This course will examine the theory and research underlying key learning theories that have informed online design, including constructivist learning and its historical and philosophical roots. We will consider various learning approaches that have informed these ideas, like problem based learning, collaborative learning and knowledge building, as well as more recent perspectives, including Universal Design for Learning and equity and inclusion considerations for creating safe online experiences for all students.  We will examine how such concepts can inform and enhance the design and pedagogy of online environments.
