Online Assessment System for Individual Scores

The Online Assessment System for Individual Scores (OASIS) is a new process that aims to broaden students’ learning experiences with team projects and offer a transparent scoring rule for teachers to fairly assess individual student contributions to a team project in courses of any discipline at higher education institutions.

It is an innovative solution to the major problems in team-based learning faced by teachers worldwide. It guards against strategic behaviours of gaming and collusion by discouraging free riding upfront at project commencement and penalizing free riders at project completion.

It offers an easy-to-implement and time-efficient means to generate scores that reflect individual contributions in team projects. Using peer assessment data mutually agreed by a project’s team members, these scores obey the academic assessment principle of due diligence, fairness and transparency and can withstand third-party independent review and verification.

With the optional use of student surveys, it collects empirical data for evidence-based teaching and learning.


In response to student complaints of free riding, Prof Chi-keung Woo of Education University of Hong Kong (EdUHK) launched a beta version of OASIS in August 2017. Since then, the OASIS team has been actively recruiting users at higher education institutions worldwide. It plans to continue improving the system, thanks to the success of early adopters in Hong Kong, India and Texas and a teaching development grant from Hong Kong's University Grants Committee(UGC).
