At the Madif11 (MathematicsDidactical Research Seminar in Karlstad 2018), the FoNS team presented a study of how teachers regard their and parents' role in mathematics homework. Internationally and in Sweden, teachers often motivate homework with practice, good habits, teacher communication to parents, etc., but a specific Swedish contribution is that teachers use equality as an argument both for and against homework. Teachers who set homework view it as extra support and those who do not set homework motivate their position with equality - students do not have the same opportunity to get help at home with their homework.
