【正文】 hows that: the variant teaching in training students39。本文在相關文獻綜述的基礎上結合教學實際和自己的經(jīng)驗,在不等式教學的基礎上進行研究,通過課堂實驗和問卷的調(diào)查得出相關結論。因此,從不等式入手研究數(shù)學變式教學有著重要的現(xiàn)實意義。在高中數(shù)學中不等式的性質是基礎,其性質和解法在其他知識的領域中應用較為廣泛,如函數(shù)的定義域、單調(diào)性、最值、復數(shù)等等。最后,通過實例表明了:變式教學在培養(yǎng)學生抽象、具體、求逆、分解、組合、類比等數(shù)學思維具有一定的作用,從而為進一步研究變式教學提出展望。其次,在已有研究的基礎上,闡述了變式和變式教學的涵義,比較系統(tǒng)地歸納了變式教學的理論依據(jù):有意義學習的理論、馬登的變異理論、最近發(fā)展區(qū)理論、腳手架理論。變式教學對幫助學生理解知識含義、熟悉數(shù)學方法、明了知識之間的聯(lián)系、總結數(shù)學規(guī)律、提高數(shù)學能力都具有積極的意義。作者簽名: 日期: 年 月 日導師簽名: 日期: 年 月 日 摘 要現(xiàn)行的變式教學是我國中學數(shù)學教學的一個重要特色,所謂變式,就是從多方面變更所提供材料或問題呈現(xiàn)的形式,使事物非本質特征時隱時現(xiàn),而事物的本質特征卻保持不變的變化方式。本人授權      大學可以將本學位論文的全部或部分內(nèi)容編入有關數(shù)據(jù)庫進行檢索,可以采用影印、縮印或掃描等復制手段保存和匯編本學位論文。本人完全意識到本聲明的法律后果由本人承擔。除了文中特別加以標注引用的內(nèi)容外,本論文不包含任何其他個人或集體已經(jīng)發(fā)表或撰寫的成果作品。不保密 □。本人授權省級優(yōu)秀學士學位論文評選機構將本學位論文的全部或部分內(nèi)容編入有關數(shù)據(jù)庫進行檢索,可以采用影印、縮印或掃描等復制手段保存和匯編本學位論文。本人完全意識到本聲明的法律后果由本人承擔。分類號 U D C 編號 碩士學位論文 變式教學在高中不等式教學中的應用研究 華中師范大學學位論文原創(chuàng)性聲明本人鄭重聲明:所呈交的學位論文是本人在導師指導下獨立進行研究工作所取得的研究成果。除了文中特別加以標注引用的內(nèi)容外,本論文不包含任何其他個人或集體已經(jīng)發(fā)表或撰寫的成果作品。學位論文作者簽名: 日期: 年 月 日學位論文版權使用授權書本學位論文作者完全了解學校有關保障、使用學位論文的規(guī)定,同意學校保留并向有關學位論文管理部門或機構送交論文的復印件和電子版,允許論文被查閱和借閱。本學位論文屬于保密 □ ,在_____年解密后適用本授權書。(請在以上相應方框內(nèi)打“√”)學位論文作者簽名: 日期: 年 月 日導師簽名: 日期: 年 月 日 學位論文原創(chuàng)性聲明本人鄭重聲明:所呈交的論文是本人在導師的指導下獨立進行研究所取得的研究成果。對本文的研究做出重要貢獻的個人和集體,均已在文中以明確方式標明。作者簽名: 日期: 年 月 日學位論文版權使用授權書本學位論文作者完全了解學校有關保留、使用學位論文的規(guī)定,同意學校保留并向國家有關部門或機構送交論文的復印件和電子版,允許論文被查閱和借閱。涉密論文按學校規(guī)定處理。因此變式教學便是通過不同角度、不同側面、不同情形、不同背景的變式手段使學生有效地加深認識和理解數(shù)學對象的本質特征的活動過程。本文首先介紹研究變式教學的實際意義,總結前人對變式和變式教學的研究。接著,在初中數(shù)學教學實踐的基礎上,結合教學案例進行分析說明,通過實驗研究,從學生的體會和學業(yè)成績兩個方面對初中數(shù)學變式教學的實踐效果進行分析和評價,并指出研究中運用數(shù)學變式教學的存在問題。不等式是高中數(shù)學的重要內(nèi)容,是數(shù)學基礎理論的一個重要組成部分。高中數(shù)學中許多重要的數(shù)學思想方法如分類討論、整體換元、數(shù)形結合、轉化化歸思想,都可以借助于不等式教學來實現(xiàn)。 隨著新課程改革的逐步深入,如何在課堂中利用變式教學來提高數(shù)學教學的效率已經(jīng)成為大家關注的焦點。關鍵詞:變式; 變式教學;不等式;概念變式; AbstractCurrent variable type teaching is an important characteristic of middle school mathematics teaching in our country, the socalled variable type, is the problem from various change materials provided or presented in the form of the things the essential characteristics, whereas the essential characteristics of things stay the same way of change. Therefore variable type teaching is through different angles, different sides and different situations, different background variable type means to make the students effectively deepen understanding and the understanding of the essential characteristics of mathematical object activity process. Variable type teaching to help students understand the meaning of knowledge, familiar with mathematical method, clear link between knowledge, summarizes the mathematical laws, improve math ability has positive significance. This paper first introduces the practical significance of the research type teaching, summarizing predecessors to change type and research type teaching. Secondly, on the basis of existing research, the article expounds the meaning of change type and type teaching, systematically summarizes the variant teaching: the theoretical basis of the meaningful learning theory, madden variation theory, the theory of the zone of proximal development, scaffolding theory. Then, in the junior middle school mathematics teaching practice, on the basis of bining the teaching case analysis shows that, through the experimental research, from two aspects of students39。 abstract, concrete, inverse, deposition, bination, analogy and other mathematical thinking has a certain function, thus to put forward the outlook for the further research type teaching.Inequality is an important content of high school mathematics, is an important part of the basic theories of mathematics. Inequality in the high school mathematics is the foundation, and the properties of its property settlement method which has been widely applied in other areas of knowledge, such as function, monotonicity, the values, the plural of domain and so on. High school mathematics discussed in many important mathematical thinking methods such as classification, overall in yuan, several form bining, the transformation of thinking, can be implemented by using inequality , never study math equation of variable type teaching has important practical significance.With the new curriculum reform gradually thorough, how to use variant in classroom teaching to improve the efficiency of the mathematics teaching has bee the focus of attention. In this paper, on the basis of the relevant literature review bined with teaching practice and their own experience, on the basis of the inequality of teaching research, through the classroom experiment and questionnaire survey of related conclusions.Keywords: variable type teaching inequality concept of variant。當時有許多中國中小學生參加的有關數(shù)學成績的國際比較研究,一直重復著一個矛盾的結果。一方面,許多研究表明,中國學生不僅在數(shù)學成績國際比較中,而且在各種奧賽表現(xiàn)都要比西方學生好。中國教師經(jīng)常用“
