Expertiza vs Mobius SLIP

Expertiza is a free, open-source web application for instructors to deploy assignments and students to submit and peer-review learning objects. Submissions can include articles, code, websites, URLs, and wiki pages; students can also form teams and sign up for topics. The system supports rubric scoring, moderation, one-way reviewer anonymity, and manual review allocation. The project says it is used in select NC State courses and by professors at several other colleges and universities. It can be run locally or deployed to production, with development setup guides for Ubuntu/Debian, macOS, and Linux RHEL. Developers need a JVM. A documented Moodle LTI integration allows assignments to launch from Moodle and sends grades to its gradebook, but setup requires a Moodle administrator to register and activate Expertiza as an external tool provider. The project also describes a generic synchronization interface intended for LMS platforms such as Blackboard or Canvas. The repository lists an MIT license and points to instructor and student manuals, presentations, and videos.

Mobius SLIP is a web-based social learning system for creating, reviewing, and critiquing assignments. Each assignment moves through Submission, Review, and Reaction: students submit work, assess peers' work, then respond to the reviews they receive. Students take both author and reviewer roles, and the process is anonymous unless the instructor directs otherwise. Analytics cover attainment, bias, controversy, and self-assessment accuracy for both roles. Suggested peer grades depend on review reliability, and instructors can override them. Instructors can monitor activity in real time, review work, provide feedback, and use course and assignment analytics to guide students. There is no stated cap on courses. Each student may upload one file of up to 10MB; videos must be hosted elsewhere and submitted as links. Students register with an instructor-provided code and a college or university email address. Instructors can upload a roster or allow self-enrollment, and students confirm registration by paying a registration fee. The product is paid, with pricing available on request, and instructor demos can be requested.
