基于Rasch模型的高中生物试题解析

Analysis of High School Biology Test Items Based on the Rasch Model

摘要: Rasch模型作为一种现代教育测量工具，以其精准的反馈在试题分析和学生能力评估中发挥重要作用。本研究以高中生物测验为例，从单维性检验、试卷拟合度、题目拟合度、怀特图和气泡图等方面展开分析，采取数据与试题内容相结合的方式对试题进行解析，依据数据与试题解析结果，提出试题分析需将所得数据与试题内容相结合、合理设置题目难度系数，提高试卷结构的科学性和区分度、创新试题形式，加强生活化情境设计等建议。

Abstract: Rasch model, as a modern educational measurement tool, plays an important role in test analysis and student ability assessment with its accurate feedback. Taking high school biology test as an example, this study analyses the test questions in terms of unidimensionality test, test paper fit, items fit, Wright map and bubble chart, and analyses the test items by combining the data with the contents of the test items. Based on the results of the data and the analysis of the items, it is proposed that test items should be analysed by combining the data with the contents of the test questions, reasonably setting the question difficulty coefficients, and improving the scientificity and differentiation of the structure of the test paper; innovative forms of test items and strengthening the design of life situations.
