The transformation of the Indian education system in the 21st century requires a shift from traditional teacher-centered pedagogies to learner-centered approaches that promote critical thinking, creativity, and holistic development. The constructivist approach, rooted in the works of theorists such as Jean Piaget and Lev Vygotsky, emphasizes active learning, experiential engagement, and knowledge construction through social interaction. This research paper examines the need for re-imagining teaching in India through the constructivist framework in the context of policy reforms such as the National Curriculum Framework (NCF 2005) and the National Education Policy (NEP 2020). The study adopts a qualitative methodology based on secondary data analysis of research papers, policy documents, and scholarly articles. It explores classroom practices, benefits, challenges, and implementation strategies of constructivism in Indian education. The findings reveal that while constructivist pedagogy enhances student engagement and conceptual understanding, its effective implementation is hindered by systemic challenges such as rigid curricula, large class sizes, and insufficient teacher training. The paper concludes with recommendations for strengthening constructivist practices to create a more inclusive, innovative, and future-ready education system in India
