摘　　要：信息熵是信息系统中的一个重要核心概念。通过计算和比较高二化学试卷中的选择题与部分填空题的信息熵,文章分析了信息熵在评估试卷难度及揭示学生问题中的意义,提出了一个量化指标用于评价高二化学试卷的质量,可以从侧面评估化学试卷的优劣。此方法完善了对学生真实水平的分析,并能够通过信息熵的计算来描述学生的学习状态。Information entropy is an important core concept in information systems.The article analyzes the significance of information entropy in evaluating the difficulty of high school chemistry test papers and revealing student problems by calculating and comparing the information entropy of multiple-choice questions and partial fill in the blank questions.The article proposes a quantitative indicator for evaluating the quality of high school chemistry test papers,which can be used to indirectly evaluate the quality of chemistry test papers.This method improves the analysis of students'true level and can describe their learning status through the calculation of information entropy.
