摘要
针对不同主体评价不同客体存在评价的不公平性,提出一种改进评价算法。首先,建立不同主体、不同客体的教学评价模型的数学模型,并将各个评价主体给出的评价分数按照高低进行排序,线性变换到同一数值空间;然后根据各类评价主体的评价结果关联程度计算各类评价主体的权系数和加权平均计算各个客体的得分。通过仿真计算,验证了本改进算法有效。
In terms of the unfairness of diverse objects being evaluated by diverse subjects, an improved assessment algorithm was proposed. Firstly, the mathematical model of teaching evaluation model about diverse objects being evaluated by diverse subjects was set up, and the assessment mark ranked from high to low and were mapped into the same score range with linear transformation method. Secondly, weight coefficient of diverse subjects was calculated by relevant degree of the assessment results given by diverse subjects and the marks of diverse objects were calculated. Finally, an example was given to illustrate the effectiveness.
