【摘要】：随着全国各大高等院校在不同课程中的教学改革的不断深入,以及计算机技术的普及和发展,原来的传统的学生考试测评系统已经不再适应现代课堂教学。因此,如何建立合理、高效、规范的试题库,对培养具扎实的基础、知识全面、并具有创新能力的高素质、高内涵人才具有重要现实意义。根据山东华宇工学院《经济数学》课程的传统测评办法及考核改革政策,本课题将通过探讨分析,建立科学实用的高校《经济数学》系列课程的试题库,建立合理、高效、规范的考试命题机制,能帮助学生随机抽取试题,自学自测。主要研究工作有:(1)试题属性的分析。利用数理统计原理对试题进行理论分析,主要是从试题本身的属性以及试卷属性基础上进行研究,主要有难度计算和区分度计算等,以便进行科学的试题筛选与录入等工作。(2)试题库的建立。在对试题属性进行分析之后,确定试题库设计算法、试题库内表关系的分析与建立、试题库表信息的定义等工作,以便于试题库的操作和维护。利用ACCESS设计系统框架及各个模块。系统框架设计从总体上是由五个模块组成的,分别是用户管理模块、课程管理模块、题型管理模块、试题管理模块和自动组合试卷模块。(3)确定各个模块的程序实现、图文混排信息的处理。在进行程序实现时,主要从程序语句的优化性、可移植性和快速性方面进行分析、设计与实现。解决包括图形、公式等图文混排信息的输入、输出。(4)运用改进的遗传算法求解一定约束条件下的多目标参数优化问题,将选题的难度、章节、题型和分值等约束条件转化为目标函数,采用自然数编码方案,较好地实现了自动选题策略。对本研究所提出的《经济数学》试题库进行修改,则可以推广到高校其他课程,具有很好的应用前景和理论研究意义。
[Abstract]:With the deepening of the teaching reform in different courses, the popularization and development of computer technology in colleges and universities throughout the country. The original traditional student examination and evaluation system has no longer adapted to modern classroom teaching. Therefore, how to establish a reasonable, efficient, standardized test questions database, to cultivate a solid foundation, comprehensive knowledge. According to the traditional evaluation method and the examination reform policy of the course "Economic Mathematics" of Shandong Huayu Institute of Technology, this subject will be discussed and analyzed. The establishment of a scientific and practical examination question bank for the series of courses of economic mathematics in colleges and universities, and the establishment of a reasonable, efficient and standardized examination proposition mechanism can help students to select test questions at random. Self-study self-test. The main research work is the analysis of the attributes of the test questions. Using the principle of mathematical statistics to carry out theoretical analysis of the test questions, mainly from the properties of the test questions and test papers on the basis of attributes. There are difficulty calculation and degree of distinction calculation in order to set up the scientific test questions selection and input. After analyzing the attributes of the test questions, the design algorithm of the test questions bank is determined. The analysis and establishment of the table relation in the examination question bank, the definition of the information in the test question bank and so on. In order to facilitate the operation and maintenance of the test questions database. Using ACCESS to design the system framework and each module. The system framework design is composed of five modules, namely, user management module, curriculum management module. Question management module, test paper management module and automatic combination test paper module. 3) determine the program implementation of each module, the processing of picture and text mixed information. In the implementation of the program, mainly from the optimization of the program statements. Analysis, design and implementation of portability and rapidity, including graphics, formulas, etc. Output. 4) using the improved genetic algorithm to solve the multi-objective parameter optimization problem under certain constraints, the difficulty, chapter, item type and score of the topic are transformed into objective function. By adopting the scheme of natural number coding, the strategy of automatic topic selection is well realized, and the modification of "Economic Mathematics" examination question library proposed by this research can be extended to other courses in colleges and universities. It has good application prospect and theoretical research significance.
