In this research, we investigated whether the use of GeoGebra Augmented Reality (AR) can foster students in conceptualising a mathematical object by manipulating its different semiotic representations. We designed and implemented, with thirty university mathematics students, a teaching sequence on paraboloids using GeoGebra AR supported by…

This study explores university students' understanding of the relationships between formal definitions of the limit of a function and the limit of a sequence in terms of the accumulation point in a technology-enhanced collaborative learning environment. The participants of this study are 17 prospective mathematics teachers. The data are collected…

Collaborative Video Annotation (CVA) is a kludge where learners annotate video together, experiencing both the video and each other's annotations in a dynamic discussion. Three scenes from small group CVA discussions were selected for analysis from 14 CVA discussions where 8-12 learners interacted via the annotation tool on top of a video. The…

This study describes an approach to history education which leverages augmented reality (AR). Currently, most learning interventions with AR are designed from the paradigm of an expert-led model of teaching, where the AR artefact is created by a domain expert; under such a paradigm, the learner has limited ownership of the process of artefact…

Presentation is the default mode of communication in higher education. Teacher education is no exception, and student teachers learn the practice of presenting by observing their subject teachers and by performing their own presentations. This study proposes an analytical framework based on the Learning Design Sequence (LDS) (Selander, 2008),…

The aim of this research is to analyse students' sense-making regarding matrix representation of geometric transformations in a dynamic geometry environment (DGE) within the perspective of semiotic mediation. In particular, the focus is on students' reasoning on the transition from the notion of function to transformation and to matrix…

Grounded in the three-tiered transdisciplinary SLA framework of the Douglas Fir Group (2016), we explore how the concept of 'semiotic resources' may be integrated into CALL activity designs. Starting at the macro level, we discuss how language ideology may influence where to situate semiotic resources within initial design considerations. We next…

The purpose of this research is to investigate the practice of intertextuality of Farah (pseudonym) a 20-year-old female university student who engaged in a variety of culturally shaped digital literacy practices. In particular, it seeks to elucidate how Farah's practice of intertextuality serves as a semiotic mediation for her exercise and…

This study examines the language practices of Chinese visiting scholars on WeChat and explores the representational meanings of their translanguaging practices. An ethnographic approach combining with systematic observation, WeChat screenshot data and interviews with Chinese visiting scholars is adopted to get hold of the richness of situated…

Previous research on classroom interaction in international university contexts tended to focus on individual speakers' language (in)competence. This paper adopts a translanguaging and spatial orientation to intercultural classroom interaction and highlights the role of situated assemblages of linguistic, semiotic and multimodal resources embedded…

In this paper, we propose a social semiotic approach to studying PowerPoint in university classrooms. Our approach is centred on two premises: (1) PowerPoint is a semiotic technology that can be integrated into the pedagogical discourse of classrooms, and (2) PowerPoint technology encompasses three interrelated dimensions of social semiotic…

PowerPoint knowledge presentation as a digital genre has established itself as the main software by which the findings of theses are disseminated in the academic settings. Although the importance of PowerPoint presentations is typically realized in academic settings like lectures, conferences, and seminars, the study of the visual features of…

Slowmation is a twenty-first century digital literacy educational tool. This teaching and learning tool has been incorporated as an assessment strategy in the curriculum area of science and mathematics with pre-service teachers (PSTs). This paper explores two themes: developing twenty-first century digital literacy skills and modelling best…
