Topic Study Group 31 (TSG 31) for ICME-12: Tasks Design and Analysis

The TSG 31 organizing committee is co-chaired by
Team chairs: Xuhua Sun (China) and Lalina
Coulange (France) with team members: Eddie
Chi-keung Leung (Hong Kong) ckleung@ied.edu.hk,
Nguyen Chi Tanh (Vietnam) thanhnc70@yahoo.com,
Hea-Jin Lee (Korea) lee.1129@osu.edu, along with
IPC Liaison Masataka Koyama.

The organizing committee assembled the accepted
papers for TSG 31 into four groups for summary,
presentation, and discussion:

Group A: Dynamic Geometry Environments and the Role of Representations
Group B: Categorizations of Tasks and Textbooks
Group C: Tasks Enacted by the Teacher and Students
Group D: Discoveries and Justifications

The following timetable for TSG 31 provides details on the schedule.
