教育部考試中心以正式文件明確提出在高考數(shù)學(xué)考題中要體現(xiàn)數(shù)學(xué)文化,這是一個(gè)明顯的信號(hào):要求學(xué)生加強(qiáng)對(duì)數(shù)學(xué)文化知識(shí)的學(xué)習(xí),自覺(jué)地、有針對(duì)性地重視對(duì)數(shù)學(xué)文化修養(yǎng)的提升。
本書(shū)創(chuàng)新性地從以數(shù)化人與人數(shù)學(xué)化兩個(gè)角度來(lái)談數(shù)學(xué)文化,對(duì)數(shù)學(xué)文化在數(shù)學(xué)歷史、數(shù)學(xué)精神、數(shù)學(xué)應(yīng)用、數(shù)學(xué)之美、數(shù)學(xué)語(yǔ)言、交匯拓展、數(shù)學(xué)游戲等各個(gè)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(jié)合歷年高考數(shù)學(xué)試題進(jìn)行具體的案例分析,以此讓高考生能夠精準(zhǔn)消化吸收高考中的各種數(shù)學(xué)文化知識(shí)。
對(duì)高中生而言,這是一部讓他們明確數(shù)學(xué)文化是什么怎么考怎么練,為備考數(shù)學(xué)文化提供清晰學(xué)習(xí)方向的紅寶書(shū);對(duì)數(shù)學(xué)教學(xué)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(guò)程、凸顯數(shù)學(xué)文化價(jià)值的寶貴內(nèi)參書(shū);對(duì)于廣大的數(shù)學(xué)文化愛(ài)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(xué)美書(shū)。
★為什么要學(xué)習(xí)數(shù)學(xué)文化?其實(shí)這個(gè)問(wèn)題也等同于為什么要學(xué)習(xí)數(shù)學(xué)。數(shù)學(xué)本身就是一種文化,所以這本書(shū)旨在幫助學(xué)生形成良好的數(shù)學(xué)思維能力,掌握解決問(wèn)題的方法,培養(yǎng)理性精神。
★現(xiàn)在的高考試題越來(lái)越注重考生解決問(wèn)題的能力,倘若只會(huì)刷題而不能理解題中真意將會(huì)寸步難行。本書(shū)以文化為內(nèi)核,將理論、方法、歷史、文化融為一體,知識(shí)性、趣味性和實(shí)操性完美結(jié)合。
★數(shù)學(xué)家顧沛高度贊賞的數(shù)學(xué)文化典范之作,中國(guó)科學(xué)院院士陳佳洱、王大中聯(lián)袂誠(chéng)意推薦,適合高中生及教學(xué)工作者使用。
2016
年10 月8 日,教育部考試中心下發(fā)《關(guān)于2017 年普通高考考試大綱修訂內(nèi)容的通知》(教試中心函〔2016〕179 號(hào)),增加了數(shù)學(xué)文化的要求。這一文件的公布,引發(fā)了社會(huì)對(duì)數(shù)學(xué)文化的極大關(guān)注,成為教育界的熱門(mén)話題。
事實(shí)上,當(dāng)人們不滿足于對(duì)數(shù)學(xué)本身的研究,開(kāi)始從外部審視數(shù)學(xué)的價(jià)值時(shí),對(duì)數(shù)學(xué)文化的研究就開(kāi)始了。人們開(kāi)始思考數(shù)學(xué)是什么與數(shù)學(xué)的價(jià)值是什么,并逐漸認(rèn)識(shí)到數(shù)學(xué)已經(jīng)成為人類文化的重要組成部分,在過(guò)去已經(jīng)對(duì)人類文明做出了巨大的貢獻(xiàn),在未來(lái)也必將做出更大的貢獻(xiàn)。
把數(shù)學(xué)作為文化來(lái)進(jìn)行研究,國(guó)外要比我們?cè)绾芏,比較有代表性的是美國(guó)的數(shù)學(xué)家懷爾德與數(shù)學(xué)史專家莫里斯·克萊因。懷爾德認(rèn)為數(shù)學(xué)是一個(gè)由內(nèi)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(xué)文化是由文化傳統(tǒng)和數(shù)學(xué)本身所組成。這些觀點(diǎn)在他的兩部著作《數(shù)學(xué)概念的演化》和《作為一種文化系統(tǒng)的數(shù)學(xué)》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(xué)》《數(shù)學(xué):一種文化探索》《數(shù)學(xué)與知識(shí)的探求》中則系統(tǒng)論述了數(shù)學(xué)對(duì)西方文化、理性精神、現(xiàn)代人類思想發(fā)展所產(chǎn)生的影響。他側(cè)重于數(shù)學(xué)與各種文化以及社會(huì)因素之間相互作用的分析。我國(guó)開(kāi)展數(shù)學(xué)文化研究是近二三十年的事情,時(shí)間雖短,但是相關(guān)研究也取得了極大進(jìn)展。徐利治探討數(shù)學(xué)一般意義上存在的某些相同或不同的方法,開(kāi)創(chuàng)了數(shù)學(xué)方法論的研究與教學(xué);鄭毓信教授在他的《數(shù)學(xué)文化學(xué)》中基于數(shù)學(xué)哲學(xué)觀點(diǎn)構(gòu)建數(shù)學(xué)文化學(xué)的理論體系,嘗試從理論層面論述數(shù)學(xué)作為文化的內(nèi)涵;齊民友在《數(shù)學(xué)與文化》一書(shū)中則論述了中西數(shù)學(xué)文化的差異。
