By not reflecting on grading practices, a teacher may inadvertently assign scores to students in a manner that does not align with their beliefs about what that grade should represent.
When grading assignments in the past, I always focused on wanting to score each student fairly. However, I stumble when students can get part of an answer right and then try to figure how many points a question is worth. As I go through a stack of papers, I notice issues and want to go back through and make sure each assignment is scored correctly. It becomes time consuming and confusing because each student can answer in their own way. I know that it will become easier for me, but right now I feel the need to have a strict belief on what grades represent and stick with it.
