Produção de significados sobre matemática nos cartuns

Esta pesquisa tem por objetivo analisar e problematizar os significados produzidos sobre Matemática nos cartuns. Não se trata de propor uma utilização pedagógica, mas de fazer uma tentativa de mostrar o que eles ensinam com os saberes que inventam sobre Matemática. Para isso, analiso as representações de Matemática presentes nos discursos dos cartuns, entendendo-os como artefatos da cultura que produzem narrativas que põem em circulação significados na arena de uma política cultural. Como referencial teórico, utilizo-me do campo dos Estudos Culturais em suas versões contemporâneas inspiradas no pós-modernismo e no pós-estruturalismo. Autores e autoras como Stuart Hall, Michel Foucault, Valerie Walkerdine, Kathryn Woodward, Alfredo Veiga-Neto, Guacira Lopes Louro, Marisa Vorraber Costa, Rosa Hessel Silveira, Tomaz Tadeu da Silva, entre outros/as, a partir de suas produções nesse campo, contribuem para as análises de cartuns que circulam em nosso meio nos jornais, revistas, gibis e sites da Internet. Os significados sobre Matemática produzidos nos cartuns foram agrupados, para fins de análise, em três focos: a metanarrativa da onisciência, onde abordo aqueles significados que conferem ao conhecimento matemático um caráter diabólico, complexo, inacessível, transcendental, que apresentam a crença de que o mundo é matematizado segundo leis divinas; o gênero da Matemática, relativo àqueles que opondo as mulheres aos homens, colocando estes num pólo privilegiado de raciocínio e aquelas num pólo oposto, deficitário, generificam a área da Matemática como sendo masculina, assim como se generifica o trabalho docente como feminino; e o terror das provas, apresentando aqueles que mostram os momentos de avaliação nas aulas de Matemática sempre povoados por sentimentos de desespero, pavor e sofrimento.

Eram realmente pitagórico(a)s os homens e mulheres catalogado(a)s por Jâmblico em sua obra Vida de Pitágoras?

Pythagoras was one of the most important pre-Socratic thinkers, and the movement he founded, Pythagoreanism, influenced a whole thought later in religion and science. Iamblichus, an important Neoplatonic and Neopythagorean philosopher of the third century AD, produced one of the most important biographies of Pythagoras in his work Life of Pythagoras. In it he portrays the life of Pythagoras and provides information on Pythagoreanism, such as the Pythagorean religious community which resembled the cult of mysteries; the Pythagorean involvement in political affairs and in the government in southern Italy, the use of music by the Pythagoreans (means of purification of healing, use of theoretical study), the Pythagorean ethic (Pythagorean friendship and loyalty, temperance, self-control, inner balance); justice; and the attack on the Pythagoreans. Also in this biography, Iamblichus, almost seven hundred years after the termination of the Pythagorean School, established a catalog list with the names of two hundred and eighteen men and sixteen women, supposedly Pythagoreans of different nationalities. Based on this biography, a question was raised: to what extent and in what ways, can the Pythagoreans quoted by Iamblichus really be classified as Pythagoreans? We will take as guiding elements to search for answers to our central problem the following general objectives: to identify, whenever possible, which of the men and women listed in the Iamblichus catalog may be deemed Pythagorean and specific; (a) to describe the mystery religions; (b) to reflect on the similarities between the cult of mysteries and the Pythagorean School; (c) to develop criteria to define what is being a Pythagorean; (d) to define a Pythagorean; (e) to identify, if possible, through names, places of birth, life, thoughts, work, lifestyle, generation, etc.., each of the men and women listed by Iamblichus; (f) to highlight who, in the catalog, could really be considered Pythagorean, or adjusting to one or more criteria established in c, or also to the provisions of item d. To realize these goals, we conducted a literature review based on ancient sources that discuss the Pythagoreanism, especially Iamblichus (1986), Plato (2000), Aristotle (2009), as well as modern scholars of the Pythagorean movement, Cameron (1938), Burnet (1955), Burkert (1972), Barnes (1997), Gorman (n.d.), Guthrie (1988), Khan (1999), Mattéi (2000), Kirk, Raven and Shofield (2005), Fossa and Gorman (n.d.) (2010). The results of our survey show that, despite little or no availability of information on the names of alleged Pythagoreans listed by Iamblichus, if we apply the criteria and the definition set by us of what comes to be a Pythagorean to some names for which we have evidence, it is possible to assume that Iamblichus produced a list which included some Pythagoreans

Práticas dialógicas e cidadania no ensino de ciências: uma experiência educativa com mulheres e homens do campo em Curupaiti - Viseu/PA

