Study On The Consistency Of Chemistry Textbook Exercises And Curriculum Standards Based On Core Literacy

The promulgation of the 2017 edition of the new curriculum standards marks that my country's basic education curriculum reform has entered a new stage,and the teaching of chemistry is also undergoing tremendous changes in the reform process.The new curriculum standard requires that basic education courses be able to implement the task of cultivating people,improve the core competence of students,and also provide an important basis for periodic evaluation.The new textbooks are compiled according to the curriculum standards,and after-school exercises are an important part of it,which bears the important function of diagnosing and developing students' academic literacy levels.The consistency of the textbook exercises and the curriculum standards is worth exploring.This thesis takes the curriculum standards and the new textbooks after-school exercises of the Luke version and the People's Education version as the research objects.The core research procedures are as follows.First,the determination of the consistency evaluation model.Through the literature research method,determine the selection of the Weber consistency evaluation model to evaluate the consistency of the textbook exercises and the curriculum standards,and combine the level of core literacy to improve the Weber model,and determine the target depth level evaluation standard based on the core literacy;Second,code the curriculum standards and textbook exercises based on core literacy.First,through text analysis,the five core literacy are extracted into specific dimensions,and then the levels are divided according to the dimensions;combined with the content requirements of the curriculum standards and the academic level requirements,the topic 3 material structure foundation and chemical reaction law content field The standard encodes three aspects of literacy category,dimension andlevel;the exercises in the relevant chapters corresponding to topic 3 in the new textbooks of Luke and People's Education Edition are respectively encoded in three aspects.Third,data statistics and analysis.Mainly analyze two aspects of content,the first one is to analyze whether the two editions of the textbooks are consistent with the curriculum standards in the four dimensions of knowledge category,knowledge depth,knowledge range and distribution balance in the two editions according to the Weber model;the second is to compare the core literacy of analytical chemistry in the two editions Contrast performance in textbook exercises.After research and analysis,the following conclusions are drawn,1.The Luke version has high consistency in the dimensions of knowledge depth and knowledge range,but there are 3 modules in the knowledge category and distribution balance that are unacceptable or barely acceptable;the People's Education version has a high level of knowledge category and knowledge range The consistency of the two modules in the depth of knowledge and distribution balance has unacceptable levels.Comprehensive analysis shows that the consistency between the exercises and the curriculum standards of the PEP version is higher than that of the Luke version.2.In terms of the distribution of chemistry core literacy types,in the Luke version,literacy 1> literacy 3> literacy 2> literacy 4> literacy 5.The Luke version pays more attention to macro identification and micro analysis and evidence reasoning and model recognition.In the People's Education version,literacy 1> literacy 2> literacy3> literacy 5> literacy 4,the People's Education version pays more attention to macro identification and micro analysis and change concept and balance thought,but less scientific inquiry and innovation consciousness.3.In terms of the distribution of the core literacy level of chemistry,the Luke version and the PEP version have the same distribution trend,both are Level 1> Level2> Level 3> Level 4,and more than 90% of the exercises in the two editions are concentrated in level 1 And level 2,the amount of exercises in the PEP version is higher than that in the Luke version.The overall analysis shows that the PEP version is higher than the Luke version in the level of exercise depth.Based on the consistency evaluation model of core literacy improvement textbook exercises and curriculum standards,this research proposes a new exercise evaluation model to diagnose and diagnose exercises from six aspects,knowledge category,depth,scope,distribution balance,and core literacy type and level distribution.Evaluation.This model is applicable to the study of consistency between textbook exercises or academic evaluation test questions and curriculum standards under other themes.From a qualitative and quantitative perspective,it provides a reference for the design,revision and evaluation of textbook exercises or academic level test questions.
