Comparative Analysis Of Three Versions Of Chemistry Elective Textbooks In High School

In order to adapt to the rapid development of social economy and science and technology,curriculum reform is still ongoing.As one of the basic elements of classroom teaching,textbooks are not only the concretization of the content of curriculum standards,but also an important tool of teaching activities,and play a key role in the reform of education and teaching.At the same time,in order to cooperate with the reform of chemistry curriculum,educational researchers have also made corresponding changes in chemistry textbooks.Under the guidance of the policy of more than one syllabus,three different editions of the current experimental textbook "Experimental Chemistry"(optional)of the curriculum standard for senior high schools have their own characteristics in the clues and contents of the textbook and the presentation of the contents,which reflects the diversity of the arrangement of scientific knowledge under the guidance of the same curriculum standard.Firstly,this paper studies and collates the relevant research at home and abroad,and on this basis,makes a systematic comparative analysis of the three versions of experimental chemistry textbooks.The comparison of three versions of "Experimental Chemistry" mainly consists of three parts: firstly,based on the 2003 edition of "General Senior High School Chemistry Curriculum Standards(Experiments)",the paper compares the conformity of the three versions of teaching materials with the curriculum standards in core content,arrangement and presentation of content;secondly,it makes a detailed comparison of the specific contents of the three versions of teaching materials,including: The statistics and classification of the writing clues,number of experiments,column setting,illustrations and tables of the textbooks are summarized,and the similarities,differences,advantages and disadvantages of the three versions of Experimental Chemistry are summarized.Finally,the suggestions for the use and compilation of the three versions of the textbooks are put forward by comparing and analyzing the results.It is hoped that this study can provide teaching reference for front-line chemistry teachers,and then optimize the quality of teaching.At the same time,it can also provide research ideas for the compilation or secondary development of textbooks.
