【摘要】：等值研究是心理与教育测量理论和实践研究中的重要领域。在保证考试公平、进行教育质量评估、题库建设和计算机自适应化研究中,都具有非常重要的实践和理论价值。测验理论从经典测试理论(CTT)到项目反应理论(IRT)的发展,IRT等值克服CTT等值的各项局限,实现将被试能力与特定项目反应概率之间的关系模型化。然而,IRT测验单维性假设与心理、教育测验的实际常常不符。现实情境中通常假设测验单维,但是实际是包含或者隐含着多个特质维度。多维项目反应理论(MIRT)是近二十年来测验理论的新进展之一,也是主要的发展领域之一。由于理论研究与实际需要,经常需要对不同的测试、考试、进行等值比较。尽管测试的编制者努力使不同版本的测试,在难度上保持一致。但是实际上难度、区分度的偏差难以克服,难以保证对被试的公平性。当前很多等值研究都集中在等值方法的研究,以及将单维等值方法拓展到多维领域,用单维以及多维的不同结构模型进行的等值研究相对比较少。国内外虽然也有相关研究,但涉及的面仍不够广,数量相对较少,对于多维简单结构与复杂结构的等值研究甚少。本文尝试对单维测验进行等值转换,并且将单维等值与项目间多维结构等值进行比较。首先利用R软件、进行数据模拟,然后主要分为二个研究设计:研究一、单维项目反应理论等值。研究二、多维项目反应理论等值。最后将单维等值与多维等值操作结果进行比较。单维模型、多维模型不同等值方法的结果进行比较,提高测试的有效性和灵活性,以期促进等值的实践应用。
[Abstract]:The study of equivalence is an important field in the theoretical and practical research of psychological and educational measurement. It is used to ensure the fairness of the examination, to evaluate the quality of education, to construct the question bank and to study the adaptation of computer. The development of test theory from classical test theory to item response theory overcomes the limitations of CTT equivalence. The relationship between the ability of the subjects and the response probability of a particular item is modeled. However, the one-dimensional hypothesis of the IRT test is often inconsistent with the psychology and the reality of the educational test. In reality, it is usually assumed that the test is one-dimensional. But the multi-dimensional item response theory is one of the new developments of the test theory in the past two decades. It is also one of the major areas of development. Due to theoretical research and practical needs, it is often necessary to compare different tests, tests, and equivalents, despite the efforts of test compilers to make different versions of tests. In fact, the deviation of degree of distinction is difficult to overcome, and it is difficult to ensure the fairness of the subjects. At present, many studies on equivalence are focused on the study of equivalence methods. And the one-dimensional equivalence method is extended to the multi-dimensional domain, and the equivalent studies with the single-dimensional and multi-dimensional structural models are relatively few. Although there are some related studies at home and abroad, the scope involved is still not wide enough. The number is relatively small, and there is little research on the equivalence of multidimensional simple structure and complex structure. And the one-dimensional equivalence is compared with the multi-dimensional structural equivalence between projects. Firstly, the data is simulated by R software, and then it is divided into two research designs: research one, one-dimensional item response theory equivalence and research two. Finally, the one-dimensional equivalent and multi-dimensional equivalent operation results are compared. The results of different equivalence methods of single-dimensional model and multi-dimensional model are compared to improve the effectiveness and flexibility of the test. In order to promote the practical application of equivalence.
