This submission contains the Proceedings of the 2002 Annual Meeting of the Canadian Mathematics Education Study Group (CMESG), held at Queen's University in Kingston, Ontario. The CMESG is a group of mathematicians and mathematics educators who meet annually to discuss mathematics education issues at all levels of learning. The aims of the Study Group are: to advance education by organizing and coordinating national conferences and seminars to study and improve the theories of the study of mathematics or any other aspects of mathematics education in Canada at all levels; and to undertake research in mathematics education and to disseminate the results of this research. These proceedings include plenary lectures, working group reports, topic session descriptions, new PhD reports, and summaries of ad hoc and special anniversary sessions. Papers include: (1) Toward a Practice-Based Theory of Mathematical Knowledge for Teaching (Deborah Ball and Hyman Bass); (2) The Experimental Mathematician: The Pleasure of Discovery and the Role of Proof (Jon Borwein); (3) Mathematics and the Arts (Susan Gerofsky, Nathalie Sinclair, and Brent Davis); (4) Philosophy for Children and Mathematics (Richard Pallascio and Elaine Simmt); (5) The Arithmetic/Algebra Interface: Implications for Primary and Secondary Mathematics / Articulation arithmetique/algebre: Implications pour l'enseignement des mathematiques au primaire et au secondaire (Nadine Bednarz and Lesley Lee); (6) Mathematics, the Written and the Drawn (David Pimm and Nick Jackiw); (7) Des cours de mathematiques pour les futurs (et actuels) maitres au secondaire / Types and Characteristics Desired of Courses in Mathematics Programs for Future (and In-Service) Teachers (Walter Whiteley, Peter Taylor, and Harry White) [Presented in both French and English]; (8) High School Mathematics Teachers' Perspectives of Mathematical Word Problems (Olive Chapman); (9) What are Critical Online Experiences for Mathematics Teachers and Students? (George Gadanidis); (10) Socioeconomic Gradients in Mathematics Achievement: Findings for Canada from the Third International Mathematics and Science Study (George Frempong); (11) Light and Shadows (in) Knowing Mathematics and Science (Kathleen Nolan); (12) Supporting Student Efforts to Learn with Understanding: An Investigation of the Use of "JavaSketchpad" Sketches in the Secondary Geometry Classroom (Margaret P.
