A matemática no ciberespaço: um olhar fenomenológico para a expressão dos sujeitos

With the implementation of new technologies on the world stage of communication, Internet access has become increasingly numerous. Being sought by this means all kinds of information, from knowledge to entertainment. This paper intends to report the experience in two communities of the Internet, particularly in the social network Orkut, entitled I Hate Mathematics and I Love Mathematics, whose members are students, teachers and people who want to express how they feel about mathematics. The goal is to understand what took the members of these communities to hate or love Mathematics, clarifying the nature of the network Orkut and its contribution to mathematics education. For the analysis of data from field work, we use the phenomenological approach. The procedures followed by such approach allowed us to build four open categories: Research and Background, revealing that the research activities allow students to develop strategies, develop creativity and shows that what is learned in classroom is not just an accumulation of knowledge; Teacher's Role shows that it is necessary that the teacher understands the meaning of being a teacher and worry about being a student; Acquisition Technique, it is necessary that students be able to understand what is done and how it is done, and Sense of What is Done, to do is not directly linked to comprehend. The interpretation of these categories helped us understand the investigated giving us source to analyze how Information and Communication Technologies (ICT) can help the teacher understand the student's relationship with Mathematics

Matemática comercial e financeira com a utilização de recursos digitais: uma experiência no ensino médio

This work aimed to investigate the possible contributions of the use of digital resources in the teaching and learning process of Commercial and Financial Mathematics concepts to high school students. Its development has included a survey of some researches on the topic as well as an experimental study of a qualitative type, in which the Webquest was used as methodology. It uses the computer, more precisely the internet resources, to assist students in building up knowledge. Eight meetings were held, in the after-school period, with a group of students of the second year of high school at a state public school in the city of Guaratinguetá. Aiming to evaluate the knowledge that students had about the theme, it was applied a diagnosis at first glance for further analysis and development of activities and interventions according to the students’ answers. Once the research data was analyzed, it was noted that the students had little knowledge regarding the basic contents of Commercial and Financial Mathematics, in addition to presenting difficulties in handling some of the digital resources used in the meetings. Nonetheless, from the students’ works, it was seen significant advances in understanding and building up knowledge on concepts such as percentage, simple and compound interest, savings, and sales involving prompt payment or in arrears

Análise da estabilidade do movimento rotacional de satélites artificiais com quatérnions e sob a influência de torques externos

The aim of this work is to analyze the stability of the rotational motion’s artificial satellite using the Routh Hurwitz Algorithm (CRH) and the quaternions to describe the satellite’s attitude. This algorithm allows the investigation of the stability of the motion using the coefficients of the characteristic equation associated with the equation of the rotational motion in the linear form. The equations of the rotational motion are given by the four cinematic equations for the quaternion and the three equations of Euler for the spin velocity’s components. In the Euler equations are included the components of the gravity gradient torque (TGG) and the solar radiation torque (TRS). The TGG is generated by the difference of the Earth gravity force direction and intensity actuating on each satellite mass element and it depends on the mass distribution and the form of the satellite. The TRS is created by changing of the linear momentum, which happens due to the interactions of solar photons with the satellite surface. The equilibrium points are gotten by the equation of rotational motion and the CRH is applied in the linear form of these equations. Simulations are developed for small and medium satellites, but the gotten equilibrium points are not stable by CRH. However, when some of the eigenvalues of the characteristic equation are analyzed, it is found some equilibrium points which can be pointed out as stables for an interval of the time, due to small magnitude of the real part of these eigenvalue

Contribuições da leitura e escrita para a aprendizagem da matemática com textos de diferentes contextos

This work aims describe, through a phenomenological approach to qualitative research, which are the contributions of reading and writing of texts from different contexts for learning mathematics. For this purpose, we developed activities involving reading, writing and math in classes in the 6th grade of elementary school to a state school Guaratinguetá. These activities constituted the research data as part of the fieldwork. We analyzed the data following the procedures of this phenomenological research which they are described by Bicudo (1994, 2000, 2011), Fini (1994) and Machado (1994). We base our study on reading, writing and mathematics in Nacarato (2009), Lopes (2009), Smole (2000) and Fonseca (2005), among others. In the analysis, we seek to clarify how meaningful situations of different contexts, helping to develop skills in reading, writing and interpretation of the student, which in turn help the students at understanding mathematics. After the analysis of data, we named the two open categories: Difficulty of Expression and Communication Facilities. The interpretation of categories allows us to understand that there is, by individuals, a communicative intention that is expressed in the texts

Os saberes, os desafios e a utilização de jogos no ensino da matemática na EJA: um estudo

A matemática está presente nas mais diversas atividades do nosso cotidiano. O interesse em realizar o Trabalho de Conclusão de Curso no âmbito da Educação de Jovens e Adultos/EJA, surgiu a partir do meu ingresso no Programa Institucional de Bolsa de Iniciação à Docência - PIBID no início do ano de 2010. O PIBID vem sendo desenvolvido em vários campi da Unesp, somente nos cursos de licenciatura e tem como financiadora a CAPES/MEC. No curso de licenciatura Plena em Pedagogia, o Programa EJA/PIBID Rio Claro atua na escola Municipal Celeste Calil, localizada em um bairro periférico, que tem como público alvo pessoas de baixa renda, alfabetizadas ou não. O trabalho que a cada dia vem sendo construído com as educandas me despertou muito interesse, principalmente com relação ao ensino da matemática, uma vez que a mesma está presente nas diversas esferas do cotidiano. Podemos acompanhar (observar) que as alunas já trazem consigo uma experiência de vida muito grandiosa com relação à solução de questões pertinentes a matemática. Para auxiliar na aprendizagem, recursos matemáticos vêm sendo introduzidos nas aulas, entre eles jogos, onde as educandas podem reviver situações cotidianas que, à primeira vista, facilita o processo de aprendizagem e resolução de problemas. O presente trabalho tem como objetivos fazer um levantamento de jogos matemáticos que poderão ser utilizados nas aulas da EJA, e também analisar o caderno de registros matemáticos do PIBID, no ano de 2010. Quanto à metodologia, buscam-se elementos na pesquisa qualitativa, bem como análise bibliográfica de jogos que foram levantados e também análise documental do caderno de registros do PIBID 2010, construído conjuntamente, pelo grupo de educandas e bolsistaseducadores

A presença das TIC no curso de licenciatura em matemática da UNESP - campus Guaratinguetá

This research shows an investigation on teaching formation in regards to the TICs. Our interest in this subject is due to the fact that new generations of students who attend school require that the classes make use of technology in the classroom environment. By following the phenomenological orientation we have carried out a study which involved a field research at the College of Engineering in Guaratinguetá using the graduate as well as senior students of the Bachelor's Degree in Mathematics of this university. We have analyzed the data under the light of texts of the following authors: Filho (2007), Valente (1993), Miskulin (2006), Borba and Penteado (2001) among others in order to understand the teacher`s formation process to act using technologies in the classroom and its relevance. The data that has been analyzed was obtained in interviews which were conducted with the students of this university. The interviews were transcribed and analyzed according to the rigor of phenomenological research procedures involving ideographic and nomothetic analysis. This analysis has led us to three open categories: 1) Mathematics learning through TICs; 2) Technologies that have been used; 3) Teacher`s role. By understanding the open categories we have been able to grasp that the students -future teachers- admit feeling capable of using technology in their classes, however their testimonies in regards to the TIC`s have led us to believe that there would be a reproduction of the content studied at their time at college without using further reflection upon the subject or autonomy in order to create new projects for teaching Mathmatics using these TICs
