Cornelia Hoogland, Daniel Jarvis, George Gadanidis & Tara-Lynn Scheffel, University of Western Ontario, Canada

We present a study of over 100 middle school pre-service teachers' online discussions of mathematical beauty. The goal of the study is to identify how the pre-service teachers perceive mathematical 'beauty'. The pre-service teachers were part of a...

Designing Digital Windows into Mathematics
World Conference on Educational Multimedia, Hypermedia and Telecommunications(EDMEDIA)2007:1

George Gadanidis, Faculty of Education, University of Western Ontario, Canada; Rick Jardine & Kamran Sedig, Faculty of Science, University of Western Ontario, Canada

In this paper we discuss the design goals of a set of Digital Windows into Mathematics (DWMs) that we are in the process of developing. Our goal is to create DWMs whose multimedia-rich content will challenge and disrupt typical assumptions about...

New media and research dissemination: the case of performing mathematics education research
Journal of Educational Multimedia and Hypermedia(JEMH)22:1, February 2013

George Gadanidis, Faculty of Education, Western University, Canada; Marcelo Borba, Universidade Estadual Paulista, Brazil

"** Invited as a paper from ED-MEDIA 2011 **" Academic research is typically written in a style and for venues that remain largely inaccessible by the general public and even by the practitioners who might benefit from it. In this article we...

Learning objects and the level of mathematical thinking
World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education(ELEARN)2003:1

George Gadanidis, Faculty of Education, Canada

In this paper we propose a scheme for classifying the mathematical thinking facilitated by learning objects. With references to examples of existing learning objects, we describe four levels of mathematical thinking: 1 = recalling, 2 = applying, 3 = ...

‘Mathematical Romance’ and the Online Education of Elementary Pre-service Teachers
Society for Information Technology & Teacher Education International Conference(SITE)2003:1

Cornelia Hoogland, Dan Jarvis & George Gadanidis, University of Western Ontario, Canada

Pre-service elementary mathematics teachers need romantic experiences with mathematics - opportunities to (re)discover the pleasure in mathematics and the beauty in mathematical thinking. In this paper we report on our research on pre-service...

Pre-service Mathematics Teacher Lesson Planning with Online Applets
Society for Information Technology & Teacher Education International Conference(SITE)2003:1

Karen Schindler & George Gadanidis, Faculty of Education, University of Western Ontario, Canada; Janette Gadanidis, Thames Valley District School Board, Canada

This paper reports on a study of pre-service teachers' pedagogical thinking when using online applets in their lesson planning. The applets used in the study helped facilitate the exploration of mathematical relationships in the areas of linear...

Genesis, use, reuse and transformation of a learning object
World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education(ELEARN)2003:1

George Gadanidis, Faculty of Education, Canada

Learning objects are touted as reusable. But what exactly do we mean by 'learning object' and by 'use' or 'reuse'? In this paper I compare and contrast the genesis, use, reuse and transformation of two mathematics learning objects. In describing and ...

“Sing me a Good Math Story”: Using Online Music Videos to Share Students’ Classroom Mathematics
World Conference on Educational Multimedia, Hypermedia and Telecommunications(EDMEDIA)2010:1

George Gadanidis, Faculty of Education, University of Western Ontario, Canada; Janette Hughes, Faculty of Education, University of Ontario Institute of Technology, Canada

In this paper we explore a case study of third grade students writing dramatic scripts to communicate their math learning with a wider community. The dramatic scripts are written in small groups, acted out for peers, performed for family and friends,...

The Effect of Interactive Applets in Mathematics Teaching
World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education(ELEARN)2002:1
