This paper focuses on two third-grade students' work on the same statistical question whereby one acts with analogue material and the other with TinkerPlots™. The aim of the research was to find out whether different material influences the actions and, thus, possibly the mathematical interpretations of the learners. To investigate this research…

This paper adopts a semiotic perspective on mathematical learning according to Peirce, in which the actions on material arrangements are considered the bases for diagrammatic work. The focus is on the learner's actions using digital and analogue material arrangements which are the starting point for the reconstruction of the learner's mathematical…

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 theorization of how multimodal learning intersects with online teaching environments has emerged as a key research area in relationship to the creation of opportunities for L2 online interaction. However, there are few studies which have examined how cross-cultural dyads harness and orchestrate semiotic resources across mobile technologies…

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…

This paper is a mathematical (Boolean) analysis a set of cognitive maps called Thinking Maps[R], based on Albert Upton's semantic principles developed in his seminal works, Design for Thinking (1961) and Creative Analysis (1961). Albert Upton can be seen as a brilliant thinker who was before his time or after his time depending on the future of…
