I would resequence to get the 2 sentences that deal with peer, and the 2 that deal with self, together.

Peer assessments allow instructors to assign questions that may not have definite answers, with students grading each others' responses. Students learn by comparing their peers' answers to a rubric that you create. Peer assessment problems can also include self assessments. In self assessments, students compare their own responses to the rubric.
