Marka vs TEAMMATES

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.

TEAMMATES is a web-based peer feedback management system for instructors seeking flexibility beyond their main learning management system. Instructors and students are its intended users, and the project describes the system as highly configurable, including for pedagogical research into peer feedback mechanisms. The service is hosted on Google App Engine and is a joint effort supported by the National University of Singapore School of Computing.
