviour of the students per se, how much time they spend reading the marking for example, but rather, I want to examine my own practice and see how I can improve to better meet student needs. Therefore, I need to find out what their behaviours around marking are, so that I can unpick and critically reflect on how I can make changes.

Questions that might arise include: Does my marking serve a deeper purpose for students beyond getting a grade? Do I need to find ways to encourage greater engagement of students with my marking? Will I need to make fundamental practice changes to do this?
