Based On The Development And Research Of Chemistry Core Literacy Test Questions

With the development of a new round of chemistry curriculum reform,chemical core quality has become a hot research issue.Many scholars in China have begun to study the issue of chemical core quality in recent years and have gained valuable experience.However,research data focusing on the examination of chemical core qualities of high school students is rare.The study of chemical core literacy tests is not only the key to the breakthrough in theoretical research of chemical core literacy,but also is the bottleneck that restricts the reform of chemistry curriculum in middle schools.The study of chemical core literacy survey has become an important research topic.By reviewing the relevant literature on chemical core qualities,we can combine the five content dimensions and academic quality of the chemical core quality and determine the four content levels and four grade levels of the core chemical literacy.The four content dimensions include: Dimension 1,"Macro Identification and Micro Analysis" and "Evidential Reasoning and Model Cognition";Dimension 2,"Change Concept and Balance Thinking";Dimension 3,"The Spirit of Scientific Inquiry and Innovation";Dimension 4,"Scientific Spirit and Social Responsibility." The determination of the four levels is consistent with the standard of academic quality testing of the chemistry curriculum.Then,on the basis of analyzing the knowledge content of chemistry textbooks,we should formulate examination questions for chemical core qualities.And select a small sample,conduct a pre-study,and revise the chemical core literacy test questions.Selecting 1124 students from three senior high schools in Jining City as the research object,conduct the actual measurement,collect and process the test data,and use the SPSS 18.0 statistical software package for data management and analysis to form a formal survey questionnaire for chemical core qualities and determine the difficulty of the test distinction.Data analysis was performed with winsteps2.0 statistical software.The correspondence between the test subject's ability and the test difficulty was analyzed to determine the validity of the level design of test questions.The research shows that:(1)The questionnaire structure is clear,each test has good difficulty and differentiation,the questionnaire has good reliability and credibility;(2)The ability of the test and the difficulty of the test show a good corresponding relationship,and the level of the test questions have a scientific and effective design.The innovation of this research is mainly reflected in: it was based on the contentand grade level of chemical core literacy and combined with the knowledge of high school chemistry.And the compilation of chemical core literacy survey questionnaire is innovative,and provide a reference for chemical core literacy testing tool.
