Abstract
Constructivist pedagogy positions learners as active sense‑makers who negotiate, justify, and revise mathematical ideas through interaction with tasks, peers, tools, and teachers. In India, although policy blueprints such as the NCF 2005 endorse child‑centred, inquiry-rich mathematics, everyday practice still leans on algorithmic drill and summative testing. This study interrogates that policy–practice gap by (a) synthesizing global and Indian literature on constructivist mathematics teaching, and (b) reporting findings from an eight‑week, mixed‑methods intervention across nine diverse schools in Maharashtra, Tamil Nadu, and Uttar Pradesh (N = 360; Grades 6–8). Quantitative analyses (paired t‑tests, ANCOVA) revealed large, statistically significant gains in conceptual understanding (Cohen’s d = 1.07) and problem‑solving (d = 0.95). Attitudinal shifts were equally notable—62% of learners reported reduced mathematics anxiety and 71% affirmed that peer discussion helped mathematics “make sense.” Qualitative evidence from classroom observations, teacher journals, and student focus groups illuminated four catalytic processes: dialogic discourse, material/contextual mediation, embedded formative assessment, and peer scaffolding. Yet, systemic constraints—oversized classes, exam pressure, pacing guides, and limited teacher autonomy—tempered the breadth and durability of change. The paper argues for a contextually adapted constructivism that leverages multilingual resources, culturally familiar problem contexts, and low‑cost manipulatives, while aligning assessment regimes with reasoning and representation. Recommendations include sustained professional development focused on discourse moves and task design, collaborative planning time for teachers, and policy-level assessment innovation. Future research should examine technology-enabled constructivism, longitudinal retention and transfer, and equity-focused analyses of discourse to ensure that the benefits of constructivist mathematics reach all learners.