O presente trabalho, intitulado Práticas Dialógicas e Cidadania no ensino de ciências: uma experiência educativa com mulheres e homens do campo em Curupaiti – Viseu,/PA, foi desenvolvido com uma turma de 2ª etapa de Educação de Jovens e Adultos – mulheres e homens do campo. Tem como objeto de estudo práticas pedagógicas de Educação em Ciências que consideram como ponto de partida para a construção de conhecimentos as realidades dos educandos, visando uma educação dialógica e interdisciplinar em prol de sua formação cidadã. Objetiva investigar se tais práticas pedagógicas contribuem para uma educação dialógica e interdisciplinar em prol de sua formação cidadã. A questão de pesquisa é expressa do seguinte modo: Em que termos práticas pedagógicas que consideram as realidades de alunos do campo na modalidade de Educação de Jovens e Adultos contribuem para uma educação dialógica e interdisciplinar na educação em ciências, como mediação para a formação para a cidadania? Trata-se de uma pesquisa qualitativa na abordagem pesquisa-ação, de natureza narrativa. As ações pedagógicas desenvolvidas foram relacionadas à alimentação humana, ao plantio de feijão como atividade econômica e a projetos de agricultura familiar na perspectiva da agroecologia. Os instrumentos de pesquisa utilizados foram diários e entrevistas não estruturadas. São analisadas três práticas pedagógicas desenvolvidas com a turma, constituindo o que denomino de teias dialógicas, o que, neste estudo, traduz a idéia de que tais episódios estão ligados a momentos anteriores à sua ocorrência, propriamente dita, tais como o planejamento e também a situações posteriores, sempre numa perspectiva de interação. A primeira teia é denominada Alimentação humana: uma alternativa na perspectiva popular; a segunda, Dialogando às sombras do feijoal e a última, Agricultura Familiar e os desafios da agroecologia. Considero nas análises, como pontos de destaque, as relações de diálogos estabelecidas entre os sujeitos envolvidos, entre as disciplinas escolares e entre diferentes tipos de conhecimentos. A concepção de diálogo adotada neste trabalho diz respeito a uma compreensão interativa que admite que num diálogo há interação e nunca hierarquização e supremacia de um dos atores envolvidos. As reflexões construídas são indiciárias de que ações pedagógicas construídas com os sujeitos do processo educativo, tendo como ponto de partida a realidade em que estão inseridos, convergem para uma educação dialógica e interdisciplinar coerente com o propósito de construção de cidadania, cuja percepção de vida e sociedade compreende uma teia que não pode ser entendida sem seus fios e suas múltiplas relações de complexidade.

A presença das mulheres nas ciências exatas

Most well-known and studied names in schoolbooks are men's. It gives one the idea that the world of numbers does not belong to female individuals. In order to verify that this thought is a misconception, a research is carried out about women who, despite all prejudice, have faced many adversities, leaving us many contributions on exact sciences and being relevant until the present date. Nowadays, there is not as much sexual discrimination. Women’s under-representation in exact sciences is due to other motives, such as issues of choice and the option of part-time jobs for professional/familiar balance. Maybe because of this, women have little acknowledgment, as it can be seen in Nobel Prize, where of its 851 awards, only 44 were for women. They are present at different degrees of education, such as licentiate graduation, bachelor’s or master’s, but still outnumbered. The number of female graduates was higher than male’s, according to collected data from Mathematics licentiate graduation Department from 2000 until 2012 in UNESP, Guaratinguetá campus

Modelagem matemática e simulação numérica do resfriamento rápido de morango com ar forçado

This work approaches the forced air cooling of strawberry by numerical simulation. The mathematical model that was used describes the process of heat transfer, based on the Fourier's law, in spherical coordinates and simplified to describe the one-dimensional process. For the resolution of the equation expressed for the mathematical model, an algorithm was developed based on the explicit scheme of the numerical method of the finite differences and implemented in the scientific computation program MATLAB 6.1. The validation of the mathematical model was made by the comparison between theoretical and experimental data, where strawberries had been cooled with forced air. The results showed to be possible the determination of the convective heat transfer coefficient by fitting the numerical and experimental data. The methodology of the numerical simulations was showed like a promising tool in the support of the decision to use or to develop equipment in the area of cooling process with forced air of spherical fruits.

Projeto de um cortador de base para colhedora de cana-de-açúcar utilizando otimização matemática

A base-cutter represented for a mechanism of four bars, was developed using the Autocad program. The normal force of reaction of the profile in the contact point was determined through the dynamic analysis. The equations of dynamic balance were based on the laws of Newton-Euler. The linkage was subject to an optimization technique that considered the peak value of soil reaction force as the objective function to be minimized while the link lengths and the spring constant varied through a specified range. The Algorithm of Sequential Quadratic Programming-SQP was implemented of the program computational Matlab. Results were very encouraging; the maximum value of the normal reaction force was reduced from 4,250.33 to 237.13 N, making the floating process much less disturbing to the soil and the sugarcane rate. Later, others variables had been incorporated the mechanism optimized and new otimization process was implemented .

