Analysis Of High School Chemistry Textbooks With A “student-centered” Orientatio

With the promulgation and implementation of Chemistry Curriculum Standards for Ordinary Senior High Schools(2017 Edition),various versions of chemistry textbooks as a product of the curriculum reform have mushroomed out one after another.At present,the new edition of general high school chemistry textbook for human education has been widely used.It bears the important mission of developing students’ chemistry core literacy,which essentially belongs to people.Therefore,does the new textbook carry out the educational concept of "student-centered" ? How does it embody "student-centered" ? This issue is very important and directly determines the achievement of the core literacy goal.In order to ensure that textbooks carry out the concept of curriculum reform and develop students’ chemistry core literacy,it is of certain practical value to analyze textbooks.This study establishes a "student-centered" textbook evaluation index system,revises the evaluation index through empirical research,constructs a "student-centered" textbook analysis framework,and analyzes chemistry textbooks with content analysis method.Firstly,the textbook content research,textbook content analysis methods and student-centered literature from the perspective of core literacy are collected and reviewed,and the basic laws of students’ learning are extracted by combining relevant theories and research results of learning science,and the "student-centered" textbook evaluation index is preliminarily obtained.Secondly,taking the established evaluation index system as the framework and combined with the research needs,the interview outline is prepared.Adopt the method of semi-structured interview was measured,the three college chemistry teaching from provincial colleges and universities of professional teachers,and from this province provincial standardization school grade three front-line teachers,five students with semi-structured interview,modified evaluation index,eventually form 4 first-level indicators,16 secondary indexes of chemistry textbook evaluation system.Then,based on the obtained analysis framework,taking two textbooks,Volume 1 and Volume 2,which are compulsory for senior high school chemistry published by People’s Education Publishing House,as the research objects,the system structure and content presentation of the textbooks are surveyed respectively.Finally,the results of the new textbook’s student-centered education concept are obtained,and some suggestions on the use of teachers’ textbooks and the compilation of textbooks are put forward.The results show that:(1)People’s Education Edition chemistry textbooks pay attention to the design of "student-centered";(2)The content design focuses on the major concepts of the discipline,with special emphasis on "supporting integrated reasoning";(3)There is still room for optimization and improvement in the content design of textbooks.The innovations of the research:(1)The "student-centered" analysis framework of chemistry textbook provides a new tool for textbook survey;(2)This paper summarizes the implementation results of the new chemistry textbook "student-centered",which provides a basis for teachers to better understand and use the textbook.
