| The promulgation of "General High School Mathematics Curriculum Standards(2017Edition)" has opened a new prelude to the reform of high school mathematics curriculum.It puts Lide Shuren as the fundamental task of education,and injected new vitality into the concept of high school mathematics education.Textbooks are the main carrier of new curriculum goals and educational concepts.The logical structure of textbooks and the compilation quality of knowledge content have a direct impact on the success or failure of the implementation of curriculum reforms.Different versions of textbooks will show different characteristics,have different requirements,and will have different impacts on textbook users.In order to help users of textbooks conduct objective and scientific analysis of textbooks,understand the changes in the new textbooks and the characteristics of the new textbooks,and promote the common development of teaching and learning.This study summarizes the research status of the four aspects of "core literacy of high school mathematics","high school mathematics curriculum standards","comparison of high school mathematics textbooks",and "comprehensive difficulty of textbooks" by studying published literature,and clarifies the scope of this research.And key points;then,from the aspects of "curriculum concept and objectives","knowledge distribution","learning and training system(problem scenarios,presentation method of sample questions,method of setting exercises)","difficulty of sample exercises and comprehensive difficulty of textbooks",the old and new The textbooks were qualitatively described and quantitatively analyzed;finally,a questionnaire was designed based on the research results to investigate the use of new and old textbooks by frontline teachers and their views on the new textbooks.Combining the views of frontline teachers,it was proposed to train students in the teaching process of using the new textbooks.Recommendations for core literacy.The research found that:(1)The new textbook pays more attention to the connection of mathematics knowledge between junior and senior high schools.Through the adjustment of the order of knowledge,the characteristic of spiraling content is more obvious,which is in line with the law of students’ cognitive development.(2)By selecting materials and examples with the characteristics of the new era,the new textbook incorporates more information technology application cases,which more reflects the contemporary and practicality of mathematical content,and emphasizes by adding function application cases and setting mathematical modeling topics.Cultivation of mathematics application consciousness.(3)The new textbooks pay more attention to the application value and educating value of mathematics knowledge,and intends to guide students to actively pay attention to the society,continuously develop the core literacy of students in the learning process,and give full play to the role of mathematics education.(4)The knowledge breadth and depth of the function part of the old textbook are 41 and 88,respectively,and the knowledge breadth and depth of the function part of the new textbook are 43 and 87 respectively,with little change;according to the comprehensive difficulty coefficient model,the function part of the old textbook and the new textbook The difficulty of the exercises is 11.32 and 12.28,and the comprehensive difficulty of the function part of the new textbook is 1.44 and 1.68 respectively.It can be clearly seen that the difficulty of the function part of the new textbook has increased.(5)In the survey,more than 70% of teachers were satisfied with the changes to the new textbooks,but teachers did not pay enough attention to mathematical modeling in teaching,lacked the training of mathematics application awareness and ability,and ignored the pressure of exams.The additional content of the textbook still exists.Based on the research conclusions,the suggestions made are:(1)Teachers should strengthen the study of the two editions of textbooks,clarify the differences and characteristics of the two textbooks,inherit the advantages of the old textbooks,and carry forward the innovations of the new textbooks.(2)In actual teaching,teachers can carry out secondary development of teaching materials,use current hot spots as mathematics scenarios,guide students to actively pay attention to social development,promote the formation of students’ good character,implement the task of cultivating people.(3)In teaching,teachers not only pay attention to the improvement of students’ scores on the face,but also pay attention to applying what they have learned,and pay attention to cultivating students’ awareness and ability of mathematics application. |
