Social Constructivism proposes that meaningful learning occurs through social interactions. According to this theory, knowledge is constructed by learners based on their experiences. Lev Vygotsky was a major proponent and believed that cognitive development is influenced by social and cultural factors like language, tools, and social interactions. In education, the social constructivist approach involves engaging students in collaborative activities based on real-world problems and facilitating cognitive growth through social guidance and support. Online learning can incorporate social constructivist principles through tools that enable collaboration, discussion, and sharing of projects.
