By utilising on-line communication technology, The ANAMOL project aimed to address the problems of numeracy teachers who often work in isolated situations. Teachers from four states communicated both on a weekly basis using 'chat' technology, and irregularly via web- based discussion forum. Through these discussions, teaching materials were written, trialled, refined and published on a newly- developed website. This report documents the action research methodology used, the project outcomes and implications and recommendations for further on-line professional development.
