A Study On The Use Of "Chapter Introduction" In The New High School Chemistry Textbook Of People’s Education Press

With the development of society,the demand for talents is getting higher and higher.In order to meet this demand for talents,curriculum reform has been promoted and textbooks have been innovated.Since the new curriculum reform in 1993,the textbook has added a "chapter introduction" before each chapter.The "Chapter Introduction" of the latest version of the textbook has been improved and optimized compared with the previous one,which is more knowledgeable,methodical and instructive."The chapter introduction is one of the important components of secondary school chemistry textbooks,but it was found from literature research and interviews that it was neglected by many teachers in the actual teaching process,which made the good intention of the textbook writers a waste.Based on this,this paper selects the chapter introductions in the new high school chemistry textbook of the Human Education version as the research object,investigates and analyzes the reasons why teachers ignore the use of chapter introductions and the factors that affect the use of chapter introductions,and based on the characteristics of "chapter introductions",proposes a specific and feasible teaching idea around "chapter introductions"The first part points out the background,research questions and significance of this paper,as well as the research ideas and methods;the second part analyzes the current situation of the research on "chapter introduction",including what is chapter introduction,the research situation of chapter introduction and the analysis of its characteristics,and the analysis of the characteristics of chapter introduction in the new high school chemistry textbook through the horizontal and vertical comparison of textbooks.The third part is to investigate the current situation of chapter introductions in high school chemistry textbooks through text analysis and questionnaires;the fourth part is to propose a teaching strategy.This paper consists of four parts.The first part points out the background,research questions and significance of this paper,as well as the research ideas and methods;the second part analyzes the current situation of the research on "chapter introduction",including what is chapter introduction,the research situation of chapter introduction and the analysis of its characteristics,and the horizontal and vertical comparison of textbooks.In the third part,the current situation of chapter introductions in high school chemistry textbooks is investigated through text analysis and questionnaires.The fourth part is to propose a teaching strategy,which focuses on the characteristics of "chapter introduction",taking "big idea" as a bridge and using"big unit teaching" to find a landing point for its use.After the theoretical justification,the feasibility of the "large unit on metals" is demonstrated in teaching practice through the development and practice of teaching casesBased on the above study,it can be concluded that:1.the chapter introduction is the introduction before each chapter of the textbook,which plays the role of opening and outlining.2.The "chapter introduction" in the new high school chemistry textbook can clarify the core knowledge,guide the learning direction,reflect the basic concept of the new curriculum standards,and has teaching and research value.3.In the actual education and teaching,the use rate of chapter introduction is low and simple,most teachers are aware of the importance of chapter introduction,the main reason for the low use rate of chapter introduction is that it is not tested in the college entrance examination.4.The author uses large units of teaching on chapter quotation for teaching research,from the results of the study,the results of teaching practice is feasible,teachers and students pay attention to improve.
