目的:以CTT和GT作4-6年级MATs的信度检验。方法:重测信度161例,复本信度180例,重测复本信度200例。项目有效样本2002例,其中A本1004例,B本998例。结果:A、B本分量表和总量表重测信度0.91～0.95,复本信度0.87～0.94,重测复本信度0.82～0.89,分半信度0.79～0.90,系数0.90～0.96,评分者信度0.94～0.98,真分数变异0.82和0.86;概化研究表明分测验条目15个左右为宜,分量表与总量表条目量50与100即可。结论:各种信度考验结果基本符合测量学的计量标准。 OBJECTIVE: To test the reliability of MATs in grades 4-6 using CTT and GT. Methods: 161 cases of retest reliability, 180 cases of replica reliability, and 200 cases of retest reliability. The effective sample of 2002 projects, of which 1004 cases of A, B this 998 cases. Results: The test-retest reliability of subscales A and B were 0.91-0.95, the replica reliability was 0.87-0.94, the retest reliability was 0.82-0.89, the fractional reliability was 0.79-0.90, the coefficient was 0.90-0.96 , The reliability of the scorers was 0.94 ~ 0.98, the true score variation was 0.82 and 0.86. The generalized research indicated that there were about 15 subtest items, and the scores of subscales and total scales could be 50 and 100. Conclusion: The results of various reliability tests are basically in line with the metrological measurement standards.
