Feedback from teachers is of great importance for the learning development of pupils. For optimal support of learning processes, it is important how students perceive and utilise feedback. Based on theoretical supply-utilisation models, this book addresses the question of the extent to which students in upper secondary school perceive feedback from teachers in German lessons differently and how this perception affects students' motivation development. The findings from latent change models provide information on the stability and change in feedback perception over the course of a school term as well as on differences in feedback perception between students. In addition, the longitudinal analyses highlight the interplay between different dimensions of feedback quality and the development of learning motivation. The findings expand the state of research on the perception of feedback and the development of differentiated effects on motivation and also open up a wide range of suggestions for educational practice.
