I did it - I tattled.
I consulted one of my former classmates that is now in the PhD program who will be a professor one day. I asked him since he kind of has the perspective of an instructor. He said all the same things that you guys did. So the way I see it, you can all start putting "PhD" after your name if you want.
This is what I wrote:
Dr. A -
After much thought and counsel with others, I have decided that I really need to tell you that I am almost 100% sure that one of my classmates has been plagiarizing some of her question responses. You may already be aware of the situation, but just for the sake of the integrity of the program I feel the need to speak up.
The only reason I noticed is because one of her responses made absolutely no sense. It was not written in complete sentences - it was almost as if it was just a bunch of bulleted statements copied and pasted together. Well, I copied and pasted her response into google and discovered that it had indeed been bulleted statements from the City of Pasadena's HR website.
She is a group member in another one of my classes and I am very familiar with her style of writing, so when I read another of her responses this past module, I felt sure that she had done it again. She had.
If you would like more specific information (such as her name and examples), please let me know. I really hesitated with whether or not to "tattle" on her, but at the end of the day, I feel that what she is doing is unethical and wrong. I know how hard you work and the thoughtfulness that went into the creation of this program, and I think her actions are an insult to everything it stands for.
I'll let you know if I hear back!
