Sigh. Earlier in the semester I had a student plagiarize a 400 word reading response paper by copying and pasting whole sections of an article the student found online. When confronted, he accepted responsibility immediately and seemed contrite. We had a serious talk and he received a zero on the assignment. Fast forward two months and he just did the same thing again, this time copying and pasting all but three sentences in his reading response essay. An essay worth a grand total of 2% of his final grade. This is frustrating (not quite as frustrating as the situation my colleague is currently dealing with, wherein one of her students plagiarized an article she wrote, but still).
So now we are going through the honor council process. I am a new faculty member here, so the process is new to me. We'll see how this unfolds.
