These forms of intrinsic motivation seem to disappear when children start to attend school. The objectives in schools are generally focused on memorizing knowledge instead of the process of learning. To achieve differentiation in the classroom, studies show that stimulating executive functioning and intrinsic motivation in children could lead to better school achievements. Aim: The aim of the present study was to test if a teacher intervention focused on explorative behavior in children, would lead to higher levels of executive functioning and intrinsic motivation in children. Method: Teachers from four different elementary schools and 211 children (8-12 years) with their parents participated in a baseline and a follow-up assessment six months later. During both assessments two questionnaires were filled out by children on their motivation (Prestatie Motivatie Test voor Kinderen) and by parents on the children’s executive functioning (Behavior Rating Inventory of Executive Function). After the baseline assessment the teacher intervention took place. The teachers learned about the development of the brain and how they could stimulate higher thinking processes, social cognition and explorative behavior in children. Results: A correlation was found between intrinsic motivation and the executive functions cognitive flexibility and working memory. Meaning that overall children with increased motivation also showed fewer problems with executive functioning. However, the teacher intervention showed no significant effects on either intrinsic motivation or executive functioning. Conclusion: This research showed that not only extrinsic motivation, but also intrinsic motivation correlates with the executive functions. Although these correlations were found, the teacher intervention showed no significant main effect. To monitor the effects of the teacher intervention more time and feedback is needed. Through longitudinal research behavioral changes in teachers and students can be monitored over time.Show less
