Co-rank: An Online Tool for Collectively Deciding Efficient Rankings Among Peers

摘要

Our aim with co-rank is to facilitate the grading of exams or assignments in massive open online courses (MOOCs). MOOCs have emerged as a new education trend; they are online platforms that offer, to a huge number of students from all around the world, open access to top-class courses and related educational material. As the number of students attending a single online course usually exceeds 50,000, the issue of effective grading and assessment of students has been recognized as an important bottleneck for the success of such platforms. Since professional graders are costly, inexpensive grading is absolutely necessary in order to make the new educational experience beneficial for the students and, at the same time, viable for the MOOC platforms.
