Analysis and Evaluation of Examination of Principles of Chemical Engineering Papers

通过化学工程基础考试试卷分析,评估无机非金属材料工程专业学生对该门课程知识点的掌握程度和教师授课质量。采用校级自主开发的试卷分析系统进行2015级和2016级化学工程基础试卷难易度和区分度的分析,并给出成绩分布图。考试成绩近似正态分布,平均成绩68.5和64.3,整套试卷难度为0.31和0.44,区分度为0∶24和0.37。分析结果表明,试卷题型和区分度尚可,但难度偏低。教师应采用多媒体教学手段激发学生的学习兴趣,强化学习引导,提高试卷质量等措施提高教学效果。

To improve the professional teaching of inorganic nonmetallic materials,examination on the final exam paper analysis of engineering principles of chemical engineering can appraise the knowledge degree and teaching quality.The software of examination analysis system is used to calculate the difficulty and discrimination,and create grade distribution curve of the final exam paper of the class of 2015 and 2016.Analysis Results showed that the scores was approximately a normal distribution,the average score was 68.5 and 64.3.The difficulties of the papers were 0.31 and 0.44,and the discrimination of the papers was 0.24 and 0.37.The results suggest that question types is various and degree of differentiation is reasonable,but difficulty is relatively low.Leading teacher should use multimedia teaching means to increase their interest,strengthen teaching guide and improve test paper quality for improving the teaching effect.
