There are a variety of online tools available in the market which allow diverse types of self/peer-review and self/peer-assessments.
Self and Peer assessment tools for students’ written work
There is a compulsory calibration part that students need to do (with 3 given samples of written work – high/middle/low quality) before they get to do the real work as assignment to review their peers’ work.
Self and Peer assessment tools for group/team work/contribution
Free open source application. Founded in North Carolina State University, USA. Allows self/peer evaluation on team/group work, but there is a set of ‘behavioural questions (assessment criteria)’ on teamwork which cannot be changed.
Free open source tool. Jointly administrated by Universities of Auckland (NZ), Edinburgh (UK) and British Columbia (Canada). Allows students to create a repository of multiple questions for courses. Students can contribute to creating the repository and build the knowledge base with peers.
