Reflective thinking and practitioner inquiry are vital for enhancing educational practices. They enable teachers to evaluate their methods and adapt to learners' diverse needs. Grounded in educational theories such as Schön’s reflective model, Kolb’s experiential learning cycle, and constructivist principles, these approaches promote a systematic process of planning, teaching, reviewing, and refining instructional strategies to improve student outcomes and engagement. This study explores how reflective thinking, integrated within a practitioner inquiry framework, can refine instructional practices, address diverse learner needs, and enhance the learning experience. It examines the synergy between these approaches in fostering professional growth and effective teaching. A qualitative practitioner inquiry approach, incorporating action research principles, was employed. Data was collected through classroom observations, student feedback, and teacher reflective notes, triangulated to provide a robust understanding of the impact of reflective practices. This iterative process of planning, teaching, and reflecting allowed for real-time adjustments and systematic improvements in instructional strategies. The study found that reflective thinking enhances teacher adaptability, enabling real-time responses to diverse student needs. Multimodal instructional approaches, informed by theories such as Gardner’s Multiple Intelligences and VARK, effectively engaged students but required a balanced integration of digital tools to avoid cognitive overload. Pre-lesson needs assessments significantly improved lesson inclusivity and effectiveness, while collaborative professional development enriched reflective practices and knowledge sharing among educators. Reflective thinking and practitioner inquiry empower educators to create adaptive, inclusive, and effective learning environments. These approaches facilitate continuous professional development and improved student outcomes by combining evidence-based practices with educational theory. The findings highlight the need for structured reflective practices, careful selection of instructional tools, and regular needs assessments to tailor lessons to diverse learners. Collaboration among educators is essential for fostering professional growth and refining teaching methodologies. Future research should address the long-term impact of reflective practices on student achievement and explore strategies for overcoming technological and contextual limitations in classrooms.
