Building A Chemistry Teaching Material Evaluation System In Senior High School Under The Perspective Three Dimensions

The key role of teaching materials in education gives an important mission to the evaluation of teaching materials.To follow the pace of national curriculum reform and carry out the educational purpose of national moral education,this study will build an evaluation model of middle school chemistry teaching material under the three dimensions of philosophy,psychology and pedagogy.To build it,the research mainly draws lessons from the research results of domestic and foreign teaching materials,different subject materials and the important theoretical experience of teaching materials evaluation,integrates the characteristics of chemistry,contacts the development trend of chemistry coursesuses and uses literature review,expert questionnaire consultation,expert arranges method and mathematical statistics and other research methods.The paper mainly includes eight parts: the introduction,the literature review,the research design,the theoretical research,the preliminary construction of the evaluation system of the middle school chemistry teaching material,the revision and perfection of the evaluation index system of the middle school chemistry teaching material,the practice and conclusion.The first part,introduction.The introduction part mainly expounds the necessity of constructing the evaluation index system of middle school chemistry teaching material from policy guidance,teaching material and evaluation of teaching material,and clarifying the theoretical value and application value of research.The second part is the literature review.Through the definition of the core concepts.The author studies the literature and monographs linked with these core concepts,combing the present situation of teaching materials evaluation,finding that the characteristics of the teaching materials are not obvious,the theoretical basis is not systematic.The third part is the research design.Based on the second part,this part clarifies the basic research ideas is recycling from the theory to the practice.And in this part,the research selects various research methods including literature research,questionnaire survey,expert sequencing and consistency test for different research stages.The fourth part is the theoretical research.The construction of the evaluation system of chemistry textbooks in middle schools can not be separated from the support of theory.Many ideas of education are derived from philosophy and developed in psychology.This chapter studies the different ideas under different factions of philosophy,psychology and pedagogy,and puts forward thinking anout the intrinsic value and tool value,material value and spiritual value of teaching materials when establishing the evalution systerm.The fifth part is the initial construction of the middle school chemistry teaching material evaluation system.On the basis of the purpose and principle of the evaluation,this part has obtained the three first-level dimensions: educational,scientific and psychological.According to the characteristics and connotation of each dimension,the corresponding secondary latitude and the third dimension and the corresponding evaluation criteria are set.In the initial construction of evaluation index system,also incorporates the SEC consistency research paradigm and the static quantitative model of quantitative measurement.The sixth part is the construction of middle school chemistry teaching material evaluation model.The first expert consultation to make the whole system is revised,the second expert consultation to determine the weight of the evaluation indicators.In the end,the research uses the Kendall harmony coefficient to ensure the reliability of the study.The seventh part,the middle school chemistry teaching material evaluation index system implementation.In the study,a certain number of expert teachers are selected to evaluate the contents of the "quantity of substance" in the middle school chemistry textbook.Part ?,Conclusion.This part mainly elaborates the research findings from the aspects of the construction of the evaluation index system of teaching materials and the evaluation index of middle school chemistry teaching materials,and finally puts forward the corresponding research suggestions.
