Uma análise fenomenológica do uso de jogos e materiais manipulativos no ensino de matemática

This work investigates the reasons that take teachers to use or not use manipulative materials in mathematics education as well as the knowledge that teachers of Basic Education schools of the city of Guaratingueta have about such resources. The experience in the classroom, while participating in projects, showed that these resources are important allies in knowledge production. However, we noticed that they are not often present in the teachers teaching practice. This leads us to investigate the relevance of such education resources from authors like Grando (2000) and Macedo (2012) and try to see the idea that math teachers have about their use. For this research we developed a questionnaire and we headed teachers to obtain data. Assuming a posture qualitative with phenomenological approach, organized researched data and interpreted following the procedures described by Bicudo (2011) and Machado (1994). We built three categories or regions of generality that lead us to consider that, for our research subjects, the use of manipulative materials is significant as Didactic Resources and Learning Aid, however, used from a Naïve Knowledge that does not involve reflection on practice or relies on theoretical concepts

O jogo de xadrez e a aprendizagem matemática: uma análise de possibilidades

The idea of this research is to analyze the possibilities of using chess as a nice alternative for motivating and teaching mathematics. The study was carried out in three steps, consisting of a literature review about the importance of games for education, followed by the importance that the game of chess has on the student's cognitive development and, finally, a qualitative analysis of data obtained by recording it. The data were taken from some activities performed in the 6th grade class of elementary education at a public school in the city of Roseira, state of São Paulo, in a team at the age 9 and 12 year-old students. The result of this research proved to be significant the use of chess game to teach math, we were able to verify that there was an easy assimilation of the subject, because when a student plays, he/she willdevelop skills in the game which becomes an incentive to study even more

A etnomatematica e suas contribuições para o conteúdo da matemática escolar

In this research we set out to understand the Ethnomathematics Program such as it is said by some authors of Mathematics Education. To this end we conducted an exploratory study. The objective of to study this program is to analyze its contribution to understanding of the content of mathematics in the school environment. The authors studied are Ubiratan D'Ambrosio, considered the precursor of the Ethnomathematics Program and researchers as Paulus Gerdes, Maria do Carmo Santos Domite, Eduardo Sebastiani Ferreira and Gelsa Knijnik, that develop research in Ethnomathematics and may contribute to the comprehension of what in the study we intend to do. Although recourse to authors of Education and Education Philosophy as Maria Aparecida Viggiani Bicudo and Joel Martins to intend the idea of curriculum and its importance in the school environment. The study carried showed that the Ethnomathematics Program goes beyond of to explicit the mathematical knowledge produced by cultural groups, transcending the description of procedures that reveal the construction of knowledge hitch to school subjects. That is, the program seeks the valuing the human being, concerning itself with the construction of a worthy citizen and able to relate with their natural environment, social and intellectual

Laboratório de Ensino de Matemática: uma extensão da sala de aula

This work has as purpose to present some boardings that assist in the process of mathematics teach-learning. We detach the Laboratory of Education of Matemática (LEM) and its main components. On the basis of the National Curricular Parameters, we display four activities that had been developed and applied in a Municipal School of the Public Net of Education in the city of Roseira. In the activities the mental arithmetic is developed, to study the elementary operations and concepts of horizontal segment and vertical segment. The results show that, with the development of the activities, as much the researcher as the teacher and its pupils had been more interested in arguing, teaching and to learn mathematics

Aspectos envolvendo as atitudes negativas de alunos com relação à matemática no primeiro ciclo do ensino fundamental

A matemática é vista pela maioria das pessoas como a disciplina escolar mais difícil. Muitas pessoas a vêem, desde muito cedo, como um “bicho de sete cabeças”, e pais e alguns professores, muitas vezes, colaboram com essa situação. Considerando que muitas investigações envolvendo as atitudes dos alunos em relação à matemática já foram realizadas na área da Educação Matemática, o objetivo desta pesquisa foi sistematizar os principais resultados nelas apresentados. As atitudes negativas dos alunos em relação à matemática estão associadas a quais aspectos? Esta será a questão norteadora da investigação. Mais especificamente, foi realizada uma pesquisa qualitativa bibliográfica sobre as atitudes dos alunos do primeiro ciclo do Ensino Fundamental em relação à matemática. A partir dela, elencamos e analisamos, em oito pesquisas selecionadas, motivos que podem estar associados às atitudes negativas dos alunos em relação à matemática. Para tanto, utilizamos o banco de teses e dissertações da Capes, bem como outros trabalhos recentes como fontes de investigação.. Parte significativa dos estudos reforça a relação entre as atitudes dos alunos frente à Matemática e os aspectos envolvidos no processo de ensino e aprendizagem dessa disciplina e todos eles apontam o papel do professor como principal responsável pelas atitudes positivas e/ou negativas apresentadas pelos alunos com relação à matemática, ainda que a família também tenha sido citada como relevante no processo

