UPDATE: We have two more confirmed speaker names to throw into the hat. These are:
Rachel Linney, Education Officer for the Irish National Council of Curriculum and Assessment. Expect big maths curriculum changes from Dublin soon enough!
Also on the speaker list is Kristian Smedlund of the Finnish National Board of Education. Computer-Based Maths has close links with Scandinavia, having run its pilot in Estonia and having also been adopted by the Fria Laroverken schools in Sweden.
