Research On The Consistency Between Exercises And Curriculum Standards In High School Chemistry Textbook

Textbook exercises are not only an important part of textbooks,but also an important tool for daily academic evaluation.Therefore,it is necessary to carry out research on the consistency between textbook exercises and curriculum standards.The study process is as follows.Firstly,sort out and summarize the relevant research on curriculum consistency and textbook exercises at home and abroad.Then the textbooks "Chemistry Selective Compulsory 3: Fundamentals of Organic Chemistry" and "General High School Chemistry Curriculum Standards(2017 Edition,2020 Revision)" are selected as the research objects.Then use the SEC model as the research tool and use content analysis method and statistical analysis method to conduct the consistency research between textbook exercises and curriculum standards.Secondly,based on the research needs,a localized SEC analysis framework is constructed,the academic requirements in the curriculum standards and textbook exercises are encoded respectively,and the reliability and validity of the coded data are tested.Then calculate the consistency coefficient between curriculum standards and textbook exercises,use various forms such as surface charts,heat maps,and radar charts to characterize the data,and analyze the research data.Finally,based on the coded data,research conclusions are drawn,and suggestions for the compilation and utilization of textbook exercises are proposed.The study find that the textbook exercises and the curriculum standards are statistically consistent.In terms of content topics,"Properties and Applications of Hydrocarbons and Their Derivatives" has a good consistency,but the consistency in "Composition and Structure of Organic Compounds" and "Biological Macromolecules and Synthetic Polymers" needs to be improved;In terms of cognitive level,the weight of textbook exercises in cognitive level 1 and 2 is higher than that of the curriculum standard,and the higher parts are concentrated in "Changing Ideas and Balanced Thinking","Evidence Reasoning and Model Cognition" and "Scientific Inquiry and Innovation Consciousness".In addition,the weight of the three core competencies of chemistry and innovation consciousness at cognitive level 3 and 4 is lower than the curriculum standard.Therefore,in the process of compiling textbook exercises,the proportion of investigation on various content topics and core chemistry literacy and its level should be adjusted.Teachers should face up to the value of textbook exercises,make appropriate adaptations to exercises in the process of utilization,and use similar exercises flexibly.
