1. A interpretação dos resultados: um elemento de significado para inferência estatística
RESUMO Em dois problemas de resposta aberta, onde um teste de hipótese e uma análise de variância elementar são modelados, analisamos as respostas de (N = 224) estudantes de psicologia da Universidade de Huelva, Espanha, em relação ao significado alcançado pelos alunos na interpretação dos resultados. Uma vez resolvidos, eles foram solicitados a int

2. Um estudo exploratório das tensões nos critérios de seleção de problemas em professores do Ensino Fundamental
RESUMO A resolução de problemas é considerada central na aprendizagem e no ensino da matemática escolar. Sua implementação nas salas de aula, no entanto, tem sido elusiva e difícil. Um dos fatores identificados como responsáveis foram as concepções dos professores sobre o processo de resolução de problemas, nos quais são valorizados e relacionad

3. Optimization in timetabling in schools using a mathematical model, local search and Iterated Local Search procedures
Resumo Este artigo aborda o problema de otimização na geração da grade horária escolar. Tal problema consiste em definir os dias e horários das disciplinas a serem ministradas por cada um dos professores de instituições de ensino. Para isto foi desenvolvida uma ferramenta que faz uso de técnicas de Pesquisa Operacional (PO), com foco na geração e

4. Tipos de Problemas que Provocan la Generación de Argumentos Inductivos, Abductivos y Deductivos
Abstract This paper presents a relation between the types of conjecturing open problems in geometry, preferably solved using Dynamic Geometry Systems, and the types of arguments produced. The aim of this paper is to show how each type of problem can elicit the production of certain types of arguments (inductive, abductive, and deductive) during the problem-s

5. Numerical experiments with the Generalized Finite Element Method based on a flat-top Partition of Unity
Abstract The Stable Generalized Finite Element Method (SGFEM) is essentially an improved version of the Generalized Finite Element Method (GFEM). Besides of retaining the good flexibility for constructing local enriched approximations, the SGFEM has the advantage of presenting much better conditioning than that of the conventional GFEM. Actually, bad conditi

7. Los Métodos de Resolución de Problemas y el Desarrollo del Pensamiento Matemático
Abstract In recent years, we have reached a certain consensus about the role of teaching mathematics in the development of thought, above the transfer of mathematical knowledge. In this sense, the attention to the development of the ability to solve problems is giving way to thought development in problem-solving. Many authors have provided methods to solve

8. MODELING AND SOLVING A RICH VEHICLE ROUTING PROBLEM FOR THE DELIVERY OF GOODS IN URBAN AREAS
ABSTRACT This work addresses a vehicle routing problem that aims at representing delivery operations of large volumes of products in dense urban areas. Inspired by a case study in a drinks producer and distributor, we propose a mathematical programming model and solution approaches that take into account costs with own and chartered vehicles, multiple delive

9. Creencias de formadores de profesores de matemática sobre resolución de problema
Abstract Problem solving is seen as a major mathematical learning opportunity, especially in the pre-service teacher education, where educators play a key role in the students understanding. Considering at least three approaches to problem solving (process, objective method of instruction), this research addresses the beliefs of a group of teacher educators

10. A NEW MATHEMATICAL MODEL FOR THE WORKOVER RIG SCHEDULING PROBLEM
ABSTRACT One of the most important activities in the oil and gas industry is the intervention in wellsfor maintenance services, which is necessary to ensure the constant production of oil. These interventions are carried out by workover rigs. Thus, the Workover Rig Scheduling Problem (WRSP) consists of finding the best schedule to service the wells while con

11. El Consentimiento con el Otro en la Interpretación de la Comprensión en Matemáticas
Abstract Recognizing the mathematical activity as an interpretative process forces us to give an operative answer to the problem of reference in the interpretation. In this work, we propose to situate this reference in the consent with the other, a visible trace complementary to the use of the mathematical knowledge that we include in the hermeneutical dimen

12. Modelo de Competencias Profesionales de Matemáticas (MCPM) y su Implementación en Profesores de Enseñanza Primaria en Chile
Abstract This research project analyzed primary school teachers from 7th grade (second-cycle) enrolled in training through a Model of Professional Competences in Mathematics. The aim of the project was to develop and implement a teaching methodology that relates mathematics and pedagogical knowledge and teaching practice, with a view to updating mathematics
