A perspectiva metodológica da resolução de problemas: um estudo sobre enunciados de situações matemáticas na EJA

In this paper we discuss the importance of a methodological perspective of solving problems as a sustaining process of teaching mathematics situated on the perspective of concept formation. Organizing a significant didactic situation for students imposes the need to study the interaction between them and the teacher and between them and their mathematical knowledge, learning environment in which the mere transmission of content gives way to contextualization, to historicizing and handling of topics from intuitive and everyday situations for the student. Thus, we understand mathematics as a fundamental language for the creation of theoretical thinking as a whole. We made use of documental analysis and classroom situations aiming at the use of instructional procedure related to the resolution of problems with the purpose of overcoming some representations about the process of teaching and learning mathematics which is strongly marked by imitative-repetitive algorithmic procedures. Considering mathematics as an investigation discipline, we point out renewal prospects for the curricula of this discipline, which are concrete in the movement of cultural action of the school itself as the cell generating discussion.

Atividades exploratório-investigativas em sala de aula de cálculo I com uso de tecnologia

This study presents the results from a qualitative resource, based on research-action methodology, which examined the innovate teaching practices implementations in the Calculus I during 2011 year. The analysis of collected data from three used sources – an initial questionnaire, an exploratory-investigative classroom, and an interview with some students at the end of the second semester – reveals that the students had appropriated of the technological recourses, using it as a tool to look for the knowledge. The investigative activities with the use of information technologies made the use of multiple representations in solving mathematical tasks, making the transition of numerical, algebraic and geometrical results possible for the students when they have looking for validation of their hypotheses and conjectures during mathematical problems solving. This works helped in the insertion of new practices in the discipline, and their results validate the proposal presented by the teacher, which is the discipline of Calculus use, whose character is strongly linked to the training content of the student, as a discipline whose can contributed to the pedagogical formation of the graduation student, leading him to know the Mathematical Education possibilities, specially the Mathematical Investigation - Solving Problems, in the outlook of dialogued classes where the teacher assumes the facilitator role and where the students become actives in their pursuit of knowledge

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

On the evaluation of the U(3) content of the matrix elements of one- and two-body operators

An expression for the U(3) content of the matrix elements of one- and two-body operators in Elliott's basis is obtained. Three alternative ways of evaluating this content with increasing performance in computing time are presented. All of them allow an exact representation of that content in terms of integers, avoiding Founding errors in the computer codes. The role of dual bases in dealing with nonorthogonal bases is also clarified. © 1992 American Institute of Physics.

O auxílio do software Geogebra na aquisição do conhecimento da função seno

This article aims to reflect on the qualitative analysis regarding the modification and the acquisition of new knowledge, as well as to identify the contribution of computer use in an intervention activity. It was used content analysis and it was created categories and units of analysis and from the frames containing the analysis of the categories it was randomly chosen four groups which led to their evaluation. Concerning to such frames of analysis and evaluation of the frequency of the records it was structured a metatext. The result of the analysis has shown the students' difficulty to realize their records, to express their interpretations and understandings in their mathematical activities by using the English language. It was noticed that the activity performed using the software Geogebra, based on the constructionist view, make possible the students to identify the modification and acquisition of new concepts.

Aprendizagem na contemporaneidade: jogos digitais no novo cenário em que caminha o ensino de química

Having in sight the current inertia found on the school physical environments as well as on the High School learning methods used, digital games appear as a different tool to build the individuals'/students' knowledge and becomes a driving factor for this research. The usage of this media resource tries to rescue a stimulant type of learning focused on the students' experiences while getting them closer to Science, Technology and Society (STS). The usefulness of this method falls short, however, without the capacitated guidance of a teacher. A literature review has been made about the possible schooling that electronic/digital games provide; it also brings the opinions of students and teachers to help comprehend how the insertion of this new tool in the classroom happens, as well as its efficiency and acceptance. Having in sight the relationship between individuals and the preoccupations about the future of mankind, components of humanity's destiny have been evidenced in the teaching of Chemistry. It is possible to conclude that these games can, indeed, help in the teaching process, although it is necessary that they develop a main didactic role, linked to the teaching of concepts and content, or else become only educational for that matter. Using the tools given by digital games it is possible, for example, through playfulness, to teach the theory of many abstract models, mathematical equations and chemical formulas, making it possible then to grab the students' attention, to thrill them and to develop their participation based on the experience they so often already have with cell phones and personal computers

Uma Proposta de utilização de um software educacional para o ensino de poliedros

This paper presents an educational proposal to use an educational software for the teaching of mathematics, following in the conduct of activities, the main aspects of sociocultural theory of Vygotsky. For this, it chose the Poly educational software, with which were developed teaching and learning activities for the polyhedra content provided in the São Paulo State Mathematics curriculum for the 7th year of elementary school. The objectives of this pedagogical proposal are to stimulate situations of social interaction among students and between students and the teacher, using an educational software as a mediator instrument and present a different way of using digital technology in math classes, aiming production of mathematical knowledge