Mulheres indigenas: poder e tradição

This study contemplates reports and reflections about gender and the interfaces with work, power and woman's political participation within the Bororo indigenous communities in Mato Grosso, Guarani/Kaiowá and Kadiwéu ones, in Mato Grosso do Sul. In the study with the Bororo community, the woman valorization occurred because she represents the guardian of the culture and of the traditional knowledge, and at the same time, she is an important speaker for the Bororo and the non indigenous society. In the case of Guarani/Kaiowá community, the most important facts are, on one side, the departure of the men and their wish to become city men, and on the other, the women who wish or need to keep the Guarani identity and live in the reserve. In the Kadiwéu community, the most important fact is the women political power and a role division between men and women, without the attribution of more value to one role or the other.

Influência da atividade física na qualidade de vida e auto-imagem de mulheres incontinentes

Our aim was to verify the influence of a physical activities proposal in the quality of life and self image of incontinent women. This study was comparative and exploratory and was developed in 16 weeks. Thirty-seven women with and without urinary incontinence (IU) participated in the study. After the study, significant improvement in general health perception (p < 0.001), UI impact (p = 0.035), physical limitations (p = 0.015), personal relations, (p = 0.048), sleep and disposition (p = 0.012) and concerned with the gravity measurements (p = 0.011) was observed. Concerning self image, alterations in appearance were not observed; however, concerning body satisfaction, the women felt less satisfied with their bodies (p = 0.007). There was a reduction in the number of regions where they felt pain (p = 0.0003) and that they did not like (p = 0.0017). In conclusion, the Physical Education professionals using a systematized and integrated physical activities program can lead the women with IU to significant improvement in the perception of their quality of life and health concerning their self image with improvement of the IU symptoms and reduction of frequency and amount of urinary loss.

Respostas cardiopulmonares agudas de mulheres no treinamento de força

OBJETIVE: Investigate the cardiopulmonary responses of one strength training session in young women. METHOD: Twenty-three women aged between 18 and 29 years participated in this study. All the volunteers were submitted to the following tests: cardiopulmonary and one-repetition maximum (1-RM). The strength training protocol had emphasis on muscular hypertrophy, three sets from eight to twelve repetitions under 70% of 1-RM, with a one minute thirty-second break between sets. During the training session, the cardiopulmonary variables were measured with a metabolic gas analyzer and a telemetry module. RESULTS: The results of the oxygen consumption in the training session were from 8.43 + 1.76 ml/kg/min and of the heart rate of 108.08 + 15.26 bpm. The results of the oxygen consumption and of the heart rate in the training were lower (p < 0.01) than in the ventilatory threshold and of the oxygen consumption and the heart rate reserves. CONCLUSION: The obtained data show that the present protocol of strength training provided low overload to the cardiopulmonary system of young women.

Sociedade, cultura, matemática e seu ensino

One of the effects of the globalized world is a strong tendency to eliminate differences, promoting a planetary culture. Education systems are particularly affected, undergoing strong pressure from international studies and evaluations, inevitably comparative, and sadly competitive. As a result, one observes the gradual elimination of cultural components in the definition of education systems. The constitution of new social imaginaries becomes clear; imaginaries empty of historical, geographical and temporal referents, characterized by a strong presence of the culture of the image. The criteria of classification establish an inappropriate reference that has as its consequence the definition of practices and even of education systems. On the other hand, resistance mechanisms, often unconscious, are activated seeking to safeguard and recover the identifying features of a culture, such as its traditions, cuisine, languages, artistic manifestations in general, and, in doing so, to contribute to cultural diversity, an essential factor to encourage creativity. In this article, the sociocultural basis of mathematics and of its teaching are examined, and also the consequences of globalization and its effects on multicultural education. The concept of culture is discussed, as well as issues related to culture dynamics, resulting in the proposition of a theory of transdisciplinar and transcultural knowledge. Upon such basis the Ethnomathematics Program is presented. A critique is also made of the curriculum presently used, which is in its conception and detailing, obsolete, uninteresting and of little use. A different concept of curriculum is proposed, based on the communicative (literacy), analytical (matheracy), and material (technoracy) instruments.

História, filosofia e sociologia da educação matemática na formação do professor: um programa de pesquisa

We present and discuss in this article some features of a research program whose central object of investigation is the way in which the recent fields of history, philosophy, and sociology of mathematical education could take part in a critical and qualified manner in the initial and continuing training of teachers in this area. For that, we endorse the viewpoint that the courses for mathematics teacher education should be based on a conception of specificity through which a new pedagogical project could be established. In such project those new fields of investigation would participate, in an organic and clarifying way, in the constitution of multidimensional problematizations of school practices, in which mathematics would be involved, and that would be guided by academic investigations about the issues that currently challenge teachers in the critical work of incorporation, resignification, production, and transmission of mathematical culture in the context of the school institution.
