A Comparative Study Of New And Old Versions Of High School Chemistry Textbooks Based On The Core Compentence Of Disciplines

At present,high-quality talents have become a key factor for a country and a nation to enhance its comprehensive national strength.There is no doubt that the improvement of the quality of education is the main way to train high-quality talents at all levels,and the improvement of the quality of basic education is one of the important links.Therefore,under the current background of rapid knowledge update and the continuous development of the information society,it is of great significance to continuously promote and improve the reform of the curriculum system and comprehensively develop quality education.In recent years,successively developed curriculum standards based on the core literacy of various disciplines have further promoted the construction of teaching materials and the improvement of quality education.At the same time,each chemistry textbook writing group started the compilation of high school chemistry textbooks in accordance with the concepts and requirements of the General High School Chemistry Curriculum Standards(2017 Edition),and successively published several new sets of high school chemistry textbooks.In order to better analyze the teaching materials and select the teaching materials,make full use of the advantages of different versions of the teaching materials,and better adapt to the requirements of developing the core literacy of the students' chemistry disciplines,this paper based on the literature research and combining their own teaching experience,the People's Education Edition was published in 2004.And "common inorganic substances and their applications" in two sets of high school chemistry textbooks published in 2019 as the theme,to study them,using methods such as literature analysis,questionnaire surveys,statistics and text analysis to use the theme in the old textbooks To investigate the current situation,in view of some shortcomings of the published textbooks in 2004,combined with the concept of the new curriculum,from the macro and micro dimensions,the new and old textbooks are compared,and it is expected that the first-line teachers will better choose new textbooks and better Provide some references and suggestions for local teaching.Through the investigation and study of teachers and students,it is found that the old textbooks have the following problems:(1)Compulsory 1 has large knowledge capacity and difficult points;(2)There are few experiments on the textbooks,and they have not received the attention they deserve in daily teaching;(3)Due to the influence of teaching materials,some teachers put too much emphasis on professional knowledge and neglect the cultivation of students' abilities.Through a comparative analysis of the two editions of textbooks before and after revision,it is found that the core literacy characteristics of the new textbooks of the People's Education Edition are more prominent,and more attention is paid to the improvement of students' abilities.It is reflected in the following aspects: from the perspective of the chapter layout structure,the new version of the textbook combines "basic concepts and theories of chemistry,elements and their compounds,chemistry and social development".The difficulty of knowledge gradually increases,and it is more scientific and reasonable than the old textbook;In terms of presentation methods,the new version of the textbook focuses on the use of charts,and the column design is more flexible.From the perspective of the selection of specific element compounds,the new version of the textbook reduces the systematic understanding of aluminum,silicon and copper,and increases the sodium,iron,chloride,sulfur,nitrogen five core elements of compound knowledge and capacity requirements.The understanding requirements and ability requirements have also significantly improved the ability requirements of related basic chemical concepts and theoretical transfer applications.According to the above survey and text analysis,combined with the development requirements of the core literacy of the chemistry discipline,in the teaching of the topic of "Common Inorganics and Their Applications",I tried to make the following suggestions: First,in-depth analysis of curriculum standards and textbooks to reasonably grasp the depth of knowledge Breadth;Second,pay attention to the connection and synthesis of knowledge to improve students' problem-solving ability;Third,encourage students to explore and cooperate with themselves to update the changes in student training model;Fourth,make good use of columns and give full play to the functions of the columns.
