13. Desarrollo de la competencia de análisis de la idoneidad didáctica en futuros profesores de matemáticas
Abstract In this article we describe analyse and evaluate the implementation of an educational design to develop the prospective mathematics teacher’s didactical analysis and reflection competence. Planning of the experience, its implementation, and evaluation are based on the application of theoretical tools of the onto-semiotic approach. In several studi

14. Reduccionismo Didáctico y Creencias de Profesores acerca del Teorema de Pitágoras
Abstract In this paper, we report the results of an exploratory research in which the interest was to identify how beliefs that support teachers in service about the Pythagorean Theorem are indicators of a didactical reductionism on this mathematical result. Questionnaires were applied to five public high school mathematics teachers and a semi-structured int

15. ESTRUTURAS DE FULERENOS: ESTABELECENDO INTERFACES NO ENSINO DE MATEMÁTICA E QUÍMICA EM NÍVEL SUPERIOR
The objective of this paper is to study fullerene geometry properties and attempt to stablish a dialogue between the teaching of mathematics and chemistry concepts using hands-on cardboard geometric models, in classroom, in order to facilitate the understanding of fullerene structures. This approach to the study of such molecules represents a unique opportun

16. Conexiones Intramatemáticas y Extramatemáticas que se producen al Resolver Problemas de Cálculo en Contexto: un Estudio de Casos en el Nivel Superior
Abstract This paper reported a research which aims to identify connections that a university student group established to solve problems in a context. These problems can be solved using the relationship between the derivative and integral established in the Fundamental Theorem of Calculus. To identify such connections, we adopted the theoretical framework pr

17. Manifestaciones de los Profesores de Matemáticas sobre sus Prácticas de Evaluación de la Resolución de Problemas
Abstract Assessments are one of the organizers of the curriculum and should be part of the teaching and learning, as well as through the acquisition of learning. Together, we understand that problem solving is a learning objective, as reflected in the curriculum proposals, so that it becomes subject to evaluation. In our research we developed a questionnaire

19. Procedimientos Rituales en la Resolución de Ejercicios en Contexto Algebraico en Estudiantes de Profesorado de Matemática
AbstractIn a research about symbol sense (ARCAVI, 1994, 2007) in Pre-Service Mathematics Teachers that were studying the last year to become Mathematics Teachers, we detected the presence of ritual procedures (VINNER, 2000) while solving algebraic tasks. During the analysis of the answers to the applied questionnaire, we observed that some of the students so

22. Efeitos da formação de classes de equivalência sobre a solução de problemas de adição e subtração / Some effects of equivalence class formation over the solution of addition and subtraction problems
Research has shown that some properties of the additive problem may cause difficulties to solve it. The most important are: the problems presentation form, the semantic structure and the position of the unknown. Two experiments were conducted with some methodological differences, but both with the aim of investigating if the formation of an equivalence class

23. Técnica de realidade virtual para manipulação e deformação de superfícies NURBS
The Virtual Reality (VR) mainly deals with the creation of three-dimensional environments generated in real time and made available for multisensory interaction with different devices. A high processing capacity and modeling environments is required for applications of this nature. These applications currently extend to various productive sectors such as ind

Obstáculos à aprendizagem de conceitos algébricos no ensino fundamental: uma tentativa de aproximação entre os obstáculos epistemológicos e a teoria dos campos conceituais / Learning obstacles involved in the learning of algebraic concepts in elementary school: an attempt approach between epistemological obstacles and theory of conceptual fields.
The aim of this study is to examine obstacles and understand difficulties involved in the learning of Algebra in elementary school. The work consists in a review of the academic production and theoretical studies concerning the construction of the idea of obstacles, difficulties and errors in the learning of Mathematics in Brazil and overseas. The analyses o
