中國高等教育學會“教育數學”專業委員會理事長致辭
作者: 點擊數:3119 更新時間:2013年7月1日 文章錄入:智慧數學
   

【編者按】數學的美蘊藏著至簡至和的智慧,數學的理性蘊藏著至真至通的智慧,數學的自由蘊藏著創造探索的智慧。

智慧數學,從改造教材開始,推進教育數學研究。“智慧數學”基于數學是一種智慧的感悟,基于數學教育追求學生智慧的生長。

什么是教育數學?李尚志先生在《中國高等教育學會教育數學專業委員會理事長致辭》中作了簡潔的回答。

中國高等教育學會“教育數學”專業委員會理事長致辭

李尚志

各位網友、老師、同學們:

我是中國高等教育學會教育數學專業委員會理事長。歡迎訪問本學會的網站,謝謝你關心并參與本學會的工作。

什么是教育數學?張景中院士用一句最簡單的話解釋了教育數學的宗旨:“改造數學使之更適宜于教學和學習,是教育數學為自己提出的任務。

從小學、中學到大學,數學都是學生最重要的課程,也是最困難的課程之一。困難的原因之一,可能是因為數學的真假有最明確的標準,一就是一,二就是二,知之為知之,不知為不知,最難蒙混過關。這是數學的優點,應當永遠堅持。但另一方面,是由于數學教學本身有問題,將本來生動精彩的數學講得枯燥乏味,本來威力無比的數學講得一無用處,使數學變成了令人讓學生討厭和仇恨的丑八怪和恐怖份子。于是,改進數學教學,幫助學生領略數學的精彩,利用和發揮數學的威力,就成為所有的數學教師和教育工作者義不容辭的職責。怎樣改進數學教學?教育學專家對于教學方式的改進有很多理論和辦法。而數學工作者和數學教師,則更多地是通過對數學內容的改造來改進教學,這就是教育數學。

雖然“教育數學”這個提法是張景中在1989年寫的《從數學教育到教育數學》一書中首次提出的,,但教育數學的活動卻是從來就有的。張景中舉了兩個例子:歐幾里得著《幾何原本》,柯西寫《分析教程》,都是“改造數學使之更適宜教學和學習”,都是教育數學。我想到另一個例子:伽羅瓦徹底解決了代數方程的求根公式和尺規作圖等問題,但他對自己的理論的敘述過于簡略,使當時最偉大的數學家都難以理解,直到劉維爾和約當等人理解了伽羅瓦的理論,重新加以闡述,才使這個理論更適宜教學和學習,開創了代數學的新時代。

“改造數學使之更適宜于教學和學習”是教育數學為自己提出的任務,也是提出“教育數學”的張景中為自己提出的任務。在數學教學改革中努力嘗試“改造數學使之更適宜于教學和學習”的數學工作者和數學教師,都是為實現這個任務而奮斗的志同道合者。2004年,在張景中院士主持下,一部分志同道合者組織起來,成立了中國高等教育學會教育數學專業委員會。在此之后,每年都有更多的志同道合者參加進來,交流和分享在研究和實踐教育數學中取得的成果,越來越多的學校和學生從中受益。

既然教育數學是對數學進行“改造”,本質上就是一種科學研究活動。與別的科研不同的是:這項研究的主要目的不是發明新的數學知識,而是將前人已經發明過的知識重新發明一遍,使之更容易教學和學習。既然是研究,就要求研究者對有深厚的數學功底,首先要保證研究方法和結果的正確無誤,又要比書本上的知識更容易懂,必定是前所未有的創新成果。科學研究成果只要保證正確性和創新性就行了,而教育數學的研究成果還必須讓學生易懂易學,這就要求研究者不僅要懂數學還要懂學生,了解學生的喜怒哀樂、接受能力和思維習慣。研究結果的成功與否,除了通過數學的標準來判別其正確性,還必須通過教學實踐來檢驗教學效果,看是否確實容易被學生接受。不同學校的學生的水平千差萬別,很難有一種方案同時適用于所有的學生,因此任何一種方案都不能唯我獨尊。反過來,任何一種方案,在保證科學上正確的前提下,只要確實能夠在一部分學生中取得好的教學效果,就值得嘗試和推廣。

歡迎所有關心數學教育的朋友參與我們的活動,分享經驗和成果。

不論你是哪一級學校的數學教師和教學工作者,不論你是否贊成我們已經研究出來的教學方案,只要有志于通過改造數學內容來改進數學教學,都歡迎參加本學會的組織。具體章程請查閱學會網站的相關信息。
