Topic Study Groups
As the name suggests, a Topic Study Group is designed to gather a group of congress participants who are interested in a particular topic in mathematics education. The word ‘study’ suggests that the activities of the groups will include presentations and discussions of important new trends and developments in research or practice related to the topic under consideration. Each TSG will be organised by a team of five prominent experts in the field. Two chairs have been appointed for each team. They are listed below with e-mail addresses. The teams are described when completed. Please see each team individually. The purpose of the TSGs is to provide both an overview of the current state-of-the-art in the topic, and expositions of outstanding recent contributions to it, as seen from an international perspective. By their very nature, some of the topics are focused more on research than on practice. For others the opposite will be the case, whereas several topics will have a fairly equal balance of the two.

To some extent, a number of the topics in the list for the Topic Study Groups have mutual overlaps with other topics. Even so, each topic has a well-defined and specific ‘centre of gravity’ that makes it clearly discernible from the others in the list.

The list of topics is organised into four clusters. The first cluster, TSG 1-7, consists of Topic Study Groups that focus on the target groups of mathematics teaching as reflected in educational levels and special categories of students. The next cluster, TSG 8-21, focuses on matters and issues pertaining to content-related aspects of mathematics curricula, across educational levels, and to teaching and learning in relation to those aspects. The cluster formed by TSG 22-27 deals with the overarching perspectives and facets of mathematics education that are present across different educational levels and different curricula. Finally, TSG 28-29 are the Groups in which meta-issues concerning mathematics education itself, as a field of practice and a discipline of research, are the focus of attention.

The TSGs will have three one-hour timeslots and one ninety-minute timeslot in the congress timetable at their disposal. Each TSG organising team will have the responsibility of updating the web site linked to the congress web site. On this site it will be possible to follow the planning process and eventually access all relevant documents including the timetable for TSG sessions. Participants who would like to present papers in a TSG are requested to communicate with the team chairs. The TSG teams are responsible for establishing a scheme for paper presentation by distribution, see "How to contribute". Typically proposals should be put forward before January 1, but specific guidelines, if such apply, will be made available on the web site.
