今年全国各省、市中考数学题的一个显著特点是加强了数学与其它学科的横向联系.在中考对学生适应跨学科知识渗透的综合能力的考查中,不仅体现了数学在各科中的“工具性”作用,而且符合我国课程改革的方向.因此以其它学科知识为背景和题材,将数学融入其它学科,用数学知识和方法解决其它学科的问题是当今中考命题的主流与热点.其它学科中的问题可利用数学中的方程、函数、图象、几何定理,数的表示法等知识及配方法、待定系数法等方法来解答.这些题既有定量计算,也有定性分析.
A notable feature of this year’s provincial and municipal exam math problems is that it has strengthened the horizontal connection between mathematics and other disciplines. In the examination of students’ comprehensive ability to adapt to cross-disciplinary knowledge penetration, not only the “tools of mathematics in various subjects” “Sex” effect, but also in line with the direction of curriculum reform in China. Therefore, using other subject knowledge as a background and subject matter, integrating mathematics into other disciplines, using mathematics knowledge and methods to solve problems in other disciplines is the mainstream and focus of today’s test proposition. In other disciplines The problems can be solved by using mathematical equations, functions, images, geometric theorems, number representations and other knowledge and matching methods, undetermined coefficient methods, etc. These questions have both quantitative and qualitative analysis.
