Despite the possibilities of interactions and sharing information, only few studies investigated the use of messenger apps as a pedagogical tool. This paper reflects on possible uses of messenger app as a way to share and expand knowledge about the teaching and learning of statistics. The discussion is based on theoretical perspectives on statistics education, critical mathematics education and M-learning. A pilot study was conducted with early years elementary school Brazilian teachers. In this paper we discuss results from participants' responses to an online questionnaire. The results indicated that participants frequently use WhatsApp application and email on daily basis. Regarding the teachers' previous teaching of statistics, their responses suggested that they know about statistical graphs and they already approached pedagogical activities on statistical contents. Further stages of this study will explore in-service teacher education situations in which the use of Whatsapp might assist discussions and elaborations of pedagogical activities in school and extra-school contexts.

O artigo discute sobre uma pesquisa desenvolvida em escolas indígenas que teve como objetivo analisar as possibilidades de promoção do Letramento Estatístico no contexto intercultural do povo Xukuru do Ororubá, para fundamentar a ação docente e estimular o conhecimento matemático dos estudantes por meio de práticas reflexivas. Investigou-se se e como os conteúdos de Estatística eram trabalhados por professores dos anos iniciais do povo Xukuru e analisaram-se o planejamento e a realização de atividades em sala de aula envolvendo as etapas do ciclo investigativo no âmbito de um grupo colaborativo. Utilizou-se a observação participante, a entrevista semiestruturada com três professores indígenas, a análise documental em diários de aula de dois professores e a formação de um grupo colaborativo com a participação de 11 docentes dos anos iniciais do Ensino Fundamental. Constatou-se que os professores desta etnia, em termos gerais, desenvolvem um trabalho inicial com a Estatística, valorizando as características culturais da comunidade indígena com atividades interdisciplinares de construção de gráficos e tabelas e incluem também a pesquisa estatística por meio de atividades com intervenções nos diferentes espaços das aldeias. As vivências no grupo colaborativo possibilitaram experiências significativas sobre o ciclo investigativo, possibilitando a ampliação de habilidades.

In recent years, research on teaching and learning of statistics emphasized that the interpretation of data is a complex process that involves cognitive and technical aspects. However, it is a human activity that involves also contextual and affective aspects. This view is in line with research on affectivity and cognition. While the affective aspects are recognized as important for the interpretation of data, they were not sufficiently discussed in the literature. This paper examines topics from an empirical study that investigates the influence of affective expression during the interpretation of statistical data by final-year undergraduate students of statistics and pedagogy. These two university courses have different curricular components, which are related to specific goals in the future professional careers of the students. The results suggest that despite differing academic backgrounds in both groups, the participants’ affective expressions were the most frequent type of category used during the interpretation of research assignments.
