Marka vs Mobius SLIP

Marka is peer evaluation software for teachers collecting rubric-based feedback on classroom group work and producing consolidated reports. Teachers can create reusable analytic or holistic rubrics with their own scoring scales and criterion indicators. Students see aggregate results and unattributed public notes, not individual peer scores. Results and notes stay hidden until at least three evaluators submit, unless a teacher overrides the threshold for a student. A teacher-only Peer Integrity Engine flags patterns such as free-riding, mismatched self-ratings, rushed scoring, cliques, and rater bias; it does not change scores automatically. Reports can include dashboards, CSV exports, cross-period comparisons, printable reports, and gradebook-ready exports. Teachers import rosters from CSV, and students enter with teacher-issued seven-character codes without creating accounts or providing email addresses. Marka works without an LMS connection and is available on the web and through a lightweight Android app. Its free Basic plan supports up to 3 classes and 50 students per class, with full report preview only.

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.
