Learning is always a core activity in forming cognitive abilities and personality traits in people's growth process, and motivation is the key psychological mechanism that drives learning behaviour. Therefore, motivation in learning is an important area of research in educational psychology. It not only determines the initiation and continuation of learning but also affects the effectiveness and depth of learning. The complexity of motivation in learning lies in its multidimensional composition and dynamic changes, making its in-depth study an important area of research in psychology, education and other disciplines. Under the title "Motivation in Learning," this book systematically analyses the nature of motivation and its formation mechanism and manifestations in different learning (educational) contexts. The book attempts to provide a comprehensive and dynamic introduction to the application and interpretation of the theory of motivation in learning and to provide a solid theoretical foundation for subsequent research.
