教育部考試中心以正式文件明確提出在高考數(shù)學考題中要體現(xiàn)數(shù)學文化,這是一個明顯的信號:要求學生加強對數(shù)學文化知識的學習,自覺地、有針對性地重視對數(shù)學文化修養(yǎng)的提升。
本書創(chuàng)新性地從以數(shù)化人與人數(shù)學化兩個角度來談數(shù)學文化,對數(shù)學文化在數(shù)學歷史、數(shù)學精神、數(shù)學應用、數(shù)學之美、數(shù)學語言、交匯拓展、數(shù)學游戲等各個主題上都作出了全面透徹的剖析和論述。除此之外,作者還結合歷年高考數(shù)學試題進行具體的案例分析,以此讓高考生能夠精準消化吸收高考中的各種數(shù)學文化知識。
對高中生而言,這是一部讓他們明確數(shù)學文化是什么怎么考怎么練,為備考數(shù)學文化提供清晰學習方向的紅寶書;對數(shù)學教學工作者或研究者而言,這是一部系統(tǒng)揭示命制背景、展示解題過程、凸顯數(shù)學文化價值的寶貴內參書;對于廣大的數(shù)學文化愛好者而言,這又是一部讓人崇尚真理,凈化心靈,提升文化修養(yǎng)和文化品格的數(shù)學美書。
★為什么要學習數(shù)學文化?其實這個問題也等同于為什么要學習數(shù)學。數(shù)學本身就是一種文化,所以這本書旨在幫助學生形成良好的數(shù)學思維能力,掌握解決問題的方法,培養(yǎng)理性精神。
★現(xiàn)在的高考試題越來越注重考生解決問題的能力,倘若只會刷題而不能理解題中真意將會寸步難行。本書以文化為內核,將理論、方法、歷史、文化融為一體,知識性、趣味性和實操性完美結合。
★數(shù)學家顧沛高度贊賞的數(shù)學文化典范之作,中國科學院院士陳佳洱、王大中聯(lián)袂誠意推薦,適合高中生及教學工作者使用。
2016
年10 月8 日,教育部考試中心下發(fā)《關于2017 年普通高考考試大綱修訂內容的通知》(教試中心函〔2016〕179 號),增加了數(shù)學文化的要求。這一文件的公布,引發(fā)了社會對數(shù)學文化的極大關注,成為教育界的熱門話題。
事實上,當人們不滿足于對數(shù)學本身的研究,開始從外部審視數(shù)學的價值時,對數(shù)學文化的研究就開始了。人們開始思考數(shù)學是什么與數(shù)學的價值是什么,并逐漸認識到數(shù)學已經成為人類文化的重要組成部分,在過去已經對人類文明做出了巨大的貢獻,在未來也必將做出更大的貢獻。
把數(shù)學作為文化來進行研究,國外要比我們早很多,比較有代表性的是美國的數(shù)學家懷爾德與數(shù)學史專家莫里斯·克萊因。懷爾德認為數(shù)學是一個由內在力量與外在力量共同作用,而處于不斷發(fā)展和變化之中的文化系統(tǒng)。數(shù)學文化是由文化傳統(tǒng)和數(shù)學本身所組成。這些觀點在他的兩部著作《數(shù)學概念的演化》和《作為一種文化系統(tǒng)的數(shù)學》中得以充分體現(xiàn)。莫里斯·克萊因在他的著作《西方文化中的數(shù)學》《數(shù)學:一種文化探索》《數(shù)學與知識的探求》中則系統(tǒng)論述了數(shù)學對西方文化、理性精神、現(xiàn)代人類思想發(fā)展所產生的影響。他側重于數(shù)學與各種文化以及社會因素之間相互作用的分析。我國開展數(shù)學文化研究是近二三十年的事情,時間雖短,但是相關研究也取得了極大進展。徐利治探討數(shù)學一般意義上存在的某些相同或不同的方法,開創(chuàng)了數(shù)學方法論的研究與教學;鄭毓信教授在他的《數(shù)學文化學》中基于數(shù)學哲學觀點構建數(shù)學文化學的理論體系,嘗試從理論層面論述數(shù)學作為文化的內涵;齊民友在《數(shù)學與文化》一書中則論述了中西數(shù)學文化的差異。
