Characteristics Of Exercise Design In New Chemistry Textbook (Compulsory) For Senior High School And Research On The Current Situation Of Teaching

Under the influence of global economy,if a country wants to occupy a place in the international competition,it needs to gradually enhance its comprehensive national strength.As the core element in the competition of comprehensive national strength,cultural soft power plays an increasingly important role.As an important way of cultural communication,education has gradually become an important link in the competition of cultural soft power.At the same time,as the core of education and the product of the times,the importance of curriculum can be seen.Since the 21 st century,the development of international education keeps pace with the times,and the educational reform of various countries keeps on.In order to implement quality education and promote the improvement of the quality of basic education,China officially started the curriculum reform of senior high school in 2004.The development of education situation has put forward new requirements and challenges for middle school chemistry teaching.As the carrier of curriculum education,teaching material is an important part of school education and curriculum reform.In the field of science education,chemistry occupies an important position.How to speed up the pace of education reform,how to play the key role of Chemistry Teaching in guiding students' all-round development,how to reflect the traditional experimental,empirical and theoretical nature of contemporary chemistry development in teaching,how to teach basic knowledge and cultivate students' ability and improve students' quality in teaching content This is a problem that needs to be explored and solved in the development of modern chemistry teaching.The new curriculum reform of high school chemistry takes the students as the main body,combines the real needs of students' development in the teaching curriculum,gradually improves the comprehensive quality of students,and focuses on the future development of students,which puts forward new requirements for the research and compilation of high school chemistry textbooks.As an important part of teaching materials,exercises play an important role in consolidating students' knowledge and mastering knowledge.Through the exercises and the teacher's explanation of the exercises,students can not only increase their knowledge,but also cultivate their ability to analyze and solve problems.Some innovative questions can also help students develop their divergent thinking and innovative ability.At the same time,exercises can measure and evaluate the learning effect of students,and feed back the teaching information to teachers at the first time.Nowadays,our country is in the stage of innovation and optimization of basic education curriculum,one of the important ideas is to change the teaching content of "difficult,complex,partial,old",change the teaching methods,but if the chemistry teaching can not deal with the use of textbook exercises,it is difficult to play the role of exercises in teaching.Therefore,in-depth study of textbook exercises,a comprehensive understanding of the function and significance of textbook exercises in theory,study the compilation principles of textbook exercises,clear the application rules of textbook exercises,so that textbook exercises can really promote the development of chemistry teaching.While implementing the new curriculum reform,China needs to test the high school chemistry textbooks of people's Education Edition,Luko edition and Soviet education edition respectively,so as to judge whether these textbooks can meet the real needs of the new curriculum reform and the development of the times.Among the existing high school chemistry textbooks,the "people's Education Edition" published by the people's education press and the "Luke edition" published by Shandong science and Technology Press are used more frequently.An in-depth analysis of these textbooks can provide a reference for the research in relevant fields in China and have a certain reference value.Based on this situation,taking the people's Education Edition and Luke edition textbooks as examples,this paper makes a comparative analysis of the exercises of Luke edition and people's education edition textbooks from the surface and deep perspectives,in order to summarize the exercise design characteristics of the current edition textbooks.Combined with the interviews with senior high school chemistry teachers and the questionnaire of teachers and students using the new textbook,this paper studies the current situation of exercise teaching in the new textbook from the problems existing in the exercise teaching in the new textbook and some problems found in the exercise teaching,in order to find good methods and suggestions on exercise teaching.Through the research of this topic,we can further enrich the research content of textbook exercises,enhance teachers' understanding of curriculum standards and the overall grasp of textbook contents,accumulate practical experience for the compilation of textbook exercises,draw on the strengths of others,and give strong teaching suggestions for textbook exercises.
