You are right, at this point we only allow students to submit one piece of work. The reason is to limit confusion on the reviewers side and to ensure that proper context is kept - it is not always possible to review the conclusion without the introduction. That being said, we are looking at alternative solutions.

In relation to the feedback on feedback, it is again a question of how the teacher implements it. In my own course, the quality of feedback a student provides counts for 30% of their final grade, that makes incentives very clear.

I totally agree with teacher bias being a huge problem. We have a lot of teachers telling us that they are surprised when Peergrade highlights their own personal biases! We are building a way for teachers to also grade people anonymously to further this :).
