Social semiotic discussions about the role played by representations in effective teaching and learning in areas such as physics have led to theoretical proposals that have a strong common thread: in order to acquire an appropriate understanding of a particular object of learning, access to the disciplinary relevance aspects in the representations…

Literacy as a unified concept is no longer valid or useful for today's complex world, where globally we face many challenges and contradictions. Adult literacy is shifting rapidly, and the human need for visually communicating meaningfully and relationally -- beyond 'reading and writing' -- is vital for addressing wicked problems and difficult…

Background: Science teaching and learning, as discursive practices, occur through the utilization of various semiotic modes. Gestures play a pivotal role as an embodied mode that acts in conjunction with speech in oral communication settings, such as classrooms. Previous research on gestures in chemistry and science education has illuminated how…

This article aims to investigate the teaching of chance in the context of tactile models (TM) from the perspective of the Theory of Register of Semiotic Representations. In this qualitative research, we sought to identify the different types of semiotic registers and transformations (treatment and conversion), in the solutions of the tasks of the…

Research on translingual repertoires has highlighted the diverse semiotic resources that individuals access in communication, but little research has considered how spatial factors permit or limit access to these resources. Furthermore, as translingual studies have predominantly focused on interactional analysis, there is a paucity of studies on…

The objective of this article is to identify the meaning attributed to the didactics of mathematics and what are the criteria with which an improvement in the teaching and learning process of mathematics is based, future teachers of mathematics, belonging to universities in three different countries (Brazil, Chile, and Ecuador). The qualitative…

Cosmopolitanism theory was mostly developed separately from the study of multilingualism: while language is central to cosmopolitanism as a practice, only a few scholars focusing on cosmopolitanism have taken a language-centred approach. We further theorise the relationship between cosmopolitanism and translingual practice with our focus on…

This exploratory study focuses on changes in the accomplishment of requests by an adult English as an additional language speaker/ learner interacting on WhatsApp for nine months. The analysis follows a microanalytic approach to digital interaction informed by recent developments within longitudinal conversation analysis. It unpacks the array of…

This paper examines the implications and implementation of official language policy designed to support endangered Indigenous languages in the municipality of São Gabriel da Cachoeira, Amazonas, Brazil. The policy, in place since late 2001, declared three of the region's many Indigenous languages (Nheengatú, Tukano, and Baniwa) to be…

The aim of this study is to better understand how teachers use various embodied semiotic modes -- speech, gestures, gaze, and proxemics -- when they present scientific content to the entire class. To analyse the multimodal practices of these teachers, we integrated the social semiotic theory of multimodality and the joint action theory in…

The relevancy of linear algebra (LA) in different areas and also the difficulties faced by undergraduate engineering students studying this content are well known. Grounded on this premise, we aimed at articulating papers related to the teaching and learning of LA in engineering undergraduate programs through a mapping of the main investigations…

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…

This paper focuses on Luan's race performances both on the web and in classroom interaction. Luan is a black young man, who identifies himself as gay. The study is part of a multi-sited ethnographic piece of research on a group of high-school students in the state sector, in the "periphery" of a town on the Rio de Janeiro State north…

This dissertation explores the way Kotiria/Wanano (E. Tukanoan, Kotiria hereafter) women of the Brazilian "Alto Rio Negro" (ARN) contrive (McDowell 1990) "kaya basa" "sad songs" using linguistic and musical resources to construct songs that express loneliness and other private emotions, while also creating alliances…

Digital artifacts have the potential for augmenting the interest of students and the quality of learning environments. However, it is still common to find technology being inserted in learning settings without a closer connection to the learners' contemporary world. In this paper we report on results of a qualitative research conducted to address…
