Research On The Evaluation Index System Of Elementary School Science Textbooks

As one of the main sources of teaching content,textbook plays a carrier role in the teaching process.The quality of textbooks directly affects the achievement of teaching objectives.Due to the constant reform of primary school science curriculum and the gradual diversification of textbooks,how to choose the right textbooks is an important problem to be solved urgently.The selection of primary school science textbooks directly affects teachers' teaching methods and students' learning outcomes,and restricts the reform of basic education and the process of science education.China's education authorities have issued a number of relevant documents and policies,including the compulsory education primary school science curriculum standard(2017 edition),to improve the scientific literacy of primary school students.It is pointed out in the document that cultivating and improving the scientific literacy of primary school students is not only one of the main objectives of the primary school science curriculum,but also the basic requirement of the implementation of quality education.On the premise of grasping the relevant theories and policies,this study will take the construction of the primary school science textbook evaluation index system as the object,reference to the relevant literature,and improve the analysis process of the study by rigorous investigation.This study uses documentary study,delphi method,questionnaire survey,expert sorting and so on.Besides it employs spss20.0,Excel and other software to analyze the survey data.According to the process of "preliminary index--connotation analysis--multiple rounds of index screening--index reliability and validity analysis--teacher opinion analysis determining the weight system",a scientific and operable primary evaluation index system of scientific textbooks is formed.This study consists of six parts.By using the documentary study,this paper sorts out and analyzes the literature about textbook evaluation,science book evaluation and evaluation index system at home and abroad,This paper mainly completes the science textbook evaluation index system of primary school from the determination of evaluation purpose,preliminary conception of index system and connotation analysis;By using the delphi method to provide the semi-structured questionnaire about textbook evaluation to the experts,and according to the expert opinion to modify the evaluation index system of primary school science textbook and communicate with the relevant experts for many times,the paper finally establishes the evaluation index system of primary school science textbook with expert validity;Using questionnaire survey to understand teachers' views on the evaluation index system and the importance of indicators at all levels of primary school science textbooks,and based on the questionnaire data to analyze the reliability and validity of the evaluation index system of primary school science textbooks;the expert sorting method is used to analyze the questionnaire data,so as to determine the weight of each index,and finally it establish the weight index system about science textbook evaluation index of primary school;Taking the primary school science textbook of Qingdao edition as an example,according to the final established index system,the primary school science textbook is graded and compared with the analysis results of the first-line teachers to verify its feasibility;According to the established evaluation index system of elementary school science textbook,this paper analyzes the elementary school science textbook of Qingdao edition in order to test the operability of the evaluation index system of elementary school science textbook.Based on the overall analysis of the evaluation index system of primary school science textbooks,this study puts forward Suggestions on the compilation of primary school science textbooks and the implementation of primary school science curriculum according to the evaluation results of the Qingdao edition of primary school science textbooks.Based on the research contents,the conclusions are as follows: the evaluation index system of primary school science textbook constructed in this research is divided into three indicators,including three first-level indicators,six second-level indicators,29 third-level indicators and 31 specific standards;Through the internal consistency test and exploratory factor analysis of the importance data of teachers,it is concluded that the constructed evaluation index system has good reliability and validity.Experts and teachers maintain a high degree of agreement on the importance of indicators,it can be seen that the constructed evaluation index system has a certain degree of operability.
