Growth in Students' Conceptions of Mathematical Induction

Gruver, John David 06 May 2010 (has links) (PDF)
While proof and reasoning lie at the core of mathematical practice, how students learn to reason formally and build convincing proofs continues to invite reflection and discussion. To add to this discussion I investigated how three students grew in their conceptions of mathematical induction. While each of the students in the study had different experiences and grew in different ways, the grounded axes (triggering events, personal questions about mathematics, and personal questions about a particular solution) highlighted patterns in the narratives and from these patterns a theoretical perspective emerged. Reflection, both on mathematics in general and about specific problems, was central to students' growth. The personal reflections of students and triggering events influenced each other in the following way. The questions students wondered about impacted which trigger stimulated growth, while triggers caused students to rethink assumptions and reflect on mathematics or specific problems. The reflections that allowed triggers to stimulate growth along with the reflections that were results of triggering events constitute an "investigative orientation." Each narrative reflects a different investigative orientation motivated by different personal needs. These investigative orientations affected what type of knowledge was constructed.

It initially some considerations are made about the expression "inductive reasoning" whose it meaning, as appropriately must be explained in the text, that differs from that of "mathematical induction". We prove the proposition that guarantees the use of the method based on its foundation, namely the axiom of mathematical induction (one of the postulates that characterize the natural numbers). It exhibited some examples of its use of Algebra and the Theory of Numbers. And then, some applications of the method of mathematical induction to the problems of Geometry are explored to obtain a geometric measure in terms of another(s), either for the demonstration of a proposition that insinuates itself true, or for the stages of construction of a figure given / Este trabalho trata do Método de Indução Matemática, em especial, de seu uso com vistas à solução de problemas geométricos. Inicialmente, são feitas algumas considerações acerca da expressão "raciocínio indutivo", cujo sentido, conforme apropriadamente explicado no texto, difere do de "indução matemática". É provada a proposição que garante o uso do método com base em seu fundamento, a saber, o axioma de indução matemática (um dos postulados que caracterizam os números naturais) e exibidos alguns exemplos de sua utilização em Álgebra e Teoria dos Números. Em seguida, são exploradas algumas aplicações do método de indução matemática à problemas de Geometria, seja para a obtenção de uma medida geométrica em termos de outra(s), para a demonstração de uma proposição que se insinua verdadeira, ou para a exibição das etapas de construção de uma dada figura.

Teoria matemática implícita na geometria fractal: construindo fractais com a ferramenta computacional Asymptote

Jerrimar Moraes de Araújo 03 December 2015 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O presente trabalho consiste em um relato sobre a origem da Geometria Fractal, tendo em destaque a figura de Benoît Mandelbrot, identificado como pioneiro nesta área, cujo fractal leva seu nome. Mostra os fractais pioneiros, assim como a construção destes através da ferramenta computacional "Asymptote". É necessário dizer que, a partir da construção destes, percebe-se, com facilidade um intenso uso de conteúdos presentes no currículo escolar do ensino básico, como por exemplo o cálculo de perímetro e de áreas de figuras planas, potenciação, problemas de contagens, entre outros, os quais podem ser abordados com o intuito de introduzir tal conteúdo ou mesmo aprofundá-lo. Por fim, faremos uso de Indução Matemática para demonstrar algumas destas fórmulas encontradas. / This work consists the historic report of the origin of Fractal Geometry, and highlighted the figure of Benoît Mandelbrot, identified as pioneer in this area, whose fractal bears his name. Shows the pioneers fractals, as well as the construction of these using the computational tool "Asymptote". It must be said that, from the construction of these, it is noted, easily a intense use of contents present in the curriculum of basic education, such as the calculation of perimeter and area of plane figures, potentiation, in counts problems, among others, they can be addressed in order to start the study of such content or to same deepen it. Finally, we will make use of Mathematical Induction to demonstrate some of the formulas found.

The Cauchy-Schwarz inequality : Proofs and applications in various spaces / Cauchy-Schwarz olikhet : Bevis och tillämpningar i olika rum

Wigren, Thomas January 2015 (has links)
We give some background information about the Cauchy-Schwarz inequality including its history. We then continue by providing a number of proofs for the inequality in its classical form using various proof techniques, including proofs without words. Next we build up the theory of inner product spaces from metric and normed spaces and show applications of the Cauchy-Schwarz inequality in each content, including the triangle inequality, Minkowski's inequality and Hölder's inequality. In the final part we present a few problems with solutions, some proved by the author and some by others.

UMA PROPOSTA DE ABORDAGEM AO PROBLEMA DE FLÁVIO JOSEFO APLICADA AO ENSINO MÉDIO / AN APPROACH PROPOSAL OF FLAVIO JOSE`S PROBLEM APPLIED TO HIGH SCHOOL

Souza, Márcia Erondina Dias de 15 April 2013 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In this paper, we presents a didactic sequence of activities designed for a group of students of high school, their age were about 15 and 18 years old, with the main objective to study the problem proposed by the mathematician Flávio Josefo, in mid-year 64. The legend tells that a group of rebels, including Flávio Josefo, was trapped in a cave by the enemy army. Preferring the suicide to capture, the rebels decided to form a circle and, counting over this, to kill each third person of the rest of the group. Josefo was contrary of this suicide pact therefore, together with a friend, calculated very quickly the appropriated positions that both should take in this circle in order to get out of this terrible situation. To understand this solution, we propose, at the first moment, a review about the numerical sequences, including the special cases of arithmetic and geometric. Then, we introduce some notions about the de recurrence relations and the Principle of Mathematical Induction, allowing a generalization of concepts and results already known intuitively by the student group. / Neste trabalho, apresentamos uma sequência didática de atividades elaboradas para um grupo de alunos do ensino médio, na faixa etária de 15 a 18 anos, tendo como principal objetivo estudar o problema proposto pelo matemático Flávio Josefo, nos meados do ano 64. Conta a lenda que um grupo de rebeldes, dentre eles Flávio Josefo, foi encurralado numa caverna pelo exército inimigo. Preferindo o suicídio à captura, os rebeldes decidiram formar um círculo e, contando ao longo deste, matar cada terceira pessoa restante do grupo. Josefo era contrário a este pacto suicida e, por isso, juntamente com um amigo, calculou muito rapidamente as posições adequadas que ambos deveriam tomar nesse círculo de modo a saírem ilesos desta terrível situação. Para o entendimento desta solução propomos, inicialmente, uma revisão sobre sequências numéricas, incluindo os casos especiais de progressão aritmética e geométrica. Em seguida, introduzimos algumas noções a respeito de relações de recorrência e do Princípio da Indução Matemática, permitindo uma generalização dos conceitos e resultados já conhecidos intuitivamente pelo grupo de alunos.
