The document discusses social constructivism, a theory by Lev Vygotsky that emphasizes the importance of social interactions in learning and highlights the role of teachers in facilitating student development through the zone of proximal development. It also describes Universal Design for Learning (UDL), developed by Dr. David Rose and Dr. Ann Meyer, which aims to accommodate diverse learners by providing multiple means of representation, expression, and engagement to create an inclusive educational environment. Both approaches focus on active, learner-centered methodologies that enhance understanding and promote collaboration among students.
