主 题:Smart education peer assessment collaborative learning
摘 要:This paper introduces a novel mechanism to improve the performance of peer assessment for collaborative ***,a small set of assignments which have being pre-scored by the teacher impartially,are introduced as“sentinels.The reliability of a reviewer can be estimated by the deviation between the sentinels’scores judged by the reviewers and the impartial *** filtering the inferior reviewers by the reliability,each score can then be subjected into mean value correction and standard deviation correction processes *** the optimized mutual score which mitigated the influence of the subjective differences of the reviewers are *** perform our experiments on 200 *** are asked to submit their assignments and review each *** the experiments,the sentinel-based mechanism is compared with several other baseline *** proves that the proposed mechanism can effectively improve the accuracy of peer assessment,and promote the development of collaborative learning.
