Mobius SLIP vs PeerEval

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.

PeerEval is a peer assessment tool for classroom evaluation sessions. Instructors use a browser interface to enroll students, build evaluation rubrics and download results for analysis. Rubric scoring and moderation tools are supported, along with learning management system integration and gradebook synchronization. Students enter an instructor-provided session name to access an evaluation, add written comments and modify submitted work while the class session remains active. The service runs on the web, and an iPhone app is listed as free on the Canadian App Store. PeerEval is described as paid, but pricing is available only on request and the maker’s pages do not state plan amounts. The App Store identifies Thomas N Robb as the developer and seller. Apple’s listing says the developer has not provided privacy-practice details to Apple. Instructors therefore get browser-based setup and result handling, while students complete and revise rubric-based peer evaluations during class activities.
