基于考情分析的大学计算机基础考评系统设计

Design of University Computer Foundation Evaluation System Based on Examination Situation Analysis

为量化以能力为导向的大学计算机基础课程教学改革中的学生能力提升情况,设计基于考情分析的大学计算机基础考评系统。该系统提供了客观、全面、可信的参考依据,以历年近2000人的大学计算机基础考试成绩样本为研究对象,依据Rasch模型条件及建模方法,设计基于考情分析的相对难度和绝对难度参数指标,应用于选题方式、考评结果分析、能力分析等量化考评过程。该考评系统为大学计算机基础教学考评从考试设置到考评全过程提供一体化支撑,支持多考评模式、多维度考情分析等需求,为教师掌握考生能力提供了一种可量化的工具和方式,亦为教师评估教学效果、改进教学方式提供了参考依据。

In order to quantify the improvement of students′ability in the teaching reform of college computer basic courses,the evaluation system provides an objective,comprehensive and credible reference basis,The system takes the scores,which come from university computer foundation courses examination nearly 2000 pre year,as the research object,in the system.According to Rasch model conditions and model⁃ing methods,the parameter indicators of"relative difficulty"and"absolute difficulty"based on test situation analysis are designed,which can be applied to quantitative evaluation processes such as topic selection method,evaluation result analysis,ability analysis,etc.The evaluation system provides integrated support for the whole process of college computer foundation educational evaluation from examination setup to evalu⁃ation.In order to support the needs of multi-dimensional examination mode and multi-dimensional examination situation analysis,it provides a quantifiable tool and method for teachers to master the ability of candidates,and provides a basis for teachers to improve the educational ef⁃fect and educational methods.
