Research On The Transformation Of The Compulsory Contents Of The Old And New Pep Edition Of High School Chemistry Textbooks

Under the background of the new curriculum reform,the focus of the chemistry curriculum reform is to improve students' Chemical key competence.Chemistry textbooks are the important carriers for achieving the goal of high school chemistry courses and cultivating students' core chemistry literacy.Therefore,the reform of chemistry textbooks is also a new course.The focus of the reform is that new chemistry textbooks for human textbooks are officially published in 2019.Studying the conversion of old and new chemistry textbooks is of great significance to help teachers analyze and make better use of chemistry textbooks.The latest two high school chemistry compulsory textbooks of the PEP edition high school are taken as the research object(the high school chemistry textbooks of the PEP edition,the 2019 edition as the new textbooks,and the 2007 edition as the old textbooks)in this research.The research background,relevant concepts and theoretical basis have been summarized by the study of literature and comprehensive analysis;the compulsory content of the new and old textbook chemistry textbooks have been summarized by the study of the text analysis method;the comparative research method is used to study the transformation of the compulsory content of the high school chemistry textbooks used by the new and old PEP edition,Including the translation of the new and old high school textbooks on the content and presentation of the text(column settings,text length,illustrations,catalogs,appendices and covers)for research.Finally,some features of the new high school chemistry textbook and some suggestions on how to use the new chemistry textbook have been summarized through the transformation research on the compulsory content of senior high school chemistry textbooks.According to the research,the compulsory content of the new senior high school PEP edition chemistry textbooks is written around the Chemical key competence,which is different from the old textbooks.Teachers could be able to reasonably use the new version of the textbooks and take advantage of the new version textbooks after knowing the content of the new and old versions of the textbook.
