MixEd investigates the effects of student selection and class formation on learning, motivation, and students' school paths. The project consists of three work packages: the first involves a systematic literature review across disciplines. The second collects longitudinal student data (n~6000) to study how class formation impacts the development of learning and motivation. This data will also be combined with regional information from the YKR registry to analyze the association between selective student grouping and school and residential segregation, as well as with data from the national registry of upper secondary school admissions to analyze students' school paths. The third work package examines the mechanisms through which class formation influences learning, using intensive data collected from teachers and students. This package focuses on the teacher's role, teacher-student interaction, and peer relationships in various classroom environments.
