13. Estudio Exploratorio sobre Estrategias y Errores de un Estudiante con Trastorno del Espectro Autista al Resolver Problemas de División Partitiva
ABSTRACT: In recent years there has been an increasing interest in studying the academic performance of students with Autism Spectrum Disorder (ASD). Among school subjects, mathematics is one of the great obstacles that face students with ASD. It is therefore crucial to go in depth into the understanding that they develop on mathematical concepts, to later p

14. Inéditos-viáveis na formação continuada de educadoras matemáticas
Resumo: Este artigo resgata o conceito freireano dos inéditos-viáveis e analisa como eles são constituídos por educadoras que ensinam Matemática nos anos iniciais do Ensino Fundamental, a partir da formação continuada em serviço. Os inéditos-viáveis, enquanto conceito que favorece a explicitação de processos de aprendizagens matemáticas, remetem

18. Coupled monolithic columns as an alternative for the use of viscous ethanol–water mobile phases on chromatographic fingerprinting complex samples
ABSTRACT Concepts of sustainability have received attention from people involved in investigation of nature-derived matrices. The effects of concomitant pollutant activities are cumulative and harmful to the environment from which these matrices are obtained. High performance liquid chromatography analyses generate millions of litters of chemical waste world

19. Análisis de los Modelos Matemáticos Producidos durante la Resolución de Problemas de Fermi
Abstract In this paper, we present an analysis of written productions of 16 year-old students while solving Estimation Problems involving Big Numbers (EPiBN). This kind of problems is a particular type of Fermi problems and allows us to introduce modelling processes in Secondary school classrooms. Our analysis supports on the characterization of mathematical

20. Conocimiento Especializado del Profesor de Matemáticas acerca del Infinito
Abstract Infinity is a concept underlying many concepts present in school mathematics. In this article, we explore teachers' knowledge about infinity from the perspective of the professional knowledge, which is used to deal with infinity in a classroom. For that purpose, we use the discussion of vignettes of simulated situations where different kinds of unde

21. Estudio de las Actitudes hacia la Estadística en Estudiantes de Psicología
Abstract Statistics has been incorporated in most university courses and among them in the degree of Psychology, where the teaching of statistical concepts presents specific learning problems, because students enrolled have a very heterogeneous mathematical basis. In this work, we focus on the study of those students' attitudes for their influence on the lea

22. Integración de las Etnomatemáticas en el Aula de Matemáticas: posibilidades y limitaciones
Abstract This paper presents the first part of a doctoral research about teacher's training, focused on Ethnomathematics. It analyzed the veracity of two conjectures: C1. Teachers do not recognize mathematical extracurricular activities as math, and C2. This conviction obstructs the use of this knowledge in the classroom. Starting from these conjectures, we

24. 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