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

Resolução de problemas no ensino da matemática: uma experiência com base no rali matemático

Since the 1980s, problem solving has been recommended by international curriculum proposals for the teaching of mathematics. In Brazil, with the publication of the National Curriculum Guidelines in 1997, this trend was reinforced and became the central activity of the classroom. Troubleshooting is seen as an asset in the learning process of the student, providing a context for learning concepts, mathematical methods and attitudes. However, this methodological approach requires deeper research, especially for new teaches. This work aims at a further study in this subject and in the experiences with problem solving in the classroom of High School students. The ground basis for this was the Mathematical Transalpine Rally, a competition between classrooms that seeks to facilitate the problem solving within mathematics teaching, and through an autonomous and creative work, performed collectively. The results of this experience, as well as the contribuition for the student’s education are presented

Etnomatematica: psicologia aplicada à educação matemática

Investigations in ethnomathematics show that there are several cultural forms of mathematics, mathematics different dominant. Currently, most research in ethnomathematics aim an ethnographic study of anthropological or cultural groups. However, there is a strong need for studies in ethnomathematics is to target the pedagogical action, involving the teachinglearning practices. So the big challenge for researchers in ethnomathematics is the development of study and teaching practices in line with the objectives philosophicaltheoretical Program Ethnomathematics

A evolução na prática da educação: o uso das mídias como ferramentas no ensino/aprendizagem da educação matemática

It is possible to note that the teaching done in the usual way goes against the language of youth today. It is essential that there be incentives and subsidies regarding the use of such media, whether the responsible government agencies and their members, be they principals and teachers, so there is a reform in the existing educational models and teaching. Currently, teaching is in a purely encyclopedic context of teaching models with pre-defined, ignoring the teaching based on the context in which the student lives (ethnomathematics). The objective of this work is to show how the use of audiovisual best known, such as newspapers, magazines, TV and computers can assist in teaching and learning of mathematics education, making teaching more enjoyable and inserted into the day-to-day student

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

Modelagem matemática aplicada a precificação de opções

The mathematical models are critical to determine theoretical prices of options and analyze whether they are overrated or underrated. This information strongly influence in operations carried out by the investor. Therefore, it is necessary that the employee model present high degree of reliability and be consistent with the reality of investment to which it is intended. In this sense, this dissertation aims to apply the steps of mathematical modeling in the Pricing of options for decision making in the investment of a hydroelectric power plant. Was used a Monte Carlo simulation, with the Latin Hypercube Method, to determine the volatility of returns of the project. In order to validate the proposed model, compared to the results found by the Binomial Model, which is one of the models most used in this type of investment. The results reinforce the hypothesis that the mathematical modeling with the Binomial Model is critical to investment decision-making in hydroelectric power

As avaliações externas e suas implicações para a organização do trabalho numa escola da rede estadual paulista: um estudo de caso

This research analyses the positives and/or negatives of external reviews to work's organization developed at the/and by the school. It should be noted that it's a qualitative case of empirical research, and it takes the pattern of case's study, because we held the investigation just in one school, which in turn, belongs to the education's public network by the state, and is located at the São Paulo northwest. The tools employed at this research for the data's collect were the observation, restricted to times of Pedagogical Work Activities Collective from the school, and the semi structured interviews with educational coordinators and the teachers too. We choose educational coordinators and teachers because they are closer with the education and learning methods, as well as their activities have more responsibility in relation to the main function developed by school, that is to teach, in other words, educational processes. This research also concerns an investigation about the educational coordinators and teachers conceptions, in relation to system's implantation external reviews at the schools. The results indicate to incidence of significant interference of the external reviews to/in the organization school's work, as, a teaching practice reorientation from results arising these reviews, or, modifications in the internal rating, since they have followed a tendency towards becoming more similar with their own external reviews. In what concerns the subjects investigated, we can emphasize that mostly submitted alienation with respect to negative effects of the external reviews for school. They showed that are conformed with the reality that they are inserted and in your mostly they proved perceive the positive effects by the implantation of external reviews. We can also add that the data obtained in the research allow us declare that the work of the educational coordinators of this school in presence of external reviews don't...
