Mathematics is a core competency that plays an important role in educational and professional success. The fact that particularly students in adolescence experience motivational slumps in mathematics reinforces the necessity of fostering motivation for mathematics. Initial US studies indicate that it is possible to favorably influence the motivation of students with the help of a simple intervention conducted in a classroom context.

The purpose of the project is to examine how well the motivation in mathematics instruction of 9th grade students can be enhanced based on these established intervention approaches.
