Social interaction is a central mechanism through which students construct knowledge, sustain motivation, and improve academic performance. This review-based article synthesizes evidence from ten influential studies and meta-analyses on peer interaction, teacher–student relationships, classroom social networks, and online learning interactions. Across the literature, positive social interaction is consistently associated with better engagement, stronger motivation, and improved academic outcomes. Meta-analytic findings show moderate positive effects of peer interaction and teacher–student relationship quality on learning, while recent studies demonstrate that these effects are often mediated by social presence, learning engagement, and perceived usefulness of learning environments. The evidence also suggests that the quality and structure of interaction matter: dialogic, supportive, and consensus-oriented interactions are more beneficial than superficial or conflictual exchanges. The review concludes that schools and educators should intentionally design socially rich learning environments—both face-to-face and online—to maximize student learning outcomes.
