A NEW METHOD FOR PEER ASSESSMENT IN MOOCS

Summary/Abstract: The Massive Open Online Courses (MOOC) is the most recent development in open online distance learning. The fundamental characteristics of MOOCs are: Massive, the courses are designed to support a huge number of participants; Open, the courses are not required to pay a fee to participate; Online, the learners can access to courses via the Internet, and Courses, to say that these are courses with pedagogical objectives. Thus, the most challenging is designing an accurate method to evaluate and provide feedbacks, especially for open questions (especially Problem Situation), since the high number of learners. To tackle this problem, MOOCs use peer assessment techniques (known as peer grading) that suffer from a lack of credibility. In this paper, we present a new method for peer assessment in the Massive Open Online Courses, in order to improve the accuracy of grading results. Our proposition is divided into three (3) steps: clustering unit, assessment and treatment of the results. The clustering unit is the task of grouping learners with similar profiles. Clustering unit aims to group learners based on the parameters stored on learners’ modeling within the MOOCs. After the clustering unit, the learners are required to grade a small number of their peers’ tasks as part of their own task.. Afterwards, the scores are dispatched for treatments where a synthesis is given for assessment. To assess the feasibility of the proposed peer assessment, we report here the results of the tests conducted on the developed prototype.
