摘要
运用Rasch模型探查高二学生对"化学键"概念的认知情况,运用Conquest软件和Winsteps软件对测试结果进行分析。结果表明:基于Rasch模型编制的测试卷能客观有效地检测学生对"化学键"概念的理解,为一线教师的有效教学提供学情基础。
This paper used Rasch model to measure senior two students' understanding of "chemical bonds" concept, used Conquest and Winsteps software to analyze the test results. The results showed that the test based on Rasch model could effectively assess students' understanding of "chemical bonds" concept, providing learning status for the effective teaching of front-line teachers.
