目的:编制7～9年级语文、数学单科标准化成就测验。方法:在多次试测基础上形成正式测本,采用分层和整群抽样方法,抽取语文样本1008人和数学样本1018人作项目分析,另有一定数量的被试用作信、效度估计及学科专家作内容效度评定。结果:语、数75%的项目难度为0.20～0.80,88%以上的项目鉴别力达到可接受水平,各分测验在各年级和总测验的D值均在0.50以上。语文测验总分的复本信度、分半信度在0.74～0.87之间,数学测验总分的各信度值在0.73～0.88之间。语数A、B题本总分与学科成绩相关为0.47～0.69,探索性因素分析语数各抽取2因素模型为佳,验证性因素分析结果表明两因素模型拟合较佳。结论:7-9年级语、数单科成就测验符合测量学的要求。
Objective: To compile grades 7 to 9 Chinese and maths standardized achievement test. Methods: The formal test was formed on the basis of multiple tests. A total of 1008 Chinese samples and 1018 math samples were selected for project analysis by stratified and cluster sampling methods. A certain number of subjects were used as letters and validity estimates And subject experts to assess the content validity. Results: Language, number of 75% of the project difficulty of 0.20 ~ 0.80, more than 88% of the project discriminatory power reached an acceptable level, the sub-test in all grades and the total test D values were above 0.50. The test scores of the total score of the Chinese test were between 0.74 and 0.87, and the reliability of the total score of the math test ranged between 0.73 and 0.88. Language score A, B, the total score and subject scores related to 0.47 ~ 0.69, exploratory factor analysis of the number of two-factor model is better, the confirmatory factor analysis showed that the two-factor model fitted better. CONCLUSIONS: Grades 7-9 and several single-subject achievement tests meet the requirements of surveying.
