There is an increasing pressure on universities to establish procedures for the recognition and certification of student participation in MOOCs. In order to guarantee that the evaluation procedures are in line with the quality of the procedures traditionally established in the university, a proposal for an enhanced peer assessment is required to allow a more precise review of the students' tasks and the assessments provided by his colleagues, considering procedures of verification of originality and a complete rubric for the peer review that takes into account reviewer’s history for a correct grade calibration. This paper describes the implementation of the evaluation tool, and an experimental validation that indicates that the majority of the students who have used the tool for the revision of assignments have generated grades closer to the revisions generated by the professors in the study.20182018/01International Journal of Emerging Technologies in Learning (iJET)131206–21910.3991/ijet.v13i01.7461http://online-journals.org/index.php/i-jet/article/view/74611863-0383semi-automatic evaluationself-plagiarismpeer assessmentP2P activityoriginality checkMOOCLearning Tools Interoperabilityhttp://online-journals.org/index.php/i-jet/article/view/74617461-25655-1-PB.pdf
