The teaching–learning process is greatly influenced by psychological factors that shape both teacher performance and student outcomes. This study examines the relationship between intrinsic motivation, self-efficacy, and teacher-evolved methods in classroom instruction. Intrinsic motivation, which drives teachers to engage in their profession for internal satisfaction and personal growth, enhances creativity and commitment in pedagogical practices. Self-efficacy strengthens teachers’ belief in their ability to plan, organize, and execute effective teaching strategies. When combined, these factors encourage teachers to develop innovative, context-specific methods that cater to learners’ needs. The paper explores how teacher-evolved methods emerge from reflective practice, autonomy, and continuous professional development. The findings highlight that highly motivated and self-efficacious teachers are more likely to adopt flexible, student-centred approaches, leading to improved engagement and academic achievement. Implications for professional development and institutional support are also discussed.
