Establishment Of Evaluation Index System Of Core Literacy For The Subject Of Chemistry

Based on the high school chemistry curriculum standards(2017 Edition)and literature analysis,the evaluation index system for discipline core literacy of common inorganic substances and their applications is established in this paper.According to the established evaluation index system,the questionnaire is compiled.Finally,the validity of the evaluation index system is tested by questionnaire investigation.In this paper,the background and significance of the topic selection are first clarified,and the related literature analysis of the core literacy and the chemistry disciplinary core literacy is carried out.At present,it is found that both at home and abroad,the research on core literacy has been carried out,and there have been some achievements in this field abroad.However,the domestic research on core literacy is still in its infancy,and the research on the evaluation of core literacy is still at the theoretical level.Although the curriculum standards of various disciplines have been issued,and the academic quality has been divided into academic quality levels,teaching and evaluation recommendations have been given,but only macro-guidance for the evaluation of the discipline core literacy has been given.It is also necessary to refine the evaluation of the discipline core literacy.And this article is about the evaluation index system for discipline core literacy of common inorganic substances and their applications research,therefore,this article topic has the frontier and the practical significance.Secondly,through combing the content of common inorganic substances and their applications,combining with the literature research and the development of discipline core literacy,this paper establishes the evaluation index system of discipline core literacy of common inorganic substances and their applications.The evaluation index system is divided into two parts.The first part is the description of the correct value and the necessary character of the subject,and the second part is the description of the discipline competence performance of the subject.Common inorganic substances and their applications discipline competence indicators are divided according to the students' cognitive activities of chemical discipline and chemical problem solving activities in the school.Among them,the primary indicators are classified into classification and representation ability,logical thinking ability,and applied practice ability.Under each first-level index,three second-level indexes are separately divided,and each second-level index is described in detail.And the corresponding common inorganic substances and their applications of the development of discipline core literacy are divided,and the level of them is also divided.Finally,this paper tests the established evaluation index system through the form of questionnaire survey,and tests the validity of the questionnaire by statistical analysis of the data by using the social science statistics program SPSS.The validity of the established evaluation index system by independent-sample t test,One-Way ANOVA and so on.Through the data analysis,it is found that the questionnaire and the evaluation index system are effective.In addition,the scores of students in all dimensions of the core literacy development of the subject were counted.It also counts the score rate in the correct value concept and necessary character,as well as in the performance index of subject ability.Based on the analysis of statistical data,this paper summarizes the problems existing in the development of students' core literacy of chemistry subject,and puts forward some suggestions for solving them.And the established evaluation index system by the analysis is provided with the diagnosis function and the guidance function.It can be used for guiding the teaching of the teacher and the study of the students.It can be used for comprehensively evaluating the common inorganic substances and their applications discipline core literacy of the students,and the concept of the integration of teaching,learning and assessment has been put into practice.This also shows that the evaluation index system can also be used for reference in the establishment of the evaluation index of core literacy of other subjects or disciplines.
