中美学生数学学习水平的定量比较

Quantitative assessment of math learning for Chinese and American students

给出了将不等值的原始分数转换为等值的能够进行比较和运算的标准分数的计算方法,并依据变换参数给出学习水平定量标准化评价,建立学习水平相对差距的标准化比较评价模型,据此做了中美大学生数学学习水平的实证抽样标准化评价比较.利用Kappa一致性检验和理想模型,分析了将原始分数转换为标准分数计算方法的可靠性和有效性.

Proposed a computing method for converting nonequivalent original points to equivalent standardized points which can be used for assessing and comparing.Quantitative standardized assessments was given based on converting parameters.A practical standardized assessment model was proposed for comparing students’learning.Experiment of sampling standardized comparing Chinese and American students＇ mathematical learning was done.At last Kappa consistency test and ideal model test were taken to evaluate reliability and effectiveness of the computing method.
