Abstract
A critical topic in mathematics education is the design and analysis of open-ended, realistic, and exemplary tasks. Task design and analysis is a relatively new field, appearing for the first time as a topic of study (TSG 34) at ICME-11 in Monterrey, Mexico. It is developing quickly and dynamically as an area of international attention and active research.

Aims
A critical topic in mathematics education is the design and analysis of open-ended, realistic, and exemplary tasks. Task design and analysis is a relatively new field, appearing for the first time as a topic of study (TSG 34) at ICME-11 in Monterrey, Mexico. It is developing quickly and dynamically as an area of international attention and active research.
Topic Study Group 31 will bring together researchers, developers and teachers who systematically investigate and develop theoretical and practical accounts of task design and analysis. We welcome proposals from both researchers and practitioners and encourage contributions from all countries. Presentations and discussions will target new trends, new understanding, and new developments in research and practice.
We have a particular interest in empirically grounded contributions that underline design principles and theoretical approaches, and give examples of tasks designed for promoting mathematical development. We plan to discuss (but are not limited to) the following themes:
-
Theoretical and practical development that guides task design and analysis
-
Diverse theoretical approaches or principles that guide task design and analysis
-
Diverse practical traditions/approaches that guide task design/analysis and their theoretical accounts
-
Examples of task analysis for studying the relations between tasks, psychological development, and mathematical development
-
Critical literature studies or meta-analysis of task design and analysis
The group will welcome contributions that focus on primary or secondary education. Research and development in task design and analysis presented at ICME-11 is retrievable at (http://tsg.icme11.org/tsg/show/35).
Organizations
On the website of ICME-12 it was possible to follow the planning process and eventually access all relevant documents including the timetable for TSG sessions. Each Session has four 90 min timeslots (on Tuesday, Wednesday, Friday and Saturday mornings). This made TSGs the prime forum for participation. We expected that participants engage in the review process prior to the conference, and we nominated respondents to all presentations in order to enable deeper levels of critical discussion during the conference. The presenters worked in pairs and made short comments or elaborated on each other’s work after every presentation. In this way, TSG 31 was an active study group.
Submissions and Theme
The organizing committee received 12 submissions with 100 % acceptance rate (11 short oral presentations and 1 poster). The organizing committee assembled the accepted papers for TSG 31 into four groups for summary, presentation, and discussion:
-
Dynamic Geometry Environments and the Role of Representations
-
Categorizations of Tasks and Textbooks
-
Tasks Enacted by the Teacher and Students
-
Discoveries and Justifications
