毕业论文设计IRT理论会计考试系统中设计与实现.docVIP

本科毕业论文（设计） 摘要 近年来，项目反应理论（IRT）已经成为教育考试领域的研究热点。随着计算机硬件的发展和计算机的普及，项目反应理论正在快速的被应用于会计在线考试系统中。现存的会计在线考试系统中出现的考试设计没有科学性、不能做到“因人而测”的问题和不能客观准确的评估会计考生的知识和水平的问题。因此，将IRT应用于会计在线考试系统中对于实现客观准确的评估会计考生的能力，具有十分重要的意义。 本文从现有会计在线考试系统的现状和会计在线考试系统存在的问题入手，介绍了IRT的理论和IRT的反应模型；通过分析项目反应理论会计在线考试系统考试中的应用，建立了数学模型，运用已知的题目区分度(a)、题目难度（b）、题目的猜测系数（c），求解出会计考生答题后重新估算的能力值（），再根据得出的,选择与会计考生能力值相适应的的题目。在考试过程中，当考生的能力逐渐收敛到一点之后，会计系统结束考试。最终，会计在线考试系统得到一个考生的能力值。从而达到客观、准确的评估考生的会计知识和会计能力的目的。 关键词：项目反应理论； 逻辑斯蒂模型；项目信息函数 Abstract Advances in computer technology and network technology.has spawned a large In recent years, item response theory (IRT) has become a hot topic in the field of Education Examination . With the popularity of computers and computer hardware development , the project is being fast response theory is applied to accounting online examination system. Existing accounting online examination system design does not appear in the exam science, can not do the level of knowledge and measured from person to person problem and objective , accurate assessment of the accounting candidates . Therefore, the IRT online examination system used in accounting for the realization of the objective and accurate assessment of the candidates ability in accounting , has very important significance . From the examination system and the status of existing accounting online examination system problems , this paper introduces the theory and reaction model of IRT IRT ; reaction theory accounting exam online examination system by analyzing the project application , a mathematical model has been through known topics discrimination (a), item difficulty (b), the subject of speculation coefficient (c), the ability to solve the candidates to answer back after the accounting value estimate , according to the results , the ability to select the candidate with the accounting value of the phase adaptation problems. During the exam , the candidates ability to gradually converge when the point after the end of the examination of acc
