Question

Quizplus · Accepted Answer

Asking students to write only their social security number or some other code on later tests can help the professor avoid being influenced by his first impressions about individual students' performance. By removing the students' names from the test, the professor can grade more objectively, without any biases or preconceived notions about individual students.
