In the topic study group on probability at ICME 11 a variety of ideas on probability education were presented. In an international, collaborative, project after the conference, many of these papers have been developed much further, incorporating novel electronic techniques, which also feature in this paper, with links to many references rather than a simple listing. This joint presentation provides a summary of the main threads of research in probability education across the world; there is a linked paper on possibilities of electronic communication (The future of interactive electronic research). This paper provides an incisive and reflective summary on which researchers can build, while the latter enables developments relevant for other areas of research too. Hyperlinks are included throughout.
