The last seven years have been devoted to studies in educational sciences specialising in didactics of mathematics. Research has focused on the reasons why students show low performance in mathematics. The project intends designing course materials for the instruction of how to teach such students. Via separate training days in the 11 municipalities of Northwest Skåne, this pedagogic method will be introduced in the municipalities where the empirical data for the forthcoming thesis has been collected. In this project a popular version of the doctoral thesis is used, written so that it caters to working teachers and with a supplement that contains methodology on how we can work with measures for students with low achievement in mathematics. Experience from these programmes will be included in the methodological section in a forthcoming textbook.
