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…

Despite significant research exploring students' quantitative reasoning, few studies have explored the semiotic processes that mediate its development. In this report, we present a case study to show how one student constructed a semiotic chain for a quantity as he worked with a mathematical task. Importantly, we connect frameworks for…

Purpose: The purpose of this paper is to examine the ways in which early adolescent programmers embed meaning in their digital media created within an online programming community called Scratch. Design/methodology/approach: The author completed an 18-month descriptive case study with 5 early adolescent participants. The research design included a…

Based on a study of the digital literacy practices of immigrant Filipino students in Vancouver, this paper focuses on how learners with unequal access to resources engage with different tools to locate information and find opportunities for language learning online. Data was collected through interviews and observations of participants as they…

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…

According to the National Council of Teacher of Mathematics (NCTM) (2000), K-12 students should be given an opportunity to develop their spatial reasoning abilities. One of the topics that may allow students to develop their spatial skills is forming 3-dimensional objects using spinning and extrusion methods. Also, extrusion and spinning methods…

A curriculum is a form of politics (Apple, 1993). The politics of a curriculum defines what is legitimate and valued and what is not. In Taiwan, the objectives of vocational high school (VHS) education are to prepare students to acquire relevant professional knowledge and practical skills and to integrate them into their future career development.…

This paper draws from research conducted as part of an Australian Research Council funded Linkage Project "Teaching effective 3D authoring in the middle years: multimedia grammatical design and multimedia authoring pedagogy", which is a collaboration between the University of New England, the University of Tasmania and the Australian…

The purpose of this interpretive case study was to explore--through a close analysis of one class project--students' use of audio signs and the teacher's scaffolding of the use of audio signs. Two research questions guided this study: (a) In what ways did the fifth-grade students use audio signs, specifically transitions sounds, when constructing…

This is a qualitative case study of two students' composing processes as they developed a documentary video about the Dominican Republic in an urban, public middle school classroom. While using a digital video editing program, the students moved across multiple media (the Web, digital video, books, and writing), drawing semiotic resources from…

This document contains the fourth volume of the proceedings of the 30th Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Mathematics at the Centre." This volume features 59 research reports by presenters with last names beginning between Kun and…
