隨機應答取樣之研究

陳綉真, Chen, Zhen Unknown Date (has links)
在隨機應答的技巧之中,自華納(Warner,1965) 提出華納模式後,即有多位學者以華納的觀點為籃圖,展開一系列的縱橫發展,並插枝分葉出各式技巧來(Chandhuri & Makerjee,1988)。 本文在第一、二章內,將分別介紹其中最典型的兩種方式:華納模式(Warner Model)與不相關問題模式(Unrelated-Question Model)。在第一章中並圖示固定的參數設計p 之下,比較華納模式的隨機應答方式與一般的直接應答方式效率之優劣,隨受訪者的誠實度變化之情形。在第二章中,除介紹不相關問題模式的技巧與方法外,也圖示比較華納模式與不相關問題模式取樣結果的估計值有效性之優劣。在第三章中,則闡述保護受訪者隱私的立場與獲得有效估計的目的如何互相衝突、矛盾,而定下參數設計的準則,以求取二者之間的平衡。最後一章則因Greenberg(1977) 所定義的冒險函數未能由所給的數學式完全描述,故在此章提出一些較合理的修正。

迪菲五邊形 / Diffy Pentagon

黃信弼 Unknown Date (has links)
在迪菲方塊中,我們將正方形的四個頂點皆填入數值,再利用相鄰兩頂點相減,再取絕對值的方式觀察其數列行為,發現四個頂點的數字最後皆會收斂至0。在本文中,我們將之推廣至五邊形,我們稱它為迪菲五邊形。我們套用同樣的運算模式後,發現亦有特殊的收斂行為。 / In Diffy box, we write down numbers on the four vertices of square, and then on the midpoint of each side write the difference between the two numbers at its endpoints. It is known that the numbers on the four vertices of a square will converge to zero finally. In this article, we use the same operations as Diffy box to discuss pentagons which we call" Diffy pentagon ". We find it will converge, too.

台灣與中國國中數學教科書之內容分析研究 / The content analysis of junior high mathematics textbooks in Taiwan and China

