Adolescence is a critical phase characterized by rapid psychosocial and emotional changes, significantly influenced by educational settings. This article explores the methodologies employed in studying the psychosocial behavior of adolescents in education, drawing review on qualitative, quantitative, and mixedmethod research designs. Theoretical frameworks such as Erikson's psychosocial development theory, Bandura's social cognitive theory, and Bronfenbrenner's ecological systems theory provide a foundation for understanding these behaviors. The article highlights the importance of integrating contextual and cultural considerations into research while ensuring methodological rigor through validated tools and strong designs. Findings emphasize the multidimensional nature of adolescent psychosocial behavior and the need for comprehensive research methodologies to inform educational practices and policies.
