La necesidad de personas alfabetizadas estadísticamente ha sido relevada en diferentes ámbitos de la sociedad. Sin embargo, el trabajo con datos tiene maneras de pensar que se distinguen de las usuales de la matemática y, no siempre, es evidente para el profesorado cómo desarrollar habilidades y conocimientos
en esta área tomando en cuenta la natur...
Statistical knowledge is culturally significant, making its integration into school curricula crucial. Educators, especially in statistical inference, face challenges. This study explores Chilean preservice mathematics teachers' perceptions of a lesson sequence on statistical significance, focusing on validity (theoretical consistency) and utility...
Statistical education at university level faces significant challenges, particularly with the rapid advancements in technology and evolving teaching methods. Updating teaching methodologies for statistics in higher education is essential. Information technologies can greatly enhance the learning of statistical content, but many existing platforms a...
Stochastic education of teachers has become an important research topic as mathematics teachers are usually responsible for statistics and probability teaching in schools. However, the emergence of new theoretical approaches has highlighted the problem of organizing and describing the professional knowledge needed to teach stochastics. The aim of t...
Instrumentos que permitan observar la Práctica Educativa son escasos, mostrando la necesidad de planteamientos claros en relación con la enseñanza de la matemática. El objetivo de este estudio es aportar con un modelo que permita observar la Práctica Educativa en profesores de matemática. Se emplea una metodología mixta que comprende dos fases, una...
Considerando que la promoción de una disposición positiva hacia la probabilidad y la estadística se ha establecido como una de las metas prioritarias de la corriente reformista en torno a su enseñanza en la escuela, en este trabajo, se adopta una perspectiva de género para abordar el objetivo de analizar las actitudes hacia la probabilidad y su ens...
Background: Stochastics’ teacher education has become an important research topic since mathematics teachers are usually responsible for the teaching of stochastics (statistics and probability) in schools. However, the emergence of new theoretical approaches has resulted in the identification of a problem: organizing and describing the necessary pr...
Civic statistics aims to promote work with statistics on social phenomena in educational contexts. We asked ourselves how viable civic statistics would be in the Chilean educational context. For this purpose, we analysed the curricular bases of the subjects Science for Citizenship, Citizenship Education and Mathematics for the last two years of com...
This research has the aim of proposing a guide that integrate the problems-situations regarding the understanding of random variable and their applications in probability distributions promoted by the Chilean School Curriculum, based on the ideas of Didactic Transposition and OSA’s primary mathematical objects (Ontosemiotic Approach to Mathematical...
La transnumeración, entendida como el cambio de sistemas de representación para generar nuevos conocimientos, es parte fundamental de la alfabetización estadística deseable como resultado de la escolarización. Debido a que su práctica profesional respecto a la educación estadística dependerá del razonamiento estadístico presente en de los futuros p...
Mathematics teachers are key agents in teaching stochastic at school, so we are interested in analyzing their knowledge of the content after completing their initial training. We conceptualized the knowledge of the content from the Teacher's Didactic-Mathematical Knowledge Model and following a quantitative methodology, we analyzed a sample of 269...
En este trabajo, exponemos los resultados de examinar la validez y estructura de la Escala de Actitudes hacia el Contenido de Estadística Descriptiva y su Enseñanza (EAEDE), con una muestra de 126 futuros profesores de matemática españoles y chilenos. Siguiendo una metodología cuantitativa, profundizamos en dar validación al instrumento en cuestión...
En la actualidad, las nociones de inferencia estadística se incorporan dentro de las orientaciones curriculares de diversos países, incluido Chile, donde se le atribuye gran importancia a la noción de muestra y a su selección (muestreo). Por ello, este artículo tiene por objetivo indagar qué comprenden los estudiantes chilenos que cursan su último...

This study relies on a theoretical perspective to provide a model that can be used to observe the educational practice of mathematics teachers. To this end, various existing observation instruments are studied, which, in the case of mathematics, aim to observe the teaching practice employed in the classroom, without considering the before and after...
Promoting positive student attitudes towards stochastics has become a core goal of statistics education reform, and we argue that this starts with the teachers during their teacher preparation program. Building on previous work assessing teachers’ attitudes, we focus on how pre-service teacher attitudes vary across different dimensions, and how the...
Recognizing that mathematics teachers are facing increasing demands in the teaching of probability and statistics (stochastics) at school level, we are interested in analyzing current pre-service teachers’ dispositions about content knowledge and attitudes towards the teaching and learning of stochastics. We implemented a quantitative study for a s...
En este trabajo presentamos el proceso de construcción e implementación piloto de un instrumento para evaluar el conocimiento sobre estocástica de futuros profesores de matemática, en lo referido al contenido de estadística descriptiva. Las pruebas se llevaron a cabo en una muestra de 126 futuros profesores de matemática en España y Chile. Los resu...
In this paper, we examine the attitudes towards descriptive statistics and its teaching in a sample of 126 prospective mathematics teachers from Spain and Chile. Following a quantitative methodology, we delved into analyzing the attitudes’ sense declared by the participants (negative or positive). Among the results, we begin by referring to the val...
La alfabetización estadística y probabilística es una prioridad en la formación de los ciudadanos, sobre todo en la actual situación de la pandemia de la COVID-19, en la que a diario nos vemos frente a la necesidad de interpretar información que de una u otra manera influye en nuestra toma de decisiones. Bajo esta mirada, en este articulo en la pri...
Background: Promoting a positive attitude towards teaching statistics and probability has become a shared challenge for teachers’ training today. Objectives: In this study we examined validity and reliability of Attitudes’ Scale towards Probability and its Teaching (ASPT) given by Estrada, Batanero, and Díaz. Design: Following a quantitative method...
Este trabajo presenta los resultados de la implementación de la Guía de Valoración de la Idoneidad Didáctica de procesos de Instrucción programados sobre Didáctica de la Estadística (GVID-IDE) en cuatro programas de asignaturas sobre didáctica o enseñanza de la estadística para profesores de matemática chilenos. Siguiendo una metodología cualitativ...
This paper analyzes the results of a scale of attitudes towards probability and its teaching and a scale of attitudes towards statistics and its teaching in a sample of 124 future teachers of Early Childhood Education from a university in southern Chile. The attitude is positive towards the probability in the teachers, although the attitude toward...
El interés mostrado en los últimos años por aunar la enseñanza de las matemáticas y las nuevas tecnologías por parte de los organismos oficiales nos ha llevado a plantearnos la necesidad de evaluar los recursos virtuales disponibles para la enseñanza de la probabilidad en educación primaria. La enseñanza de la probabilidad, dado su carácter experim...
In order to recognize the important role of teachers in the discipline's teaching and learning processes, in this article, we confront the problem of valuating the teaching planning in statistics didactics. For this, we describe the construction process of a guide that values its suitability according to a collection of indicators inferred through...