謝佩珍 Unknown Date (has links)
迎接21世紀的來臨與世界各國之教改脈動,自1997年起,台灣政府致力教育改革,以期提升國民素質及國家競爭力。因此,教育部依據行政院核定之「教育改革行動方案」,進行國民教育階段課程與教學改革。隨著「九年一貫課程綱要」的公佈,台灣正式開啟一連串的教育革新。而對岸的中國,也於2001年啟動第八次基礎教育課程改革。兩國教育改革的內容皆涉及到課程目標、課程內容、課堂教學、學生學習等各層面,因此教科書、教材教法皆產生了巨大的變化。現有關於兩岸教育相關研究相當多,但兩岸課程的比較研究多停留在國小階段;且針對教科書的研究多半是以教科書的制度、審定為主,幾乎未有針對兩岸國中階段教科書的內容比較。 本研究先簡略介紹兩國教育背景並進行九年義務教育課程目標的分析,再對台灣康軒版、中國人教版國中數學課本、習作、教師手冊做出比較,得出結果如下: 一、在課程目標方面,兩者都強調數學與生活、其他學科的連結,也強調學生創新能力的培養;不同的是,中國人教版較強調數學各主題中的深耕,台灣康軒版則偏向各主題間的橫向連結;而中國人教版也較注重傳統的數學運算能力,台灣康軒版則較重視數學在生活中的運用。 二、在數學課本課程內容中,台灣課程偏向主題集中學習,而中國課程則偏向主題分散學習,每一學年課程都有代數、幾何、資料統計與機率。除此之外,中國人教版不論是代數或幾何,習題數約是台灣康軒版的三倍,但台灣康軒版在代數部份,課程較為流暢;中國人教版在幾何部份題目題材較多元。 三、在課本編輯方面,兩者架構都相當類似,皆具備章前圖、多元正文欄目、重點整理、補充知識等,但台灣康軒版部分章節,列中字數過多,且沒有數學名詞的中英文對照 四、在習作排版方面,中國人教版像是一本濃縮參考書,但台灣康軒版全版彩色,計算空間大,版面整齊,但中國人教版排版密集,閱讀上較為辛苦。 基於以上結論,針對台灣教科書提出以下建議: 1.幾何部份可以增加動手操作的機會,如折紙。 2.可以增加課本中的習題數,讓學生有多一點練習的機會。 3.增加數學史課程,適當說明前人在解決日常問題中的數學智慧。 4.增加統整課程的題型,題目的題材可以結合理化、美術等,增加多 元類型,提供學生思考的空間。 / To welcome the 21st century and catch up with other countries’ educational efforts, the government in Taiwan has engaged itself to educational reform since 1997. The purpose is to enhance the quality of its people and the ability to compete with other countries. Hence the Ministry of Education has tried to reform the compulsory education curriculum and teaching according to the “Action Proposal for Educational Reform,” authorized by the Executive Yuan. After the publication of “Grade 1-9 Curriculum Guidelines,” Taiwan has formally initiated a series of educational reforms. Similarly, Mainland China has started its eighth reform on Basic Education Curriculum. The reforms in both countries include the curriculum target, the curriculum content, classroom teaching, and students’ learning. They unavoidably exert a huge impact on the textbooks and teaching materials. Related researches on the education in both countries abound. However, the comparison of curriculum in both countries basically focuses on elementary school curriculum. Also, most researches on textbooks focus on the system or authorization. Seldom do we find research that focuses on the textbooks in junior high school. This research will first briefly introduce the education background in both countries and then analyze the target of compulsory education curriculum. The Kang Xuan version of Taiwan and the People’s Education version of China are taken as examples. We get the following conclusion after comparing their mathematics textbooks, workbooks, and teacher’s manuals. First, in terms of curriculum target, both versions emphasize the connection between mathmatics and life or other subjects. Both aim to cultivate the students’ creativity, too. Differently, People’s Education version goes deeper within one single topic, while Kang Xuan version focuses on the horizontal connection between different topics. People’s Education version puts more emphasis on the traditional arithmetic, while Kang Xuan version puts more emphasis on the application of math in everyday life. Second, according to the content of these two versions, when a new topic is introduced, the curriculum in Taiwan prefers concentrative learning, while the other version favors learning at different phases. Take People’s Education for example, every school year students have to learn algebra, geometry, data statics, and probability. Besides, in terms of algebra or geometry, People’s Education version provides exercises three times than Kang Xuan version does. Kang Xuan version, however, has a smoother curriculum design in terms of algebra. As for geometry, People’s Education version offers more different types of exercises. Third, speaking of the editing, both versions have similar curriculum structure. We can find in both versions pictures before each chapter, multiple columns presenting the main idea, arrangements of important points, and appended knowledge. However, some chapters of Kang Xuan version have too many words in one line, and it lacks Chinese-English terminology of math. Fourth, in terms of the workbooks, People’s Education version looks like a condensed reference book, while Kang Xuan version is bigger and more colorful. Kang Xuan version provides space for calculation and has neater arrangement, while People’s Education version is too wordy and takes more time to read the questions. Based on the conclusion above, this study offers some suggestions for future compilation of the Taiwanese mathematics textbooks: 1. For geometry, a good mathematics textbook should provide students with more opportunities to have hands on experiences, for example, by way of paper folding. 2. There should be more exercises in the textbook, hence giving the students more chances to practice. 3. History of mathmatics can be added. Students may have a better idea how ancient people used their wisdom to solve everyday mathmatics problems. 4. Exercises related to integrated curriculum should be added, too. Different subjects like science, art, etc…, can be combined together to provide multiple elements and a wider space for students’ ideas.

