Assuming that specific criteria are used when grading, then evaluating student work can:
• Encourage a link between course goals and assignments.
• Become a part of the motivational structure of the classroom
• Encourage a professional attitude towards learning.
• Provide diagnostic information to both teacher and students, by clarifying exactly what the student is or is not being rewarded for
• Reduce the number of questions students might have about where their grades came from
• Be a low-hostility approach to discussions about grades, and can enhance/guide dialogue among students and faculty about their work.
Conversely, NOT using specific criteria for evaluation can prevent some, if not all, of the above from happening.
