Introduction to the work of TWG05: Probability and Statistics Education

The core of the conference is the thematic working groups (TWG) in which new, related research studies are discussed, based on papers which participants read in advance. While this format has remained almost unchanged since 1998, the scale and scope of CERME have developed considerably over the years: from 120 participants and 7 TWG at CERME 1, to 915 participants and 27 TWG at CERME 12. Moreover, CERME has gone from being a mainly regional congress (with only a few participants from other continents) to being a truly global event in mathematics education research, known for fostering high quality scientific communication, cooperation and collaboration. At CERME12, no less than 48 nations were represented
