AODs are a type of educational environment that exists within online learning platforms. Their main purpose is to provide students with a space where they can create their own understanding and ideas within their own minds and physical surroundings. Additionally, they offer opportunities for students to interact with others in a community of learners, where they can collaborate and construct knowledge together.
