Dan Keast describes his implementation of constructivism in an online two-course music history series. He discusses developing the courses with editors and reviewers to include constructivist techniques like student-centered activities and assessments. Key learning theories like constructivism, scaffolding, Vygotsky's zone of proximal development, and activity theory formed the foundation. The online courses allow asynchronous access to high quality music examples and generate discussion. Keast calls for more research on online music education practices.
