A Comparative Study Of Some Functions In The New High School Mathbook Under The Key Competences

Education is the cornerstone of national rejuvenation,while textbook is the materialization of education,it is very important.By comparing different versions of textbooks and combining the core qualities,finding out the common and divergent points of disparate edition of textbooks is conducive to teachers to preferably comprehend and use the teaching materials,and preferably foster "comprehensive ability".This article chooses the substance of function in the textbooks of PEP A version published in 2019 and BNU verdion published in 2019,application systems and study methods,this article contrasts the two books in terms of it past records in the course of change and development,compiling structure of substances,foster setup,peculiarity of textbooks and the parallel of core literacy and textbooks,so we can receive the advantages and disadvantages of PEP A and BNU teaching material,assistance mentors and pupils to make better to use of the new textbooks,elevate the quality of learning,and also provide some suggestions for the reformulation of function substance.Research indicates:1.On the basis of their old versions,the overall structure of chapters and the arrangement of local knowledge points have been adjusted in both versions,which keep on the good part of the last textbook,simultaneously,we also make great efforts to blaze new trails the concept of the contemporary age curriculum,integrate it with the era,make teaching materials easy to teaching and learning.2.There are some variation in the pertaining to learning or culture fix up the new edition textbooks function verse,but they lay stress on the piece together of thinking and the incarnation of math thinking methods,and form theirselves distinguishing feature on the basis of Innovation-driven development.3.Both versions of the textbook have their own advantages in column setting,text structure,illustrations,expanded columns,etc.,but on the whole,the A version of the textbook is more abundant in surface structure setting,reflecting more levels of mathematical literacy.In terms of degree of difficulty of simulation system,PEP A version puts forth effort on the refinement of talents with comprehensive capacity in math,while BNU version lay emphasis on the foster of seat capability.4.In terms of the core literacy of the function content in the two versions of textbooks,PEP A lay emphasis on the foster of pupils' logical inferernces and mathematical modeling attainment,and appears more time as well;BNU version lay stress on the foster of students' basic ability,in addition lay emphasis on the organic intergrate of core attainment and senior middle school mathematics substance.
