Alas, this volume cannot possibly convey the spirit of the meeting it reports on. It can merely describe the content of activities without giving much of the flavour of the process. Therefore, this introduction will attempt to tell you a little about our organization, and about our meetings. CMESG/GCDEM is unlike other professional organizations: One belongs to it not because of who one is professionally, but because of one’s interests. And that is why our members come from mathematics departments and faculties of education, from universi- ties and colleges, and from schools and other educational institutions. What unites them is an interest in mathematics and how it is taught at every level, and a desire to make teaching more exciting, more relevant, and more meaningful. Our meetings are unique, too. One does not simply attend a CMESG meeting the way one attends other professional meetings, by coming to listen to a few chosen talks. You are immediately part of it; you live and breathe it. And, even though the format, embedded in tradition, does not change much from year to year, there are
