CritViz is web-based software designed to help university instructors implement peer review in online and in-person classrooms, particularly in larger classes where this might otherwise be difficult or impossible. A critique, (or “crit”) well known to art and design classrooms, is a type of peer-review where the focus is on generating formative peer support, rather than on summative peer “grading”. Research has shown that giving peer feedback can benefit learning as much or more than the receiving of feedback (Lundstrom, 2009).[more..]


 CrowdGrader brings peer grading to any classroom: students submit and collaboratively grade their homework. The tool can be used with just a web browser; no complex setup is required!Students learn better:

  • They can see how their peers solved the same problems and learn from it.
  • They get useful feedback.
  • They build motivation by comparing their work with that of the other students.

Instructors benefit:

  • They can easily handle homework grading in large classes.
  • They can read all feedback and discover any difficulties encountered by students.
  • They are in full control of the grades. [more..]


The Expertiza project is software to create reusable learning objects through peer review. It also supports team projects, and the submission of almost any document type, including URLs and wiki pages.The Expertiza platform is a divide-and-conquer approach to producing reusable learning objects through active-learning exercises. Students select from a list of tasks to be performed, with several students selecting each task. They prepare their work and submit it to an electronic peer-review system. The work is reviewed by other students, who offer comments to help the submitters improve their work. The best submissions for each task are selected for use in later courses. These learning objects can be improved iteratively; next year’s class can refine and improve the previous year’s contributions. Expertiza gets students working together to improve others’ learning experiences. It helps them learn; by making them think through the lecture material and apply it to a real-world situation, just as they might do on the job. Because the interactions are asynchronous over the web, distance education students can participate on the same basis as on-campus students. This paper briefly outlines the philosophy behind the system and walks the reader through a demo of the system. [more..]


Mobius SLIP is a web- and cloud-based peer review system designed to administer complex, creative, open-ended assignments in a variety of disciplines and to facilitate elaborate and diverse peer review workflows. The system supports single- and double-looped peer reviewed assignments (as well as no-peer-review assignments), individual-to-individual, team-to-team and team-to-individual interactions, peer and self-assessment, random and manual peer group formation, automatic collection and redistribution of submissions in any media, inline file annotation, and a discussion board. The system scores students as both creators (on the quality of their submissions) and reviewers (on the quality of provided critiques). The system offers efficiency tools for instructors to provide faster, targeted, unique feedback to students and more accurate grading based on multi-faceted performance measures. The system features a variety of the learning analytics and data visualization tools based on the ranking and rating data. Mobius SLIP can be integrated with other LMS via the LTI standard. As of spring 2016, Mobius SLIP has been used by over 100 instructors and 15,000 students on 20 campuses in the US and Canada.[more..]
