OCS Assignments System

Students are extending the OCS assignment lifecycle from creation through submission, analytics, and grading. The system supports inserting rubrics directly into assignments, providing immediate AI evaluation, and assigning student-generated lessons for peer review and grading. After initial automated evaluation, live review sessions follow, allowing students and graders to discuss challenges, successes, and the work. A grader assignment view supports this process by giving graders a place to review submissions, record observations, and provide an overall assessment. The work integrates OCS interfaces with the Java/Spring backend, AWS S3, and AWS RDS/SQL, moving assignment data, student activity, scores, and feedback into a shared system rather than separate tools and spreadsheets.
