摘要
在网络课程的学习评价中,主观性命题多采用同伴互评的方法.由于评价者的差异,同伴互评结果的准确性往往受到质疑.为此,采用肯德尔和谐系数W对评定结果进行一致性检验,并设计了相关算法.该算法在《现代教育技术》网络课程中的应用表明,一致性检验可以为教师适当介入同伴互评提供依据,从而提升同伴互评的准确性.
In the learning evaluation of online course,the subjective proposition is the method of peer assessment.Due to the difference of the evaluation,the accuracy of peer assessment results is questioned.To this end,the Kendall harmonious coefficient W is used to test the consistency of the evaluation results,and the related algorithms are designed.The application of the algorithm in the online course of＂modern education technology＂shows that the consistency check can provide the basis for teachers to intervene in peer assessment,so as to improve the accuracy of peer assessment.
