Summary It is a fact that teachers have profound impact on student motivation but theories about the best practice and the pedagogical methods to achieve this vary. Instead of technical, teacher-centered, direct instructions that will suppress inquiry-based learning, our project builds on student-centered instructions to shape the students' mindset towards the belief that their own initiatives matter - a growth mindset. By helping students to develop a growth mindset, teachers make teaching - and learning - more effective. Growth mindset students request better feedback and have better learning orientation. They also show grit more often and thus persist longer. This project is an upgrade of the previous successful project MindSet Go! - where the partners developed lesson plans based on a growth mindset. This project aims higher as we want to change the culture and learning environment at schools and also have an impact on parents. Teacher trainers and partner schools from Sweden,
