**Reasoning and proof in mathematics education**

Hamburg, Germany July 24-31, 2016

A Topic Study Group about proof is included at the 13th International Congress on Mathematical Education (ICME-13).

Co-chairs:

Guershon Harel (USA)

Andreas Stylianides (UK)

There is international recognition of the importance of reasoning and proof in students’ learning of mathematics at all levels of education, and of the difficulties met by students and teachers
in this area. A rapidly expanding body of research has offered important insights into this area, but there are still many open questions for which theoretical and empirically based responses
are sorely needed. TSG 18 will offer a forum for an overview of the state of the art, invited contributions from experts in the field, presentation
of high-quality, research reports from TSG participants, and discussion of directions for future research.
Deadline for the Submission of Papers and Posters: **15 Ottobre 2015**.

**ESPE de Nice Célestin Freinet, Centre Stephen Liégeard

**First INDRUM Conference,
March 31 – April 2, 2016, Montpellier, France.**

INDRUM 2016 is the first in a series of biennial and bilingual1conferences that will address all aspects of research in didactics of mathematics at tertiary level, including students' and teachers' practices and the teaching and learning of specific mathematical topics. The conference aims to attract researchers in didactics of mathematics at university level, mathematicians and any teacher or researcher with interest in university mathematics education

TWG2 is about Teaching and learning of topics in university mathematics, including logic, reasoning and proof
Deadline for submission of papers or of poster proposals is **November 20**.
