摘要
用多元概化理论 (MGT)研究了国家语委编制的普通话测验。在G研究中 ,利用香港人普通话测试的数据 ,估计了引起分数变异的各种来源的方差与协方差分量。在D研究中 ,首先估计了该测验 3个部分的全域分数和各自的概化系数等技术指标 ,然后估计了全域合成分数及其概化系数、信噪比等指标。结果表明 ,该测验的信度从总体上讲是较高的 ,把三个部分的全域分数进行合成也是合理的 ,但从细节上看其第 3部分的信度较低。另外 ,当评分者个数为 3、试题数量为 2 8时 ,测验的第 1、2部分的信度已经较高 ,因此 。
In this study, we used Multivariate Generalizability Theory (MGT) to analyze the Putonghua Test conducted by the State Language Commission Random effect variance and covariance components were estimated in the G study Generalizability coefficients for each part of the test and composite generalizability coefficient for the whole test were estimated in the subsequent D study The results showed that the generalizability coefficient (reliability) is acceptable for the whole test but not for Part 3 (language use) of the test It is reasonable to combine the three part universe scores into a composite universe score in this test Since the generalizability coefficients of Part 1 and 2 in the test are large when employing three raters and 28 items for each part, therefore future test design can use fewer items
