I like Peer 3 most. The peer gave me pretty constructive feedback including good points (compliments) and bad points (request for improvement).
I like the way she commented directly on my idea arrangement: “The answers were well put together, and the ideas were logical, clear, and easy to follow.” Besides, she made some contribution of thought to which points should be improved: conclusion and some mistakes of grammar & style. However, I think the feedback would have been softer if she had used “small mistakes” instead of “careless mistakes” and “could or should” instead of “need to” implying that something did not go well.
In short, I have found Peer 3’s feedback constructive. I also believe that both compliments and request for improvement Peer 3 cited would be useful for improving my writing skills in the future.