我國(guó)教育主管部門(mén)對(duì)數(shù)學(xué)文化也很重視。早在2003 年,教育部頒布的《普通高中數(shù)學(xué)課程標(biāo)準(zhǔn)(實(shí)驗(yàn))》中就突出強(qiáng)調(diào)了數(shù)學(xué)的文化價(jià)值數(shù)學(xué)是人類文化的重要組成部分,對(duì)數(shù)學(xué)文化給予了特別重視,要求數(shù)學(xué)文化貫穿整個(gè)高中數(shù)學(xué)課程并融入教學(xué)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(duì)數(shù)學(xué)文化重點(diǎn)提及,明確提出要在高考試題中考查數(shù)學(xué)文化,足以看出國(guó)家對(duì)數(shù)學(xué)文化的重視。
以往提及數(shù)學(xué)文化,大多停留在理論的層面,而且很多研究?jī)H僅把史實(shí)、案例、故事等稍作整理,將數(shù)學(xué)史等同于數(shù)學(xué)文化。這種做法不過(guò)是給數(shù)學(xué)文化穿了件數(shù)學(xué)史外衣而已。類似的研究總給人以不接地氣之嫌,沒(méi)有引起人們的觸動(dòng)。但這次之所以引發(fā)對(duì)數(shù)學(xué)文化思考與研究的熱潮,主要原因是考試主管部門(mén)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(xué)文化滲入數(shù)學(xué)試題,所以未來(lái)高考數(shù)學(xué)命題肯定會(huì)遵照?qǐng)?zhí)行。雖然我們提了很久的數(shù)學(xué)文化,但如何在數(shù)學(xué)試題中體現(xiàn)出來(lái),對(duì)很多人來(lái)說(shuō)還是比較陌生的。數(shù)學(xué)文化本來(lái)是個(gè)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(xué)是邏輯的科學(xué)、思維的科學(xué),如何把文化滲透其中,是一個(gè)擺在廣大數(shù)學(xué)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(shū),對(duì)相關(guān)問(wèn)題作出了系統(tǒng)的回答。
《高考中的數(shù)學(xué)文化》一書(shū)共分八章。第一章為數(shù)學(xué)文化總論,主要闡述了數(shù)學(xué)文化的含義、內(nèi)容和基本特性等問(wèn)題;后面七章分別為數(shù)學(xué)歷史、數(shù)學(xué)精神、數(shù)學(xué)應(yīng)用、數(shù)學(xué)之美、數(shù)學(xué)語(yǔ)言、交匯拓展、數(shù)學(xué)游戲,遴選近十五年高考數(shù)學(xué)中涉及數(shù)學(xué)文化的試題進(jìn)行分類賞析,系統(tǒng)揭示命制背景,展示解題過(guò)程,凸顯數(shù)學(xué)文化價(jià)值。全書(shū)盡可能把數(shù)學(xué)文化出題的方向一網(wǎng)打盡,讓讀者明確數(shù)學(xué)文化是什么怎么考怎么練,為備考數(shù)學(xué)文化提供清晰的復(fù)習(xí)方向。同時(shí)每個(gè)主題后面提供與主題相關(guān)的數(shù)學(xué)文化練習(xí)題,方便讀者練習(xí)鞏
固使用,從而更有針對(duì)性地復(fù)習(xí)。本書(shū)的編寫(xiě)具有實(shí)用性、針對(duì)性和時(shí)效性三個(gè)鮮明特點(diǎn),密切結(jié)合當(dāng)下學(xué)生、教師對(duì)數(shù)學(xué)文化試題認(rèn)識(shí)相對(duì)陌生的客觀實(shí)際,對(duì)高考中曾經(jīng)出現(xiàn)的數(shù)學(xué)文化試題進(jìn)行分類賞析,系統(tǒng)闡述最新考綱考查數(shù)學(xué)文化的內(nèi)涵,同時(shí)為學(xué)生備考提供科學(xué)性的建議。
我國(guó)對(duì)數(shù)學(xué)文化的系統(tǒng)研究時(shí)間不長(zhǎng),尤其是數(shù)學(xué)文化與試題的結(jié)合研究更是不成熟。此書(shū)盡管對(duì)數(shù)學(xué)文化的理論探討與應(yīng)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(shū)的問(wèn)世將會(huì)受到廣大同行的重視和學(xué)生的歡迎。在此,我也懇請(qǐng)讀者批評(píng)雅正。
