Participants are invited to submit presentations in the form of posters at ICME-12. A wide array of topics and initiatives in mathematics education research or practice are possible themes for poster presentations. Posters may be presented in any of the four languages: English, Korean, Chinese and Japanese.

The exhibition space for posters can accommodate several hundred posters, will be highly accessible and well-located in central areas of the Congress activity. Posters will be on display for two or more days of the Congress. Time slots will be allocated for presentations and authors must choose one of the two modes of presentation, either oral presentation or Round Table Discussion. Round Table Discussions will be listed in the final program for ICME-12. The IPC will appoint experienced mathematics educators to chair the Round Table Discussions.

The posters and the presentations will be grouped, as far as possible, according to language and according to the themes of the 37 Topic Study Groups. Although this is optional, authors are invited to indicate the Topic Study Group that their poster most closely relates to. Posters connected to Topic Study Groups will potentially have the benefit of an audience related to the TSG.

Information about the size and format of posters will be given when a poster has been accepted, and will be posted on the 'Poster Presentations' webpage. Presenters should use a font of at least 24 points so as to make the posters readable at a distance of 1.5 meters. Poster presenters should consider using both textual and visual means of presentation in their posters. The congress will not be able to provide poster supplies or material on site beyond space, and adhesive tape.

Authors proposing to present posters need to complete an online form, submit an abstract of the poster written in text form of 300 to 500 words and include a title and keywords before 15th December 2011. The abstracts need to be in English even if the poster is to be presented in another language.