SOME PERMUTATION BINOMIALS AND WEAK CARLITZ'S CONJECTURE

黃培琨, Huang, Pei-Kun Unknown Date (has links)
壹、引言 近年來,訊號傳送的途徑,已擺脫了傳統上著重管線傳送的優勢;有愈來愈多的訊號 彌漫在廣闊的空間裡,而這種無線式的傳送所需面臨的問題是:不具有排它性,任何 有接收器材的非原始接收者都可以截聽到訊息,由於因應而生的保密技術格外受矚目 ,密碼學(CRYPTOGRAPHY)便是滿足此需要的學問。本論文所探討的排列多項式(PE RMUTATION POLYNOMIAL)是密碼學中重要的工具之一。 貳、論文主體 所謂排列多項式,即是佈於代數體上的多項式,把此多項式當成函數而作用於代數體 (FIELD )上,如果此函數具有一對一的性質,則是排列多項式。即 f(x)=a。+ a1 x1 + ....anxn ≡ Fq〔X〕且 f(a)╪f(b),a,b≡Fq,a╪b. 在論文中,介紹先進學者對排列多項式的認識。如:LAGRANGE'S INTERPOLATION是利 用函數值來描繪多項式,著名的學者CARLITZ ,利用特殊多項式來合成出排列多項式 ,論文中有更進一步的合成法提出,而HERMITE 跟DICKSON 學者則提出Ft函數其冪次 的變化情形,來判別排列多項式之是否,是最通俗的判別理論。 此外,由吾人所蒐集的資料中發現,在祗有兩項的多項式中,被發現到其它更簡捷快 速的判別方法,故二項式的多項式的探討是本論文的第一主題,對於 k j X+bx ≡Fq〔X〕, 給予固定類型的q,k,j情形下,祗須檢定b是否具特 殊性質就可決定是否為排列多項式,這是一種方法。另有學者並不固定q,k,j, 反而從q,k,j數字下手,找尋出某種關連性,其結果使得係數b,只有當b=0 ,時才有機會是排列多項式,乘下單項式的判別過程,就很容易了。另外還有一種方 法也是找尋q,k,j間的關係,不過其結果在找出:多項式為非排列多項式,是比 較特別的地方。上述三方法,本論文網羅大部份有關論文,綜合各家之長,並適當給 予一同於原作者的新觀點證明方法。 至於本論文第二主題是著名的CARLITZ'S CONJECTURE此預測敘述:對於任何具有最高 冪次是偶數的多項式,必定存在一個自然數k,使得給定的代數體,其元素個數只要 超過k,則此多項式必定不是排列多項式。此預測當degree n=10,12,14, and 2m 時 已被證實為真。本論文僅就n=2m,做系統地探討及重新證明。 參、結語 本論文所論的兩主題,對於佈於代數體上的多項式是否為排列多項式,在判別的過程 上應有相當的助益才是。

以動態評量回饋系統提升國中數學學習成效 / The study of using of Dynamic Asessment Feedback system to enhance the mathematics achievement of junior high school

鄭佳虹, Cheng, Chia-Hung Unknown Date (has links)
本研究主要目的在瞭解透過動態評量回饋系統輔助教學對提升國中數學學習成效及數學學習態度的影響。本研究針對新北市某國中八年級兩班學生共38人,每週進行五節,總計為六週之數學教學實驗。本研究採準實驗研究設計,自變項為教學模式,在實驗組以動態評量回饋系統融入學習之數學教學課程而在對照組使用一般傳統教學方法進行數學評量及回饋課程。依變項為「數學學習成效測驗」、「數學學習態度量表」,共變項為八上三次段考平均。以單因子共變數分析與二因子重複量數混合設計變異數分析進行統計分析,研究結果如下: 一、在數學科學習成效方面:以動態評量回饋系統輔助數學教學,能提升數學科學習成效。 二、在數學學習態度方面:在數學學習態度分向度之「外在動機」向度上,實驗組與對照組有顯著差異,證實以動態評量回饋系統輔助數學教學,能提升數學學習態度之外在動機。在數學學習態度整體面向並未有顯著差異,證實以動態評量回饋系統輔助教學並未能提升數學整體學習態度。 三、學生對動態評量回饋系統輔助教學的回饋: 1、學生普遍具有正向、積極的反應。 2、學生願意多花時間來加強數學的學習。 綜上所述,本研究針對結果提出具體建議,以提供教學設計、數學教學及未來相關研究之參考。 / The purpose of this study was to investigate junior high school students’ mathematics learning achievement by using a Dynamic Assessment and Feedback (DAF) system. The overall investigation process is designed as a quasi-experiment, where two classes of eighth-grade junior high school students in New Taipei County were randomly assigned to either the experimental(n=18) or the control groups(n=20). It took totally six weeks, and there were five classes per week to perform the instructional experiments. In the experiments, the independent variables were instructional strategies and the dependent variables were Mathematics Achievement Test and Mathematics Learning Attitude. The measurement instruments include Questionnaire for Mathematics Learning Attitude, Mathematics Achievement Test, and Questionnaire for Students’ Perception of Mathematics Instruction with DAF system. According to the students’ Mathematics Achievement Test, the statistical analysis was performed by one-way ANCOVA. By conducting t-test for the scores of the math learning attitude measurement, the analysis of math learning attitude was carried out by the two-way Mixed ANOVA. After analyzing the data, the findings of this study are summarized below: 1.Mathematics Achievement: The experimental group scored higher in the Mathematics achievement test than the control group did. 2.Mathematics Learning Attitude: No significant interaction between the teaching methods was found in attitude for learning Mathematics. A significant difference was found between the experimental group and the control group in their extrinsic motivation for Mathematics Learning Attitude. 3.The students’ feedback after the (DAF) system mode: I.Most students in the experimental group did enjoy the DAF system. II.Most students were willing to spend more time using the DAF system to practice Mathematics. Finally, based on these findings, this study proposes several suggestions for school administrators, teachers in junior high school math curriculum and future research are also discussed.
