Still, there are no clear guidelines teachers can use to contribute to the intrinsic motivation of their students. The goal of this literature review was to provide concrete guidelines that teachers can use to contribute to the intrinsic motivation of their primary school students. This was done firstly by identifying concrete actions that teachers can use to contribute to the intrinsic motivation of their students, according to the selfdetermination theory. Secondly literature research focused on how big the effect sizes matching with these concrete actions were. A systematic search yielded five studies that were eligible. However there were studies included in the study that had a different student population than primary school students, which were highschool- and university students. The results indicated that there were no huge differences in the outcomes of the studies with different student populations. Results of the concrete actions teachers can use to contribute to their students' intrinsic motivation can be categorised by the basic needs of the selfdetermination theory. When it comes to autonomy, this research indicates that teachers should give their students valuable choices during their learning process. The bond or relationship can be improved by showing affection, respect and by being understanding. The research also indicates that teachers should try to match teaching with the personal interest of the students. When it comes to competence, research indicates that teachers should offer activities to their students that match their current competence. Communication, expectations and positive feedback are also key, when it comes to competence, according to the literature research.Show less
