Research On Evaluation Of Evidence Reasoning Ability Of High School Students Based On Rasch Model ——Take The "Organic Compound" Content As An Example

Students' chemical evidence is referred to as the individual psychological characteristics of chemical conclusions in various reasoning methods and through various reasoning processes,based on existing chemical information or data,reflecting the comprehensive quality of students to solve chemical problems.Chemical evidence can directly reflect the level of thinking of students,so it is necessary to understand the level of chemical evidence of students,but the current research on chemical evidence is not enough,especially the "organic compound" evidence reasoning The ability of the capabilities is small,so the study is based on the "organic compound" as an example,which is significant around evidence and its evaluation and its evaluation.The article adopts the literature research method,first analyzes the research background,research significance,research status of chemical evidence,domestic and foreign research status and research,and then combines the "organic compound",in Hannah Sevian and Guo Xipei On the basis of the research of evidence,based on Solo classification theory,the framework of "organic compound" in high school students "organic compound" evidence is initially constructed,and the expertise of the "organic compound" constructed "organic compound" evidence is performed.The amendment finally established a framework for the level of "organic compound" evidence.Based on the framework of high school "organic compound" evidence,the development of assessment tools was completed under the guidance of Wilson's "four-cornerstone" measurement model,and corrected and optimized the evaluation tool through the predetermined testing tool.Evaluation tools for measured research.Finally,the assessment tool was used to measure two key classes and two ordinary classes in the third grade of Fuyang City,Anhui Province.The results of the research were as follows:Through the study,most of the "organic compound" evidence in the high third grade of the school is mostly concentrated in three levels of three and horizontal,which reaches a high level,but the school requires "organic compound" to meet the level of four,students Level is obviously a certain distance from the school's requirements.From the descriptive statistics of the "Organic Compound" evidence and the results of the independent sample T test,the "organic compound" evidence of the "organic compound" evidence in gender is significant difference in gender(probably " Related content contains some memory-related things),there is also a significant difference in the class type,and there is no significant difference in the ordinary classes of different types of teaching teachers.
