Geoff is the skipper of and Jill a crew member on
*Jeannie*, a J35 racing yacht. When not sailing, they are mathematics educators.
After graduate work at the University of Waterloo,
**Geoff Roulet** began teaching mathematics, computer science, and chemistry at Roland Michener Secondary School in Timmins, northern Ontario. In the late 1970s, when personal computers for computer science were placed in the back of his classroom, Geoff began using these to support student learning in mathematics. Since then he has been involved in ICT use in teaching and learning at all grades and in all subjects, but with a particular focus on mathematics. Teaching was followed by a short spell of curriculum development and support work with the Ontario Ministry of Education and then in 1990 a move to the Faculty of Education, Queen's University at Kingston. Along the way Geoff completed M.Ed. and D.Ed. degrees at the Ontario Institute for Studies in Education (OISE) at University of Toronto. Geoff's present research is focused on web-based environments for the collaborative construction of knowledge.
Through her experiences in secondary school mathematics,
**Jill Lazarus** developed an appreciation for mathematics. This led her to pursue further studies at the undergraduate level. After her second year in the undergraduate program at Nipissing University, Jill was invited to participate in an Ontario Mathematics Curriculum analysis project, an opportunity that sparked her interest in mathematics education research. This led her to Queen’s University where she completed a thesis titled Translating Messages from Curriculum Statements into Classroom Practice: Communication in Grade 9 Applied Mathematics. At Queen’s, Jill worked under the supervision of Dr. Geoffrey Roulet. Since the completion of her degree in 2008, she has remained involved in mathematics education activities in Ontario and has been working as a teacher to make mathematics meaningful for her own students. Since completing her M.Ed. degree, Jill has continued to collaborate with Dr. Roulet, whose expertise has been invaluable for helping her explore the potential of information and communication technologies for engaging students in mathematics.

This discussion centers on the use of computer tools in a high school class. The goal was to develop a “math-talk learning community” to establish mathematics communication and collaboration as a classroom norm. In support of this we have combined the use of a wiki, GeoGebra, and Jing.
We would like to invite educators who have experience with wikis, GeoGebra and screencasts, or who would like to learn more, to discuss our project and share their ideas.
