Imagine the following scenario: You are teaching a course and give a writing assignment. With the deadline fast approaching, one student asks a classmate for a copy of her paper, makes a few revisions, and submits the assignment as his own original work. When you confront the student with evidence of plagiarism, he accepts responsibility for cheating. The second student, who provided the original paper, is shocked that she, too, would be accused of cheating. She simply e-mailed her friend a copy of her paper.
