摘要：

目的：尝试在项目反应理论的指导下，编制三年级数学成就测验，为学科学习的评价提供一辅助工具。方法：用贝佳方法检验试测数据单维性，利用ANOTE软件估计项目参数，采用铆测验设计进行参数等值。结果：四套试卷均符合单维性要求，基本拟合三参数逻辑斯蒂克模型，项目拟合度都在90%左右，最终选取52个项目组成正式测验。结论：正式测验的信息量达到31.1548，估计标准误为0.1267，符合项目反应理论的要求。

Objective: Under the guidance of the item response theory, the author designed the mathematics achievement test and provided a subsidiary test for the evaluation of the performance of mathematics of grade 3.Methods: A two-way specification table was designed before the experiment, The Bejar method was carried out on the data collected, the parameter was evaluated by ANOTE software, the research adopted Anchor-test design, and finished the item parameter equating.Results: All the results were in accordance with the request of unidimensionality, the data fitted Three-Parameter Logistic Model, and finally 52 items were selected to constitute the formal test.Conclusion: The formal test information reaches 31.1548, SE=0.1267, which is accorded with the requirements of the item response theory.
