The diversity of vulnerability conditions, that have prevented children and adolescents from exercising their right to school education, also produces a diversity of cultural references of the public that comes to Basic Education programs for Youth and Adults in developing countries. This diversity often forges appropriation processes of numeracy…

In this article we present a reflection about the meaning attribution to the mathematical object "exponential function" that emerges from two mathematical modeling activities. The theoretical framework of the text contemplates considerations on Mathematical Modeling and elements of semiotics as theorized by Charles Sanders Peirce. The…

The study of questions has occupied a prominent role in the research into classroom discourse. For science teaching, questions are fundamental since they can connect students with the patterns of scientific thinking. In this article, we developed analytical tools to investigate the epistemic dimension of questions in chemistry teaching. We draw…

Young people around the world are calling ever more urgently on policymakers to address today's global challenges of sustainability, structural inequality and social justice. So it is little surprise that learning in a global society, understanding sustainable development and being active global citizens are increasingly popular themes for…

This article shows the intersections of right-wing conservative discourse and evangelical religious proselytism in shaping right-wing populist discourse in Brazil and its implications on the education policy in the last decade. Since re-democratisation in the 1980s, the policy path sought to guarantee progressive and inclusive public education,…

This paper discusses the social and political implications of the emergence of Portuguese-English bilingual education discourse in Brazil, which has been widely disseminated since the 1990s. Initially, a discursive analysis of prestige bilingualism concepts will be presented. Second, the issue of language policies will be addressed through the…

In this article, we focus on the contributions that a simulated jury-based activity might have for pre-service teachers, especially for their active participation and learning in teacher education. We observed a teacher educator using a series of simulated juries as teaching resources to help pre-service teachers develop their pedagogical…

In this paper, we present and apply a multi-level method for discourse analysis in science classrooms. This method is based on the structure of human activity (activity, actions, and operations) and it was applied to study a pre-service physics teacher methods course. We argue that such an approach, based on a cultural psychological perspective,…

There are primarily two discourses on slang: one is based on the Linguistic Purism View (slang is seen as an ugly, poor and/or dirty vocabulary); and on the other hand, the Socio-historical-cognitive view understands slang as a rich component of language (BARRA, 2007; MATTIELLO, 2005; ZARBALIYEVA, 2012). Taking this into consideration, this…

This article presents some of the results of a qualitative research project about the influences of the pedagogic strategies used by a mediator (graduate student in applied linguistics) in the supervision process of a Teletandem partner (undergraduate student in languages) on her pedagogical practice. It was done within the project…

Online discussions enabled preK-12 teachers (n = 125) from five nations (Brazil, Colombia, Ecuador, Paraguay, and the United States) to share their perspectives of culture and citizenship and the intersections of those concepts. Discussion moved between elements of personal and others' theory into effects of theory on practice. Teachers identified…

Purpose: The purpose of this paper is to show a practical case of dialogic web-based learning that has provided a set of questions analysing two complex technological projects in "southern" countries with effects on multicultural equity. Design/methodology/approach: Structured online review processes in multicultural and systems science…

Following queer theory and critical discourse analysis principles, my aims in this article are to analyze gay-themed discourses in literacy contexts and to suggest a way of queering literacy teaching. In the first part, I focus on ethnographically generated data from a class of fifth-graders in Brazil. The analysis shows that homoeroticism was…

In this paper, we draw upon a framework for analyzing the discursive interactions of science classrooms (Mortimer & Scott, 2003, "Meaning Making in Secondary Science Classrooms," Maidenhead, UK: Open University Press), to probe the movement between authoritative and dialogic discourse in a Brazilian high school science class. More…

This study involved fourteen semistructured interviews with teaching staff at a Brazilian university. These interviews were aimed at unveiling possible transformations caused by distance education in classroom teaching and in medical assistance practices. The discourses collected were analyzed using qualitative methods and divided into groups with…
