This article comprehensively examines the impact of various interior design elements—such as color, lighting, ventilation, acoustics, layout, furniture, and material selection—on students' behavior, psychology, and academic performance in educational environments. The main objective of the research is to analyze the role of physical environments in enhancing learning quality, mental health, social development, and creativity, and to provide practical solutions for improving school interior design. The research methodology is mixed (theoretical and field-based), combining a literature review with interviews with teachers, distribution of questionnaires among students and teachers, direct observation, and statistical data analysis. The findings reveal that a well-designed physical environment can enhance motivation, reduce stress, improve concentration, foster social interaction, develop talents, and boost academic performance. The study also emphasizes the importance of natural light, purposeful color schemes, proper ventilation, noise control, flexible layouts, and human-centered design in educational spaces. Practical recommendations for creating effective, dynamic, and inspiring learning environments are provided at the end.
