Motivation is a complex process with multiple factors that influence a learner's persistence and commitment to learning a language. It involves three main phases - choice motivation, executive motivation, and motivational retrospection. Key aspects of motivation include integrative and instrumental orientation, self-confidence, beliefs about success, and perceptions of the learning experience. Motivation can be influenced by both intrinsic and extrinsic factors and is an important consideration for language teachers in generating initial motivation, maintaining effort, and facilitating positive self-evaluation among students.
