IMPROVE SELF-REVIEW
Introduction
Expertiza is an online system that is used by students to view/submit assignments and review others' work. Expertiza also provides tools to visualize the scores and gauge the improvements made during the course semester. It also facilitates and monitors team projects. It is targeted at educational and non-profit organizations. The project is funded by the National Software Foundation (NSF), NCSU Learning in a Technology-Rich Environment (LITRE) program, the NCSU Faculty Center for Teaching and Learning, the NCSU STEM Initiative, and the Center for Advanced Computing and Communication.
Expertiza is an open-source project with the source code available as a public repository on GitHub. It is developed using Ruby on Rails and is increasingly becoming robust thanks to the innumerable bugs being fixed by the community.

Task Description
Display self-review scores juxtaposed with peer-review scores in the regular “View Scores” page and the alternate (heat-map) view. Combine self-review and peer-review scores to derive a composite score, based on closeness to the peer-review. Author(s) should be required to submit their self-evaluation(s) before seeing the results of their peer evaluations. Design an appropriate way to aggregate self-reviews by different members of the project team.
Approach
Student has the task of performing review of others' work as well as self review. Every team gets their review from peers and at present the composite score is the average of all the review scores that they have received. Added to this score, the self review score is also calculated for each team member, based on its closeness to the peer reviewed score. To implement this, the student needs to review his own work based on the same rubrics used for peer review and only after completion of the self review, their peer review scores will be visible. The composite score is calculated by the sum of the peer review average score and 100 minus the difference between self and peer review score. The self review score is displayed adjacent to the peer review score. As the composite score is based on the individual self reviews, they vary for each member of the team unlike the peer review score which is the same.