我國教育主管部門對數(shù)學文化也很重視。早在2003 年,教育部頒布的《普通高中數(shù)學課程標準(實驗)》中就突出強調了數(shù)學的文化價值數(shù)學是人類文化的重要組成部分,對數(shù)學文化給予了特別重視,要求數(shù)學文化貫穿整個高中數(shù)學課程并融入教學中。這次教育部考試中心又再次以發(fā)布正式文件的方式對數(shù)學文化重點提及,明確提出要在高考試題中考查數(shù)學文化,足以看出國家對數(shù)學文化的重視。
以往提及數(shù)學文化,大多停留在理論的層面,而且很多研究僅僅把史實、案例、故事等稍作整理,將數(shù)學史等同于數(shù)學文化。這種做法不過是給數(shù)學文化穿了件數(shù)學史外衣而已。類似的研究總給人以不接地氣之嫌,沒有引起人們的觸動。但這次之所以引發(fā)對數(shù)學文化思考與研究的熱潮,主要原因是考試主管部門從考試命題的角度提出了要求,第一次正式地明確要求把數(shù)學文化滲入數(shù)學試題,所以未來高考數(shù)學命題肯定會遵照執(zhí)行。雖然我們提了很久的數(shù)學文化,但如何在數(shù)學試題中體現(xiàn)出來,對很多人來說還是比較陌生的。數(shù)學文化本來是個籠統(tǒng)的概念,傳統(tǒng)意義上文化在文科中出現(xiàn)得較為普遍,在文科類的命題中是很容易做到的。而數(shù)學是邏輯的科學、思維的科學,如何把文化滲透其中,是一個擺在廣大數(shù)學教育工作者面前的新課題。正是在這樣的背景下,我根據(jù)多年積累的豐富資料和大量的研究工作,捉筆成書,對相關問題作出了系統(tǒng)的回答。
《高考中的數(shù)學文化》一書共分八章。第一章為數(shù)學文化總論,主要闡述了數(shù)學文化的含義、內容和基本特性等問題;后面七章分別為數(shù)學歷史、數(shù)學精神、數(shù)學應用、數(shù)學之美、數(shù)學語言、交匯拓展、數(shù)學游戲,遴選近十五年高考數(shù)學中涉及數(shù)學文化的試題進行分類賞析,系統(tǒng)揭示命制背景,展示解題過程,凸顯數(shù)學文化價值。全書盡可能把數(shù)學文化出題的方向一網(wǎng)打盡,讓讀者明確數(shù)學文化是什么怎么考怎么練,為備考數(shù)學文化提供清晰的復習方向。同時每個主題后面提供與主題相關的數(shù)學文化練習題,方便讀者練習鞏
固使用,從而更有針對性地復習。本書的編寫具有實用性、針對性和時效性三個鮮明特點,密切結合當下學生、教師對數(shù)學文化試題認識相對陌生的客觀實際,對高考中曾經出現(xiàn)的數(shù)學文化試題進行分類賞析,系統(tǒng)闡述最新考綱考查數(shù)學文化的內涵,同時為學生備考提供科學性的建議。
我國對數(shù)學文化的系統(tǒng)研究時間不長,尤其是數(shù)學文化與試題的結合研究更是不成熟。此書盡管對數(shù)學文化的理論探討與應用研究取得了較大突破,然而也不免出現(xiàn)不完善或者紕漏之處。但我相信,此書的問世將會受到廣大同行的重視和學生的歡迎。在此,我也懇請讀者批評雅正。
