1. Correlação entre o Raciocínio Lógico e o Raciocínio Matemático em Crianças Escolarizadas
Resumo O objetivo deste estudo foi identificar possíveis relações entre problemas que envolvem raciocínios lógico e matemático no desempenho de 26 crianças, distribuídas em dois grupos (fortes e fracos, classificados inicialmente pelo seu desempenho em matemática - aritmética). O campo de pesquisa foi uma escola municipal de Ensino fundamental de S

2. The Influence of Statistical Anxiety on Statistic Reasoning of Pre-service Mathematics Teachers
Abstract The large number of statistical data present in everyday life makes statistical reasoning an absolute ability possessed by students. Meanwhile, the statistical reasoning is influenced by various cognitive and non-cognitive factors. This study emphasizes the influence of non-cognitive factors, which are the statistical anxiety. The purpose of this st

3. Desarrollo del Razonamiento Algebraico Elemental mediante Tareas de Recuento con Patrones
Abstract The counting tasks with patterns are a privileged context for the development of algebraic reasoning. The onto-semiotic complexity of tasks allows the identification of study processes to improve performance in successive algebrization levels, from purely arithmetic manipulation to a practice with a consolidated algebraic level. The objective is two

4. Intradisciplinaridade Matemática com GeoGebra na Matemática Escolar
Resumo Neste artigo discutimos o trabalho intradisciplinar na Matemática escolar e trazemos evidências de que o uso do GeoGebra o favorece. Para tanto, questionamos o processo de disciplinarização da ciência, que contribuiu com o aprofundamento das diversas áreas, ao mesmo tempo em que impulsionou uma crescente dissociação entre elas. De igual modo,

5. Conocimientos y competencia de futuros profesores de matemáticas en tareas de proporcionalidad
Abstract This paper describes the design and implementation of a training process about proportional reasoning with students of a Master’s Degree in Secondary Education in Spain. The main objective of the experiment is to explore their initial knowledge and to evaluate how competent the participants on analysing relevant aspects of the epistemic facet of t

6. Electromagnetism as a world view: implications for the teaching of energy
There are considerable differences in the ways mechanics and electromagnetism conceptualize energy. In the former, energy is defined in terms of force and work in a process-like reasoning that remits us to the ”past” of a given body or system. Moreover, in the mechanical framework energy is ascribed to matter, i.e., one speaks of the energy of a system o

7. Transitioning from “It Looks Like” to “It Has To Be” in Geometrical Workspaces: affect and near-to-me attention
Abstract Within a practitioner researcher framework, this paper draws on a particular mathematics education theory and aspects of neuroscience to show that, from a learner’s perspective, moving to a deductive reasoning style appropriate to basic Euclidean geometry, can be facilitated, or impeded, by emotion and/or directed attention. This shows that the is

8. Sample size: how many participants do I need in my research?
The importance of estimating sample sizes is rarely understood by researchers, when planning a study. This paper aims to highlight the centrality of sample size estimations in health research. Examples that help in understanding the basic concepts involved in their calculation are presented. The scenarios covered are based more on the epidemiological reasoni

9. Conocimiento de matemáticas especializado de los estudiantes para maestro de primaria en relación al razonamiento proporcional
A particular domain of mathematical knowledge for teaching is the specialized content knowledge. This study focuses on examining pre-service primary school teachers' mathematical content knowledge related to proportional reasoning. Results show that pre-service teachers' mathematical content knowledge is limited. These results are supported by pre-service te

10. Valoración de la idoneidad epistémica y cognitiva de un proceso de instrucción en la resolución de problemas bayesianos
This paper aims to present the assessment of an instructional process about the Bayes Theorem carried out with 50 Engineering students in a Statistics class of the Universidad Nacional de Mar del Plata. Under the theoretical and methodological framework of the Ontosemiotic Approach to Mathematical Cognition and Instruction, this assessment is done in epistem

11. On the status and role of instrumental images in contemporary science: some epistemological issues
The controversy over imageless thought versus picture thinking (especially via mechanical models), with the recent reconsideration of model-based reasoning in the physical sciences is briefly examined. The main focus of the article is on the role of instrumentally elicited images (scopic instruments, cameras, CCDs) in the sciences, especially in the physical
