| With the promulgation of the “Ordinary High School Mathematics Curriculum Standard(2017 Edition)”,the new textbook based on the curriculum standard has been put into use.Unlike the old textbook based on the “Ordinary High School Mathematics Curriculum Standard(Experiment)”,the new textbook is a set of new textbooks oriented by the core literacy of mathematics,so the textbook highlights the integration of curriculum content and core literacy.Because intuitive imagination literacy plays an important role in the core literacy system of mathematics,this paper interprets the old and new textbooks from the perspective of intuitive imagination literacy,and studies what changes have taken place in the new textbooks compared with the old textbooks?Do these changes highlight intuitive imagination? How to adjust teaching methods according to these changes to cultivate students’ intuitive imagination? This is of great significance to teachers’ teaching and students’ learning.Solid geometry is an important carrier of intuitive imagination literacy,and it is also the focus of previous mathematics curriculum reform.Therefore,this paper takes “solid geometry” as an example,starting from the macro and micro levels,compares and analyzes the 2004 edition and 2019 edition of Beijing Normal University,and draws the following conclusions:At the macro level,the new textbook has made great adjustments in the writing style of the two chapters of “parallel relationship and vertical relationship”.The adjusted arrangement order is more reasonable and the knowledge is more closely connected;on the basis of the old textbooks,“the nature of geometry”,“the concept of parallel hexahedron”,“the basic elements of space geometry” and so on are added,and the content of “three views” is deleted,aiming at making the knowledge system of solid geometry more perfect,so as to help students cultivate the concept of space and improve their understanding of knowledge.Three reading materials have also been added to improve students’ cultural literacy.In addition,the material of the new textbook is closer to the students’ life,providing geometric intuition,the column setting is more concise and refined,and the overall layout is clearer.At the micro level,from the perspective of the implicit emphasis of the various forms of intuitive imagination literacy,the new and old textbooks are more focused on the cultivation of “using geometric graphics to describe problems”,indicating that the new and old textbooks pay more attention to cultivating students’ ability to analyze and solve problems.From the perspective of the degree of implication of the various forms of intuitive imagination literacy,the old textbooks are mainly “using geometric graphics to describe problems”,and the new textbooks are mainly “using spatial imagination to understand things”.The degree of implication is higher,but the degree of implication of the new textbook is higher than that of the old textbook,indicating that the new textbook highlights the integration of solid geometry content and intuitive imagination literacy.Finally,combined with the research content and the interview results of front-line teachers,this paper puts forward some teaching strategies for how to cultivate students’ intuitive imagination literacy under the new textbook solid geometry content:(1)Cultivate the concept of space and improve the ability of logical reasoning;(2)Cultivate spatial imagination ability and infiltrate mathematical thinking methods;(3)Make rational use of information technology and cultivate intuitive imagination literacy;(4)Strengthen drawing training,inspire intuitive imagination;(5)Infiltrating mathematical culture and improving cultural literacy. |
